[Results of a clinical study of carminomycin in primary disseminated forms, recurrences and metastases of breast cancer].

A more than 50% regression of tumor was observed in 19% of 64 patients treated with carminomycin for advanced primary breast cancer, its recurrences and metastases. A clinically-significant effect of treatment was recorded in 42%, while tumor process was arrested for at least 3-4 months in 37% of cases. The index of more than 50% regression of tumor rose to 28% in a group of 27 patients, following repeated courses of the drug. Only a slight toxic side--effect was observed, repeated courses included. Moderate leukopenia and a slight cardiotoxic effect were registered in 17%; phlebitis--in 12%. Carminomycin treatment should be recommended for advanced primary breast cancer, its recurrences an metastases, when other chemotherapeutic means fail to stop tumor process.
