Can Statins Help Lower Lung Cancer Death Risk?
Small reduction seen with cholesterol-lowering drugs, but study couldn't prove cause-and-effect link
FRIDAY, May 1, 2015 (HealthDay News) -- Taking the cholesterol-lowering medications known as statins for a year before getting a diagnosis of lung cancer was associated with a 12 percent lower risk of dying from that cancer, new research suggests.
The researchers from Northern Ireland also found indications that those who had a minimum of 12 statin prescriptions filled after being diagnosed with lung cancer saw their lung cancer death risk drop by as much as 19 percent.
But, study lead author Chris Cardwell stressed that the degree of the association seen between statin use and a lower risk for lung cancer death was "relatively small."
And while the study found an association between statin use and a lower risk of lung cancer death, it wasn't designed to prove a cause-and-effect relationship.
Cardwell said there are any number of other differences between patients who take statins and patients who don't that might explain the fatality risk drop, rather than statin use itself.
However, Cardwell added that if the study's findings are confirmed, they would build on prior lab and animal research indicating that statins -- and in particular, simvastatin -- may have "potential anticancer effects." Such effects, he noted, could include curbing cancer cell growth and spread, while promoting cancer cell death.
Cardwell is with the Institute of Clinical Sciences Block B and Cancer Epidemiology and Health Services Research Group at Queen's University in Belfast.
The study findings are published in the May issue of Cancer Epidemiology, Biomarkers & Prevention.
Statins are considered a safe and effective way to lower LDL -- the so-called bad type of cholesterol, according to the U.S. National Institutes of Health.
To explore whether or not statins have any impact on lung cancer progression, the study authors reviewed British cancer registry data. They looked at roughly 14,000 British lung cancer patients diagnosed between 1998 and 2009.
About 13,000 who used statins before being diagnosed with lung cancer were included in the study. And approximately 3,600 patients who took statins following their diagnosis were included in the analysis.
