Strange...I had Stage 4 as well, and immunotherapy was not even on the table.

Radiation...the gift that keeps on giving. Several months out from the completion of therapy ending last July, I thought I was on the road back to life as I knew it. Putting on weight, getting stronger, eating normally again and life was good. Then, at the end of January, my oncologist informed me on a regular visit that due to scarring and inflammation, he was highly concerned the narrowing he saw when he scoped my throat, would suffocate me. He said he couldn't morally let me leave in such a state. Emergency trachea operation soon ensued.

I still can't eat or drink (have feeding tube). I have trouble speaking, and breathing is compromised. Side affects from radiation could go on for several years or more. You never know what could be around the corner. I don't know weather I'll ever be able to eat or have this tube removed. The doctors sure don't want to comment on it.

Looking back, I don't know if I made the right decision. Mere days before I was out with some friends on our ATV's clearing trails, sawing and removing fallen trees. Very active with no breathing issues apparent to me up to that point.

Funny thing about all of this. I have never gave much thought through all of this, to the cancer. It's the after affects of the treatment that has always concerned me. I have made it clear that I will not do any more radiation therapy.

So far there has been no side affects from the Keytruda. Good to here that this has been effective for many people. Best wishes on your situation.
