Screening for Colorectal Cancer With FOBT, Virtual Colonoscopy and Optical Colonoscopy. A Randomized Clinical Trial in the Florence District
Comparison Between Faecal Occult Blood Test (FOBT), Computed Tomographic Colonography (CTC) With Computer Aided Diagnosis (CAD) and Colonoscopy as a Primary Screening Test for Colorectal Cancer. Validation of a Teleradiology Model. Biological Banking in Subjects Recruited for Colonoscopy or CTC.

RATIONALE: Computed tomographic colonography (CTC) has proven to be accurate in detecting colorectal neoplasms and may be a primary test in colorectal cancer screening.

PURPOSE: This clinical trial will compare participation rate, diagnostic yield and costs of computed tomographic colonography, faecal occult blood test (FOBT) and colonoscopy (CO) as a primary screening test in a population-based programme.

OBJECTIVES:

Primary objectives:

  • To compare the participation rate to faecal occult blood test (FOBT), computed tomographic colonography (CTC) and colonoscopy (CO) as a primary screening test in a population-based programme for colorectal cancer.
  • To compare the participation rate to CTC with reduced cathartic preparation versus CTC with standard bowel preparation.
  • To compare the detection rate for cancer or advanced adenomas of CTC with computer aided diagnosis (CAD) versus three rounds of FOBT every second year.
  • To evaluate referral rate for colonoscopy induced by primary CTC versus three rounds of FOBT every second year.
  • To compare costs of the three screening strategies.

Secondary objectives:

  • To compare the expected and perceived discomfort of colonoscopy and computed tomographic colonography as assessed with a structured questionnaire.
  • To evaluate the rate of complications in each group.
  • To validate a teleradiology model for computed tomographic colonography.
  • To create a biological bank of blood and stool specimens from subjects who undergo computed tomographic colonography, primary colonoscopy and second level colonoscopy.

DESIGN:

14,000 subjects aged 55-64 years, living in the Florence District and never screened for colorectal cancer, will be randomized in 3 arms:

  • group 1 (5,000 persons) invited to CTC (divided into: subgroup 1A with reduced cathartic preparation and subgroup 1B with standard bowel preparation);
  • group 2 (8,000 persons) invited to biannual FOBT for 3 rounds;
  • group 3 (1,000 persons) invited to CO.

Subjects of each group will be invited by mail to undergo the selected test. Individuals of each group will receive an invitation letter and an information leaflet, containing information about colorectal cancer, importance of screening, and advantages and possible risks of the selected test.

Invitation letter for the FOBT group contains instructions on how to pick-up the kit test at the nearest pharmacy. The FOBT screening test adopted is OC-SENSOR DIANA (Eiken Chemical Co., Tokyo, Japan), a quantitative, completely automated immunochemical test, based on latex agglutination. Positivity threshold is set at 100 ng/ml of sample solution. Invited subjects are asked to collect a single sample of faeces, without dietary restrictions. Sample are retuned according to the routine procedure of Florence screening programme.

Invitation letter for CTC and colonoscopy contains a phone number and an email address of the screening centre. All invitees have the option to call or send an email to the screening centre in order to receive an appointment for a prior consultation. All non-responders will receive a remainder by mail after three months. Non-responders to reminder will be invited to FOBT according with current screening procedure.

Subjects who accept invitation for CTC or CO will have a consultation at the screening centre with a trained nurse. During the consultation subjects will be informed about the study protocol, the screening examination to which they are invited, the bowel preparation, and the management in case of positive results. All subjects tested positive to FOBT or CTC (mass or at least one polyp ≥ 6 mm) will be invited to undergo total colonoscopy. Then, subjects will be scheduled for the selected examination (CTC or CO).
