摘　　要：目的评估血清中期因子(MK)水平对甲状腺乳头状癌(PTC)术后患者^(131)Ⅰ治疗过程中新发转移的预测价值。方法接受甲状腺全切/次全切术和(或)颈部淋巴结清扫术的PTC患者241例,术后实施个体化^(131)Ⅰ治疗。在首次^(131)Ⅰ治疗前(T1)、首次^(131)Ⅰ治疗后10～12个月时(T2),采用MK检测试剂盒检测所有患者的血清MK,分别记为MK1、MK2。根据血清MK2水平将患者分成A、B、C组,血清MK2水平≤正常值上限(508. 57 pg/m L)者为A组,血清MK2水平>正常值上限且≤MK1者为B组,血清MK2水平> MK1>正常值上限者为C组。根据分组结果,比较各组患者T2时新发转移情况。以A组为对照组,采用Cox回归分析法计算B、C组患者新发转移的风险比(HR)和95%置信区间(CI)。结果 241例PTC患者中,55例患者在T2时出现新发转移灶,其中A组11例、B组28例、C组16例,C组患者T2时出现新发转移灶者与A、B组相比,P均<0. 01。Cox回归分析显示,B组患者新发转移的HR为3. 374(P <0. 05,95%CI为1. 328～5. 047),C组患者新发转移的HR为6. 731(P <0. 05,95%CI为3. 121～14. 800)。结论血清MK水平对PTC术后患者^(131)Ⅰ治疗过程中新发转移有一定的预测价值。Objective To evaluate the predictive value of serum midkine( MK) levels for new metastases during 131Ⅰ ablation treatment in postoperative patients with thyroid papillary carcinoma( PTC). Methods Totally 241 patients with PTC undergoing total thyroidectomy/subtotal resection and/or cervical lymph node dissection were treated with individualized 131Ⅰ ablation. The serum MK concentrations were determined before the first 131Ⅰ ablation treatment( T1) and 10-12 months after the first 131Ⅰ ablation treatment( T2),which were recorded as MK1 and MK2,respectively. According to the serum MK2 level,the patients were divided into groups A [serum MK2 levels less than or equal to the upper limit of normal value( 508. 57 pg/m L)],B( MK2 levels above the upper limit of normal and less than or equal to MK1),and C( MK2 levels above MK1 and the upper limit of normal value). According to the grouping,the new metastases were compared between the three groups at T2. Cox regression analysis was used to calculate the risk ratio( HR) and 95% confidence interval( CI) for new metastases in patients of groups B and C by taking the group A as the control group. Results Among 241 patients with PTC,new metastases occurred in 55 patients at T2,including 11 patients in the group A,28 patients in the group B,and 16 patients in the group C. The incidence of new metastases at T2 in the group C was higher than that in the groups A and B( P < 0. 01). Cox regression analysis showed that the HR of new metastases in the group B was 3. 374( P< 0. 05,95% CI: 1. 328-5. 047),which was 6. 731 in the group C( P < 0. 05,95% CI: 3. 121-14. 800). Conclusion Serum MK level has certain predictive value for new metastasis during 131Ⅰ ablation treatment for postoperative PTC patients.
