AbstractChemotherapy-induced nausea and vomiting (CINV) is associated with a significant deterioration in quality of life and is one of the reasons for the discontinuation of treatment. Olanzapine is known as an atypical antipsychotic agent, but it has been reported to be effective in treating refractory CINV due to its broad and potent inhibitory activity at multiple receptors involved in the nausea and vomiting pathways. This study was conducted to assess the efficacy of olanzapine for the prevention of CINV after moderately or highly emetogenic chemotherapy. After a search of Medline (Ovid), PubMed, CNKI, Wanfang and Weipu from 1990 to October 2013, all randomised controlled trials of olanzapine for the prevention of CINV were included in this study. The meta-analysis was performed using RevMan 5.0.19 software. 6 studies involving 726 total patients were included, of which 441 were Chinese oncology patients. We found that for both general populations and Chinese populations, antiemetic regimens including olanzapine are more effective at reducing CINV than regimens that do not include olanzapine, especially in the delayed phase of CINV.
