    I just read a report about the MammaPrint test, which is apparently more involved than the Oncotype DX test. The gist of the story is that it can identify patients who won't really benefit from chemotherapy(which my wife is scheduled to begin next week).

    Has anyone heard of it--or had it?

    It's so difficult to know which route is the correct one--chemo(two courses offered by our oncologist) or NO chemo. We were told that, based on my wife's Oncotest, her chances of recurrence are 26%. With chemo, it's 16%. Whlie a 10-percent difference is significant I'd have thought chemo would lower the chances into single digits.

    Swami7774 - I didn't have the Mammoprint, since my Oncotype score came back so high to begin with (42) that my MO didn't see a point in doing additional testing. It's important to remember that that 10% difference in recurrence rates assumes your wife will also be taking Tamoxifen for (at least) 5 years. That 10% difference is halved if your wife chooses not to take Tamoxifen or an AI (as some do), to about 21% recurrence (this is based on a conversation I had with my MO, as I chose to stop Tamoxifen after 8 months due to SEs, and had an Oncotype score almost the same as your wife's). Chemotherapy is one tool in the arsenal that helps reduce the risk of recurrence.
