A new paper published in Neuro-Oncology Advances introduces the first-ever Guiding Principles for Adult CNS Tumor Treatment Programs in the United States. This was a joint effort among several brain tumor patient advocacy organizations, including the Musella Foundation. These principles fill a critical gap by defining what specialized, comprehensive care for brain and CNS tumor patients should include, such as expert multidisciplinary teams, molecular testing, access to clinical trials, and supportive services. The full guidelines are now publicly available to help patients and caregivers make more informed treatment decisions.
