According to foreign media reports, the United Kingdom will start the world's largest clinical trial toxicity test of the aspirin efficacy. About 11,000 people who have early colorectal cancer, breast cancer, prostate cancer, gastric cancer and esophageal cancer will be involved in this experiment.
In the last few years, the debate over whether aspirin has an effect on cancer has become more intense because of its uncertainty. Scientists say that if the effect of the drug on disease model is to be confirmed, it will bring revolutionary changes to provide a cheap and effective treatment for cancer patients.
The clinical trial is jointly funded by the UK charity Cancer Research Center and the National Institutes of health, and the patients will take an aspirin every day for 5 years. The researchers will compared patients with different doses who are treated with false drugs (placebo) to examine whether the cancer has a recurrence.
"This clinical trial is particularly exciting because cancer recurrence is often difficult to cure, so finding a cheap and effective way of fighting cancer is likely to bring a revolutionary change to the sick," says Dr. Fiona Reddington of the UK cancer research center.
This clinical trial will be conducted in the UK's 100 medical institutions. Many patients and some who have been cured of early cancers will be involved. This experiment will continue for 12 years. Taking drugs every day also brings a series of health problems, because it may bring side effects, such as stomach ulcers and stomach bleeding, etc..
"There have been some interesting studies that have shown that aspirin can delay or prevent the recurrence of early cancers," says Ruth Langley, the lead researcher at the experiment. The purpose of this experiment is to solve the problem.
"If our study shows that aspirin does prevent cancer, it can completely change the future treatment and provide a simple and inexpensive way to prevent cancer from recurring," Ruth said."
Alex King was diagnosed with breast cancer in December 2009 with age of 51, and has now been cured. He said: "cancer is the worst of my life experience and anything which can reduce the chance of cancer recurrence is very important." Many people now take a small dose of aspirin as a kind of heart disease drugs every day.
