Objective To analyse the clinical characteristics of extra-thyroid 99mTc-pertechnetate uptake in order to explore the effect of the phenomenon on radioactive iodine (RAI) therapy for differentiated thyroid carcinoma (DTC) and its clinical significance. Methods This study retrospectively selected patients with DTC and extra-thyroid 99mTc-pertechnetate uptake. The clinical features, location, location count and extra-thyroid 99mTc-pertechnetate uptake distribution were analysed, combined with the uptake rate, stimulated thyroglobulin (sTg) level, post-therapy whole-body scan and curative effect. Results A total of 38 patients were enrolled in the study and 65 extra-thyroid 99mTc-pertechnetate foci were detected. Thirty-four patients showed abnormal 99mTc-pertechnetate uptake in the lymph nodes (26 of 38; 68.4%), lungs (four of 38; 10.5%) and bones (four of 38; 10.5%). The corresponding uptake rates were 0.2%, 0.2% and 0.8%, respectively. The uptake rate and sTg were significantly positively correlated ( r = 0.36). 131I uptake was found in 36 patients at the 99mTc-pertechnetate uptake site. The number of iodine uptake foci was significantly higher than that of 99mTc-pertechnetate uptake foci. The sTg value and pathological staging significantly differed between the excellent and nonexcellent response groups (Z = –2.947 and Z = –2.348, respectively). Conclusion Extra-thyroid 99mTc-pertechnetate uptake mostly indicated metastases with specific clinical features, which may have prognostic value for the judgment of iodine uptake function and the RAI therapy plan.

Background: Over the last few decades, extra-thyroid 99mTc-pertechnetate uptake has rarely been reported. The clinical characteristics of extra-thyroid 99mTc-pertechnetate uptake were retrospectively analysed to explore the effect of the phenomenon on RAI therapy for DTC and its clinical significance. Methods: In this study, we retrospectively analysed 4930 RAI-treated DTC patients who had undergone 99mTc-pertechnetate scanning. Thirty-eight cases with extra-thyroid 99mTc-pertechnetate uptake were selected. The clinical features, location, location count and extra-thyroid 99mTc-pertechnetate uptake distribution were analysed, combined with the uptake rate, stimulated thyroglobulin (sTg) level, post-therapy whole-body scan and curative effect. Results: The results showed that sixty-five extra-thyroid 99mTc-pertechnetate foci were detected in 38 patients. The proportions of patients with abnormal uptake in the lymph nodes, lungs and bones were 68.4%, 10.5% and 10.5%, respectively. The corresponding uptake rates were 0.2%, 0.2% and 0.8%. The uptake rate was significantly lower in the lymph nodes than in the bones (Z = -2.722, p = 0.019). The uptake rate and sTg were positively correlated (r = 0.36, p = 0.027). 131I uptake was found in 36 cases at the technetium uptake site, and the number of iodine uptake foci was significantly higher than that of 99mTc-pertechnetate uptake foci. The sTg value and pathological staging significantly differed between the excellent and nonexcellent response groups (Z = 2.947, p = 0.003 and Z = 2.348, p = 0.019, respectively). Conclude: Extra-thyroid 99mTc-pertechnetate uptake mostly indicated metastases with specific clinical features, which may have prognostic value for the judgment of iodine uptake function and the RAI therapy plan.
