Key gaps in pathologic reporting for appendiceal mucinous neoplasms: time for universal synoptic reporting?

Area of Science:

• Gastrointestinal Pathology
• Surgical Pathology
• Oncology

Background:

• Appendiceal mucinous neoplasms (AMN) prognosis depends on histopathology.
• Current classification schemes group diverse tumor behaviors, complicating clinical interpretation.
• Accurate histopathology is vital for patient management and counseling.

Purpose of the Study:

• To evaluate the completeness of essential histologic features in pathology reports for AMN.
• To identify deficiencies in reporting that impact clinical decision-making.
• To assess the utility of synoptic reporting for AMN.

Main Methods:

• Retrospective review of 69 appendectomy specimens diagnosed with AMN (2002-2015).
• Analysis of internal and external pathology reports for 5 key items: invasion, mucin, perforation, margins, and implants.
• Comparison of completeness between standard and synoptic reports.

Main Results:

• External reports were incomplete for all essential items in 81.5% of cases.
• Internal reports were incomplete for all essential items in 82.6% of cases.
• Synoptic reports demonstrated higher completeness for key items compared to non-synoptic reports.

Conclusions:

• Most pathology reports for AMN lack critical information for patient management.
• Synoptic reporting enhances the completeness of pathology reports for appendiceal mucinous neoplasms.
• Standardizing reporting is necessary for improved patient care.
