OCCTOPUS – Oxford Colon Cancer Trust

Oxford Colon Cancer Trust is a very practical charity. Our byline is “making new treatments happen”. Whilst national high profile charities fund work on how cancer cells go wrong, OCCTOPUS has a more immediate focus. Originally formed in 2003, it aims to fund practical advances in treatment, education, and research in these areas – the 3 “C’s”: Colorectal cancer, Colitis and Crohns, and Continence.

Anything to do with the bowel is a ‘Cinderella’ subject. It does not have the immediate appeal that heart or children’s disease has for example. The differences in charitable giving for the big four cancers illustrate this. Which is why the generosity of our supporters is so critical.

Such is the speed of progress in this area of surgery that new techniques and high technology equipment are being introduced all the time. Incisions and access to body cavities are becoming smaller and smaller in what is called minimally invasive or key-hole surgery. OCCTOPUS aims to help the colorectal team at the Oxford University Hospitals keep up to date with, and even ahead of these advances. Our patients benefit from the very latest treatment and we educate the surgeons of the future in the most modern procedures.

OCCTOPUS has already raised over £1,000,000 and funded two special key-hole theatres, one at the John Radcliffe and the other more recently at the new surgery and diagnostics centre at the Churchill Hospital. Learn more about our projects.

We seek to fund, and co-fund, with partner organisations, activities which are at the forefront of treatment and cure of the conditions we cover. This may include a pioneering type of procedure which has not become generally accepted or adopted by the NHS as standard:

  • – the purchase of equipment that is required;
  • – the research and analysis of such procedures to provide an evidential base for their benefits and widespread adoption;
  • – provision of training to practitioners worldwide in the undertaking of the procedure

We also consider ad hoc requests for funding of early-stage research ideas and other projects.

The 3 C’s

Colorectal Cancer

Colon DiagramSometimes called bowel cancer this is a very common problem and early cases can be cured with surgery alone. Symptoms include bleeding from the bowel, a change in bowel habit, a lump in the abdomen, and sometimes pain. Patients finding these symptoms will be investigated by colonoscopy or CT colon exam. With the introduction of a national screening programme for bowel cancer there has been a shift from 10% of cases being classed as early to over 40% and this is an opportunity for keyhole or minimally invasive surgery.

The anatomy of the colon is shown on the right, and during surgery, a section of the colon is removed and usually rejoined. After the pathologist has examined the removed colon and especially any lymph glands a decision is made about postoperative chemotherapy.

For more information see the Cancer Research UK website www.canceresearchuk.org

Colitis and Crohns disease

These two diseases are often clumped together as IBD or inflammatory bowel disease.
They cause ulceration and narrowing of the bowel. If surgery is needed major procedures are required which are especially suitable for keyhole applications since the patients are young and want to avoid long incisions and return to normal activity as soon as possible.

For more information see the NACC website



The colon and rectum and indeed the rest of the intestinal tract cannot function well unless the pelvic floor works properly. Delicate mechanisms control continence, and although these are often not consciously appreciated when they go wrong there can be a huge effect on quality of life.
