Radiation therapy appears to substantially benefit
older patients with ductal carcinoma in situ (DCIS),
a noninvasive cancer of the breast's milk duct.
Benjamin D. Smith, M.D., of the Yale School of
Medicine in New Haven, Conn., and colleagues used
the National Cancer Institute's Surveillance,
Epidemiology, and End Results database to identify
3,409 women age 66 and over who had undergone
conservative surgery for DCIS. They examined whether
additional treatment with radiation therapy was
associated with lower risks for subsequent
mastectomy or invasive breast cancer.
The authors found that radiation therapy was
associated with lower risk of subsequent mastectomy
and invasive breast cancer in both low- and
high-risk patients. Radiation therapy was associated
with a 68% reduction in the relative risk for a
second breast cancer event.
