Description

SC18-Diagnostic Criteria of The Paris System for Reporting Urinary Cytology: An Outcomes and Risk Based System

Session Credits: 3 CME and 3 SAMs

Faculty: Dorothy L. Rosenthal, MD, FIAC, Christopher J. VandenBussche, MD, Matthew T. Olson, MD, Guliz A. Barkan, MD FIAC, Johns Hopkins Medicine, Baltimore, MD and Eva M. Wojcik, MD, Loyola University Medical Center, Chicago, IL

The Paris System for Reporting Urinary Cytology (TPS) has been developed by members of the American Society of Cytopathology and the International Academy of Cytology to emphasize the goal of detecting High Grade Urothelial Carcinoma (HGUC) while minimizing the emphasis on Low Grade Urothelial Neoplasms(LGUN). Consequently, definition of the characteristics of the intermediate category of atypia aims at decreasing that category into a clinically meaningful one. Criteria for each category have been based on the best available clinical outcomes evidence. Rather than attempt to diagnose urothelial lesions in relationship to surgical pathology terms (WHO/ISUP Classification), TPScapitalizes on strength of cytomorphology for detecting HGUC because this diagnosis is both most meaningful for the patient and most realistic for the cytologist. The course will be constructed around the categories of TPS instructors will each address their particular category of interest: Adequacy, Olson; Negative for HGUC, Rosenthal; Atypical Urothelial Cells, VandenBussche; Suspicious for HGUC, Barkan; LGUN & HGUC, Wojcik. After this didactic presentation, there will be a question and answer period during which participants will be able to ask questions of the presenters. Finally, there will be an interactive section with images and the audience response system. This course is designed for cytopathologists, pathologists, cytotechnologists, or urologists at any level from trainee to experienced practitioner who deals with urinary cytology samples.

Upon conclusion of this presentation, participants should be able to:

  1. Elucidate the rationale for standardizing urinary cytology reporting
  2. Assign samples into the various diagnostic categories
  3. Recognize the morphologic characteristics to assign samples into the groups
  4. Appreciate clinical management implications of the diagnostic categories
  5. Relate the relative risk of HGUC according to the results of the cytologic interpretation for each diagnostic group.
