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.
