Successful liver transplantation as rescue therapy in a patient with metastases from a vasoactive intestinal peptide producing neuroendocrine tumor.

ABSTRACT

This case report presents a 40-year-old patient with a vasoactive intestinal peptide (VIP) secreting high grade (Ki-67 39%) neuroendocrine tumor (NET) from the pancreas, for whom successful liver transplantation (LT) was carried out 8 years after resection of the primary tumor due to massive liver metastases. The transplantation was done as rescue therapy due to rapid progression and a devastating clinical condition requiring intravenous supplementation for 20 hours daily. The latest imaging carried out 18 months after transplantation is without signs of recurrence, and the patient is in good health with undetectable levels of VIP. According to the guidelines, LT is only recommended if Ki-67 is <20% and if there has been tumor control for more than 6 months prior to transplantation. Our case illustrates that LT is an option that should be considered for selected NET patients without extrahepatic involvement regardless of tumor grade and clinical condition.
