Two-year evolution of quality of life following radiotherapy and/or chemotherapy in patients with head and neck cancer

Abstract

ObjectiveThis study aims to elucidate the trajectory of quality of life (QoL) over a two-year period after radiotherapy and/or chemotherapy for head and neck cancer (HNC), addressing the gap in long-term QoL information. MethodsEmploying a prospective longitudinal observational design, we tracked 58 HNC patients who underwent radiotherapy and/or chemotherapy, analyzing their QoL using Short-Form 36-Item Health Survey version 2 (SF36v2), the European Organization for Research and Treatment of Cancer quality of life (EORTC-QLQ-C30), and the European Organization for Research and Treatment of Cancer quality of life head and neck-35 (EORTC-QLQ-H&N35) questionnaires for two years post-discharge. The data underwent repeated measures analysis of variance. ResultsOver the two-year follow-up, 10 patients (17.2%) succumbed, and 8 (13.8%) dropped out. SF36v2 physical and role-social component summary scores declined during treatment, requiring 1–2 years for recovery. The mental component summary score remained stable. EORTC-QLQ-30 revealed global health status recovery within one year post-discharge. EORTC-QLQ-H&N35 items like “swallowing,” “senses problems,” “trouble with social eating,” “dry mouth,” “sticky saliva,” “coughing,” and “felt ill” worsened pre-discharge. “Trouble with social contact” improved within a year, while “pain,” “swallowing,” “senses problems,” “trouble with social eating,” and “coughing” improved within two years. “Dry mouth” and “sticky saliva” persisted throughout the two-year follow-up, common symptoms of HNC and treatment side effects. ConclusionsRecovery of specific QoL aspects in HNC patients treated with radiotherapy and/or chemotherapy may require up to two years. Prolonged monitoring and management of oral symptoms could enhance QoL. Future research should extend follow-up beyond two years for comprehensive interventions enhancing patient QoL.
