Abstract:
Objective To investigate the association between diabetes mellitus and risks of kidney cancer.Methods The cohort and case-control studies on the association between diabetes mellitus and risk of kidney cancer were analyzed by searching PubMed database within the time limit of Jan.1990 to Oct.2011.Data were selected according to the inclusion and exclusion criteria,and the meta-analysis was performed by using the Cochrane Collaboration's RevMan 5.0 software.Results A total of 14 studies(8 cohort studies and 6 case-control studies) involving 6,645,516 participants met the inclusion criteria.Meta analysis showed that patients with diabetes had a higher risk of kidney cancer compared with the control group without diabetes(OR =1.28,95％ CI 1.10 ～ 1.48,P ＜ 0.05).Stratification study showed that diabetes was associated with an increased risk of kidney cancer in cohort studies(OR =1.32,95％ CI 1.14-1.53,P ＜0.05),but this association was not found in casecontrol studies (OR =1.21,95 ％ CI 0.79-1.84,P ＞ 0.05).Conclusion This meta-analysis indicates a positive association between diabetes and risk of kidney cancer,however,future researches are needed to identify whether diabetes mellitus is an independent risk factor for kidney cancer.
