SGLT-2 inhibitors reduce overall, lung, and thyroid cancer risk versus DPP-4i in T2DM.
Background
Type 2 Diabetes Mellitus (T2DM) patients face an elevated risk of developing various cancers. While sodium-glucose cotransporter-2 inhibitors (SGLT-2i) are widely used for their glycemic control and established cardiovascular and renal benefits, their long-term impact on cancer risk has remained a subject of controversy. Current evidence is conflicting, leaving a critical gap in understanding whether SGLT-2i offer protective effects or pose risks regarding oncogenesis. Clarifying this association is crucial for comprehensive patient care and informing cancer prevention strategies in the T2DM population.
Study Design
Researchers conducted an active-comparator, new-user cohort study using the Shenzhen Public Health Data Platform. They emulated a target trial comparing SGLT-2 inhibitors against two reference medications: Dipeptidyl peptidase-4 inhibitors (DPP-4i) and glucagon-like peptide-1 receptor agonists (GLP-1RA). The primary cohort, comparing SGLT-2i to DPP-4i, included 134,481 patients. Participants were followed for a median of 1.8 years, with cancer incidence as the primary endpoint. Overlapping weighting-based Cox proportional hazards models were used to assess hazard ratios (HRs) and 95% confidence intervals (CIs), adjusting for confounders.
