Pathologists who evaluate specimens from the gastrointestinal tract occupy an expanding role in disease management teams. The widespread availability of endoscopy coupled with advances in tissue acquisition techniques have drastically increased the number and variety of gastrointestinal samples pathologists encounter in daily practice. As a result, pathologists are now required to provide comprehensive diagnostic information based on review of scant material. Classification of tumors is often completed based on interpretation of immunohistochemical stains coupled with molecular analyses to identify druggable targets or underlying germline conditions. Pathologists also direct the evaluation of patients with gastrointestinal complaints, particularly when patients have persistent symptoms or are immunosuppressed. Thus, they must be able to hone in on key features present in biopsy material in order to narrow the differential diagnosis and better direct patient care. This course is intended to address these needs in a succinct and pragmatic fashion.
Target Audience
Practicing academic and community pathologists, and pathologists-in-training
