Prognostic value of KRAS mutation in advanced non-small-cell lung cancer treated with immune checkpoint inhibitors: A meta-analysis and review.
Immune checkpoint inhibitors (ICIs) have emerged as a promising treatment option in the fight against advanced non-small-cell lung cancer (NSCLC). KRAS is the most frequently mutated oncogene in NSCLC. We performed this meta-analysis to investigate if KRAS mutation status affects survival benefits of ICIs in patients with advanced NSCLC. ⋯ For patients with KRAS wild-type NSCLC, however, ICIs did not prolong overall survival over that with chemotherapy (hazard ratio = 0.88 [95% confidence interval, 0.68-1.13], P = 0.30). In conclusion, ICIs as a salvage therapy improved overall survival over that with docetaxel in advanced NSCLC patients with KRAS mutation, but not in those with KRAS wild-type tumor. These results suggest that KRAS mutation status may be a potential biomarker for survival benefits to ICIs.
