Is there such a thing as a negative Ki67? That is, are there women with breast cancer with a Ki 67 of 0. I thought it was a sliding scale, and that anyone with a Ki67 below 15 had a low proliferation rate, that from 15 to 25% was considered medium, and above 25%, high. One of the radiologists I went to see early on, told me he thought anything above 35% was high. I do remember reading somewhere that in the Milan Breast Center, they consider anything above 19% high. But it's so long ago. Can anyone answer about the "negative" Ki67. Thanks.
