  • Effectiveness of Endostar Combined with Chemotherapy for Advanced Non-Small Cell Lung Cancer: A Systematic Review

    Objective To evaluate the effectiveness and safety of Endostar combined with chemotherapy for non-small cell lung cancer (NSCLC). Methods Randomized controlled trials (RCTs) on Endostar combined with chemotherapy for NSCLC were searched in The Cochrane Library, MEDLINE, EMbase, VIP, CNKI, CBMdisc and other electronic databases. The quality of RCTs meeting inclusion criteria was evaluated and the data were extracted; meta-analyses were performed with RevMan 5.1 software, and then the GRADE System was used to rate the level of evidence and strength of recommendation. Results Among the 18 RCTs involving 1 825 cases included, 1 816 cases met the inclusion criteria. Meta-analyses showed that: compared with the single chemotherapy, Endostar combined with chemotherapy could increase the total effective rate (RR=1.85, 95%CI 1.56 to 2.11, Plt;0.000 01), and the clinical benefit response (RR=1.21, 95%CI 1.14 to 1.29, Plt;0.000 01), but decrease the incidence risk of leukopenia (RR=0.89, 95%CI 0.82 to 0.97, P=0.006). There were no signficant differences between the two groups in decreasing thrombocytopenia (RR=0.87, 95%CI 0.74 to 1.03, P=0.10), impaired renal function (RR=0.96, 95%CI 0.69 to 1.34, P=0.82), nausea and vomiting (RR=0.92, 95%CI 0.84 to 1.01, P=0.08) and other side effects. Based on GRADE, the level of evidence was Grade C, and the strength of recommendation was 2. Conclusion The present results of clinical trials show that Endostar combined with chemotherapy for NSCLC is a safe and effective therapy without increasing the toxic reaction and side effects; and based on GRADE, the level of evidence was Grade 2C, and the strength of recommendation was 2. However, in view of the limitations of this study, it is suggested that large-scale, high-quality researches on basic and clinical fields should be performed to further verify the above conclusion by critical outcome indicators.

  • How to Understand and Use GRADE System Correctly? A Briefly Outline

    Evidence is the core of Evidence-Based Medcine; the Grades of Recommendations Assessment, Development and Evaluation (GRADE System) is a milestone in the history of evidence development. This paper outlines the GRADE System and GRADEpro 3.2 software, and briefly explores the right and wrong application which was published in the Chinese Journal of Evidence-Based Medicine. The GRADEpro 3.2 software is easy to operate, but for evaluating the reasons of upgrade and downgrade, and the importance of the parameters of outcomes, it needs to comprehensively and systematically understand the knowledge of relevant background, and to construct a solid foundation in clinical epidemiology and systematic review. In view of this paper based on the current GRADE System, there may be some discrepancy to the later content with the GRADE System constant improvement. Therefore, it is bly recommended that readers should keep constant learning and improving.
