用血清甲状腺球蛋白（Ｔｇ）浓度测定和￣（１３１）Ⅰ显像，评定检测了８３例分化型甲状腺癌（甲癌）术后患者。在２３例￣（１３１）Ⅰ显像有转移灶者中有２０例伴有Ｔｇ值增高；对甲状腺素替代治疗者停药前、停药２周后的Ｔｇ值进行了对比；另外对１０例患者进行了５年随访。结果表明，血清Ｔｇ测定对诊断分化型甲状腺癌术后有否复发或转移是一种有效而简便方法，结合￣（１３１）Ⅰ显像更能提高诊断准确率。 Serum thyroglobulin (Tg) and 131I imaging were used to assess the postoperative outcome of 83 patients with differentiated thyroid cancer. Twenty patients with metastases in 23 patients with 131I imaging showed an increase in Tg value; Tg values ​​of patients with thyroid hormone replacement therapy before treatment and 2 weeks after drug withdrawal were compared; in addition, 10 patients Patients were followed up for 5 years. The results show that the determination of serum Tg for the diagnosis of differentiated thyroid cancer recurrence or metastasis is an effective and simple method, combined with 131I Ⅰ imaging can improve the diagnostic accuracy.
