- W2034305763 abstract "This study analyses and compares the results of local regional control, distant metastases and survival in two series of patients irradiated from 1986 to 1992 in our radiation oncology centre following quadrantectomy or tumourectomy for early stage breast cancer.The quadrantectomy group consisted of 152 women, 109 (72%) with T1 and 43 (28%) with T2 tumours. Axillary nodes in this group were positive in 51 (33%) patients. The tumourectomy group included 123 women, 71 (58%) with T1 and 52 (42%) with T2 tumours. Positive axillary nodes were found in 56 (46%) of these patients. All quadrantectomy and tumourectomy patients received a dose of 50 Gy in 5 weeks to the whole breast, followed by a 10-16 Gy electron boost. Node positive patients in the tumourectomy group also received 50 Gy to the axillary apex and supraclavicular region. In both surgical groups, node positive premenopausal and postmenopausal patients received adjuvant CMF or tamoxifen therapy, respectively.After a median follow-up of 58 months, 89% of women in the tumourectomy group and 87% in the quadrantectomy group were alive and 80 and 73%, respectively, were free of disease. Breast and nodal failures were detected in 4.9 and 0.8% of cases, respectively, in the tumourectomy group, as compared to 5.9 and 3.3% of cases, respectively, in the quadrantectomy group. Distant relapses were observed in 16 and 18% of patients in the former and latter groups, respectively. Actuarial overall and disease-free survival was similar in the two series, with 5-year rates of 90 and 72%, respectively, in the tumourectomy group, and of 91 and 78%, respectively, in the quadrantectomy group. The differences in survival are not statistically different.Our findings show that tumourectomy and quadrantectomy, followed by adequate radiotherapy, provide comparable results in terms of local-regional control and survival." @default.
