This study will examine whether the type of diabetes treatment used before cancer diagnosis is associated with survival and serious complications after obesity-associated cancer in adults with obesity and type 2 diabetes. The study focuses on glucagon-like peptide-1 receptor agonists (GLP-1 RA) and compares them with other commonly used glucose-lowering therapies, including SGLT2 inhibitors, DPP-4 inhibitors, sulfonylureas, metformin, and usual care. Using de-identified electronic health record data from the TriNetX US Collaborative Network, the study will assess whether patients who used GLP-1 RA before cancer diagnosis have different risks of death, hospitalization, sepsis, and other major outcomes after cancer diagnosis. This is an observational study designed to evaluate associations in routine clinical care and not to prove a treatment effect.
