Hi @tiffboss : My brother has been treated for stage 4 pancreas cancer at the University of Iowa Hospitals and Clinics for the past two years. We have found them to be efficient, caring and responsive. My brother sees Dr. Berg and his PA and both have been very good. I hope that you have the same experience. When my brother was diagnosed he too had arterial involvement with the cancer but did 9 rounds of Folfirinox and then had 5 weeks of MRI guided radiation. He then underwent a Nanoknife operation with Dr. Chan. Hopefully your chemo will shrink the mass small enough that surgery is an option. Positive thoughts sent your way.....
