The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

The human c-erbB-1 gene is located in the chromosomal region 7p14 and 7p12.
A condition of lung damage that is characterized by bilateral pulmonary infiltrates (PULMONARY EDEMA) rich in NEUTROPHILS, and in the absence of clinical HEART FAILURE. This can represent a spectrum of pulmonary lesions, endothelial and epithelial, due to numerous factors (physical, chemical, or biological).
Study of intracellular distribution of chemicals, reaction sites, enzymes, etc., by means of staining reactions, radioactive isotope uptake, selective metal distribution in electron microscopy, or other methods.
A tumor derived from mesothelial tissue (peritoneum, pleura, pericardium). It appears as broad sheets of cells, with some regions containing spindle-shaped, sarcoma-like cells and other regions showing adenomatous patterns. Pleural mesotheliomas have been linked to exposure to asbestos. (Dorland, 27th ed)

Bronchioloalveolar carcinoma with metastasis to the pituitary gland: a case report. (1/293)

An unusual case of metastatic bronchioloalveolar carcinoma of the lung presented as a pituitary tumour in a young adult Chinese female, who subsequently died after having undergone trans-sphenoidal resection. Metastatic cancers of the pituitary are uncommon even in necropsy series and rarely give rise to clinical symptoms. This case draws attention to the fact that, although uncommon, pituitary metastases have been noted with increasing frequency and their distinction from primary pituitary tumours is often difficult. A metastatic pituitary tumour may be the initial presentation of an unknown primary malignancy, wherein the metastatic deposits may also be limited to the pituitary gland. Clinicians and pathologists alike should consider a metastatic lesion in the differential diagnosis of a non-functioning pituitary tumour.  (+info)

Recurrence of bronchioloalveolar carcinoma in transplanted lungs. (2/293)

BACKGROUND: Bronchioloalveolar carcinoma is a distinctive subtype of typical adenocarcinoma of the lung that tends to metastasize widely throughout the lungs but less commonly elsewhere. Because conventional therapies for intrapulmonary metastatic bronchioloalveolar carcinoma are generally ineffective, we treated seven patients who had intrapulmonary metastatic bronchioloalveolar carcinoma with lung transplantation. METHODS: Seven patients with biopsy-proved bronchioloalveolar carcinoma and no evidence of extrapulmonary disease received transplants of either one or two cadaveric lungs. At transplantation, all native lung tissue was removed and replaced with a donor lung or lungs. The patients received the usual post-transplantation care given at the institution. RESULTS: Four of the seven patients had recurrent bronchioloalveolar carcinoma within the donor lungs; the recurrences appeared from 10 to 48 months after transplantation. All recurrences were limited to the donor lungs. Histologic and molecular analyses showed that the recurrent tumors in three patients originated from the recipients of the transplants. CONCLUSIONS: Lung transplantation for bronchioloalveolar carcinoma is technically feasible, but recurrence of the original tumor within the donor lungs up to four years after transplantation was common.  (+info)

Alpha1-antitrypsin deficiency allele carriers among lung cancer patients. (3/293)

Lung cancer (LC) and chronic obstructive pulmonary lung diseases (COPDs; including emphysema and chronic bronchitis) share a common etiology. Despite the known associations of alpha1-antitrypsin deficiency (alpha1AD) with COPD and COPD with LC, few studies examined the association of alpha1AD alleles and LC. We hypothesize that heterozygous individuals who carry a deficient allele of the alpha1AD gene Pi (protease inhibitor locus) are at an increased risk of developing LC. The Pi locus is highly polymorphic with >70 variants reported. There are at least 10 alleles associated with deficiency in alpha1-antitrypsin. Using an exact binomial test, we compared the alpha1AD carrier rate in 260 newly diagnosed Mayo Clinic LC patients to the reported carrier rate in Caucasians in the United States (7%). alpha1AD carrier status, determined by isoelectric focusing assay, was examined with respect to the history of cigarette smoking, COPD, and histological types. Thirty-two of the 260 patients (12.3%; 95% confidence interval, 8.6-16.9%) carried an alpha1AD allele, which was significantly higher than expected (P = 0.002). Twenty-four of the 32 carriers had allele S, 6 had allele Z, and 2 had allele I. Patients who never smoked cigarettes were three times more likely to carry a deficient allele (20.6%; P = 0.008), although smokers had a higher carrier rate (11.1%; P = 0.025) when compared with the 7% rate. Patients with squamous cell or bronchoalveolar carcinoma had a significantly higher carrier rate than expected (15.9% and 23.8%, P < or = 0.01, respectively). Our preliminary findings suggest that individuals who carry an alpha1AD allele may have an increased risk for developing LC, specifically squamous cell or bronchoalveolar carcinoma.  (+info)

Telomerase activity as a prognostic indicator in stage I non-small cell lung cancer. (4/293)

Patients with stage I non-small cell lung cancer (NSCLC) are typically treated with surgical resection alone. However, about one-third of such patients develop disease recurrence and die within 5 years after complete resection. The ability to predict recurrence could represent an important contribution to treatment planning. This study evaluates the presence of telomerase activity in tumor cells as a predictor of disease recurrence and cancer-related death after operation for stage I NSCLC patients. The activity of the telomerase enzyme was investigated by telomeric repeat amplification protocol (TRAP) in tumors and matching normal lung tissue samples obtained from 107 consecutive operable patients with pathological stage I NSCLC. Telomerase activity was detected in 66 (62%) of the 107 tumors examined and in none of the corresponding adjacent noncancerous lung tissue samples. Correlation with pathological parameters showed that telomerase activity was associated with histopathological grade (P = 0.0135) but not with tumor size or histological type. Univariate survival curves, estimated using the method of Kaplan and Meier, defined a significant association between telomerase activity and both disease-free survival (P = 0.0115) and overall survival (P = 0.0129). In multivariate analyses, performed by Cox's proportional hazards regression models, the presence of telomerase activity was the only strong predictor of disease-free survival (P = 0.0173) and overall survival (P = 0.0187). Our data indicate that telomerase activity can be an important prognostic factor that should be considered in future prospective trials of adjuvant therapy for high-risk stage I NSCLC patients.  (+info)

Prognostic implications of calbindin-D28k expression in lung cancer: analysis of 452 cases. (5/293)

Calbindin D28k (Ca-D28k) acts as a buffering system to maintain cellular calcium homeostasis and is thought to play a role in inhibiting apoptosis. The goals of this study were to assess CA-D28k expression in lung carcinomas and to correlate these results with patient survival. A total of 452 lung carcinomas were immunostained with a monoclonal antibody specific for Ca-D28K using an avidin-biotin peroxidase technique. The number of cells with nuclear staining was graded semiquantitatively into one of five groups: 0, fewer than 10%, 10 to 25%, more than 25 to 50%, more than 50 to 75%, and more than 75%. Results were correlated with patient survival using Kaplan-Meier survival curves. A total of 335 of 452 (74%) lung carcinomas were positive for Ca-D28k. There was no statistically significant difference in the prevalence of Ca-D28k expression in tumors of different histologic type. Kaplan-Meier survival analysis revealed that for patients with adenocarcinoma, those with Ca-D28k-positive tumors had a better overall survival than patients with Ca-D28k-negative tumors (P = .036). This difference was also significant for patients with Stages I and II adenocarcinomas (P = .033). No statistically significant difference in prognosis was observed for patients with Stages III and IV adenocarcinomas or for patients with other lung carcinoma types of varying stage. Ca-D28k is commonly expressed in lung carcinomas of all histologic types. For patients with localized adenocarcinoma of the lung, Ca-D28k expression correlated with improved survival. No correlation between Ca-D28k expression and patient survival was found for disseminated adenocarcinoma and for other histologic types of lung carcinoma.  (+info)

Evidence for a protein related immunologically to the jaagsiekte sheep retrovirus in some human lung tumours. (6/293)

Human bronchioloalveolar carcinoma (BAC) is a lung cancer, morphologically similar to an endemic contagious lung neoplasm of sheep called sheep pulmonary adenomatosis (SPA) or jaagsiekte. SPA is caused by an exogenous type B/D retrovirus (jaagsiekte sheep retrovirus (JSRV)), which prompted the present study to obtain evidence of a retrovirus in BAC. A panel of 249 human lung tumours, 21 nontumour lung lesions, four normal lung tissues, 23 adenocarcinomas from other organs and a cell line expressing a human endogenous retrovirus protein was examined immunohistochemically using a rabbit antiserum directed against the JSRV capsid protein. Specific staining was detected only in the cytoplasm of recognizably neoplastic cells in the pulmonary alveoli of 39 of 129 (30%) BACs, 17 of 65 (26%) lung adenocarcinomas and two of seven large cell carcinomas. The remaining samples were negative. These results support the hypothesis that some human pulmonary tumours may be associated with a jaagsiekte sheep retrovirus-related retrovirus, warranting further studies.  (+info)

IL-1beta induces eotaxin gene transcription in A549 airway epithelial cells through NF-kappaB. (7/293)

Eotaxin is an asthma-related C-C chemokine that is produced in response to interleukin-1beta (IL-1beta). We detected an increase in newly transcribed eotaxin mRNA in IL-1beta-stimulated airway epithelial cells. Transient transfection assays using promoter-reporter constructs identified a region as essential for IL-1beta-induced increases in eotaxin transcription. Using site-directed mutagenesis, we found that a nuclear factor-kappaB (NF-kappaB) site located 46 bp upstream from the transcriptional start site was both necessary and sufficient for IL-1beta induction of reporter construct activity. Electrophoretic mobility shift assay demonstrated that IL-1beta-stimulated airway epithelial cells produced p50 and p65 protein that bound this site in a sequence-specific manner. The functional importance of the NF-kappaB site was demonstrated by coexpression experiments in which increasing doses of p65 expression vector were directly associated with reporter activity exclusively in constructs with an intact NF-kappaB site (r(2) = 0.97, P = 0.002). Moreover, IL-1beta-induced increases in eotaxin mRNA expression are inhibited by inhibitors of NF-kappaB. Our findings implicate NF-kappaB and its binding sequence in IL-1beta-induced transcriptional activation of the eotaxin gene.  (+info)

Temporal/spatial expression of nuclear receptor coactivators in the mouse lung. (8/293)

Our laboratory has previously demonstrated that retinoic acid nuclear receptor, thyroid transcription factor-1 (TTF-1), and nuclear receptor coactivators such as cAMP response element binding protein (CREB) binding protein (CBP)/p300 and steroid receptor coactivator-1 (SRC-1) form an enhanceosome on the 5'-enhancer region of the human surfactant protein B gene. Immunohistochemistry was used to identify cells that coexpressed CBP/p300, SRC-1, retinoid X receptor, and TTF-1 in the developing and mature lung. CBP/p300 and SRC-1 were expressed in the adult mouse lung, CBP and p300 being present in both alveolar type I and type II epithelial cells and SRC-1 and TTF-1 being restricted to type II epithelial cells. CBP/p300, SRC-1, and TTF-1 were readily detected in the nuclei of developing respiratory epithelial tubules in fetal mice from embryonic days 10 to 18. CBP/p300 and SRC-1 were also detected in developing mesenchymal cells. These coactivators were coexpressed with TTF-1 and SP-B in human pulmonary adenocarcinoma cells (H441 cells) in vitro. Interaction assays with a two-hybrid reporter analysis demonstrated direct interactions among TTF-1, SRC-1, and CBP/p300 in H441 cells. These findings support a role for retinoic acid receptor and nuclear receptor coactivators in the regulation of SP-B gene expression in the respiratory epithelium.  (+info)

AU - Park, Choong Ki. AU - Primack, Steven L.. PY - 1997/1/1. Y1 - 1997/1/1. N2 - Bronchioloalveolar carcinoma is characterized pathologically by a pulmonary neoplasm showing lepidic growth. More than half of all patients with bronchioloalveolar carcinoma are asymptomatic. The most frequent symptoms and signs are cough, sputum, shortness of breath, weight loss, hemoptysis, and fever. Bronchorrhea is unusual and a late manifestation. Nonmucinous bronchioloalveolar carcinoma tends to be more localized and has a lower frequency of bronchogenic spread than mucinous bronchioloalveolar carcinoma. Bronchioloalveolar carcinoma appears radiographically as a single nodule, segmental or lobar consolidation, or diffuse nodules. At computed tomography (CT), the single nodular form appears as a peripheral nodule or localized ...

Both atypical adenomatous hyperplasia (AAH) and bronchioloalveolar carcinoma (BAC) appear as ground glass opacity (GGO) lesions by computed tomography (CT) and are sometimes difficult to differentiate. To aid distinction between the two, we examined their CT number histograms. Methods. Histograms of pixel CT numbers were made for AAH (n = 9) and nonmucinous BAC (n = 8), and the peak and mean CT numbers on the histogram were quantified. Results. Although there was no significant difference in lesion size between AAH and BAC, all AAHs were less than or equal to 1 cm in diameter. All AAHs and BACs manifested one histogram peak. Both the peak and mean CT numbers on the histogram were significantly lower for AAH ...

The coexistence of interstitial pulmonary fibrosis and alveolar cell carcinoma is well known. The familial occurrence of a combination of these two entities, however, is very rare. We present a family of which five members had diffuse interstitial pulmonary fibrosis. Three of them had in addition alveolar cell carcinoma. In a sixth family member, evidence of alveolar cell carcinoma was present without proven interstitial fibrosis. An autosomal dominant trait is suggested as the mode of inheritance of both interstitial fibrosis and alveolar cell carcinoma in this family.. ...

In this issue of Oncology, Levy and colleagues provide a comprehensive review of bronchioloalveolar carcinoma [BAC], with a focus on the management of this rare disease, which represents 4% of all lung cancers.[1] The definition of BAC was revised by the World Health Organization (WHO) in 2004, with changes made to the diagnostic criteria and classification.[2] BAC was defined as an adenocarcinoma of the lung that grows in a lepidic fashion along the alveolar septa without invasion of stroma, blood vessels, or pleura. BAC has been sub-classified into three types: nonmucinous, mucinous, and mixed. 1

inhibitor, just about everyone who responds eventually has the cancer become resistant.. Every treatment is likely to have some side effects, and some can be serious. She may go a very, very long time without it affecting her quality of life or survival. The key question I think needs to be asked is not should we do nothing or do something?, but rather, do you want to blow your best options while shes feeling fine and potentially without symptoms for years, or do you want to save your treatments for when you need them? Its not now or never, but now or later. And how bad would it be if she went on a treatment and had a serious or fatal complication? Fortunately, thats not likely, but its possible to have permanent problems or even die from chemo or tarceva or avastin complications. Its tremendously unfortunate if it happens, but if its a setting of facing an imminent disease-induced problem, thats less of a travesty than if were treating a scan rather than the person..

Estrogen has been indicated to play an etiological role in the development of lung adenocarcinoma (ADC), particularly bronchioloalveolar carcinoma (BAC), a type of ADC that develops from a benign adenomatous lesion, atypical adenomatous hyperplasia (AAH). Polymorphisms in the CYP19A1 gene cause interindividual differences in estrogen levels. Here, 13 CYP19A1 single-nucleotide polymorphisms (SNPs) were examined for associations with lung AAH risk. AAH is detected as ground-glass opacity (GGO) by computed tomography (CT) examination, and this study consisted of 100 individuals diagnosed with GGO in their lungs among 3088 CT-based cancer screening examinees and 424 without. Minor allele carriers for the rs3764221 SNP showed an elevated risk for GGO [odds ratio (OR) = 1.72, P = 0.017]. Associations of this SNP with risks for lung AAH and BAC in the lungs were next examined using 359 ADC cases whose resected lung lobes were subjected to a histological examination for AAH accompaniment and the ...
No previous study has investigated neutral large amino acid transporter type 1 (LAT1) in normal lung cells, or in atypical adenomatous hyperplasia(s) (AAH) and nonmucinous bronchioloalveolar carcinoma(s) (NMBAC) of the lung. The authors examined: (1) the levels of LAT1 mRNA/glyceraldehyde-3-phosphate dehydrogenase (GAPDH) mRNA in 41 normal lung tissues and 34 NMBAC using semiquantitative reverse transcription-polymerase chain reaction; (2) LAT1 mRNA and protein expressions in 35 normal lung tissues, 34 AAH (11 lesions were interpreted as low-grade AAH and 23 as high-grade AAH), and 43 NMBAC using in situ hybridization and immunohistochemistry; and (2) the association of the incidences of LAT1 mRNA and protein expressions with cell proliferation in these lesions. The level of LAT1 mRNA/GAPDH mRNA (1) tended to be higher in NMBAC (12.0+/-8.1) than in normal lung tissues (1.0+/-0.2), and (2) covered a much wider range (from 0 to 276) in NMBAC than in normal lung tissues (from 0 to 5.8), with six ...

Noguchi et al.10 analyzed the histology of small lung adenocarcinoma and classified it according to the presence or absence of BAC components and other histologic characteristics. This seminal study brought to attention the importance of BAC and its association with excellent prognosis, including 100% 5-year survival. Subsequent studies11-16 elucidated various histologic features of prognostic significance in lung adenocarcinomas with BAC components, including size of scar, percentage of lepidic growth, percentage of papillary growth, vascular invasion, and size or pattern of invasion. Based on these studies, new concepts were introduced, such as including the subgroups of AIS and MIA, according to the new IASLC/ATS/ERS classification system.. In accordance with earlier studies, our results suggested better tumor behavior in MIA (≤5 mm) compared to SAD, which supports distinguishing these classes of tumors from stage T1a cancers. In this study, MIA outcomes were excellent with no lymph node ...

Vandetanib (ZactimaTM) is a novel, orally available inhibitor of both vascular endothelial growth factor receptor-2 (VEGFR-2) and epidermal growth factor receptor (EGFR) tyrosine kinase. In the present study, a line of transgenic mice with a mouse Egfr gene mutation (delE748-A752) corresponding to a human EGFR mutation (delE746-A750) was established. The transgenic mice developed atypical adenomatous hyperplasia to adenocarcinoma of the lung at around 5 weeks of age and died of lung tumors at approximately 17 weeks of age. In the mice treated with vandetanib (6mg/kg/day), these lung tumors disappeared and the phosphorylations of EGFR and VEGFR-2 were reduced in lung tissues to levels comparable to those of non-transgenic control mice. The median overall survival time of the transgenic mice was 28 weeks in the vandetanib-treated group and 17 weeks in the vehicle-treated group. Vandetanib significantly prolonged the survival of the transgenic mice (log-rank test, p<0.01); resistance to ...

With the increase in the number of lung transplants, it is expected that there will be a corresponding increase in the number of lung cancers reported in these patients. Longevity of the transplant recipients, lung transplantation for chronic obstructive pulmonary disease and idiopathic pulmonary fibrosis, a history of smoking, and the increasing age of the lung donors make lung cancer more likely. Nodules and masses seen in chest imaging in lung transplant patients call for work up until a final diagnosis is achieved because there is a high likelihood of a serious infection or malignancy. The presence of a native lung is a major risk factor for lung cancer occurring in the transplant setting. Lung cancer of donor origin is rare. Bronchioloalveolar carcinoma confined to one lung can potentially be treated by transplanting the affected lung. Treatment for patients with lung cancer in the lung transplant setting has to be individualized because of the complexity of their medical problems and ...
The homogeneous, pink, mucinous alveolar exudate of bronchioloalveolar carcinoma is also PASD-positive. It is not foamy as in pneumocystis pneumonia or granular as in alveolar proteinosis. It stains with alcian blue, whereas the others do not. In this photo, not all of the alveoli are lined by tumor. The tumor cells (arrows) should not be mistaken for hyperplastic type II cells. Protein-rich pulmonary edema fluid can have a similar appearance but is PASD-negative.. Pulmonary alveolar proteinosis--PAS stain ...
Vandetanib (ZactimaTM) is a novel, orally available inhibitor of both vascular endothelial growth factor receptor-2 (VEGFR-2) and epidermal growth factor receptor (EGFR) tyrosine kinase. In the present study, a line of transgenic mice with a mouse Egfr gene mutation (delE748-A752) corresponding to a human EGFR mutation (delE746-A750) was established. The transgenic mice developed atypical adenomatous hyperplasia to adenocarcinoma of the lung at around 5 weeks of age and died of lung tumors at approximately 17 weeks of age. In the mice treated with vandetanib (6mg/kg/day), these lung tumors disappeared and the phosphorylations of EGFR and VEGFR-2 were reduced in lung tissues to levels comparable to those of non-transgenic control mice. The median overall survival time of the transgenic mice was 28 weeks in the vandetanib-treated group and 17 weeks in the vehicle-treated group. Vandetanib significantly prolonged the survival of the transgenic mice (log-rank test, p<0.01); resistance to ...
HGF was detected in BALF supernatants from nearly all of the patients with BAC and was related to local production, because fresh alveolar cells, recovered by BAL and cultured for 24 h, expressed HGF mRNA and released significant amounts of HGF protein. By contrast, HGF was never detected in BALF supernatants from healthy controls, whose alveolar cells did not express HGF mRNA or release HGF protein. Initial studies showed that HGF is a stromal-derived factor affecting the proliferation and motility of normal and tumoral epithelial cells, especially in NSCLC (24) . It was also shown that tumor cells were a potential source of HGF in NSCLC (25, 26, 27, 28) . We show, for the first time, that tumor-infiltrating neutrophils are a potential source of HGF in patients with BAC-subtype ADC. Indeed, HGF levels in BALF supernatants correlated with neutrophil numbers in alveolar spaces but not with counts of other inflammatory cells (lymphocytes and macrophages). Second, immunostaining of BALF cytospin ...

VGA is a rare subtype of cervical adenocarcinoma first described by Young and Scully,2 which has been reported to have a more favorable prognosis compared to conventional adenocarcinomas.1 It is characterized by numerous papillary villous structures which are lined by epithelial cells with only mild cytologic atypia. The epithelial cells may be mucinous or non-mucinous, and the central fibrovascular cores of the papillae usually have variable number of inflammatory cells. Associations between VGA and HPV and oral contraceptives have been reported.3,5,7,13,14. The diagnosis of VGA has been demonstrated to be rather challenging on cytology as the cytologic features may be deceptively bland-looking, resulting in its misdiagnosis as reactive glandular cells. Indeed, the initial cytologic impression in one of our three cases was a reactive lesion and the neoplastic cell clusters could have been overlooked if it had not been for the simultaneous punch biopsy specimen that harbored a VGA. There are ...
Lung adenocarcinomas are malignant glandular neoplasms can be well to poorly differentiated. In well differentiated tumors, glands are lined by columnar or mucinous epithelium with basally oriented nuclei containing prominent nucleoli. There frequent mitotic figures. In poorly differentiated adenocarcinomas, the only clue to their glandular nature may be the presence of intracytoplastic mucin, as they form solid sheets. Variants of adenocarcinoma, according to the WHO schema, include bronchioloalveolar, mucinous and papillary (Fletcher). ...

Introduction: Adenocarcinoma is the most common histologic type of lung cancer. To address advances in oncology, molecular biology, pathology, radiology, and surgery of lung adenocarcinoma, an international multidisciplinary classification was sponsored by the International Association for the Study of Lung Cancer, American Thoracic Society, and European Respiratory Society. This new adenocarcinoma classification is needed to provide uniform terminology and diagnostic criteria, especially for bronchioloalveolar carcinoma (BAC), the overall approach to small nonresection cancer specimens, and for multidisciplinary strategic management of tissue for molecular and immunohistochemical studies. Methods: An international core panel of experts representing all three societies was formed with oncologists/pulmonologists, pathologists, radiologists, molecular biologists, and thoracic surgeons. A systematic review was performed under the guidance of the American Thoracic Society Documents Development and ...

Persistent GGO are usually classified as adenocarcinomas, ranging from premalignant lesions (atypical adenomatous hyperplasia) to invasive disease. They are generally slow-growing lesions. Because their significance can be difficult to determine, optimal follow-up and management are not clearly known. The prognosis of these lesions is driven by their histologic characteristics, which are available only after surgical resection.. The Mayo Clinic team tackling the uncertainties of GGOs includes biomedical imaging engineers, pathologists, pulmonologists and radiologists. They are developing CANARY as a noninvasive quantitative imaging tool designed to differentially categorize CT-detected peripheral subsolid lung nodules and predict underlying pathology and prognosis. Preliminary data suggest that CANARY, utilizing volumetric histogram density analysis (so-called radiologic biopsies), effectively risk-stratifies these nodules.. To further validate this technology, CANARY researchers are using data ...
Cellular atypia in rodent lungs is characterized by one or more of the following features: cytoplasmic basophilia, hyperchromatic nuclei, loss of nuclear polarity, high nuclear to cytoplasmic ratio, karyomegaly, anisokaryosis, and pleomorphism. The atypical cells are often poorly differentiated and may be binucleated. They may have multiple and/or enlarged nucleoli. In the pathology literature, cellular atypia, atypical hyperplasia, and atypical adenomatous hyperplasia have been used synonymously with dysplasia to signify cells and nuclei with abnormal size, shape, organization, and/or tinctoral properties. While individual cells in the alveoli may have features of atypia, cellular atypia can also be seen in areas of bronchial, bronchiolar, or alveolar epithelial hyperplasia or squamous metaplasia. Some of the features listed above may also be seen in regenerating cells (e.g., cytomegaly, karyomegaly, cytoplasmic basophilia, increased nuclear to cytoplasmic ratio). The biological significance of ...
Nectin-like molecule-5 (Necl-5) is an immunoglobulin (Ig)-like molecule that is up-regulated in many types of cancer cells. It was shown experimentally that Necl-5 enhances cell migration, proliferation, and metastasis, but its clinical significance has not been documented. The aim of this study was to observe the expression of Necl-5 in surgically resected primary lung adenocarcinomas and to investigate its clinical significance. A total of 63 surgically resected primary pulmonary adenocarcinoma tissues were investigated by immunohistochemistry for the expression of Necl-5. The relationship between expression of Necl-5 and clinicopathological features was analyzed, and the influence of Necl-5 expression on outcomes in these patients was assessed. A strong expression of Necl-5 by cancer cells was observed in 43 of the 63 tumors. The overexpression of Necl-5 by cancer cells was significantly associated with lymph node metastasis (P = 0.0398), TNM staging (P = 0.0367), and the bronchioloalveolar ...

With the genetic sample method, the GGO will in a clever way select parameter permutations and the GGO modified strategy will export complete trading history for each permutation so that the GWFO can afterwards perform a walk-forward analysis on those trading history files. (Select menu option Recalculate, Genetic Sample Walk-forward) Thus with this approach, all walk-forward calculations takes place within the GWFO stand-alone software. Since the GWFO stand-alone executes much faster than the EL interpreter, the Genetic sample walk-forward method is much faster than the Concurrent method ...

Epstein-Barr virus (EBV) is a ubiquitous herpesvirus, and most people have serological evidence of previous viral infection at adult age. EBV is associated with infectious mononucleosis and human cancers, including some lymphomas and gastric carcinomas. Although EBV was first reported in lymphoepithelioma-like gastric carcinoma, the virus was also found in conventional adenocarcinomas. In the present study, 53 gastric carcinomas diagnosed in Sao Paulo State, Brazil, were evaluated for EBV infection by non-isotopic in situ hybridization with a biotinylated probe (Biotin-AGACACCGTCCTCACCACCCGGGACTTGTA) directed to the viral transcript EBER-I, which is actively expressed in EBV latently infected cells. EBV infection was found in 6 of 53 (11.32%) gastric carcinomas, mostly from male patients (66.7%), with a mean age of 59 years old. Most EBV-positive tumors were in gastric antrum. Two EBV-positive tumors (33.3%) were conventional adenocarcinomas, whereas four (66.7%) were classified as ...

2 MANECs are rare entities known to be associated with biological aggressiveness and poor patient survival, but otherwise remain incompletely characterized.3 In a recent study that compared CRC-NE to conventional colorectal carcinoma, CRC-NE was more frequently located in the right colon (76% vs. 46%), more often presented with metastasis (59% vs. 18%) and often had perineural (68%), lymphatic (97%), and venous (62%) invasion and high tumor budding (71%). BRAF V600E mutation was more common in CRC-NE compared with conventional CRC (53% vs. 12%). Neuroendocrine differentiation, high stage, BRAF mutation without microsatellite instability, and signet ring histology were all associated with poor overall survival.4 In the same study, CRC-NE was further divided into large cell neuroendocrine carcinoma (LCNEC), MANEC composed of LCNEC and conventional adenocarcinoma (MANEC-conventional type), and MANEC composed of LCNEC and signet ring cell carcinoma (MANEC-signet ring type). MANEC-signet ring type ...
The abdomen of Wistar rats was irradiated locally with 1000 to 2000 rads. Approximately 2 months following irradiation, visible nodules were found in the intestines of the groups receiving irradiation. Nodule incidence was 80 to 100% in groups that received 1750 or 2000 rads, 50% in the 1500-rad groups, and 3% in the 1000-rad groups, respectively.. The histology of the nodules revealed adenomatous hyperplasia, including invasion of submucosa, muscle layers, and serosa of the small intestine accompanied by an area of fibrous tissue resulting from desmoplastic reaction by irradiation injury.. ...
