Common Sense Reporting of Colorectal Adenocarcinoma in Endoscopically Obtained Samples

Area of Science:

• Gastroenterology
• Surgical Pathology
• Oncology

Background:

• Numerous histologic prognostic features are recommended for colorectal carcinomas in endoscopic specimens.
• Data on their utility in polypectomy specimens are limited and often derived from surgical specimens.
• Information may be incremental and more accurate when provided by the endoscopist than the pathologist.

Purpose of the Study:

• To provide evidence-based practice points for pathology reporting of colorectal carcinomas in endoscopic specimens.
• To simplify pathology reports while retaining essential information for patient management.
• To address the limitations of current reporting practices for polypectomy specimens.

Main Methods:

• Review of existing literature and data on histologic prognostic features in colorectal carcinoma specimens.
• Analysis of the utility and accuracy of these features in polypectomy versus surgical specimens.
• Development of practice points based on evidence to guide pathology reporting.

Main Results:

• Current recommendations for numerous prognostic features in endoscopic specimens may not be fully applicable or beneficial.
• Reporting biopsy samples as "at least high-grade dysplasia/intramucosal carcinoma" may misrepresent biologic risk.
• Simplified reporting with key information can guide patient management effectively.

Conclusions:

• Pathology reports for colorectal carcinomas in endoscopic specimens can be simplified.
• Evidence-based practice points can streamline reporting without compromising patient care.
• Focusing on essential features ensures accurate assessment of biologic risk and guides appropriate management.
