Hi Donna, I am receiving the Carboplatin once every 4 weeks. I have only 2-3 days of nausea afterwards, then I do really well. The doctor has offered it every week or every two weeks using a lesser dose to avoid this nausea; however, I would rather go only once a month rather than 2-4 times per month. If there was any benefit for more frequent doses, I would do that in a minute! So far, it is keeping the tumor markers stable with minimal side effects. Good luck with your treatments!! Hope all goes well for you! Please keep me posted how this combination of meds works for you. Debbie
