Oncotype is recommended for those with 1-3 nodes positive.

Ki67% is actually one of the proliferative factors included in the Oncotype but there are several. My ki67% was high but my Oncotype was low so I called Genomic Health to ask them. Also I had grade 3 and they told me 30% of grade 3's have low Oncotypes.

Many docs don't order the ki67% because it is considered unreliable. I still wonder if healing biopsy tissue threw mine off.
