My husband is Stage 4, MSI-High, and has been on Keytruda (pembrolizumab) for several months now. Generally, it’s going well, much better than chemo side effects would likely be. Main issue is fatigue and occasional mild rash. Curious about others’ experiences with immunotherapy (Keytruda, Opdivo, etc.) - what side effects did you encounter? Anything unexpected pop up later? How severe were they?
Also MSI-stable, so no firsthand immunotherapy experience, but sending positive thoughts for continued success with Keytruda for your husband, Karen! Fatigue is just part of the cancer battle, regardless of treatment type, it seems.
