This work aims to test the use of the CanSense blood test for the longest waiting colonoscopy surveillance patients in Swansea Bay University Health Board. 200 longest-waiting patients will be offered the CanSense test which will assess them as being either at high or low risk of having polyps or cancer. It will seek patient and provider evidence for the value of the streamlined approach rather than a ‘longest waiter first’ approach.

The project will:

  • Measure the value of incorporating the test in the pathway.
  • Evaluate whether the CanSense blood test provides superior prediction of colonoscopy findings than clinical validation alone.
  • Evaluate whether the CanSense prioritisation strategy is more acceptable than clinical validation as measured through patient and clinician reported experience surveys.
  • Provide evidence for a scalable solution for endoscopy units across Wales.
