Study found giving it before radiation raised death risk 20% in this group
TUESDAY, Sept. 23 (HealthDay News) -- Older men with early-stage prostate cancer who are given hormone therapy before radiation seed implant therapy face a 20 percent greater risk of dying than those who get radiation treatment alone, new research suggests.
Focusing on men over the age of 70, the study summed up the risks of death from any cause linked to androgen-deprivation therapy. Such treatment is sometimes given before radiation treatment to lower male hormone levels, shrink the prostate, and retard cancer growth. Brachytherapy itself involves the insertion of small radioactive seeds into the prostate to destroy cancer cells.
"We know that hormone therapy has a lot of side effects," noted study author Dr. Amy M. Dosoretz, a radiation oncology resident with the Harvard Radiation Oncology Program in Boston. "Depression, fatigue and anemia, among others. Yet it can be worth it, because it has a significant benefit for many patients. But for some patients, the risks may outweigh the benefits. And here, we found that in this particular group of patients -- early-stage prostate cancer patients over 70 -- there was an increased risk for mortality."
Dosoretz and her colleagues were expected to present their findings Tuesday at the American Society for Therapeutic Radiology and Oncology annual meeting, in Boston.
The team's risk assessment is based on a mortality analysis involving more than 1,700 early-stage, localized prostate cancer patients. The men were between the ages of 70 and 91, and received either hormone and brachytherapy treatments or brachytherapy alone between 1991 and 2005.
For those who received hormone therapy, treatment lasted three and a half months on average.
The authors found that undergoing such hormonal intervention was associated with an increased risk of dying from all causes. Being older
