Gregory Armstrong

Gregory Armstrong is a principal investigator of the Childhood Cancer Survivor Study (CCSS) at St. Jude, the largest and most comprehensive cohort study of long-term outcomes in childhood cancer survivors. His research documenting the cumulative burden of chronic health conditions and late mortality across treatment eras has demonstrated both the scope of late effects and the progress made through treatment modifications. His comparative analyses showing declining late mortality rates in more recently treated survivors have validated risk-reduction strategies.
