Scientists at St. Jude Children’s Research Hospital are reporting the most comprehensive study to date describing the variations in drug response across different genetic subtypes of acute lymphoblastic leukemia (ALL). The findings provide a blueprint for precision medicine to further individualize
In a groundbreaking study, researchers at St. Jude Children’s Research Hospital have collected the most extensive data yet on how different genetic subtypes of acute lymphoblastic leukemia respond to various medications. This information offers a roadmap for customizing treatment for each individual patient, paving the way for truly personalized precision medicine.
“Compared to traditional cancer genomics research, our pharmacogenomics work starts with defining the drug response phenotype of each patient, after which we look into genomics to search for the biological basis for the inter-patient variability in leukemia drug sensitivity,” said corresponding author Jun J. Yang, Ph.D., St. Jude Department of Pharmacy and Pharmaceutical Science.
The findings add a functional understanding to previous studies that identified high-risk or favorable subtypes. For example, ETV6-RUNX1 ALL has a favorable prognosis while BCR-ABL1-like ALL has a poor prognosis. These pharmacogenomics findings provided insight into why individuals with those subtypes had certain types of prognoses.
