Patients with low TMB BRCA2 altered tumors had comparable OS with patients with high TMB tumors (median [IQR] OS, 44.0 [10.0-67.0] months vs 41.0 [13.0-80.0] months), and both groups had better OS than patients with low TMB WT BRCA2 tumors (median [IQR] OS, 16.0 [6.0-57.0] months; Pā<ā.001) (Figure 2C).
