Longitudinal measurements of neutrophil-to-lymphocyte ratio in nasopharyngeal cancer treated with concurrent chemoradiotherapy.

ABSTRACT:

Objective

We study factors affecting neutrophil-to-lymphocyte ratio (NLR) and its changes throughout the treatment (ΔNLR) of nasopharyngeal carcinoma (NPC) underwent chemoradiotherapy (CCRT) followed by adjuvant chemotherapy (AC) and oncological outcomes including overall survival (OS) and disease-free survival (DFS).

Methods

Data from 81 NPC patients was retrospectively evaluated. NLRs were obtained from first week of CCRT (pre-CCRT), last week of CCRT (end-CCRT), and at last cycle of AC (end-AC). Pre-CCRT NLR was categorized into "low" and "high". End-CCRT and end-AC ΔNLRs were divided into "increased" and "decreased" based on NLR at these two timepoints relative to the value at pre-CCRT. Associations between sex, age, cancer stage and NLR, ΔNLRs were investigated. OS and
