The prognosis of stage III breast cancer treated with postoperative radiotherapy and adriamycin-based chemotherapy with and without tamoxifen. Eight year follow-up results of a randomized trial.
Sixty-one patients with primary node positive stage III breast cancers were randomized to receive postoperative radiotherapy and doxorubicin-based chemotherapy (eight cycles of CAFt: cyclophosphamide, adriamycin, oral ftorafur) with or without tamoxifen as adjuvant treatment. The five-year overall survival for all patients was 49% (with tamoxifen 48% and without tamoxifen 50%) and disease-free survival 33% (with tamoxifen 27% and without 39%). Local control for all patients was only 64% despite the postoperative radiotherapy. There was no significant difference between these two treatment groups in overall and disease-free survival or local control. The prognosis of stage III breast cancer remains grim despite modern adjuvant therapy. In addition to more effective systemic treatment more effective local therapy is also needed in order to obtain satisfactory local control. The most important studies in stage III breast cancer with 5-year survival results are reviewed here.
