Breast Cancer Monitoring tests - Oncotype dx, Mammaprint, etc..

Posted by Laurie @roch, Jan 1 5:19am

In recent posts, there are references to some tests that were never offered to me when I was first diagnosed four years ago.

While researching, found great site that list all the different screening, diagnosis, and monitoring test used to diagnosis and determine treatment plans for breast cancer.

According to my oncologist, not all tests are needed in all situations, but definitely worth asking your provider about.

The Oncotype Dx was offered to me at diagnosis. Five years later I sought out the Breast Cancer Index and Prosigna Assay myself, to help with the decision on doing more years on an aromatase inhibitor. My doctors had never heard of these tests. I also paid nothing after applying for financial aid. We have to take care of ourselves.

Thank you for this information.

My oncologist ordered a MammaPrint when I was first diagnosed and had my biopsy. I didn’t know about all the tests then. The results of my MammaPrint indicated that I was low risk for reoccurrence. It indicated that there was a less than 1% chance of chemo being beneficial. I liked that the results helped dictate my treatment plan. One thing that has confused me is that my KI-67 was 49% on my pathology report but my MammaPrint showed low risk. Has anyone had scores like this?

I was grade 3, lymphovascular invasion and highish KI-67 at 20%. Oncotype people told me that KI67% is only one part of their evaluation of proliferation factors (I can't remember but there were 5-7). Doctors don't find Ki-67 that reliable. I have wondered if the healing from my biopsy threw it off. You can call MammaPrint and I am sure they will reassure you.

My Oncotype Dx was 22 – showing that chemo would not improve my odds of reoccurrence, So I skipped chemo & just had the lumpectomy and radiation. I was not told about KI67.

I had the Mammaprint test. It said less than 1-5% chance of returning in 10 yrs, no chemo needed and a Ki of 34%. I had metastatic to the bones in 1.5 years. I am not a believer in that test. Money wasted imo.
