...we intended to develop and characterize an immune response prediction signature (IRPS) to forecast the efficacy of immunotherapy….A ccRCC cohort with anti-PD-1 therapy was obtained as an external validation data set to verify the predictive value of IRPS....Patients in the IRPS low risk group had better PFS (HR:0.73; 95% CI: 0.54-1.0; P = 0.047).
