Locoregional treatment of breast cancer in women with and without preoperative magnetic resonance imaging.

ABSTRACT:

Background

Preoperative magnetic resonance imaging (MRI) use has increased among older women diagnosed with breast cancer. MRI detects additional malignancy, but its impact on locoregional surgery and radiation treatment remains unclear.

Methods

We examined the associations of preoperative MRI with initial locoregional treatment type (mastectomy, breast conserving surgery [BCS] with radiation therapy [RT], and BCS without RT) and BCS reoperation rates for Surveillance, Epidemiology, and End Results Medicare women diagnosed with stages 0 to III breast cancer from 2005 to 2009 (n = 55,997).

Results

We found no association of initial locoregional treatment of mastectomy (odds ratios [OR], 1.04; 95% confidence intervals, .98 to 1.11) or reoperation after initial BCS (OR,
