Lumpectomy, radiation, tamoxifen effective

WINSTON-SALEM, N.C., Jan. 22 (UPI) -- Radiation after a lumpectomy and five years of the drug tamoxifen cut the risk of cancer recurrence and new tumors in older women, says a U.S. study.

"While these treatments are standard care for younger patients, it is has been shown that older women are less likely to receive them," said lead author Ann M. Geiger of Wake Forest University School of Medicine and formerly of Kaiser Permanente Southern California. "Our results provide strong evidence of the importance of providing high quality care to all patients, regardless of age."

Geiger said there is a pressing need for information about the effectiveness of breast-cancer treatments in women over age 65 because this is an expanding segment of the U.S. population. Women in this age group are at the highest risk for breast cancer and make up half of those diagnosed but only recently have been included in treatment trials.

"Based on our findings, we recommend that mastectomy, or lumpectomy with radiation therapy, along with adequate duration of hormone therapy for women with hormone-responsive tumors, be considered standard therapy in women of all ages and health conditions, except for those with very limited life expectancies," said Geiger.

The findings are published online in Cancer and they are scheduled to be published in the March 1 print issue of the journal.
