Abstract

BACKGROUND:

The purpose of the current study is to evaluate the outcome of salvage treatment for local recurrence after breast-conserving surgery and radiation as initial treatment for mammographically detected ductal carcinoma in situ (DCIS; intraductal carcinoma) of the breast.

METHODS:

An analysis was performed of 42 patients with local only first failure (n = 41) or local-regional only first failure (n = 1) after breast-conserving surgery and radiation treatment had been given for DCIS of the breast. Surgical treatment at the time of local recurrence included mastectomy (n = 37; 88%) or excision (n = 5; 12%). Adjuvant systemic therapy at the time of local recurrence was chemotherapy (n = 3; 7%), tamoxifen (n = 8; 19%), both (n = 1; 2%), none (n = 29; 69%), or unknown (n = 1; 2%). The median interval from the time of initial treatment to local recurrence was 4.8 years (range = 1.0-15.2 yrs). The median follow-up after salvage treatment was 4.5 years (range = 0.2-12.8 yrs).

RESULTS:

At the time of the local recurrence, 22 patients (52%) had invasive ductal carcinoma, 18 patients (43%) had DCIS, 1 patient (2%) had invasive lobular carcinoma, and 1 patient (2%) had angiosarcoma. After salvage treatment, the rate of overall survival and the rate of cause specific survival for all 42 patients were 92% at both 5- and 8-years after treatment. The rate of freedom from distant metastases was 89% at 5 and 8 years. Favorable prognostic factors after salvage treatment were DCIS as the histology of the local recurrence and mammography only as the method of detection of the local recurrence.

CONCLUSIONS:

The results of salvage treatment in the current study demonstrated that local recurrences were salvaged with high rates of survival and freedom from distant metastases. These results support the use of breast-conserving surgery and radiation for initial management of DCIS of the breast.
