A three-level staging system has been developed and validated for primary and secondary brain tumors that is capable of prognosing survival.
Why this matters
Primary and secondary brain tumors are common and associated with significant morbidity and mortality.
Most tumor types have spatiotemporal staging systems that define the extent of anatomic tumor spread over time as it relates to histopathological de-differentiation and prognosis. However, there is no such staging system for brain tumors, introducing challenges for accurate prognosis and barriers to the development of personalized therapy.
Development and validation of a staging system for brain tumors will help to more accurately prognose and inform treatment decisions for patients with brain malignancy.
