GLP-1 Receptor Agonists Reduce Risk of Obesity-Associated Cancers

GLP-1 Receptor Agonists Reduce Risk of Obesity-Associated Cancers

A recent retrospective analysis of electronic health records suggested that GLP-1 receptor agonists could potentially lower the risk of several obesity-associated cancers. This study compared the use of GLP-1s with insulin in individuals with type II diabetes and found a lower risk for developing 10 out of 13 cancers. These findings open up new possibilities for cancer prevention and highlight the potential benefits of GLP-1 receptor agonists in managing diabetes and weight loss.

The follow-up period in the study spanned up to 15 years and revealed significant risk reductions for various cancers when using GLP-1 receptor agonists. Some of the specific risk reductions included:
– Gallbladder cancer
– Meningioma
– Pancreatic cancer
– Hepatocellular carcinoma
– Ovarian cancer
– Colorectal cancer
– Multiple myeloma
– Esophageal cancer
– Endometrial cancer
– Kidney cancer

When compared with metformin, GLP-1 receptor agonists did not show a decrease in cancer risk. However, in comparison with insulin, GLP-1s exhibited a lower risk for developing multiple types of cancer. The study also observed a trend towards reduced risk for stomach cancer with GLP-1s, although it did not reach statistical significance. Interestingly, GLP-1s were not associated with a decreased risk of postmenopausal breast cancer or thyroid cancer.

The study sheds light on the potential of GLP-1 receptor agonists in preventing obesity-associated cancers. With the increasing use of newer GLP-1 agonists like semaglutide and tirzepatide, the importance of further research in this area is emphasized. However, the study also highlighted an increased risk of kidney cancer with GLP-1 treatment compared to metformin. This finding underscores the need for continued monitoring of patients undergoing GLP-1 receptor agonist therapy.

The analysis was based on electronic health records of over 1.6 million U.S. patients with type 2 diabetes who were prescribed GLP-1 receptor agonists, insulin, or metformin over a 13-year period. The patient population was diverse in terms of age, race, and gender, with a majority being white and male. However, the study did not control for healthcare utilization or insurance type, which may have influenced the results.

The study suggests that GLP-1 receptor agonists have the potential to reduce the risk of developing obesity-associated cancers in individuals with type II diabetes. While further research is needed to understand the mechanisms behind this risk reduction, the findings open up new avenues for cancer prevention and management in diabetic patients.
