Molecular Profiling Using Breast Cancer Subtype to Plan for Breast Reconstruction

imageBackground: Molecular profiling using breast cancer subtype has an increasing role in the multidisciplinary care of the breast cancer patient. The authors sought to determine the role of breast cancer subtyping in breast reconstruction and specifically whether breast cancer subtyping can determine the need for postmastectomy radiation therapy and predict recurrence-free survival to plan for the timing and technique of breast reconstruction. Methods: The authors reviewed prospectively collected data from 1931 reconstructed breasts in breast cancer patients who underwent mastectomy between November of 1999 and December of 2012. Reconstructed breasts were grouped by breast cancer subtype and examined for covariates predictive of recurrence-free survival and need for postmastectomy radiation therapy. Results: Of the reconstructed breasts, 753 (39 percent) were luminal A, 538 (27.9 percent) were luminal B, 224 (11.6 percent) were luminal HER2, 143 (7.4 percent) were HER2-enriched, and 267 (13.8 percent) were triple-negative breast cancer. Postmastectomy radiation therapy was delivered in 69 HER2-enriched patients (48.3 percent), 94 luminal HER2 patients (42 percent), 200 luminal B patients (37.2 percent), 99 triple-negative breast cancer patients (37.1 percent), and 222 luminal A patients (29.5 percent) (p
