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.
Objective To assess the value of arsenious acid in treatment for metastatic liver cancer and inspect its adverse reaction through comparison between the therapeutic effect of arsenious acid-FOLFOX4 combined chemotherapy and that of single FOLFOX4 chemotherapy. Methods Twenty-six patients with metastatic liver cancer were selected from July 2006 to December 2007 in Huadong Hospital. All the cases were averagely divided into therapy group and control group randomly, arsenious acid combined FOLFOX4 chemotherapy was performed in therapy group and single FOLFOX4 chemotherapy in control group. Results The total of 26 cases completed at least 2 cycles of arsenious acid-FOLFOX4 combined chemotherapy or single FOLFOX4 chemotherapy. During 6-24 months follow-up (median 12.5 months), the average survival time of the therapy group was 242 d, the median survival time was 281 d, and the average survival time of the control group was 227 d, the median survival time was 246 d, there was no statistical difference between two groups (Pgt;0.05). Pain: There were 2 cases of complete remission (CR), 5 cases of partial remission (PR), 2 cases of stable disease (SD) in therapy group, the objective effect (CR+PR+SD) was 9 cases. There were 1 case of CR, 3 cases of PR, 2 cases of SD in control group, the objective effect (CR+PR+SD) was 6 cases. Objective efficacy: There were no CR cases in two groups. In therapy group, there were 5 cases of PR, 6 cases of NC, 2 cases of PD, the objective effect (CR+PR) was 5 cases, the benefit (CR+PR+NC) was 11 cases. In control group, there were 2 cases of PR, 4 cases of NC, 7 cases of PD, the objective effect (CR+PR) was 2 cases, the benefit (CR+PR+NC) was 6 cases. There was no significant difference of the objective effect between two groups (Pgt;0.05), but the benefit was significantly different (Plt;0.05). The major toxic reactions were digestive tract side effect, hepatic and hematological toxicity in two groups. Conclusions Arsenious acid-FOLFOX4 combined chemotherapy can lead to good therapeutic effect. Arsenious acid will not increase the adverse reaction of normal chemotherapy.
