Abstrakt: Objective: To investigate whether prognostic nutritional index (PNI) predicts patient survival outcomes in oral cavity squamous cell carcinoma (OSCC). Materials and methods: The data of a total of 360 patients subjected to primary surgery for OSCC were retrospectively analysed. Patients were categorised into high‐PNI (≥51.75) and low‐PNI (<51.75) groups based on the PNI cut‐off value attained from receiver operating characteristic analyses (p <.001), and the intergroup differences in clinicopathological features were determined. The Kaplan–Meier method and Cox proportional hazard model were employed to determine the survival prediction ability of the PNI, and a nomogram based on the PNI was established for individualised survival prediction. Results: A low PNI was noted to exhibit a significant association with shorter overall survival (OS) and disease‐free survival (DFS) (both p <.001). Multivariate Cox analyses showed that a lower PNI independently indicated shorter OS and DFS (hazard ratio [HR] = 2.187; p =.001 and HR = 1.459; p =.023, respectively). The concordance index and calibration plots of the PNI‐based nomogram revealed the high discriminative ability for OS. Conclusions: Preoperative PNI is a valuable biomarker for predicting OSCC prognosis, and the proposed PNI‐based nomogram can provide individualised prognostic prediction. [ABSTRACT FROM AUTHOR]
