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 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 current situation of anxiety and depression in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) and analyze the related influencing factors. Methods A questionnaire survey was conducted among AECOPD patients admitted to the Department of Respiratory and Critical Care Medicine, the Second Affiliated Hospital of Anhui Medical University from August 2022 to October 2023. The survey included basic demographic information, anxiety and depression scores, quality of life and dyspnea symptoms in the AECOPD patients. The clinical data of patients in the electronic medical record system were also collected. According to the anxiety score or depression score, the patients were divided into an anxiety group and a non-anxiety group, or a depression group and a non-depression group. The indicators between two groups were compared and the influencing factors were analyzed. Results Among the 164 patients with AECOPD, 123 patients (75.0%) were complicated with anxiety, 125 patients (76.2%) were complicated with depression, and 105 patients (64.0%) were complicated with anxiety and depression. Education level, place of residence, monthly income, smoking index, and chronic obstructive pulmonary disease assessment test (CAT) score were associated with AECOPD and anxiety (P<0.05). Higher CAT score was an independent risk factor for anxiety in the patients with AECOPD. Residence, monthly income, smoking index, CAT score, modified British Medical Research Council (mMRC) dyspnea questionnaire rating, actual bicarbonate, neutrophilic granulocyte percentage (NEU%), lymphocyte percentage (LYM%), basophile percentage (BASO%), alkaline phosphatase, total carbon dioxide concentration, neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) were associated with AECOPD and depression (P<0.05). Among them, higher CAT score and PLR value were independent risk factors of AECOPD and depression. Conclusion Anxiety and depression have higher prevalence in AECOPD patients, and the influencing factors include quality of life, dyspnea symptoms, education level, place of residence, monthly income, smoking index, acid base balance, NEU%, LYM%, BASO%, NLR和PLR, etc.
