Abstract

Background

Locoregional surgical pathology, with surgical margins at the primary site and lymph node (LN) metastasis, particularly extranodal extension (ENE), plays an important role in the prognosis of oral squamous cell carcinoma (OSCC). In addition, systemic inflammatory response and nutritional status are associated with poor prognosis.

Purpose

This study aimed to comprehensively assess the effect of inflammatory markers and locoregional factors on the prognosis of patients with OSCC who underwent neck dissection (ND).

Methods

This retrospective cohort study included patients who had undergone ND for OSCC between 2013 and 2021. The primary predictive variables were the weighted lymph node ratio (WLNR) and inflammatory markers. Primary outcome variables were overall survival (OS) and disease-free survival (DFS).

Results

Among 153 patients (99 males, 54 females), 55 (35.9 %) had LN metastasis and 11 (7.2 %) exhibited ENE. The inflammatory markers lymphocyte/monocyte ratio (LMR), monocyte/albumin ratio (MAR), C-reactive protein/albumin ratio (CAR), and WLNR demonstrated significant cut-off values for survival, with values of 4.805, 104.72, 0.041, and 0.0235, respectively. The Cox proportional hazards model revealed significant differences in age, WLNR, LMR, MAR, CAR, and vascular, lymphatic, and perineural invasion (Pn). Multivariate analysis indicated that the hazard ratios (95 % confidence intervals) for WLNR (3.416; 1.542–7.566), MAR (2.404; 1.254–4.607), and Pn (2.516; 1.291–4.905) were independent variables for OS.

Conclusions

In patients with OSCC who underwent ND, the inflammatory marker MAR and locoregional factors WLNR and Pn were simultaneously identified as prognostic factors.
