[Comparison of three pathologic classifications (Rappaport, LSG and Working Formulation) for the treatment of non-Hodgkin's lymphoma].

Comparison of three pathologic classifications (Rappaport, LSG and Working Formulation) was made for 292 cases of non-Hodgkin's lymphoma who were treated at the Department of Radiology, Tokyo Medical and Dental University, from 1952 to 1984. The Working Formulation was found to be the most convenient classification for the treatment of non-Hodgkin's lymphoma in Japan. There were two remarkable characteristics in the cases of non-Hodgkin's lymphoma classified by the Working Formulation. They were better case distribution having a strong relation to clinical prognosis and fewer high-grade cases in Waldeyer's ring lymphoma.
