Liver Transplantation for Hilar Cholangiocarcinoma Mary Douglas, RN, MSN,CCTC Clinical Transplant Coordinator University of Wisconsin- Madison
Case Study • 44 yo male with PSC/ UC. • Dx with UC age 37, PSC at age 42 • ERCP 5 years after diagnosis revealed adenocarcinoma via brushings • FISH positive for polysomy • Presented with weight loss, obstructive jaundice and abdominal discomfort
Diagnosis of Cholangiocarcinoma • CCA is slow growing tumor that invades adjacent neural, lymphatic and hepatic tissue. Intertwining with bile ducts. • Brushings are 50% accurate, now use FISH ( fluorescence in situ hybridization) • Median survival of unresectable disease with only XRT is 9-12 months. • With surgical resection, median survival is 11-38 months with 5 year survival at 5-20%
Liver Transplantation • 1980’s Liver txp was used for unresectable tumor, only 10-20% survived >5years. • CCA –contraindication for oltx
Mayo Protocol • 1993 • Diagnosis of CCA established- • Biopsy( transluminal) positive for cancer • Positive or suspicious cytology on brush cytology • Stricture, and FISH polysomy • Mass lesion on cross-sectional imaging • Malignant-appearing stricture and CA19-9>100 or FISH polysomy
Indeterminate Diagnostic Criteria • FISH trisomy ( 7 or 3) • Dysplasia • DIA>1.8 in isolation(FISH neg,cyt neg) • FISH polysomy in absence of malignant-appearing stricture • Malignant-appearing stricture in absence of mass lesion, positive cytology, biopsy, elevated CA19-9 or FISH polysomy
Prior to protocol • EUS guided regional lymph node aspiration routinely before beginning neoadjuvant therapy. • The identification of lymph node metastases obviated the need for exploratory laparotomy and disqualified the patients from subsequent liver transplantation • With the introduction of EUS in 2002, the percentage of patients with a positive staging laparotomy has decreased from 30 to 15%.
Mayo Protocol Neoadjuvant Therapy • Neoadjuvant therapy (4000-4500 cGy) is administered by external beam radiation in 30 fractions • Followed by transcatheter radiation (2000-3000cGy) with iridium-192 wires( brachytherapy) • These wires placed by ERCP or PTC • Infusional 5-FU is given during XRT, followed by oral capecitabine after the radiation therapy until the day of oltx.
Protocol • Staging laparotomy is preformed upon completion of neoadjuvant radiotherapy. Usually within 2-3 weeks after brachy therapy. • This involves complete abdominal exploration with biopsy of any lymph nodes/nodules suspicious for tumor, examination of tumor, and routine biopsy of regional lymph nodes. At least one lymph node must be taken. (laparoscopic?) • If negative staging operation, then eligible for listing for OLTX • MELD exception=22 in Region 7. 10% MELD upgrade every 3 months if not transplanted
Liver Transplantation • If LRD, do staging operation 1-2 days prior • If CAD, stage, waitlist, MELD exception • During oltx, if there is microscopic tumor involvement, a pancreaticoduodenectomy is also preformed • Unique complications with LRD vs. CAD with vessels due to XRT exposure.
Outcomes • 1993-2008:167 patients • 12 deaths,2 txp elsewhere,10 received neoadjuvant rx. • 143 had irradiation and 5FU and staging • 27 were positive (19%), 2 waitlist, 1 death, 2 txp elsewhere • 111 transplants, 75 CAD,35 LRD,1 domino
Outcomes • 1 -,3-, and 5-year patient survivals after the start of therapy(167) are 84%, 64% and 56%. • 1-,3-,and 5-year patient survivals after liver transplantaion ( N=111)are 96%, 83%, and 72%. No difference in survival regarding LRD vs.CAD • There have been 15 recurrences in 111 oltx (14%), occurring at a mean of 25 months after oltx (range: 7-64 months).
Organ Allocation • To get MELD exception: • Transplant center submit formal patient care protocols to UNOS Liver /Intestinal Committee • Candidates satisfy accepted diagnostic criteria for CCA and be considered un-resectable on basis of technical considerations or underlying liver disease (PSC) • tumor mass <3cm diameter on imaging • imaging studies to r/o mets • negative exploratory lap • primary tumor cannot be biopsed
Further investigations • OLTX is superior in outcomes to resection • Should this therapy be applied to other patients without liver disease ( PSC)? • Neoadjuvant therapy with XRT can damage bile ducts, which precludes biliary reconstruction after resection.
Summary • Role of oltx in setting of CCA has undergone radical changes in past 20 years. • With rigorous patient selection,neoadjuvant XRT, operative staging and oltx, the protocol has achieved a 72% survival at 5 years. • We need to continue to work on advances in XRT, chemo agents, protocol development • Future role of this therapy for patients with resectable tumors, but outcomes not as positive as in liver transplantation.
Patient Case Study • Patient went thru this protocol, exploratory lap was negative. MELD=22 • Got exception to 25 after 3 months • Transplanted 4 months after getting to list • CA19-9=125. Age<45 • Out 3 years to date. No recurrence
