Therefore, our study aims to investigate the prognostic impact of MCV and RDW on survival in skull base chordoma patients.Methods: Levels of preoperative MCV and RDW in 187 primary skull base chordoma patients were collected. X-tile software was used to find the cutoff values of MCV and RDW. Progression-free survival (PFS) and overall survival (OS) analyses were performed using the Kaplan–Meier methods, Cox analysis, and nomogram model.Results: Low MCV level (MCV < 84.2) was more commonly observed in classical chordoma patients (p=0.022). High RDW level (RDW≥ 12.7) was correlated with older patient age (p=0.022) and a tough tumor texture (p=0.035). Low MCV level and high RDW level were associated with poor PFS (p=0.045 and 0.007, respectively) and OS (p=0.023 and < 0.001, respectively). Multivariate Cox analysis demonstrated that RDW was an independent prognostic indicator for both PFS (p=0.001) and OS (p< 0.001). Importantly, a nomogram based on RDW and clinical predictors showed satisfactory performance for PFS and OS prediction (concordance index, C-index: 0.684 and 0.744, respectively).Conclusion: Our data was first to reveal the prognostic role of RDW in skull base chordoma, and identified the use of RDW may contribute to a more accurate prognosis judgment and personalized treatment decision.Keywords: skull base chordoma, mean corpuscular volume, red cell distribution width, survival analysis, biomarker
