BOSTON, May 21 (UPI) — Some older women with early-stage breast cancer could safely decline radiation therapy after a lumpectomy, researchers in Boston said.
A study at Massachusetts General Hospital showed older women with early-stage breast cancer who skipped radiation therapy after a lumpectomy were no more likely to die of cancer than women who got radiation.
“Avoiding radiation in this group is very feasible,” said Dr. Kevin Hughes, the study’s lead author, adding the use of radiation in such cases is a “value judgment” for patients.
The conclusions were based on a study of 636 women older than 70 who could be treated with the drug Tamoxifen. The women were divided into two groups, with one receiving Tamoxifen after a lumpectomy and the other group receiving radiation.
There was no significant difference in survival for women who received radiation, said the study, presented Thursday ahead of the American Society of Clinical Oncology’s yearly meeting in Chicago.
