[4-component chemotherapy and radiation therapy of breast cancer].

The treatment schedule for disseminated breast carcinoma has been developed. It includes the use of adriamycin (30 mg/m2, days 1, 8, 15), methotrexate (30 mg/m2, day 1), 5-FU (600 mg/m2, day 8), and cyclophosphamide (400 mg/m2, day 15 i. v. by jet injection). A complete response was obtained in 50 to 56% of the patients, with remissions lasting for an appreciable period of time. The use of chemotherapy according to the described schedule combined with radiation of the bones of the pelvis and lumbar part of the spine brought about complete or partial reparation of the osteolytic, osteoblastic and mixed metastatic foci in 76.2% of the patients.
