ABSTRACT
Objective:
To evaluate the role of Tg in diagnosis of lateral cervical lymph node recurrence in papillary thyoid cancer(PTC)after radioactive iodine(RAI) therapy.Methods:
From Jan 2012 to Aug 2018, 22 PTC patients who received RAI therapy after operation were reoperated for lateral cervical lymph node recurrence. The clinical data was retrospectively analyzed.Results:
The median recurrence time was 30.5 (5-86) months. All 22 patients received RAI therapy after the first operation, and the median dose of RAI was 250mCi(100-700 mCi) and the episode of RAI therapy ranged from 1 to 4. All 22 PTC patients underwent neck reoperation, among which 20 cases were identified to have lymph node metastasis. The median number of lymph nodes dissected was 31 (8-83) and median number of metastatic lymph nodes was 4 (1-19) . The diagnostic accuracy of ultrasonography in detecting lymph node metastasis was 90.9%. Before reoperation, the median Tg was 1.305 (0.10-99.51) μg/L, with the cutoff value of Tg being 0.2 μg/L, and its sensitivity and specificity were 80.0% and 100%, respectively. The median stimulated Tg was 5.89 (0.14-255.80) μg/L in the 10 patients, with the cutoff value of stimulated Tg of 2 μg/L, and its sensitivity and specificity were 88.9% and 100%, respectively.Conclusions:
The serum Tg level is helpful for monitoring the recurence of PTC, but recurrence cannot be completely ruled out for those with low Tg.
