A new study has stated that giving aspirin to colon cancer survivors may help the patient in living longer.
According to previous studies, administering aspirin to patients after they were diagnosed with colon cancer helped in living them longer. But the new study is not able to explain the exact working behind this.
Author of a commentary accompanying the study Dr Alfred Neugut said the study reiterates the fact that aspirin is helpful for certain colon cancer patients.
Thus, the study said that the benefit of taking aspirin was seen in patients whose tumours made HLA class I antigen protein. This antigen may be playing a role in the immune system's response to cancer cells, the researchers said, adding that further research was required.
"If our results are confirmed by others and aspirin is studied as a treatment in a proper phase three randomised trial, then we would have a valid new anti-cancer treatment that is both safe and cheap," said study author Gerrit Jan Liefers of Leiden University Medical Center in the Netherlands.
In the US, colon cancer is the fourth most common type of cancer.
As part of the study, researchers analysed tissue from tumours from 999 colon cancer patients who had been operated upon between 2002 and 2008. Out of these 999, 182 used aspirin and 69 of these died by January 2012. And out of 817 patients who didn't take aspirin, 396 died.
But Liefers said that the study does not prove that people with colon cancer should start taking aspirin.
