    I'd like to know who out there knows about this test and has had it done.

    I understand it is a test to assess risk of mestastis in early stage BC. My question is it normal to run this teast after active treatment has ended? The only reason I know it was run is because of insurance claim paperwork. I was diagnosed in April 2011, had bilateral mastectomy in May 2011, 4 rounds of TC July - September 2011. Now on Tamoxifen as my cancer was ER and PR positive. I intend to ask my oncologist about this when I see him next in April. In the meantime I am curious about what the test will reveal and what could change in my treatment plan if it turns out I have high risk of mestastis??

      It is essentially the same thing as an oncotype test that analysis genomes to develop a score that quantifies the risk of metastasis and potential benefit of chemotherapy. I had advance stage (3B) breast cancer and therefore did not meant the qualifications of the test. When was the test run? I would assume it was some time before your chemo, otherwise, there would have been no point, unless it was just being done for a clinical trial registry, in which case, I would be surprised if you insurance company would be willing to pay for it.

      According to the insurance paperwork (and it was covered) the test was run Nov 2012, over a year after my last chemo treatment.

      That indeed is very strange. Did you have any other followup routine lab tests that month? There is no way they could have gotten the tissue sample to run the test without your knowledge. I'm thinking there must be a clerical error here somewhere.

      I think it was ordered between oncologist visits (labs are done at each one). My understanding (from googling it) is that it could be done from the frozen cells taken at the original biopsy from time of mastectomy.

      RMR our facility at this time only uses the OncoDx testing and this is always done prior to chemotherapy being performed. I suspect that from facility to facility you may find differences. Unfortunately as none of my MD's that I work with currently order this particular test I am not aware of the exact way it is used or timing for it's use. I recommend a great site for reading more on the test. http://www.breastcancer.org/symptoms/testing/types/mammaprint. I would definitely discuss this with your oncologist in order to understand his/or her's reasoning for ordering the test and for the timing of when it was done. I hope this helps you some.

      Thanks everyone for the answers you have shared. Of course I am still confused. Just to clarify, I had oncotypec dx done when originally diagnosed and deciding on treatment plans. It was in the intermediate range and I chose to throw everything I can at my cancer do I had four rounds of TC. I am wondering if the mammaPrint is being used to determine the benefits of continuing with hormonal therapy (I am on Tamoxifen)?? I guess I will have to wait for my April oncologist appointment.
