Clinical significance of STAT3/FOXM1/ATG7 signalling in response of EGFR-mutated NSCLC patients to EGFR-TKIs. A The proportion of high and low p-STAT3 (Y705), FOXM1, and ATG7 expression in EGFR-TKIs-sensitive (n = 32) and EGFR-TKIs-resistant (n = 31) patients. B Representative images of immunohistochemical staining for phosphorylated STAT3(Y705), FOXM1 and ATG7 in the tumour tissues from EGFR-TKIs-sensitive and EGFR-TKIs-resistant patients. Statistical analysis of IRS of the indicated proteins in each group is depicted. Scale bars, 20 μm. C The correlation of active STAT3, FOXM1, and ATG7 in EGFR-TKIs-resistant patients harbouring EGFR mutation. D Kaplan–Meier analysis of PFS in resistant patients after EGFR-TKIs treatment (n = 31) further stratified with low and high expression of phosphorylated STAT3(Y705), FOXM1 and ATG7 levels. [*P < 0.01, **P < 0.01, ***P < 0.001 as compared with the pre-EGFR-TKIs group]
