PURPOSE: To determine the efficacy of mantle radiation therapy alone in selected patients with early-stage Hodgkin’s disease. PATIENTS AND METHODS: Between October 1988 and June 2000, 87 selected patients with pathologic stage (PS) IA to IIA or clinical stage (CS) IA Hodgkin’s disease were entered onto a single-arm prospective trial of treatment with mantle irradiation alone. Eighty-three of 87 patients had ≥ 1 year of follow-up after completion of mantle irradiation and were included for analysis in this study. Thirty-seven patients had PS IA, 40 had PS IIA, and six had CS IA disease. Histologic distribution was as follows: nodular sclerosis (n = 64), lymphocyte predominant (n = 15), mixed cellularity (n = 3), and unclassified (n = 1). Median follow-up time was 61 months. RESULTS: The 5-year actuarial rates of freedom from treatment failure (FFTF) and overall survival were 86% and 100%, respectively. Eleven of 83 patients relapsed at a median time of 27 months. Nine of the 11 relapses contained at least a component below the diaphragm. All 11 patients who developed recurrent disease were alive without evidence of Hodgkin’s disease at the time of last follow-up. The 5-year FFTF in the 43 stage I patients was 92% compared with 78% in the 40 stage II patients (P = .04). Significant differences in FFTF were not seen by histology (P = .26) or by European Organization for Research and Treatment of Cancer H-5F eligibility (P = .25). CONCLUSION: Mantle irradiation alone in selected patients with early-stage Hodgkin’s disease is associated with disease control rates comparable to those seen with extended field irradiation. The FFTF is especially favorable among stage I patients.
