The Breast Cancer News Update: June 15

Today's breast cancer news involves vitamin D, Epogen and a new HER2 test.

Exposure to solar vitamin D reduces breast cancer risk

A new study in the American Journal of Epidemiology examined the association between sunlight exposure, vitamin D production factors and breast cancer risk. A "solar vitamin D score" was "significantly associated with reduced breast cancer risk." According to a FoodConsumer.org article on the study,

Compared with women who had 6 hours per week spent outdoors, those who spent 21 hours or more per week during adolescence were 29 percent less likely to develop breast cancer. The risk reduction was 26 percent, 39 percent and 50 percent when the time was counted in the 20s to 30s, in the 40s to 50s, and in the 60s to 74 years, respectively.

Both the study abstract and the FoodConsumer.org story may be found on the Vitamin D page of our website.

Complications associated with Epogen for older metastatic breast cancer patients

Epogen, an erythropoietin-stimulating agent, is used to treat cancer-induced anemia. A new study in Cancer examined the complications associated with erythropoietin-stimulating agent use in metastatic breast cancer patients older than 65. Thromboembolic events, such as deep vein thrombosis, blood clots and stroke were "common" among this group of patients. "Therefore, caution is recommended when using these agents."

New HER2 test, the Inform Dual ISH, receives FDA approval

This week, the FDA granted approval to a new HER2 test, the Inform Dual ISH test. The test is similar to the fluorescense in situ hybrid (FISH) test, but the slides can be read using a standard light microscope. Both the FDA news release and a US News and World Report story can be found on the Inform Dual ISH page of our website.
