BackgroundThe prognostic values of preoperative neutrophil/lymphocyte ratio (NLR), monocyte/lymphocyte ratio (MLR), and platelet/lymphocyte ratio (PLR) in non‐small cell lung cancer (NSCLC) have been previously described. This study assessed the prognostic values of other pretreatment complete blood cell parameters in Chinese patients with curatively resected NSCLC.MethodsA total of 1466 consecutive NSCLC patients who received curative surgery from January 1, 2005 to December 31, 2009 with complete data from pretreatment blood tests were enrolled in this retrospective study. Correlations between each blood test parameter and overall survival were examined by Kaplan–Meier method or Cox proportional hazards regression, followed by a stratification analysis of significant variables.ResultsOptimal cut‐off values of 0.55 for neutrophil/white blood cell ratio (NWR), 0.28 for lymphocyte/white blood cell ratio (LWR), 0.09 for monocyte/white blood cell ratio (MWR), 2.06 for NLR, 0.35 for MLR, 204.00 for PLR, and 38.25 for platelet/white blood cell ratio (PWR) were identified using X‐tile software. Univariate analysis suggested that NWR ≥ 0.55, LWR < 0.28, MWR ≥ 0.09, NLR ≥ 2.06, MLR ≥ 0.35, and PLR ≥ 204.00 predicted a poor prognosis in NSCLC patients. However, only NWR and MLR were identified as independent significant prognostic factors in multivariable analysis, especially in tumor node metastasis stage I and I/II/III NSCLCs.ConclusionPretreatment NWR, MWR, LWR, NLR, MLR, and PLR values are associated with poor overall survival for patients with curatively resected NSCLC. NWR and MLR are independent prognostic factors in curatively resected NSCLC.
BackgroundApatinib, a small‐molecule inhibitor of vascular endothelial growth factor receptor 2 (VEGFR‐2), has proven to be effective and safe for treating patients with advanced gastric cancer after second‐line chemotherapy failure. As VEGFR‐2 targeted therapy has made encouraging progress for the treatment of a broad range of malignancies, we explored the efficacy and safety of apatinib for the treatment of advanced non‐small cell lung cancer after the failure of chemotherapy or other targeted therapy.MethodsWe retrospectively analyzed the data of 34 patients (11 with squamous carcinoma and 23 with adenocarcinoma) who were treated with apatinib alone in a daily oral dose of 250 mg in the second‐line or third‐line setting from January 2016 to July 2017. The primary endpoint was progression‐free survival (PFS).Results EGFR mutation or amplification was detected in 15 patients. The median PFS of the whole group was four months (95% confidence interval 0.3–7.7). A partial response was observed in 2 patients (5.88%) and stable disease in 19 (55.88%). The disease control rate was 61.76%. Common side effects of apatinib were hypertension (n = 12), hand‐foot syndrome (n = 8), and proteinuria (n = 5), which accounted for 35.30%, 23.53%, and 14.71%, respectively, and no grade 3/4 adverse reactions occurred. Apatinib toxicity was controllable and tolerable.ConclusionsApatinib appears to be effective and safe for advanced non‐small cell lung cancer after the failure of chemotherapy or other targeted therapy.
e20626 Background: Apatinib, a small-molecule inhibitor of vascular endothelial growth factor receptor-2 (VEGFR-2), has been proved to be effective and safe in treating patients with advanced gastric cancer who failed to second-line chemotherapy. As the VEGFR-2 targeted therapy has made encouraging progress in the treatment of a broad range of malignancies, we aimed to explore the efficacy and safety of apatinib in treatment of advanced non-small cell lung cancer after the failure of chemotherapy or other targeted therapy. Methods: In this open-label single-arm, phase II study, patients were treated with apatinib alone in daily dose of 250 mg, po, in the second- or third-line setting. The primary endpoint was progression-free-survival (PFS) and the tumor response was determined according to the Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1. Results: From January 28, 2016 to December 31, 2016, 33 patients were enrolled, including 9 patients with squamous carcinoma and 24 patients with adenocarcinoma. Fourteen patients were detected as EGFR mutations and all the cases have no anaplastic lymphoma kinase (ALK) fusion gene. The median progression free survival (mPFS) of the whole group was 4.0 (95% confidence interval [CI], 0-8.2) months, while the mPFS of adenocarcinoma was 4.0 (95% CI, 2.1-5.9) months and the mPFS of squamous carcinoma was 5.5 (95% CI, 0-13.9) months (P = 0.245). Among the 33 patients, partial response was noted in 3 patients (9.09 %) and stable disease in 14 (42.42%). The disease control rate (DCR) was 51.52%. The common side effects of apatinib were hypertension, hand-foot syndrome and proteinuria, which accounted for 33.33%, 24.24%, and 15.15%, and no grade 3/4 adverse reactions occurred. The toxicity of apatinib was controllable and tolerable. Conclusions: Apatinib appears to be effective and safe for advanced non-small cell lung cancer after the failure of chemotherapy or other targeted therapy. Prospective studies are needed for further investigation.
