The effect of early oral nutritional supplements on improving nutritional outcomes and radiation-induced oral mucositis for nasopharyngeal carcinoma patients undergoing concurrent chemoradiotherapy

Background: To explore the value of early oral nutritional supplements (ONS) in patients with nasopharyngeal carcinoma (NPC) treated with concurrent chemoradiotherapy (CCRT).Methods: Patients with newly diagnosed II-IVA stage NPC were analyzed and divided into Early and Routine ONS groups according to whether they received early ONS at the beginning of CCRT. Changes in nutritional indicators, incidence of treatment-related toxicity, radiation interruption, and completion of CCRT were compared.Results: In total, 161 patients with NPC were analyzed, including 72 in the Early ONS group and 89 in the Routine ONS group. Multivariate analysis showed that early ONS was an independent protective factor for concurrent chemotherapy =2 cycles, and a protective factor against =grade 3 radiation-induced oral mucositis (RIOM) and weight loss >5%. In stage III-IVA patients, early ONS was beneficial in decreasing the risk of severe malnutrition.Conclusions: Early ONS can improve nutritional outcomes, reduce RIOM, and enhance treatment adherence.
