Abstract
197 cases of gastric lymphoma were reported to a population-based Danish registry of non-Hodgkin's lymphomas. 106 of these cases were localized, representing stages IE and II1E, and were analyzed retrospectively, using Cox regression analysis. 67 had surgical resection, 51 chemotherapy, and 55 radiotherapy, or combinations thereof. No type of treatment showed any superiority as regards survival (p = 0.13). Overall 5-year survival was 67%. The pretherapeutic presence of fever or S-LDH-elevation had a far more significant influence on survival than histology or any of the treatments or treatment combinations. Surgical resection was associated with a significantly higher risk of late complications than radiotherapy, suggesting that radiotherapy may be preferable to surgery as the primary treatment in localized gastric lymphoma. It could not be determined from the available data whether the addition of chemotherapy to the primary treatment provides any survival benefit.
