WEDNESDAY, Jan. 22, 2025 (HealthDay News) — Glucagon-like peptide 1 receptor agonist (GLP-1 RA) use is not associated with an increased risk for thyroid cancer over the short term, according to a study published online Jan. 16 in Thyroid<\/em>.<\/p>\n Sarah M. Baxter, from Queen\u2019s University Belfast in Northern Ireland, and colleagues investigated if GLP-1 RA use compared to use of dipeptidyl peptidase-4 inhibitors (DPP-4is) was associated with thyroid cancer risk in patients with type 2 diabetes. The analysis included 98,147 GLP-1 RA users and approximately 2.49 million DPP-4i users, with a median follow-up ranging from 1.8 to 3.0 years.<\/p>\n The researchers found that GLP-1 RA use was not associated with an increased risk for thyroid cancer (pooled weighted hazard ratio, 0.81; 95 percent confidence interval, 0.59 to 1.12) compared with use of DPP-4i. Among GLP-1 RA ever-users, there was no increased risk in thyroid cancer with an increasing cumulative dose of GLP-1 RA.<\/p>\n “In this large multisite study, utilizing data from six population-based databases, we found no evidence that GLP-1 RA use is associated with an increased risk of thyroid cancer with follow-up ranging from 1.8 to 3.0 years, providing some reassurance to patients and clinicians about the short-term safety of these drugs,” the authors write. “Nevertheless, evidence was insufficient to rule out excess risk with long-term use, due to the short follow-up.”<\/p>\n Several authors disclosed ties to the pharmaceutical industry.<\/p>\n
