Observation of changes in quality of life for 5 years after thyroid surgery: an observational cross-sectional study in Korean population

ABSTRACT

Purpose@#As thyroid cancer patients are experiencing longer disease-free survival periods, evaluating their quality of life after surgery has become crucial. However, studies on this topic have primarily focused on Western populations, leaving a gap in understanding the Korean patient population’s experiences and needs. This study aims to address this gap and provide insights into the quality of life of thyroid cancer patients in Korea. @*Methods@#This cross-sectional study evaluated the quality of life of Korean thyroid cancer patients who underwent thyroid lobectomy or total thyroidectomy. Patients were surveyed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ-C30, ver. 3.0) during outpatient clinic visits from January to September 2015. The results were analyzed by comparing them to scores of the general population and based on the time elapsed since surgery. This approach allowed for a comprehensive evaluation of the quality-of-life outcomes in this patient population. @*Results@#The study found that thyroidectomy had a notable impact on patients’ role and cognitive functions. Patients also experienced worsened symptoms such as fatigue, dyspnea, and constipation, which improved over time and returned to normal levels. However, there were no significant changes in other functions and symptoms after surgery. @*Conclusion@#The study’s findings showed that thyroidectomy had a relatively minor impact on the functional and symptomatic well-being of patients. Therefore, the results suggest that thyroid surgery may be a safe and effective treatment option for thyroid cancer patients seeking to maintain a good quality of life.
