PATIENTS AND METHODS: From 4,754 patients registered in the database of the German Hodgkin Study Group from 1988 to 1999, 624 patients were identified with progressive disease (n = 202), or with early (n = 170) or late (n = 252) relapsed HD. At first treatment failure, SRT alone was given to 100 patients. Patient characteristics were: median age, 36 years; progressive disease, 47%; early relapse, 23%; late relapse, 30%; and "B" symptoms, 14%. Eighty-five percent of the patients relapsed after cyclophosphamide, vincristine, procarbazine, and prednisone/doxorubicin, bleomycin, vinblastine, and dacarbazine (COPP/ABVD) like regimens; 8% after bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP) regimens, 7% after first-line radiotherapy alone. RESULTS: The volume irradiated was mantle field in 43% of patients, inverted-Y in 8%, total nodal irradiation in 12%, and involved-field in 37%. The median SRT dose was 40 Gy (range, 15 to 50 Gy). Seventy-seven patients achieved a complete remission and four patients achieved a partial remission. The 5-year freedom from treatment failure and overall survival (OS) rates were 28% and 51%, respectively. In multivariate analysis, significant prognostic factors for OS were B symptoms (P = .018) and stage at relapse (P = .014). For freedom from second failure (FF2F) Karnofsky performance status (P = .0001) was significant. In patients with limited stage at progression/relapse, duration of first remission was significant (P = .04) for FF2F. CONCLUSION: SRT offers an effective treatment for selected subsets of patients with relapsed or refractory HD.
