The National
Institutes of Health's National Cancer Institute this
week launched a study seeking to better understand the
genetic links to breast cancer and how those genes
might be used to help determine the best course of
treatment, The Wall Street Journal reports. The
study, called "Trial Assigning Individualized Options
for Treatment," will include more than 10,000 U.S. and
Canadian women who've been diagnosed with
early-stage breast cancer. Each woman will undergo
genetic tests to examine the role of 21 key genes in
predicting breast cancer recurrence. The study
participants will be divided into treatment
groups--those receiving hormonal therapy, those
receiving chemotherapy, and those receiving a
combination of the two. The women will be followed for
up to 20 years. The researchers hope to determine
links between certain gene mutations and the most effective
treatments to prevent breast cancer recurrence based
on those mutations. (The Advocate)
