Introdutcion: In recent years, thyroid microcarcinoma (TMC) predominates in the context of diagnosis and treatment of thyroid cancer. TMC has an excellent prognosis, its management is changed in the last few years, reducing surgical procedure and role of radioiodine ablation (RAI). Therefore, the question is what tests have a diagnostic value in patients with thyroid microcarcinoma after thyroidectomy

The aim of this study was to evaluate the role of 131 I whole body scan (WBS) in post operative assessment of patients with TMC.

Materials and methods: Retrospective analysis of the medical records of 446 consecutive patients with TMC. All patients were treated in one oncology centre between 2012 and 2021 with total thyroidectomy and were in low risk of recurrence group according to ATA stratification system (LR-ATA). During first assessment after the surgery ultrasound examination, stimulated thyroglobulin level, thyroglobulin antybody level and WBS were performed in all patients. Usefulness of WBS in planning further treatment was assessed.

Results: In all 446(100%) patients the radioiodine uptake in WBS was detected only in the thyroid bed. There was no pathological radioiodine uptake in any patients

Conclusion: Routine 131I WBS is not required for patients with LR-ATA TMC after total thyroidectomy. WBS does not affect further management.
