Lung neuroendocrine tumors comprise 20% of all pulmonary tumors. Their appearance and behavior are very heterogeneous. Histologically they are divided into four groups, well-differentiated and low-malignant typical carcinoid, poorly differentiated and worse prognosis atypical carcinoid, and highly malignant small cell neuroendocrine carcinoma and large cell neuroendocrine carcinoma. Of these, the most common is small cell lung cancer with an incidence of 15%, while those of large cell neuroendocrine tumors and lung carcinoids are 3% and 2%, respectively...

Neuroendocrine tumors (NETs) are aggressive diseases developing from neuroendocrine cells that most frequently involve the gastro-entero-pancreatic tract and the lung, but more rarely are found in almost all body tissues. Limited biological and clinical data are currently available for NETs in uncommon sites, such as female genital tract. NETs represent 0.9% to 1.5% of the tumors of the uterine cervix. This case is reported on a 75-year-old Caucasian woman, presenting with dental and generalized pain for two weeks...

PURPOSE: In isolated adrenocorticoropic hormone (ACTH) deficiency (IAD), autoimmunity against corticotrophs has been suggested; however, the pathogenesis remains largely unknown. Large cell neuroendocrine carcinoma (LCNEC) of the lung is a pulmonary tumor of high-grade malignant neuroendocrine tumor and it reportedly caused paraneoplastic syndrome by autoimmunity in several cases. METHODS: A 42-year-old woman with isolated adrenocorticotropic (ACTH) hormone deficiency (IAD) was diagnosed with large cell neuroendocrine carcinoma (LCNEC) 3 years after being diagnosed with IAD...

Amphicrine carcinoma is a distinct type of carcinoma characterized by synchronous exocrine and endocrine differentiation within the same tumor cell. Such tumors are exceedingly rare and most commonly recognized in the gastrointestinal tract. In the lung, sporadic descriptions of such lesions exist. This report presents 3 more such tumors, expanding the spectrum of amphicrine carcinomas in this organ. The patients were 3 men, 53 to 78 years of age (mean: 63 y) and all were current or former smokers. In one patient the tumor was an incidental finding, the others presented with lower respiratory symptoms...

OBJECTIVE: Idiopathic pulmonary fibrosis (IPF) is associated with an increased incidence of lung cancer, but patients with IPF often have poor pulmonary function and are vulnerable to pneumothorax and so using an invasive procedure to diagnose a single nodule detected on chest CT risks a critical adverse outcome. 18 F-fluorodeoxyglucose (18 F-FDG) positron emission tomography/computed tomography (PET/CT) is recognized to be useful for differentiating between benign and malignant solitary pulmonary nodules (SPN) in patients without IPF, but its diagnostic accuracy has not been investigated in patients with IPF...

BACKGROUND: The response to temozolomide (TMZ) treatment in small-cell lung cancer (SCLC) correlated with O(6)-methylguanine -DNA methyltransferase (MGMT) promoter methylation. 1p/19q co-deletion within oligodendroglioma is a responsive predictor for TMZ. Currently, the status of MGMT promoter methylation and 1p/19q co-deletion in pulmonary carcinoid (PC) and large-cell neuroendocrine carcinoma (LCNEC) is not reported. METHODS: Nine PC [two atypical carcinoids (AC), seven typical carcinoids (TC)] and six LCNEC patients were collected retrospectively...

CONTEXT: - Air space invasion or aerogenous spread of lung adenocarcinoma is a relatively new concept and has been implicated as a potential prognostic factor as well as has been added as an exclusion point in the diagnosis of minimally invasive adenocarcinoma. Potential role for Ki-67 immunostaining as a diagnostic and prognostic marker in pulmonary carcinoid tumors has been suggested in the literature, given the significant interobserver variability and the difficulty in predicting their clinical behavior...

Fetal adenocarcinoma is a rare variant of lung adenocarcinoma, which is subcategorized into low-grade and high-grade forms. High-grade fetal adenocarcinoma confers worse prognosis than low-grade fetal adenocarcinoma, but the prognostic differences between high-grade fetal adenocarcinoma and conventional lung adenocarcinoma are unknown. We reviewed tissue sections of 3719 cases of surgically resected primary lung cancers and found 53 lung cancers with a high-grade fetal adenocarcinoma component. We analyzed their clinicopathological and immunohistochemical features, and performed a prognostic analysis of adenocarcinomas with the fetal-type component...

Abnormal expressions of extracellular matrix (ECM) proteins are correlated with increased tumor progression, an advanced histologic grade, and metastasis. LCN1 cells derived from a pulmonary large cell neuroendocrine carcinoma were grown to form an Aegagropila-shaped conglomeration on a suspension culture dish (LCN1-sus). In contrast, LCN1 cells cultured in a type I collagen dish were adherent and tended to grow as spindle-shaped individual cells (LCN1-co). In this study, aiming at the discovery of predictive markers for tumor invasion, we performed protein profiling between LCN1-sus and LCN1-co cells using two-dimensional gel electrophoresis...

Pulmonary large-cell neuroendocrine carcinomas (LCNECs) have similarities with other lung cancers, but their precise relationship has remained unclear. Here we perform a comprehensive genomic (n = 60) and transcriptomic (n = 69) analysis of 75 LCNECs and identify two molecular subgroups: "type I LCNECs" with bi-allelic TP53 and STK11/KEAP1 alterations (37%), and "type II LCNECs" enriched for bi-allelic inactivation of TP53 and RB1 (42%). Despite sharing genomic alterations with adenocarcinomas and squamous cell carcinomas, no transcriptional relationship was found; instead LCNECs form distinct transcriptional subgroups with closest similarity to SCLC...

Primary lung neuroendocrine tumors (NETs) consist of typical and atypical carcinoids, large-cell neuroendocrine carcinomas and small-cell lung carcinomas. NETs are highly heterogeneous in histological characteristics, clinical presentation and natural history. While there are morphological and immunohistochemical criteria to establish diagnosis, there is a lack of universal consensus for prognostic factors or therapeutic targets for personalized treatment of the disease. Thus, identifying potential markers of neuroendocrine differentiation and prognostic factors remains of high importance...

Carcinoids and large cell neuroendocrine carcinomas (LCNECs) are rare neuroendocrine lung tumors. Here we provide an overview of the most updated data on the molecular characteristics of these diseases. Recent genomic studies showed that carcinoids generally contain a low mutational burden and few recurrently mutated genes. Most of the reported mutations occur in chromatin-remodeling genes (e.g., menin 1 gene [MEN1]), and few affect genes of the phosphoinositide 3-kinase (PI3K)-AKT-mechanistic target of rapamycin gene pathway...

BACKGROUND: Pulmonary large cell neuroendocrine carcinoma (LCNEC) represents a rare entity in lung cancer with dismal prognosis. In the present study, we investigated whether there are significant differences between central and peripheral tumors of LCNEC, in terms of clinicopathologic features, genomic profiles, and survival. METHODS AND MATERIALS: A total of 126 cases of LCNEC were included. The tumors with invasion of the segmental and/or lobar bronchus were classified as central LCNEC and those without as peripheral LCNEC...

INTRODUCTION: The immune microenvironment of high-grade neuroendocrine carcinoma of the lung, including programmed death ligand 1 (PD-L1) expression, has not been well characterized. METHODS: On the basis of immunohistochemistry (IHC) results, PD-L1 expression on tumor cells (TCs) and tumor-infiltrating immune cells (ICs) was scored as follows: TC0 and IC0 were defined as PD-L1 expression less than 1%, TC1 and IC1 as at least 1% but less than 10%, TC2 and IC2 as 10% or more but less than 50%, and TC3 and IC3 as 50% or more...

In the light of novel cancer immune therapies, the status of antitumor inflammatory response and its regulation has gained much attention in patients with lung cancer. Ample datasets exist for non-small-cell lung cancer, but those for pulmonary neuroendocrine tumors are scarce and controversial. Here, tumor-associated inflammation, CD8+ cell infiltration and PD-L1 status were evaluated in a cohort of 57 resected carcinoids and 185 resected neuroendocrine carcinomas of the lung (58 large cell carcinomas and 127 small cell carcinomas)...

Neuroendocrine tumours of the lung comprise low [typical carcinoid (TC)], intermediate [atypical carcinoid (AC)] and high-grade [small-cell lung cancer (SCLC) and large-cell neuroendocrine carcinoma (LCNEC)] malignancies, while a pre-invasive lesion [diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH)] may generate a subset of peripheral carcinoid tumours. These neoplasms are differentiated conventionally based on mitotic rate, presence of necrosis and cytological details, according to the 2015 World Health Organisation (WHO) classification...
