Long Term Survival after Transplant for Neuroendocrine Liver Metastases: A Case Report and Literature Review Abstract #2225

Introduction: Liver transplantation (LT) is offered to selected patients of neuroendocrine tumours (NETs) with unresectable liver metastases (NELM).
Aim(s): To present a case of long term survival after recurrence in transplanted liver.
Materials and methods: A 35 year old lady with recurrent upper abdomen pain had multiple bilobar cystic liver lesions on computed tomogram. Fine Needle Aspiration Cytology showed NET. Serum Chromogranin A (S. CgA) was raised and DOTA-PET showed bilobar NELM with unknown primary. Patient underwent Exploratory Laparotomy, and a 1 X 1.5 cm exophytic lesion was found 30cm from DJ flexure. Resection and anastomosis was performed. Histopathology revealed grade 1 NET. Patient underwent LT 6 months later, and was disease free for 5 years. CT and DOTA-PET done 5 years after transplant revealed multiple DOTA positive liver lesions, and S. CgA was raised. She underwent 3 cycles of 177-Lu PRRT, after which the lesions increased in size. She was put on long-acting depot Octreotide (LAR) for 6 months. 2 years after stopping LAR, she presented with carcinoid syndrome and raised S. CgA. She was again put on LAR. Now the patient is being considered for 213-Bismuth PRRT for growing liver metastasis, 11 years after first diagnosis.

#62 Genome-wide DNA methylation profiling of pancreatic neuroendocrine tumors identifies distinct methylation profiles and differentially methylated gene promoter regions associated with low, medium and high grade tumors
Introduction: Integration of genetics and epigenetics has emerged as a powerful approach to studying cellular differentiation (Mikkelsen et al, 2009) and tumorigenesis (Shen et al, 2007). The study of DNA methylation is of particular importance in cancer, as causal involvement has been demonstrated and it is the most stable of all epigenetic modifications, making it a desirable marker for both early detection and treatment of tumors. Hypermethylation of CpG sites in gene promoter regions leads to decreased gene expression; if such a gene is a tumor suppressor, this leads to carcinogenesis. To date, there have been no studies of genome-wide DNA methylation profiling of NETs. This study sets out to determine the DNA methylation profiles of low, intermediate and high grade pancreatic NET liver metastases with the intention of identifying dysregulated biological pathways in the development of these tumors. A protocol for the analysis formalin-fixed paraffin embedded tissue (FFPE) has also been developed in order to study these tumors in significant numbers following this pilot study.

#133 Effectiveness of transarterial embolization of liver neuroendocrine metastases
Introduction: Neuroendocrine tumors (NETs) with diffuse liver metastases have a poor prognosis and prove difficult to palliate. Somatostatin analogues and chemotherapy have been used but often are poorly tolerated and may not provide symptom relief. Transarterial Embolization (TAE) is being increasingly used to improve symptom control and reduce tumor size. We looked at the last 5-year experience of TAE in patients with hepatic metastases from neuroendocrine tumors.

Introduction: Although liver transplantation is a valid option in the treatment of metastasized neuroendocrine tumors, it is not promoted because of a donor organ shortage and disappointing results in older series.
