EGFR and non-small cell lung carcinoma: In light of the anti-autophagic effects of SAHA in vitro, to further determine whether SAHA enhanced the antitumor effects of EGFR-TKI in drug-resistant cells of NSCLC, we investigated the effects of the combination of EGFR-TKIs and SAHA on the viability of PC-9/AB2 and H1975OR using the CCK-8 assay.
