This study evaluated the prognostic value of an unstimulated Tg (uTg) and Tg-DR papillary thyroid carcinoma (PTC). <b><i>Methods:</i></b> This retrospective study included 1818 Tg antibody (Tg-Ab)-negative patients who underwent curative intent total thyroidectomy for PTC without distant metastasis. The uTg was measured 1-3 months post-surgery under TSH suppression (<0.1 mIU/mL). We calculated the Tg-DR for patients, of whom postoperative Tg levels could be measured three or more times under TSH suppression. <b><i>Results:</i></b> Eighty-eight (4.8%) and 32 (1.8%) patients had respective local and distant recurrences (median follow-up period, 7.2 years; 25th percentile 4.7 years, 75th percentile 9.8 years). Of 1818 patients, 131 had a uTg ≥3 ng/mL and were more likely to display local and distant recurrences in univariate and multivariable analyses (<i>p</i> < 0.001). We divided 1212 patients with no adjuvant radioactive iodine treatment, of whom uTg and Tg-DR data were available, into four categories A, uTg ≥3 ng/mL and Tg-DR ≥0.33/year; B, uTg <3 ng/mL and Tg-DR ≥0.33/year; C, uTg ≥3 ng/mL and Tg-DR <0.33/year; and D, uTg <3 ng/mL and Tg-DR <0.33/year. The lymph node recurrence-free survival rate was significantly worse from category A to D (A vs. B, <i>p</i> < 0.001, hazard ratio or HR [CI]: 5.083 [1.994-12.955]; B vs. C, <i>p</i> = 0.001, HR [CI]: 2.654 [1.462-4.824]; C vs. D, <i>p</i> < 0.001, HR [CI]: 27.420 [15.100-4.980]). The distant recurrence-free survival rate (DR-FS) of category B did not differ from that of category C (<i>p</i> = 0.419), but DR-FS of category D was better (<i>p</i> < 0.001) than those of B and C, and that of category A tended to be worse (<i>p</i> = 0.087) compared with those of B and C. Patients in category A, categories B and C, and category D could thus be classified as high-risk, intermediate-risk, and low-risk for distant recurrence, respectively. <b><i>Conclusions:</i></b> This study demonstrates the prognostic value of postoperative uTg and Tg-DR in Tg-Ab-negative patients with PTC under TSH suppression after total thyroidectomy.

The practice guidelines of the American Thyroid Association (ATA) for DTC management in adult patients (previously combined with thyroid nodules) were published initially in 1996, with subsequent revisions based on advances in the field. The goal of this update is to provide clinicians, patients, researchers, and those involved in health policy with rigorous, comprehensive, and contemporary guidelines to assist in the management of adult patients with DTC, emphasizing the patient journey beginning with a thyroid cancer diagnosis. <b><i>Methods:</i></b> The questions addressed were based, in part, on prior versions of the guidelines, with input from a larger, more diverse complement of stakeholders. The panel included members from multiple specialties involved in thyroid cancer care, including a patient advocate and an expert in systematic reviews/meta-analyses/guidelines who educated and supported task force members. The panel conducted systematic literature reviews to inform the recommendations and commissioned two additional systematic reviews. Published English-language articles were eligible for inclusion, with a final search date of July 1, 2024. A modified Grading of Recommendations Assessment, Development and Evaluation system was used for critical appraisal of evidence and determining the quality of data. The guidelines panel had editorial independence from the ATA. Competing interests of task force members were pre-vetted, regularly updated, communicated with task force members, and assessed and managed by ATA leadership and the Clinical Practice Guidelines and Statements Committee. <b><i>Results:</i></b> These revised guidelines begin with the initial cancer diagnosis and continue with recommendations for staging and risk assessment, initial treatment decisions, assessment of treatment responses, monitoring approaches, diagnostic testing, and subsequent therapies based on the strength of evidence for response and consideration of side effects and outcomes. Patient-reported outcomes and identified areas of need for additional high-quality research are highlighted. <b><i>Conclusions:</i></b> These revised evidence-based recommendations inform clinical decision-making in the management of DTC that reflect the changing science and optimize the evidence-based clinical care of patients throughout their journey with DTC.

After excluding 28 patients with preexisting primary hypothyroidism, 811 patients were evaluated for the development of new-onset ICI-TD.
