Abstract
A combination of mustine, vincristine (Oncovin), procarbazine, and prednisione (MOPP) and the same combination without prednisone (MOP) were compared in the treatment of stage IV Hodgkin's disease in a prospective randomized trial. The complete remission rates were 80% with MOPP and 44% with MOP; the difference was highly significant. Prednisone seems to be an important component of the MOPP combination in the management of stage IV Hodgkin's disease.
