Dr. Mary Flowers leads a team at Fred Hutch and its clinical-care partner, Seattle Cancer Care Alliance, that supports bone marrow and stem cell transplant survivors long after they finish initial treatment. She is a world-renowned expert in the study and treatment of chronic graft-vs-host disease, or cGVHD, a complication of transplantation in which the donated stem cells attack the recipient's healthy tissues. As director of the world-class post-transplant Adult Clinical Care Long-Term Follow-Up Program, known as the LTFU, Dr. Flowers and colleagues help transplant survivors and their primary care physicians manage post-treatment complications as patients recover and resume their lives. The LTFU also serves as a model for the training of transplant physicians, as does the Fred Hutch chronic GVHD training program, which attracts hematology/oncology fellows and visiting physicians from transplant programs across the U.S. and in more than 12 countries. In addition to her GVHD research, Dr. Flowers studies the effectiveness of using donated lymphocytes, a type of immune cell, to treat recurrent malignancies after transplantation with donated cells.
