Concordance with breast cancer pathology reporting practice guidelines

Area of Science:

• Oncology
• Pathology
• Surgical Pathology

Background:

• Accurate breast cancer pathology reporting is crucial for effective treatment.
• The College of American Pathologists (CAP) established guidelines for cancer specimen reporting in 1998.
• This study assessed community-wide adherence to CAP breast cancer reporting guidelines.

Purpose of the Study:

• To evaluate the concordance of community hospital pathology reports with CAP guidelines for breast cancer.
• To identify key elements frequently omitted in pathology reports affecting breast cancer treatment.

Main Methods:

• Reviewed 101 pathology reports of Stage I and II invasive breast cancers from community hospitals and Roswell Park Cancer Institute (RPCI).
• Assessed adherence to CAP guidelines for clinically relevant items, including surgical margins, tumor grade, and lymphovascular invasion.
• Included cases from excisional breast biopsies performed between 1998 and 1999.

Main Results:

• Most reports lacked at least one guideline-required element.
• Surgical margins were inked in 77% and oriented in only 25% of cases.
• Bloom-Richardson grade was reported in only 6%, lymphovascular invasion in 57%, and in situ disease extent in 47% of reports.

Conclusions:

• Significant variability exists in breast cancer pathology reporting.
• Essential treatment-related elements, such as margin status and histologic features, are often missing.
• Passive distribution of CAP guidelines may be insufficient for quality improvement in breast pathology reporting.
