Evaluation of therapeutic modalities in the control of Hodgkin's disease

The results achieved in three different studies carried out on patients affected by Hodgkin's disease are discussed. In study No. 1, 58 patients with pathological Stage I-II were treated with only a "Mantle" field irradiation. The complete remission (CR) rate was 98% with an actuarial overall survival of 90%, and a median of follow-up of 80 months. Thirty-one percent of patients relapsed. In study No. 2, 42 patients were randomly allocated to receive only MOPP chemotherapy versus extended field irradiation; CR rate was 68 and 95%, respectively (p less than 0.05). The overall survival rate was 100% in the radiotherapy group and 82% in the MOPP group. No relapses have been observed in patients treated with MOPP. In study No. 3, 218 patients affected by advanced Stage HD were randomly treated with 6 cycles of MOPP chemotherapy versus 6 cycles of ABVD chemotherapy. In the MOPP group the CR rate, the relapse-free survival rate (RFS), and overall survival (OS) rates at 60 months were 77, 68, and 76% respectively, whereas, in the ABVD group the CR, the RFS, and OS rates at 60 months were 75, 77 and 80% respectively, (p less than 0.05). These data and statistical comparisons are analyzed.
