β¦ Synopsis
The effect of known chemotherapeutic programs in patients with breast cancer who developed metastasis during or after adjuvant chemotherapy with L-PAM plus 5-FU (PF) were studied. Thirteen patients failed while receiving adjuvant therapy at 3-22 months from the time therapy started. Three patients failed 6-28 months after 2 years of therapy. Thirteen patients received PF followed by cyclophosphamide, methotrexate, and 5-fluorouracil (CMF) at the time of progression on PF. Of these, ten received Adriamycin and vincristine (AV) at the time of progression on CMF. The response to CMF was 7%. No patient responded to AV after progression on CMF. Two of three patients treated with AV after failure on PF did respond, but both for only 6 months. This suggests that adjuvant therapy may render the tumor less responsive to further chemotherapy. Since most patients failed while on adjuvant therapy, this may indicate a poor prognosis regardless of the agents used.
