title: Adjuvant chemotherapy of axillary node-negative carcinoma of the breast using doxorubicin and cyclophosphamide.
abstract: One hundred fifty-six women with axillary node-negative breast cancer and primary tumors less than or equal to 5 cm in diameter (T1N0 or T2N0) were treated with a brief course of postoperative adjuvant chemotherapy consisting of doxorubicin and cyclophosphamide. Treatment was well tolerated and toxicity was minimal. With a median follow-up time of 58 months, there has been 1 relapse among 58 patients with T1 primary lesions and 15 relapses among 98 patients with T2 primary tumors. When compared with a matched historical control group receiving surgery alone, significant improvement was apparent in disease-free survival among the patients who received adjuvant chemotherapy. Prospective controlled trials are needed if we are to confirm this favorable experience with adjuvant chemotherapy in the treatment of women with node-negative breast cancer.
