睾丸腫瘍130例について --5年生存率を中心に--

Abstract

1) For the last 28 years, 130 cases of testicular tumors were experienced, excluding secondary or capsular tumors. These tumors were histologically classified into seminoma (38.46%), embryonal carcinoma (23.83%), adult teratoma (14.61%), choriocarcinoma (3.85%), teratocarcinoma (1.54%), reticulum cell sarcoma (3.85%), and the others were mixed type of these tumors. 2) The cases having the ingredient of seminoma amounted 45. 15% in total (S-total) and accounted for nearly half of all the testicular tumors. Similarly, E-total accoumted for 2l.54% and Ch-total for 6.15%. 3) Embryonal carcinoma showed two peaks in the age distribution, one peaking at the age of 0~4 and the other at 25~29. Seminoma showed one peak at the age of 30~34. No histological difference could be found between adults and children cases of embryonal carcinoma. 4) The incidence of adult teratomas were fairly frequent in the young age group, but decreased gradually with the age. Five cases of reticulum cell sarcoma were found only in the aged. 5) The absolute 5 year survival was 96.0% in seminoma (87.0% in S-total), 52.0% in embryonal carcinoma (50.0% in E-total), and 0% in choriocarcinoma (12.5% in Ch-total), respectively. Our results can be comparable to those of foreign countries. The absolute 5 year survival was compared according to the method of therapy. 6) Six cases of seminoma, corresponded to 9.83% of S-total, occurred in cryptorchism, and 3 cases were found in the hypospadiac patients. In 2 cases, seminoma occurred bilaterally. 7) The prognosis of reticulum cell sarcoma was very poor, and the patients died after rapid detelioration. Orchiectomy seemed to have accelerated the course of disease.
