Liver transplant is now an acceptable and effective treatment for specific nonhepatocellular malignancies. Worldwide, hilar cholangiocarcinoma accounts for 3% of all primary gastrointestinal malignancies and for 10% of primary hepatobiliary malignancies. For patients who have early-stage, unresectable cholangiocarcinoma, liver transplant preceded by neoadjuvant radiotherapy can result in tumor-free margins, accomplish a radical resection, and treat the underlying primary sclerosing cholangitis when present...

REVIEW
Nobuyuki Takemura, Akio Saiura
It is widely accepted that the indications for hepatectomy in colorectal cancer liver metastases and liver metastases of neuro-endocrine tumors result in relatively better prognoses, whereas, the indications and prognoses of hepatectomy for non-colorectal non-neuroendocrine liver metastases (NCNNLM) remain controversial owing to the limited number of cases and the heterogeneity of the primary diseases. There have been many publications on NCNNLM; however, its background heterogeneity makes it difficult to reach a specific conclusion...

OBJECTIVE: To assess if surgery for Multiple Endocrine Neoplasia type 1 (MEN1) related nonfunctioning pancreatic neuroendocrine tumors (NF-pNETs) is effective for improving overall survival and preventing liver metastasis. BACKGROUND: MEN1 leads to multiple early-onset NF-pNETs. The evidence base for guiding the difficult decision who and when to operate is meager. METHODS: MEN1 patients diagnosed with NF-pNETs between 1990 and 2014 were selected from the DutchMEN1 Study Group database, including > 90% of the Dutch MEN1 population...

A 53-year-old man presented with diarrhoea and hypokalaemia and was diagnosed with a neuroendocrine tumour of unknown origin with multiple liver metastases. Somatostatin analogues led to a reduction in the size of the tumours and improvement of his symptoms. However, after several years, the tumours grew in size, and the patient's clinical symptoms recurred. The patient underwent transcatheter arterial embolization (TAE) of the hepatic artery to treat the liver metastases. Immediately after embolization, the symptoms disappeared...

We examined somatostatin receptor type 2A (SSTR2A) expression in primary and metastatic small intestinal neuroendocrine tumors (SI-NETs). We retrieved 156 liver metastases from 26 patients (10 males, 16 females) who had two or more liver lesions resected. A representative formalin-fixed paraffin-embedded section of tumor tissue from each liver metastasis and from the primary tumor, when available, were immunohistochemically stained for SSTR2A. SSTR2A expression was evaluated by the Her2/neu-scoring system and the scoring system proposed by Volante et al...

BACKGROUND: Isolated liver metastases occur rarely in patients with metastatic breast cancer. The success of liver resection (LR) for other metastatic disease has led centres to explore the option of LR for patients with isolated breast cancer liver metastases (BCLM). A number of small series have been published in the literature, however the evidence is conflicting. This study aimed to systematically review the literature to determine the perioperative outcome and survival of patients undergoing LR for BCLM...

RATIONALE: Pancreatic neuroendocrine tumors (pNET) are rare slowly growing tumors with a high metastatic potential. Peptide receptor radionuclide therapy (PRRT) with radiolabeled analogues has been developed as a new tool for the management of metastatic well-differentiated (grade 1 and 2) neuroendocrine tumors expressing somatostatin receptor (SSTR2). Chemotherapy is the mainstay in the management of grade 3 (G3) unresectable pancreatic neuroendocrine carcinoma (pNEC). To date, no study has evaluated the efficacy of PRRT in such tumors...

BACKGROUND: Routine screening is recommended for patients with multiple endocrine neoplasia type 1 (MEN1) to enable early detection and treatment of associated neuroendocrine neoplasms (NEN). Gallium(68)-DOTATOC-Positron emission tomography combined with computed tomography (Ga-68-DOTATOC-PET-CT) is a very sensitive and specific imaging technique for the detection of sporadic neuroendocrine tumors. The present study evaluated the value of Ga-68-DOTATOC-PET-CT in routine screening of patients with MEN1...

AIM: Besides the use of somatostatin analogues, small molecules like sunitinib and everolimus as well as conventional chemotherapy, peptide receptor radiotherapy (PRRT) using radiolabelled somatostatin analogues has gained an important role in the treatment of inoperable, metastasized neuroendocrine tumours (NET). There are various radiotracers in use. Based on our experience with the PET tracer [(68)Ga]DOTA-3-iodo-Tyr(3)-octreotate ([(68)Ga]HA-DOTATATE), a DOTATATE derivative with an increased binding affinity to hsst5, the current retrospective analysis is exploring the therapeutic potential of [(177)Lu]HA-DOTATATE...

A 50-year-old man was diagnosed with multiple bilobar liver metastases of rectal neuroendocrine tumor(NET). Although he received octreotide for 6 months and everolimus for 10 months, the liver metastases gradually increased in size. Therefore, we decided to perform transcatheter arterial infusion(TAI)with miriplatin. The serum total bilirubin level increased to 13.1 mg/dL 9 days after treatment, and it took 2 months to return to the normal range. CT scan demonstrated that most of the liver tumors had remarkably shrunk 4 months after treatment, and the patient has no sign of tumor regrowth even 12 months after treatment...
