Summary
Stereotactic core-needle biopsy (SCNB) is a safe and effective outpatient procedure for diagnosing nonpalpable breast lesions. This minimally invasive technique accurately identifies malignancies with a 12% cancer rate, offering a cost-effective alternative to open biopsy.
Area of Science:
- Radiology
- Surgical Oncology
- Pathology
Background:
- Stereotactic localization and biopsy using fine needle and 14-gauge core needle is an emerging diagnostic technique for nonpalpable breast lesions.
- This procedure utilizes specialized equipment for precise localization and sampling of subtle breast abnormalities.
- Accurate diagnosis of nonpalpable breast lesions is crucial for timely intervention and improved patient outcomes.
Purpose of the Study:
- To evaluate the efficacy and outcomes of stereotactic core-needle biopsy (SCNB) in a clinical setting.
- To determine the malignancy rate and diagnostic accuracy of SCNB for nonpalpable breast lesions.
- To assess the feasibility and patient experience associated with SCNB compared to traditional methods.
Main Methods:
- A retrospective analysis of 300 consecutive stereotactic core-needle biopsies (SCNB) performed by a surgical group.
- Procedures were conducted over a 13-month period, focusing on the accurate localization and sampling of nonpalpable breast abnormalities.
- Data collection included diagnostic outcomes, malignancy rates, and comparison with established literature.
Main Results:
- The study identified 37 cancers among the 300 SCNB procedures, resulting in a malignancy rate of 12%.
- Specific cancer types included 7% infiltrating ductal carcinoma and 4% ductal carcinoma in situ, with additional cases of adenocarcinoma and mucinous carcinoma.
- Benign diagnoses comprised fibrocystic changes (193), fibroadenomas (34), benign breast tissue (19), and other findings (12), with 5 suspected malignancies ultimately proven benign.
Conclusions:
- Stereotactic core-needle biopsy (SCNB) is a virtually painless, brief outpatient procedure with lower costs than open biopsy.
- The technique is easily mastered by surgeons and yields diagnostic results comparable to controlled studies.
- SCNB demonstrates similar malignancy detection rates to the group's prior experience, supporting its clinical utility.
