Research and/or clinical interests 

Dr. Marco Mielcarek’s research focuses on graft-vs.-host disease, or GVHD, a potentially life-threatening complication in which newly transplanted donor cells attack the patient’s body. Dr. Mielcarek and his research colleagues are testing in clinical trials how to prevent GVHD and how to treat it effectively without causing unwanted toxicity. He and his colleagues have shown that carefully timed infusions of high doses of cyclophosphamide, a common chemotherapy drug, can safely and effectively prevent GVHD after growth factor-mobilized blood stem cell transplantation. As Medical Director of the Adult Blood and Marrow Transplant Program at Fred Hutch, Dr. Mielcarek's focus is on constantly improving the high level of clinical care in the program, and on seamlessly integrating cutting-edge clinical research with the patients' care experience.
