Objective  To systematically evaluate the correlation between coffee and risk of endometrial cancer.
Methods  Such databases as CBM, CNKI, WanFang data, PubMed, EMbase and The Cochrane Library (Issue 5, 2012) were searched to collect the prospective cohort studies about correlation between coffee and endometrial cancer. The retrieval time was by the end of May 2012, and the references of the included literature were also retrieved. Two evaluators independently screened the literature according to the inclusion and exclusion criteria, extracted the data, and assessed the quality, and then the statistical analysis was conducted by using Stata 12.0 software.
Results  A total of 10 cohort studies involving 4 484 patients with endometrial cancer were included. The results of meta-analysis showed that, compared with the women who didn’t drink coffee or drank in the lowest dose, the women who drank coffee in the highest dose had a decreased risk of endometrial cancer (RR=0.69, 95%CI 0.62 to 0.78), same as the women who drank coffee frequently (RR=0.83, 95%CI 0.77 to 0.89). The results of dose-response analysis revealed that, when there was an increase of 2 more cups of coffee per day, there was the risk of endometrial cancer decreased by 12%.
Conclusion  Drinking coffee frequently (more than 2 cups per day) can decrease the risk of endometrial cancer which can be significantly decreased when drinking in a big dose (more than 5 cups per day).
