Integrated Management of Stroke Risk in Brain Cancer: Insights from the Tumoral Bleeding Classification System and CanStroke Protocol

Brain cancer-associated stroke represents a complex interplay of oncological and cerebrovascular factors, distinct from conventional stroke mechanisms. Tumor-induced hypercoagulability, inflammation, and vascular disruption converge to create a unique clinical challenge that demands precision in diagnosis and management. This review synthesizes current evidence on the pathophysiological mechanisms, diagnostic innovations, and therapeutic strategies for brain cancer-related stroke while introducing two transformative frameworks designed to improve patient outcomes. We propose the Tumoral Bleeding Classification System (TBCS), a novel phenotypic framework categorizing tumoral bleeding into intratumoral and peritumoral subtypes, with further subdivisions to guide clinical decision-making. By linking these classifications to diagnostic biomarkers, such as D-dimer, and advanced imaging techniques, such as magnetic resonance imaging, the TBCS may enhance risk stratification and therapeutic targeting. Building on these insights, the CanStroke protocol offers an integrated, multidisciplinary, evidence-based management strategy tailored for brain cancer patients at risk of stroke. This protocol bridges oncology, neurology, and vascular medicine to address key challenges, including early recognition of stroke risk, individualized treatment plans, and mitigation of complications. Central to this approach is the integration of molecular diagnostics and pharmacogenomic data to optimize treatment pathways, aligning with precision medicine principles. This article highlights the critical need for diagnostic-therapeutic frameworks in brain cancer-related stroke, underscoring the value of the TBCS and CanStroke protocol in transforming care. By linking diagnostic biomarkers, imaging techniques, and therapeutic strategies, these innovations pave the way for improved survival, reduced morbidity, and enhanced quality of life in this vulnerable population.
