Discovery in fight against bowel cancer

New research has discovered how a genomic approach to understanding bowel (colorectal) cancer could improve the prognosis and quality of life for patients.

Bowel cancer is the fourth most common cancer in the UK, with 41,200 people newly diagnosed each year. A number of treatment options are available but mortality rates remain high, with bowel cancer the second most common cause of cancer death in the UK.

Researchers at Queen’s University Belfast, in collaboration with the University of Oxford and the University of Leeds have made a significant advance in the treatment of bowel cancer. The study, which has been published in the journal Nature Communications, has shown how defining precise gene signatures within bowel cancer cells can allow us to develop novel prognostic and predictive markers for bowel cancer and help to drive personalised medicine approaches.

NICE: All patients with colorectal cancer should be tested for genetic condition

Everyone who has colorectal cancer diagnosed should be tested for an inherited genetic condition called Lynch syndrome, new guidance states | BMJ

The National Institute for Health and Care Excellence (NICE) recommends microsatellite instability testing or immunohistochemistry to detect abnormalities that may indicate the syndrome.

Lynch syndrome, the most common cause of hereditary bowel cancer, has also been linked to an increased risk of developing other cancers including womb, ovarian, and stomach. People with the condition who develop colorectal cancer generally do so at a younger age, usually 40-50.

Testing for the condition helps to identify whether the patient’s family are also at increased risk of cancer so that they can be monitored more closely if needed, says NICE. Where these tests show that a person has a risk of the syndrome, the guidance recommends further tests to confirm the diagnosis. Because it is an inherited condition, a positive test can also lead to testing of family members.

Diagnosing Lynch syndrome may also help with the choice of treatment for colorectal cancer—for example, to direct chemotherapy or surgery.

Simpler bowel cancer test kit a ‘game changer’

Hundreds of thousands more people across England are likely to take up the offer of bowel cancer screening thanks to the introduction of a new and simpler home-testing kit, Public Health Minister Jane Ellison has announced.

It has been estimated that the new test will increase screening uptake by around 10% – meaning an additional 200,000 people could be tested each year. This means that hundreds of lives could be potentially saved, the Department of Health said.

National Bowel Cancer Audit report 2015

The National Bowel Cancer Audit Report 2015 has been published by the Royal College of Surgeons in partnership with the Association of Coloproctology of Great Britain and Ireland.  The report shows that the number of people surviving bowel cancer following major surgery has increased significantly in recent years.  The results presented in this report are based upon patients diagnosed with bowel cancer between 1 April 2013 and 31 March 2014.

A healthy lifestyle before diagnosis may improve bowel cancer survival

UK researchers claim living a healthy lifestyle before diagnosis could improve a person’s chances of surviving bowel cancer.

Findings from Imperial College London suggest eating a balanced diet, keeping physically  active and maintaining a healthy weight were associated with an improved likelihood of survival.

The large European Prospective Investigation into Cancer and Nutrition (EPIC) study, published in BMC Medicine, analysed data from 520,000 men and women from 10 countries over six years. Of these men and women from the study, 3,292 were diagnosed with bowel cancer.

Lead researcher, Dora Romaguera, from Imperial College London wanted to investigate if the same healthy lifestyle choices that help prevent bowel cancer could also improve the survival rates of people diagnosed with the disease.

The study participants completed questionnaires about their medical history, diet and lifestyle at the start of the study, while height and weight measurements were also taken.

Having a healthy weight and high consumption of plant foods had the strongest associations with survival.  There was also an association seen with women who breastfed and improved survival.
