 To evaluate the influence of therapeutic methods on the prognosis of primary gastric B-cell lymphoma, we analyzed the prognostic factors for 322 patients, comprised of 186 with low-grade MALT lymphoma,54 with diffuse large B-cell lymphoma (DLBL)plus MALT lymphoma, and 82 with DLBL without MALT lymphoma. Among them, the clinical course of 96 patients who were treated by Helicobacter pylori eradication was also evaluated. Patients who underwent stomach-conserving treatment(H. pylori eradication, chemotherapy or radiation ; n=100)showed a better overall survival probability than those treated by surgery(n=222), but the progression-free probability did not differ between the two groups. After H. pylori eradication, complete remission was achieved in 55 patients, of whom histologic relapse was observed in 4 patients(7 %). Second line treatment for 34 patients, who failed to respond to eradication therapy, including oral monochemotherapy with cyclophosphamide, radiation,CHOP chemotherapy, and gastrectomy resulted in complete remission in 29 patients(85 %). These results suggest stomach-conserving treatment to be an optimal therapeutic modality for primary gastric B-cell lymphoma.
