The median progression-free survival (PFS) in the PTEN and TP53 co-mutations group was the longest (7.5 months), while the median PFS in the PTEN mutations without TP53 mutations group was only 2.5 months....patients with NSCLC harboring PTEN and TP53 co-mutations might benefit more from immunotherapy compare to those harboring PTEN mutation without TP53 mutations and PTEN wild-type.
