Forget the PEG, at this stage in the treatment he should consider getting a nasal tube. It is just fed through a nostril down into his stomach (I had one) and x rayed to make sure it's positioned correctly. Then the thin metal stip included in the tube for the purpose of giving the tube ridigity so it can be inserted and for the positional x ray, is merely pulled out. Took them 2 mins or less to insert and I kept it for 2 weeks and it saved my stubborn butt. He would most likely have to keep it a tad longer but it will be well worth it.

Re the 3rd chemo of I assume Cisplatin, many have not had it but this definately needs to be discussed with his chemo and rad doc. As has been said the last of the rads are more important than the chemo but let's see what the docs say. Some have been switched to Carboplatin for the last one so inquire about that if it's not brought up.

The few weeks POST radiation are usually the worst time for everyone so be prepared. IMO that's why it's critical to get that nasal tube in now. He needs at least 3000 cals and 48 ozs of water each and every day and the tube makes acheiving that goal soooo much easier.

Welcome to this site. It will be worth it's weight in gasoline.
