Our results indicate that interruption of both STAT3-survivin and ERK–BIM pathways is required for induction of apoptosis in NSCLC harbouring EML4–ALK, providing a rationale for combination therapy with ALK and MEK inhibitors in EML4–ALK-positive NSCLC patients for whom ALK inhibitors alone are ineffective. Here, STAT3 is linked to non-small cell lung carcinoma.
