Biliary Cancer

Pedram Argani, M.D.

Primary Appointment in Pathology; Secondary Appointment in Oncology

My research interests span several broad areas of surgical pathology. First, as the Director of the Breast Pathology Program, I am currently involved in studies applying knowledge gained from global genetic analysis of breast carcinoma (such as SAGE and Microarray analysis) to well-defined histopathologic precursor lesions. Many of the new tumor suppressor genes identified have proven to be inactivated by methylation. We hope to be able to use these new markers to improve early detection and treatment of breast cancer.

Second, I am also interested in the molecular pathogenesis of biliary tract carcinomas, which are rare but highly lethal. Again, in this area we apply global genetic analysis to identify novel markers of disease which are of value in diagnosis, and potentially in imaging and therapy. Finally, I am active in the field of pediatric renal neoplasia where we have been able to define rare but morphologically and molecularly distinctive neoplasms.
