Brief chemotherapy associated with extended field radiotherapy in Hodgkin's disease. Long-term results in a series of 102 patients with clinical stages I-IIIA.

From 1972 to 1976, 102 patients with stages I-IIIA Hodgkin's disease (HD) were treated by chemotherapy with cyclophosphamide, vinblastine, procarbazine and prednisone (CVPP: two courses) associated with extended field radiotherapy. Staging included neither laparotomy nor splenectomy (clinical staging). Treatment included neither splenic irradiation nor maintenance therapy. Complete remission was achieved for 98 patients and 11 of them recurred up to 94 months after treatment. Median follow-up of this controlled study is 13 years. Disease free survival (DFS) is 87% at 6 years and 84% at 10 and 15 years. Overall survival is 77% at 10 and 74% at 15 years. Disease specific survival is better (91% at 10 and 87% at 15 years) since only 38% (10/26) deaths were due to HD. The other deaths (16/26) with no evidence of HD were due to second cancer and intercurrent disease. Prognostic analysis of DFS by log-rank test gives significance to the following factors: contiguous extra-nodal involvement (P = 0.008), more than 3 involved sites (P = 0.01), signs of compression (P = 0.02), clinical stage IIIA (P = 0.03), infradiaphragmatic stages I-II (P = 0.04). The potential risk of secondary cancer is difficult to assess.
