BACKGROUND: Genetic analysis of advanced cancer is limited by availability of representative tissue. Biopsies of prostate cancer metastasized to bone are invasive with low quantity of tumor tissue. The prostate cancer genome is dynamic, however, with temporal heterogeneity requiring repeated evaluation as the disease evolves. Circulating tumor cells (CTCs) offer an alternative, "liquid biopsy", though single CTC sequencing efforts are laborious with high failure rates. METHODS: We performed exome sequencing of matched treatment-naïve tumor tissue, castrate resistant tumor tissue, and pooled CTC samples, and compared mutations identified in each...

AIM: To provide more information and therapeutic methods about gastric neuroendocrine carcinomas (G-NECs) which occur rarely but are highly malignant and clinically challenging. METHODS: We retrospectively analyzed the clinicopathological characteristics, treatments, and prognosis of 43 G-NEC patients at our hospital between January 2007 and December 2014. The diagnosis was based on the 2010 World Health Organization criteria. RESULTS: Forty-three G-NECs containing 39 small cell carcinomas and 4 large cell NECs with Ki67 > 60% were included in this study, accounting for only 0...

BACKGROUND: While neuroendocrine (carcinoid) tumors are increasingly recognized in the adult population, they are often not suspected in children. PROCEDURE: Retrospective review of all well-differentiated neuroendocrine (carcinoid) tumors was performed based on pathology reports from a quaternary pediatric medical center between January 2003 and June 2016. Clinical presentations, treatment approaches, imaging findings, and outcomes were reviewed and analyzed. RESULTS: A total of 45 cases of pathology-proven carcinoid tumor were reported with an average age of 14...

BACKGROUND: Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are rare neoplasms and data on peritoneal metastases (PM) from these tumors are scarce. OBJECTIVE: The aim of this study was to present population-based data on the incidence, risk factors, and survival of synchronous PM in GEP-NETs. METHODS: Data from all patients diagnosed with a GEP-NET during 2007-2013 were collected from the Netherlands Cancer Registry. Age-standardized incidence rates were calculated and risk factors for developing PM were determined using multivariable logistic regression analysis...

Peptide receptor radionuclide therapy (PRRT), developed over the last two decades, is carried out using radiopharmaceuticals such as 90Y-DOTA-Tyr3-octreotide and 177Lu-DOTA-Tyr3-octreotate (177Lu-Dotatate). These radiocompounds are obtained by labeling a synthetic somatostatin analog with a β-emitting radioisotope. The compounds differ from each other in terms of their energetic features (due to the radionuclide) and peptide receptor affinity (due to the analog) but share the common characteristic of binding specific membrane somatostatin receptors that are (generally) overexpressed in neuroendocrine neoplasms (NENs) and their metastases...

BACKGROUND: An accurate diagnosis of cancer of Müllerian origin is required before the initiation of treatment. An overlap in clinical presentation and cytological, histological, or imaging studies with other nongynecological tumors does occur. Therefore, immunocytochemistry markers are used to determine tumor origin. Human epididymis protein 4 (HE4) is overexpressed in tissue of epithelial ovarian cancer (EOC). It has shown to be a sensitive and specific serum marker for EOC and to be of value for the differentiation between EOC and ovarian metastases of gastrointestinal origin...

Olfactory neuroblastoma (ONB) is a rare malignant neoplasm of the sinonasal tract that arises from olfactory epithelium. There have been reports, mainly in tumors treated with chemoradiation or with distant metastases, describing focal histologic changes of divergent cell populations within archetypal ONB. Only three cases have been reported of ONB coexisting with non-neuroendocrine tumors. We describe our experience with a 35-year-old male with a nasal cavity mass extending into the anterior cranial fossa...

: Localization of the site of the unknown primary tumor is critical for surgical treatment of patients presenting with neuroendocrine tumor (NET) with metastases. METHODS: A single-center prospective study was performed to evaluate the safety and efficacy of (68)Ga-DOTATOC PET/CT in patients with diagnosis of or suspected NET. A subgroup of patients with metastases and unknown primary after initial work-up was analyzed. The ((68)Ga)Ga-DOTATOC PET/CT was considered true positive if the positive primary site was confirmed by histology or follow-up imaging...

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...

A 62-year-old woman was diagnosed with carcinoma of the stomach at another hospital. Distal gastrectomy with D2 dissection was performed and she was referred to our hospital. Histopathological and immunopathological examinations showed the tumor to be composed of adenocarcinoma and neuroendocrine carcinoma. The patient was followed until 4 months after the operation when an abdominal computed tomographic(CT)scan showed a metastatic tumor at S2 and S5/6 of the liver. No other organ metastases were found, and a hepatectomy was performed...

New treatment options are needed for medullary thyroid carcinoma (MTC), a highly metastasizing neuroendocrine tumor that is resistant to standard radio- and chemotherapy. We show that the following shikonin derivatives inhibit cell proliferation and cell viability of the MTC cell line TT: acetylshikonin, β,β-dimethylacrylshikonin, shikonin and a petroleum ether extract of the roots of Onosma paniculata containing several shikonin derivatives. The unsubstituted shikonin derivative was found to be the most effective compound with an IC50 of 1...

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 carcinomas (NEC) of the pancreas are defined by a mitotic count > 20 mitoses/10 high power fields and/or Ki67 index > 20%, and included all the tumors previously classified as poorly differentiated endocrine carcinomas. These latter are aggressive malignancies with a high propensity for distant metastases and poor prognosis, and they can be further divided into small- and large-cell subtypes. However in the NEC category are included also neuroendocrine tumors with a well differentiated morphology but ki67 index > 20%...
