Risk of Malignant Neoplasia with Glucagon-Like Peptide-1 Receptor Agonist Treatment in Patients with Type 2 Diabetes: A Meta-Analysis

الملخص EN

Background.

Glucagon-like peptide-1 (GLP-1) receptor agonists are effective glucose-lowering drugs, but there is concern that they may increase the risk of malignant neoplasia.

The present meta-analysis examined the safety of GLP-1 receptor agonists with regard to malignant neoplasia.

Methods.

We analyzed data from randomized controlled trials with a minimum duration of 24 weeks that assessed the incidence of neoplasms in type 2 diabetes patients receiving GLP-1 receptor agonists compared with placebo or other hypoglycemic drugs.

We searched the MEDLINE, Embase, and Cochrane databases with a language restriction of English through October 1, 2018, and carried out a meta-analysis of the available trial data using a fixed effects model to calculate odds ratios (ORs) for neoplasia.

Results.

Thirty-four relevant articles, providing data for 50452 patients, were included in the meta-analysis.

Compared with the incidence of malignant neoplasia with placebo or other interventions, no increase in malignant neoplasm formation was observed with the use of GLP-1 receptor agonists (OR 1.04, 95% confidence interval (CI) 0.94–1.15; p=0.46), liraglutide (OR 1.08, 95% CI 0.91–1.27; p=0.38), exenatide (OR 1.00, 95% CI 0.86–1.16; p=1.00), semaglutide (OR 0.89, 95% CI 0.35–2.22; p=0.80), or albiglutide (OR 1.07, 95% CI 0.23–4.88; p=0.93).

A subanalysis of trials lasting longer than 3 years also showed no increase in the neoplasia risk with GLP-1 receptor agonist use (OR 1.03, 95% CI 0.92–1.15; p=0.60).

Between-trial statistical heterogeneity was low for all comparisons.

Conclusion.

GLP-1 receptor agonists can be used without safety concerns related to malignant neoplasia in patients with type 2 diabetes.
