    Abstract:
    PURPOSE: To assess the results of treatment, patterns of failure, and prognostic factors for relapse in a contemporary cohort of patients with stage II seminoma. MATERIALS AND METHODS: From January 1981 and December 1993, 99 patients (median age, 35 years) with stage II seminoma (IIA, 41; IIB, 28; IIC, 24; IID, six) were managed at our institution. Eighty were treated with radiation therapy (RT) and 19 with chemotherapy (ChT). RESULTS: With a median follow-up of 6.7 years, the five-year overall actuarial survival was 94%, the 5-year cause-specific survival was 94%, and the 5-year relapse-free rate was 83%. Sixteen (20%) of the 80 patients treated with RT relapsed (median time to relapse, 9 months). Relapse occurred outside the irradiated area in all but two patients. Distant relapse sites included the supraclavicular fossa, bone (four patients, three with spinal cord compression), and lung/mediastinum. All 19 patients treated primarily with ChT achieved disease control and none has relapsed. The relapse rate at 5 years for patients with stage IIA to IIB was 11% (seven of 64), and 56% (nine of 16) for those with stage IIC to IID disease (P < .0001). No patient with IIC or IID disease treated with ChT relapsed as compared with 56% of patients treated with RT (0 of 14 v nine of 16, P = .002). CONCLUSION: Radiation therapy is highly effective in patients with stage IIA or IIB seminoma (89% were relapse free). In stage IIC or IID disease, although local control with RT is excellent, a 50% risk of distant relapse is unacceptable, and not all patients who relapse can be salvaged. Chemotherapy should clearly be the primary treatment in patients with stage IIC or IID seminoma.
