yes it was something mentioned by the oncologist - I think not all oncologists look at it - its reasonably new for them to take these results into account. If the ki67 had not had a high reading I would not have had chemo - but the recurrence and spreading as my tumour was aggressive was too high a riske for me. I have my life on hold really til this chemo is over (aside from work) - can't wait til its finished. and I will be so happy I gave it everything even though its the "hard road". The nuelasta helped me - I felt soooo tired first round, still tired this round but not so much and did not suffer the mouth ulcer I had last round.
good luck whatever you decide.
