Trial Outcomes & Findings for Stereotactic Body Radiation Therapy (SBRT) for Tumors Near the Spinal Cord (NCT NCT00631670)

NCT ID: NCT00631670

Last Updated: 2012-02-03

Results Overview

Toxicities were graded using the RTOG-EORTC (Radiation Therapy Oncology Group-European Organization for Research and Treatment of Cancer) system and a descriptive system with which we coded any complication as mild, moderate, or severe based on our informal assessment of the complication's effect on overall quality of life. We assessed toxicity as "acute" meaning during treatment and "late" meaning several months after treatment ended.

25 treatments, given once a day, Monday through Friday for about five weeks; Dose: 70 Gy at 2.8 Gy/treatment
Local Control
24 tumors

SECONDARY outcome

Timeframe: 2 years

Population: 6 patients presented with tumor-related deficits before treatment.

Number of patients with a change in neurological function of those who presented with a neurologic deficit from tumor compression. The McCormack score was noted for each patient and the interval change was determined informally as no neurological deficit, better, worse, or unchanged as noted below.

SECONDARY outcome

Timeframe: 12 weeks

Population: Patients who reported pain at baseline

Number of patients who reported pain at baseline and reported experienced relief after treatment. Pain was defined on a 10 point scale with 0 being no pain and 10 being worst pain imaginable. Pain relief is defined as reporting a lower level of pain than that reported at baseline.
