1. Describe the role of mismatch repair (MMR) testing in the setting of hereditary cancers, molecular classification of Gastrointestinal and Gynecologic cancers, a predictive marker for immune checkpoint therapy and diagnostic marker.
2. Breakdown the steps for analysis of MMR interpretation for GI and GYN tumours and examine cases with difficult MMR interpretation.
3. Develop a comprehensive quality assurance program for MMR testing.
4. Formulate interpretative comments for clinicians using clear nomenclature to assist in guiding management and trigger appropriate follow-up measures.
The session will utilize a combination of didactic lecture and case-based examples with incorporation of real-time audience participation by electronic polling. This will be completed by providing attendees case-based staining patterns for MMR IHC and asking in a multiple choice format their interpretation choice.
