Despite rare, metastatic anal carcinoma confers a poor prognosis. Systemic chemotherapy is the mainstay of treatment for advanced disease while the role of biologics and/or surgical resection of metastatic disease are anecdotal. Compared to isolated liver colorectal or neuroendocrine cancer liver metastases, there is far less experience with resection or nonsurgical local ablative procedures for patients with metastatic anal carcinoma to the liver. We report the case of a 67-year-old woman with metastatic anal carcinoma to the liver who was successfully treated with liver resection and remains free of relapse more than one year later...

A 78-year-old man was admitted to our hospital for multiple lung and liver tumors. Initial clinical diagnosis was hepatocellular carcinoma (HCC) with lung metastases because of a high value of serum protein induced by vitamin K absence or antagonist II (PIVKA-II) (6,705 mAU/mL). However, a review of a prior CT showed the lung tumor had existed 6 months before liver tumors were detected. The tumors progressed rapidly and the patient died 37 days after admission. Autopsy revealed that both lung and liver tumors exhibited the histology of large cell neuroendocrine carcinoma (LCNEC)...

Selective internal radiation therapy (SIRT) of hepatocellular carcinoma has been introduced at Aarhus University Hospital. 90Y-microspheres are implanted in the tumour by catheterization of the tumour feeding liver artery. Pretreatment angiography and test treatment using 99mTc-labelled particles followed by scintigraphy ensure a feasible and effective treatment. Post-treatment imaging of radiation from 90Y visualize the localization of microspheres. Currently, SIRT is also applied for liver metastases of neuroendocrine tumours...

BACKGROUND: Patients with somatostatin receptor-expressing neuroendocrine tumours can be treated with intravenously administered (177)Lu-octreotate. Few patients are cured with the present protocol due to the current dose limitation of normal organs at risk, such as the kidneys. By locally administering (177)Lu-octreotate to the liver for the purpose of treating liver metastases, a substantially reduced absorbed dose to organs at risk could be achieved. The development of such a technique requires the capability of measuring the (177)Lu activity concentration in tissues in vivo...

Background Visual semi-quantitative assessment of liver tumour burden for neuroendocrine tumour liver metastases is often used in patient management and outcome. However, published data on the reproducibility of these evaluations are lacking. Objective The aim of this study was to evaluate the inter and intraobserver agreement of a visual semi-quantitative assessment of liver tumour burden using CT scan. Methods Fifty consecutive patients (24 men and 26 women, mean age 54 years old) were retrospectively reviewed by four readers (two senior radiologists, one junior radiologist and one gastroenterologist) who assessed the liver tumour burden based on visual a semi-quantitative method with four classes (0-10%, 11-25%, 26-50%, and ≥50%)...

BACKGROUND: Long-term term survival in patients with pancreatic neuroendocrine tumors has been reported, even in patients with metastatic disease. Metastases to the spleen are extremely rare, but have been reported from a number of primary malignancies, such as breast cancer, lung cancer, melanoma and ovarian cancer. This is the first report of a splenic metastasis from a primary pancreatic neuroendocrine tumor. CASE PRESENTATION: The patient presented as a 53 years old white male with anemia and fatigue...

Dear Editor The incidence of small intestinal neuroendocrine tumours (SINETs) is increasing and distant metastases are present at diagnosis in 70% of cases, the liver being the most common site of metastasis. Despite this, our understanding of the mechanisms underlying metastatic progression of SINETs is currently limited and prior studies of the molecular biology of SINET liver metastases (LM) have been performed predominantly in small cohorts utilising candidate based techniques.

BACKGROUND: Treatment for midgut neuroendocrine tumor patients with unresectable liver metastasis has long been a controversial issue. This system review aims to summarize existing evidence concerning the value of primary tumor resection in this group of patients. RESULTS: 8 cohort studies were identified for qualitative analysis. None of them strictly met with the inclusion criteria and meta-analysis was impossible. There was a tendency towards better overall survival for the primary tumor resected group in all 8 studies, in which 6 demonstrated significant difference...

Neuroendocrine tumors (NETs) of the gastrointestinal tract are a rare and heterogeneous group of neoplasms with unique tumor biology and clinical management issues. While surgery is the only curative treatment option in patients with early stage NETs, the optimal management strategy for patients with advanced metastatic NETs is unknown. Based on the tremendous success of immunotherapeutic approaches, we sought to investigate such approaches in a case of metastatic rectal NET. Here, we apply an integrative approach using various computational and experimental methods to explore several aspects of the tumor-host immune interactions for immunotherapeutic options...

Liver magnetic resonance imaging (MRI) is becoming the gold standard in liver metastasis detection and treatment response assessment. The most sensitive magnetic resonance sequences are diffusion-weighted images and hepatobiliary phase images after Gd-EOB-DTPA. Peripheral ring enhancement, diffusion restriction, and hypointensity on hepatobiliary phase images are hallmarks of liver metastases. In patients with normal ultrasonography, computed tomography (CT), and positron emission tomography (PET)-CT findings and high clinical suspicion of metastasis, MRI should be performed for diagnosis of unseen metastasis...

BACKGROUND: Functional well-differentiated neuroendocrine tumours (NET) with liver metastases represent a therapeutic challenge with few alternative options in guidelines. In these patients, the role of surgical resection of the primary tumour is controversial. PATIENTS AND METHODS: From a regional registry collecting somatostatin analogue (SSA)-treated tumours from 1979 to 2005, a series of 139 patients presenting with symptomatic, liver-metastatic, well-differentiated NET (G1-G2, mitoses: ≤20, Ki-67: ≤20%) was prospectively collected and retrospectively analysed...

Neuroendocrine tumors in the digestive tract are rare, however their incidences increased obviously for the past few years. The purpose of this paper is to elucidate the surgical management of locally advanced digestive tract neuroendocrine neoplasms(NENs) with or without liver metastasis and to discuss the present classification of gastrointestinal NENs in order to provide reference for clinicians. WHO re-classified the gastroenteropancreatic NENs in 2010, but this classification remains many questions and needs further clinical trials to answer...

Background: Non-functional neuroendocrine tumors of the pancreas (NF-pNETs) are a varied group of extremely rare malignancies. The majority of patients already have liver metastases at the diagnosis moment, thus, treatment options are restricted, and the survival rate is reserved. Case report: We presented the case of 59-year-old patient, diagnosed with non-functional well-differentiated pancreatic neuroendocrine tumor grade II (NET G2) with the presence of chromogranin A, synaptophysin and somatostatin receptor 2, together with liver and bone metastases...

PURPOSE OF THE REPORT: Peptide receptor radionuclide therapy (PRRT) is an effective treatment for advanced neuroendocrine tumors (NET); however, long-term survival data are scarce. The aim of this study is to determine long-term survival in patients with metastatic midgut NET, according to response to PRRT. PATIENTS AND METHODS: One hundred thirty-three consecutive patients with progressive metastatic midgut NET underwent PRRT. Response at 1 year post PRRT was classified as partial response, stable disease, disease progression, or death...

Hepatic metastases are one of the most important prognostic factors for survival among patients affected by gastrointestinal neuroendocrine tumors (NETs). The present study aims to evaluate the impact of surgery, including hepatic resection or orthotopic liver transplantation (OLT), on the outcome of patients affected by hepatic metastases from NETs, in terms of overall survival (OS). In this multicentric retrospective study, data was collected on 26 patients, who underwent surgery for hepatic metastases from NETs in two Italian University Clinics between January 1990 and December 2012; of which, 22 patients underwent hepatic resective surgery and 4 patients OLT...

Patients with noncolorectal hepatic metastases often face limited treatment options and a dismal prognosis. Over the last decade, the advent of targeted immunotherapies has transformed the treatment of certain metastatic cancers, such as sarcoma and melanoma; however, these patients eventually develop resistance. Metastatic sarcoma, melanoma, and breast and neuroendocrine tumors are notoriously treatment resistant once they have metastasized to the liver. For these cancers, minimally invasive transarterial and ablation therapies have emerged as safe, palliative therapies that can provide symptom control and even prolong survival...
