Abstract
Purpose: Although breast-conserving surgery followed by radiotherapy (RT) has become a standard treatment option for patients with ductal carcinoma in situ of the breast, risk factors for ipsilateral breast tumor recurrence (IBTR) in these patients remain an active area of investigation. The purpose of this study was to evaluate the impact of clinical and pathologic features on long-term outcome in a cohort of DCIS patients treated with breast-conserving surgery plus RT. Methods and Materials: Between 1973 and 1998, 230 patients with DCIS were treated with breast-conserving surgery plus RT at our institution. All patients were treated by local excision followed by RT to the breast to a total median tumor bed dose of 64 Gy. Adjuvant hormonal therapy was used in only 20 patients (9%). All available clinical, pathologic, and outcome data, including ipsilateral and contralateral events, were entered into a computerized database. The clinical and pathologic variables evaluated included detection method, mammographic appearance, age, family history, histologic subtype, presence of necrosis, nuclear grade, final margin status, and use of adjuvant hormonal therapy. Results: As of December 15, 2000, with a median follow-up of 8.2 years, 17 patients had developed a recurrence in the ipsilateral breast, resulting in a 5- and 10-year IBTR rate of 5% and 13%, respectively. Contralateral breast cancer developed in 8 patients, resulting in a 10-year contralateral recurrence rate of 5%. Patient age, family history, histologic subtype, margin status, and tumor grade were not significantly associated with recurrence on univariate analysis. A significantly higher rate of local relapse was observed in patients with the presence of necrosis. The 10-year relapse rate was 22% in 88 patients with necrosis compared with 7% in 142 patients without necrosis (p
