Quiz: Introduction to UGI Cancer

  1. The American Cancer Society estimates, during 2003, approximately 13,900 new esophageal cancer cases will be diagnosed in the world.
  2. Esophageal cancer is more common among men than among women; the disease is also more common among African Americans than among whites.
  3. Most of stomach cancers are adenocarcinomas, arising in the glandular cells in the stomach lining.
  4. The majority of malignant neoplasms of the small intestine are carcinoid tumors and commonly start in the ileum.
  5. One of the risk factors for esophageal cancer is Barrett esophagus -- the extension of glandular stomach epithelium more than 3 cm into small intestine.
  6. While duodenal ulcer may have some increased risk for stomach cancer, benign gastric ulcers have a low tendency to become malignant.
  7. Early symptoms of esophageal, stomach, and small intestine cancers tend to be vague and nonspecific. In many cases, the cancer has spread before it is found.
  8. Esophageal cancer is lethal because the esophagus has no serosa; any tumor extension beyond the esophagus can spread rapidly.
