Abstract
This study was performed to determine the risk of tumor recurrence after local excision alone in patients with small size (â¤1 cm) ductal carcinoma in situ (DCIS) of the breast. We have treated 107 patients who had DCIS measuring â¤1 cm with margin widths of â¥0.3 cm with excision alone per institutional protocol. With a median follow-up time of 58 months, 4 patients developed ipsilateral breast tumor recurrence (IBTR). Two of the 4 recurrences were invasive, whereas 2 were DCIS. The 5-year rate of IBTR was 6.1%. The patients with resection margin of <1.0 cm had significantly higher rate of IBTR than the patients with resection margin of â¥1.0 cm (23.1% vs. 1.5% at 5-year, p < 0.01). In conclusion, radiotherapy is necessary in the patients with resection margin of <1.0 cm after excision alone because of the substantial risk of IBTR.
