Methods A total of 498 patients with stage III-IVA NPC applying IC and concurrent chemotherapy were reviewed (training cohort, n = 376; validation cohort, n = 122). Results Tumor response was an independent predictor for clinical outcomes. The nomogram included age, N stage, pretreatment Epstein–Barr virus DNA, lymphocyte-to-monocyte ratio, and tumor response achieved an ideal C-index of 0.703 (95% CI 0.655–0.751) in the validation cohort for predicting overall survival (OS), which outperformed than that of the TNM system alone (C-index, 0.670, 95% CI: 0.622–0.718). In addition, the nomogram could successfully classified patients into different risk groups. Conclusions We established and validated a precise and convenient nomogram based on tumor response for predicting the OS of LANPC patients. View on the web Inoreader.
