The dynamic evaluation of 131I therapy response in papillary thyroid microcarcinoma patients
摘要
This retrospective study explored the use of different cut-off values for serum thyroglobulin antibody (TgAb) to judge the outcomes of 131I for papillary thyroid microcarcinoma (PTMC). After 131I therapy and TSH suppression, excellent response rates (ERRs) increased over time by both TgAb standards (TgAb < 10.0 KIU/L and TgAb < 115.0 KIU/L) but were significantly higher using the manufacturer cut-off (6.7 versus 22.2%, at 1 month; 8.9 versus 42.2%, at 4 months; 13.3 versus 48.9%, at 10 months; p < 0.01). Hence, the positive rate and ERR of TgAb in PTMC patients were significantly effectuated by the adopted cut-off value.
