I am 10% Pr+ and er and her2-. Wondering if tamoxifin would benefit me at all? Am I still considered triple negative?

    By my hospital's standards, you are not triple negative. I am less than 5% ER+ and have done very well on anti-hormonals.

    I am er- and 40% PR+.  I am doing antihormonals. Oncologist does not think there would be a huge benefit, but because I tolerate it well and it is not expensive, I am willing to keep going for 10 years.

    Hi - I am looking for others like me.  My core needle biopsy and post surgery path reports said I was er+, Pr+, HER2-.  Oncotype just came back ER-.  I understand this is very rare and I am frightened by the implications.  Any information you can provide is very much appreciated.

    I got the scoop from the one million Onc's I spoke with.  Genomics measures ER differently from other pathology labs.  Although this dramatic of a shift is very rare, I am not to worry about being helped by Tamoxifin.  The studies of Tamoxifin effectiveness used the same methods of measurement as used in my first pathology reports.

    hi Susan

    I'm in MA and was treated at MGH as if I was triple negative. I got 2nd opinion from Dana Farber which also said the same thing. When I was first diagnosed at newton Wellesley hospital the oncology said I was tnbc even though I had low positive PR at 15%. I'm getting radiation in 2 weeks for 6 weeks. When I finished I will be prescribed with tamoxifen. I wonder which major hospital did you go to and what were you prescribed for hormonal therapy? Thank you
