Adenocarcinoma (2002)

Record number: 
Adverse Occurrence type: 
MPHO Type: 
Estimated frequency: 
Tumor was of unknown primary site but presence in liver and donor elevation of Ca19.9 is suspicious for biliary origin. Most recent risk assessment (Council of Europe, 2022): Oesophageal, gastric, pancreatic, liver and biliary cancers diagnosed during donor procurement : These tumours are classified as unacceptable risk. Oesophageal, gastric, pancreatic, liver and biliary cancers in the donor history: Treated tumours of these kinds in the donor history are classified as high risk due to their aggressive behaviour. Risk may decrease for early stages after curative therapy, with recurrence-free time > 5 years and with increasing probability of cure, especially in cases of long-term survivors.
Time to detection: 
12 months
Alerting signals, symptoms, evidence of occurrence: 
Liver ultrasound of the anastomoses showed a 1.5 cm mass. Biopsy showed a moderately differentiated mucin secreting adenocarcinoma.
Demonstration of imputability or root cause: 
Tumor, donor, and recipient DNA was isolated from the parafin embedded liver biopsy, pretransplant liver donor biopsy and explanted liver tissue, respectively. Microsatellite analysis was performed by polymerase chain reaction (PCR) using 5 markers: D5S346, ACTC, D2S123, D18S34, and TP53. The allelic patterns of tumor DNA were identical to those of donor DNA and were distinct from the DNA profile of the recipient.
Imputability grade: 
3 Definite/Certain/Proven
