Background:The aims of this study were to evaluate the prognostic ability of the neoadjuvant rectal(NAR)score and to develop and validate a nomogram based on the NAR for patients with locally advanced rectal cancer(LARC)treated with neoadjuvant chemoradiotherapy(nCRT).Methods:In total,307 patients,including 230 patients from the primary cohort and 77 from the external cohort,were enrolled across the two *** associations of the NAR score with the tumor response,tumor control,and clinicopathological parameters were *** analysis was performed in the primary and external cohorts using Kaplan‒Meier *** and multivariate analyses were performed to evaluate the prognostic *** NAR-based nomogram was developed in the primary cohort and validated in the external cohort using the concordance index(C-index),calibration plots,and decision curve analyses(DCAs).Results:Kaplan‒Meier survival analysis revealed that the disease-free survival(DFS)and overall survival(OS)of the NAR>16 group were significantly lower than those of the NAR≤16 group(pclinical ***,the C-indexes of the NAR-based nomograms were better than those of the other variables in both the primary and external ***:Our study validates the prognostic role of the NAR score for DFS and *** NAR-based nomogram for OS could accurately predict the outcome of LARC patients by stratifying the risk score accordingly.
