Summary
This study analyzed discrepancies between mammography and pathology for nonpalpable lesions. Recommendations include enhanced pathologist review and tissue block radiography to improve diagnostic accuracy.
Area of Science:
- Radiology
- Pathology
- Oncology
Background:
- Mammography is a key screening tool for breast cancer.
- Accurate pathologic examination of biopsied lesions is crucial for diagnosis.
Purpose of the Study:
- To evaluate discrepancies between mammographic findings and final pathologic diagnoses for nonpalpable breast lesions.
- To identify causes of these discrepancies and propose solutions.
Main Methods:
- Prospective study of 277 patients undergoing 291 mammographically directed biopsies.
- Analysis of discrepancies in calcification detection between mammography/radiography and pathology.
Main Results:
- 7.1% of calcified lesions on imaging were not identified as calcified by pathology.
- 6.6% of non-calcified lesions on imaging were identified as calcified by pathology.
- Discrepancies attributed to sampling, pathologist description, oxalate crystals, and tissue processing.
Conclusions:
- A protocol involving comprehensive histologic review, polarizing lenses, and tissue block radiography is recommended.
- This protocol aims to minimize diagnostic errors and improve accuracy in breast lesion diagnosis.
