TUESDAY, Aug. 31 (HealthDay News) -- There's no evidence that
popular cholesterol-lowering statins cause cancer, says a review that
challenges earlier research raising concerns that the drugs may be
associated with an increase in cancer and cancer-related deaths.
The findings should reassure the millions of people worldwide who take
the drugs, said the researchers at the University of Oxford in the U.K.
and the University of Sydney in Australia.
They examined data from 170,000 people who took part in 26 randomized
and controlled clinical trials. Of those participants, more than 10,000
developed cancer and more than 3,500 died from cancer. The analysis showed
that the cancer death rates were the same in people taking statins and in
those who took a placebo.
The analysis also found that no difference in cancer risk between a
higher statin dose and a standard dose.
The study was presented recently at the European Society of Cardiology
(ESC) Congress in Stockholm.
"Statin therapy had no adverse effect on cancer at any site [in the
body] or in any group of individuals, irrespective of their cholesterol
levels. There was also no association of cancer with statin dose or
duration," noted Dr. Jonathon Emberson, senior statistician at the
University of Oxford.
The researchers found there was no evidence that statins were linked to
particular types of cancer, such as breast cancer, or to particular groups
of people, as earlier studies had suggested.
"These findings are extremely reassuring for patients," co-principal
investigator Professor Rory Collins, a professor of medicine and
epidemiology at the University of Oxford, said in an ESC news release.
"Statins are one of the most effective known therapies for the prevention
of heart attacks and strokes, and this study should reassure the millions
of people who are taking them worldwide."
The study was funded by the UK Medical Research Council, the British
Heart Foundation and the National Health and Medical Research Council
(Australia), and involved collaborators from around the globe.
