Weight problems will increase the danger of creating various cancers, so it stands to cause that medication that scale back physique weight also needs to scale back the danger of creating these cancers.
Researchers within the US needed to know if weight-loss medication referred to as GLP-1 agonists diminished the danger of individuals getting any of the 13 cancers related to weight problems. Their outcomes have been lately printed in JAMA Community Open.
GLP-1 is a hormone produced by your intestine after consuming a meal that indicators you’re full. GLP-1 medication ship artificial GLP-1, which is for much longer lasting than the GLP-1 produced by the physique. Current variations of those medication embody Ozempic (used to deal with sort 2 diabetes) and Wegovy (used for weight reduction). However the medication used within the research would have been older variations, resembling liraglutide (Victoza) and dulaglutide (Trulicity).
The researchers within the new research analyzed the well being information of greater than 1.6 million folks with sort 2 diabetes. They in contrast individuals who have been prescribed GLP-1 medication with those that have been prescribed insulin (the usual remedy for sort 2 diabetes) and tried to match the sufferers as intently as attainable to keep away from “bias” (systematic errors within the pattern knowledge).
They discovered that individuals who have been handled with any GLP-1 drug between 2005 and 2018 have been much less more likely to be recognized with ten out of the 13 cancers related to weight problems than those that have been taking insulin.
The danger of cancers together with liver most cancers, pancreatic most cancers, most cancers of the gut (colorectal most cancers) and endometrial most cancers was considerably diminished in contrast with insulin remedy. The danger of breast most cancers, thyroid most cancers and abdomen most cancers was not diminished, however neither was it elevated. The research didn’t report how a lot physique weight was misplaced with GLP-1 medication.
The research additionally in contrast the danger of cancers between GLP-1 medication and one other frequent drug to deal with diabetes, metformin. The outcomes confirmed that GLP-1 medication did not scale back most cancers danger any greater than metformin (metformin has recognized most cancers danger discount properties). The danger of kidney most cancers was, in actual fact, elevated with GLP-1 medication in contrast with metformin.
It is very important be aware that Ozempic was solely authorized within the US in 2017 and Wegovy in 2021. This implies that these medication may solely have been utilized by just a few folks included within the evaluation, on condition that the research interval was 2005-18.
Trigger and impact but to be proved
The research definitively exhibits that folks prescribed GLP-1 medication had a decrease charge of ten particular obesity-related cancers in contrast with folks prescribed insulin for sort 2 diabetes. Nonetheless, it can’t show that the medication precipitated this discount in danger.
To show this, a “potential randomized research” utilizing GLP-1 medication in comparison with placebo must be performed. That is the place individuals are randomly assigned to obtain both a GLP-1 drug or insulin/metformin, after which adopted for a number of years to see who develops most cancers, and what sort.
Different elements that weren’t thought-about within the new research, such because the date of prognosis of sort 2 diabetes, may be accountable for the findings.
Insulin is normally prescribed to sufferers with extra superior types of diabetes and an extended period of diabetes. It can’t be concluded that GLP-1 medication scale back the danger of most cancers in contrast with no remedy. Additionally, it can’t draw any conclusion about Ozempic and Wegovy, on condition that Ozempic was solely authorized a 12 months earlier than the research ended, and Wegovy was not authorized by the point the research concluded.
For the reason that older GLP-1 medication (Victoza and Trulicity), are a lot much less efficient in decreasing physique weight than Ozempic and Wegovy, the impact of the latter medication is perhaps totally different.
Total, the research has executed an necessary job of pointing to a attainable discount of obesity-related cancers in folks utilizing GLP-1 medication in contrast with insulin. Future research, although, ought to attempt to show causality, and the newer GLP-1 medication, resembling Ozempic and Wegovy, ought to be used.
