Gastric Cancer

Adenocarcinoma of the stomach is a common malignancy of the digestive tract worldwide. It occurs most frequently in men over 40 years old. Diagnosis is often delayed by the absence of symptoms in early disease or by self-treatment of symptoms, some of which are common to other, less serious gastrointestinal disorders (bloating, gas, and a sense of fullness). Risk factors for gastric cancer are a family history of gastric cancer, Helicobacter pylori infection, blood type A, a personal history of pernicious anaemia, a history of chronic atrophic gastritis, a condition of decreased gastric acid, and a prior history of adenomatous gastric polyp. Most of gastric carcinomas are adenocarcinomas. Majority are situated in the prepyloric region. There are three morphological forms - fungating tumours, malignant ulcers and infiltrating carcinoma. Partial or total gastrectomy is the only curative treatment.
