Abstract:
OBJECTIVES:Peripheral whole blood cell counts have been used as prognostic indicators for various cancers, but their predictive value in nasopharyngeal carcinoma remain unclear. This study aims to evaluate the prognostic significance of the pretreatment hemoglobin×lymphocyte/monocyte ratio (HLMR) in non-recurrent, non-metastatic NPC patients undergoing definitive radiotherapy.
METHODS:Clinical and follow-up data from 805 NPC patients who completed definitive radiotherapy or chemoradiotherapy were retrospectively analyzed. Pretreatment hemoglobin, lymphocyte count, and monocyte count were collected to calculate HLMR. Receiver operating characteristic (ROC) curves were used to determine the optimal cut-off value of HLMR. Patients were then classified into high and low HLMR groups. The association between HLMR and clinicopathological characteristic was assessed using chi-square tests. Independent prognostic factors for overall survival (OS) and progression-free survival (PFS) were identified using Cox proportional hazards models. A nomogram was constructed based on the independent predictors to estimate patient survival rates, and internal validation was performed using a validation cohort.
RESULTS:The ROC curve identified 605.5 as the optimal HLMR cut-off value for predicting 5-year survival. Multivariate Cox regression analysis revealed that T stage (HR=1.886, 95% CI 1.331 to 2.673, P<0.001), N stage (HR=2.021, 95% CI 1.267 to 3.225, P=0.003), Eastern Cooperative Oncology Group (ECOG) score (HR=3.991, 95% CI 1.257 to 12.677, P=0.019), concurrent chemoradiotherapy regimen (HR=0.338, 95% CI 0.156 to 0.731, P=0.006), and HLMR (HR=0.648, 95% CI 0.460 to 0.912, P=0.013) were independent prognostic factors for OS. A nomogram including T stage, N stage, and HLMR in the training cohort was constructed to predict 3-, 5-, and 7-year OS, with a C-index of 0.713. The area under the curves for predicting 3-, 5-, and 7-year OS were 0.744, 0.665, and 0.682, respectively. Calibration curves showed good agreement between predicted and observed survival rates. The above results were further confirmed in the validation cohort.
CONCLUSIONS:Pretreatment HLMR may serve as a promising prognostic biomarker for patients with nasopharyngeal carcinoma.
