Synthetic lethal combinations have also been found that can alleviate the drug resistance of some tumors; for example, AKT inhibitors reverse the resistance to EGFR-TKIs in NSCLC with PBRM1 mutation, and EGFR-TKIs reverse the resistance to MET and ALK inhibitors in NSCLC with SMARCE1 deletion [65, 66]. The gene discussed is PBRM1; the disease is non-small cell lung carcinoma.
