Clinica E.T. EAST, located in Shinkawa, Chuo Ward, Tokyo, is a radiology-specialized clinic. The clinic focuses on endovascular therapy, offering unique treatment perspectives for patients with advanced or metastatic cancer who have not achieved sufficient results with standard treatments. Specifically, their approach involves organizing abnormally proliferating blood vessels around tumors to improve hypoxic conditions, and rather than attacking cancer cells with chemotherapy, they use lymphocyte antibodies to restore CD8 cell function and activate immune response. In addition to endovascular cancer therapy, the clinic also performs endovascular treatments for rheumatism and chronic pain, making it characteristic for addressing a wide range of refractory diseases. Clinic hours are 9 AM to 5 PM on weekdays, closed on weekends and year-end holidays. The clinic accepts credit cards and electronic payments, and has barrier-free facilities, creating an accessible environment for diverse patients. For patients who feel limited by existing treatment options, this medical institution offers the possibility of considering endovascular therapy as an alternative.
