Abstract

BACKGROUND: The prognostic value of lymph node ratio (LNR) has been proved in several cancers. However, the potential of LNR to be a prognostic factor for thyroid cancer has not been validated so far. This article evaluated the prognostic value of LNR for thyroid cancer through a meta-analysis. METHODS: A systematic search was conducted for eligible publications that study the prognostic values of LNR for thyroid cancer in the databases of PubMed, EMBASE, Cochrane, and Web of Science up until October 24, 2023. The quality of the eligible studies was evaluated by The Newcastle-Ottawa Assessment Scale of Cohort Study. The effect measure for meta-analysis was Hazard Ratio (HR). Random effect model was used to calculate the pooled HR and 95% confidence intervals. A sensitivity analysis was applied to assess the stability of the results. Subgroup analysis and a meta-regression were performed to explore the source of heterogeneity. And a funnel plot, Begg's and Egger's tests were used to evaluate publication bias. RESULTS: A total of 15,698 patients with thyroid cancer from 24 eligible studies whose quality were relatively high were included. The pooled HR was 4.74 (95% CI:3.67-6.11; P<0.05) and a moderate heterogeneity was shown (I2 = 40.8%). The results of meta-analysis were stable according to the sensitivity analysis. Similar outcome were shown in subgroup analysis that higher LNR was associated with poorer disease-free survival (DFS). Results from meta-regression indicated that a combination of 5 factors including country, treatment, type of thyroid cancer, year and whether studies control factors in design or analysis were the origin of heterogeneity. CONCLUSION: Higher LNR was correlated to poorer disease free survival in thyroid cancer. LNR could be a potential prognostic indicator for thyroid cancer. More effort should be made to assess the potential of LNR to be included in the risk stratification systems for thyroid cancer.

摘要

背景:淋巴结比率(LNR)的预后价值已在多种癌症中得到证实。然而,LNR作为甲状腺癌预后因素的潜力迄今尚未得到验证。本文通过荟萃分析评估了LNR对甲状腺癌的预后价值。 方法:在PubMed、EMBASE、Cochrane和Web of Science数据库中进行系统检索,以查找截至2023年10月24日研究LNR对甲状腺癌预后价值的合格出版物。采用队列研究的纽卡斯尔-渥太华评估量表评估合格研究的质量。荟萃分析的效应量为风险比(HR)。采用随机效应模型计算合并HR及95%置信区间。应用敏感性分析评估结果的稳定性。进行亚组分析和荟萃回归以探索异质性来源。并使用漏斗图、Begg检验和Egger检验评估发表偏倚。 结果:共纳入24项质量相对较高的合格研究中的15698例甲状腺癌患者。合并HR为4.74(95%CI:3.67 - 6.11;P<0.05),显示出中度异质性(I² = 40.8%)。敏感性分析表明荟萃分析结果稳定。亚组分析显示类似结果,即较高的LNR与较差的无病生存期(DFS)相关。荟萃回归结果表明,国家、治疗、甲状腺癌类型、年份以及研究在设计或分析中是否控制因素这5个因素的组合是异质性的来源。 结论:较高的LNR与甲状腺癌较差的无病生存期相关。LNR可能是甲状腺癌的一个潜在预后指标。应进一步努力评估LNR纳入甲状腺癌风险分层系统的潜力。 系统评价注册:https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=477135,标识符CRD42023477135 。
