Abstract
One hundred consecutive Stage IIIA and IIIB Hodgkin's disease patients were treated between July 1969 and September 1976, on a combined chemotherapy‐radiotherapy program consisting of two courses of MOPP followed by radiotherapy to the mantle, abdomen, and pelvis. Eighty‐eight patients completed radiotherapy to all disease sites. At the time of this analysis, the mean follow‐up period for the 100 patients was 45 months; 70 patients had been followed three to seven years. Projected five‐year survival and disease‐free survival figures for the 100 patients were 80% and 68% respectively; corresponding results for the 88 patients were 90% and 78%. To determine whether any of the following prognostic factors influenced results for either the 100 or the 88 patients, survival curves were calculated for age, sex, constitutional symptoms, histopathology, method of staging, and status of the mediastinum. Other than age, none of these factors influenced survival significantly. However, disease‐free survival figures were influenced adversely by mediastinal disease as well as age.
