Cognition and QoL After Thyroid Surgery

Cognitive Decline, Survivorship, Symptoms, Cognitive, Thyroid Cancer, Thyroid Nodule

The development of cognitive dysfunction can profoundly affect HR-QoL as well as the possibility of societal participation and ability to work, and thereby relevantly impacts prospects for cancer survivorship. The aim of the study is to obtain improved understanding of the scope and magnitude of objective cognitive dysfunction in DTC survivors, and its relation to subjective cognitive dysfunction, thyroid hormone levels, physical activity and HRQoL. This is done in a prospective study where patients operated for a thyroid nodule (Bethesda IV-VI, i.e., benign \[goitre with nodule and fibroadenomas\], low-risk DTC and intermediate-high risk DTC) are included and asked to serially perform online neuropsychological testing as well as to complete questionnaires related to HR-QoL, physical activity and additional psychological and physical complaints. Blood is analysed for levels of thyroid hormones and systemic inflammation.

The primary aim of this study is to prospectively assess objective cognitive functioning in patients undergoing thyroid surgery for different indications by means of an online neuropsychological test, the Amsterdam Cognition Scale (ACS). Three patient groups are defined; 1) patients with follicular adenomas, 2) patients with extreme low-risk differentiated thyroid cancer (DTC; pT1a and pN0/x tumours), 3) patients in all other DTC risk groups (i.e., low, intermediate and high-risk). The primary comparison confers to groups 1 and 3.
