术前中性粒细胞与淋巴细胞比值和血小板与淋巴细胞比值与CRS术后复发的相关性分析

The correlation between preoperative neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio and postoperative recurrence of chronic rhinosinusitis

目的:探讨术前中性粒细胞与淋巴细胞比值(neutrophil-to-lymphocyte ratio,NLR)和血小板与淋巴细胞比值(platelet-to-lymphocyte ratio,PLR)与慢性鼻窦炎(CRS)术后复发风险的相关性。方法:收集2018年10月-2022年2月在河南大学淮河医院耳鼻咽喉头颈外科初次行功能性内镜鼻窦手术的CRS患者临床资料。随访至2023年2月,研究终点定义为患者术后复发或随访时间截止。根据受试者工作曲线分析获得术前NLR和PLR最佳临界值,分别将其分为高、低水平亚组,并比较组间患者的临床特征及术后复发率;根据患者术后复发情况将患者分为未复发CRS和复发CRS,采用Kaplan-Meier生存曲线和logistic回归分析探讨NLR和PLR与CRS术后复发的相关性。结果:共纳入630例CRS患者,其中高NLR组382例,高PLR组140例。高NLR组和高PLR组CRS患者的术后复发率分别显著高于低NLR组和低PLR组,差异有统计学意义(P<0.05)。复发CRS的NLR、PLR水平和高NLR、高PLR比例均高于未复发CRS,差异有统计学意义(P<0.05),同样复发CRS的病程和变应性鼻炎(AR)伴发率均显著高于未复发CRS,差异有统计学意义(P<0.05)。Kaplan-Meier生存曲线显示,高NLR组和高PLR组CRS较低NLR组和低PLR组术后复发率显著上升,差异有统计学意义(P<0.05)。此外,logistic回归分析显示,高NLR组、高PLR组的病程和合并AR与CRS术后复发风险增加显著相关,差异有统计学意义(P<0.05)。结论:术前高NLR和高PLR均是CRS术后复发的独立危险因素,其有望成为CRS患者术后预后评估和风险分层的新指标。此外,病程和合并AR与CRS术后复发风险显著相关。

Objective:Neutrophil-to-lymphocyte ratio(NLR) and platelet-to-lymphocyte ratio(PLR) play important roles in the poor prognosis of different inflammatory and neoplastic diseases,but their effects on postoperative recurrence of chronic rhinosinusitis(CRS) are unknown.The aim of this study was to investigate the correlation between preoperative NLR and PLR and the risk of postoperative recurrence in CRS.Methods:Clinical data were collected from patients with CRS who underwent initial functional endoscopic sinus surgery from October 2018 to February 2022 at our institution.Follow-up was until February 2023,and the study endpoint was defined as patient postoperative recurrence or follow-up time up to date.The optimal preoperative NLR and PLR threshold values were obtained based on subject work curve analysis,and they were divided into high and low level subgroups,respectively,and the clinical characteristics and postoperative recurrence rates of patients were compared between groups;patients were divided into non-recurrent CRS and recurrent CRS according to their postoperative recurrence,and Kaplan-Meier survival curves and logistic regression analysis were performed to explore the correlation between NLR and PLR and CRS The correlation between NLR and PLR and postoperative recurrence was investigated by Kaplan-Meier survival curve and logistic regression analysis.Results:A total of 630 patients with CRS were included,including 382 and 140 patients with high NLR and high PLR,respectively.The postoperative recurrence rates of CRS patients in the high NLR and high PLR groups were significantly higher than those in the low NLR and low PLR groups(P<0.05).The recurrent CRS had higher NLR and PLR levels and higher proportion of high NLR and high PLR than the non-recurrent CRS(P<0.05),and similarly the duration of recurrent CRS and the rate of allergic rhinitis with recurrence were significantly higher than the non-recurrent CRS(P<0.05).Kaplan-Meier survival curves showed that postoperative CRS was significantly higher in the high NLR and high PLR groups compared with the low NLR and low PLR groups.recurrence was significantly higher(P<0.05).In addition,logistic regression analysis showed that high NLR,high PLR,disease duration,and combined allergic rhinitis were significantly associated with an increased risk of postoperative recurrence of CRS(P<0.05).Conclusion:Both high preoperative NLR and high PLR are independent risk factors for postoperative recurrence of CRS,and they are expected to be new indicators for postoperative prognostic assessment and risk stratification of CRS patients.In addition,disease duration and comorbid allergic rhinitis were significantly associated with the risk of postoperative recurrence of CRS.
