晚期非鱗非小細胞肺癌應用貝伐單抗療效的預測因素分析
[Abstract]:Background Non-small cell lung cancer (NSCLC) is one of the most common malignancies and the most common cause of cancer-related deaths worldwide. Most patients with NSCLC are diagnosed at advanced stage (stage III B or IV) and have poor prognosis. In recent years, epidermal growth factor receptor tyrosine kinase receptor inhibitor (EGFR-TKI), anaplastic lymphoma kinase The use of tyrosine kinase receptor inhibitors (ALK) opens a new chapter in the treatment of advanced NSCLC. However, only a few patients with NSCLC have EGFR or ALK-driven genes. For patients with negative driving genes, chemotherapy with platinum is still the standard treatment. Bevacizumab is a monoclonal antibody against vascular endothelial growth factor, which has been proved by many studies. Bevacizumab can further improve the efficacy of platinum-based chemotherapy in advanced NSCLC, but its objective Resonse Rate (ORR) is only 35% - 54%, which means that not all patients can benefit from bevacizumab treatment. Many researchers have explored predictors of the efficacy of bevacizumab. Objective To investigate the predictors of bevacizumab efficacy in advanced non-phosphorus NSCLC. Objective: To explore the predictors of the efficacy of bevacizumab in advanced NSCLC by analyzing the basic characteristics, pathological features, tumor markers, neutrophil lymphocyte ratio and blood biochemical parameters of patients, and to screen the most beneficiary population of bevacizumab so as to guide the clinical application of bevacizumab in advanced NSCLC. Methods The clinical data of 112 advanced NSCLC patients treated with bevacizumab in Shandong Cancer Hospital from June 2011 to January 2017 were analyzed retrospectively. The basic features, pathological features, tumor markers, neutrophil lymphocyte ratio and blood biochemistry were analyzed. Kaplan-Meier test, log-rank test, univariate Cox regression analysis were used for univariate analysis, and P0.1 was included in multivariate analysis; multivariate Cox regression was used to further analyze the effect of related factors on progression-free survival (PFS) after bevacizumab treatment, with statistical significance at p0.05. The median follow-up time was 2-36 months on January 20, 2017, with a median follow-up time of 11 months. The median PFS of all patients treated with bevacizumab was 11 months. 3, P = 0.028, double lung metastases (ORR 37.1%, 967 2 = 9.455, P = 0.002), pre-application metastasites (< 2 (ORR 41.2%, 962 = 5.216, P = 0.022), neutrophil lymphocyte ratio (NLR) (< 2.29 (ORR 37.0%, 962 = 5.099, P = 0.024), platelet lymphocyte ratio (96let, PLlet, lymphocyte ratio 962 = 5.216, P = 5.216, P = 0.022, P = 0.022), neutrophil lymphocyte lymphocyte ratio (NLR), NLR < 2.29 (ORR 37.0%, 967 2 = 1 Patients with mean platelet volume (MPV) less than 9.9 fL (ORR 36.7%, 2 = 5.873, P = 0.015) and lactate dehydrogenase (LDH) less than 179.5 U/L (ORR 43.8%, 2 = 18.223, P = 0.000) had a high response rate and a statistically significant difference in the long-term efficacy of bevacizumab. 9672 = 3.557, P = 0.057, P = 0.059, lobe (962 = 34.987, P = 0.000), lobe (962 = 34.987, P = 0.000), anatomtyping (962 = 12.853, P = 0.000), concurrentchemotherapy regimen (962 = 14.602, P = 0.000), time of application of bevacizum (962 = 14.577, P = 0.001), T stage (962 = 4.382 = 4.389, P = 0.N6, N stage (962 = 4.Nstage = 4.Nstage (962 = 4.Nstage), N stage (962 = 3.Nstage (962 = 3.962 = 3.Nstage 149, P = 0.0076, number of metastatic sites (_2 = 3.141, P = 0.076) Liver metastasis, liver metastasis (962 = 7.758, P = 0.005), bone metasta (962 = 4.34, P = 0.037), hemoglobin (HGB) (962 = 3.288, P = 0.070), LDH (962 = 4.266, P = 0.039), albumin (Albumin, ALB) levels (962 = 7.324, P = 0.004, P = 0.007), D2aggregate (962 = 7.2 = 7.403, P = 2 = 7.3, P = 3, P = P = 0.003, P = 0.007) and the use of albumin (albumin, albumin, albumin, albumin, albumin, There is a correlation between the efficacy of Vamvastatin. We have multiple reasons for this. The results showed that age (HR = 4.133, P = 0.007), lobe (HR = 37.206, P = 0.000), primary tumor T stage (HR = 0.114, P = 0.000), bone metastasis (HR = 2.685, P = 0.044), LDH level (HR = 0.245, P = 0.012), ALB level (HR = 7.670, P = 0.001) were independent prognostic factors. In this population, 60 years of age, lower lobe tumors, T1-T2 tumors before bevacizumab administration, no bone metastasis, ALB42.1g/L before bevacizumab, LDH < 179.5U/L were independent prognostic factors for bevacizumab administration.
