Oncotype vs Mammaprint

Has anyone gotten both tests and had a 'middle range' Oncotype and then also get a 'low risk' in their mammaprint?

I'm waiting for results right now on my Mammaprint and I am wondering what the likelihood is that I will end up with low risk.

Thanks, lovelies!

    That is exactly what I had. Got a 19 on Oncotype, then did Mammaprint and got low risk. Still did chemo.

    I got a DX 25 :/ Can you share with me why you decided to do chemo? I see that you had involved nodes, did that play a role?

    I had 17 and 19 on Oncotype for my bilateral breast cancer and then low risk for mammoprint, I still did chemo as well.

    Wow. I had an oncodx score of 34, high risk, and didn't do chemo. I am still ok 6 years out. I didn't want to risk my overall health on the 2 small spots that didn't seem to get outside the breast.

    One idc one ilc with er+ and pr- her2 equivocal. I felt if chemo worked more people won't get recurrences.

    I did not have nodes involved. I thought oncodx was only for her2 negative.

    Hi, My mammaprint showed high risk, but my oncologist said that he did not think I needed chemo because my tumor was small and I had no positive nodes. Has anyone else had a high risk result on their mammaprint and then been told that no chemo was needed? I thought the whole purpose of a mammaprint was to say yes or no to chemo.

    Can you elaborate on Mammaprint? My tumor was small with no spreading, but I still needed chemo because the oncotype score was 31. I am doing dose dense once every 2 weeks over two months, and then once a week x 12 weeks.

    Oncotype and Mammaprint are different tests in the sense of what they predict. For those who rely heavily on the results of either of these tests in making treatment decisions, I recommend you read the descriptions posted on BCO and also ask your MO to clarify what your results mean in your case. Here's the link the Genomic Tests Description
