| Abstract: | Risk factors for local-regional recurrence of breast cancer were analyzed in a retrospective review of 117 patients treated with adjuvant CMF (Cytoxan [Mead Johnson & Co, Evansville, Ind], methotrexate, 5-fluorouracil) after radical or modified radical mastectomy at the Vincent T. Lombardi Comprehensive Cancer Center (Washington, DC). The median follow-up time was 50 months after mastectomy. The median time to recurrence was 23 months. The actuarial local-regional failure rate was 19% at five years. Risk of local failure correlated with size of primary (27% for T3 v 15% for T1) and axillary node status (36% for four or more positive nodes v 9% for three or fewer positive nodes). These findings suggest a rationale for the addition of postoperative radiation therapy in high-risk patients treated with adjuvant chemotherapy. |
