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.

Significance of the preoperative neutrophil-to-lymphocyte ratio in the prognosis of patients with gastric cancer

AIM: To investigate the significance of the preoperative neutrophil-to-lymphocyte ratio(NLR) in the prognosis of patients with gastric cancer(GC). METHODS: The clinical data of 291 GC patients were analysed retrospectively; these patients were divided into two groups according to their preoperative NLR: a high-NLR group(NLR ≥ 3.5, 131 cases) and a low-NLR group(NLR < 3.5, 160 cases). The clinicopathological characteristics and five-year survival rates of the two groups were compared. The NLR and other clinicopathological factors were subjected to univariate and multivariate survival analysis to evaluate the effects of the NLR on the prognosis of GC patients. RESULTS: The lowest preoperative NLR among the 291 patients was 0.56, whereas the highest preoperative NLR was 74.5. The mean preoperative NLR was 5.99 ± 8.98. Age, tumour size, T staging, tumour-node-metastasis(TNM) staging and platelet count were significantly different between the highand low-NLR groups(P < 0.05). The five-year survival rate of the high-NLR group was 17.0%, which was significantly lower than that of the low-NLR group(43.6%; 17.0% vs 43.6%, P < 0.05). The univariate analysis results showed that the five-year survival rate was related to age, tumour size, T staging, N staging, TNM staging, carcinoembryonic antigen value and NLR(P < 0.05). Multivariate analysis results showed that the NLR was an independent risk factor that likely affected the five-year survival rate of GC patients(P = 0.003, HR = 0.626, 95%CI: 0.460-0.852). CONCLUSION: The preoperative NLR could be used as a prognostic factor for GC patients; in particular, a high NLR corresponded to poor prognosis of GC patients.

Hemoglobin, albumin, lymphocyte, and platelet score as a predictor of prognosis in metastatic gastric cancer

BACKGROUND The hemoglobin,albumin,lymphocyte,and platelet(HALP)score,derived from a composite evaluation of markers reflecting the tumor-inflammation relationship and nutritional status,has been substantiated as a noteworthy prognostic determinant for diverse malignancies.AIM To investigate how the HALP score relates to prognosis in patients with metastatic gastric cancer.METHODS The cutoff values for the HALP score,neutrophil/lymphocyte ratio,and platelet/lymphocyte ratio were determined using receiver operating characteristic analysis.Low HALP scores were defined as those less than 24.79 and high HALP scores as those greater than 24.79.RESULTS The study cohort comprised 147 patients and 110 of them(74.8%)were male.The patients'median age was 63(22-89)years.The median overall survival was significantly superior in the patients with high HALP scores than in those with low HALP scores(10.4 mo vs 7.5 mo,respectively;P<0.001)CONCLUSION The HALP score was found to be a prognostic factor in patients with metastatic gastric cancer.

Role of Pre-Operative of Neutrophil/Lymphocyte and Platelet/Lymphocyte Ratio in Prognosis of Hepatocellular Carcinoma

Introduction: Hepatocellular carcinoma (HCC) has a poor prognosis and is ranked in the top 2 leading causes of death in Taiwan. The clinical features which affect survival rate should be noticed for alarming. We tried to study the neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) for the predictor of prognosis of HCC. Patients and Methods: A total of 525 patients with HCC were undergone surgical or non-surgical treatment registered in Cancer Registry Center of our hospital. The clinical features included patient’s basic profiles, and neutrophil, lymphocyte and platelet count in the peripheral blood at the time of diagnosis. The ratio of neutrophil/lymphocyte and platelate/lymphocyte was measured and their survival rates were analyzed based on their ratio scales. Results: Three scales of NLR and PLR were ≤1.62, 1.63 - 2.57, ≥2.58 and ≤224, 225 - 253, ≥254 respectively. Either higher NLR ≥ 2.58 or higher PLR ≥ 254 was found mostly in the male and TMN stage III and IV with a significant difference (P < 0.01). The 5-year survival rates of NLR ≤ 1.62, 1.63 - 2.57, ≥2.58 were 33.9%, 33.7%, and 16.7% respectively (P < 0.001). The mean survival times were 34.1 ± 1.4, 29.3 ± 8.1, and 14.2 ± 2.1 months for the scales of PLR ≤ 224, 225 - 253, and ≥ 254 respectively. The 5-year survival rates were 25.5%, 36.4%, and 7.7% for the groups of the PLR ≤ 224, 225 - 253, and ≥254 respectively (p < 0.001). Conclusion: Neutrophil, lymphocyte and platelet are players in cancer growth and have a potential role as predictors of survival in our HCC patients. Therefore, we should pay more attention to the higher NLR or PLR which will result in a poorer prognosis in our patients.

Correlation between epithelial ovarian cancer and thrombocytosis

Objective： To evaluate the clinical significance of platelet （PLT） count in epithelial ovarian cancer, and to investigate the correlation between thrombocytosis and the incidence of epithelial ovarian cancer. Methods： We evaluated 220 epithelial ovarian tumor patients divided into early stage epithelial ovarian cancer group （n = 80）, advanced stage epithelial ovarian cancer group （n = 50） and benign ovarian tumor group （n = 90） as controls, who underwent primary surgical treatment. Three groups were evaluated with the relationship between platelet counts and preoperative and postoperative CA125, histopathology, abdominal edema, residual tumor, and lymph node metastasis. Epithelial ovarian cancer patients were evaluated whether platelet count was decreased after surgery. Results： The mean platelet counts were （234.55 ± 71.51）× 10^9/L in the early stage epithelial ovarian cancer group, （308.12±111.95）× 10^9/L in the advanced stage epithelial ovarian cancer group, and （206.28± 52.62） × 10^9/L in the benign ovarian tumor group, with a significant difference among the 3 groups （P 〈 0.05）. In the early stage epithelial ovarian cancer group, the platelet count was correlated with histopathology. In the advanced stage epithelial ovarian cancer group, there was a correlation between thrombocytosis and the incidence of that residual tumor diameter was greater than 2 cm. But there was no relationship between platelet count and histopathology, CA125, abdominal edema, or lymph node metastasis. In general the platelet count was decreased after surgery. Conclusion： An increased platelet count is commonly seen in patients with epithelial ovarian cancer, but it usually decreases after surgery. Patients with thrombocytosis have poor prognosis. Platelet count can be used as a marker for the development and prognosis of epithelial ovarian cancer.

Inflammation-based factors and prognosis in patients with colorectal cancer

Several parameters for predicting survival in patients with colorectal cancer have been identified, including the performance status, age, gender and tumor-nodemetastasis(TNM) stage. Although the TNM stage is important and useful for predicting the prognosis and determining the appropriate treatment, it is well known that the survival time varies widely, even in patients with the same stage of disease. Therefore, the identification of new parameters capable of more precisely predicting patient survival is needed to help select the optimal treatment, especially in patients in the advanced stage of disease. Although the TNM stage reflects the tumor characteristics, cancer progression and survival are not determined solely based on the local characteristics of the tumor, but also the host systemic immune/inflammatory response. Therefore, using a combination of parameters that reflect both tumor characteristics and the host systemic inflammatory status is thought to be important for accurately predicting patient survival.

Value of Preoperative Hematological Parameters in the Prognosis of Gastric Cancer Patients Undergoing a Total Gastrectomy

Objective This study aimed to evaluate the relationships between the albumin/globulin ratio(AGR),neutrophil/lymphocyte ratio(NLR),and platelet/lymphocyte ratio(PLR)and clinicopathological information for gastric cancer patients.In addition,the prognostic values of these hematological parameters for resectable gastric cancer patients undergoing a total gastrectomy were determined.Methods A total of 245 patients with gastric cancer who underwent a total gastrectomy at our hospital between January 1,2005,and December 30,2015,were enrolled into this study.The preoperative AGR,NLR,and PLR in the serum samples of the patients were measured.The relationships between the hematological parameters and the disease-free survival(DFS)as well as overall survival(OS)were analyzed by statistical analysis.Results The cutoff values of AGR,NLR,and PLR were 1.57,3.5,and 193,respectively.Univariate analyses demonstrated that a low AGR,a high NLR,and a high PLR were significant risk factors for a poor prognosis.According to multivariate analysis,a high PLR was found to be independently associated with a poor survival.Additionally,when age was considered as a stratified factor,univariate analyses demonstrated that a low AGR had the tendency to be correlated with a shorter DFS in nonelderly patients(<65 years old).A low AGR was significantly correlated with a shorter DFS and OS in elderly patients(≥65 years old).Conclusion AGR,NLR,and PLR are independent risk factors associated with a poor gastric cancer survival by univariate analysis,and AGR is an independent risk factor for predicting DFS and OS in elderly patients(≥65 years old)with gastric cancer after total gastrectomy.

Correlation analysis of CRP/ALB and P-CRP in the prognosis of non-small cell lung cancer

Objective:The purpose of this study was to investigate the relationship between preoperative C-reactive protein/albumin ratio(CRP/ALB),platelet count and C-reactive protein product(P-CRP)and clinical prognosis in patients with non-small cell lung cancer.Methods:From January 2015 to December 2015,284 patients who underwent surgery for lung cancer in the First Affiliated Hospital of Bengbu Medical College were selected.According to their 3-year and 5-year survival conditions,ROC curves were drawn and the best cut-off value was determined.According to the cut-off value,the patients were divided into high CRP/ALB group,low CRP/ALB group,high P-CRP group and low P-CRP group.Survival curves were described by Kaplan-Meier method and compared by Log-rank test.The univariate and multivariate analyses were performed with the Cox proportional hazard model to evaluate the prognostic factors.Results:Survival analysis showed that there was no significant difference in 3-year survival rate between high CRP/ALB and P-CRP groups and low CRP/ALB and P-CRP groups,while the 5-year survival rate in high CRP/ALB and P-CRP groups was significantly lower than that in low CRP/ALB and P-CRP groups.Cox proportional hazard model showed that CRP/ALB,age,smoking history,lymph node metastasis and TNM stage were risk factors for 5-year survival rate.Conclusion:as a prognostic index based on inflammation,preoperative CRP/ALB level can better reflect the prognosis of patients than P-CRP.

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.

Prognostic significance of the neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio in patients with stage Ⅲ and Ⅳcolorectal cancer

AIM To evaluate the prognostic value of the neutrophil-tolymphocyte ratio(NLR) and platelet-to-lymphocyte ratio(PLR) in patients with colorectal cancer(CRC).METHODS Between April 1996 and December 2010, medical records from a total of 1868 patients with CRC were retrospectively reviewed. The values of simple inflammatory markers including NLR and PLR in predicting the long-term outcomes of these patients were evaluated using Kaplan-Meier curves and Cox regression models.RESULTS The median follow-up duration was 46 mo(interquartile range, 22-73). The estimation of NLR and PLR was based on the time of diagnosis. In multivariate Cox regression analysis, high NLR (≥ 3.0) and high PLR(≥ 160) were independent risk factors predicting poor long-term outcomes in patients with stage Ⅲ and Ⅳ CRC. However, high NLR and high PLR were not prognostic factors in patients with stage Ⅰ and Ⅱ CRC.CONCLUSION In this study, we identified that high NLR (≥ 3.0) and high PLR (≥ 160) are useful prognostic factors to predict long-term outcomes in patients with stage Ⅲ and Ⅳ CRC.

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.

Platelet-to-lymphocyte ratio in the setting of liver transplantation for hepatocellular cancer: A systematic review and meta-analysis

AIM To perform a systematic review and meta-analysis on platelet-to-lymphocyte ratio(PLR) as a risk factor for post-transplant hepatocellular cancer(HCC) recurrence. METHODS A systematic literature search was performed using PubM ed. Participants of any age and sex, who underwent liver transplantation for HCC were considered following these criteria:(1) studies comparing pre-transplant low vs high PLR values;(2) studies reporting post-transplant recurrence rates; and(3) if more than one study was reported by the same institute, only the most recent was included. The primary outcome measure was set for HCC recurrence after transplantation. RESULTS A total of 5 articles, published between 2014 and 2017, fulfilled the selection criteria. As for the quality of the reported studies, all the investigated articles presented an overall high quality. A total of 899 cases were investigated: 718 cases(80.0%) were males. Three studies coming from European countries and one from Japan presented HCV as the main cause of cirrhosis. On the opposite, one Chinese study presented a greater incidence of HBV-related cirrhotic cases. In all the studies apart one, the PLR cut-off value of 150 was reported. At meta-analysis, high PLR value was associated with a significant increase in recurrence after transplantation(OR = 3.33; 95%CI: 1.78-6.25; P < 0.001). A moderate heterogeneity was observed among the identified studies according to the Higgins I^2 statistic value.CONCLUSION Pre-transplant high PLR values are connected with an increased risk of post-operative recurrence of hepatocellular cancer. More studies are needed for better clarify the biological mechanisms of this results.

Combined preoperative platelet-to-lymphocyte ratio and serum carbohydrate antigen 19–9 level as a prognostic factor in patients with resected pancreatic cancer

Background: Carbohydrate antigen 19–9(CA19-9) is the most frequently used tumor marker and serves as a prognostic indicator in patients with pancreatic cancer(PC). The platelet-to-lymphocyte ratio(PLR) is thought to be an inflammation-related serum marker. An elevated PLR represents increased inflammatory status and is associated with poor prognosis in patients with various cancers including PC. Methods: This study involved 103 patients with a histopathological diagnosis of pancreatic ductal adenocarcinoma who underwent pancreatectomy. The patients were assessed to determine the prognostic significance of the combination of the PLR and CA19-9 level. Results: Based on the receiver operating characteristic analysis results, the patients were divided into PLR H igh(PLR ≥ 129.1) andPLRLow(PLR < 129.1) groups and into CA19-9High(CA19-9 ≥ 74.0 U/mL) and CA19-9Low(CA19-9 < 74.0 U/mL) groups. The cumulative 5-year overall survival(OS) and disease-specific survival(DSS) rates significantly differed by both the PLR(PLR H igh group: 19.5% and 22.9%;PLRLow group: 39.1% and 45.9%) and CA19-9(CA19-9 H igh group: 19.1% and 25.6%;CA19-9Low group: 41.0% and 41.0%). We then divided the patients into Groups A(PLR L ow/CA19-9Low), B(PLR Low/CA19-9High or PLRHigh/CA19-9Low), and C(PLR H igh/CA19-9High). The cumulative 5-year OS rates in Groups A, B, and C were 44.0%, 31.9%, and 11.9%, respectively( P = 0.002). The cumulative 5-year DSS rates in Groups A, B, and C were 47.7%, 36.4%, and 16.8%, respectively( P = 0.002). Multivariate analysis revealed that the combination of the PLR and CA19-9 was an independent prognostic factor in patients with resected PC. Conclusions: The combination of the PLR and CA19-9 is useful for predicting the prognosis of patients with resected PC.

Monocyte-to-lymphocyte ratio as a prognostic factor in peripheral whole blood samples of colorectal cancer patients

BACKGROUND Colorectal cancer is the third most common malignancy worldwide.Therefore,it is critically important to identify new useful markers that can be easily obtained in routine practice.Inflammation is a crucial issue in the pathogenesis and development of cancer.AIM To evaluate the prognostic value of absolute monocyte count,monocyte to lymphocyte ratio(MLR),the combination of neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio(NLR-PLR),and combined platelet and neutrophilto-lymphocyte ratio(PLT-NLR)in peripheral blood samples of patients with colorectal cancer undergoing surgery.METHODS We conducted a retrospective study of 160 patients with colorectal cancer who underwent surgery,and 42 healthy controls.The status of absolute monocyte count,MLR,NLR-PLR and PLT-NLR was calculated on the basis of blood samples obtained before and after surgery.Haematologic factors were examined in correlation with the type of tumour growth,tumour size,histological type,percentage of mucinous component,grade of malignancy,Tumour-Node-Metastasis stage,venous,lymphatic and perineural invasion of cancer cells,status of lymph node invasion and the presence of cancer cell deposits.The Kaplan-Meier method and the long-rank test were used to compare survival curves.To determine independent prognostic factors,univariate and multivariate Cox proportional hazards regression models were applied.RESULTS The PLT-NLR status was correlated with tumour size and the presence of perineural invasion(P=0.015;P=-0.174,P=0.037).Moreover,high NLR-PLR and PLR-NLR ratios in the blood samples obtained after surgery were positively associated with histological type of cancer and percentage of the mucinous component(NLR-PLR:P=0.002;P=0.009;PLR-NLR status:P=0.002;P=0.007).The analysis of 5-year disease-free survival showed that the MLR of whole blood obtained after surgery[HR=2.903,95%CI:(1.368-6.158),P=0.005]and the status of lymph node metastasis[HR=0.813,95%CI:(0.653-1.013),P=0.050]were independent prognostic factors in colorectal cancer patients.CONCLUSION The postoperative MLR in whole blood samples can be used as an independent prognostic factor in patients diagnosed with colorectal cancer.

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.

The Prognostic Significance of the Preoperative Platelet-Lymphocyte Ratio in Japanese Patients with Localized Breast Cancer

Inflammation has been shown to be a factor in tumorigenesis. The circulating platelet to lymphocyte ratio (PLR) is a representative index of systemic inflammation. In this study, we analyzed the association between preoperative PLR levels and clinicopathological variables in two hundred sixty-four Japanese patients with localized breast carcinoma. We also evaluated the prognostic significance of preoperative PLR levels using the Cox proportional hazard model. Seventy-five patients (28.4%) had elevated PLR values, whereas 189 (71.6%) had depressed PLR values. The PLR correlated significantly with venous invasion (P < 0.05). Disease-free survival rates were significantly worse among patients with elevated PLR values than among those with lower PLR value (5-year survival, 81.6% vs. 90.7%, respectively;P < 0.05). In multivariate analysis, elevated PLR, nuclear grade, and lymph node involvement were significant prognostic factors for disease-free survival in patients with breast carcinoma (P < 0.05). Preoperative PLR levels may be an independent prognostic factor in patients with breast carcinoma.

Neutrophil-Lymphocyte Ratio as a Prognostic Factor in Incurable Stage IV Colorectal Cancer

Objectives: Our aim is investigating the predictive potential of these available and convenient laboratory dates in stage IV colorectal cancer (CRC) patients. Methods: We identified the cases of 114 consecutive patients who underwent the surgery at our Hospital between January 2006 and December 2012 by using the multivariate analysis, the Cox proportional-hazard regression model. Results: Multivariate analysis for the predictors of survival showed metastatic lesion resection [hazard ratio (HR) = 3.2, 95% confidence interval (CI) 1.6 - 6.6;p = 0.007] and only primary lesion resection (HR = 1.9, 95% CI 1.1 - 4.0;p = 0.045) remained independently significant prognostic factors. Therefore, we divided in 3 groups, 1) metastatic lesion resection group with primary lesion resection (n = 52 in the Met/Prim lesion group), 2) primary lesion resection without metastatic lesion resection (n = 38 in the Primary lesion group) and 3) palliative operation (n = 24 in the Palliative group). Age was the only independent risk factor in the Met/Prim lesion group. In the Primary lesion group, Neutrophil lymphocyte ratio (NLR) > 5, elevated Alanine aminotransferase and patients without chemotherapy were correlated with poor survival. In the Palliative group, NLR > 5 and patients who could not be treated with chemotherapy remained independent predictors of worse survival. Conclusions: NLR is not only simple and convenient for classification of patients, but also one of the important predictors of mortality for stage IV incurable CRC patients.

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.

Novel immunological and nutritional-based prognostic index for gastric cancer

AIM: To assess the prognostic significance of immunological and nutritional-based indices, including the prognostic nutritional index(PNI), neutrophillymphocyte ratio(NLR), and platelet-lymphocyte ratio in gastric cancer.METHODS: We retrospectively reviewed 632 gastric cancer patients who underwent gastrectomy between1998 and 2008. Areas under the receiver operating characteristic curve were calculated to compare the predictive ability of the indices, together with estimating the sensitivity, specificity and agreement rate.Univariate and multivariate analyses were performed to identify risk factors for overall survival(OS). Propensity score analysis was performed to adjust variables to control for selection bias.RESULTS: Each index could predict OS in gastric cancer patients in univariate analysis, but only PNI had independent prognostic significance in multivariate analysis before and after adjustment with propensity scoring(hazard ratio, 1.668; 95% confidence interval:1.368-2.035). In subgroup analysis, a low PNI predicted a significantly shorter OS in patients with stage Ⅱ-Ⅲ disease(P = 0.019, P < 0.001), T3-T4 tumors(P <0.001), or lymph node metastasis(P < 0.001). Canton score, a combination of PNI, NLR, and platelet, was a better indicator for OS than PNI, with the largest area under the curve for 12-, 36-, 60-mo OS and overall OS(P = 0.022, P = 0.030, P < 0.001, and P = 0.024,respectively). The maximum sensitivity, specificity, and agreement rate of Canton score for predicting prognosis were 84.6%, 34.9%, and 70.1%, respectively.CONCLUSION: PNI is an independent prognostic factor for OS in gastric cancer. Canton score can be a novel preoperative prognostic index in gastric cancer.

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.
