探讨甲状腺转移癌淋巴结直径及热消融治疗的有效性和安全性。检索多个数据库中有关热消融治疗甲状腺癌转移淋巴结的文献。根据转移淋巴结直径进行亚组分析。这些措施包括平均体积减少的汇总估计、总消失和复发的汇总比例以及总体并发症的汇总比例。共有 20 项研究，涉及 372 名患者和 620 个转移淋巴结。根据转移淋巴结的平均最大直径，将其分为三组：A组（≤10mm）、B组（10<直径≤20mm）、C组（>20mm）。研究结果显示，仅A组和B组的平均体积显着减小。从肿瘤消失的比例来看，A组的百分比最高，其次是B组，最后是C组。A组和B组的复发率相当。 B组，但略低于C组。此外，三组总体并发症发生率排序为：A组>C组>B组。总体而言，热消融是治疗甲状腺癌转移淋巴结的有效且安全的方法直径为 10-20mm。版权所有 © 2024 Elsevier Inc. 保留所有权利。

To explore the diameter of lymph nodes with metastatic thyroid carcinoma and the effectiveness and safety of thermal ablation.Several databases were searched for literature on the treatment of thyroid carcinoma metastatic lymph nodes by thermal ablation. A subgroup analysis was performed according to the diameter of the metastatic lymph nodes. The measures included pooled estimates of mean volume reduction, pooled proportions of total disappearance and recurrence, and the pooled proportions of overall complications.There were 20 studies with 372 patients and 620 metastatic lymph nodes included. Based on the average maximum diameter of the metastatic lymph nodes, they were divided into three groups: A (≤ 10 mm), B (10 < diameter ≤ 20 mm), and C (> 20 mm). The study results indicated a significant decrease in the average volume only in groups A and B. The ratio of tumor disappearance showed that group A had the highest percentage, followed by group B and then group C. The recurrence rates were comparable between groups A and B, but slightly lower than in group C. Moreover, the overall complication rates for the three groups were ranked as follows: group A > group C > group B.Overall, thermal ablation is an effective and safe treatment for thyroid cancer metastatic lymph nodes with diameters of 10-20mm.Copyright © 2024 Elsevier Inc.
