Multimodal treatment for locally advanced breast cancer. Result of chemotherapy-radiotherapy versus chemotherapy-surgery.

In a prospective randomized study, the efficacy of two combined modality approaches (chemotherapy plus radiotherapy or chemotherapy plus mastectomy) was tested in a total of 132 women with locally advanced breast cancer. Chemotherapy consisted of Adriamycin plus vincristine (AV) administered for three cycles before either local-regional modality and subsequently for seven additional cycles. Although a higher proportion of women achieved complete remission after mastectomy (100%) compared to women given radiotherapy (60%), the total response rate at the end of combined modality was identical (75%). There was no significant difference between the two treatment groups in terms of patterns of treatment failure, median duration of response, and total survival. Treatment was not influenced by menopausal or estrogen receptor status. Two patients of the surgical group showed Adriamycin-induced cardiomyopathy after cumulative doses less than 500 mg/m2. The results of present study failed to indicate that surgery per se improved the overall results including local control, over radiotherapy in a combined modality setting.
