Four cycles of chemotherapy and regional radiation therapy for clinical early‐stage and intermediate‐stage Hodgkin's disease
Antineoplastic Combined Chemotherapy Protocols
Organ Sparing Treatments
To achieve a high percentage of durable complete remissions (CR) and prolonged survivals and reduce toxicity in patients with early-stage and intermediate-stage Hodgkin's disease, a randomized trial of four cycles of mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) versus four cycles of thiotepa, bleomycin, and vinblastine (TBV) combined with regional radiation therapy (RT) was conducted. For MOPP and RT, the CR percentage was 98% (60 of 61), and at 5 years, the percentage of patients in CR was 90%, with freedom from progression of 89% and overall survival of 91%. For TBV and RT, the CR percentage was 93% (55 of 59), with a 5-year duration of CR of 83%, freedom from progression of 81%, and overall survival of 91% (P greater than 0.15). The median follow-up was 65 months (range, 7 to 96 months). For 27 patients with clinical Stage IIIA, the CR percentage for MOPP and RT was 75% (12 of 16), with 1 relapse and 4 deaths. For TBV and RT, the CR percentage for clinical Stage IIIA was 73% (8 of 11) with 2 relapses and 2 deaths. Short-term toxicity except for transient leukopenia was less for TBV and RT than for MOPP and RT. Good results are achievable with combined treatment without excessive toxicity.
