Abstract

Background: The C-reactive protein/albumin (CRP/ALB) ratio has recently been associated with clinical outcomes in patients suffering various types of cancer. In this retrospective study, we investigated the prognostic value of the pre-treatment CRP/ALB ratio (CAR) in non-metastatic nasopharyngeal carcinoma (NPC) patients.

Methods: The cohort included 2685 patients with non-metastatic NPC. Univariate and multivariate COX proportional hazards analyses were applied to evaluate the associations of CAR with overall survival (OS), distant metastasis-free survival (DMFS), disease-free survival (DFS), and locoregional recurrence-free survival (LRRFS) in patients with NPC. Kaplan-Meier survival analyses was used to compare groups classified by CAR.

Results: Patients were categorised by the CAR using a cut-off value of 0.064. Multivariate Cox proportional hazard analysis verified that high CAR level was a significant predictor for inferior OS (P = 0.003), DMFS (P = 0.035), and LRRFS (P = 0.024), but not for DFS (P = 0.093). CAR was also an independent prognostic factor for OS when stratified by Epstein-Barr virus DNA level ( ≥ 2560 or < 2560 copies ml^-1).

Conclusions: High CAR provides prognostication regarding OS, DMFS, DFS, and LRRFS in patients with NPC. CAR is a valuable coadjutant for Epstein-Barr virus DNA levels for identifying survival differences.

Keywords: Nasopharyngeal carcinoma, C-reactive protein, albumin, Epstein-Barr virus DNA, prognosis.
