Abstract
PURPOSE: To analyze the impact of quality of life (QoL), nutritional and clinical indicators on overall survival in patients with head and neck squamous cell cancer (HNSCC) undergoing (chemo)radiotherapy. MATERIALS AND METHODS: At the beginning, at the end of (chemo)radiotherapy and during follow-up, QoL was prospectively assessed using the EORTC-QLQ-C30 and -QLQ-H&N35 questionnaires. Data were analyzed in 58 out of 220 screened patients, who were randomized into a control and intervention group. All patients received a nutritional assessment including bioelectrical impedance analysis (BIA), laboratory testing, and a screening for malnutrition based on the questionnaires MUST, NRS-2002 and Nutriscore at baseline and at the end of therapy. The intervention consisted of an individualized nutritional counseling every 2 weeks. RESULTS: Except for emotional functioning, dyspnea, financial difficulties, dental problems and weight gain, all other scales from the EORTC-QLQ-C30 and -H&N35 deteriorated during (chemo)radiotherapy. At first follow-up, patients of the control group experienced more nausea and vomiting compared to those of the intervention group (p = 0.02). After performing a multivariable model, dental problems at the end of therapy (HR: 1.03; 95% CI: 1-1.06; p = 0.03), HPV negativity (HR: 18.19, 95% CI: 1.61-204.17; p = 0.02), and baseline phase angle (HR: 0.09; 95% CI: 0.01-0.82; p = 0.03) were identified as predictors for overall survival. CONCLUSIONS: Factors influencing overall survival in patients with HNSCC undergoing (chemo)radiotherapy are complex and multifactorial. We were able to identify QoL-related (dental problems), clinical (HPV status) and nutritional (phase angle) factors as negative predictors for survival. This study was registered within the German Clinical Trials Register (DRKS00016862).
