CCNU, melphalan, methotrexate, and prednisone (CAMP) versus cyclophosphamide, methotrexate, and 5-fluorouracil (CMF) in the treatment of advanced breast cancer in postmenopausal women.

Sixty-nine postmenopausal patients with advanced breast cancer were randomized to receive treatment with cyclophosphamide, methotrexate, and 5-fluorouracil (CMF) or CCNU, melphalan, methotrexate, and prednisone (CAMP). Response rate (partial and complete remission) was significantly higher with CMF (50%) than with CAMP (20%). Hematologic toxic effects were equally pronounced with the two combinations as were the other side effects with the exception of alopecia, which occurred most frequently with CMF.
