ATG9A and non-small cell lung carcinoma: Kaplan-Meier curve analysis showed that four protein levels were associated with PFS and/or OS: Low levels of ATG9A and high levels of SPTN2 were significantly associated with longer PFS (log-rank p < 0.001 and log rank p = 0.017 for ATG9A and SPTN2, respectively) in NSCLC patients.
