Dr. Hur’s research group’s interests lie in outcomes research, specifically technology assessment with a focus on decision analysis and disease modeling, and the application of these methodologies to the management of cancers and pre-malignant states (e.g. dysplasia) in the gastrointestinal tract. This management includes the identification of clinical predictors, diagnostic algorithms, and the optimization of treatment. Some of our specific projects include a disease model of Barrett’s Esophagus and Esophageal Cancer, an analysis of the impact of the implementation of Virtual Colonoscopies for colorectal cancer (CRC) screening and the possible role for chemoprevention in cancer care. We are affiliated with the MGH Institute for Technology Assessment (ITA). The mission of the ITA is to conduct health outcomes research to guide the development, evaluation and utilization of medical technologies that improve the quality and cost-effectiveness of medical care.http://www.mgh-ita.org/
Additionally, we are a part of the National Cancer Institute’s (NCI) Cancer Intervention and Surveillance Modeling Network (CISNET), a consortium of NCI-sponsored investigators that use statistical modeling to improve our understanding of cancer control interventions in prevention, screening, and treatment and their effects on population trends in incidence and mortality. These models can be used to guide public health research and priorities. The MGH serves as the coordinating center for the esophageal cancer group’s collaborative research efforts.

Disease Model of Barrett's Esophagus and Esophageal Adenocarcinoma
Barrett’s esophagus- the construction and continued refinement of this disease model has allowed analyses that have attempted to determine the optimal management strategy for those patients with this pre-malignant condition which is a precursor to esophageal cancer. Specific analyses have addressed the cost-effectiveness of endoscopic surveillance, ablative therapies, as well aspirin for chemoprevention. Future areas of research will focus on the collaborative and multiscale modeling efforts with other groups through NCI’s CISNET.
Cost-Effectiveness of cancer chemoprevention (e.g. aspirin and/or selective COX-2 inhibitorsophagus
The use of non-steroidal anti-inflammatory drugs (NSAIDs) including aspirin and selective COX-2 Inhibitors for cancer chemoprevention is currently an area of much research. Using our disease model of Barrett's esophagus we have evaluated the cost-effectiveness of aspirin chemoprevention in this population. We have also modeled aspirin versus selective COX-2 Inhibitors in colon cancer chemoprevention.
Technology Assessment of "Virtual Colonoscopy
Virtual Colonoscopies for CRC screening- a mathematical model was constructed to determine the consequences if virtual colonoscopies were implemented for CRC screening. Future research in this area will focus on costs from various perspectives related to virtual colonoscopies and patient preferences for CRC screening.
