Rethinking certainty: a retrospective study on diagnostic revisions in gynecologic pathology

Area of Science:

• Gynecologic Pathology
• Oncology
• Diagnostic Accuracy

Background:

• Expert pathology review is vital in gynecologic oncology due to diagnostic complexity.
• Pathology diagnoses significantly influence patient management and medico-legal outcomes.

Purpose of the Study:

• To evaluate the frequency, nature, and impact of diagnostic revisions from second opinion pathology reviews in gynecologic lesions.
• To assess the clinical and medico-legal significance of these revisions.

Main Methods:

• Retrospective analysis of 319 gynecologic lesion cases undergoing second opinion review.
• Categorization of cases into concordant, minorly discrepant, or majorly discrepant diagnoses.
• Systematic evaluation of clinical impact and medico-legal relevance.

Main Results:

• Major discrepancies (34.5%) and minor discrepancies (18.5%) were observed in over half of the reviewed cases.
• Disagreements most commonly involved tumor histotype, grade, and primary site determination, particularly in ovarian and endometrial specimens.
• Revisions altered clinical management in 54.9% of cases and had potential medico-legal implications in 11.3%.

Conclusions:

• Expert second opinion pathology in gynecologic oncology demonstrates a high rate of significant diagnostic revisions.
• Routine specialist review for complex or high-risk gynecologic lesions is recommended to enhance diagnostic accuracy and patient care.
• Implementing specialist review can mitigate diagnostic errors and reduce medico-legal risks in gynecologic oncology.
