Abstract

Background

In France, following a pilot population-based screening program in 2002–2003, a national organized program targeting 17 million people was progressively implemented from 2005 to 2009. EDIFICE surveys are iterative polls focusing on cancer screening behavior. The EDIFICE 3 survey was conducted in 2011 and partly dedicated to knowledge of the colorectal cancer screening process.

Methods

This third nationwide observational study, EDIFICE 3, was conducted via phone interviews among a representative sample of 946 subjects aged between 50 and 74 years, who had never been treated for cancer. 59% of the population declared having undergone colorectal cancer screening (fecal test or colonoscopy).

Results

Interviewed about the screening process, 510/946 (54%) of the French population were unaware of the procedure after a positive fecal test and 782/946 (83%) were unaware of how soon a new test should be performed after a negative result. Only 79/946 (8%) were aware of what to do after either a positive or a negative test and 47% in one out of the two cases. 84% of subjects over assessed (by a factor 2 to 10) the probability of having cancer after a positive test. In contrast, 65% were aware of the possibility of a false negative test (neither gender, educational level, socio economic level impacted the knowledge).

Conclusions

This study demonstrates a lack of detailed knowledge on the colorectal cancer screening process in the French national program. This raises the issue of the fairness of the process and may be a reason for the current poor uptake. This should be tackled by improving the transmission of information via general practitioners, institutional letters sent directly to subjects and mass media.
