Summary
Wire-guided excision effectively removes abnormal lesions found during screening mammography. This procedure yielded a high positive biopsy rate, confirming malignancy in 64.6% of cases, with 28.6% showing invasive breast cancer.
Area of Science:
- Radiology
- Oncology
- Surgical Pathology
Background:
- Screening mammography detects abnormalities requiring further investigation.
- Wire-guided excision is a common method for localizing and removing non-palpable breast lesions.
Purpose of the Study:
- To review the efficacy of wire-guided excision for abnormal lesions identified on screening mammography.
- To determine the biopsy rate and positive biopsy rate for these procedures.
Main Methods:
- Retrospective review of patients undergoing wire-guided excision of mammographically detected abnormalities.
- Analysis of biopsy results to determine benign versus malignant outcomes.
- Assessment of radiological findings and their correlation with histological diagnoses.
Main Results:
- 65 patients underwent wire-guided excision; 42 lesions (64.6%) were malignant.
- Malignant lesions included ductal carcinoma in situ (30) and invasive breast cancer (12).
- Radiological assessment showed 55% of lesions were suspicious or malignant, correlating with histological findings.
Conclusions:
- Wire-guided excision is a valuable tool for diagnosing and treating mammographically detected breast lesions.
- The procedure demonstrated a high positive biopsy rate, indicating its effectiveness in identifying malignancy.
- A significant proportion of malignant findings required further treatment, highlighting the importance of accurate diagnosis.
