9/30/20 - Dr. Sarah Milgrom Announces NCI Study Contract

Dr. Sarah Milgrom was recently awarded a multi-institutional NCI contract for an upcoming study. Here is what she stated she and her colleagues will be exploring:

Subsequent malignant neoplasms are an important late effect of radiation therapy in survivors of childhood cancers.  To date, no study has directly compared the risk of subsequent cancers in children treated with proton versus photon therapy.  The Radiation Epidemiology Branch (REB) at the National Cancer Institute (NCI) will obtain data regarding a large cohort of pediatric patients treated with photon and proton therapy in order to quantify the subsequent cancer risk.  We were awarded a contract to provide data regarding children treated with photon therapy at the University of Colorado.  These data will be used to quantify second cancer risk and to evaluate the risks and benefits of proton versus photon therapy for children with cancer.  Large-scale, collaborative efforts are urgently required to address these questions, and we are honored to contribute to this important work.
