TREATMENT OF ADVANCED-STAGE MASSIVE MEDIASTINAL HODGKIN'S DISEASE : THE CASE FOR COMBINED MODALITY TREATMENT

In the initial series of 198 patients treated at the National Cancer Institute (NCI) with mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) chemotherapy for Hodgkin's disease, a review of presenting chest radiographs available on 192 of these patients showed 49 patients with mediastinal masses greater than one third the greatest posteroanterior chest diameter. Five patients had stage IIB disease, and 44 had stage III or IV disease. Thirty-five (71%) patients achieved a complete remission with MOPP chemotherapy. Fourteen (40%) of the complete responders relapsed, but four of these achieved durable remissions in response to subsequent therapy. Thirty (61%) patients have died (14 induction failures, nine relapsed patients, seven complete responders in remission). Thus, with a median follow-up of 20 years (range, 15 to 23), the overall survival for the group is 39%, and the disease-free survival for the complete responders is 60%. A subset of 10 patients received mantle radiation therapy after...
