From: Epidemiological study of HER-2 mutations among EGFR wild-type lung adenocarcinoma patients in China
DFS and OS were analyzed according to HER-2 mutations status and protein expression level, respectively. a DFS of HER-2 WT (n = 114) and HER-2 MUT (n = 9) patients; b DFS of HER-2 IHC (-) (n = 79) and HER-2 IHC (+) (n = 17) patients; C. OS of HER-2 WT (n = 37) and HER-2 MUT (n = 2) patients; D. OS of HER-2 IHC (-) (n = 14) and HER-2 IHC (+) (n = 1) patients. WT: wild type group, MUT: mutation group; and HER-2 IHC (-): the score 0 or 1; IHC (+): The score 2 or 3
