[The diagnostic and prognostic value of tumor markers in nonseminomatous stage-III to -IV testicular tumors].

The effect of combined treatment was studied in 97 patients with nonseminomatous testicular tumors with regional and distant metastases with regard to the blood serum levels of alpha-fetoprotein and chorionic gonadotropin. The disease stage was found closely correlating with the efficacy of the treatment and the level of tumor markers. Complete remission was observed in 84.2 per cent (16 out of 19) patients with normal marker levels and in 26.8 per cent (11 out of 41) of those in whom both markers levels were raised (p less than 0.05). A continuous follow-up revealed that increased marker levels were the evidence of tumor relapse or metastases in clinically silent patients.
