Lori J. Pierce, M.D., was one of 30 cancer scientists elected to the American Association for Cancer Research class of Fellows of the AACR Academy. Pierce was elected for illuminating contributions to establishing radiotherapy in the multimodality treatment of breast cancer, including intensity-modulated radiotherapy for node-positive breast cancer and incorporation of radiosensitizing agents, which have collectively resulted in improved treatment outcomes for breast cancer patients, most notably those harboring BRCA1/2 gene mutations.
