Methods： In 29 thyroid cancer patients with low or no expression of soda ／ iodide symporter, the radio frequency combined 1311 therapy was used, the whole-body scintigraphy and serum Ig were detected before and after the radiofrequency treatment. Results： The whole-body scintigraphy showed that 4 cases （4/29） before radiofrequenc_y treatment had positive iodine uptake, 19 cases （19/29） two weeks after radiofrequency treatment had the positive iodine uptake, 12 cases （12/29） four weeks after radiofrequency treatment had the positive iodine uptake. Four weeks after radiofrequency treatment, 5 cases had increased serum Ig levels, 17 cases had decreased serum Ig levels, 7 cases showed no change. 25 cases （25/29） were effective, 15 cases （15/29） were cured. Conclusion： The radiofrequency induced the non-expressed the sodium/iodide symporter of thyroid cancer cells regain the iodine intake ability, it improved the clinical efficacy of 131I therapy in dedifferentiated thyroid cancer.展开更多
