title: [Value of beta-HCG blood levels in patients with malignant tumors of the testis].
abstract: In 24 of 43 patients (56%) with malignant germ cell tumors of the testis, the serum was positive for HCG prior to ablation of the testis. We give a detailed account of the course of HCG levels in the serum of 7 patients with seminoma of the testis. Positive serum-HCG-findings 8 to 10 days after semi-castration and prior to retroperitoneal lymphadenectomy indicate tumor metastases. In two thirds of our patients, we observed a correlation between regression of metastases under chemotherapy and the pattern of serum-HCG-levels.
