Can magnetic resonance imaging be used to select patients for sentinel lymph node biopsy in prophylactic mastectomy?

Abstract

Occult cancer was identified in 5% of PMs. PM with or without SLNB spared only 4 of 393 patients (1%) from undergoing ALND, whereas PM alone identified unsuspected invasive disease in 3 of 136 patients (2%). When performed, MRI accurately ruled out the presence of an invasive cancer in the prophylactic breast, suggesting that MRI can be used to select patients for PM without SLNB.
