Using 2014–2024 electronic health record data from the OneFlorida+ multicenter health research network, Hao Dai, from the Indiana University School of Medicine, and colleagues compared the incidence of 14 cancers among more than 43,317 obese adults taking prescribed glucagon-like peptide-1 receptor agonists (GLP-1RAs) and 43,315 nonusers. The majority of patients were female (68.2%), and the mean age was 52.4 years.
The cancers observed in this retrospective study included 13 associated with obesity (liver, thyroid, pancreatic, bladder, colorectal, kidney, breast, endometrial, meningioma, upper gastrointestinal, ovarian, multiple myeloma, and prostate) and lung cancer.
The researchers found an overall 17% lower cancer risk among individuals taking GLP-1RAs compared with non-users, with the lowest risk for endometrial cancer, ovarian cancer, and meningioma. GLP-1RA use, however, was associated with an increased risk of kidney cancer, highlighting a need for longer-term follow-up.
