In 400 BC aspirin was first used by Hippocrates. Acetylsalicylic acid is the fabric name of aspirin, which originates from the bark of a willow tree.
In 1898 the drug was introduced as a painkiller in high dose (500 mg). In the 1970 ’s aspirin became indicated as therapy for cardiovascular prevention. In the trials studying aspirin as indication for cardiovascular prevention it was observed that patients with colorectal cancer taking aspirin have an improved survival compared to patients who do not take aspirin. As a result of this finding, many epidemiological and molecular retrospective studies have been published in the past years(1-3) mainly in the field of colorectal cancer.
Epidemiological studies show a very consistent 40 percent risk reduction of death due to cancer and overall survival.
Now the time has come to verify these data in randomised clinical trials to really assess aspirin as an optional treatment for cancer.
