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 ...

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

If you have been diagnosed with bronchoalveolar carcinoma, it is important to begin treatment immediately to prevent the malignant tumor from metastas
Pneumonic adenocarcinoma (P-ADC) is defined as a primary lung ADC with a radiological pneumonic presentation, usually referred to histologically as ADC with a mixed-invasive and BAC predominant subtype in the 2004 WHO classification. Surgery is the best therapy for resectable tumors since the effectiveness of chemotherapy is disappointing. In the advanced P-ADC diffuse/multifocal types of BAC, epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) (gefitinib and erlotinib) have shown promise, with some rapid, dramatic responses, possibly reflecting specific molecular differences from other non-small cell lung carcinomas ...

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 ...
This supplement to Oncology News International includes 17 reports on clinical trials of targeted therapies used alone, in combination with chemotherapy, or in combination with each other in the treatment of non-small-cell lung cancer (NSCLC), bronchoalveolar carcinoma, glioblastoma multiforme, and renal cell carcinoma. Included is a report on a novel targeted agent recently approved for treatment of NSCLC. 1
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 ...

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 ...

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.. ...

Thirty-seven nonhemolytic/nonbacteriocinogenic mutations in Enterococcus (Streptococcus) faecalis plasmid pAD1 were generated by Tn917 insertion. All were found to belong to one of two complementation classes. Each class of mutants secreted either hemolysin/bacteriocin (Hly/Bac) component A or L into the culture medium. DNA encoding Hly/Bac was cloned in Escherichia coli in which both components of the hemolysin were expressed individually and collectively. The region encoding components A and L was further defined by deletion analysis and physically mapped. A total of approximately 8.4 kilobases of pAD1 DNA were observed to be required for hemolysin expression. Hly/Bac activity of the wild-type and the inactive L substance was observed to be heat stable. Active Hly/Bac resulting from incubating separately secreted components A and L was also found to be heat stable. The results indicate that component A activates component L and that activated component L possesses the Hly/Bac activity. ...
Introduction: Lung adenocarcinoma has a complex variety of different hystopathologic subtypes with distinct epidemiology, pathology and prognosis. Pulmonary adenocarcinoma with enteric differentiation is a rare variant defined as a tumor with more than 50% of colorrectal-like components, immunohistochemistry (IHC) positive for at least one marker of enteric differentiation (CK20, CDX-2 or MUC2) and no evidence of other malignancies. Case Series: Patients were identified in a review of a set of adenocarcinomas, apparently originated in colon, but posteriorly accessed as lung adenocarcinomas. Median age was 57.6 years, were all Caucasian subjects and presented with metastatic disease. The median size were 6.3 cm at the time of diagnosis and all had spiculated shape forms at CT scans. Microscopic description revealed a lepidic (mucinous) adenocarcinoma in all five cases. Immunohistochemistry were positive for CK20 or CDX-2 in all these cases and was negative for CK7 in one patient. Conclusion: The use of
This intriguing case showed various histologic patterns, including a solid pattern (the main component), a bronchioloalveolar papillary pattern, lymphatic invasion, a sarcomatous pattern, and a hypocellular osteoblastic pattern.. Only a few cases of lung carcinoma with cyst formation have been reported [1-6]. The possible mechanisms for the development of malignant cysts include necrosis of the central core of the tumor followed by discharge of the necrotic content [6]. In this case report, the large cyst contained only necrotic material and no viable cells were included, although the viability of the tumor nodule itself was very high.. Etiothanatopathological (here, etiothanatopathology has been coined from etio logy, thanato logy, and patho logy) analysis of autopsy cases is important. The autopsy findings may give an insight into and lead to a better understanding of the heterogeneity and clonal expansion of lung adenocarcinoma. ...
