The role of surgery in the management of gastric lymphoma.
With the development of more effective combination chemotherapy and radiation, the role of surgical resection in the management of gastric lymphoma is reappraised. A retrospective review of 32 patients with gastric lymphoma, diagnosed and treated during the period between 1966-1979, is presented in an attempt to evaluate the relative effectiveness of the various modalities of diagnosis and treatment. Preoperative gastric barium x-ray studies were abnormal in 28 patients but were infrequently diagnostic of lymphoma. Endoscopy was employed in 15 patients with washings and biopsy. The biopsies were reported: four nondiagnostic; three suspicious of tumor; three carcinomas; and in only five patients was a clear diagnosis of lymphoma established. Fifteen patients were treated on the basis of biopsy via gastroscopy, or were explored and not resected and were treated with chemotherapy and/or radiation therapy. Fourteen of the nonresected patients have died with disease; one patient is surviving with disease at 20 months. Surgical resection was accomplished in 17 of the 32 cases, with seven patients (41%) surviving from 2-12 years. Aggressive primary chemotherapy with four-drug combination (CAOP) without surgical resection has resulted in massive upper gastrointestinal hemorrhage in four of five patients thus treated. This required emergency surgery for patients with depressed leukocyte and platelet counts. No perforation of the stomach was seen with primary chemotherapy as reported by other authors. In this series surgical exploration was necessary to establish a definite histologic diagnosis in 27 of the 32 patients. Exploration was an essential step in establishing the extent of disease to plan therapy. The only long-term survivors free of tumor were those which had been surgically resected. Resection of the gastric lymphoma prevented the complication of hemorrhage and perforation associated with chemotherapy and radiation therapy.
