Radiation Cuts Risk of Breast Cancer Recurrence by Two-Thirds
Many of the women studied who were given radiation would probably receive
chemotherapy and tamoxifen, a drug used to treat and prevent recurrence of
breast cancer, if they were diagnosed today, John M. Kurtz, MD, says in an
editorial accompanying the study. Kurtz, of University Hospital in Geneva,
Switzerland, says newer studies -- specifically, two large Danish trials --
show that modern radiation techniques can protect against the recurrence of
breast cancer and against death from breast cancer, while also reducing the
risk of death caused by damage to the heart and blood vessels.
Collins says that while the newer studies show promise, researchers will
need to follow the women's progress for another five to 10 years before they
can be certain that the newer radiation methods reduce the risks to the heart
and surrounding structures. More important, he says, is the need to consider
the overall benefit to the patient.
The good news is that this study proves that radiation works, says Lawrence
Solin, MD, an expert who commented on the findings for WebMD.
"This is an important lesson ... that local therapy can cure patients,
but it has to be done right, and today we think we have better techniques to do
that," says Solin, a professor of radiation oncology at the University of
Pennsylvania School of Medicine in Philadelphia. "The message for patients
is that they need to be certain they're being treated in a center with
high-quality technical radiotherapy."
- Women who receive radiation therapy for early-stage breast cancer following
surgery have a lower rate of cancer recurrence, according to a new study.
- Radiation treatment was associated with a slightly lower overall survival
rate, but researchers believe this is because the data is from the 1960s to
- Today, radiation techniques are better, as medical professionals can avoid
exposing the heart and surrounding structures to radiation beams.
