Blood Pressure Meds May Prolong Life in Pancreatic Cancer

March 7, 2022 — Popular blood stress drugs might add years to the lives of sufferers with pancreatic most cancers, a notoriously tough-to-treat most cancers with low survival charges, new analysis suggests.

These medication, often known as angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs), decrease blood stress by enjoyable veins and arteries and permitting the center to pump blood extra simply.

Studies in animals have proven that these drugs may sluggish the expansion of pancreatic most cancers. Several small research in folks recommend the identical factor, however the numbers of sufferers included have been too small to attract agency conclusions.

In the brand new research, researchers examined information on 3.7 million adults from Italy, and recognized 8,158 folks recognized with pancreatic most cancers between 2003 and 2011.

The research, printed final month within the journal BMC Cancer, discovered that the overwhelming majority of those sufferers (86%) died inside about 6 months of their analysis.

But sufferers who took ARBs after their pancreatic most cancers analysis had a 20% decrease threat of dying, in comparison with related sufferers who didn’t take ARBs.

In a smaller group of sufferers who had surgical procedure for his or her most cancers, ARB customers had a 28% decrease threat of dying.

Also, sufferers with pancreatic most cancers who took ACE inhibitors had a 13% decrease threat of dying within the first 3 years after analysis, however this profit shrank later.

But “ARBs and ACE inhibitors nonetheless must be thought-about experimental therapies for pancreatic most cancers,” cautions research investigator Scott Keith, PhD, of Thomas Jefferson University in Philadelphia.

Timothy Pawlik, MD, PhD, additionally cautions to not soar to agency conclusions based mostly on this research.

“While provocative, the info can’t be thought-about conclusive,” says Pawlik, with the Ohio State University Comprehensive Cancer Center.

“The research is retrospective, which makes it prone to choice and therapy bias. In addition, the info have been derived from an administrative well being care database, which could be infamous for missing granular scientific information,” he factors out.

Pawlik additionally notes that research evaluating the advantages of blood stress drugs on most cancers threat and outcomes is combined. Several earlier research, for example, recommend ACE inhibitors and ARBs might shield towards malignancies comparable to colorectal most cancers, whereas different information suggests a potential hyperlink between ACE inhibitors and a better threat for sure cancers, comparable to lung most cancers.
