Etan Orgel, MD
Assistant Professor of Clinical Pediatrics
CHL 4650 W Sunset Blvd, Off Campus Los Angeles
+1 323 361 2121


Dr. Orgel is currently an attending physician on the Medical Supportive Care/Survivorship and Supportive Care Program and the Leukemia and Lymphoma Team within the Division of pediatric Hematology, Oncology, and Blood & Marrow Transplantation at the Children's Hospital Los Angeles (Los Angeles, CA). Dr. Orgel's clinical specialty focuses on higher risk and rare malignant hematology, and specifically, the rare phenomenon of Mixed-Phenotype Acute Leukemia (MPAL). He possesses an academic appointment as an Assistant Professor of Clinical Pediatrics in the Keck School of Medicine of the University of Southern California (USC) following strong training in general pediatrics from Children's National Medical Center (Washington, DC) and a pediatric hematology/oncology fellowship at CHLA. This was complemented with didactic clinical trial training via completing a Masters of Science in Clinical and Biomedical Investigations from the Department of Preventive Medicine at USC.

Dr. Orgel's primary research interest lies in the field of medical supportive care or "cancer control" (reducing acute and late treatment-related toxicities). His specific focus utilizes a translational research approach to target specific toxic effects to widen therapeutic windows for common chemotherapies and/or improve the quality of life of children with cancer. Currently, Dr. Orgel's active research encompasses studying new agents and novel strategies to reduce hearing loss from chemotherapy (cisplatin), to target obesity in pediatric ALL to improve survival, quality of life, and bone health, and to evaluate resistance to asparaginase (a highly-effective chemotherapy agent) in children with relapsed ALL.
