[Investigations about the incorporation of nucleotide precursors in single cell suspensions of ovarian- and cervix-carcinomas under the influence of cytostatic therapy (author's transl)].

The behaviour of 34 carcinomas of the cervix and 30 ovarian carcinomas under the influence of cytostatic agents was investigated in vitro by the method of Volm et al. The ovarian carcinomas showed a significantly higher incorporation rate of nucleotide precursors in the single cell suspensions. The incorporation rate in "chemosensitive" carcinomas was higher than in "chemoresistent" carcinomas independent of the type of the carcinomas. Carcinomas with a high decrease in incorporation rates of nucleotide precursors under the influence of cytostatic drugs were called chemosensitive. A cyclophosphamide-sensitivity in vitro was found in 9% of the carcinomas of the cervix and in 34% of the ovarian carcinomas. An adriamycin-sensitivity in vitro could be shown in 17% of the carcinomas of the cervix and in 46% of the ovarian carcinomas. These findings agree well with the experiences of cytostatic therapy of these carcinomas.
