Use of GLP-1 receptor agonists is not associated with an increased risk of gastrointestinal cancers and may be associated with reduced risks of colorectal and liver cancers.
Current evidence from large randomized trials indicates that GLP-1 receptor agonists do not increase the risk of gastrointestinal cancers. In fact, they may be associated with a reduced risk of colorectal and liver cancers, particularly in older and obese patients. While these findings are reassuring, cancer was often a secondary endpoint, so long-term monitoring remains important.
GLP-1 RA use was not associated with an increased overall risk of GI cancers (HR 0.81: 95% CI: 0.68–0.96). Subgroup analyses indicated reduced risks of colorectal cancer (HR 0.81: 95% CI: 0.68–0.96) and liver cancer (HR: 0.74; 95% CI: 0.62–0.88).
Why this rating
High-quality evidence from a meta-analysis of 93 RCTs with 1.85 million participants, though cancer was a secondary endpoint in most trials.

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
