The Oncotype DX Test and Some Controversy

Most in the medical field would agree: early detection of breast cancer saves lives.  But how do doctors really know which treatments will be best to prevent the return of your cancer?

The Oncotype DX is a diagnostic test that helps your oncologist determine which treatment plan will most effectively prevent your cancer from returning (recurrence) or help to control your disease.

In order to be considered for this test, patients must have a diagnosis of estrogen-receptor positive (ER+), or estrogen-fueled breast cancer, be Stage 1 or Stage 2 and have no lymph nodes with cancerous cells, information that isn’t available until your lump has been biopsied.

When I went through breast cancer in 2004, I wasn’t offered the Oncotype DX test, perhaps because I was PR+, not ER+. Or perhaps it wasn’t available then, I haven’t had any luck finding out when the testing first became available.

What is the Oncotype DX?

The Oncotype DX test examines samples of tissue from your tumor and rates it for a specific set of genes that can influence the likelihood of recurrence within 10 years after your original diagnosis.  The result of the test is reported as a number between 0 and 100, known as the Recurrence Score® result.

The Recurrence Score

All of these test results make it easier for your oncologist to provide you with a diagnosis, but the genetic information (along with all of the other diagnostics) gives a clearer picture of whether or not your particular tumor will respond to chemotherapy to prevent any recurrence.

Your recurrence score will be based on the genetic expression of 21 genes, 16 of which are cancer-related, and 5 of which are reference genes. The genes are grouped by function: proliferation, invasion, hormone receptors (estrogen and progesterone), and growth factors. Each person’s test results will be unique, but will fall into one of three categories – low risk, intermediate risk, and high risk.

Those who have a low risk of recurrence may not need any chemotherapy and may be able to take hormone therapy as follow-up treatment after surgery. Those in the intermediate to high-risk categories may need chemotherapy as well as hormone therapy to further reduce a risk of recurrence. There are many other factors such as age, tumor grade, hormone receptor status, etc. that will be considered by your oncologist before a treatment plan will be put together, but research has shown that results from the Oncotype DX test are a very strong predictor for recurrence.

The Controversial Part

Medicare and several private health insurance companies will help cover the cost of an Oncotype DX test. Check with your insurance provider to find out if you are covered for this test. The current list price for the Oncotype DX is $4175.00 and it’s done by one company, Genomic Health.

This upsets me (and a whole host of others, let me tell you!).  There is no way that test should be so expensive.  It’s like holding us hostage – pay up or you aren’t going to know exactly which therapies you should be given. It’s absolutely disgusting.  I invite your comments below.

  1. Hi, Marnie,
    I had the Oncotype DX test done and was not impressed by the findings. The data is based on studies done in 80’s and 90’s and the test went on the market in 2004 (I called the company to discuss my questions and concerns and asked this of them).

    1. Dear Carolyn,
      Thanks for your input. Good to know. Just out of curiosity, did you use the score you received to decide whether or not you would undergo chemotherapy? Or did you decide to disregard it?
      Warmest regards,
      Marnie

  2. I had the Oncotype DX testing done. The lab did call me to let me know what my part of the cost would be, and also told me that when I got the bill, to call them. They will ask the patient questions, and they will waive some/all of the cost based on income, and other things. My husband and I both work as health professionals, but I got as far as the question of whether I had college age children, and since I have 2 in college, my cost was totally waived. And yes, this test ruled out Chemo for me, which would have cost so much more- physically, mentally, side effects, and money. I am sure it costs more than it could/should, but if there is any question about treatments, I believe it is worth every penny. It was to me.

    1. Dear Beth,
      Thanks so much for your comment and for sharing some of your experience with the Oncotype DX test with my readers. Blessings to you.
      Warmest regards,
      Marnie

  3. I agree with Beth. I also had the Oncotype DX test done in February 2016 and Genomic Health called me before performing the test to make sure I was willing to assume whatever portion of the bill was not paid by my insurance, which was estimated to be around $600. Based on the results of my test, my oncologist agreed that I did not need chemotherapy nor would it have helped me. This news was well worth any price! As of June 2016, I still have not received a bill from Genomic Health as they are still in dispute with my insurance company. Whether my bill ends up being $600 or $300, I will gladly pay! It is worth every penny. It really makes you stop and wonder how many women undergo unnecessary, costly chemotherapy. Long live Oncotype DX!
