Large cell neuroendocrine carcinoma (LCNEC) of the lung is a highly aggressive tumor without established standard treatment. The Hedgehog (Hh) signal, which is critical in embryogenesis, is known to play important roles in maintaining a malignant phenotype in various cancers. The present study explored the possibility of targeting the Hh signal in the treatment of LCNEC by suppressing Hh downstream molecules, Smoothened (Smo) and GLI family zinc finger 1/2 (Gli1/2), in 3 human LCNEC cell lines. Smo inhibitor, BMS-833923, and Gli inhibitor, GANT61, downregulated Gli1 and 2, resulting in the suppression of the cell viability of the 3 cell lines as assessed using an MTT assay...

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)...

A 15-year-old boy presented to us with a 4-month history of fever with worsening dyspnea since 1 month. His contrast-enhanced computed tomography scan of the thorax showed bilateral endobronchial lesions with complete collapse-consolidation of the left lung and partial collapse of the right lower lobe. His fiberoptic bronchoscopy guided biopsy had been reported in outside hospital as a neuroendocrine tumor. Due to worsening breathlessness, he had to be intubated. We repeated the endobronchial biopsy and combined with outside slides and blocks, was diagnosed to have an anaplastic lymphoma kinase-1 positive anaplastic large cell lymphoma (ALCL)...

Endobronchial obstruction is a known cause of an unexpandable lung. Endobronchial lesions are usually malignant, however benign cause like hemartoma, lipoma, amyloidosis and neuroendocrine tumors are known. We, hereby present the rare cause of bronchial elastosis presenting as right lower lobe lung collapse.

BACKGROUND: Twenty-seven percent of neuroendocrine tumors (NETs) are associated with distant metastases, and in some patients, the primary site is unknown. Orthopedia homeobox protein (OTP) has been described as a useful marker for lung carcinoids (LCs) and for separating low-grade typical carcinoids (TCs) from intermediate-grade atypical carcinoids (ACs) in resection specimens. This study evaluated OTP, thyroid transcription factor 1 (TTF-1), and Ki-67 expression in fine-needle aspiration (FNA) samples of various NETs...

Small cell lung cancer (SCLC) and large cell neuroendocrine carcinoma (LCNEC) of the lung are classified as variants of endocrine carcinoma and subdivided into pure or combined type. Clinical benefit of target therapy has not been established in these tumors. This study aimed to compare genetic and clinicopathological features between SCLC and LCNEC or pure and combined types, and explore the possibility of target therapy using next-generation sequencing. In 13 SCLC and 22 LCNEC cases, 72 point mutations, 19 deletions, and 3 insertions were detected...

Adenocarcinoma (AC) is the most common type of primary pulmonary malignancy. Lung carcinoid, however, is a rare neuroendocrine tumor. Their coexistence is extremely uncommon. We report the unique case of synchronous advanced lung AC of the right upper lobe (stage IIIB) and typical endobronchial carcinoid tumor in the contralateral lower lobe in a 49-year-old white female who had never smoked. PET-computed tomography scan revealed a fluorine-18-fluorodeoxyglucose-avid AC lesion, whereas the carcinoid tumor was fluorine-18-fluorodeoxyglucose occult...

Ewa Wojcik, Jan Kanty Kulpa
Lung cancer belongs to malignant tumors that possess the highest rates of morbidity and mortality in the world. A number of morphological, biological and clinical features justify the distinction of small-cell carcinoma with respect to the other histological types of lung cancer. The predominant neuroendocrine phenotype is critical for the selection of biomarkers used in diagnostics, monitoring and evaluation of treatment response; early onset relapses in patients with small-cell lung cancer (SCLC) and the evaluation of their prognosis...

Background: Typical and atypical carcinoids represent approximately 2% of all lung tumors. Survival of patients with typical bronchial carcinoids, unlike the survival of patients with most lung tumors, is generally long but dependent on stage. We report the findings of the Ochsner Medical Center/Louisiana State University (LSU) Health Sciences Center neuroendocrine tumor (NET) program. Methods: A database with all patients seen at the Ochsner Medical Center/LSU NET program was queried for patients with bronchopulmonary NET...

Long noncoding RNAs (lncRNAs) play crucial roles in carcinogenesis. Myocardial infarction-associated transcript (MIAT), originally isolated as a candidate gene for myocardial infarction, has been found to act as an oncogene in chronic lymphocytic leukaemias and neuroendocrine prostate cancer (NEPC); however, little is known about its expression pattern, biological function, and underlying mechanism in non-small cell lung cancer (NSCLC). In this study, we observed that MIAT expression was upregulated in NSCLC, and its overexpression was associated with advanced tumor stage...

Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is hyperplasia of noninvasive neuroendocrine cells originating from Kultchitsky cells. This is a rare pathological condition, suspected to be a precursor lesion of carcinoid, together with tumorlet. In the WHO histological classification (4th edition) revised in 2015, DIPNECH was added to the category that includes neuroendocrine tumors. Our patient was a 77-year-old woman who initially visited another doctor because of coughing. Chest CT revealed a mass occluding the right intermediate bronchial trunk, and bronchial carcinoid was suspected from biopsy findings, leading to referral of this patient to our department...

In this review, we outline the biology and management of patients with carcinosarcomas and related malignancies, which are often included under the broader concept of sarcomatoid carcinomas. Carcinosarcomas are unusual tumors that are commonly gynecologic in origin, where they are referred to as malignant mixed Müllerian tumors, but may appear in any anatomic site. Although a variety of hypotheses have been presented as to the biphasic nature of these tumors, carcinosarcomas seem to represent the best example in human cancers of the concept of epithelial-mesenchymal transition (EMT), in which the two parts of the tumor are genomically related to one another, as opposed to the mesenchymal component that represents a second neoplasm or (benign) reactive process...

CONTEXT: - Different testing algorithms and platforms for EGFR mutations and ALK rearrangements in advanced-stage lung adenocarcinoma exist. The multistep approach with single-gene assays has been challenged by more efficient next-generation sequencing (NGS) of a large number of gene alterations. The main criticism of the NGS approach is the detection of genomic alterations of uncertain significance. OBJECTIVE: - To determine the best testing algorithm for patients with lung cancer in our clinical practice...

BACKGROUND: Extrapulmonary neuroendocrine carcinomas (NECs) are poorly studied and are managed similar to lung NECs, which may not account for differences between the 2 groups of tumors as well as the heterogeneity within extrapulmonary NEC. METHODS: Data from the Surveillance, Epidemiology, and End Results program between 1973 and 2012 were used to estimate the relative percentages of lung NECs and subgroups of extrapulmonary NECs, epidemiological patterns at these sites, and the median and 5-year overall survival rates...

REVIEW
Lisa Bodei, Jarosław B Ćwikla, Mark Kidd, Irvin M Modlin
Bronchopulmonary (BP) neuroendocrine tumors (NETs) comprise a spectrum of tumors that develop from respiratory neuroendocrine cells and represent ~20% of all lung neoplasia and ~30% of all NETs. The only curative treatment is surgical resection. For well-differentiated forms (typical and atypical carcinoids), medical therapy ranges from bioactive agents (e.g., somatostatin analogs), to biotherapy (e.g., everolimus), standard chemotherapy and peptide receptor radionuclide therapy (PRRT). PRRT with radiolabeled somatostatin analogs is an innovative treatment for inoperable or metastasized, well/moderately differentiated, NET...
