Glad you are holding your own, so far. As far as Peg Tubes, as we formally call it PEG Wars lol. I didn't have one when I did induction chemo in November 2009, but did eventually need after being hospitalized for a long duration from that, and being NPO. I had the peg taken out when I was NED 7 month later, but had a recurrence, and my swallowing was still compromised, and another was suggested to be put in, and did, which I still have, and used during several other treatments through the years, and still lost 40 pounds with my first radiation, and was tube dependent for that, but not any others.
It also depends if the person is already compromised, eating inability, having invasive surgery, is underweight or not going to be able follow the proper nutrition, hydration, and mouth exercise regimine that one may be suggested to have put in before starting treatment. It seems these days it is favored by some doctors, and even patients, to have one put in reactively, than proactively, and some not at all. There are pros and cons to each.
Keep up the good work, Doctor.
