Genomic testing in early stage invasive male breast cancer: An NCDB analysis from 2008 to 2014.

Rates of testing and distribution of RRS in men and women with early stage invasive breast cancer are similar. Treatment patterns in MBC varied significantly based on genomic testing results, even when adjusted for other clinicopathologic features. Further investigation is required to determine the prognostic and predictive nature of genomic testing in male breast cancer.
