@dutchw My husband had four intiial chemo treatments (Carboplatin, Alimpta, Keytruda) with horrible side effects. The maintenance was Alimpta/Keytruda. The first treatments worked and the maintenance failed. Chemo, radiation, and immuntherapy can all cause heart effects. Our doctors are leaning toward the immunotherapy having the rare side effects we're seeing now. Also, the Keytruda./Alimpta is not working. After we stopped the initial full treatment rounds, the cancer returned and spread. My husband has a cancer that can't quite identify (cancer of unknown primary) so it's more likely that the Keytruda wasn't a good match to kill the cancer.
