Background and Aim: Gastric cancer is the second most common cancer worldwide. In this study the clinical and histological features of gastric cancer in the cardia and distal stomach were evaluated. Method: Proximal and distal gastric cancer diagnosed and treated in eight provinces of Iran from 2010-2011 were reviewed in all collected cases. The age standardized incident rates were calculated and tumor location and histological type were recorded. Results: The age-standardized incidence rate for the eight centers was 40.6 per 100,000 populations per year with an upper and lower range of 22.1 and 102.4 per 100,000 population per year. Thirty four percent of the tumors were located in the cardia, 3% in fundus, and 63% in the distal stomach. In 7 provinces the prevalence of distal tumors was significantly greater than proximal tumors (p=0.006). A significant relationship was observed between diffuse form of gastric cancer and distal gastric tumors (p=0.007) and between poor tumor differentiation and distal gastric tumors (p<0.001). Conclusions: the result of this study shows that distal gastric cancer is more common than proximal gastric cancer in Iran.

Background and Aim: Cholangiocarcinoma (CCA) is an uncommon malignancy of the bile duct, occurring in nearly 2 out of 100,000 people. It is a type of adenocarcinoma that originates in the mucous glands of the epithelium, or surface layers of the bile ducts. The aim of this study was to evaluate the clinical features, diagnostic results and factors associated with survival, morbidity and mortalityof cholangiocarcinoma cases in Iranian patients. Method: In this retrospective study the hospital medical records of 283 patients with a primary or final diagnosis of cholangiocarcinoma who had been admitted to gastroenterology ward of our hospital from 2004 to 2011 were retrospectively reviewed. Results: 283 patients (180 male, 63%, and 103 female, 38.6%) with a mean age of $59.7{\pm}14.4$ years were studied. The most frequent symptoms were painless jaundice (190, 66.9%), abdominal pain (77, 27%), pruritus 133 (46.8%) and weight loss (169, 59.5%). The most frequent associated risk factors and diseases were as follows: gallstones (72, 25.4%), diabetes (70, 24.6%), HBV infection (52 (18.3%), HCV infection 43 (15%), primary sclerosing cholangitis (16, 5.6%) and smoking (120, 42.3%). The most frequent type of cholangiocarcinoma in ERCP and MRCP was hilar. The mean survival time was $7.42{\pm}5.76$ months. Conclusion: The mean survival time in our study was lower than one year. Moreover the most frequent risk factors and associated diseases were smoking, gallstones and diabetes. Painless jaundice, abdominal pain and weight loss were the most clinical features related to cholangiocarcinoma. Additionally survival time did not correlate with risk factors, associated diseases and clinical presentations, but was linked to biliary metallic stenting and surgery.
