Hooked-wire-directed breast biopsy and overpenetrated mammography

Area of Science:

• Oncology
• Radiology
• Surgical Pathology

Background:

• Mammography is a key tool for detecting breast abnormalities.
• Clinically occult lesions require accurate diagnostic methods.

Purpose of the Study:

• To evaluate the diagnostic yield and outcomes of biopsies for mammographically detected, clinically occult breast abnormalities.
• To assess the characteristics and lymph node status of cancers found through screening.

Main Methods:

• Retrospective review of 653 biopsies performed for mammographically detected abnormalities.
• Analysis of cancer detection rates, tumor types (invasive vs. noninvasive), and axillary lymph node status.
• Evaluation of treatment modalities (mastectomy vs. conservative treatment) and complication rates.

Main Results:

• 147 cancers (22.5%) were diagnosed.
• 89 cancers (60.5%) were noninvasive, with no lymph node involvement.
• 6 of 58 invasive cancers (10.3%) showed axillary lymph node metastases.
• Conservative treatment was more common (63.3%) than mastectomy (36.7%).
• Significant complications occurred in only 0.7% of patients.

Conclusions:

• Biopsies for mammographically detected, occult breast lesions have a high cancer yield.
• Noninvasive breast cancers detected via mammography rarely involve lymph nodes.
• Conservative management is frequently feasible and associated with low complication rates for these early-stage breast cancers.
