Christine has given you great advice. I'm adding a few things from our experience.

Before starting treatment, my husband sought out a second opinion at a CCC. The team brought up the PEG issue. They emphasized that some patients are physically unable to safely swallow at some point during treatment. They emphasized that it is not always a matter of will. I don't understand threatening a patient about this.

My husband had PEG placed before tx. He started using it after week three. He lost zero pounds because of it and I believe that helped him recover. He is able to eat all foods with liquid.

Hope you are able to get this resolved,
Lottie
