[A clinical study of testicular tumors].
Fifty-eight of the 44,698 patients seen at our Department, between 1972 and 1984 had a testicular tumor. The incidence rate was 0.13%. The mean age of these 58 cases was 28.6 years and two peak distributions, one in the 0 to 5 year and another in 26 to 30 year age group were observed. Among them, 54 patients (93.1%) had chief complaints of painless testicular swelling at initial examination. The vast majority of them had unilateral tumors; 28 in the right and 29 in the left. Only one patient had bilateral seminomas. Histologically, 30 of them (51.7%) were seminoma, 8 were embryonal carcinoma (13.8%), 2 were teratoma (3.5%) and the remaining 18 had tumors of double or multiple histological type. Most of the seminomas were treated by a combination of high orchiectomy and radiotherapy, and chemotherapy was done mainly for non-seminomatous cases. The 5-year survival rate calculated by the Kaplan-Meier method was 100% for patients with low stage (I, II) seminomas and 62% for those with non-seminomatous tumors.
