Aspirin boost for gastrointestinal cancer patients

Aspirin can double the life expectancy of patients with cancers affecting the gastrointestinal tract, a major study has found.

Men & women with a range of cancers who took the anti-inflammatory pain killer experienced a "significant" survival benefit compared with those who did not.

Researchers analysed data from nearly 14,000 patients in the Netherlands, around half of whom were in the habit of taking aspirin.

Over a typical follow-up period of four years, those using the drug after their diagnosis were twice as likely to still be alive as non-users.

The impact of aspirin on survival was seen after adjusting for factors such as gender, age, stage of cancer, treatments, & other medical conditions that could have influenced death rates.

Trial co-ordinator Dr Martine Frouws, from Leiden University in the Netherlands – who presented the findings at the 2015 European Cancer Congress in Vienna, said: "Now we would like to analyse tumour material from these patients to try & discover which ones would benefit from aspirin treatment.

"Through studying the characteristics of tumours in patients where aspirin was beneficial, we should be able to identify patients who could profit from such treatment in the future.

"Given that aspirin is a cheap, off-patent drug with relatively few side-effects, this will have a tremendous impact on healthcare systems as well as patients."

The most usual tumour sites for patients in the study were the colon, rectum & oesophagus.

A new randomised controlled trial is currently investigating the effect of a daily low dose of 80 milligrams of aspirin on the survival of elderly patients with bowel cancer in the Netherlands.

In this trial, the effects of aspirin & a dummy "placebo" will be compared. Researchers, who plan at a after date to expand the study to include gastrointestinal cancers, hope to provide "convincing proof" that more patients can benefit from aspirin treatment.

Professor Peter Naredi, scientific co-chair of the Congress, said: "We have satisfactory evidence that the frequent use of aspirin in the population can prevent some cases of colorectal (bowel) cancer. Now, Dr Frouws & colleagues show that in over 13,000 patients who were diagnosed with a gastrointestinal cancer, aspirin moreover improved survival compared with those who did not use it.

"With more & more data to support the beneficial role of aspirin, we must consider whether we should recommend it to a wider public."
