Article Synopsis
- The study evaluates how accurately ICD-9-CM codes identify new cases of carcinoma in situ and invasive breast cancer in three Italian regions.
- Sensitivity and specificity of these codes were assessed against medical charts, showing high accuracy rates, especially for invasive breast cancer (up to 100% sensitivity in some regions).
- The findings suggest that these administrative databases can effectively identify patients with breast cancer, facilitating research on new cases using the defined criteria.
