I had weekly carboplatin during rads. It worked fine for me and still effective as it is platinum based. I have no personal reference to compare against the 3 week cycle and have zero interest in doing for the sake of comparing. lol

Only thing with some certainty is if you having ringing than that is a sign to get off the platinum stuff in a jiffy. good luck don
