[Edifice program: analysis of screening exam practices for cancer in France]

The practices of screening and the parameters influencing these practices are not well known in France. The objectives of the Edifice study were to analyze a large cohort of patients and doctors in order to further characterize these parameters.

The study was performed by the Institute TNS Healthcare-SOFRES, and included 2 parallel studies: 1) on 1 609 healthy persons representative of the global French population and aged 40 to 75 years (N = 1 509), with an over representation of patients aged 50 to 74 years living in the 22 pilot French departments pilots; 2) on 600 generalist practitioners. Data were collected and analyzed by the expert panel...

Ninety-three, 25, 36 and 6% of the patients in the general population declared to have performed at least one a screening exam for breast, colon, prostate, and lung carcinoma respectively. Seventy, 20, 60 and 4% of GP declare to propose systematically to a 40-75-year-old patient a screening test for breast, colon, prostate, or lung cancer. For breast cancer screening the adhesion of the GP is independent of the date of implementation of a general screening in their own regions, while for colorectal screening, 34 and 20% of the patients living in the pilot versus other departments were screened. Overall, prostate cancer screening is recommended by the GP panel for 77.1% of patients aged 50 to 75 years.

This study shows a good adhesion of screening procedures for GP and patients, shows that screening is improved by general screening policy in colorectal cancer, but that prostate cancer screening practices exceed what is recommended according to evidence based medicine.
