Purpose: To investigate the prognostic value of nutritional markers for survival in nasopharyngeal carcinoma (NPC) patients receiving intensity-modulated radiotherapy (IMRT), with or without chemotherapy.
Patients and methods: This retrospective study included 412 NPC patients who received IMRT-based treatment. Weight loss (WL) during treatment, hemoglobin level (Hb) and serum albumin level (Alb) before treatment were measured. The prognostic values of these markers for overall survival (OS), locoregional recurrence-free survival (LRFS) and distant metastasis-free survival (DMFS) were analyzed using Kaplan–Meier method and Cox proportional hazards regression analysis. Propensity score matching was performed to reduce the effect of confounders.
Results: WL, Hb and Alb were significantly correlated with each other and inflammatory markers. Adjusted Cox regression analysis showed that critical weight loss (CWL) (WL≥5%) was an independent prognostic factor for OS (HR: 2.399, 95% CI: 1.267–4.540, =0.007) and LRFS (HR: 2.041, 95% CI: 1.052–3.960, =0.035), while low pretreatment Hb was independently associated with poor DMFS (HR: 2.031, 95% CI: 1.144–3.606, P= 0.016). However, no significant correlation was found between Alb and survival in our study cohort. The prognostic value of these markers was further confirmed in the propensity-matched analysis.
Conclusion: CWL, Hb and Alb have a significant impact on survival in NPC patients undergoing IMRT. They can be utilized in combination with conventional staging system to predict the prognosis of NPC patients treated with IMRT.
