RESUMEN
INTRODUCTION: Thyroid cancer diagnosis often evokes strong negative emotions in patients, yet little is understood about such responses in those with benign thyroid nodules. This study explored the impact of a hypothetical cancer diagnosis, the provision of treatment information, and emotional support from surgeons on patients with benign nodules. METHODS: Patients within 30 d of a thyroid nodule biopsy were asked to imagine their nodule was cancerous and write down their feelings about this diagnosis. They then viewed a video depicting a patient-surgeon discussion of thyroid cancer treatment options, with or without added emotional support (1:1 randomized allocation). Validated measures assessed anxiety and thyroid cancer-related fear before and after video-viewing. Thematic analysis evaluated participants' feelings about the hypothetical diagnosis. RESULTS: Of 221 eligible patients, 118 participated (53.4%). While participants state anxiety increased after performing the thought exercise and watching the video (9 [6, 11]-12 [8, 14]; P < 0.001), thyroid cancer-related fear decreased over the same period (27 [22, 30]-25 [20, 29]; P < 0.001). Emotional support by the surgeon in the video did not affect anxiety or fear. Themes that emerged from participants imagining they have thyroid cancer included information seeking, trust in medicine, cancer experience, thyroid cancer knowledge, apprehension about surgery, and impact on family. CONCLUSIONS: Patients with recently diagnosed benign thyroid nodules experience heightened anxiety when contemplating thyroid cancer. Provision of treatment and disease information mitigates cancer-related fear, while emotional support does not. Offering patients with thyroid nodules information about thyroid cancer before biopsy may offer emotional benefits.
