Scientific titleColorectal cancer screening by quantitative analysis of DNA isolated from exfoliated cells sampled from the surface of human rectal mucosa: A case-control study
Study acronymVTD/PTO
Study objectivesCell exfoliation from the surface of colorectal tumours is much more intensive than from normal colorectal mucosa. The hypothesis is that exfoliated cells are transferred to the rectum within mucocellular layer separating colon mucosa from the gut contents, and accumulation of exfoliated cells in cancer patients is much greater comparing to healthy individuals. It is suggested that this phenomenon can be used for colorectal cancer early detection and screening.

Please note that another trial closely related to this study has been registered with ISRCTN30255103 (http://www.controlled-trials.com/ISRCTN30255103)
Ethics approval(s)1. Oxford Research Ethics Committee. Date of approval: 15/02/2006 (ref: 06/Q1605/21)
2. South West Surrey Local Research Ethics Committee. Date of approval: 12/04/2006 (Amendment 4 to ref: 04/Q1909/38)
Health condition(s) or problem(s) studiedColorectal cancer
InterventionThis study was conducted with two distinct groups of participants:
1. Patients with clinical diagnosis of colorectal malignancies
2. Clinically healthy volunteers

In this case-control study both cancer patients and healthy volunteers provided samples for the analysis of DNA scores.

Interventions:
Samples of exfoliated cells were collected from the surface of rectal mucosa using proctoscopy and a short (10 sec) inflation in the rectal cavity of a cell-collecting balloon. The procedure was minimally invasive and was completed within five minutes. The collected samples were assessed for DNA contents.
Intervention typeOther
Primary outcome measureDNA yields from exfoliated materials (DNA scores) are assessed in terms of their predictive value in detecting the presence of colorectal cancer
Secondary outcome measuresNo secondary outcome measures
