睾丸腫瘍の治療成績

Abstract

Fifty seven cases of testicular tumors were experienced for the last 16 years (from 1962 to 1978). These cases were reviewed with regard to their chemotherapeutic and prognostic features. 1. In the pathological classification, the testicular tumors in our series consisted of 32 seminomas, 9 embryonal carcinomas, 10 teratomas, and 3 teratocarcinomas. 2. In the distribution by age and pathological type, seminoma had a peak at the age of 20 to 40 and embryonal carcinoma had two peaks at the age of 0 to 9 and 20 to 30. 3. In the chemotherapy, the patients with seminoma (stage III) were administered cyclophosphamide and futraful and the patients with embryonal carcinoma and teratocarcinoma were almost administered actinomycin D. 4. The 5-year observed survival rate of seminoma was 83% and 5-year relative survival rate was 85%. 5. The 5-year observed survival rate of embryonal carcinoma was 100% and the 5-year relative survival rate was 100%. 6. The 5-year observed survival rate of all testicular tumors was 79% and the 5-year relative survival rate was 80%.
