The purpose of this study is to evaluate the health related quality of life (QoL) of head and neck cancer (HNC) patients with cancer-free survival after treatment and to investigate the factors correlated with their health-related QoL. The European Organization for Research and Treatment of Cancer (EORTC) Core Quality of Life Questionnaire (QLQ-C30) questionnaire and the EORTC head and neck cancer-specific questionnaire (QLQ H&N-35) were self-administered by all participating patients. Sociodemographic data were collected using a questionnaire specifically designed for the study and through the medical chart reviewed. The patients who have been treated radiotherapy in our department of radiation oncology were invited to participate Health-related quality of life was assessed 3 months or later after completion of radiotherapy. Data relating to sociodemographic factors, disease characteristics and treatment factors of HNC survivors were analyzed. A total of 141 head and neck cancer patients completed the questionnaires. After data analysis, the results are described as follows: In the results of EORTC QLQ-C30 questionnaire, the score of ¡§global health status¡¨ is 69.34. Most of the patient could maintain good functional quality of life. ¡§Fatigue¡¨ is the most impaired symptom score in the patient. In the results of EORTC QLQ-H&N35, the three head and neck specific symptom scores indicating the most impaired in QOL were ¡§Weight loss¡¨, ¡§Nutrition supplements¡¨ and ¡§dry mouth¡¨. After analysis through the multiple regression model, we found sex, age, tumor subsite, radiotherapy technique and surgery were the independent factors significantly correlated with the QoL scales This study is helpful for us to understand the QoL status and the factors affecting the QoL for patients with head and neck cancer after radiotherapy.
