Abstract

While PI3K/AKT/mTOR pathway is altered in a variety of cancers including non small cell lung cancer, abnormalities in this pathway are more common in squamous cell lung carcinoma than in adenocarcinoma of the lung. Moreover, aberrant activation of PI3K/AKT/mTOR pathway is one of the mechanisms of acquired resistance to EGFR-TK inhibitors in patients with adenocarcinoma carrying EGFR activating mutations. Several inhibitors of the PI3K pathway are undergoing evaluation in preclinical and clinical studies. These include pan and selective inhibitors of PI3K, AKT inhibitors, rapamycin and rapalogs for mTOR inhibition, dual mTORC1-mTORC2 inhibitors and dual PI3K-mTOR inhibitors. This review focuses on recent preclinical and clinical data on the efficacy of PI3K pathway inhibitors in NSCLC either as monotherapy approach or in combination with chemotherapy or with drugs that target other signaling transduction pathways.
