Abstract:
An analysis of 107 cases of cryptorchidism and non-seminomatous germ cell cancer treated between 1960 and 1976 is presented. The incidence of cryptorchidism in patients with testicular cancer is 9.8%. Eighty patients presented with ipsilateral inguinal tumours, 12 with contralateral intrascrotal tumours and 15 with abdominal tumours. There were 52 embryonal, 36 teratocarcinoma, 9 teratoma, and 10 choriocarcinoma tumours. The 5 year survival for all patients was 52.3%. The age distribution, pathology and stage of the patients was similar to non-seminomatous tumours not associated with cryptorchidism.
