Large cell neuroendocrine carcinoma in the salivary glands is rare. We report a second case of large cell neuroendocrine carcinoma of the submandibular gland diagnosed at autopsy, and a review of the literature. A 68-year-old Japanese man was referred to our hospital for thorough investigation of swelling on the right side of his neck. Fine-needle aspiration cytology of the cervical mass suggested poorly differentiated metastatic carcinoma. The primary tumor could not be detected by several examinations. One month after admission, he died of cancer. An autopsy was performed, and it revealed a tumor of the right submandibular gland. The histopathological diagnosis was large cell neuroendocrine carcinoma of the submandibular gland. To the best of our knowledge, only eight cases of large cell neuroendocrine carcinoma in the salivary glands, including our case, have been reported. This report indicates total biopsy and immunohistochemistry are necessary for diagnosing large cell neuroendocrine carcinoma
Two mutually exclusive genomic LCNEC subtypes have been identified by molecular studies: one shows co-mutated TP53 and RB1, which is similar to SCLC, and the STK11/KEAP1 subtype with predominantly RB1 wild-type that is similar to NSCLC.. Reviewing clinical data and tumour specimens of 232 patients in the Netherlands Cancer Registry and Pathology Registry from 2003 to 2012, this retrospective analysis identified 148 patients who had been diagnosed with LCNEC. Of these, samples from all patients receiving first-line chemotherapy for panel-consensus diagnosed LCNEC were included for next-generation sequencing (NGS) for the TP53, RB1, STK11, and KEAP1 genes. RB1 (pRB1, 13A10) was analysed by immunohistochemistry, with samples having an H-score of ≥50 considered positive.. The results of the NGS and pRB1 were correlated with overall survival (OS) and progression-free survival (PFS) by Kaplan Meier plots and Log-rank test.. Quality control of the samples determined that 79 samples were sufficient ...
Patients who underwent chemotherapy had longer overall survival. Research presented in the July 2012 issue of the International Association for the Study of Lung Cancers (IASLC) Journal of Thoracic Oncology, concluded that patients with limited large cell neuroendocrine tumors or with limited stage small-cell lung cancer who were treated with perioperative chemotherapy and surgery had better overall survival outcomes than patients treated with surgery alone.. Small-cell lung cancer (SCLC) represents about 15 percent of lung cancers annually. Of those, about 30 percent of patients have limited disease SCLC. Whereas large-cell neuroendocrine carcinoma (LCNEC) is a subgroup of large-cell carcinoma, that has characteristics similar to SCLC. Surgery in these groups of patients are rare and researchers wanted to know if perioperative chemotherapy would benefit the patients.. The retrospective study looked at 74 patients who underwent lung cancer surgery at the Surgical Centre Marie Lannelongue in Le ...
In this study, we aimed to evaluate the data of patients diagnosed with primary breast neuroendocrine carcinoma.

4F2hc (CD98) has been associated with tumor growth, and is highly expressed in various tumors. The aim of this study was to evaluate the clinicopathological significance of 4F2hc expression in pulmonary neuroendocrine (NE) tumors. Surgically-resected patient tumors including 16 large cell neuroendocrine carcinoma (LCNEC), 12 small cell lung cancer (SCLC), 1 atypical carcinoid (AC) and 5 typical carcinoid (TC) samples were included in this study. Tumor sections were immunohistochemically stained for 4F2hc (CD98), glucose transporter 1 (Glut1) and 3 (Glut3), hypoxia-inducible factor-1α (HIF-1α), hexokinase I, vascular endothelial growth factor (VEGF), microvessel density (CD34), epidermal growth factor receptor (EGFR), Akt/mammalian target of rapamycin (mTOR) signaling pathway (p-Akt, p-mTOR and p-S6K) and for a cell cycle regulator (p53). 4F2hc was overexpressed in 0% of the pulmonary carcinoids (TCs and ACs), 62.5% of the LCNECs and 50.0% of the SCLCs.

Large cell carcinoma now includes five variants in addition to large cell carcinoma defined as undifferentiated malignant epithelial cells. Two variants are recognized, both with dismal prognosis, LCNEC and basaloid carcinoma.. The concept of neuroendocrine tumours has been examined as a spectrum extending from low grade typical carcinoid to intermediate grade atypical carcinoid to high grade neuroendocrine tumours including large cell neuroendocrine carcinoma and small cell lung carcinoma (SCLC). Because of differences in clinical behaviour, therapeutic implications, and epidemiological context, these tumours have been presented separately in the WHO revised classification.. Typical and atypical carcinoid have been more precisely defined and clearly differentiated from each other with more objective criteria. Typical carcinoids have ,2 mitotic figures per 2 mm2, and have no necrosis. The presence of necrosis, or a mitotic count between 2-10·2 mm−2, allows separation of atypical carcinoid ...

We hereby report an unusual case of combined carcinoma of the larynx; composed mainly of small cell neuroendocrine carcinoma nearly confined to the right side (mainly involving supraglottis extending to glottis) with synchronous minor in-situ and invasive squamous cell carcinoma component located on the left side of larynx (mainly glottis). Interestingly, this side-specific distribution of tumor was recapitulated in its metastatic nodal spread; so that right cervical lymph nodes showed only metastatic small cell carcinoma and left cervical ...
The synchronous primary lung tumors is a rare condition and presented patient is the first reported case of simultaneous two distinct neuroendocrine lung cancer lesions in the same lobe. We present the case of a 55-year-old woman with synchronous two distinct neuroendocrine lung cancer lesions in the right upper lobe. Initially she showed no signs or symptoms related to lung lesions and was admitted to Thoracic Surgery Ward for the investigation of two oval, solitary pulmonary nodules (11 and 19 mm in diameter) detected on a chest X-ray performed three months earlier. The radiological imaging showed a variability of growth of both lesions (smaller tumor has enlarged while the larger one remained unchanged). After the CT-guided lung biopsy, patient underwent right upper lobectomy. Histological examination revealed a small cell carcinoma in one of the tumors and a large cell neuroendocrine carcinoma in the other one. The patient was discharged in good condition and lung inflation in chest X-ray ...
Background: Clarifying the prognostic impact of histological type is an essential issue that may influence the treatment and follow-up planning of newly diagnosed cervical cancer cases. This study aimed to evaluate the prognostic impact of histological type on survival and mortality in patients with cervical squamous cell carcinoma (SCC), adenocarcinoma (ADC) and small cell neuroendocrine carcinoma (SNEC). Materials and Methods: All patients with cervical cancer diagnosed and treated at Chiang Mai University Hospital between January 1995 and October 2011 were eligible. We included all patients with SNEC and a random weighted sample of patients with SCC and ADC. We used competing-risks regression analysis to evaluate the association between histological type and cancer-specific survival and mortality. Results: Of all 2,108 patients, 1,632 (77.4%) had SCC, 346 (16.4%) had ADC and 130 (6.2%) had SNEC. Overall, five-year cancer-specific survival was 60.0%, 54.7%, and 48.4% in patients with SCC, ADC ...

BACKGROUND: Recent studies suggest that insulinoma-associated protein 1 (INSM1) is a sensitive and specific marker of neuroendocrine neoplasms. The aims of this study were to determine whether INSM1 can be reliably used in cytology (Cellient) cell blocks, to ascertain whether staining correlates with paired surgical pathology specimens, and to compare its sensitivity and specificity with those of synaptophysin (SYN), chromogranin (CHR), and CD56 for neuroendocrine lung tumors. METHODS: Seventy-four primary lung neoplasms diagnosed on cytology were stained with INSM1, SYN, CHR, and CD56: 41 small cell lung carcinomas (SCLCs), 1 large cell neuroendocrine carcinoma (LCNEC), 10 carcinoid tumors, 11 adenocarcinomas, 9 squamous cell carcinomas, 1 mesothelioma and 1 poorly differentiated non-small cell lung carcinoma, not otherwise specified ...

Aim: Describe clinical and epidemiologic characteristics, stage, treatment and survival of patients with lung NET according to histological group -[typical carcinoid (TC), atypical carcinoid (AT), large cell neuroendocrine carcinoma (NEC). Methods: Retrospective longitudinal, multicenter study analyzing files of patients diagnosed with NET from 2005 to 2010. Small cell carcinoma was excluded. Comparisons among groups were done with X2. Survival curves were generated using Kaplan-Meier method. Results: 137 patients were included, mean age (SD) 59 (± 14) years; 71 (52%) male; 82 (60%) non-smokers. Histological classification: 54 TC, 49 NEC and 34 AC. Table below describes patients characteristics. Follow-up ranged from 1 to 78 months. Twenty seven patients (20%) died, 1 in TC, 2 in AC, 23 in NEC. The median overall survival (OS) calculated for NEC was 42 months, for other patients median ...
ABSTRACT. Background: We reported our experience with thymic carcinomas and review their clinical features, treatment strategies, and prognoses. Methods: From April 1998 to November 2012, 11 patients pathologically diagnosed with thymic carcinoma and treated in our hospital were investigated. Results: There were 7 men and 4 women, with a median age of 62 years (range, 35 - 72). According to the Masaoka staging system, 3 patients had stage II, 1 stage III disease, 3 stage IVa disease and 4 stage IVb disease. Ten patients had squamous cell carcinoma, whereas 1 had large cell neuroendocrine carcinoma (LCNEC). We performed surgery or multimodality therapy including surgery as the initial therapy for 8 patients. Of the non-surgical cases, 1 patient received chemoradiotherapy and survived for over 6 years without recurrence, whereas 2 received palliative care. Three of 4 patients who underwent complete resection survived without disease recurrence, whereas only 1 patient with LCNEC survived in the ...

Using enrichment analysis for Gene Ontology Biological Function we see that the genes/proteins with up-regulated PTMs and expression levels are associated with RNA processing, RNA splicing and, gene expression. Re-running the analysis for the sub-cluster of very highly regulated PTMS/genes (the large cluster in the middle) reveals enrichment for neuronal functions including: neuron projection, axon guidance, and neuron morphology. Enrichment for genes that are up-regulated in disease (using the Disease Perturbations from GEO Up library) shows enrichment for neuronal related cancers including: oligodendroglioma, multiple sclerosis, astrocytoma, and large cell neuroendocrine carcinoma. Finally, enrichment using the MGI Mammalian Phenotype library shows enrichment for genes that cause neuronal abnormalities in mice after knockdown including: abnormal neuron morphology, abnormal brain morphology, abnormal spinal cord morphology, and abnormal nervous system. Collectively, these results indicate that ...

This neoplasm is seen infiltrating the prostatic tissue in a solid/nested architectural pattern and the cells have a high nuclear to cytoplasmic ratio, with a distinctive basaloid appearance and areas of peripheral palisading. A prominent feature of this neoplasm is the presence of comedo-type necrosis in the central aspect of the nests, with discernible "ghost-cells". No cribriform growth pattern is identified. Based on these morphologic features, differential diagnostic considerations include a basal cell carcinoma of the prostate, poorly differentiated prostatic adenocarcinoma (Gleason pattern 5), poorly differentiated urothelial or squamous cell carcinoma as well as a high-grade neuroendocrine carcinoma. The morphology and CK7+/CK20- immunophenotype is compatible with a basal cell carcinoma and these tumors have been described to lack prostatic markers such as PSA/PSAP ...

The LNCaP cell line is a versatile and useful model that is suitable for the study of human prostate cancer in vitro. The elevation of LNCaP intracellular cAMP levels through the addition of membrane permeable cAMP analogues, phosphodiesterase inhibitors, adenylate cyclase activators, or components of the cAMP signal transduction pathway can induce reversible neuroendocrine differentiation. Elucidation of those genes that are differentially expressed between undifferentiated prostate cancer cells and prostate cancer cells that have been induced to differentiate may present new insights for the molecular mechanisms governing neuroendocrine differentiation, early detection of prostate cancer, and/or potential targets for gene therapy. In this study, differential display PCR was used to identify 226 differentially expressed PCR products. Twelve of the differential display PCR products were confirmed by Northern blot analysis and cloned. DNA sequencing and database comparisons were performed. Among ...

The spectrum of HPV-associated clinical findings in women ranges from genital warts to squamous intraepithelial neoplasia and invasive carcinoma (39) . HPV-16 and -18 are associated with intraepithelial and invasive lesions. HPV-16 is the most common type found in squamous carcinoma (40) , and HPV-18 is most common in adenocarcinomas and small cell neuroendocrine cervical carcinomas (41 , 42) . The association of virus infection with risk of development of cervical neoplasia has provided strong justification for devising immunization strategies against high-risk HPV types for therapy and prevention of progression and recurrence of invasive cervical cancer. We have performed one of the first multinational, multicenter studies of a genetically modified vaccinia-based vaccine. The study confirms that outpatient vaccination with TA-HPV is feasible, safe, and associated with little toxicity. Our results show that vaccination with TA-HPV is able to induce a measurable immune response in patients with ...
NEC of the breast is a rare disease. Only 6 case series have been reported in the literature, the largest comprising 74 cases [6-11]. With the 142 SEER cases reported here, this is the largest series reported to date and the first population study of mammary NEC.. The incidence of NEC of the breast has not been reported. Although NEC was estimated in 2003 to represent 2-5% of breast carcinomas [13], we found from our analysis of SEER data released in April 2012 that the incidence of mammary NEC is much lower. The age-adjusted incidence is 0.41 per 1 million-years in the female population of the U.S., and NEC comprises ,0.1% of all mammary carcinomas. Despite the low incidence of male breast carcinomas overall, the SEER data showed that NEC was proportionally more common in men than IMC-NOS (2.1% of all NEC; 0.8% of all IMC-NOS).. Because mammary NEC has not been well studied, its clinicopathologic features and outcome are poorly characterized. Among the 6 reported series studies, 2 studies with ...

Cancer clinical trial. Clinical trial for Avelumab Treatment in Patients With Neuroendocrine Carcinomas (NEC G3) Progressive After Chemotherapy.
BY Gauri R. Varadhachary, MD. Professor, GI Medical Oncology University of Texas MD Anderson Cancer Center. Background and Definition Carcinoma of unknown primary (CUP) is a diverse group of cancers and ranks within the top 10 cancer presentations. Broadly, CUP is defined as a biopsy-proven malignancy for which the anatomic origin remains unidentified (or undetermined) after adequate history and physical examination, laboratory studies, imaging, and pathologic evaluation. To further define the patient population, presentations that have histology and stage-specific therapy even in the absence of primary (melanoma, sarcoma, or lymphoma) are excluded as CUP cancers. The CUP clinical and research efforts concentrate on the vast majority of patients with common epithelial histologies such as adenocarcinoma, carcinoma, squamous carcinoma, and neuroendocrine carcinoma. The inability to identify a primary carcinoma tends to generate anxiety for the patient, who may feel that the evaluation is ...

Intracellular signaling pathways that regulate the production of lethal proteins in central neurons arent fully characterized. substrate GSK-3α/β (at Ser21/Ser9)(i.e. activation) and improved GSK-3α and GSK-3β kinase actions which occurred ahead of NP1 induction. Appearance of the dominant-negative inhibitor of Akt (Akt-kd) obstructed phosphorylation of GSK-3α/β and eventually improved NP1 induction. Whereas overexpression of constitutively turned on Akt (Akt-myr) or wild-type Akt (wtAkt) elevated GSK-α/β phosphorylation and attenuated NP1 induction. Transfection of neurons with GSK-3α siRNA blocked NP1 induction and cell loss of life completely. Similarly overexpression from the GSK-3β inhibitor Frat1 or the kinase mutant GSK-3βKilometres however not the wild-type GSK-3βWT obstructed NP1 induction and rescued neurons from loss of life. Our findings obviously implicate both GSK-3α and GSK-3β reliant system of NP1 induction and indicate a novel system in the legislation of ...
To examine the response to chronic high-dose angiotensin II (Ang II) and a proposed milder response in feminine hearts with respect to gene manifestation and ischemic injury. was recognized.
