摘要: PURPOSE: We reviewed our institution’s experience treating patients with ductal carcinoma-in-situ (DCIS) breast-conserving therapy (BCT) to determine the impact of patient age on outcome. PATIENTS AND METHODS: From 1980 1993, 146 were treated BCT for DCIS. All underwent excisional biopsy, and 64% re-excision. received whole-breast irradiation a median dose 45 Gy. Ninety-four percent boost tumor bed, total 60.4 slides every by one pathologist. The follow-up period was 7.2 years. RESULTS: Seventeen developed an ipsilateral local recurrence, 5- 10-year actuarial rates 10.2% 12.4%, respectively. rate failure 26.1% in younger than years versus 8.6% older (P = .03). On multivariate analysis, young independently associated recurrence index lesion (true recurre...
