In this exploratory analysis, we evaluated associations of tumor-infiltrating lymphocytes (TILs), T-cell‒inflamed gene expression profile (TcellinfGEP), BRCA1/BRCA2 mutation (BRCAm) status, homologous recombination deficiency (HRD) status, and tumor mutational burden (TMB) with clinical outcomes. Here, BRCA1 is linked to neoplasm.
