Abstract:
Objective To explore the relationship between level of glucose metabolism and risk of cancer incidents.Methods 10 079 aged ≥40,local residents in Jiashan were enrolled by stratified cluster sampling method in 2011.All the subjects accepted retrospective investigation on incidents of diabetes mellitus and cancers plus blood testing for level of glucose metabolism.Differences between glucose metabolism level and cancer incidence were analyzed by trend Chi-square test.Results The prevalence of cancers in female diabetes mellitus patients was 268.79 per 100 000,higher than in males-124.31 per 100 000 (x2=4.012 2,P＜0.05).The incidence rates of cancers in groups of normal glucose regulation (NGR),impaired glucose regulation (IGR),and diabetes mellitus (DM) patients were 77.32 per 100 000,115.40 per 100 000 and 204.08 per 100 000,respectively.The incidence of cancers in local residents who were older than 40 years had increased with the decrease of glucose regulation ability.The subjects were divided into three groups by FPG,2h-PG and HbA1c levels respectively and the incident risks on cancers under each index increased 30.0％,39.0％ and 62.4％,respectively.Compared to the general population,the cancer incidence in DM group increased 1.67 times and 2.62 times increase in women but did not show significant difference in men (x2=0.524 0,P＞0.05).Breast and colorectal cancers were the most common tumors that accompanied with DM,and their incidence increased along with the decrease of glucose regulation ability.The incidence rates of breast and colorectal cancer in T2DM were 2.36 and 1.87 times more than in general population,and the incidence rates of female patients had an increase of 2.53 and 6.74 times,respectively.Conclusion The cancer incidence was higher in DM group than in the non-DM group while the incidence rates of both breast and colorectal cancer were relevant to the levels of glucose metabolism.
