Study Details

Study Description

Brief Summary

The effect of mailing FIT with the invitation on participation and colonoscopy rates will be evaluated in a randomized controlled trial conducted in the Centre-Val de Loire (CVL) region, involving 64,000 people from the population eligible for colorectal cancer population-based organised screening program (CRC-PBOSP).

In the "C" control group, invitations, test delivery and reminders will be carried out in accordance with the CRC-PBOSP rules at the time of the study.

Intervention group "B" will evaluate two experimental modes of invitation with direct home mailing of the test:

  • Method "B1": invitation with test sent to home without prior information letter

  • Method "B2": information letter followed by invitation with test sent home, designed to optimize participation by first-time subjects (aged 50-51) invited to the CRC-PBOSP for the first time.

Ancillary studies will focus 1/ on acceptability of this intervention (qualitative study on a few general practitioners, gastroenterologists and invitees), 2/ on social and geographical inequalities of participation on a subsample of individuals included in EXPEDIT study using ecological indices (EDI, SCALE).

Condition or Disease Intervention/Treatment Phase

Arms and Interventions

Arm Intervention/Treatment
Other: Control "C"

Usual care : Screening test (Fecal immunochemical test - FIT) delivery and reminders will be carried out in accordance with the Colorectal cancer population-based organised screening program (CRC-PBOSP) specifications at the time of the study. This arm is suitable for both the first screening round in 50-51 years old population, and for the subsequent screening rounds.

Other: CRC screening invitation not including the screening test.
The invitation to CRC-PBOSP will only contain informations on how to get the screening test.

Experimental: Intervention "B1"

FIT mailed at home within the CRC screening invitation without prior information letter. This arm is suitable for both the first screening round in 50-51 years old population, and for the subsequent screening rounds.

Other: Mailing of FIT with invitation
The invitation to CRC-PBOSP will contain the CRC screening test.

Experimental: Intervention "B2"

FIT mailed at home within the CRC screening invitation with prior information letter. This arm is suitable for the first screening round in 50-51 years old population only.

Other: Mailing of FIT with invitation
The invitation to CRC-PBOSP will contain the CRC screening test.

Other: Information letter before invitation
An information letter will be sent to future invitees a few weeks before the invitation, to announce the mailing of the CRC screening kit.

  4. Time to colonoscopy (in FIT positive patients) [12 months after the positive test]

    Time from FIT to colonoscopy within 12 months of positive FIT among invitees with a positive FIT

  5. Colonoscopy findings [12 months after the positive test]

    Rate of colorectal cancer or advanced neaplasia in invitees with a positive FIT

  6. Participation to CRC screening program in first invitees (50-51 yrs-old) [16 months after invitation]

    Rate of FIT sent to laboratory for analysis within 16 of months of invitation among first invitees (50-51 yrs-old)

  7. Cost-effectiveness analysis [24 months]

    Costs of CSC-PBOSP from invitation to colonoscopy when necessary
