title: [Use of the study of DNA metabolism enzyme activities as a test system in the treatment of breast cancer].
abstract: Blood serum activities of thymidine kinase, thymidine phosphorylase, adenosine deaminase, and 5'-nucleotidase were measured in normal women, women suffering from mastopathies and mammary carcinomas, aged 36 to 70. Blood serum activities of the studied enzymes in mammary carcinoma patients differed from these values in healthy women and those suffering from mastopathies; these differences were age-associated. Measurements of the time course of enzymic activities before and in the course of chemotherapy may be employed as a biochemical test to monitor therapy efficacy.
