The annual Society for Immunotherapy of Cancer (SITC) meeting held Nov. 1-5, in San Diego, CA., was an exciting time for experts in the field to gather and discuss their work in cancer immunotherapy. Researchers, physicians, clinicians and students from around the world presented their research via oral and poster abstract presentations, mingled and enjoyed camaraderie in the warm Southern California sun.
Researchers and oncologists from Earle A. Chiles Research Institute, a division of Providence Cancer Institute of Oregon, attended the conference, contributing to 21 abstracts selected for poster presentations and an oral presentation.
Additionally, Bernard Fox, Ph.D., gave opening and closing statements at the World Immunotherapy Council Young Investigator Symposium on opening day. Rachel Sanborn, M.D. served as a session co-chair in the Concurrent Session 107d: Oral Abstract Session; and Brian Piening Ph.D., and Rom Leidner, M.D., spoke at the sponsored symposia, presenting the study, “Using hyperplex immunofluorescence to characterize the immune response to iSABR in head and neck cancer.”
