[Chemotherapy of metastasizing breast cancers. Indications and results]

Combined treatment with three or five chemotherapeutic drugs was given to 115 women with metastasizing breast cancer. These were unselected cases. Three drugs (cyclophosphamide, methotrexate and prednisone) were given to 49 patients, with remissions occurring in 28, arrest in a further five. Five drugs (additional to the three mentioned ones: vincristine and 5-fluorouracil) were given to 66, with remission in 45 and arrest of the disease in another eight. There was no certain difference between the response to the two forms of treatment. Mean survival time for both forms was 13 months in the remission group and six months in the failure group.
