Gastric lymphoma in stage I or II was usually treated by partial gastrectomy and total abdominal irradiation in our institute since 1970. Since 1978, a number of patients were also treated without laparotomy, in clinical stage I with radiotherapy only and in clinical stage II with combined modality treatment. Treatment results of 58 patients are reported. A relapse-free survival rate of 85% was reached for 24 patients treated with resection and irradiation either in stage I or II, and for seven patients in stage I who did not undergo surgery. For these patients, survival in stage I was 85%, in stage II, however, survival dropped to 60% due to intercurrent deaths. Seven stage II2 patients received intensive chemotherapy and radiotherapy with 58% relapse-free survival. Twenty patients could not be treated according to the outlined treatment protocol. For the total group, survival in stage I is 65% and in stage II 35%. In the Addendum, an additional group of 17 patients is mentioned with the same result.
