Objective To determine whether neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) are important prognostic factors in patients with colorectal cancer, and to clarify relationship between NLR or PLR and TNM staging in colorectal cancer. Methods The clinical data of 304 patients with colorectal cancer who were admitted to the same medical group from January 2013 to December 2013 in the West China Hospital of Sichuan University were analyzed retrospectively. The relationship between NLR or PLR and the clinicopathologic characteristics and its effects on prognosis of patients with colorectal cancer were analyzed. Results The critical values of NLR (sensitivity=51.0%, specificity=75.4%, area under the receiver operating characteristic curve=0.66) and PLR (sensitivity=73.0%, specificity=46.4%, area under the receiver operating characteristic curve=0.60) was 2.27 and 155.92, respectively, with a 3-year cumulative survival rate as the end point. According to the critical values of NLR and PLR, there were 133 cases in a low NLR group (NLR≤2.27), 171 cases in a high NLR group (NLR>2.27), 207 cases in a low PLR group (PLR≤155.92), 97 cases in a high PLR group (PLR>155.92). ① The 3-year survival rate was 91.5% and 77.2% in the low NLR group and the high NLR group, respectively, which was 89.0% and 72.8% in the low PLR group and the high PLR group, respectively. The survival curves of NLR and PLR on prognosis prediction had significant differences (P=0.002, P=0.001). ② The results of multivariate analysis showed that the NLR was the independent risk factor for colorectal cancer (P=0.004), whereas PLR was not the independent risk factor for colorectal cancer (P=0.408). ③ The NLR and PLR were associated with the tumor TNM staging (P=0.002, P=0.000), which in the colorectal cancer with stage Ⅳ was significantly higher than those with stage Ⅰ–Ⅲ (P<0.05). ④ The NLR and PLR were associated with T stage (P=0.006, P=0.031). The NLR in the colorectal cancer with stage T4 was significantly higher than that with stage Ⅰ (P=0.015) or stage Ⅱ (P=0.032). The PLR in the colorectal cancer with stage T4 was significantly higher than that with stage Ⅱ (P=0.013). ⑤ The NLR was not associated with N staging (P=0.118). The PLR was associated with N staging (P=0.007), which in the colorectal cancer with N2 stage was significantly higher than that with N0 stage (P=0.008) or N1 stage (P=0.019). ⑥ The NLR and PLR in the colorectal cancer with stage M1/M2 were significantly higher than those with stage M0 (P=0.004, P=0.001). Conclusions Preliminary results of this study show that NLR is an important independent prognostic indicator for patient with colorectal cancer. While PLR is significantly increased when lymph node metastasis occurs, and platelet elevation might be related to lymph node metastasis.
ObjectiveTo study the clinical significance of prognostic nutritional index (PNI) combined with neutrophil to lymphocyte ratio (NLR) in predicting the occurrence of anastomotic leakage after radical gastrectomy for gastric cancer.MethodsTo retrospectively analyze and collect the clinical data of 517 patients with gastric cancer who were diagnosed at the Third People’s Hospital of Shangqiu City from January 2016 to May 2020, all of the patients received radical gastrectomy. We explored the risk factors that affect the occurrence of postoperative anastomotic leakage, and explored the clinical significance of PNI combined with NLR on the third day after operation in predicting the occurrence of anastomotic leakage.ResultsAmong 517 patients undergoing radical gastrectomy, 61 had anastomotic leakage, and the incidence of anastomotic leakage was 11.8%. The results of multivariate logistic regression analysis showed that patients with preoperative diabetes and intraoperative blood loss ≥400 mL had a higher incidence of anastomotic leakage, and with the increase of NLR value on the 3rd and 5th day after operation, and the decrease of PNI value on the 3rd and 5th day after operation, the incidence of anastomotic leakage increased (P<0.05). The area under the curve of NLR, PNI, and NLR combined with PNI on the 3rd day after operation in predicting the occurrence of anastomotic leakage were 0.849, 0.581, and 0.949, respectively, and the differences were statistically significant (P<0.05), the sensitivity and specificity of NLR combined with PNI were higher than the individual indicator.ConclusionPNI combined with NLR on the 3rd day after operation has important clinical significance in predicting the occurrence of anastomotic leakage after radical gastrectomy for gastric cancer.
ObjectiveTo explore the combined application of neutrophil to lymphocyte ratio (NLR) and systemic immune inflammation index (SII) on the prognosis of hepatitis B-related hepatocellular carcinoma after resection.MethodsRetrospectively collected data of 180 patients with hepatitis B-related hepatocellular carcinoma who were hospitalized in the Department of Infectious Diseases and Hepatobiliary Surgery of the Affiliated Hospital of Southwest Medical University and received surgical treatment from January 2013 to December 2019, including general information, laboratory examination and abdominal CT or MRI results. NLR and SII values were measured at one week before operation, and their critical values of NLR and SII were determined by ROC curve analysis. Univariate and multivariate analysis were performed to determine the risk factors to predict the survival status of patients with hepatitis B-related hepatocellular carcinoma after hepatectomy.ResultsUnivariate analysis showed that AFP, platelets, TNM staging, portal vein tumor thrombus, tumor differentiation, NLR, SII, and NLR+SII combined score were significantly correlated with the prognosis of patients with hepatitis B-related hepatocellular carcinoma (P<0.05). Multivariate analysis showed that PLT [HR=1.791, 95%CI (1.124, 2.854), P=0.014], NLR [HR=4.289, 95%CI (2.571, 7.156), P<0.001], SII [HR=5.317, 95%CI (3.016, 9.374), P<0.001], and NLR+SII combined score [HR=7.901, 95%CI (4.124, 15.138), P<0.001] were independently correlated with the survival of patients with hepatitis B-related hepatocellular carcinoma.ConclusionsThe preoperative NLR+SII combined score can be used to evaluate the postoperative prognosis of patients with hepatitis B-related hepatocellular carcinoma. The higher the score, the lower the postoperative survival rate.
ObjectiveTo investigate the application progress of peripheral blood neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) in various treatment methods of hepatocellular carcinoma(HCC), aiming to fully understand the value of NLR and PLR in various treatments of HCC.MethodRetrieved and reviewed domestic and foreign literatures related to peripheral blood NLR and PLR and HCC in recent years.ResultsThe treatment of HCC mainly included liver resection, liver transplantation, transarterial chemoembolization, radiofrequency ablation, and sorafenib. Peripheral blood NLR and PLR were related to the survival of HCC patients after treatment. High NLR and PLR often indicated poor prognosis for HCC patients.ConclusionNLR and PLR play a certain role in various treatment methods of HCC, and have a certain value in judging tumor prognosis, recurrence, and metastasis.
Objective To investigate the correlation between the neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), systemic immune inflammation index (SII) and clinicopathological characteristics and prognosis in patients with gastrointestinal stromal tumor (GIST). Methods The clinicopathological data and blood routine results of 101 patients with GIST who were treated surgically in the General Hospital Western Theater Command PLA from December 2014 to December 2018 were collected retrospectively, samples were obtained to calculate NLR, PLR and SII. The optimal cutoff value of NLR, PLR and SII were evaluated by receiver operating characteristic (ROC) curve. The Chi-square test and t-test were used to analyze the relationship between NLR, PLR, SII and clinicopathological characteristics of GIST. The Kaplan-Meier plots and the log-rank test were used to analyze the influence factors affecting the recurrence-free survival (RFS) of patients with GIST. Multivariate Cox regression analyses was used to identify the independent influence factors affecting the RFS of patients with GIST. Results The preoperative peripheral blood NLR, PLR and SII of patients with GIST were correlated with the tumor site, tumor diameter and modified NIH risk stratification (P<0.05), but not with the mitotic count of tumor cells (P>0.05). Kaplan-Meier plots and log-rank test showed that NLR, PLR, SII, surgical method, tumor site, tumor diameter, mitosis rate and modified NIH risk stratification were the influential factors of RFS in with GIST. The multivariate Cox regression analysis revealed that postoperative whether to accept regular imatinib adjuvant therapy (HR=32.876, P<0.001), modified NIH risk stratification (HR=129.182, P<0.001), and PLR (HR=5.719, P=0.028) were independent influence factors affecting the RFS of patients with GIST. Conclusions Preoperative peripheral blood PLR, NLR, and SII are correlated with clinicopathological characteristics such as the tumor location, tumor diameter and modified NIH risk stratification, and are the influencing factors of postoperative RFS in patients with GIST. PLR is an independent predictor of RFS in patients with GIST.
Acute cerebral infarction is characterized by high incidence rate, high recurrence rate, high disability rate and multiple complications. Early evaluation and treatment of acute cerebral infarction is particularly important to improve the survival rate and prognosis of patients. As an easily available clinical laboratory indicator, blood routine test can reflect the pathological changes in the body to a certain extent. In recent years, many studies have shown that the indicators such as red cell volume distribution width, mean platelet volume, neutrophil to lymphocyte ratio and platelet to lymphocyte ratio in blood routine examination have important values in the onset, severity and prognosis of acute cerebral infarction. This article reviews the correlations of the above parameters and ratio parameters with acute cerebral infarction, in order to provide some reference and basis for clinical diagnosis, treatment and prognosis evaluation of acute cerebral infarction.
Objective To investigate the correlation of red blood cell distribution width (RDW) and neutrophil to lymphocyte ratio (NLR) with total imaging load of cerebral small vessel disease (CSVD), and the clinical diagnostic value of RDW, NLR and their combined indicators for high load of CSVD imaging. Methods The medical records of CSVD patients hospitalized in the Department of Neurology of Baotou Central Hospital between October 2018 and October 2022 were retrospective collected. The total imaging load of CSVD was obtained by evaluating the cranial MRI and divided into a low load group and a high load group. The general clinical data, past medical history, and blood biochemical indicators were compared between the two groups. The correlation analysis method was used to analyze the relationship between the relevant indicators and the total imaging load. Logistic regression analysis was used to analyze the risk factors of the total imaging load of CSVD. The receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of the detection indicators for clinical diagnosis. Results A total of 320 patients were included. Among them, there were 201 cases (62.81%) in the low load imaging group and 119 cases (37.19%) in the high load imaging group. Excepted for age, gender, history of hypertension, RDW, and NLR (P<0.05), there was no statistically significant difference in the comparison of other indicators between the two groups (P>0.05). Spearman correlation analysis showed that RDW (r=0.445, P<0.001) and NLR (r=0.309, P<0.001) were positively correlated with the total imaging load of CSVD. The results of multivariate logistic regression analysis showed that age, male gender, RDW, and NLR were risk factors for high imaging load of CSVD. The areas under the ROC curve of RDW, NLR, and their combined indicators were 0.733, 0.644, and 0.792, respectively.Conclusions In patients with CSVD, the levels of RDW and NLR are related to the total imaging load of CSVD, which are independent risk factors for high imaging load of CSVD. The levels of RDW and NLR have clinical diagnostic value in predicting CSVD high load.
