I found this clinical trial at the University of Utah:
Liver Transplantation for Cholangiocarcinoma
http://clinicaltrials.gov/ct2/show/study/NCT00708877
They accepted patients with some lymph node metastasis:
Quote:
Patients with extrahepatic metastases, local spread of disease to adjacent organs, and N2 nodal disease (metastasis to peripancreatic, periduodenal, periportal, celiac, superior mesenteric, and / or posterior pancreaticoduodenal nodes) will be excluded as will patients with extension of tumor into the main portal vein. Patients with N1 disease (metastasis to lymph nodes within hepatoduodenal ligament) will remain eligible for the protocol.
That was actually part of the trial. It’s not a standard protocol.
