BACKGROUND Expression of the dimeric M2 isoenzyme of pyruvate kinase, termed Tumor M2-PK, is increased in some human cancers. This study evaluates the potential role of pre-operative Tumor M2-PK as a marker of prognosis in patients with pancreatic malignancy. METHODS Seventy-three consecutive patients with a clinical diagnosis of pancreatic or peri-ampullary cancer were enrolled. Their median...

Papillotubular adenoma of the ampullary region in a rare tumor which has the potential for malignant transformation. Although reported more frequently nowadays, ampullary tumors are difficult to diagnose before operation unless they cause obstructive jaundice. Occasionally they are detected by ultrasonography, computed tomography or ERCP in patients who complain of nonspecific upper abdominal d...

Introduction. Carcinoid tumors are low-grade tumors originating from endoderm and mostly involving the gastrointestinal system. However; they may be seen in any site within the gastrointestinal system. Case Presentation. A 69-year-old female patient. The results of blood tests were observed to be consistent with obstructive jaundice. A mass appearance was not encountered on tomographic examinat...

diagnosis of ampullary tumors during screening en-doscopy or radiological imaging studies is increasing. Traditional management for ampullary tumors is surgical resec-tion. However, surgical intervention needs radical excision, including excision of the surrounding organs around the am-pulla of Vater. With the development of endoscopic techniques , endoscopic resection for ampullary tumors has ...

Biliopancreatic tumors that are potentially amenable to local resection include proximal bile duct tumors (Klatskin tumors), midcholedochal duct tumors and tumors arising from the papilla of Vater. This paper reviews our experience in the AMC, with local resection of these conditions. From 1983-1997, 112 patients underwent surgical resection of a carcinoma of the hepatic duct sonfluence (Klatsk...
