I had good results from Keytruda for a year for my throat cancer. Little to no side effects from what I remember. I was put on a different immunotherapy that was ineffective and caused a skin breakouit that requiredconstant attention. This treatment was ineffetive. Since then they put me on Opdivo and I have had smooth sailing for 10 Petscans with no side effects. I'm pretty sure my luck with Opdivo will run out one day, so I'm just enjoying this ride for now. The docs have a multitude of answers and each one of us is a custom application. Sometinmes it takes time to find the right individual solution. I'm just hopin g I can continue on they find a mor epermanent solution to my chronic cancer. Keep faith in your team. They will work hard and never give up.
