Murphy1,4  \nDiabetes medications may modify the risk of certain cancers. We systematically searched MEDLINE, Embase, Web of Science, and Cochrane CENTRAL from 2011 to March 2021 for studies evaluating associations between diabetes medications and the risk of breast, lung, colorectal, prostate, liver, and pancreatic cancers. A total of 92 studies (3 randomized controlled trials, 64 cohort studies, and 25 case–control studies) were identified in the systematic review, involving 171 million participants. Inverse relationships with colorectal (n = 18; RR = 0.85; 95% CI = 0.78–0.92) and liver cancers (n = 10;  \nRR = 0.55; 95% CI = 0.46–0.66) were observed in biguanide users. Thiazolidinediones were associated with lower risks of breast (n = 6; RR = 0.87; 95% CI = 0.80–0.95), lung (n = 6; RR = 0.77; 95% CI = 0.61– 0.96) and liver (n = 8; RR = 0.83; 95% CI = 0.72–0.95) cancers. Insulins were negatively associated with breast (n = 15; RR = 0.90; 95% CI = 0.82–0.98) and prostate cancer risks (n = 7; RR = 0.74; 95% CI = 0.56– 0.98). Positive associations were found between insulin secretagogues and pancreatic cancer (n = 5; RR = 1.26; 95% CI = 1.01–1.57), and between insulins and liver (n = 7; RR = 1.74; 95% CI = 1.08–2.80) and pancreatic cancers (n = 8; RR = 2.41; 95% CI = 1.08–5.36). Overall, biguanide and thiazolidinedione use carried no risk, or potentially lower risk of some cancers, while insulin secretagogue and insulin use were associated with increased pancreatic cancer risk.  \nAbbreviations  \nAGIs  \nCochrane CENTRAL EMBASE  \nHR MEDLINE NOS  \nOR PRISMA  \nPROSPERO  \nRCT RR 95% CI  \nAlpha-glucosidase inhibitors  \nCochrane Central Register of Controlled Trials  \nExcerpta Medica DataBase  \nHazard ratio  \nMedical Literature Analysis and Retrieval System Online Newcastle–Ottawa scale  \nOdds ratio  \nPreferred Reporting Items for Systematic Reviews and Meta-Analyses Prospective Register of Systematic Reviews  \nRandomized controlled trial  \nRelative risk  \n95% Confidence interval  \nThe prevalence of type II diabetes, herein referred to as diabetes, continues to grow and, globally, will affect 7.7%(439 million) of adults aged 20 to 79 years old by 20301. Epidemiological evidence suggests that diabetes is associated with a higher risk for many cancers, from 20 to 30% elevated breast or colorectal cancer to 97% elevated risk of intrahepatic cholangiocarcinoma or endometrial cancer2,3. These associations likely reflect shared etiology. For instance, tobacco use, physical inactivity, overweight, and poor diet are closely linked to cancer risk and progression4 and risk of diabetes5–7.
