Summary
Image-guided percutaneous core needle biopsy is an accurate, cost-effective breast lesion diagnostic tool. Most benign diagnoses avoid surgery, but high-risk findings may necessitate surgical biopsy.
Area of Science:
- Radiology
- Pathology
- Oncology
Background:
- Percutaneous core needle biopsy (PCNB) is a key diagnostic method for breast lesions.
- Accurate diagnosis guides patient management, potentially avoiding unnecessary surgical procedures.
Purpose of the Study:
- To evaluate the accuracy and clinical utility of imaging-guided PCNB for indeterminate breast lesions.
- To determine factors influencing the choice of guidance (sonographic vs. stereotactic) and biopsy probe characteristics.
Main Methods:
- Review of imaging-guided PCNB techniques, including sonographic and stereotactic guidance.
- Analysis of factors affecting diagnostic accuracy, such as lesion characteristics and tissue volume retrieved.
- Assessment of complication rates and concordance between biopsy results and clinical/imaging findings.
Main Results:
- PCNB is accurate and cost-effective for diagnosing indeterminate breast lesions and confirming suspected carcinoma.
- Sonographic or stereotactic guidance may be preferred based on lesion location and imaging features; probe size is generally not critical.
- Larger tissue volumes improve diagnosis for calcifications, atypical ductal hyperplasia (ADH), and ductal carcinoma in situ (DCIS).
Conclusions:
- Imaging-guided PCNB allows most patients with benign findings to avoid surgery.
- Surgical biopsy is indicated when benign histology is discordant with imaging, high-risk lesions are identified, or a definitive diagnosis cannot be made.
- Current PCNB techniques are diagnostic, not therapeutic, for breast carcinoma.
