摘要

背景:以往对固定剂量放射性碘疗法(RIT)治疗巴塞杜氏病(GD)的研究采用了多种技术,并报告了不同的成功率。本研究旨在比较两种固定剂量方案的 RIT 疗效,并估算治疗 GD 的最佳放射性碘 (RAI) 活性:这项回顾性试验招募了 658 名在 2014 年 1 月至 2021 年 12 月期间接受 RIT 治疗的 GD 患者。参与者分为两组:方案 1 采用甲状腺大小特异性 RAI 剂量,方案 2 采用修改后的剂量计算方法。主要评估结果是随访6个月时是否出现甲状腺功能亢进或甲状腺功能减退。对两种方案的RIT成功率进行了比较:方案2的RIT成功率略低于方案1(63.6%对67.2%);但两组的治疗失败风险差异不大(相对风险,1.1089;95%置信区间,0.8937对1.3758;P=0.3477)。方案2的RAI活性中位数低于方案1(10.7 mCi vs. 15.0 mCi,P=0.0079),方案2组的甲状腺功能减退症发生率显著降低(39.0% vs. 48.9%,P=0.0117):结论:改良剂量计算方案的成功率与甲状腺大小特异性 RAI 剂量方案相当。前者降低了 RAI 活性,减少了 RIT 后甲状腺功能减退症的发生率,但并不影响成功率。

Comparison of Thyroid Size-Specific Radioiodine Dose and New Modified Dose Calculation in the Treatment of Graves' Disease.

Backgruound: Previous studies of fixed-dose radioiodine therapy (RIT) for Graves' disease (GD) have utilized a variety of techniques and reported differing success rates. This study sought to compare the efficacy of RIT using two fixed-dose protocols and to estimate the optimal radioiodine (RAI) activity for the treatment of GD.

Methods: This retrospective trial enrolled 658 patients with GD who received RIT between January 2014 and December 2021. Participants were divided into two groups: protocol 1, which utilized a thyroid size-specific RAI dose, and protocol 2, which employed a modified dose calculation approach. The primary outcome assessed was the presence of euthyroidism or hypothyroidism at the 6-month follow-up. The success rates of RIT were compared between the two protocols.

Results: The RIT success rate was marginally lower for protocol 2 than for protocol 1 (63.6% vs. 67.2%); however, the risk of treatment failure did not differ considerably between the groups (relative risk, 1.1089; 95% confidence interval, 0.8937 to 1.3758; P=0.3477). The median RAI activity associated with protocol 2 was lower than that for protocol 1 (10.7 mCi vs. 15.0 mCi, P=0.0079), and the frequency of hypothyroidism was significantly lower in the protocol 2 group (39.0% vs. 48.9%, P=0.0117).

Conclusion: The success rate of the modified dose calculation protocol was comparable to that of the thyroid size-specific RAI dose protocol. The former approach reduced RAI activity and the incidence of hypothyroidism following RIT without compromising the success rate.
