    Excerpt:
    We sequenced tumor exomes from 135 lung cancer patients (79 with EGFR-wildtype (WT), 56 with EGFR-mutant tumors) enrolled in the ALCAPONE trial...Seven polymorphisms spread along three other genes: HLA-DRB5, KIR3DL1, and KIR3DL2, were associated with a worse PFS in patients receiving an EGFR TKI treatment. These included the following three variants in the HLA-DRB5 gene: rs1071748 (c.119A > G, p.(Asp40Gly)), rs184278615 (c.160C > T, p.(Arg54Trp)), and rs201469165 (c.163 T > A, p.(Phe55Ile)) (HR = 2.52 [1.24–5.09] p = 0.008, HR = 3.49 [1.58–7.68] p = 0.001, and HR = 2.78 [1.31–5.89] p = 0.005, respectively...
