Objectives - In 2002 and 2005, 23 departments gradually implemented an organized screening program and invited people aged 50–74 to undergo a Hemoccult® test every two years. The results presented here pertain to the first two-year campaign and the preliminary results of the second campaign. Methods - The data presented come from departmental administrative bodies that transmit the data at the national level to the French Institute for Public Health Surveillance. Results - The participation rate was 42% for the first campaign. The percentage of positive tests was 2.6% (first campaign), 2.9% when, in the second campaign, individuals took the test for the first time, and 2.7% for the second time. In the first campaign, cancer was detected in 3,289 individuals and an adenoma in 10,884 individuals. The rate of detected adenomas was 7.8 per thousand, that of adenomas larger than 1 cm was 3.8 per thousand, and the cancer rate was 2.2 per thousand. Of the 2,504 invasive cancers diagnosed, 23% were of unknown stage, 33% were early-stage cancers (Stage I), 18% of individuals had Stage II cancer, 18% were Stage III (with lymph node involvement), and 8% of individuals had metastatic cancer (Stage IV). Discussion - Conclusion - Participation must improve. In 2008–2009, 98 departments will have implemented organized screening to invite 16 million men and women. (R.A.)
