This study highlights the heterogeneity within TNBCs. Higher frequencies of PIK3CA mutations were noted in LAR subtypes and unclassified type, comparable to their incidence reported in literature in ER-positive tumors. The mutation status can be used as potential biomarker for PI3K inhibitors in TNBC subgroups.
