title: Ineffectiveness of chemotherapy in patients with metastatic ependymoma of the cauda equina.
abstract: Six cases of intraspinal ependymoma metastasizing outside the central nervous system have been reported. This report documents a seventh case. This patient received multiple courses of combination and single-agent chemotherapy without evidence of tumor regression. All seven patients had four things in common: early onset of disease, numerous operations, massive local recurrence at the time distant metastases were noted, and a long time period from diagnosis to death.
