When I complained of serious hearing changes after two cisplatin treatments, the older MO immediately switched me to carboplatin and taxol (goodbye hair). He said many years ago he had a patient who ended up deaf as a post, and that less than 1% of patients ran that risk. The carboplatin/taxol treatments I then received seemed to do that job as I am closing in on five years and had my hearing tested recently and was found to have no loss at all.
