Breast pathology review: does it make a difference?

Area of Science:

• Pathology
• Oncology
• Surgical Management

Background:

• Breast pathology diagnoses can have discrepancies, even among experts.
• Accurate diagnosis is critical for appropriate surgical management of breast disease.

Purpose of the Study:

• To determine if mandatory pathology review impacts breast disease diagnosis and surgical management.
• To evaluate the rate of diagnostic and management changes following expert pathology review.

Main Methods:

• Expert breast pathologists reviewed 430 biopsy specimens from 306 patients over two years.
• Compared initial diagnoses and surgical management plans with second opinion reports.
• Analyzed changes based on initial diagnosis, specimen type, and originating institution.

Main Results:

• Seventy-two cases (17%) had diagnostic changes, and 41 (10%) had surgical management changes.
• Diagnostic changes were more frequent for initially benign diagnoses (31%) compared to malignant (7%).
• Twelve benign diagnoses were reclassified as malignant; 4 malignant diagnoses were reclassified as benign.

Conclusions:

• Breast pathology review is recommended based on clinical scenarios, irrespective of the initial diagnosis or institution.
• Expert review can identify significant diagnostic and management discrepancies.
• Consideration of pathology review can improve patient care in breast disease.
