Based on progress to date, Dr. De Oliveira was awarded a new grant in 2014 to fund an additional year of this Scholar award. New therapeutic approaches are needed for pediatric leukemia and lymphoma, because patients with refractory or relapsed disease still have a survival rate of less than 50% with current therapies. This research involves a novel cancer immunotherapy protocol, transferring a gene into the patient's own blood stem cells, giving rise to immune cells able to directly and specifically target a surface molecule that is present in more than 95% of leukemias and lymphomas. This project evaluates the cancer cell destruction by the modified immune cells, setting a basis for future clinical trials.
