Understanding the Factors That Influence Shared-Decision Making Around Surgical Resection of Low-Risk Thyroid Cancers: A Prospective Qualitative Study

<b><i>Background:</i></b> International guidelines now recommend adopting individualized approaches which consider patient preferences when deciding the extent of surgical resection for low-risk differentiated thyroid carcinoma (LRDTC). Information-sharing must be methodical to help patients make informed decisions without feeling overwhelmed by information. Understanding the factors influencing decision-making is therefore essential. <b><i>Methods:</i></b> Semi-structured interviews were conducted between May 2023 and June 2024 at two large tertiary referral centers in England, United Kingdom. Consecutive sampling via the multidisciplinary team meetings was used to identify patients newly diagnosed with LRDTC measuring 1-4 cm without adverse features, choosing between hemithyroidectomy and total thyroidectomy, or, if diagnosed following hemithyroidectomy, active surveillance and total thyroidectomy. Clinicians directly involved in their care were approached and recruited, with six consultant thyroid surgeons (five male, one female), and two thyroid cancer nurse specialists (both female), agreeing to participate. All had experience managing over 10 LRDTC patients annually. Transcripts were analyzed using the framework method of thematic analysis. <b><i>Results:</i></b> Twenty-four patients were identified, and 19 agreed to participate (13 female, 6 male). Information-sharing was often perceived as a didactic process, leaving patients overwhelmed with complex clinical details. Both groups emphasized tailoring information to meet patients' needs and delivering it in bite-sized portions to enhance comprehension. Key factors influencing individual decisions included a desire among most patients to minimize the number of, and extent of, surgical procedures, the need to preserve the thyroid gland and avoid hormone supplementation, and the patient's ability to accept the cancer recurrence risk. Although autonomy was paramount for patients, providers' recommendations still significantly impacted the final decision. Some clinicians expressed concern that multiple treatment options might confuse patients, instead entrusting decision-making to the multidisciplinary team meetings. <b><i>Conclusions:</i></b> This study identified essential information needs for LRDTC treatment decision-making, which can help inform the development of decision-support tools. Multidisciplinary team discussions may need to evolve to allow greater flexibility and support individualized decision-making.
