I am just completing the 5th cycle of Sutent at 37.5 mgs. I, too, run very low on platelets; and, at the conclusion of cycle 2, required a transfusion for very low hgb. Since that time I have been on an iron supplement and am maintaining a good level of hgb. Platelets increase to low, but acceptable, levels during the hiatus period.
I am getting very good results on my lung mets and no mets showing up anywhere else. I am finding my side effects more tolerable.
My history includes left nephrectomy in September of 1996. Met disease, lungs, partial lung resection August of 2005. Right kidney tumor rfa March 2006. Sutent cycle 1, January, 2007.
Celebrated my 80th birthday with children and grandchildren July 2007.
Hang in there.
