Spinal canal metastatic tumor

Spinal canal metastasis compression of the spinal cord is more common, because most patients once received a spinal canal metastasis usually receive pure radiotherapy or surgery plus radiation therapy, or give up treatment. Therefore, it is also difficult to determine the exact source of metastases. The primary lesions of spinal canal metastases are sometimes difficult to determine. The metastasis pathway of cancer cells is similar to brain metastases, mainly through the arterial, venous, lymphatic system, and subarachnoid cerebrospinal fluid. Malignant tumors throughout the body can be transferred to the spinal canal. Lung cancer, liver cancer, breast cancer, thyroid cancer, gastrointestinal cancer, and prostate cancer can all be transferred to the spinal canal via the arteriovenous system. Lymphatic tumors such as lymphosarcoma can directly invade hard spines through the intervertebral foramen through lymph nodes Extramembranes, damage to the vertebrae and compression of the spinal cord, 2% to 5% of lymphoid tumors invade the epidural of the spinal canal, damage to the vertebrae and compression of the spinal cord, acute leukemia, especially acute lymphocytic leukemia can infiltrate the spinal canal. Membrane or nerve root and the spinal cord blood vessel wall can cause spinal cord compression ischemia or bleeding, resulting in spinal cord dysfunction.
