Association between sodium-glucose cotransporter 2 inhibitors and cancer: a systematic review and meta-analysis of randomized active-controlled trials
摘要
The effect of sodium-glucose cotransporter 2 (SGLT2) inhibitors on cancer incidence compared to other hypoglycemic drugs remains unclear.
AimThis systematic review and meta-analysis was designed to investigate the association of SGLT2 inhibitors with cancer compared to active comparators.
MethodA systematic search was conducted up to March 11, 2024 across Web of Science, PubMed, and ClinicalTrials.gov, and included trials with a follow-up period of at least 52 weeks. The Mantel–Haenszel statistical method was utilized, applying risk ratio (RR) and 95% confidence intervals (CI) for binary variables.
ResultsTwenty trials covering 16,399 type 2 diabetes mellitus patients were included. Median follow-up duration was 1.0 (1.0) years. The effect of SGLT2 inhibitors on the overall risk of cancer was neutral compared to active comparators (RR 1.00; 95%CI 0.71–1.40; p = 0.99; moderate certainty of evidence). SGLT2 inhibitors did not have a significant impact on breast cancer, endometrial/uterine cancer, gastrointestinal cancer, prostate cancer, renal cancer, or respiratory cancer. Subgroup analysis indicated a significant reduction in the risk of gastrointestinal cancer with SGLT2 inhibitors compared to metformin (RR 0.23; 95%CI 0.06–0.95; p = 0.04). SGLT2 inhibitors potentially increased gastrointestinal cancer risk relative to sulfonylureas (RR 3.52; 95%CI 0.91–13.64; p = 0.07).
ConclusionSGLT2 inhibitors showed neutral cancer risk in T2DM patients but may reduce gastrointestinal cancer versus metformin, guiding tailored therapy based on patient risk profiles.
