Carlene….welcome to our group. As you may already know, gastric cancer patients, including those with cholangiocarcinoma, can have a tendency to develop Portal Vein Thrombosis. You may want to enter the keyword into the “search” function, top bar, for previous discussions about this issue.
In regards to the CA 19-9, certain people lack a specific antigen, hence there is no elevation in the tumor markers.
As always I would love for other members to come forward and to share their experiences with us.
Hugs,
Marion
