Importance of revealing a rare case of breast cancer in a female to male transsexual after bilateral mastectomy

The incidence of breast carcinoma following prophylactic mastectomy is probably less than 2%. We present a 43-year-old female to male transsexual who developed breast cancer 1 year after bilateral nipple- sparing subcutaneous mastectomy as part of female to male gender reassignment surgery. In addition to gender reassignment surgery, total abdominal hysterectomy with bilateral salpingo-oophorectomy (to avoid the patient from entering menopause and to eliminate any subsequent risk of iatrogenic endometrial carcinoma), colpocleisys, metoidioplasty, phalloplasty, urethroplasty together with scrotoplasty/placement of testicular prosthesis and perineoplasty were also performed.Before the sex change surgery, the following diagnostic procedures were performed: breast ultrasound and mammography (which were normal), lung radiography (also normal) together with abdominal ultrasound examination, biochemical analysis of the blood and hormonal status.According to medical literature, in the last 50 years only three papers have been published with four cases of breast cancer in transsexual female to male patients.All hormonal pathways included in this complex hormonal and surgical procedure of transgender surgery have important implications for women undergoing prophylactic mastectomy because of a high risk of possible breast cancer.

Primitive neuroectodermal tumor of the kidney: case report and review of literature

Background: Renal primitive neuroectodermal tumor (rPNET) as a member of Ewing's sarcoma family is extremely rare and usually occurs in children and young adults. Most literature about rPNET was isolated case reports.Case presentationWe reported a case of 45-year-old man with the complaint of right flank pain. Computerized tomography (CT) scan demonstrated a large substantive tumor involving the lower pole of the right kidney. Then the patient underwent radical nephrectomy. Pathologic characteristics and immunohistochemical analysis confirmed the diagnosis of rPNET. Additionally, the patient received three cycles of chemotherapy, and was still alive without metastasis at 15-months follow-up. Conclusion: rPNET is rare and presents aggressive clinical behavior and worse prognosis. We expect that further awareness and study of this rare tumor can be had by presenting our case.

Falciform ligament abscess from left sided portal pyaemia following malignant obstructive cholangitis

Abscess formation of the falciform ligament is incredibly rare and perplexing when encountered for the first time. It is reported to occur in the setting of cholecystitis and cholangitis, but the pathophysiology is poorly understood.In this case report, we present a 73-year-old man with falciform ligament abscess following cholangitis from an obstructive ampullary carcinoma. The patient was referred to the Royal Adelaide Hospital from a country hospital, with progressive jaundice, anorexia and nausea. Prior to transfer, he deteriorated with cholangitis, dehydration and renal failure. On arrival, his abdomen was exquisitely tender along the course of the falciform ligament. His blood tests revealed an elevated white cell count of 14.9 x 103/mul, bilirubin of 17 mg/dl and creatinine of 347 mumol/l. His CA 19-9 was markedly elevated at 35,000 kU/l. A non-contrast computed tomography (CT) demonstrated gross biliary dilatation and a fluid collection tracking along the path of the falciform ligament to the umbilicus.The patient was commenced on intravenous antibiotics and underwent an urgent endoscopic retrograde cholangiopancreatogram (ERCP) with sphincterotomy and biliary stent drainage. Cholangiogram revealed a grossly dilated biliary tree, with abrupt transition at the ampulla, which on biopsy confirmed an obstructing ampullary carcinoma. Following ERCP, his jaundice and abdominal tenderness resolved. He was optimized over 4 weeks for an elective pancreaticoduodenectomy.At operation, we found abscess transformation of the falciform ligament. Copious amounts of pus and necrotic material was drained. Part of the round ligament was resected along the undersurface of the liver. Histology showed that there was prominent histiocytic inflammation with granular acellular eosinophilic components. The patient recovered slowly but uneventfully.A contrast CT scan undertaken 2 weeks post-operatively (approximately 7 weeks after the initial CT) revealed left portal venous thrombosis, which was likely to be a delayed discovery and was managed conservatively.We present this patient's operative images and radiographic findings, which may explain the pathophysiology behind this rare complication. We hypothesize that cholangitis, with secondary portal pyaemia and tracking via the paraumbilical veins, can cause infectious seeding of the falciform ligament, with consequent abscess formation.

Down-regulation of cellular FLICE-inhibitory protein (Long Form) contributes to apoptosis induced by Hsp90 inhibition in human lung cancer cells

Background: Cellular FLICE-Inhibitory Protein (long form, c-FLIPL) is a critical negative regulator of death receptor-mediated apoptosis. Overexpression of c-FLIPL has been reported in many cancer cell lines and is associated with chemoresistance. In contrast, down-regulation of c-FLIP may drive cancer cells into cellular apoptosis. This study aims to demonstrate that inhibition of the heat shock protein 90 (Hsp90) either by inhibitors geldanamycin/17-N-Allylamino-17-demethoxygeldanamycin (GA/17-AAG) or siRNA technique in human lung cancer cells induces c-FLIPL degradation and cellular apoptosis through C-terminus of Hsp70-interacting protein (CHIP)-mediated mechanisms. Methods: Calu-1 and H157 cell lines (including H157-c-FLIPL overexpressing c-FLIPL and control cell H157-lacZ) were treated with 17-AAG and the cell lysates were prepared to detect the given proteins by Western Blot and the cell survival was assayed by SRB assay. CHIP and Hsp90 alpha/beta proteins were knocked down by siRNA technique. CHIP and c-FLIPL plasmids were transfected into cells and immunoprecipitation experiments were performed to testify the interactions between c-FLIPL, CHIP and Hsp90. Results: c-FLIPL down-regulation induced by 17-AAG can be reversed with the proteasome inhibitor MG132, which suggested that c-FLIPL degradation is mediated by a ubiquitin-proteasome system. Inhibition of Hsp90alpha/beta reduced c-FLIPL level, whereas knocking down CHIP expression with siRNA technique inhibited c-FLIPL degradation. Furthermore, c-FLIPL and CHIP were co-precipitated in the IP complexes. In addition, overexpression of c-FLIPL can rescue cancer cells from apoptosis. When 17-AAG was combined with an anti-cancer agent celecoxib(CCB), c-FLIPL level declined further and there was a higher degree of caspase activation. Conclusion: We have elucidated c-FLIPL degradation contributes to apoptosis induced by Hsp90 inhibition, suggesting c-FLIP and Hsp90 may be the promising combined targets in human lung cancer treatment.

Secure hemostasis in transhiatal esophagectomy for esophageal cancer with gauze packing

Background: Transhiatal esophagectomy for esophageal cancer implies blind manipulation of the intrathoracic esophagus. We report a secure hemostatic method with gauze packing in transhiatal esophagectomy. Methods: The gauze-packing technique is utilized for hemostasis just after removal of the thoracic esophagus during transhiatal esophagectomy. After confirming cancer-free margins, the abdominal esophagus and cervical esophagus are transected. A vein stripper is inserted into the oral-side stump of the esophagus and led to exit from the abdominal-side stump of the esophagus. The vein stripper and the oral stump of the esophagus are affixed by silk thread. A polyester tape is then affixed to the vein stripper, as the polyester tape is left in the posterior mediastinum after removal of the esophagus toward the abdominal side. The polyester tape on the cervical side is ligated with gauze and the polyester tape is removed toward the abdominal side. The oral stump of gauze and new additional gauze are affixed. As the first gauze is pulled out from the abdominal side, the second gauze gets drawn from the cervical wound into the mediastinum. The posterior mediastinum is finally packed with gauze and possible bleeding at this site undergoes a complete astriction. The status of hemostasis with the gauze packing is checked by an observation of color and bloodstain on the gauze. Results: Between January 2005 and February 2012, 13 consecutive patients with esophageal cancer underwent a transhiatal esophagectomy with the gauze-packing hemostatic technique. Hemostasis at the posterior mediastinum was performed successfully and quickly in all cases with this method, requiring up to four pieces of gauze for a complete hemostasis. Median required time for hemostasis was 1219 (range 1896 to 1293) seconds and estimated blood loss was 20.4 (range 15 to 25) ml during gauze packing. Conclusions: Our technique could minimize bleeding after the removal of the thoracic esophagus. The gauze-packing method is a simple and easy technique for secure hemostasis when performing a transhiatal esophagectomy.

Collagen sealant patch to reduce lymphatic drainage after lymph node dissection

Background: Seroma formation is a frequent complication following radical lymph node dissection (RLND) in patients with metastatic melanoma. Several strategies have been used to prevent fluid accumulation and thereby reduce the duration of postoperative drainage, including fibrin sealants. Methods: This was a prospective, single-center study in which consecutive patients undergoing surgical treatment of stage III metastatic melanoma by axillary or ilio-inguinal RLND were randomized to receive standard treatment plus fibrinogen/thrombin-coated collagen sealant patch (CSP) or standard treatment alone. The primary endpoint of the study was postoperative duration of drainage. Results: A total of 70 patients underwent axillary (n=47) or ilio-inguinal (n=23) RLND and received CSP plus standard treatment (n=37) or standard treatment alone (n=33). Mean duration of drainage was significantly reduced in the CSP group compared with standard treatment (ITT analysis: 20.1 +/- 5.1 versus 23.3 +/- 5.1 days; p=0.010). The percentage of patients drainage-free on day 21 was significantly higher in the CSP group compared with the standard treatment group (86% versus 67%; p=0.049). Conclusions: Use of the tissue sealant resulted in a significant reduction in duration of drainage. Further studies are warranted to confirm these results in different and selected types of lymphadenectomy.

Antitumor activity of the selective cyclooxygenase-2 inhibitor, celecoxib, on breast cancer in Vitro and in Vivo

Background: Cyclooxygenase-2(COX-2) promotes carcinogenesis, tumor proliferation, angiogenesis, prevention of apoptosis, and immunosuppression. Meanwhile, COX-2 over-expression has been associated with tumor behavior and prognosis in several cancers. This study investigated the antitumor effects of the selective COX-2 inhibitor, Celecoxib, on breast cancer in vitro and in vivo. Methods: Human breast cancer MCF-7 and MDA-MB-231 cells were cultured with different concentration (10, 20, 40mumol/L) of celecoxib after 0-96 hours in vitro. MTT assay was used to determine the growth inhibition of breast cancer cells in vitro. The expression of COX-2 on mRNA was measured by real-time quantitive PCR analysis. Flow cytometry was performed to analyze the cell cycle of MCF-7 cells. Levels of PGE2 were measured by ELISA method. The in vivo therapeutic effects of celecoxib were determined using rat breast cancer chemically induced by 7,12-dimethylben anthracene (DMBA). Results: The inhibition of proliferation of both MCF-7 and MDA-MB-231 cells in vitro by celecoxib was observerd in time and dose dependent manner. Celecoxib effectively down-regulated the expression of COX-2. The cell cycle was arrested at G0/G1, and rate of cells in S phase was obviously decreased. Levels of PGE2 were inhibited by Celecoxib. The tumor incidence rate of the celecoxib group was lower than that of the control group. In addition, the tumor latency period of the celecoxib group was longer than that of the control group. Conclusions: Celecoxib inhibited the proliferation of breast cancer cell lines in vitro, and prevented the occurrence of rat breast cancer chemically induced by DMBA. Therefore, celecoxib exhibits an antitumor activity and seems to be effective in anti-tumor therapy.

Prognosis significance of HER-2/neu overexpression/amplification in Chinese patients with curatively resected gastric cancer after the ToGA clinical trial

Background: HER-2/neu-targeted therapy has been successfully used in advanced gastric cancer, but the role of HER-2/neu in the prognosis of gastric cancer is not yet clear. In this study, we investigated the correlation between HER-2/neu expression and amplification as well as their association with clinic outcomes in patients with curatively resected gastric cancer. Methods: We constructed tissue microarray blocks containing >70% of gastric cancer tissue and matched adjacent normal gastric tissue for 227 patients. Expression of the HER-2/neu protein in these specimens was analyzed using immunohistochemical staining. Amplification of HER-2/neu was also analyzed for the same samples using fluorescence in situ hybridization. Data on clinicopathological features and relevant prognostic factors in these patients were analyzed. Results: Of the 227 gastric cancer samples, 11.89% were positive for HER-2/neu overexpression/amplification under the new scoring system. HER-2/neu overexpression/amplification was closely correlated to the Lauren type, degree of differentiation, tumor size and lymph node metastasis. HER-2/neu overexpression/amplification predicted poor survival in univariate analysis but not in a Cox proportional hazards model. Conclusion: HER-2/neu overexpression/amplification was not an independent predictor for survival in patients with curatively resected gastric cancer.

Analysis of the tumor length and other prognosis factors in pT1-2 node-negative esophageal squamous cell carcinoma in a Chinese population

Background: Tumor length is an important prognostic factor for many carcinomas, but its role in esophageal cancer remained undetermined. The aim of this study was to investigate the effect of tumor length on survival for patients with confined tumors (grade pT1-2) without lymph-node metastases in esophageal squamous cell carcinoma. Methods: We enrolled 201 patients with esophageal squamous cell carcinoma (SCC) who had undergone surgical resection and been confirmed as pT1-2N0M0. The relationship of tumor length with overall survival was assessed and compared with other factors detailed in the American Joint Committee on Cancer (AJCC) tumor, node, metastasis (TNM) staging system published in 2009. Results: The overall survival (OS) rates at 1, 3, and 5 years were 93.0%, 83.7%, and 69.2%, respectively. The tumor length adversely affected OS, with the 5-year rate being 93.5%, 82.0%, 68.6%, 67.9%, 55.3% and 41.1%, respectively for tumor lengths of less than 10 mm, 10 to 20 mm, 20 to 30 mm, 30 to 40 mm, 40 to 50 mm, and greater than 50 mm (P< 0.001). Multivariate analyses showed that the pathologic T classification and grade of tumor was significantly associated with OS. Tumor length of 30 mm or more remained an independent prognostic factor (P = 0.04), as did the other current TNM factors. Conclusion: Tumor length appears to affect the OS of patients with early-stage esophageal squamous cell carcinoma. It may provide additional prognostic information for the current TNM staging system.

New insights into antigen specific immunotherapy for chronic myeloid leukemia

Chronic myeloid leukemia (CML) is a stem cell disease in which BCR/ABL plays an important role as an oncoprotein and a molecular and immunogenic target. Despite the success of targeted therapy using tyrosine kinase inhibitors (TKIs), CML remains largely incurable, most likely due to the treatment resistance of leukemic stem cells. Several immunotherapies have been developed for CML in different stages and relapse after allogeneic stem cell transplantation. In the this review, several specific immunotherapeutic approaches for CML, including vaccination and adoptive cellular immunotherapy, are discussed along with results from clinical trials, and the value of such immunotherapies in the era of imatinib and leukemia-associated antigens (LAAs), which are capable of inducing specific T cell responses and are appropriate target structures for the immunological targeting of CML cells, are also summarized.

Synchronous adenocarcinomas of the colon presenting as synchronous colocolic intussusceptions in an adult

Intussusception is uncommon in adults. To our knowledge, synchronous colocolic intussusceptions have never been reported in the literature. Here we described the case of a 59-year-old female of synchronous colocolic intussusceptions presenting as acute abdomen that was diagnosed by CT preoperatively. Laparotomy with radical right hemicolectomy and sigmoidectomy was undertaken without reduction of the invagination due to a significant risk of associated malignancy. The final diagnosis was synchronous adenocarcinoma of proximal transverse colon and sigmoid colon without lymph nodes or distant metastasis. The patient had an uneventful recovery. The case also emphasizes the importance of thorough exploration during surgery for bowel invagination since synchronous events may occur.

Urinary metabolomic signature of esophageal cancer and Barrett's esophagus

Background: Esophageal adenocarcinoma (EAC) often presents at a late, incurable stage, and mortality has increased substantially, due to an increase in incidence of EAC arising out of Barrett's esophagus. When diagnosed early, however, the combination of surgery and adjuvant therapies is associated with high cure rates. Metabolomics provides a means for non- invasive screening of early tumor-associated perturbations in cellular metabolism. Methods: Urine samples from patients with esophageal carcinoma (n = 44), Barrett's esophagus (n = 31), and healthy controls (n = 75) were examined using 1H-NMR spectroscopy. Targeted profiling of spectra using Chenomx software permitted quantification of 66 distinct metabolites. Unsupervised (principal component analysis) and supervised (orthogonal partial least-squares discriminant analysis OPLS-DA) multivariate pattern recognition techniques were applied to discriminate between samples using SIMCA-P+ software. Model specificity was also confirmed through comparison with a pancreatic cancer cohort (n = 32). Results: Clear distinctions between esophageal cancer, Barrett's esophagus and healthy controls were noted when OPLS-DA was applied. Model validity was confirmed using two established methods of internal validation, cross-validation and response permutation. Sensitivity and specificity of the multivariate OPLS-DA models were summarized using a receiver operating characteristic curve analysis and revealed excellent predictive power (area under the curve = 0.9810 and 0.9627 for esophageal cancer and Barrett's esophagus, respectively). The metabolite expression profiles of esophageal cancer and pancreatic cancer were also clearly distinguishable with an area under the receiver operating characteristics curve (AUROC) = 0.8954. Conclusions: Urinary metabolomics identified discrete metabolic signatures that clearly distinguished both Barrett's esophagus and esophageal cancer from controls. The metabolite expression profile of esophageal cancer was also discrete from its precursor lesion, Barrett's esophagus. The cancer-specific nature of this profile was confirmed through comparison with pancreatic cancer. These preliminary results suggest that urinary metabolomics may have a future potential role in non-invasive screening in these conditions.

Recognizing and managing the expanded risk of tumor lysis syndrome in hematologic and solid malignancies

Tumor lysis syndrome (TLS) is widely recognized as a serious adverse event associated with the cytotoxic therapies primarily used in hematologic cancers, such as Burkitt lymphoma and acute lymphoblastic leukemia. In recent years, TLS has been more widely observed, due at least in part to the availability of more effective cancer treatments. Moreover, TLS is seen with greater frequency in solid tumors, and particularly in bulky tumors with extensive metastases and tumors with organ or bone marrow involvement. The consequences of TLS include the serious morbidity and high risk of mortality associated with the condition itself. Additionally, TLS may delay or force an alteration in the patient's chemotherapy regimen. The changing patterns of TLS, as well as its frequency, in the clinical setting, result in unnecessarily high rates of illness and/or fatality. Prophylactic measures are widely available for patients at risk of TLS, and are considered highly effective. The present article discusses the various manifestations of TLS, its risk factors and management options to prevent TLS from occurring.

u-PA inhibitor amiloride suppresses peritoneal metastasis in gastric cancer

Background: Peritoneal metastasis in gastric cancer represents a ubiquitous human health problem but effective therapies with limited side effects are still lacking. Although previous research suggested that u-PA was involved in some tumor metastasis such as lung-specific metastasis, the role of u-PA for peritoneal metastasis in gastric cancer is still unclear. The aim of this study was to explore whether selective pharmacological blockade of u-PA is able to affect the peritoneal metastasis of gastric cancer both in vivo and in vitro. Methods: In the present study, we evaluated the effects and explored the anti-tumor mechanisms of amiloride, a selective u-PA inhibitor, on a panel of gastric cancer cell lines and in a murine model of human gastric cancer MKN45. Results: The study showed that amiloride significantly inhibited the tumor growth and prolonged the survival of the tumor-bearing mice. In vitro, compared with controls, amiloride could not only significantly down-regulate the mRNA expression and protein level of u-PA from MKN45 cells with dose dependence but also inhibit the adhesion of HMrSV5 cells, migration and invasion of MKN45 cells. Conclusions: The findings in our current report provide evidence that selective u-PA inhibitor amiloride has potent effects against peritoneal metastasis in gastric cancer, suggesting its possible therapeutic value for the treatment of gastric cancer.

Comparative study comparing endoscopic thyroidectomy using the axillary approach and open thyroidectomy for papillary thyroid microcarcinoma

Background: Endoscopic thyroidectomy has been applied prudently to malignant thyroid tumors. The purpose of our study was to compare the surgical outcomes of endoscopic thyroidectomy (ET) and conventional open thyroidectomy (COT) for micropapillary thyroid carcinoma. Methods: From October 2002 to December 2008, 78 patients underwent unilateral lobectomy and isthmectomy with central lymph node dissection for papillary thyroid microcarcinoma. Of these, 37 patients underwent ET and 41patients COT. Surgical outcomes, including operation time, number of retrieved lymph nodes, postoperative complication rate and patients' satisfaction with the cosmetic results, were analyzed. Results: The mean age of the patients was 42.3 +/- 7.6 years in the ET group and 49.0 +/- 10.8 years in the OT group (P = 0.003). The operation time was shorter in the COT group (112.3 +/- 14min) than in the ET group (138.4 +/- 36.9 min, P< 0.01). However, there were no significant differences in tumor size (0.5 +/- 0.231vs. 0.41 +/- 0.264cm, P = 0.116), number of retrieved lymph nodes (3.63 +/- 2.1vs. 3.82 +/- 3.28, P = 0.78) or postoperative hospital stay (3.35 +/- 0.94vs. 3.17 +/- 1.16 days, P = 0.457). Patients in the ET group experienced more pain than those in the COT group at 1 and 7 days after the operation as evaluated by a visual analog scale (P = 0.037, 0.026). Cosmetically, patients in the ET group were very satisfied with the operative procedure according to the questionnaire we used (1.43 +/- 0.55vs. 3.21 +/- 0.72, P< 0.001). The mean follow-up period was 54.3 months in the ET group and 47.4 months in the COT group, and each group exhibited one case of tumor recurrence detected at the other thyroid lobe within 2 years. Conclusions: Large series of prospective studies and long-term follow-up are needed, but the results of ET using the axillary approach for micropapillary thyroid carcinoma were not inferiortothose using COT, and it might be a safe and feasible procedure with good cosmetic results.

Pulmonary benign metastasizing leiomyoma: a case report and review of the literature

Pulmonary benign metastasizing leiomyoma characterized by the growth of uterine leiomyoma in the lung is a very rare disease. We herein report the case of a 46-year-old asymptomatic woman who underwent a total abdominal hysterectomy for her multiple uterine leiomyomas 5 years ago, with the presence of multiple shadows in her chest roentgenogram during the regular check-up. Chest computerized tomography (CT) showed multiple solitary nodules in both lungs. Video-assisted thoracoscopic surgery with a wedge resection of the lesion was performed. Histopathologically, the pulmonary nodule was composed of benign smooth muscle cells and demonstrated low mitotic activity and absence of necrosis. Immunohistochemical staining for smooth muscle actin (SMA) and Desmin were extremely positive. CD10, CD117 and S-100 were negative in the tumor cells. Positive immunoreactivity for estrogen receptor (ER) and progesterone receptor (PR) were detected. The pathological diagnosis was pulmonary benign metastasizing leiomyoma.

Adjuvant chemotherapy with six cycles of AC regimen versus three cycles of AC regimen followed by three cycles of Paclitaxel in node-positive breast cancer

C Roy, KB Choudhury, M Pal, A Saha, S Bag, C Banerjee



Indian Journal of Cancer 2012 49(3):266-271



Context: Antracycline-Cyclophosphamide (AC) along with Paclitaxel/Docetaxel, either in combination or sequential regimens, is showing superior results than Anthracycline-containing regimens. Aims: This study was designed to determine whether adding Paclitaxel to a standard adjuvant chemotherapy regimen AC for breast cancer patients would prolong the time to recurrence and survival. Settings and Design: Randomized, prospective, open-labeled, single-institutional study. Materials and Methods: Fifty stage II breast cancer patients accruing 25 patients in each arm, treated between July 2007 and January 2010, were included in the study. Initial surgical treatment was Modified Radical Mastectomy. Systemic therapy was to have begun within 4-6 weeks of the patient's surgery. In the control arm, all the patients were treated with six cycles of adjuvant chemotherapy with AC regimen repeated at an interval of 3 weeks. For the study arm, the patients received adjuvant chemotherapy with three cycles of AC regimen followed by three cycles of Paclitaxel, repeated at an interval of 3 weeks. All the patients of both the arms received locoregional external beam radiotherapy (EBRT) after the entire course of chemotherapy. All the hormone receptor-positive patients received Tamoxifen. Statistical Analysis Used: Statistical analysis was performed using the chi-square test and the Kaplan Meier survival analysis with the log-rank (Mantel-Cox) test. Results: Adding Paclitaxel to AC resulted in a statistically significant disease-free survival. The overall survival was also improved significantly. The toxicity profile in both the arms was comparable. Conclusions: In early and node-positive breast cancer, the addition of three cycles of Paclitaxel after completion of three cycles of AC improves the disease-free and overall survival.

Male breast cancer in Indian patients: Is it the same?

SB Chikaraddi, R Krishnappa, V Deshmane



Indian Journal of Cancer 2012 49(3):272-276



Background: Cancer of the male breast accounts for about 1% of all malignancies in men and 1% of all breast cancers. Poor level of awareness often results in late presentation and delayed diagnosis in our environment. This study was done to analyse the demographic data, management and survival of male breast cancers in Indian subset of patients and compare it with that of western literature. Materials and Methods: A 10 year (2001-2010) retrospective study of all male breast cancers was done. Data regarding the incidence, presentation, histopathology, stage and grade of tumor, management and outcome of patients were analysed. Results: 26 cases of male breast cancer were encountered. This comprised 0.4% of all breast cancers seen in our department during the 10 year period. The ages of patients ranged from 45-75 years with a mean age of 57 years. Family history was present in 4 patients. Clinically, symptoms included self-detected lump in 23 (88.5%) patients, nipple retraction in 12 (46.1%) and pain in 12 (46.1%). All cases were unilateral (16 on right, 10 on left). Disease most commonly involved central quadrant (9 patients). Grade 3 disease was found in 13 patients and Stage 3 disease was most commonly encountered (13 patients). None of our patients received neo adjuvant chemotherapy. 20 (76.9%) patients had modified radical mastectomy and 6 (23.1%) had radical mastectomy. Most of our patients were hormone receptor positive (21 patients). Bilateral orchidectomy, Adjuvant chemotherapy, Adjuvant radiotherapy and Tamoxifen were offered in 3 (11.5%), 16 (61.5%), 17 (65.4%) and 15 (57.7%) patients respectively. Follow up ranged from 1-59 months. Conclusion: Male breast cancer is rare in our centre. Late presentation with advanced disease is a common feature in our environment. Further multiinstitutional, prospective studies are needed for better understanding of management of male breast cancers in Indian subset of patients.

Breast cancer management: Past, present and evolving

M Akram, SA Siddiqui



Indian Journal of Cancer 2012 49(3):277-282



Breast cancer is known from ancient time,and the treatment strategy evolved as our understanding of the disease changed with time. In 460 BC Hippocrates described breast cancer as a humoral disease and presently after a lot of studies breast cancer is considered as a local disease with systemic roots. For most of the twentieth century Halsted radical mastectomy was the "established and standardized operation for cancer of the breast in all stages, early or late". New information about tumor biology and its behavior suggested that less radical surgery might be just as effective as the more extensive one. Eventually, with the use of adjuvant therapy likeradiation and systemic therapy, the extent of surgical resection in the breast and axilla got reduced further and led to an era of breast conservation. The radiation treatment of breast cancer has evolved from 2D to 3D Conformal and to accelarated partial breast irradiation, aiming to reduce normal tissue toxicity and overall treatment time. Systemic therapy in the form of hormone therapy, chemotherapy and biological agents is now a well-established modality in treatment of breast cancer. The current perspective of breast cancer management is based on the rapidly evolving and increasingly integrated study on the genetic, molecular , biochemical and cellular basis of disease. The challenge for the future is to take advantage of this knowledge for the prediction of therapeutic outcome and develop therapies and rapidly apply more novel biologic therapeutics.

Indian Journal of Cancer 2012 49(3):283-286



Aims: Imaging-guided biopsies obtain samples for pathologic testing in addition to therapeutic interventions in patients with cancer. Our aim was to determine the diagnostic accuracy of percutaneous biopsies of pediatric solid tumors and infectious complications of cancer treatment. Materials and Methods: This study was performed by gathering pediatric oncology patients between 1998 and 2008. A total of 41 percutaneous biopsies were performed in order to establish a diagnosis for a suspected malignancy or an infectious complication of cancer treatment. Results and Conclusions: An accurate diagnosis was achieved in 21 of 26 (87.6%) percutaneous biopsies for suspected malignancy cases or recurrence. The remaining 15 percutaneous biopsies were done for the diagnosis of infectious complications of cancer treatment with an accurate diagnosis of 60%. Imaging-guided percutaneous biopsy technique is highly accurate and safe, particularly in diagnosis of a suspected tumor.

Posttraumatic growth in Iranian cancer patients

A Rahmani, R Mohammadian, C Ferguson, L Golizadeh, M Zirak, H Chavoshi



Indian Journal of Cancer 2012 49(3):287-292



Objectives: To investigate the level and determinants of posttraumatic growth in Iranian cancer patients. Materials and Methods: This descriptive-correlational design study was conducted within a university-affiliated oncology hospital in Iran. A convenience sample of 450 patients with a definitive diagnosis of cancer of any type completed a demographic questionnaire and a posttraumatic growth inventory. Some disease-related information was obtained from patients' medical records. Results: The mean of posttraumatic growth reported by participants was 76.1. There was a statistically significant association between experience of posttraumatic growth and age (r = &#8722; 0.21, P=0.001), education at university level (F = 8.9, P=0.001) and history of treatment by radiotherapy (t = 2.1, P=0.03). Conclusion: The findings of this study suggest that Iranian cancer patients experience a moderate to high level of posttraumatic growth and confirm the hypothesis that the level of posttraumatic growth in non-Western cancer patients is more than that of Western cancer patients. Although, assessing the reasons for this difference needs more investigations.

Indian Journal of Cancer 2012 49(3):293-297



Context: Pain and palliative care clinic (PCC). Aims: The primary object of this study was to enumerate the demographic characteristics of patients attending a newly organized PCC. The secondary purpose was to detect symptom prevalence and frequency of different cancers in these patients. Settings and Design: Prospective cross-sectional descriptive study. Materials and Methods: A prospective cross-sectional descriptive study was done on patients referred to the PCC of a tertiary hospital in North India. Comprehensive details of all patients were recorded systematically on the first visit on a proforma specially prepared for the newly established palliative care clinic. Statistical Analysis Used: The descriptive statistics of palliative care data was presented in terms of frequencies and percentages (%) for categorical variables. Results: The data collected at our PCC showed that out of 156 patients, 87 were males and 69 were females. Patients of all ages varying from 6 to 85 years were seen. Most patients (82.1%) lived with their families, and 28 (17.1%) patients lived alone and had no financial support. The most common primary diagnoses were head and neck cancers (38.5%), carcinoma cervix (15.4%), breast cancer (10.3%), colorectal cancer (6.4%), and lung cancer (4.5%). Frequency of seven most common symptoms was pain (100%), insomnia (64.1%), loss of appetite (34.6%), nausea (32.7%), vomiting (32.1%), constipation (31.4%) and sore mouth (28.8%). Conclusions: Population-based studies determine the actual magnitude of sufferers and suffering and show that palliative care services should be included as an essential component in a tertiary care hospital. The objective should be to reach out to the patient and help in improving the patent's quality of life in every way possible.

Profile of gynecologic malignancies reported at a tertiary care center in India over the past decade: Comparative evaluation with international data

S Agarwal, KP Malhotra, S Sinha, S Rajaram



Indian Journal of Cancer 2012 49(3):298-302



Objective: Comprehensive statistics on gynecologic malignancies reported from India are deficient. This study was performed to ascertain the profile of gynecologic cancers reported at our center regarding incidence, histologic subtypes, frequency of involvement at various sites and stage at presentation. We endeavored to compare our data with gynecologic cancers reported at other national and international centers. Materials and Methods: Retrospective review of records of gynecologic cancers obtained from Departments of Pathology and Gynecology, at a tertiary care center, Delhi from January 2000 to December 2009 was performed. Comparison with international data was performed using Fishcher's exact test and chi square tests. Results: A total of 1315 gynecologic cancers were reported. Cervical malignancies were the commonest at our center as compared to uterine malignancies in data from Surveillance, Epidemiology, and End Results (SEER) Program of United States and European Union. All malignancies except cervical cancers affected a younger age group at our center than in the US population. Cervical cancer presented at a relatively more advanced stage, ovarian cancers at more localized stages, whereas uterine cancers presented at similar stages as compared to Western data. Conclusions: Our registry presents composite data from North India. Higher age and advanced stage at presentation of cervical cancers suggests lacunae in screening programs available. Ovarian malignancies were more localized at presentation than in the Western population for which environmental or genetic factors may be causative.

Biological behavior and disease pattern of carcinoma gallbladder shown on 64-slice CT scanner: A hospital-based retrospective observational study and our experience

AND Dwivedi, M Pandey, RC Shukla, VK Shukla, S Gaharwar, BN Maurya



Indian Journal of Cancer 2012 49(3):303-308



Purpose: The aim of this diagnostic observational study was to assess the spread and biological behavior of gallbladder cancer using 64-slice computerized tomography (CT) scanner in this particular geographic belt (eastern Uttar Pradesh, western Bihar, and northern Madhya Pradesh provinces of North India). Indians are ethnically and culturally different from their Western counterparts among whom the incidence of this disease is comparatively low. Subjects and Methods: After systemic examination, all patients (87) were subjected to ultrasonographic examination. All cases were histopathologically proven. Confirmed cases were subjected to volumetric CT examination of abdomen and pelvis, plain, post contrast and delayed phase. Results: Majority of the cases were adenocarcinoma. There was female preponderance with majority belonging to fifth and sixth decades. Commonest presentation was diffuse, irregular, enhancing wall thickening in 49.4%. Majority had invasion of liver parenchyma (74.7%). Cholelithiasis was seen in 48.3% cases. Invasion of biliary radicals was high (13.8-18.4%). Eleven cases had invasion of portal vein and tumor thrombus, with hepatic artery invasion in one case. In two cases, both hepatic artery and portal vein invasion was seen. Portal and peripancreatic nodal metastasis was seen in 58.5%. Distant metastasis was reported. Conclusion: Few studies involving the Indian population have attempted to use multi-row detector CT to define the biological behavior of carcinoma gallbladder. The opinion whether the pathology is operable or non-operable can reasonably be given. This large-scale, single-center study gives insight about the epidemiology and biological behavior of carcinoma gallbladder.

Determinants of oxidative stress and DNA damage (8-OhdG) in squamous cell carcinoma of head and neck

A Kumar, MC Pant, HS Singh, S Khandelwal



Indian Journal of Cancer 2012 49(3):309-315



Background: Squamous cell carcinoma of head and neck (SCCHN) is a major concern of health risk in developing countries, such as India. Apart from genetic configuration, environmental and lifestyle factors, as well as poor oral hygiene, provide free radical-generating environment, which may contribute to the development of cancer through DNA damage. Materials and Methods: Here we ascertained the various oxidative stress determinants in diagnosed SCCHN patients with health risk addictions. This study further evaluated the incremental effects inflicted by these lifestyle factors on redox status. The study included 100 consenting SCCHN patients and 90 matched healthy controls. Salivary total antioxidant capacity (TAC), glutathione (GSH), free radicals: such as reactive nitrogen species (RNS) and reactive oxygen species (ROS) along with oxidative DNA adduct (8-OHdG) were monitored. Results: Our findings indicated altered salivary oxidant-antioxidant status in SCCHN. A substantial rise in ROS (~2.0 folds) and RNS (~1.4 folds), together with significant lowering in TAC (~1.2 folds) and GSH (~1.7 folds) was observed. The 8-OHdG levels were also found to be considerably higher (P < 0.001) in salivary cell's DNA of these patients. Conclusions: Our results demonstrate significant redox imbalance in cancer patients suggesting their paramount importance in the development of SCCHN.

C Roy, KB Choudhury, M Pal, A Saha, S Bag, C Banerjee



Indian Journal of Cancer 2012 49(3):266-271



Context: Antracycline-Cyclophosphamide (AC) along with Paclitaxel/Docetaxel, either in combination or sequential regimens, is showing superior results than Anthracycline-containing regimens. Aims: This study was designed to determine whether adding Paclitaxel to a standard adjuvant chemotherapy regimen AC for breast cancer patients would prolong the time to recurrence and survival. Settings and Design: Randomized, prospective, open-labeled, single-institutional study. Materials and Methods: Fifty stage II breast cancer patients accruing 25 patients in each arm, treated between July 2007 and January 2010, were included in the study. Initial surgical treatment was Modified Radical Mastectomy. Systemic therapy was to have begun within 4-6 weeks of the patient's surgery. In the control arm, all the patients were treated with six cycles of adjuvant chemotherapy with AC regimen repeated at an interval of 3 weeks. For the study arm, the patients received adjuvant chemotherapy with three cycles of AC regimen followed by three cycles of Paclitaxel, repeated at an interval of 3 weeks. All the patients of both the arms received locoregional external beam radiotherapy (EBRT) after the entire course of chemotherapy. All the hormone receptor-positive patients received Tamoxifen.

Benefits of intracorporeal gastrointestinal anastomosis following laparoscopic distal gastrectomy

Background: Laparoscopic gastrectomy has recently been gaining popularity as a treatment for cancer; however, little is known about the benefits of intracorporeal (IC) gastrointestinal anastomosis with pure totally laparoscopic distal gastrectomy (LDG) compared with extracorporeal (EC) anastomosis with laparoscopy-assisted distal gastrectomy (LADG). Methods: Between June 2000 and December 2011, we assessed 449 consecutive patients with early-stage gastric cancer who underwent LDG. The patients were classified into three groups according to the method of reconstruction LADG followed by EC hand-sewn anastomosis (LADG + EC) (n = 73), using any of three anastomosis methods (Billroth-I (B-I), Billroth-II (B-II) or Roux-en-Y (R-Y); LDG followed by IC B-I anastomosis (LDG + B-I) (n = 248); or LDG followed by IC R-Y anastomosis (LDG + R-Y) (n = 128)). The analyzed parameters included patient and tumor characteristics, operation details, and post-operative outcomes. Results: The tumor location was significantly more proximal in the LDG + R-Y group than in the LDG + B-I group (P < 0.01). Mean operation time, intra-operative blood loss, and the length of post-operative hospital stay were all shortest in the LDG + B-I group (P < 0.05). Regarding post-operative morbidities, anastomosis-related complications occurred significantly less frequently in with the LDG + B-I group than in the LADG + EC group (P < 0.01), whereas there were no differences in the other parameters of patients' characteristics. Conclusions: Intracorporeal mechanical anastomosis by either the B-I or R-Y method following LDG has several advantages over at the LADG + EC, including small wound size, reduced invasiveness, and safe anastomosis. Although additional randomized control studies are warranted to confirm these findings, we consider that pure LDG is a useful technique for patients with early gastric cancer.

Prognostic value of expression of molecular markers in adenoid cystic cancer of the salivary glands compared with lymph node metastasis: a retrospective study

Background: Adenoid cystic cancer arising in the salivary glands has distinctive features such as perineural invasion, distant metastasis, and a variable prognosis. In salivary gland cancer, c-kit, EGFR, and VEGF are representative molecular markers that may predict remnant and recurrent tumors. In this study, the expression of c-kit, EGFR, and VEGF in adenoid cystic cancer was evaluated, and the relationships between the expression of these markers and the clinical findings were investigated. Methods: The medical records of 48 patients who were treated for parotid adenoid cystic cancer from January 1990 to January 2006 were reviewed. The tumor location, size, histological subtypes, perineural invasion, the resected margin status, and lymph node metastasis were assessed. Immunohistochemical staining and semiquantitative analysis of c-kit, EGFR and VEGF were performed. The relationship between the expression of each marker and the clinicopathological factors were analyzed. Results: Positive c-kit immunostaining was present in 45 patients (94%), with weak positivity (+1) in 23, moderate positivity (+2) in 19 and strong positivity (+3) in three. Positive EGFR immunostaining was observed in 27 (56%), with weak positivity (+1) in 19 and moderate positivity (+2) in eight with no strong positive staining. Positive VEGF immunostaining was present in 42 patients (88%) with weak positivity (+1) in 12, moderate positivity (+2) in 17, and strong positivity (+3) in 13. Only the expression of VEGF was significantly higher in parotid gland tumors than in any other gland (P = 0.032). Marginal involvement was associated with strong VEGF expression (P = 0.02). No marker was significantly correlated with recurrence or the survival rate. Lymph node status was related to the survival rate. Conclusions: The expression of c-kit, EGRF, and VEGF had no predictive value for recurrence or the prognosis of adenoid cystic cancer. Only the lymph node status was related to the prognosis.

Sleeve lobectomy versus pneumonectomy for non-small cell lung cancer: a meta-analysis

Aim: It is controversial that whether sleeve lobectomy(SL) should be promoted more worthy than pneumonectomy (PN) in suitable patients. Methods: We searched all studies that had been published in English from PUBMED and Embase which compared the short-term and long-term outcomes of SL and pneumonectomy(PN) in patients with non-small cell lung cancer (NSCLC). Results: Nineteen studies met our criteria with a combined total of 3878 subjects, of which 1316 (33.9%) underwent SL and 2562 (66.1%) underwent PN. The odds ratio was 0.50 (95%CI: 0.34-0.72) for postoperative mortality, 1.17 (95% CI: 0.82-1.67) for postoperative complications, 0.78 (95% CI: 0.47-1.29) for locoregional recurrences. The risk difference for 1-, 3-, 5- year was 0.11 (95% CI: 0.07-0.14), 0.15(95% CI: 0.06-0.24), 0.15(95% CI: 0.09-0.20),respectively. The pooled hazard ratio was 0.63 (95%CI: 0.56-0.71) in favor of SL group. Conclusion: SL is more worthy to be done than PN in suitable patients with less mortality and better long-term survival.

MSH2 and CXCR4 involvement in malignant VIPoma

Background: Vasoactive intestinal polypeptide secreting tumors(VIPomas) are rare endocrine tumors of the pancreas with an estimated incidence of 0.1 per million per year. The molecular mechanisms that mediate development of VIPomas are poorly investigated and require definition. Methods: A genome- and gene expression analysis of specimens of a primary pancreatic VIPoma with hepatic metastases was performed. The primary tumor, the metastases, the corresponding healthy tissue of the liver, and the pancreas were compared with each other using oligonucleotide microarrays and loss of heterozygosity (LOH). Results: The results revealed multiple LOH events and several differentially expressed genes. Our finding of LOH and downregulation was conspicuous in the microarray analysis for the mismatch repair gene MSH2 in the primary pancreatic VIPoma tumor, the hepatic metastasis but not in the corresponding healthy tissue. Further a strong overexpression of the chemokine CXCR4 was detected in the hepatic metastases compared to its pancreatic primary. With a review of the literature we describe the molecular insights of metastatic development in VIPoma. Conclusion: In VIPoma, defects in the mismatch repair system especially in MSH2 may contribute to carcinogenesis, and increased CXCR4 may be associated with liver metastasis.

Alternative expression of TCRzeta related genes in patients with chronic myeloid leukemia

A previous study has demonstrated a significant decrease in the TCRzeta gene expression level in chronic myeloid leukemia (CML); thus, we further investigated the expression of TCRzeta-regulating factors, the distribution of the TCRzeta 3' untranslated region (3'-UTR) splice variants, and the expression level and correlation of the alternative splicing factor/splicing factor 2 (ASF/SF-2), FcepsilonRIgamma and ZAP-70 genes. TCRzeta 3'-UTR splice variants were identified in peripheral blood mononuclear cells (PBMCs) from 14 healthy individuals, 40 patients with CML and 22 patients with CML in complete remission (CML-CR) by RT-PCR. The expression level of the TCRzeta, FcepsilonRIgamma, ASF/SF-2 and ZAP-70 genes was analyzed by real-time quantitative PCR. While the expression of TCRzeta gene in the CML group was significantly lower than that in the healthy individual and CML-CR groups, a significantly higher expression of the FceRIgamma and ASF/SF-2 genes was found in the CML group. Two types of splicing forms were detected in all of the healthy individual CML-CR cases: wild type (WT) TCRzeta 3'-UTR and alternatively splieced (AS) TCRzeta 3'-UTR which have been alternatively splieced in the WT TCRzeta 3'-UTR . However, 35% of the CML cases contained only the wild type TCRzeta 3'-UTR isoform. Based on the TCRzeta 3'-UTR isoform expression characteristic, we divided the patients with CML into two subgroups: the WT+AS- CML group, containing patients that express only the wild type TCRzeta 3'-UTR, and the WT+AS+ CML group, which contained patients that expressed two TCRzeta 3'-UTR isoforms. A significantly different ASF/SF-2 and FcepsilonRIgamma gene expression pattern was found between the WT+AS- and WT+AS+CML groups. We concluded that defective TCRzeta expression may be characterized in the WT+AS-and WT+AS+CML subgroups by the different gene expression pattern. The overexpression of ASF/SF2, which alternatively splices the TCRzeta [unknown]3'-UTR, is thought to participate in feedback regulation. The characteristics of TCRzeta 3'-UTR alternative splicing may be a novel immunological marker for the evaluation of the CML immune status.

A novel monoclonal antibody of human stem cell factor inhibits umbilical cord blood stem cell ex vivo expansion

Stem cell factor (SCF) activates hematopoietic stem cell (HSC) self-renewal and is being used to stimulate the ex vivo expansion of HSCs. The mechanism by which SCF supports expansion of HSCs remains poorly understood. In cord blood ex vivo expansion assays, a newly produced anti-SCF monoclonal antibody (clone 23C8) was found to significantly inhibit the expansion of CD34+ cells. This antibody appears to bind directly to a part of SCF that is critical for biological activity toward expansion of CD34+ cells, which is located in the first 104 amino acids from the NH2-terminus.

Targeted cellular ionic calcium chelation by oxalates: Implications for the treatment of tumor cells

Background: In malignant melanoma, it has been published that up to 40 % of cancer patients will suffer from brain metastasis. The prognosis for these patients is poor, with a life expectancy of 4 to 6 months. Calcium exchange is involved in numerous cell functions. Recently, three types of cellular calcium sequestration have been reported in the medical literature. The first describes a transgenic mouse model in which an increase of aberrant calcium channels triggers hypertrophy and apoptosis. The second provides a protective mechanism whereby astrocytes in the brain inhibit apoptosis of tumor cells by moving ionic calcium out of the tumor cells thru gap junctions. The third is via calcium chelation, which causes cell apoptosis by converting ionic calcium into a calcium salt. This process has been shown to operate in atrial myocardial cells, thus not allowing the intracellular calcium stores to flow through the myocytes intercalated discs. Ideally chemotherapeutic agents would be those that initiate apoptosis in tumor cells.Presentation of the hypothesisWe hypothesize that the recent reported intracellular calcium sequestration by oxalate chelation, due to its chemical process of converting ionic calcium into a calcium salt, may inhibit the protective effect of astrocytes on brain tumor metastasized melanoma cells by not allowing free calcium to leave the metastatic cells, simultaneously apoptosis of tumor and some healthy adjacent cells could occur. This hypothesis could be extended to include other cancerous tumors such as skin cancers amongst others.Testing the hypothesisUsing the experimental model showing the protective mechanism of co-cultured reactive astrocytes and tumor cells treated with oxalates could be used to test this hypothesis in vitro. The calcium specific von Kossa technique could be used to confirm the presence of chelated intracellular calcium architecture of the metastatic cells (which is a sign of apoptosis), and extracellular calcium chelation stores of the Astrocytes (which has been shown to slow neural conduction).Implications of the hypothesisThe life expectancy in patients with metastasized malignant melanoma brain tumors could be significantly prolonged if the chemotherapeutic issue of brain metastasis is overcome. Other cancerous tumors can also be treated by this Targeted Chelation Approach. Ionic calcium sequestration using naturally occurring calcium chelators, viz., oxalates, could accomplish this desired outcome.

Different distribution of breast ductal carcinoma in situ, ductal carcinoma in situ with microinvasion, and invasion breast cancer

Background: Breast ductal cancer in situ (DCIS) can recur or progress to invasive ductal cancer (IDC), and the interim stage include DCIS with microinvasion (DCIS-Mi). In this article, we attempt to study the study the differences of clinicopathological features, imaging data, and immunohistochemical-based subtypes among DCIS, DCIS-Mi, and IDC. Methods: In this retrospective study, we attempt to compare the clinicopathological features, immunohistochemical results and imaging data of 866 patients (included 73 DCIS, 72 DCIS-Mi, and 721 IDC). Results: Patients with DCIS and DCIS-Mi were younger than those with IDC (P = 0.007). DCIS and DCIS-Mi often happened in premenopausal women while IDC was opposite (P <0.001). The incidence of IDC with node-positive was significantly higher than it in DCIS and DCIS-Mi (P <0.001). We also observed that the Her2-positive was more often found in patients with pure DCIS compared to those with DCIS-Mi and DCIS-I (P <0.001). There was a significant difference between the four subgroups (Luminal-A, Luminal-B, ERBB2+, Basal-like) from DCIS, DCIS-Mi, and IDC (P <0.001). Basal-like patients were fewer than other subgroups in DCIS, DCIS-Mi, and IDC. The incidence of the first performance of ultrasound (catheter winded and nodular mass) and mammography (nodular mass) had significantly difference among patients with DCIS, DCIS-Mi, and IDC (P <0.001). Conclusions: Different clinicopathological, immunohistochemical, and imaging features among DCIS, DCIS-Mi, and IDC indicate that they are distinct entities. A larger sample size is needed for further study.

Adult primary retroperitoneal cavernous hemangioma: a case report

Primary retroperitoneal cavernous hemangioma (PRCH) in an adult is extremely rare. We report on the diagnosis and treatment of a patient with PRCH with subtle clinical features and atypical findings on imaging scans. A 38-year-old man was admitted to hospital with a 5-day history of epigastralgia after alcohol drinking. Using various imaging methods, we found a giant cyst-like retroperitoneal mass compressing the surrounding organs. Surgical resection of the tumor was performed, and the mass was found to be a cavernous hemangioma measuring 90 x 80 x 60 mm, with a thick fibrotic wall and extensive intracystic hemorrhage. Physicians should be aware that PRCH may mimic a cystic neoplasm, and that a large tumor size probably indicates intracystic hemorrhage. Surgical resection is a curative approach for PRCH.

SU11652 Inhibits tyrosine kinase activity of FLT3 and growth of MV-4-11 cells

Background: FLT3-ITD and FLT3-TKD mutations are frequently found in acute myeloid leukemia(AML). This makes tyrosine kinase FLT3 a highly attractive target for therapeutic drugdevelopment. However, effective drugs have not yet emerged. This study is intended toidentify and to characterize new FLT3 inhibitors. Methods: By using the protein substrate GST-FLT3S to analyze kinase activity of recombinant proteinscarrying the catalytic domain of wild type and mutant forms of FLT3, we screened achemical library containing 80 known protein kinase inhibitors. We identified SU11652 as apotent FLT3 inhibitor and further employed FLT3-ITD-positive MV- 4-11 cells to study itseffects on cell growth, apoptosis, cell cycles, and cell signaling. Results: SU11652 strongly inhibited the activity of wild type, D835Y, and D835H mutant forms ofFLT3 with IC50 values of 1.5, 16, and 32 nM, respectively. It effectively blocked the growthof FLT3-ITD -positive MV-4-11 cells at nanomolar concentrations but exhibited much lesseffects on several other cells which do not carry mutations of FLT3. SU11652 inhibitedgrowth of MV-4-11 cells by inducing apoptosis, causing cell cycle arrest, and blockingactivation of the ERK, Akt, and STAT signaling pathways. Conclusion: SU11652 is a potent FLT3 inhibitor which selectively targets FLT3-ITD-positive cells. Itshould serve as a good candidate for development of therapeutic drugs to treat AML.

A case of parosteal osteosarcoma with a rare complication of myositis ossificans

We report the case of a parosteal osteosarcoma of the distal ulna, treated with wide resection without reconstruction. The patient developed lung metastasis and a mass in the interosseus membrane of the forearm proximally to the osteotomy. The lung mass was found to be a metastasis from parosteal osteosarcoma and the biopsy of the forearm mass revealed a myositis ossificans. The suspicion of a recurrence of parosteal osteosarcoma, already metastatic, led to a second wide resection with no reconstruction. A slice of the radial cortex was taken during this second procedure. From a histological point of view, good margins were achieved and diagnosis of myositis ossificans was confirmed. Two months later, a radius fracture occurred and a synthesis, with plate and screws, as added with poly(methyl methacrylate) (PMMA) to reconstruct the bone loss, was performed. Indication of the reconstructive technique and the complication after distal ulna resection in oncologic surgery are discussed in this paper.

Skin-sparing mastectomy and immediate latissimus dorsi flap reconstruction: a retrospective analysis of the surgical and patient-reported outcomes

Background: Skin-sparing mastectomy (SSM) and latissimus dorsi (LD) flap immediate breast reconstruction (IBR) is a tailored surgical procedure. The surgical and patient-reported outcome (PRO) of SSM and LD IBR were assessed. Methods: Retrospective data of 146 SSMs performed by a single surgeon was reviewed. Among patients included in the data, 65 patients underwent SSM and LD IBR without a prosthetic implant. A survey estimating the degree of patient satisfaction (poor, fair, good, and excellent) as regards the cosmetic outcomes of surgery was performed. The patients were divided into two groups according to their degree of satisfaction (excellent group versus non- excellent group), and analysis was done to identify factors affecting the highest patient satisfaction. Results: The mean age of the patients was 48.4 years, and pathological results were: infiltrating ductal carcinoma (n = 48, 73.8%), ductal carcinoma in situ (n = 15, 23.1%), and others (n = 2, 3.1%). One patient received postmastectomy radiotherapy. After a mean follow-up of 34 months, no local recurrence occurred. There was no skin necrosis or LD flap loss. Donor site morbidities were seroma (n = 8, 12.3%), scarring (n = 8, 12.3%), and back pain (n = 6, 9.2%). Fifty patients (76.9%) were satisfied and 40% reported their degree of satisfaction as excellent. Breast symmetry (P <0.001), nipple cosmesis (P <0.001), visual difference of bilateral breasts (P = 0.021), and panel assessment score (P <0.001) were factors that affected the highest patient satisfaction. Conclusions: Our SSM and LD IBR was safe, with no local recurrence and low morbidities, and produced a sufficiently high level of patient satisfaction. Achieving breast symmetry and nipple cosmesis would be the key to meeting the patient's expectation.
