MYC and meningioma: Moreover, survival analysis (Survival package with log-rank test; threshold value of P value < 0.05) of key genes related to resting mast cells showed that the risk model constructed based on 9 key genes (CXCL8, MYC, CXCL2, CXCL3, TNFAIP3, FOSL1, HIST1H2BN, BCL2A1 and SLC2A3) could predict the prognosis of patients with meningioma.
