Publication type: Clinical Trial; Randomized Controlled Trial

The H5 study of supradiaphragmatic Hodgkin's disease in clinical stages I-II consisted of two controlled trials adapted to patients considered to have either favorable or unfavorable characteristics, based on prognostic factors identified in two former studies by the European Organization for Research and Treatment of Cancer. Of 494 patients, 257 who were classified as having unfavorable prognosis qualified for the more intensive treatment and consequently were spared a staging laparotomy. They were randomized either to total nodal irradiation (TNI) (132 patients) or to treatment with mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) alternated with mantle irradiation (MOPP X 3-mantle irradiation-MOPP X 3; 3M) (125 patients). In complete responders (96%), the 6-year relapse-free survival was 77% in the TNI arm and 91% in the 3M arm (P = .02). Relapses in the initially involved and irradiated mantle area were less frequent in patients started on MOPP. The 6-year actuarial total survival (TS) (TNI, 82%, and 3M, 89%; P = .05) appeared to favor the 3M arm, but this difference disappeared when patients dying from causes unrelated to cancer were excluded from analysis. In men less than or equal to 40 years old, there was no difference in relapse-free survival, freedom from disease progression, or TS between the groups receiving TNI and 3M. Thus, TNI is a short and appealing treatment, especially because it preserves fertility. The same observation was true in women less than or equal to 40 years old. In addition, even irradiation less than TNI, which is meant to spare the ovaries, provided a TS similar to that for 3M.
