From 1980 to 1987, 162 consecutive children with soft tissue and osseous sarcoma were reviewed to determine the frequency and types of neurologic complications seen. Neurologic complications occurred in 43 of 162 (26.5%) patients. Children with poorly differentiated sarcomas and rhabdomyosarcoma were more likely to have neurologic complications, which occurred in 39% of patients at risk. The types of complications seen included: metastatic spinal cord compression (11%); symptomatic peripheral neuropathy (10%); intracranial metastatic disease (7.5%); seizures (6%); and acute and chronic methotrexate-related neurologic dysfunction (2.5%). Spinal cord compression frequently occurred early in disease whereas brain metastases was almost always a late finding. Symptomatic peripheral neuropathy occurred primarily in children with rhabdomyosarcoma and Ewing's sarcoma. The advent of increasingly successful therapies for children with sarcoma and the frequency of severe neurologic complications indicate that a heightened level of surveillance for neurologic compromise is required.

Transient or permanent paraplegia after the use of intrathecal (IT) methotrexate (MTX) or cytosine arabinoside (Ara-C) for treatment or prophylaxis of patients with meningeal leukemia is an unusual complication, with an incidence of less than 3% among such patients. Only 15 cases involving IT MTX have been documented and even fewer with IT Ara-C. Three patients were studied who developed permanent or ascending myelopathy from treatment of their leukemia or rhabdomyosarcoma with IT chemotherapy. The patients' ages ranged from 7 to 62 years. Two of the three patients had electromyographic examinations. These revealed a primary motor neuron degeneration or a polyradiculopathy, superimposed on a mild axonal peripheral neuropathy associated with vincristine therapy. This is consistent with other electromyographic studies. Two of the patients showed an elevation of the cerebral spinal fluid (CSF) protein before development of paraplegia; one also showed a rise in myelin basic protein associated with his myelopathy. Neuropathologic findings suggest demyelination as the primary process leading to myelopathy. Increasing evidence has shown that total CSF protein, or more specifically, the myelin basic protein, may be elevated before development of paraplegia. Routine serial testing of the CSF for total protein could be used as a screening test during therapy.
