Genomic and Transcriptomic Landscape of Triple-Negative Breast Cancers: Subtypes and Treatment Strategies

Abstract

Jiang et al. characterize primary Chinese triple-negative breast cancer (TNBC) and classify it into four subtypes. They find that these TNBCs have more frequent PIK3CA mutations and chromosome 22q11 copy-number gains than non-Asian TNBCs and that the LAR subtype has more ERBB2 somatic mutations and CDKN2A loss.
