摘要:

目的 探讨血清胸苷激酶1(TK1)在甲状腺乳头状癌(PTC)患者术后监测中的价值。方法 选取2020年7月—2021年3月陕西省人民医院PTC患者178例,根据治疗方式分为次全切组(53例,行甲状腺次全切术)、全切组(125例,行甲状腺全切术62例、行甲状腺全切术+131I治疗63例)。根据患者术后12个月的恢复情况将178例PTC患者分为疗效满意(ER)组(153例)和疗效不满意(NER)组(25例)。收集所有患者的临床资料,监测患者术前和术后1、3、6、12个月血清TK1、甲状腺球蛋白(Tg)水平。采用受试者工作特征(ROC)曲线评价血清TK1、Tg水平判断PTC患者预后不良的效能。采用二元Logistic回归分析评估PTC患者预后不良的危险因素。结果 ER组与NER组之间年龄、肿瘤多灶性、肿瘤最大直径、T分期、N分期、转移淋巴结数差异均有统计学意义(P<0.05),性别、被膜侵犯情况、治疗方式2个组之间差异均无统计学意义(P>0.05)。NER组术后各时间节点血清TK1水平均高于ER组(P<0.05)。次全切组和全切组NER患者术后6、12个月血清TK1水平均高于ER患者(P<0.05)。全切组NER患者术前和术后各时间点血清Tg水平均高于ER患者(P<0.05)。ROC曲线分析结果显示,术后12个月血清TK1水平判断次全切PTC患者预后不良的效能最高[曲线下面积(AUC)为0.940],其次为术后6个月血清TK1水平(AUC为0.835);术后12个月TK1和Tg联合检测判断全切PTC患者预后不良的AUC最高(0.964),其次为术后6个月TK1和Tg联合检测(AUC为0.943)。二元Logistic回归分析结果显示,T分期、术前Tg≥62.08 IU·L-1是PTC患者预后不良的危险因素[比值比(OR)值分别为5.060、2.908,95%可信区间(CI)分别为2.593~9.875、1.004~8.421,P<0.05]。结论 动态监测血清TK1有助于评估PTC患者次全切术后疗效,联合检测血清TK1、Tg水平有助于行全切术患者的预后评估。

Abstract:

Objective To investigate the application role of serum thymidine kinase 1(TK1) in postoperative monitoring of thyroid papillary carcinoma(PTC) patients. Methods A total of 178 patients with PTC in Shaanxi Provincial People's Hospital from July 2020 to March 2021 were enrolled,which included 53 cases in subtotal thyroidectomy group,62 cases in total thyroidectomy group and 63 cases in total thyroidectomy + 131I treatment group. According to the treatment efficiency after 12 months,the patients were classified into excellent response(ER) group(153 cases) and non-excellent response(NER)group(25 cases). The clinical data of patients were collected,and the levels of TK1 and thyroglobulin(Tg) were monitored before operation and after 1,3,6 and 12 months of operation. Receiver operating characteristic(ROC) curve was applied to evaluate the efficacy of TK1 and Tg at different times in predicting poor prognosis of PTC. The risk factors affecting the poor prognosis of PTC were analyzed by binary Logistic regression analysis. Results Between ER and NER groups,there was statistical significance for age,multifocality,maximum tumor diameter,T stage,N stage and the number of metastatic lymph nodes(P<0.05),and there was no statistical significance in sex,capsular invasion and treatment(P>0.05). Serum TK1 level in NER group was higher than that in ER group at all time points after operation(P<0.05). Serum TK1 levels in NER patients in subtotal thyroidectomy group and total thyroidectomy group were higher than those in ER patients at 6 months and 12 months after operation(P<0.05). The serum Tg level of NER patients in total thyroidectomy group was higher than that in ER patients at all time points before and after operation(P<0.05). ROC curve analysis showed that serum TK1 level at 12 months after operation had the highest efficacy in determining poor prognosis in patients with subtotal thyroidectomy,and the area under curve(AUC) was 0.940,followed by serum TK1 level at 6 months after operation(AUC was 0.835). TK1 and Tg combined determination had the highest AUC(0.964) at 12 months after operation,followed by TK1 and Tg combined determination at 6 months after operation(AUC was 0.943). Binary Logistic regression analysis showed that T stage and preoperative Tg≥62.08 IU·L-1were risk factors for poor prognosis in PTC patients [odds ratios(OR) were 5.060 and 2.908,95% confidence intervals(CI) were 2.593-9.875 and 1.004-8.421,respectively,P<0.05]. Conclusions Dynamic monitoring of TK1 can accurately evaluate the disease progression of patients undergoing subtotal thyroidectomy,the combined determination of TK1 and Tg levels can evaluate the prognosis of patients with total thyroidectomy.
