Needle localization of nonpalpable breast masses

Area of Science:

• Radiology
• Oncology
• Surgical Oncology

Background:

• Mammography is crucial for detecting nonpalpable breast lesions.
• Accurate preoperative localization is essential for effective surgical management of suspicious findings.

Purpose of the Study:

• To evaluate the efficacy and safety of the hook-wire method for preoperative localization of mammographically detected breast lesions.
• To assess the diagnostic yield and impact on treatment of this localization technique.

Main Methods:

• A retrospective review of 150 preoperative hook-wire localizations in 146 women with mammographically suspicious, nonpalpable breast lesions.
• Analysis of surgical outcomes, including malignancy detection rates and tumor characteristics.

Main Results:

• Carcinoma was diagnosed in 16% of patients (24/146), with 75% being invasive and 25% noninvasive.
• Of patients with calcifications, 24% had malignancies.
• 80% of detected cancers were less than 1 cm, and 38% met criteria for minimal carcinoma.
• Lymph node metastases were present in 14% of carcinoma patients.

Conclusions:

• The hook-wire method is a safe, rapid, and accurate technique for localizing small, potentially curable breast cancers.
• This method allows for minimal breast tissue sacrifice during surgical excision.
• Early detection and precise localization improve treatment outcomes for breast cancer.
