Radiation therapy for incompletely resected XXXX .

@entity1 @entity1653 @entity5
Twelve @entity1 with incompletely resected @entity1653 were treated with postoperative radiation therapy. Nine of these @entity1 had previously undergone incomplete surgical resection, and three had suffered one or more postoperative recurrences. The median dose of irradiation was 5490 rads in 6 weeks (range 4800 to 6080 rads). All @entity1 were followed with serial neurological examinations and computerized tomography (CT) scans. Median follow-up period was 54 1/2 months (range 20 to 120 months); 10 of the 12 @entity1 were followed for longer than 42 months posttreatment. Nine @entity1 had no clinical evidence of recurrent disease after radiation therapy, and CT scans confirmed lack of progression or a gradual decrease in @entity5 size. Three @entity1 had @entity5 recurrences; two of these lesions appeared at 70 and 112 months after irradiation as extracranial extensions beyond the margin of the irradiation field, and one has exhibited recurrence within the field at 48 months. Three @entity1 who were treated after prior recurrences have demonstrated prolonged progression-free intervals in comparison to the intervals between recurrences prior to irradiation. No significant complications attributable to treatment have been found in any of the @entity1 . These results are discussed in relation to previous reports of the incidence of @entity1653 after incomplete resection.
