目的 探讨血小板相关参数中血小板计数（PLT）、血小板平均体积（MPV）、血小板/淋巴细胞比值（PLR）与不同类型突发性聋（SSNHL）发病的关系及对预后的影响。方法 121例SSNHL患者分为4组,其中低频下降型38例,高频下降型20例,平坦下降型31例,全聋型32例。同时根据疗效判定又将不同类型的SSNHL患者分别分为改善和未改善。并收集相同时期121例健康人作为对照组。比较SSNHL患者PLT、MPV、淋巴细胞绝对值、PLR与对照组的差异、不同类型SSNHL患者之间的差异及不同类型SSNHL患者治疗后改善与未改善患者之间的差异。结果 SSNHL患者与对照组间PLT、淋巴细胞绝对值、PLR比较,差异均具有统计学意义（P均<0.05）。不同类型SSNHL患者组间参数比较, PLR差异具有统计学意义（P<0.05）。不同类型SSNHL患者治疗改善与未改善参数比较,PLT、MPV、淋巴细胞绝对值、PLR差异均无统计学意义（P均>0.05）。结论 SSNHL患者PLT及PLR高于对照组,提示血小板在SSNHL的发病机制中起重要作用,炎症也可能是SSNHL发病的重要因素。但不同类型SSNHL的预后与PLT、MPV、PLR无关。     

外周血中性粒细胞与淋巴细胞比率及血小板与淋巴细胞比率对喉鳞状细胞癌预后价值的研究进展

喉鳞状细胞癌（LSCC）是头颈鳞状细胞癌最常见类型之一,由多种致癌因素共同影响所致且预后欠佳。LSCC预后因素包括个体状况、原发肿瘤大小、淋巴结受累情况、有无远处转移和人乳头状瘤病毒（HPV）感染等,均不能准确评估LSCC预后,因此,探寻新的指标显得尤为重要。在肿瘤的发生、发展、转移过程中,炎症因子起到了至关重要的作用,其中外周血中性粒细胞/淋巴细胞比率（NLR）、血小板/淋巴细胞比率（PLR）对LSCC预后价值较高且备受关注,因此本文将探讨NLR、PLR与LSCC预后价值的关系,为临床诊疗提供参考。     

术前血小板淋巴细胞比值对喉癌患者预后评估的临床意义

目的　探讨术前外周血血小板和淋巴细胞比值（PLR）对喉癌患者预后的影响。方法　回顾分析286例喉癌患者的临床资料，确定PLR以死亡为终点的最佳临界值，分析PLR高低与影响喉癌患者术后5年生存率的相关因素之间的关系。分析在众多可能影响喉癌患者术后5年生存率的相关因素中PLR是否为独立影响因素。结果　确定以死亡为终点的PLR的最佳临界值为149.9，将患者分为高PLR组（PLR≥149.9）与低PLR组（PLR<149.9）。NLR的高低与患者年龄、性别、病理分化程度不相关，与T分级、颈部淋巴结转移情况以及肿瘤的原发部位相关。经单因素及多因素分析，T分级、颈淋巴结转移、肿瘤原发部位、术前PLR高低是影响喉癌术后5年生存率的独立因素。结论　术前PLR水平是喉癌患者术后5年生存率的影响因素，对喉癌患者预后的评估具有重要意义。

The neutrophil-to-lymphocyte ratio in children with sudden sensorineural hearing loss: a retrospective study

Conclusion: The elevated neutrophil-to-lymphocyte ratio (NLR) value in children with sudden sensorineural hearing loss (SSNHL) would suggest the inflammatory etiology of pediatric SSNHL. The results of this study may suggest NLR value can be used as a useful indicator, which is associated with the disease severity in pediatric SSNHL.

Objectives: This study aimed to elucidate any clues of inflammatory etiology, which might be related with the development of pediatric SSNHL, using calculated NLR.

Methods: Forty-six patients aged younger than 19 years, who were admitted to the hospital with the diagnosis of SSNHL, were included in the study. Forty-six healthy children were matched as control group according to their propensity score. The complete blood cell count, calculated NLR, platelet-to-lymphocyte ratio (PLR), and mean platelet volume (MPV) were compared. The relationship between NLR and the initial hearing level was also investigated.

Results: The mean NLR value was 2.86?±?2.58 in the SSNHL group, whereas the mean NLR value was 1.63?±?0.87 in the control group. The mean NLR value of the SSNHL children was significantly higher than that of the control group (p?=?.023). There was a positive correlation between the NLR value and initial hearing level (r?=?.312, p?=?.037).     

Pretreatment lymphocyte-to-monocyte ratio as an independent prognostic factor for hypopharyngeal squamous cell carcinoma

Objective: The aim of this work was to analyze the clinical characteristics and pretreatment peripheral blood cell counts of patients with hypopharyngeal squamous cell carcinoma (HPSCC) and determine their relationship with clinical outcomes.

Methods: One hundred ninety-seven patients were eligible for the study. The relationship between survival and pretreatment peripheral absolute neutrophil count (ANC), absolute lymphocyte count (ALC), absolute monocyte count (AMC), neutrophil-to-lymphocyte ratio (NLR), and lymphocyte-to-monocyte ratio (LMR) were analyzed by one-way analysis of variance, t-test, and univariate and multivariate analysis.

Results: The median follow-up time was 30.95 months (range 1–82 months). The 3-year disease-free survival (DFS), cancer-specific survival (CSS), and overall survival (OS) rates for all patients were 40.8, 51.0, and 48.1%, respectively. The ANC, AMC, NLR, and LMR were significantly associated with tumor stage and clinical stage (p?p?=?.035, .047, and .045, respectively).

Conclusion: The pretreatment LMR should be considered as an independent prognostic factor for patients with HPSCC.     

Neutrophil-lymphocyte ratio and platelet-lymphocyte ratio as predictors of wound healing failure in head and neck reconstruction

Conclusions: In microsurgical head and neck reconstruction, a higher rate of post-operative wound complication could be predicted by a lower pre-operative neutrophil ratio (Objectives: To evaluate the predictor of post-operative wound complications in microsurgical head and neck reconstruction.

Methods: Patients who were undergoing tumor ablation and microsurgical reconstruction from April 2011 to March 2014 were analyzed retrospectively. The pre-operative hematological data, age, sex, co-morbidities, body mass index (BMI), adjuvant therapies, smoking, operation time, blood loss, total protein, T-stage, and Anesthesiologists Performance Status (ASA-PS) score were collected. Cases of post-operative wound healing failure were reviewed.

Results: One hundred and three consecutive patients were enrolled. Among these, the results of 77 patients who were younger than 70 years of age were analyzed. The distributions of the neutrophil ratio (p?=?.0005), lymphocyte ratio (p?=?.0166), monocyte ratio (p?=?.0341), NLR (p?=?.005), and PLR (p?=?.008) differed significantly between the patients with and without post-operative wound healing failure. Neutrophil ratio, NLR, and PLR cut-off values of 64.9, 3.5, and 160 were significantly associated with the rate of wound healing failure rate (p?=?.0002, .00021, .0042, respectively).     

The prognostic value of preoperative derived neutrophil-to-lymphocyte ratio in patients undergoing total laryngectomy with laryngeal carcinoma

Background: Emerging evidence indicate that inflammation plays a crucial role in carcinogenesis and tumor progression. Inflammatory response biomarkers are recognized as promising prognostic factors in laryngeal squamous cell carcinoma (LSCC).

Objective: To evaluate the prognostic significance of preoperative derived neutrophil-to-lymphocyte ratio (dNLR) in patients with total laryngectomy.

Methods: This was a retrospective analysis of 137 patients with LSCC who received total laryngectomy from January 2009 to December 2015. The preoperative neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and dNLR were calculated. Receiver-operating characteristic (ROC) curve was used to determine the cut-off values of these parameters. Univariate analysis and multivariate Cox regression model were used to evaluate the association between these parameters and recurrence-free survival (RFS) and overall survival (OS).

Results: The optimal critical value of dNLR was 1.85, by which cases were divided into high dNLR group (dNLR ≥ 1.85) and low dNLR group (dNLR?<?1.85). The elevated dNLR was significantly associated with decreased RFS (HR 2.72, 95% CI 1.56–4.75, p?=?.000) and remained significant in multivariate analysis (p?=?.034). However, we did not find any significant correlation between dNLR and OS.

Conclusions: An elevated preoperative dNLR may be an independent prognostic biomarker for RFS in patients undergoing total laryngectomy with LSCC.     

Prognostic role of neutrophil lymphocyte ratio and mean platelet volume in Bell’s palsy: Comparison of diabetic and non-diabetic patients

ObjectivesA low Neutrophil Lymphocyte Ratio (NLR) has been shown to be associated with good prognosis in Bell’s Palsy (BP). However, the effect of chronic diseases that may affect the NLR, including Diabetes Mellitus (DM), has not been clarified in this context. This study aimed to evaluate the relationship between NLR and Mean Platelet Volume (MPV) in BP according to whether it is accompanied by DM, and their relationship with prognosis.MethodsA prospective observational study was conducted from May 2014 to May 2020 in a tertiary referral center, of all 79 consecutive participants diagnosed with BP in department of otolaryngology and 110 consecutive healthy participants admitted to the check-up unit. Patients diagnosed with BP were divided into two groups according to whether they were diagnosed with DM: diabetic BP patients (DM-BP, n = 33) and non-diabetic BP patients without any chronic disease (nonDM-BP, n = 46). Neutrophil (NEUT) and Lymphocyte (LYM) counts, and Mean Platelet Volume (MPV) were assessed from peripheral blood samples, and the NLR was calculated. Prognosis was evaluated using the House–Brackmann Score (HBS) six months after diagnosis.ResultsThe mean NLR was 2.85 ± 1.85 in BP patients and 1.69 ± 0.65 in the control group. The mean NLR was significantly higher in BP patients than healthy controls (p < 0.001). The mean NLR was 2.58 ± 1.83 in the nonDM-BP group, 3.23 ± 1.83 in the DM-BP group, and 1.69 ± 0.65 in the control group. The NLR was significantly higher in the nonDM-BP and DM-BP groups than in the control group (p < 0.05). The recovery was 90% according to the HBS. The optimal cut-off value was 2.41 (p = 0.5).ConclusionThe NLR was increased in both diabetic and non-diabetic BP and had similar prognostic value in predicting the HBS before treatment in diabetic and non-diabetic patients with BP. MPV wasn’t significantly different in diabetic and non-diabetic BP patients compared with the normal population.     

Association between routine hematological parameters and sudden sensorineural hearing loss: A meta-analysis

Objective:Recent studies have shown that chronic inflammation contributes to the development of sudden sensorineural hearing loss(SSNHL).Some hematologic parameters have also been linked to the prognosis of SSNHL.However,the prognostic value of such hematological factors is not conclusive.This study explored the association of routine hematological parameters with SSNHL.Methods:A systematic literature search was conducted in PubMed,Cochrane Library,Web of Science and Embase to identify eligible studies.Standardized mean deviation(SMD)and the 95%confidence interval(CI)were retried from relevant studies for analysis.Heterogeneity,subgroup,and publication bias analyses were performed.Results:A total of 18 studies involving 1505 SSNHL patients and 1466 healthy persons were enrolled in the final analysis.The study population included 699 responders and 458 non-responders to treatment.Pooled results revealed that the neutrophil/lymphocyte ratio(NLR)and platelet/lymphocyte ratio(PLR)value in the SSNHL patient group were higher than in the healthy group(SMD=1.05,95%CI:0.86,1.24,p<0.001,SMD=0.52,95%CI:0.26,0.78,p<0.001,respectively).However,there was no significant difference in the mean platelet volumes(MPV)between the groups(SMD=0.03,95%CI:0.44,0.49,p=0.91).Notably,NLR and PLR values were evidently higher in the unrecovered group than in the recovered group(SMD=0.63,95%CI:1.02,0.23,p=0.002,SMD=0.4,95%CI:0.76,0.03,p=0.03,respectively).However,the MPV value was similar in both groups(SMD=0.35,95%CI:1.14,0.44,p=0.38).Conclusions:Our results show that NLR and PLR values can predict the onset and prognosis of SSNHL.
