Thank you all for your responses. I do believe that my brothers primary doctor is is at the Norris Center in Los Angeles, but not sure. I do know that initially he did go for 2nd and 3rd opinions about surgery but was told until the tumor shrunk they wouldn’t attempt it and also from the tumor there were tendrils that wrapped around several lymph nodes as well. I would welcome the names of any doctors in the Los Angeles area who are specialist in this cancer. As for infections, he’s always told that its from the stents and further complications come from the antibiotics killing his immune system. With exterior drain in place now maybe things will improve.
