尽管分化型甲状腺癌(differentiated thyroid carcinoma,DTC)大多具有良好的预后,但是较高的术后复发率是不容忽视的事实,其40年累积复发率高达35%,并且有约1/3的复发患者死于该病[1]。手术是治疗DTC最主要和最有效的方式。目前国内手术及促甲状腺激素(thyroid stimulating hormone,TSH)抑制治疗DTC的不规范现象较普遍,是术后复发的主要原因。DTC较晚的分期及其去分化特性是DTC术后复发的次要因素。DTC术后复发只 Although most differentiated thyroid carcinomas (DTCs) have a good prognosis, the high postoperative recurrence rate is a fact that can not be ignored, with a cumulative recurrence rate of 40% at 40 years and a recurrence of about 1/3 The patient died of the disease [1]. Surgery is the most important and effective way to treat DTC. At present, the nonstandard treatment of DTC by surgery and thyroid stimulating hormone (TSH) is a common cause of postoperative recurrence. The later stages of DTC and their dedifferentiation are secondary to recurrence of DTC. DTC recurrence only
