I have to think of another phrase for “welcome”; because the fact you are here on its face value is not exactly welcoming! It’s a group where you are among online friends and you will gain a considerable wealth of knowledge regarding different line of treatments. Duke is obviously a great university (have a niece that went there) and important to remember to try and go with a practitioner (surgeons and oncologists) with a lot of experience on the books. There are patients on this forum where cancer has wrapped around an artery (which one?) and get surgery after chemo. I believe Dr. Trudy at Mayo in Rochester is one of those places, but you can search for a topic of a specific discussion on this forum to find out for sure. Hoping you have a good journey and never be afraid to ask questions from your dr and do a lot of research which you can get started on just by reading these discussions.

Dr. Christopher Wolfgang at NYU Langone is highly regarded for his success taking on complicated Whipples, including (I think) those with arterial involvement. Might be worth a call or visit.
