Jason Hornick

Jason L. Hornick, MD, PhD is widely known for his major research on soft tissue sarcomas and gastrointestinal cancers. His focus in soft tissue sarcomas includes evaluating histologic and immunohistochemical parameters that predict clinical outcome, and identifying diagnostically useful immunophenotypic markers. He is currently studying gastrointestinal stromal tumors, leiomyosarcomas, histiocytic and dendritic cell sarcomas, and neural tumors of skin and soft tissue. Dr. Hornick’s focus in gastrointestinal cancer is the pathology of Barrett’s esophagus and associated dysplasia and adenocarcinoma, in particular with the goal of improving the prognostic value of endoscopic surveillance biopsies, and studying the clonal evolution of neoplasia in Barrett’s esophagus. In addition to esophageal adenocarcinoma, he also studies colorectal carcinoma and pancreatic carcinoma.

Dr. Hornick is Director of Surgical Pathology and Director of the Immunohistochemistry Laboratory at Brigham and Women’s Hospital, Associate Professor of Pathology at Harvard Medical School, and a Consultant in Pathology at Dana Farber Cancer Institute. Dr. Hornick’s clinical specialties include surgical pathology, soft tissue and bone pathology, hematopathology, gastrointestinal pathology, and molecular genetics. He has published research on over 50 topics in his areas of expertise and is a frequent contributor to medical journals. Dr. Hornick was awarded the Arthur Purdy Stout Society of Surgical Pathologists Annual Prize in 2012, in recognition of significant career achievements in surgical pathology under the age of 45 years. He is the author of Practical Soft Tissue Pathology, a volume in the Pattern Recognition series.
