Preoperative neutrophil-to-lymphocyte ratio plus platelet-to-lymphocyte ratioin predicting survival for patients with stage Ⅰ-Ⅱgastric cancer

Background:The preoperative neutrophil-to-lymphocyte ratio(NLR) and the platelet-to-lymphocyte ratio(PLR) are associated with poor prognosis of gastric cancer.We aimed to determine whether the combination of NLR and PLR(NLR-PLR) could better predict survival of patients after curative resection for stage Ⅰ-Ⅱ gastric cancer.Methods:We collected data from the medical records of patients with stage Ⅰ-Ⅱ gastric cancer undergoing curative resection between December 2000 and November 2012 at the Sun Yat-sen Cancer Center.The preoperative NLRPLR was calculated as follows:patients with both elevated NLR(≥2.1) and PLR(≥ 120) were given a score of 2,and patients with only one or neither were given a score of 1 or 0,respectively.Results:Kaplan-Meier analysis and log-rank tests revealed significant differences in overall survival(OS) among patients with NLR-PLR scores of 0,1 and 2(P < 0.001).Multivariate analysis showed that OS was independently associated with the NLR-PLR score[hazard ratio(HR) = 1.51,95%confidence interval(CI) 1.02-2.24,P = 0.039]and TNM stage(HR = 1.36,95%CI 1.01-1.83,P= 0.041).However,other systemic inflammation-based prognostic scores,including the modified Glasgow prognostic score,the prognostic nutritional index,and the combination of platelet count and NLR,were not.In TNM stage-stratified analysis,the prognostic significance of NLR-PLR was maintained in patients with stage Ⅰ(P < 0.001) and stage Ⅱ cancers(P= 0.022).In addition,the area under the receiver operating characteristic curve for the NLR-PLR score was higher than those of other systemic inflammation-based prognostic scores(P = 0.001).Conclusion:The preoperative NLR-PLR score is a useful predictor of postoperative survival in the patients with stage l-ll gastric cancer and may help identify high-risk patients for rational therapy and timely follow-up.

The combined prognostic value of pretreatment neutrophil-to-lymphocyte ratio, lymphocyte-to-monocyte ratio, and platelet-to-lymphocyte ratio in stage IE/IIE extranodal natural killer/T-cell lymphoma

Objective This study aimed to explore the combined prognostic value of pretreatment neutrophil-tolymphocyte ratio(NLR), lymphocyte-to-monocyte ratio(LMR), and platelet-to-lymphocyte ratio(PLR) in newly diagnosed IE/IIE extranodal natural killer/T-cell lymphoma(ENKTL) treated with a P-Gemox regimen combined with radiotherapy or radiotherapy alone.Methods A total of 132 patients from 2009 to 2017 at the Sichuan Cancer Hospital were enrolled in the study. The cutoff values of NLR, LMR, and PLR using overall survival(OS) rate as an endpoint were obtained by the receiver operating curve. Results The cutoff value of NLR was 3.5. Patients with high NLR had significantly shorter progressionfree survival(PFS)(P < 0.001) and OS(P < 0.001) than those with low NLR. Similarly, the cutoff value of LMR was 3.0. The high LMR group had significantly longer PFS(P=0.001) and OS(P < 0.001) than the low LMR group. Similarly, the cutoff value of PLR was 191.7. The high PLR group was significantly associated with poor PFS(P < 0.001) and OS(P < 0.001) than the low PLR group. Furthermore, combining NLR, LMR, and PLR to build a new model to stratify patients into low-, intermediate-, intermediate-high-, and high-risk groups, there were also significant differences in PFS(P < 0.001) and OS(P < 0.001). The univariate analysis showed that presenting B symptoms, stage IIE, local tumor invasion, Eastern Cooperative Oncology Group score ≥ 2, elevated lactate dehydrogenase level, elevated NLR, decreased LMR, and elevated PLR were significantly associated with poor survival. The multivariate analysis demonstrated that PLR was an independent prognostic factor for both PFS(hazard ratio [HR]= 2.073, 95% confidence interval [CI]= 1.080–3.981, P = 0.028) and OS(HR = 2.127, 95% CI = 1.102–4.107, P = 0.025).Conclusion Elevated pretreatment PLR was a novel simple predictor of poor survival in patients with stage IE/IIE ENKTL. Combining NLR, LMR, and PLR could provide additional stratification.

Significances of Peripheral Inflammatory Cells and Neutrophil/Platelet-Lymphocyte Ratio in Breast Cancer after Resection

Introduction: Breast cancer had become top leading cause of death in Taiwan and endangered women’s health worldwide. Therefore, we try to invest the peripheral inflammatory cell counts and neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) from our routine practice for the predictor of prognosis of breast cancer after resection. Patients and Methods: There were 574 breast cancer patients accepted surgical resection and registered in Cancer Registry Center of our hospital. Patient’s basic profiles, peripheral neutophil, lymphocyte and platelet count were measured for study. The scales of NLR and PLR were derived from the lower and higher normal range in cell count from neutrophil, lymphocyte and platelet respectively. Therefore, the scales for NLR and PLR were ≤1.62, 1.63 - 2.57, ≥2.58 and ≤224, 225 - 253, ≥254 respectively for analysis. Results: Poor 5-yr survival rate was found if higher cell counts of neutrophil and platelet (p ≤ 0.05). Three scales of NLR were ≤1.62, 1.63 - 2.57, ≥2.58, and their 5-year survival rates were 94%, 91% and 84% respectively (p = 0.019). In the subgroup of HER-2 (negative), and 3-Negative breast patients had a higher NLR of poor prognosis. But higher PLR was found less in 3-Negative and non in 3-Positive patients (p = 0.039). The PLR was ≤224, 225 - 253, ≥254 and their 5-year survival rates were 92%, 87%, and 64% respectively (p = 0.001);Multivariate Cox regression model for predictor of breast cancer patients who have 3.39 (PLR ≥ 254) and 2.45 (NLR ≥ 2.58 ) times risk (p = 0.02 and p = 0.002) of poor prognosis respectively. Conclusion: Peripheral inflammatory cell counts are easily to take in our clinical practice and have a potential role as predictors of prognosis. We have to pay attention to the trends of peripheral inflammatory cell count and their ratio in our clinical practice where possible.

Preoperative Neutrophil Lymphocyte Ratio and Platelet Lymphocyte Ratio Cannot Predict Lymph Node Metastasis and Prognosis in Patients with Early Gastric Cancer:a Single Institution Investigation in China

In the present study,we aimed at exploring the applied value of preoperative neutrophil lymphocyte ratio(NLR)and platelet lymphocyte ratio(PLR)in the prediction of lymph node metastasis(LNM)and prognosis in patients with early gastric cancer(EGC).We retrospectively analyzed a total of 248 consecutive patients who underwent curative gastrectomy to be identified T1 stage gastric adenocarcinoma between January 1,2010 and May 1,2016 in a single institution.According to median preoperative NLR and PLR value,we divided the patients into four groups:high NLR≥1.73 and low NLR〈1.73,high PLR≥117.78 and low PLR〈117.78.Furthermore,to evaluate the relationship between preoperative NLR and PLR values,we categorized patients according to cutoff preoperative NLR-PLR score of 2[high NLR(≥1.73)and high PLR(≥117.78)],1[either high NLR or high PLR],and 0[neither high NLR nor high PLR].Statistical analyses were conducted using SPSS 20.0 software.The results showed that the preoperative NLR or PLR values,lower or higher,could not predict the LNM in patients with EGC(both P=0.5440.05).The invasive depth of tumor was significantly correlated with LNM of EGC(P〈0.001).Kaplan-Meier plots illustrated that preoperative NLR and PLR values were not associated with overall survival(OS)in patients with EGC.It was concluded that the preoperative NLR and PLR may be the predictors for LNM and prognosis in patients with advanced gastric cancer;nevertheless,they cannot predict LNM and prognosis in patients with EGC.

Prognostic value of neutrophil/lymphocyte,platelet/lymphocyte,lymphocyte/monocyte ratios and Glasgow prognostic score in osteosarcoma:A meta-analysis

BACKGROUND Some studies investigated the prognostic role of several blood biomarkers,including the neutrophil/lymphocyte ratio(NLR),platelet/lymphocyte ratio(PLR),lymphocyte/monocyte ratio(LMR)and Glasgow prognostic score(GPS),in osteosarcoma,but their results were inconsistent with each other.AIM To identify the prognostic value of NLR,PLR,LMR and GPS in osteosarcoma patients through reviewing relevant studies.METHODS The PubMed,EMBASE,Web of Science and CNKI databases were searched up to October 2,2021.The primary and second outcomes were overall survival(OS)and disease-free survival(DFS),respectively.The hazard ratios(HRs)with 95%confidence intervals(CIs)were combined to assess the association between these indicators and prognosis of osteosarcoma patients.RESULTS A total of 13 studies involving 2087 patients were eventually included.The pooled results demonstrated that higher NLR and GPS were significantly associated with poorer OS(HR=1.88,95%CI:1.38-2.55,P<0.001;HR=2.19,95%CI:1.64-2.94,P<0.001)and DFS(HR=1.67,95%CI:1.37-2.04,P<0.001;HR=2.50,95%CI:1.39-4.48,P<0.001).However,no significant relationship of PLR and LMR and OS(P=0.085;P=0.338)and DFS(P=0.396;P=0.124)was observed.CONCLUSION Higher NLR and GPS were related with worse prognosis and might serve as novel prognostic indicators for osteosarcoma patients.

Correlation of neutrophil/lymphocyte and platelet/lymphocyte ratio with visual acuity and macular thickness in age-related macular degeneration

AIM：To investigate the place of neutrophil-to-lymphocyte ratio（NLR） and platelet-to-lymphocyte ratio（PLR） in the diagnosis of and prognosis for neovascular age-related macular degeneration（AMD）. METHODS：One hundred AMD patients and 100 healthy controls were included in the study. Blood samples were obtained from the venous blood, which is used for routine analysis, and these samples were subjected to complete blood count. NLR was defined as the neutrophil count divided by the number of lymphocytes, and PLR was defined as the platelet count divided by the number of lymphocytes. RESULTS：No statistically significant difference was observed between the two groups under consideration in terms of demographic features（P〉0.05）. The average NLR in the patient group was found to be significantly higher than that in the healthy control group（P〈0.05）. The average PLR was significantly higher in the patient group as compared to the control group（P〈0.05）. As best corrected visual acuity（BCVA） increased, both NLR and PLR decreased（significant negative correlations at 49.8% and 63.0%, respectively）, whereas as central macular thickness（CMT） increased, both NLR and PLR increased（significant positive correlations at 59.3% and 70.0%, respectively）.CONCLUSION：NLR and PLR levels are higher among neovascular AMD patients as compared to healthy control group. NLR and PLR levels were found to be inversely proportional to BCVA and directly proportional to CMT.

Neutrophil Lymphocyte Ratio as an Inflammatory Marker in Chronic Kidney Disease: Determinants and Correlates

Introduction: Inflammation has been implicated as a major reason for the higher morbidity and mortality in chronic kidney disease (CKD) compared to the diseases that commonly precedes it. The neutrophil lymphocyte ratio (NLR) has increasingly been reported to be a marker of systemic inflammation. We studied the neutrophil lymphocyte ratio and its relationship with kidney function and other markers of inflammation in health and in CKD. Methods: Two hundred and forty four participants in three cohorts: healthy, CKD stage 1 - 2 and, stage 3 - 4, were studied. Data of clinical, NLR, uric acid, urine albumin creatinine ratio (UACR), electrolytes were documented and independent associates of NLR were determined. Results: The NLR was higher in the CKD cohorts, P Conclusion: The NLR as an inflammatory marker is elevated in chronic kidney disease, and increases with disease severity hence it can be a useful tool in determining the presence and severity of inflammation in CKD.

The prognostic value of lymphocyte-to-monocyte ratio in retinopathy of prematurity

AIM： To evaluate the associations between development of retinopathy of prematurity（ROP） and serum lymphocyteto-monocyte ratio（LMR）, neutrophil-to-lymphocyte ratio（NLR）, and platelet-to-lymphocyte ratio（PLR）. METHODS： A retrospective cohort study was performed, involving infants who were screened for ROP from January 2015 to December 2015. Preterm newborns of ≤32 gestational weeks with ROP were enrolled as the observation group, and non-ROP infants were enrolled as the control group, whose complete blood cell were measured within the first 24 h of life. The levels of NLR, LMR and PLR were determined in all groups. The data obtained were analyzed using univariate and multivariate logistic regression analysis.RESULTS： In this study, 40 cases of ROP were enrolled and 40 cases of non-ROP as controls. The LMR levels were significantly higher（P〈0.001） in ROP group（3.96±1.16） compared to non-ROP group（2.85±0.79）. The NLR levels were significantly lower（P=0.035） in ROP group {median [interquartile range（IQR）], 0.88（0.67-1.46）} compared to non-ROP group [median（IQR）, 1.20（0.85-1.89）]. The median PLR values were 61.99（IQR, 50.23-75.98） in ROP group and 69.24（IQR, 55.52-88.12） in non-ROP group（P=0.104）. Logistic regression analysis suggested that LMR was an independent risk factor for ROP（OR： 0.275; 95% CI： 0.134-0.564; P=0.001）. CONCLUSION： The findings demonstrate that higher LMR is independently and significantly associated with the development of ROP, and the LMR may be invoked as a predictive tool for identifying risk for ROP.
