Methodology Overview
This multicenter, retrospective study analyzed 132 intermediate-risk differentiated thyroid cancer (DTC) patients who underwent total thyroidectomy between 2018-2022. Patients were categorized into two groups based on the surgery-to-RAI interval: ≤6 months (Group 1, n=69) and >6 months (Group 2, n=63). Administered RAI activities were 3,700 MBq or 5,550 MBq. The primary outcome was excellent response (ER) at 6-month post-treatment, defined by ATA-2015 criteria. Multivariable logistic regression and 1:1 propensity score matching (considering age, sex, histology, multifocality, nodal status, and extrathyroidal extension) were employed to control for confounding factors. Sensitivity analyses included dose-stratified models. The median follow-up period was 18±6 months. The study aimed to determine if delaying RAI beyond 6 months negatively impacts early treatment responses in this patient population.
Summary of Key Results
The study found that excellent response (ER) at 6 months was significantly more frequent in Group 1 (35.6%) compared to Group 2 (21.2%, p=0.049). Conversely, incomplete biochemical responses were higher in Group 2 (15%) than in Group 1 (9.8%, p=0.033). After multivariable adjustment and in the propensity-matched cohort, an RAI delay of >6 months was independently associated with lower odds of ER (adjusted odds ratio 1.98; 95% confidence interval 1.05-3.74; p=0.035). Aggressive histology and nodal metastasis independently reduced the likelihood of ER. The adverse effect of the delay appeared stronger among patients receiving 3,700 MBq, though the dose-time interaction was not statistically significant. The number of doses required by patients in Group 2 was also higher (18% vs. 11%).
Strategic Implications
The findings suggest that timely administration of radioiodine therapy (RAI), specifically within 6 months post-thyroidectomy, significantly improves early excellent response rates in intermediate-risk differentiated thyroid cancer patients. This has crucial implications for healthcare providers: optimizing treatment pathways to minimize delays is paramount. For health systems, this translates to developing streamlined scheduling protocols, reducing logistical bottlenecks, and enhancing patient education on the importance of adherence to treatment timelines. Prioritizing earlier RAI for patients with aggressive histology or nodal metastases is especially important. Implementing AI-driven scheduling and patient management systems could facilitate these timely interventions, potentially improving patient outcomes and reducing the need for additional treatments, thereby enhancing operational efficiency and cost-effectiveness.
Study Limitations
This study has several limitations. Its retrospective design introduces potential selection bias and unmeasured confounding factors, despite attempts to mitigate this using propensity score matching and multivariable adjustment. Residual confounding cannot be entirely excluded. The relatively modest sample size (n=132) limited the precision of estimates in subgroup analyses, and the follow-up duration (median 18±6 months) may be insufficient to capture late recurrence events. The non-randomized allocation of 131-I activity and differences in TSH stimulation methods could also influence results. The exclusion of 27 intermediate-risk patients who did not receive RAI (due to patient choice, comorbidities, etc.) might have biased the analytic sample. Finally, the absence of systematic molecular data (e.g., BRAFV600E, TERT mutations) means that integration of molecular markers for refined risk stratification was not possible.

Case Study: Patient with Delayed RAI and Suboptimal Outcome
Patient number 11 received RAI >6 months post-thyroidectomy. Initial post-treatment scan showed continued uptake in the thyroid bed, indicating residual tumor activity. Tg levels were elevated, leading to an incomplete structural response. This patient eventually required additional imaging and follow-up due to persistent disease, highlighting the challenges associated with delayed intervention in some cases and the potential for increased resource utilization.
