Summary
The first population-based breast cancer screening program in France, initiated in Rhône in 1987, demonstrates satisfactory short-term results with a 50% acceptance rate and a 6 per 1000 cancer detection rate.
Area of Science:
- Oncology
- Public Health
- Radiology
Background:
- France is progressively implementing nationwide systematic breast cancer screening.
- The Rhône department initiated its population-based breast cancer screening program in 1987.
Purpose of the Study:
- To describe the first population-based breast cancer screening program in France.
- To evaluate the initial outcomes of the Rhône breast cancer screening program.
Main Methods:
- Women aged 50-70 in Rhône are invited for single-view mammography every three years.
- Mammograms are interpreted through double reading organized by l'Association des Radiologues du Rhône pour le Dépistage des Maladies du Sein (ARRADEMAS).
- Program evaluation utilizes data from the screening information center and the local breast cancer registry.
Main Results:
- After seven years, the program shows a 50% acceptance rate and an 8% recall rate.
- The prevalent screen biopsy rate is 1.3%, with a detection rate of 6 per 1000 women.
- The program's information system successfully collects data for all invited women, not just those screened.
Conclusions:
- The initial phase of the Rhône breast cancer screening program has met its short-term objectives.
- The program effectively collects comprehensive data for monitoring and evaluation.
- Population-based screening programs can achieve satisfactory participation and detection rates.
