DEAR EDITOR, Peri-ampullary and pancreatic head cancer can cause significant morbidity and mortality among gastrointestinal malignancies in human beings because of its important anatomy and physiology. This tumor is responsible for about 150,000 deaths annually all over the world, and is categorized as the 5 leading causes of death among the malignancies. [2] Pancreaticoduodenectomy (PD) is the...
PURPOSE The genetic alterations in biliary tract cancer and clinicopathological associations have not been studied in large population-based studies. EXPERIMENTAL DESIGN We evaluated genetic alterations such as K-ras mutation, p53 overexpression, microsatellite instability (MSI), and alterations of the polyadenine tract present in the transforming growth factor beta receptor type II (TGFbetaR...
The identification of circulating tumor antigens or their related autoantibodies provides a means for early cancer diagnosis as well as leads for therapy. We have used a proteomic approach to identify proteins that commonly induce a humoral response in pancreatic cancer. Aliquots of solubilized proteins from a pancreatic cancer cell line (Panc-1) were subjected to two-dimensional PAGE, followed...
Non-ampullary duodenal adenoma with activation of Wnt/β-catenin signalling is common in familial adenomatous polyposis (FAP) patients, whereas sporadic non-ampullary adenoma is uncommon. The adenoma-carcinoma sequence similar to colon cancer is associated with duodenal tumors in FAP, but not always in sporadic tumors. We obtained 37 non-ampullary duodenal tumors, including 25 adenomas and 12 ad...
Introduction: Duodenal gangliocytic paraganglioma (DGP) is a benign tumor that only warrants surgical resection in the majority of cases. Case Report: We are reporting case 42-year-old man who consulted for significant weight loss, fatigue, anemia, and an on–off obstructive jaundice. Imageries showed 5 cm peri-ampullary duodenal mass. couldn’t have diagnosis by endoscopic ultrasound (EUS), so w...
Ampullary carcinomas are rare malignancies representing less than 1% of all gastrointestinal cancers. Given the low incidence rate, there is scarcity of data regarding the survival benefit of the treatment options available. In the 2014 ASCO Gastrointestinal Cancers Symposium there were two abstracts that discussed the role of pancreaticoduodenectomy and adjuvant radiation therapy in ampullary ...
Endoscopic papillectomy has been reported to be the treatment of choice in patients with ampullary adenoma. For ampullary cancer, pancreaticoduodenectomy is the standard treatment. Since neither lymphatic permeation, vascular invasion, nor lymph node metastasis is observed in patients with ampullary cancer limited to the mucosa, endoscopic resection of such tumors can be justified if no ductal ...
