Malignant spinal cord compression(MSCC)is defined as a compression of the spinal cord or cauda equina with neuropathy caused by tumor spreading to the vertebral body. The common symptoms of MSCC are back pain, neck pain, muscle weakness, sensory reduction, bladder and rectal disturbance. The risk of MSCC is relatively high in patients with lung cancer, breast cancer, and prostate cancer. MSCC is one of the oncologic emergencies that requires prompt diagnosis and treatment to preserve and improve neurological function. Evaluation by magnetic resonance imaging(MRI)and computed tomography( CT)are useful for the diagnosis. The prognosis of these patients is often poor at the time of diagnosis of MSCC, thus it is important for deciding the treatment strategy to consider the prognosis and background of the patient in addition to the objective findings including the degree of MSCC and spinal instability. Treatment options consist of medical, surgical, and radiation therapy. We need a multidisciplinary approach because the pathology of MSCC involves multiple departments, such as medical oncology, orthopedics, and radiology. Supportive care including rehabilitation and preventing skeletal related events are also important. The cancer board, in which each physician and multidisciplinary health care professionals regularly have a discussion and review the cases, is required.
