The exact risk of developing a second primary cancer following radiotherapy for testicular seminoma is not known. At the Northern Israel Oncology Center, between the years 1968‐1988, 75 patients with early stage (I,IIA) testicular seminoma were treated by orchiectomy followed by radiation therapy. The overall 10‐ and 20‐year survival probability was 95% and 90%, respectively. Eight patients (11%) developed nine second cancers, with a cumulative rate of one case per 1,000 years of follow‐up. The second primary cancers were: two bronchogenic carcinomas, one contralateral seminoma, one thymoma, one papillary carcinoma of the thyroid, one carcinoma of the stomach, one transitional cell carcinoma of the urinary bladder, one carcinoma of the colon, and one malignant melanoma. Three of these tumors developed within the irradiated field. Five of these eight patients are alive with no evidence of recurrent cancer. We conclude that patients treated for seminoma have an increased risk of developing a second cancer. There is a need for greater awareness of this possibility. The overall prognosis remains favorable.
