To address these issues and facilitate discussion on how to improve navigation services for patients with cancer, the National Cancer Policy Forum of the National Academies of Sciences, Engineering, and Medicine held a workshop on November 13 and 14, 2017. At this workshop, a broad range of experts and stakeholders, including clinicians, navigators, researchers, and patients, explored which patients need navigation and who should serve as navigators, and the benefits of navigation and current gaps in the evidence base.
