Establishing and validating a nomogram to predict PFS for patients with ENKTL received nonanthracycline-based treatment. (A) A nomogram (nomogram A) comprising the 7-SNP–based classifier, age, Ann Arbor stage, lymph node involvement, LDH, and nonnasal type was constructed to predict 1-, 3-, and 5-year PFS. Time-dependent ROC curves and AUCs for evaluating the 5-year PFS (B) and OS (C) predictive accuracy of nomogram A, IPI, KPI, and PINK in 4 cohorts.
