Purpose: To evaluate the significance of elective splenectomy for Hodgkin's lymphoma. Materials and Methods: Elective splenectomy, total node irradiation (TNI) and chemotherapy (COPP) were performed in 36 patients with Hodgkin's lymphoma from May, 1979 to June, 1988. Result: Spleen invasion was proved in nine of eleven patients with Stage Ⅲ B MC who had been revealed as positive by or splenomegaly before. In stage Ⅲ B patients who were treated by total node irradiation (TNI), the leucopenia was lower in patients who received splenectomy (n=14) than those of without splenectomy (n=12)(P
