The mission of Division of the Surgical Pathology is to provide the most accurate and timely pathology consultations serving the clinical trials of the NCI/NIH using the latest technology integrated in morphologic evaluation. Dr. Miettinen's research interests include pathology of soft tissue tumors and gastrointestinal stromal tumor. His group has delineated the prognostication system for GIST and clinicopathologic profile or GISTs of different sites. Current work includes prognostic, molecular, and biomarker analysis of sporadic and syndromic GISTs and evaluation of new diagnostic markers for soft tissue sarcomas and related tumors.
