At present, abnormalities in PTEN have been confirmed to be closely related to the development, progression, and prognosis of glioma (Zhang et al., 2019), NSCLC (Shi et al., 2019), breast cancer (Xing et al., 2019), colon cancer (Liu et al., 2019), and other tumors. Here, PTEN is linked to non-small cell lung carcinoma.
