对于患不同类型的甲状腺癌的病人行甲状腺全切除术常常是不完全的。术后I~(131)扫描可查出残余的甲状腺组织,但并不能确定残余组织是否被癌所累及。另一方面,行外科手术治疗的甲状腺癌病人,对其进行扫描检查,测定血清Tg(甲状腺球蛋白)能协助判断情况。怍者对已手术的早期分化较好的甲状腺乳头状癌(T_2,N_(?),M_9)25例病人进行了研究。所有病人术后用三碘甲状腺素治疗(1 ug/kg/日),以抑制残余甲状腺功能。40天后,停止这种抑制性治疗。以后每隔三天测定一次TSH(甲状腺刺激素)和Tg 浓度。当TSH 浓度超过50uU/ml 时,20天内每一病例需作一次扫描检查,停药20天后,每隔6
For patients with different types of thyroid cancer, total thyroidectomy is often incomplete. Postoperative I-131 scans can detect residual thyroid tissue, but it cannot be determined whether the residual tissue is involved in cancer. On the other hand, surgically treated patients with thyroid cancer undergo scan tests and determine serum Tg (thyroglobulin) to help judge the situation. The deaf man studied 25 patients who had undergone surgery for early differentiation of thyroid papillary carcinoma (T_2, N_(?), M_9). All patients were treated with triiodothyronine (1 ug/kg/day) after surgery to suppress residual thyroid function. After 40 days, this inhibitory treatment was stopped. TSH (thyroid stimulating hormone) and Tg concentrations were measured every three days thereafter. When the concentration of TSH exceeds 50uU/ml, one scan should be performed in each case within 20 days, and after 20 days of discontinuation, every 6
