Sorry to hear about your dx, Stephanie.
At a week and a half after your treatment, you are probably at your nadir -- the point where your counts are lowest. The time between treatments should allow your counts to recupe. This drop in the count is not 'cumulative' as long as the next treatment is not given before your CBC and diff is within safe levels to give the drugs. (That's why you have to have all the blood tests before your next treatment.) Treatment regimens are scheduled to accommodate this fluctuation in the levels due to the drugs, but sometimes we do have to postpone the next tx a few days -or a week- until the counts come back up.
Do you know what your AGC is? As long as our patients do not develop neutropenic fevers and their counts come back up in time for the next treatment, they generally will not need neupogen.
We rarely give procrit in conjunction with our chemo regimens.
An excellent website for both nurses and patients is
