Testicular carcinoma in Denmark 1976-1980. Stage and selected clinical parameters at presentation.

Since Jan. 1, 1976 practically all new cases of germ cell tumours of the testis in Denmark have been included in the Danish Testicular Carcinoma Study (DATECA), permitting detailed registration of data concerning histology and stage at the time of diagnosis. The incidence of carcinoma of the testis in Denmark continues to be high with a crude rate of 8 to 9/100000 males per year. During the past 5 years the size of the primary tumours has decreased. Parallel to this, the rate of metastatic spread has decreased for seminoma, while no such change has been observed for non-seminomatous tumours. Data are presented on histology and stage for 1058 consecutive patients.
