A Scoping Review of Patient Health-Related Quality of Life Following Surgery or Molecular Testing for Individuals with Indeterminate Thyroid Nodules.

Abstract

Molecular testing can reduce the need for diagnostic thyroidectomy in cytologically indeterminate thyroid nodules. However, the health-related quality of life in patients managed with molecular testing is not well studied. The objective of this scoping review was to identify and analyze the health-related quality of life outcomes in patients with indeterminate thyroid nodules who are expected to undergo or have undergone surgery or molecular testing. A comprehensive search was conducted on PubMed, Scopus, PsychINFO, and Embase to identify relevant studies. The search terms included "thyroid neoplasms" or "thyroid nodule" and "molecular testing" or "surgery" and "quality of life". The included articles were analyzed for their main study objective, study design, participant characteristics, and main results. Eight studies were included in this scoping review. Four evaluated the quality-adjusted life years for patients with indeterminate thyroid nodules. Three of these studies found that molecular testing slightly improved quality-adjusted life years compared to surgery, while one study found no difference. Two studies assessed surgical health-related quality of life outcomes and reported that patients with indeterminate thyroid nodules who were expected to undergo surgery favored surgical procedures, while those who underwent surgery experienced impaired health-related quality of life. Two studies evaluated molecular testing in patients with indeterminate thyroid nodules and found that the final molecular test result significantly impacted health-related quality of life outcomes. Patients with suspicious/positive molecular test results had worse symptoms of goiter, anxiety, and depression, while those with benign results had preserved health-related quality of life scores. Patients with benign results from molecular testing experience better health-related quality of life within the first year compared to those with benign surgical outcomes. This scoping review highlights the importance of considering health-related quality of life outcomes in the management of patients with indeterminate thyroid nodules. Benign molecular testing results yield better quality of life than benign surgical outcomes within the first year, suggesting molecular testing as a preferable option. Further research comparing the impact of surgery and molecular testing on health-related quality of life is needed to improve shared decision-making and patient outcomes.
