免疫检查点抑制剂对癌症患者甲状腺功能的影响

目的 探讨免疫检查点抑制剂（ICI）对癌症患者甲状腺功能的影响。方法 回顾性分析39例接受ICIs治疗的癌症患者，治疗期间监测患者甲状腺功能指标。结果 39例采用ICIs治疗的患者中，5例（12.8%）发生甲状腺功能减退，需要甲状腺激素替代治疗。甲状腺功能减退发生在治疗早期，平均发生时间为治疗第2周期。经左甲状腺素钠片治疗后，随访期间患者甲状腺功能未恢复。结论 ICIs可引起甲状腺功能减退，可能发生在治疗早期，建议使用ICIs期间密切监测患者的甲状腺功能。

The impact of immune checkpoint inhibitors on thyroid function of cancer patients

Objective To investigate the effects of immune checkpoint inhibitors (ICIs) on the thyroid function of cancer patients.Methods Thirty-nine cancer patients with ICIs treatment were retrospectively analyzed in this study. All patients had their thyroid function indexes monitored during treatment.Results Of the 39 patients treated with ICIs, 5 cases (12.8%) had hypothyroidism and required thyroid hormone replacement therapy. Hypothyroidism occurred early at the ICIs treatment, with an average time at the second cycle. No evident recovery of thyroid function was observed during the follow up after treatment with levothyroxine sodium tablets.Conclusion Immune checkpoint inhibitors may cause hypothyroidism with early onset. Monitoring thyroid function is recommended during the use of immune checkpoint inhibitors.
