Ki 67's Test

Hi Kathy. My surgeon asked for the Ki67 to be done from my initial core biopsy specimen. This then decided the order of my treatment. It was 35%, so I had chemo 1st, then surgery. The Ki67 on the surgical specimen was down to 5-10%. 

It was a good thing that it had reduced. Had they done it on any earlier pathology, for comparison?

Take care, Lyn

It was ordered for me after my initial biopsy showed there would be a need for it i.e. they did the Ki67 test on the tissue they extracted from my lumpectomy. This meant I had to wait 2 weeks before my final pathology results before they could determine what treatment I would get i.e. chemo. The reason for the delay is that they have to freeze the tissue sample which takes a few days. I have to admit the waiting really did my head in. Hope you get your results soon.

Thanks Nadine, mine was not done in initial path tests, this is now delaying my treatment options / decision and I am quite annoyed that a test that can provide you with this information is not an automatic request from Dr's / Surgeons ??

Hi. I had this test when my initial core needle biopsy showed I had HER2 positive breast cancer. My Ki67 was 70% which indicated that my cancer was super aggressive (anything over 20% is considered a fast growing cancer) making it a grade 3 cancer.
