NRAS and TP53 mutation and NF2 deletion were significantly related to patients without the response to CPIs (p < 0.05). Meanwhile, MYC and RPS6KB1 amplification were found with those with the response (p < 0.05). The median progression free survival (PFS) to ICIS was 5.9 months (95% CI 3.8 - 8.05 months).
