In clinical practice, stroke physicians and cancer physicians increasingly work closely together. However, many unresolved issues remain, and clinicians often struggle with how to manage their patients. At the 2020 Annual Meeting of the Japan Stroke Society, the term “Stroke Oncology” was proposed to describe the relationship between the fields of stroke and oncology. Stroke Oncology refers not only to clinical research―such as discussions on the pathophysiology and treatment strategies of patients with both cancer and stroke―but also to the development of a multidisciplinary consensus covering a wide range of issues, including the establishment of care systems and treatment after the coexistence of both diseases. Currently, “Project Team on Stroke Oncology” has been established within the Japan Stroke Society, and a “Stroke Oncology Working Group” has been created within the Japanese Association of Supportive Care in Cancer, and collaborative activities have begun.
