The relationship between diabetes and pancreatic cancer is complex. Diabetes or impaired glucose tolerance is present in more than 2/3rd of pancreatic cancer patients. Epidemiological studies have consistently shown a modest increase in the risk of pancreatic cancer in type 2 diabetes, with an inverse relationship to duration of disease. Additionally, recent studies suggest that anti-diabetic medications may modulate the risk of pancreatic cancer in type 2 diabetes. Subjects >50 years of age with new onset diabetes are at higher risk of having pancreatic cancer. However, to screen new-onset diabetes for pancreatic cancer, additional markers are needed that can distinguish pancreatic cancer-associated diabetes from type 2 diabetes.
糖尿病与胰腺癌之间的关系很复杂。超过三分之二的胰腺癌患者存在糖尿病或糖耐量受损。流行病学研究一直表明,2型糖尿病患者患胰腺癌的风险略有增加,且与病程呈负相关。此外,最近的研究表明,抗糖尿病药物可能会调节2型糖尿病患者患胰腺癌的风险。50岁以上新发糖尿病的患者患胰腺癌的风险更高。然而,要筛查新发糖尿病患者是否患有胰腺癌,还需要其他标志物来区分胰腺癌相关糖尿病和2型糖尿病。
