Rashmi Chugh

Rashmi Chugh, MD, Assistant Professor, Medical Oncology, Department of Internal Medicine, University of Michigan Health System

Dr. Chugh’s research focus is on the development of new therapies in the management of sarcoma and desmoid tumors. Sarcomas are cancers derived from connective tissue and span a wide range of histologic subtypes, clinical behaviors, and afflicted populations. They comprise less than 1% of all cancers and given their rarity and complexity of multi-disciplinary management, are best handled by a tertiary care sarcoma center. Our sarcoma multi-disciplinary treatment team is actively involved in research in all aspects of sarcoma care including systemic therapy, radiation therapy, and surgery. Unfortunately, systemic therapy for sarcomas is limited and only a minority of patients benefit from treatment. Dr. Chugh’s research involves conducting phase I clinical trials of novel therapies alone or in combination with standard cytotoxic therapy or targeted agents in this disease. The combinations are chosen based on rational laboratory or clinical evidence of potential benefit, and are taken to the bedside for further evaluation. Promising combinations will continue to be tested in her program in phase II trials.
