Impact of thyroidectomy on quality of life in benign goitres: results from a prospective cohort study.

Abstract

Benign thyroid diseases encompass a large spectrum of conditions that are chronic and subtle in nature. A majority of patients choose non-surgical management and continue living their daily lives with subconscious impairment of optimal functioning. We studied the effect of thyroidectomy on the quality of life (QoL) in patients with benign goitres. A prospective study was conducted on 50 patients between January 2017 and August 2018 using the ThyPRO 39 questionnaire. This is a disease-specific health-related questionnaire administered the day before surgery and 6 months following surgery. Data analysis was performed using EpiData Manager and EpiData Entry Client (v 3.1). The mean age of the cohort was 43.30 years ± 11.61, with a female preponderance (34:16). The most common indications for surgery were suspicion of malignancy and compressive symptoms in 34% and 30%, respectively. The most common histopathology reported was nodular/adenomatous hyperplasia (56%). Prior to surgery, the most common domains affected were emotional susceptibility and tiredness. Following surgery, a significant improvement in all domains of the ThyPRO 39 questionnaire were seen except for psychological well-being (p=0.126). In addition, the composite scores significantly improved (p<0.001). Younger age, female gender, and longer duration of goitre were the factors that significantly affected the outcomes in various domains. Patients with benign goitres have subtle impairment of QoL which showed significant improvement following thyroidectomy.
