Primary gastric lymphoma represents 1 to 6% of all gastric cancer and anatomically is the most common type of extranodal lymphoma. We present the clinicopathologic findings in 9 patients with primary gastric lymphoma between Jaunary 1984 and March 1990 in the this hospital. 1) The mean age of patients was 46.0 years with a male to female ratio 3.5:l. 2) The most common initial symptom was epigastric pain among these patients. 3) Fiberoptic gastroscopy was performed in 9 patients, who revealed ulceroinfiltrative lesion in 4 cases, ulcerative lesion in 3 cases, infiltrative lesion in 2 cases, respectively. Pathologic findings of biopsy specimens elicited gastric lymphoma in 8 cases and adenocarcinom in 1 case respectively. 4) All were non-Hodgkins lymphoma, and histologic classification by the Rappaport system was possible in all cases including 4 cases of diffuse histiocytic type, 3 cases of diffuse mixed histiocytic and lymphocytic, 2 cases of diffuse lymphocytic poorly differeatiated type respectively. 5) According to modified TMN staging system, 3 cases were stage I, 2 cases stage II, 2 cases stage III and 2 cases unknown in our series. 6) Surgical resection was done on 7 patients, of whom 5 patients received chemotherapy and 2 patients both combined chemotherapy and radiotheyapy. The 2-years survival rate of our seriea was 55.6%.
