Successful treatment of mediastinal seminoma with vinblastine, bleomycin, and cis-platinum.

We report on 2 patients with extensive primary mediastinal seminoma treated with vinblastine, bleomycin, and cis-dichlorodiammine platinum who achieved complete remission. These patients are alive forty-six months and sixty-six months without evidence of recurrence of disease. These long-term survivors extend the experience reported previously in the literature. Mediastinal seminoma with extent beyond a rational field of radiation therapy can be treated successfully with chemotherapy.
