Objectives: Screening for colorectal cancer with fecal occult-blood test has been performed in health centers for several years. The aim of this study was to describe participation rate and results in a population attending the Center for preventive medicine at Vandoeuvre-lès-Nancy, France in 1996 and 1997.
Patients and methods: Among 19,325 people aged 50-75 years, the screening test was proposed to 17,917 and performed in 15,527.
Results: Participation rate was 86.7%. Overall positivity was 3.6% higher in men than in women (4.1% versus 3.0%). In the 440 colonoscopies performed, 22 cancers and 84 adenoma polyps were identified (PPV = 24%).
Discussion: These results show good participation rates in a screening program for colorectal cancer during periodic health check-ups. Follow-up for positive subjects was satisfactory but requires good cooperation between specialists and general practitioners to obtain complete information to evaluate the program.
