The right way to deliver palliative radiation therapy for pain management
Posted Dec 17 2010 12:00am
It has come to our attention that the American Society for Radiation Oncology (ASTRO) has developed new guidance on the use of palliative external beam radiation therapy (EBRT) for the management of pain associated with metastasis of cancer to bone a relatively common problem in late stage, metastatic prostate cancer.
The fundamental issue was whether palliative radiation therapy to relieve pain cause by boney metastases can or should be given in a single dose or in fractionated doses. The task force has clearly come down on the side of single dose radiation for palliative care. To quote Dr. Lutz, the chairman of the task force:
… prospective randomized trials demonstrate that single-fraction EBRT provides equivalent pain control with similar or fewer side effects. If pain recurs, a single 8-Gy fraction can be safely and effectively repeated, according to the guideline. An added advantage of single-fraction treatment is its increased efficiency.

The task force did note that stereotactic body radiotherapy (SBRT) holds “theoretical” promise as a treatment for new or recurrent spine lesions, but recommended that its use be limited to highly selected patients at centers familiar with the dosing and risks of SBRT and, preferably, on a prospective trial.
