My husband had Taxol and Carboplatin as well as radiation but not for the same treatment cycle. He was given Taxol and Carboplatin after the clinical trial he was in failed to worked. He had six cycles of the chemo. The side effects were not terrible. John suffered diarrhea but that seemed to be something he would get everytime he got chemo. He had a day or two of nausea and fatigue then he would slowly get better. The MO called Taxol and Carboplatin "bread and butter" drugs. So I assume they are frequently given. Like Cisplatin, Carbo is also platinum based.
