Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Background: * Gastric (stomach) cancer is a rare cancer. In most cases, by the time it has been diagnosed it has spread to other organs in the body and the chance of a cure is very small. The standard treatment for gastric cancer is a combination of chemotherapy drugs. * Researchers are interested in finding out if surgically removing all tumors before beginning chemotherapy for stomach cancer can slow or halt its spread better than giving chemotherapy alone. Objectives: \- To determine whether tumor removal surgery followed by chemotherapy is more effective in treating gastric cancer than chemotherapy given alone. Eligibility: \- Patients 18 years of age and older who have been diagnosed with gastric cancer. Design: * All patients will undergo an initial physical examination, blood tests, imaging scans, and a laparoscopy to determine the extent of the disease. * Half of the participants will be assigned to have surgery first and then chemotherapy; the other half will be assigned to have chemotherapy alone. * The surgery-plus-chemotherapy group will have major surgery to remove all tumors in the stomach and abdominal area, followed by a recovery time of up to 4 weeks. Chemotherapy will begin 6 to 8 weeks after surgery. * The chemotherapy-only group will begin treatment within 2 weeks of laparoscopy. * All patients will receive four chemotherapy drugs: 5-Fluorouracil, leucovorin, oxaliplatin, and irinotecan. The drugs are given intravenously over 2 days every 2 weeks (one cycle) for 12 cycles (about 6 months), either at the National Institutes of Health (NIH) Clinical Center or at home with a referring oncologist. Patients in the surgery group who have tumors in the peritoneum will receive an additional set of chemotherapy drugs in a separate treatment. * During the chemotherapy cycles, patients will provide blood samples approximately once a week and will have physical examinations and scans on a regular basis. * Patients will return to the NIH Clinical Center for follow-up visits about every 4 months for 2 years, then every 6 months for 3 years and yearly thereafter.
