As I have posted in the past, my Ca125 had risen to 3500 6 months ago, switched over to low dose taxol and the marker dropped to 13 within 3 months. been maintaining the taxol every other week, very very tolerable but my CA125 has systematically creeped up to 20 over the past 2 months. My doctor now is switching me over to Abraxane. I realize this is taxol but will it be more effective and will the side effects be greater, different or what. And why would Abraxane be more effective than taxol is now. Believe me I am thankful that my marker is still as low as it is. Once you are in the rarified air of 3500 being where I am now is pretty pretty good. I will be speaking to the doctor tommorrow to see what the dosage will be. never ever dull is it?
