Now, the investigators carried out a prospective study enrolling patients with thyroid cancer, who had received ablative thyroidectomy and /or radioactive iodine therapy for two more years. The investigators' study already enrolled seventy-three patients with thyroid cancer, and the investigators plan to enroll 30 new patients in this consecutive research study. All patients received total thyroidectomy under clinically surgical judgement in initial therapeutic option. The investigators also further found some difference between papillary thyroid cancer and follicular thyroid cancer, and the investigators will continue annually to closely monitor the change of U-Ex Tg and urinary exosomal galectin-3 between differently cellular types of thyroid cancers.
