Clinical developments in cancer treatment
- Combined multi-modality treatment
- neoadjuvant therapy ( disease downstaging )

- New surgical techniques for colon cancer

Colorectal cancer screening
Rationale
- Natural history
- Most cancers arise from benign adenomas
(adenoma-carcinoma sequence)
- Adenomas removed / destroyed with
flexible sigmoidoscope / colonoscope
Colorectal cancer screening
Types
- Faecal occult blood testing *
- Flexible sigmoidoscopy *
- Double contrast barium enema
- Colonoscopy – GOLD STANDARD!
- Virtual colonoscopy ?
Future ?
- Genetic markers in blood / stool
(Detection of colorectal cancer by DNA quantification of exfoliated colonocytes) Bajwa et al; DCR 2008
Evidence (FOBT)
- randomised trial (Nottingham / Denmark)
- 150,000; 45-74yrs; 360 vs 420 deaths
- 15% decrease in cumulative survival in
the non-screened population
Colorectal cancer screening
Pilot Screening Statistics
- 25,000 in screening population
- 65% will return kit (16250)
- 2% will be abnormal (325)
- Of these
– 162 will be normal at colonoscopy – 130 will have polyps – 33 will have cancer

National bowel cancer screening National bowel cancer screening with flexible with flexible sigmoidoscopy sigmoidoscopy
- Single flexible sigmoidoscopy at 55 years
- Pilot trials – late 2012
- National roll out 2014, complete by 2016
- Age 60-74 (2 yearly FOBT screening)
- Existing screening centres to oversee
- New centres for FSST must be JAG accredited
- Personnel (Nurses/ Medical / Surgical Registrars
- Accreditation process for personnel unclear *
UCLH & FSS
Where are we now?
- Age extension (September 2012)
- 2013 – proposals to pilot FSS
- 2014 – FSS at UCLH / surrounding trusts
Conclusion
- Bowel cancer screening saves lives. 70% of screen detected
cancer is early stage disease potentially curable at endoscopy
- r surgery.
- UCLH is a leader in modern colorectal cancer therapy
- ffering a multidisciplinary evidenced based approach to
patient management
- Through research and pioneering work, UCLH has
contributed to some of the new exciting clinical developments in colorectal cancer.
- Future introduction of FSS at UCLH will reduce the
