Caitlin Costello, MD, is a board-certified hematologist and medical oncologist who specializes in treating a variety of blood cancers, including multiple myeloma, lymphoma, and leukemia. She is part of the joint UC San Diego Health / Sharp HealthCare Blood and Marrow Transplantation (BMT) Program, which provides patients with the unique opportunity to receive care from the same physician throughout all phases of blood cancer treatment.

Dr. Costello offers chimeric antigen receptor (CAR) T-cell therapy to adults with relapsed or refractory B-cell lymphoma, a type of non-Hodgkin lymphoma.

Her primary clinical interests include treating plasma cell disorders such as multiple myeloma, Waldenstrom's macroglobulinemia and systemic amyloidosis. Her research focuses on refining the management and treatment of these diseases. She is committed to conducting clinical trials for multiple myeloma with novel agents and regimens, with a goal to broaden therapeutic options and knowledge of this disease. She also has a special interest in precision medicine and developing treatment strategies that are most specific to the genetic and molecular details of an individual's disease.
