ABSTRACT
UNLABELLED: Between April 1994 and May 1997 103 breast cancer patients (pts), pT1c-3a, pN0-1, M0, were randomised after surgery to adjuvant tamoxifen (20 mg per day) or to tamoxifen plus CMF (C 500 mg/m2, M 40 mg/m2 and F 600 mg/m2 on days 1st and 8th q 28 day) in 6 cycles. The median age (49-72 years, median 58), tumour size, number of involved lymphnodes (0-3), estrogens receptor status, grade (I-III) and type of operation were well balanced among the 50 pts on tamoxifen and the 53 pts on tamoxifen plus CMF pts, preferably postmenopausal. RESULTS: Grade of toxicity according to WHO criteria was not higher then two in both arms. Toxicity both haematological and non-haematological was higher in the group treated with chemotherapy (0 vs 32 resp. 20%) except weight gain (52% in both group). After median follow-up of 42 mos five recurrences in tamoxifen and seven in tamoxifen plus CMF pts were observed (p = NS). The projected 3-y DFS is 92% for tamoxifen and 88% for tamoxifen plus CMF (p = NS). The 3-y OS is 88% for tamoxifen and 80% for tamoxifen plus CMF pts (p = NS). CONCLUSIONS: Both regimens are equally effective with higher toxicity in the group with combined chemo- and hormonal therapy.

The aim of this multicentric, prospective randomized trial is to evaluate and to compare, effects and toxicities of two chemotherapeutic combinations (AC and CMF) in adjuvant treatment of breast cancer. Both combinations were given in equitoxic doses and number of cycles was only four. There are 106 women treated for breast cancer T1c-3a, N0-1, M0 in the study. After surgery the patients were randomized, 54 for AC combination and 52 for CMF. We evaluate toxicity of this treatment in all patients in the study. Hematological and nonhematological side effects were comparable in both groups except alopecia (in the group AC was 100%). The study is not finished yet. Preliminary analysis does not show any difference between these two groups.
