In Brief
Ovary Removal Linked to Higher Death RatesPremenopausal women who have had their ovaries removed but do not receive adequate hormone replacement therapy have a higher risk of death from several causes, a study shows.
Walter Rocca, M.D., of the Mayo Clinic in Rochester, Minn., and colleagues monitored 1,293 premenopausal women who had one ovary removed, 1,093 premenopausal women who both ovaries removed, and 2,390 controls. The authors found that premenopausal women who had their ovaries removed and did not receive adequate hormone therapy had an increased risk of death from hormone-related cancers and brain or cardiovascular disease. The risk became evident only 10 or more years after the procedure.
The study was published in the October issue of Lancet Oncology.
Study Identifies Genes Associated With Prostate Cancer Risk in African American Men
Several regions of the human genome probably contain genes that, when altered, are linked to prostate cancer risk in African Americans, according to a study from 12 research centers.
Researchers in the African American Hereditary Prostate Cancer study network examined 418 African American men with prostate cancer and their 77 extended families. The researchers used genetic markers to identify areas of the human genome that might contain genes linked to prostate cancer.
The study was published in The Prostate.
NIAID Awards $4 Million For Development of Antiradiation Treatments
The National Institute of Allergy and Infectious Disease awarded five grants totaling $4 million to researchers developing products that eliminate radioactive materials from the body after radiological or nuclear exposure.
If a nuclear explosion occurred, humans could inhale, ingest, or absorb radioactive atoms, which would cause health problems, including cancer. The grant recipients will design drugs that target radioactive atoms and eliminate them from the body.
