ASCO: single radiation Tx enough for spinal pain in cancer mets
(HealthDay)—Just one dose of radiation works as well as a full week of treatment for metastatic spinal canal compression, according to a study presented at the annual meeting of the American Society of Clinical Oncology, held from June 2 to 6 in Chicago.
Peter Hoskin, M.D., of the Mount Vernon Cancer Centre in Middlesex, U.K., and colleagues assessed 688 patients with metastatic prostate, lung, breast, and gastrointestinal cancers.
The researchers found that a single radiation treatment was as effective as five radiation sessions. The patients were assessed by how well they could walk and move. Both short-course and longer-course radiation treatments helped patients stay mobile.
"Our findings establish single-dose radiotherapy as the standard of care for metastatic spinal canal compression, at least for patients with a short life expectancy. For patients, this means fewer hospital visits and more time with family," Hoskin said in a news release from the American Society of Clinical Oncology. "Longer radiation may be more effective for preventing regrowth of metastases in the spine than single-dose radiation. Therefore, a longer course of radiation may still be better for patients with a longer life expectancy, but we need more research to confirm this."
Several authors disclosed financial ties to the pharmaceutical industry.
