Magee Equation

For those of you that had the oncotype test, did you do the Magee Equation and how accurate was it to the oncotype

There's some recent discussion about that here: https://community.breastcancer.org/forum/108/topics/869920?page=2#post_5564247

Ok, thank you. I checked out the thread. It seems as it's fairly accurate, wouldn't you say? Someone else mentioned about a post where ki67 and oncotype being similar? I couldn't find that thread though.

I’m the lone dissenter, I think, in that my Magee equation score has never been close. My Oncotype the first time around was 42, and Magee always puts me between 23 and 25. Even when I “cheat” the formula and use numbers different than mine, I can only come close when I enter triple negative with a 60% Ki-67. I’m not saying the equation isn’t accurate, rather I sometimes question my original pathology numbers, when my recurrence (exact same spot) was TN.
