Ependymomas of the spinal cord.
Many patients with spinal cord ependymomas (SCE) undoubtedly benefit from post-operative radiation therapy; however, because of the wide variability in the total doses given, the optimal post-operative dose for SCE remains unclear. Several recent papers recommend total doses of 4000 rad to 5000 rad in 4 1/2 to 6 weeks. Unfortunately, only a small number of patients reported in the literature have been consistently treated to these high dose recommendations. Nine consecutive adult patients with SCE have been treated in a consistent way at Yale-New Haven Hospital with total doses of approximately 4500 rad to 5000 rad at 180 rad to 200 rad per day. The acute and chronic morbidity from such treatment has been minimal and no patient has had a local recurrence at 8 months to 8 years following treatment.
