Germ cell tumours of testis: prognostic factors and results.

Prognostic features regarding the outcome of 232 patients with testicular germ cell tumours treated from 1980 to 1987 in Sheffield are reviewed. Delay in diagnosis was a constant feature. The majority had a swelling for over 3 months. After 6 months mortality doubled, compared with patients with a shorter history. Initial serum levels of alpha-fetoprotein and beta-human chorionic gondadotropin, particularly if both were elevated over 100, and more so 500 IU/l, indicated a subsequent mortality in non-seminomatous tumours of 24 and 37%, respectively, while only 1.5% died if both values were below 100. The overall survival rate was 97% in seminomas and 78% in non-seminomas; no patients with well or moderately differentiated tumours died. There were no deaths after the 3rd year. Surveillance treatment in stage-I tumours was safe and mortality-free.
