SUMMARY Background Small bowel adenocarcinoma is a rare cancer and consequently the options for clinical

considering the structure of appendix,its great blood supply and lymphatic tissue,and its anatomical location it seems to have an immunologic role.there are no clear studies regarding the relation between appendectomy and cancer of digestive system.therefore,this stuty proposed for to clarify the relation between previous appendectomy and present gastrointestinal (GI)adenocarcinoma.the cancer g...

Alpha-fetoprotein (AFP) is a plasma protein that is produced by the liver and the yolk sac during fetal development. In adults, an elevation in this protein can be exclusive to specific malignancies such as hepatocellular carcinoma, yolk sac tumors, and metastatic disease to the liver. In the clinical setting, an elevated AFP level and a liver mass (masses) translate to a diagnosis of hepatocel...

INTRODUCTION Surgical resection is the only curative treatment for gastric cancer. However, the overall prognosis of gastric adenocarcinoma is poor and advanced disease may even make surgical treatment impossible. It has been theoretically proposed that administration of chemotherapy before surgical resection may down-stage the disease state and facilitate resectability especially in locally-ad...

BACKGROUND Hepatoid adenocarcinoma (HAC) is a peculiar type of extrahepatic adenocarcinoma generally characterized by adenocarcinomatous and hepatocellular carcinoma (HCC)-like foci. Stomach is the most frequent site where hepatoid adenocarcinoma occurs, although it has been described in many other organs. On the other side, liposarcoma is a rare, malignant tumor that develops from fat cells. ...

BACKGROUND In previous reports concerning the association between sex disparity and age, gastric cancer (GC) patients were simply divided into younger and older groups by age. We analyzed the age trend of the male to female sex ratio (MFSR) in GC based on patient sequential age in order to observe the changing process of MFSR with age. METHODS One thousand seven hundred fifty-one surgical gas...

BACKGROUND Cancer may follow exposure to an environmental agent after many decades. The bacterium Helicobacter pylori, known to be acquired early in life, increases risk for gastric adenocarcinoma, but other factors are also important. In this study, we considered whether early-life family structure affects the risk of later developing gastric cancer among H. pylori+ men. METHODS AND FINDINGS...

Gastric adenocarcinoma is a rare entity in the pediatric population. Gastric hepatoid adenocarcinoma with elevated serum alpha-fetoprotein (AFP) is seen extremely rarely in children. A 12-year-old boy was admitted to the hospital with complaint of abdominal pain. X-ray revealed free air density below the diaphragm. Emergent laparotomy showed perforated stomach. Four weeks after the operation, h...

Among 121 cases of primary gastric malignant lymphoma from 1962 to 1994 at the National Cancer Center Hospital, Tokyo, we found four cases (three males and one female) of adenocarcinoma coexisting in the stomach. The incidence of gastric malignant lymphoma together with gastric adenocarcinoma was 3.3%, suggesting that patients with lymphoma may have an increased incidence of gastric adenocarcin...
