Since its founding in 1990, the profession of oncology navigation has grown and evolved. Although core concepts serve as a unifying thread throughout the profession, there has not been formal agreement on standardization of definitions, scopes, and roles for the various types of navigators. This has created challenges for sustainability, including reimbursement for navigation services. Emerging from the Biden Cancer Initiative's patient navigation working group, the Professional Oncology Navigation Task Force was created to serve as the voice of professional oncology organizations with an ultimate goal of solidifying definitions, scopes, and roles of navigators across the care continuum. Task group members are committed to cross-disciplinary partnership (including nursing, social work, and nonclinically licensed navigation). As the Task Force worked to define, refine, and disseminate professional standards (with input from the navigation community), the work done by the National Navigation Roundtable was vital to our evolving understanding of the profession. This article outlines the importance of that partnership and highlights the relevant findings of each article in this supplement of Cancer to the standardization work.
