Abstract
Background: Patient preferences pertaining to surgical options for thyroid cancer management are not well studied. Our aim was to conduct a discrete choice experiment (DCE) to characterize participants' views on the relative importance of various risks and benefits associated with lobectomy versus total thyroidectomy for low-risk thyroid cancer. Methods: Adult participants with low-risk thyroid cancer or a thyroid nodule requiring surgery were asked to choose between experimentally designed surgical options with varying levels of risk of nerve damage (1%, 9%, 14%), hypocalcemia (0%, 3%, 8%), risk of needing a second surgery (0%, 40%), cancer recurrence (1%, 3%, 5%), and need for daily thyroid hormone supplementation (yes, no). Their choices were analyzed using random-parameters logit regression. Results: One hundred fifty participants completed an online DCE survey. Median age was 58 years; 82% were female. Twenty-four participants (16%) had a diagnosis of thyroid cancer at the time of completing the survey, and 126 (84%) had a thyroid nodule necessitating surgery. On average, 35% of participants' choices were explained by differences in the risk of cancer recurrence; 28% by the chance of needing a second surgery; 19% by the risk of nerve damage; and 9% by differences in risks of hypocalcemia and the need for thyroid hormone supplementation. When accounting for differences in postoperative risks, the average patient favored lobectomy over total thyroidectomy as long as the chance of needing a second (i.e., completion) surgery after initial lobectomy remained below 30%. Participants would accept a 4.1% risk of cancer recurrence if the risk of a second surgery could be reduced from 40% to 10%. Conclusions: While patients with thyroid cancer may have clear preferences for extent of surgery, common themes moderating preferences for surgical interventions were identified in the DCE. Adequate preoperative evaluation to decrease the chance of a second surgery and providing patients with a good understanding of risks and benefits associated with extent of surgery can lead to better treatment decision-making.
