[Serum ribonuclease activity in gynecologic neoplasms. The behavior of serum ribonuclease in ovarian cancer under cytostatic therapy].

Ribonuclease activity in the serum of patients with histologically confirmed ovarian carcinoma is significantly higher than in serum of patients with benign tumors of the ovary and that of healthy controls. In 847 samples collected during a period of 20 months the course of the ribonuclease activity of 41 patients receiving cytostatic treatment was determined. The ovarian carcinoma of all 41 patients was histologically ascertained. Three typical examples are presented.
