[Treatment of primary gastric non-Hodgkin's lymphoma]

Fifty-five patients with primary gastric non-Hodgkin's lymphoma were treated in our hospital from 1970 to 1986. The overall 5-year survival rate was 70.5%. For patients with Stages IE and IIE, the 5-year survival rates were 90.5% and 57.1%, respectively. No significant relation to survival was observed concerning sex, age and course of disease. The important prognostic factors of primary gastric non-Hodgkin's lymphoma were: stage, histologic type, depth of invasion and mode of management. Postoperative radiation therapy with or without chemotherapy was better than surgery alone. Total 60Co abdominal irradiation by moving strip technique was better than multifield irradiation. While no evidence was in favor of post-operative radiotherapy plus chemotherapy for stage IE and IIE lesions, multi-disciplinary approach should be considered for patients at high risk of recurrence and metastasis.
