However, the causal relationship of GLP1R agonists (GLP1RA) with cancers still unclear.  \nMethods: The available cis-eQTLs for drugs target genes (GLP1R) were used as proxies for exposure to GLP1RA. Mendelian randomizations (MR) were performed to reveal the association of genetically-proxied GLP1RA with 14 common types cancer from large-scale consortia. Type 2 diabetes was used as positive control, and the GWASs data including 80 154 cases and 853 816 controls. Replicating the findings in the FinnGen study and then pooled with meta-analysis. Finally, all the related randomized controlled trails (RCTs) on GLP1RA were systematically searched from PubMed, Embase, and the Cochrane Library to comprehensively synthesize the evidence to validate any possible association with cancers.  \nResult: A total of 22 significant cis-eQTL single-nucleotide polymorphisms were included as genetic instrument. The association of genetically-proxied GLP1RA with significantly decreased type 2 diabetes risk [OR (95%) = 0.82 (0 .79–0.86), P \u003C 0.001], which ensuring the effectiveness of identified genetic instruments. The authors found favorable evidence to support the association of GLP1RA with reduced breast cancer and basal cell carcinoma risk [0 .92 (0 .88–0.96), P \u003C 0.001, 0 .92 (0 .85–0.99), P = 0.029, respectively], and with increased colorectal cancer risk [1 . 12 (1 .07–1. 18), P \u003C 0.001] . In addition, there was no suggestive evidence to support the association of GLP1RA with ovarian cancer [0 .99 (0 .90–1.09), P = 0.827], lung cancer [1 .01 (0 .93–1. 10), P = 0760], and thyroid cancer [0 .83 (0 .63–1. 10), P = 0. 187] . Our findings were consistent with the meta-analysis. Finally, 80 RCTs were included in the systematic review, with a low incidence of different kinds of cancer.  \nConclusions: Our study suggests that GLP1RA may decrease the risk of breast cancer and basal cell carcinoma, but increase the risk of colorectal cancer. However, according to the systematic review of RCTs, the incidence of cancer in patients treated with GLP1RA is low. Larger sample sizes of RCTs with long-term follow-up are necessary to establish the incidence of cancers and evaluate the risk-benefit ratios.  \nKey words: cancers, drug target, GLP1R agonists, Mendelian randomization  \nIntroduction  \nSemaglutide, an agonist of glucagon-like peptide-1 receptor (GLP1R), was originally developed for the treatment of type 2 diabetes, and has been granted supplemental approved by the  \nU.S. Food and Drug Administration (FDA) on 4 June 2021 for use in obese and overweight adult[1] .
