Combined modality therapy for advanced Hodgkin's disease: 15-year follow-up data.

Abstract

From 1969 through 1982, 184 patients with advanced Hodgkin's disease (HD) were treated with combined modality therapy (CMT) at Yale University. The data were reanalyzed in November 1986, with a mean follow-up of 10 years. The patient population consisted of 102 newly diagnosed stages IIIB and IV patients, and 82 patients who had relapsed after initial radical radiotherapy. From 1969 through 1978, the treatment program was induction chemotherapy with nitrogen mustard, vincristine, vinblastine, procarbazine, and prednisone (MVVPP) for three cycles (6 months) followed by low-dose radiation (1,500 to 2,500 cGy) for patients who had achieved complete remission (CR), to all disease sites present before the onset of chemotherapy. From 1978 to 1982, selected "poor-risk" advanced-stage patients received nitrogen mustard, vincristine, procarbazine, prednisone plus Adriamycin (doxorubicin; Adria Laboratories, Columbus, OH), bleomycin, vinblastine, and dacarbazine (MOPP-ABVD) induction chemotherapy, while the remaining patients were randomized between MVVPP and MOPP. One hundred fifty-one patients have achieved CR (82%); 23 (15%) of these 151 have relapsed, with the remaining 128 patients in continuous CR. A total of 62 patients have died, 45 due to HD, and 17 due to other causes. Twelve of these 17 patients died of second malignancies. The 15-year actuarial survival of all patients is 54%. It is 71% if deaths due only to HD are considered. Within the overall group of advanced HD patients, age and multiple extranodal sites of involvement continue to constitute adverse risk factors. The three drug programs used were all equivalent. No improvement resulted from the use of MOPP-ABVD in the poor-risk patients. These results compare favorably with those recently published by the National Cancer Institute (NCI). CMT resulted in an approximate 20% improvement in survival with no increase in second malignancies when compared with chemotherapy alone.
