During the 13-year-period from 1959 to 1971, a total of 126 cases of malignant lymphoma have been treated at the Department of Radiology, Iwate Medical University. 98 of these cases were reticulum cell sarcoma and they corresponded to 78% of the total cases. Such a high incidence of reticulum cell sarcoma as observed in our series coincides with other reports that pointed out much higher incidence of this disease in Japan than in American and European countries. Staging of cases after Rye classification of Hodgkin's disease revealed that the majority of the reticulum cell sarcoma were in the advanced stage. Crude 5-year survival rates in Stages I, II, III and IV were 54%, 24%, 11% and 0%, respectively. The present results indicated that the combined measure with chemotherapy appears to be effective in Stage III.
