Abstract:
Objective:To evaluate the effects and safety of adjuvant chemotherapy for adults with malignant glioma. Method:PubMed,EMBASE,Cochrane Library,CNKI,Chinese Biomedical Database and VIP were reviewed and randomized controlled trials of adjuvant chemotherapy for adults with malignant glioma were identified.The quality of the included trials was evaluated by two reviewers.A meta-analysis was conducted in homogeneous studies.Result:13 controlled trials were involved in 3639 patients.The meta-analysis results showed that compared with radiotherapy alone,the adjuvant chemotherapy might increase 1 year survival,2 years survival,2 years progression free survival,and their OR and 95%CI were 0.61(0.43,0.87),0.52(0.33,0.81),and 0.42(0.19,0.90),respectively,but 1 year progression free survival and 5 years survival had no statistical significance.Their OR and 95%CI were 0.52(0.26,1.04) and 0.75(0.54, 1.04) respectively.5 studies(2418 cases) reported that the toxicity rates increased in patients who received radiotherapy plus adjuvant chemotherapy compared with those in patients who received radiotherapy alone.Conclusion:The adjuvant chemotherapy may increase one year survival and two years survival,and have advandage impact on 2 years and 5 years progression free survival.Owing to the high possibility of attrition bias and measurement bias in the included studies,there must be a negative impact on evidence intensity of our results and therefore,some randomized controlled trials with high quality have to be expected to obtain the best evidence.
