520 Background: DCIS patients treated with lumpectomy have a very favorable outcome but are at risk for IBTR. Local control is improved by radiotherapy (RT) and adjuvant tamoxifen (TAM). Local failures, specifically invasive IBTRs (I-IBTR), may impact on long-term outcome. We present long-term outcome results from a cohort of DCIS patients from two NSABP randomized trials. Patients and Methods: A total of 2,615 women with primary DCIS from NSABP B-17 and B-24 (randomized from 1985 to 1994) were included. Median follow-up was > 12 yrs. In B-17 treatment was lumpectomy (LO, 403) or lumpectomy with whole breast irradiation (LRT, 410). In B-24 patients received LRT (901) or LRT plus TAM [901]. Hazard ratio and cumulative incidence of IBTR were examined by treatment. Mortality hazard was evaluated in relation to prior IBTR. Results: IBTR was a first failure in 465 patients (243 invasive, 222 noninvasive). The 12 year cumulative incidence of all IBTRs was 32.9% for LO, 15.8% LRT, and 12.5% LRT+TAM. RT significa...
