睾丸腫瘍41例の臨床的観察

Abstract

A clinical survey was performed on 41 cases of testicular tumor treated at Kyoto Prefectural University of Medicine and Kyoto Second Red Cross Hospital from Jan. 1964 to Dec. 1977. The results were as follows. 1) Histopathological diagnosis according to the classification by Dixon and Moore was type I in 23 cases, type II in 3 cases, type III in 5 cases, type IV in 7 cases, type V in one case and epidermal cyst in one case. Thus germinal tumors occupied 98% out of all cases. One case (2%) of reticulum cell sarcoma was detected which was non-germinal. 2) A peak of occurrence was observed between 30 and 40 years old. The distribution differed between histological patterns. 3) Six patients (15%) had a history of scrotal trauma with indefinite period from trauma to the occurrence between the each case. 4) Two cases (4.9%) of testicular tumor associated with cryptorchism were observed. 5) The overall 3 year and 5 year survival rates were 83.8% and 79.1%, respectively. 6) In non-seminomatous germinal tumors, the survival rate of the group treated with radiation after orchiectomy was remarkably poorer than the group without radiation. 7) Out of 8 dead cases, only one case died at more than 3 years after the surgery.
