Largest Genomic Study in DCIS Shows Genomic Health's Oncotype
DX Predicts Local Recurrence, Helps Personalise Treatment of Stage
0 Breast Cancer
TORONTO, Aug. 20, 2015 /CNW/ - Genomic Health, Inc.
(Nasdaq: GHDX) today announced that Breast Cancer Research and
Treatment published results from a second large clinical
validation study of Oncotype DX® in patients with stage 0 breast
cancer, also known as DCIS (Ductal Carcinoma In Situ). The
population-based study, conducted by the Ontario DCIS Study Group,
reconfirmed that the Oncotype DX DCIS Score™ is a strong predictor
of local recurrence (p < 0.001), which could be either invasive
breast cancer or DCIS.
"Our study analyzed the impact of the DCIS Score as an
independent predictor of local recurrence in a population cohort of
individuals with pure DCIS treated by breast-conserving surgery
with clear margins," said lead investigator Eileen Rakovitch, M.D.,
FRCP(C), M.Sc., Sunnybrook Research Institute, and the Institute
for Clinical Evaluative Sciences, Toronto.
In Canada, it is estimated that
DCIS represents up to 25 percent of all breast cancers. Based
on a population-based cohort of 828 DCIS tumor samples collected
between 1994 and 2003 in Ontario,
the primary analysis focused on 571 patients who were treated with
breast-conserving surgery alone and had clear margins. The newly
published results of the study identified that the majority of
studied DCIS patients (62 percent) were low risk based on the tumor
biology revealed by the Oncotype DX DCIS Score. The remaining cases
had an intermediate-risk or high-risk score, and these patients
experienced a higher risk of local recurrence.
"We see a genomic test like Oncotype DX as an exciting advance
in precision medicine and customization of healthcare, which
is particularly important to the young women we serve who
are diagnosed with DCIS and face decisions about treatments that
can impact fertility and cause long-term side-effects," said
MJ DeCoteau, executive director at Rethink Breast
Cancer. "While the majority of DCIS is not life threatening,
it is important for patients to rely on a scientifically validated
tool to get precise biological information about their tumor to add
confidence in one's treatment choice."
About Oncotype DX®
The Oncotype DX® portfolio
of breast, colon and prostate cancer tests applies advanced genomic
science to reveal the unique biology of a tumor in order to
optimize cancer treatment decisions. The company's flagship
product, the Oncotype DX breast cancer test, has been shown to
predict the likelihood of chemotherapy benefit as well as
recurrence in invasive breast cancer. Additionally, the
test predicts the likelihood of recurrence in a pre-invasive form
of breast cancer called DCIS. With half a million
patients tested in more than 90 countries, the Oncotype DX tests
have redefined personalized medicine by making genomics a critical
part of cancer diagnosis and treatment. To learn more about
