摘要:

目的: 分析术后接受131I治疗的乳头状甲状腺微小癌(papillary thyroid microcarcinoma, PTMC)与乳头状甲状腺非微小癌(papillary thyroid non-microcarcinoma, non-PTMC)病人的临床病理特征,并比较治疗转归的差异,以期指导PTMC的131I治疗决策。方法: 纳入2015年1月至2020年12月在天津医科大学总医院核医学科131I治疗的1 118例PTC病人,采用卡方检验及秩和检验比较PTMC组与non-PTMC组病人临床病理特征、131I治疗情况及治疗反应的差异,Kaplan-Meier法绘制两组的治疗反应不佳(incomplete response, IR)率曲线。结果: PTMC组病人多灶性、累及双叶的比例均高于non-PTMC组,腺外侵犯、T4、N1b、刺激性甲状腺球蛋白(stimulated thyroglobulin, sTg)>10 μg/L及高危复发风险的比例低于non-PTMC组(P<0.05)。PTMC组多数病人首次接受清甲治疗,而non-PTMC组中更多病人接受辅助及清灶治疗(P<0.05)。两组病人131I治疗反应、疗效满意(excellent response, ER)率和IR率的差异均无统计学意义,IR率曲线差异也无统计学意义(P>0.05)。结论: PTMC具有一定的侵袭性。经综合评估和规范131I治疗后,PTMC和non-PTMC病人治疗转归大致相同。PTMC的界定对131I治疗决策的指导价值极其有限。

Abstract:

Objective To analyze the clinicopathological data of patients with papillary thyroid microcarcinoma (PTMC) and papillary thyroid non-microcarcinoma (non-PTMC) who received 131I therapy retrospectively, and compare the therapeutic response of the two groups of patients, so as to guide 131I therapy decisions for PTMC patients. Methods A total of 1 118 patients with papillary thyroid carcinoma (PTC) underwent 131I therapy in the Department of Nuclear Medicine, Tianjin Medical University General Hospital from January 2015 to December 2020 were enrolled. Chi-square test and Mann-Whitney U test were used to compare the differences of clinicopathological features and 131I therapy, therapeutic response between two groups. The incomplete response (IR)rate curves of the two groups were plotted by Kaplan-Meier analysis.Results The proportion of patients with multifocal, involvement of bilateral thyroid lobes in PTMC group were higher than those in non-PTMC group, and the proportion of patients with extra-thyroid extension, T4, N1b, stimulated thyroglobulin(sTg)>10 μg/L, and high risk stratified were lower than those in non-PTMC group (P<0.05). Most patients in PTMC group received remnant ablation for the first time, while more patients in non-PTMC group received adjuvant therapy and therapy for known disease (P<0.05). There was no statistically significant difference in 131I therapeutic response, the rates of excellent response(ER) and IR in two groups, and the differences in curves of IR rate between the two groups were also no statistically significance (P>0.05). Conclusions PTMC has a certain degree of invasiveness. As long as the patients were comprehensively evaluated and the standard 131I therapy was adopted, the treatment outcomes of patients with PTMC and non-PTMC were roughly the same. Therefore, the clinical value of the definition of PTMC is extremely limited in the formulation of 131I therapeutic dose regimens.
