Kaplan–Meier curve for OS according to the MSKCC scoring system (A) and PCNSL LLR scoring system (B) in the validation cohort. The OS rates of patients in the low-, intermediate-, and high-risk groups of the MSKCC scoring system were significantly different overall, with 5-year OS rates of 33.3% (n = 16) and 40.9% (n = 49), and 11.6% (n = 19), respectively (P = 0.008). MSKCC scoring system could not discriminate patients within low-, and intermediate- groups in the validation cohort (P = 0.243) (A). PCNSL LLR scoring system can clearly distinguish patients within the low-, intermediate-, and high-risk groups in the validation cohort (P = 0.005) (B).
