Dr. Etan Orgel is an attending physician within the Children’s Center for Cancer and Blood Diseases. Dr. Orgel’s clinical specialty centers on treating children with acute leukemias and specifically those with higher risk and/or rare malignant hematology. This includes a focus on improving clinical outcomes for a certain rare type of acute leukemia named mixed phenotype acute leukemia (MPAL); while MPAL represents <2% of all acute leukemias, children with this form typically have a poor outcome.

Dr. Orgel’s research interest in medical supportive care (cancer control) overlaps his clinical interests with the overarching goal to improve the comprehensive care of children being treated for cancer. He leads medical supportive care efforts within the Center aimed at reducing treatment-related toxicities to optimize the use of currently available chemotherapy agent and to formulate best practice initiatives to help guide families and practitioners with “every day” concerns during therapy. As part of these initiatives, Dr. Orgel conducts research focused on identifying specific needs among patient populations related to acute or long-term toxicities. Once identified, in a true “bedside-to bench-and-back” approach, translational research collaborations with laboratory partners form the basis to develop early phase clinical trials to test new preventive strategies and/or novel investigational agents to mitigate the specific toxicity, allow for delivery of planned doses of chemotherapy, and limit the long-term impact of therapy on survivors of childhood cancer.

Dr. Orgel is active nationally within the Children’s Oncology Group Cancer Control and Supportive Care committee and Head Start consortium, has been an invited participant to national and international conferences on ototoxicity, and has been named in Southern California’s Rising Stars (top 2.5% of region) every year since becoming eligible in 2013.

  • Targeting obesity to improve therapy outcomes for childhood leukemia

  • Reducing treatment-related infectious morbidity and mortality
  • Optimizing the use of the chemotherapy drug asparaginase during therapy

Research Overview

Dr. Orgel’s primary research direction lies in hypothesis-driven medical supportive care clinical trials founded on strong translational research collaborations.  After completing a Master of Science in Clinical and Biomedical Investigations from the renowned Department of Preventive Medicine at the University of Southern California, he has led multiple epidemiological, retrospective, and prospective studies in cancer control and medical supportive care.  His publications and interests primarily focus on treatment-related toxicities that dramatically impact the quality of life of survivors, including permanent hearing loss, cardiac toxicity, and poor bone health from chemotherapy regimens, or severely affect outcomes during therapy, such as obesity’s impact on survival from leukemia and infectious morbidity and mortality during leukemia therapy.
