About ZoAnn Dreyer

Dr. ZoAnn Dreyer is a Co-Director of the Long Term Survivor Program where she acts as Clinical Leader of the Long Term Survivor Clinic at Texas Children’s Cancer Center. Over 1,000 childhood cancer survivors are evaluated every one to two years for delayed effects of their prior cancer therapy. Survivors are patients who are more than five years from their diagnosis and off therapy at least two years. There is no upper age limit for survivors followed in the clinic. Survivors are now invited to become participants in a novel program, the Passport for Care® Application.

Dr. ZoAnn Dreyer’s clinical interests include acute lymphoid leukemia in infants younger than one year old. She was the principal investigator for an innovative, nationwide treatment protocol for these infants that have resulted in dramatically improved survival rates. She is currently principal investigator of a new pilot study using intensified asparaginase in patients with high risk ALL.

Dr. Dreyer earned her bachelor’s degree and medical degree from the University of California, Davis, Calif. She served her internship, residency and postdoctoral fellowship at Baylor College of Medicine, one of the nation’s leading medical schools. She is a member of the Leukemia Program and the Long Term Survivor Program.
