根治性手術(shù)非小細(xì)胞肺癌患者手術(shù)前后NLR及其變化與預(yù)后的關(guān)系
[Abstract]:Background: The tumor has been one of the main factors for human health and the average life span of the population. According to the 2012 global cancer report, lung cancer is the first type of malignant cancer currently in the world, with non-small cell lung cancer (NSCLC) accounting for about 80% of all lung cancer, posing a serious threat to human health. With the development of medical knowledge and the continuous improvement of medical level, various treatment methods have effectively prolonged the survival of patients with lung cancer, but their prognosis is still not optimistic. It is found that the relevant index of the prognosis of the accurate and high-efficiency lung cancer patients can assist the clinician in the accurate screening of high-risk patients, and timely give the necessary auxiliary treatment, which can effectively improve the 5-year survival rate and the quality of life of the patients with NSCLC, and has great significance for clinical work. Objective: In recent years, more and more scientific research results show that the occurrence and progression of the tumor are closely related to the inflammatory factors of the body, in which the ratio of the neutrophil-lymphocyte ratio (NLR) is considered to be related to a variety of tumors, including lung cancer, hepatocellular carcinoma, colorectal malignant tumor, The prognosis of gastric malignant tumor is closely related. However, at present, most studies focus on the relationship between the NLR and the prognosis of the lung cancer before the operation of the patient, and less attention to whether the postoperative NLR and the change of the patient are related to the prognosis. The purpose of this study was to evaluate the relationship between the value of the NLR, the change of the NLR, the rate of change and the patient's survival time in the patients with NSCLC who underwent radical operation, and to discuss the value of the clinical application. Methods: 87 patients who underwent radical resection of non-small cell lung cancer in Qilu Hospital of Shandong University from December 2009 to August 2011 were retrospectively studied. All patients included in our study need to meet the pre-set enrollment criteria for the study. the incidence age, the sex, the bad habit of smoking, the mode of operation, the location of the tumor, the TNM stage, the type of the tumor and the degree of differentiation, the number of the positive lymph nodes of the tumor metastasis, The blood routine data completed in our hospital within one week prior to the operation of the patient and more than one month after the operation were collected, and the NLR was calculated according to the absolute number of the Neutrophil (NEU) and the absolute number of lymphocytes (LY). The patient was divided into a high NLR group and a low NLR group prior to the procedure with the NLR = 2.71. The patient was divided into a high NLR group and a low NLR group after operation with NLR = 3.62. The survival analysis was carried out by the Kaplan-Meier method, and the difference of the two groups was analyzed by log-rank test to compare the difference between the disease-free survival time (DFS) and the total survival time (OS) among the groups of the clinical factors, and the relationship between the factors and the patient's DFS and OS was analyzed by using the COX regression analysis. All the data were completed in the ss-24.0statistical software, and the difference between the groups was significant. Results: In general data, the habit of smoking is a factor that affects the prognosis of patients with radical operation NSCLC (P0.05). The number of operative, TNM staging and the number of positive lymph nodes in tumor metastasis was a clinical-related index that affected the prognosis of the patients (P0.05). The value of NLR (Sup2 = 4.663, P = 0.031), NLR (Sup2 = 2.801, P = 0.001), and NLR (Sup2 = 10.936, P = 0.001) were the factors influencing the prognosis of NSCLC patients. However, the above related factors were included in the results of the COX regression analysis: only the number of positive lymph nodes and the value of the NLR change in the tumor metastasis were the independent predictors of the prognosis. Conclusion: The results of this study show that not only the pre-operative NLR is the evaluation index of the prognosis of patients with NSCLC, and the change of NLR and NLR after operation can be used as the evaluation index of DFS and OS of the patients. and the prognosis of the patients with NSCLC after radical operation is superior to that of the NLR before operation. Because the acquisition of the NLR only needs the blood routine result, it is a simple, cheap and fast evaluation index for each patient before and after the operation, before and after the radiotherapy and chemotherapy or in the review. In future treatment, the clinician can divide the patients with NSCLC who have undergone radical surgery into high and low risk groups according to the NLR parameters and thereby provide the patient with the best treatment.
