Oncotype DX Results
The results of Oncotype DX® are provided as a Recurrence
Score®. The Recurrence Score is a number between 0 and 100 that corresponds to
a specific likelihood of breast cancer recurrence within 10 years of your
initial diagnosis.
-
If your Recurrence Score result is 17 or below, you are considered to have a
low risk for breast cancer recurrence. However, a low-risk score does not
necessarily mean that your breast cancer will never come back or recur.
-
If your Recurrence Score result is between 18-30, you are considered to have an
intermediate risk for breast cancer recurrence. This means there is a chance
that your breast cancer will come back or recur; however, your risk is neither
low nor high.
-
If your Recurrence Score result is 31 or above, you are considered to have a
high risk for breast cancer recurrence. However, a high-risk score does not
always mean that breast cancer will come back or recur.
Each score indicates a specific risk of recurrence. In other words, a score of
18 indicates a different likelihood of recurrence than a 28, even though they
are both in the intermediate-risk category.
In addition to predicting
your likelihood of breast cancer recurrence, the Oncotype DX
Recurrence Score assesses your likely benefit from
chemotherapy.1 If your
Recurrence Score result is low; you are likely to receive little if
any benefit from chemotherapy. If your Recurrence Score result is
high, you are likely to receive a significant benefit from
chemotherapy. This information, together with information about the
chance that your cancer will come back; can help you and your doctor
make a decision about the treatment that is best for your individual
case.
The Oncotype DX report also
includes measurements of the level of activity of gene expression
for estrogen (ER) and progesterone (PR) receptors which are part of
the Recurrence Score result. These two receptors are
routinely measured by pathologists using a different technique.The level of estrogen
receptor gene expression activity may help you and your doctor with
treatment planning.
