Stereotaxic core breast biopsy (SCBB) is a reliable method for evaluating mammographic lesions. However, caution is advised for benign results, as 25% of these specimens were inadequate.
Area of Science:
- Radiology
- Pathology
- Breast Imaging
Background:
- Stereotaxic core breast biopsy (SCBB) is a proposed cost-effective method for evaluating mammographic lesions.
- This study assesses initial SCBB experiences and specimen adequacy.
Purpose of the Study:
- To evaluate the adequacy of breast biopsy specimens obtained through SCBB.
- To assess the reliability of SCBB in a clinical setting.
Main Methods:
- 241 SCBB procedures were performed on 221 patients over 13 months by four radiologists.
- Mammograms received a suspicion index (1-5).
- A pathologist retrospectively reviewed specimens for adequacy (quality and quantity).
Main Results:
- 77% of all SCBB specimens were deemed adequate.
- 100% of malignant specimens were adequate, compared to 74% of benign specimens.
- Adequacy was lower (62%) for benign specimens without specific features.
Conclusions:
- SCBB is primarily used by surgeons for indeterminate mammographic lesions.
- A significant proportion (25%) of benign SCBB specimens were inadequate.
- Benign SCBB results require cautious interpretation due to potential inadequacy.
