The association between atypical adenomatous hyperplasia and primary lung cancer. (1/11)

Atypical adenomatous hyperplasia (AAH) has been suggested as the adenoma in an adenoma-carcinoma sequence in the lung periphery. From 1989-1998, we undertook a systematic, prospective search for AAH in lungs resected for cancer. AAH was found in 67 of 554 patients (12. 1%) with primary lung carcinoma (9.2% in male patients and 19.0% in females). AAH was found in lungs bearing adenocarcinoma (23.2%) more frequently than with large cell undifferentiated carcinoma (12.5%) or squamous carcinoma (3.3%). A greater percentage of females with adenocarcinoma had AAH (30.2%) than did males with adenocarcinoma (18.8%). Numbers of AAH ranged from 1-42 per patient and more patients had small numbers of AAH, although 12 patients had 6 or more AAH foci. Larger numbers of AAH tended to be found in adenocarcinoma-bearing lungs. Ten of the 67 patients with AAH and primary lung carcinoma (15%) had multiple primary cancers (range 2-6), all of which were adenocarcinoma. Synchronous cancers were rare in lung tumour-bearing resections without AAH. Patients with AAH show no difference in post-operative survival to those without, for all stages of carcinoma and for Stage I disease alone. This study provides evidence for a strong association between atypical adenomatous hyperplasia and primary lung adenocarcinoma and lends weight to the AAH/adenoma-carcinoma hypothesis.  (+info)

Atypical adenomatous hyperplasia of the lung: a probable forerunner in the development of adenocarcinoma of the lung. (2/11)

An increasingly large body of work suggests that atypical adenomatous hyperplasia (AAH) of the lung may be a forerunner of pulmonary adenocarcinoma. Recognizing this fact, the World Health Organization now acknowledges the existence of AAH while noting difficulties that may be encountered in distinguishing AAH from the nonmucinous variant of bronchioloalveolar carcinoma. Regrettably, a universally acceptable definition of morphologic criteria for the diagnosis of AAH has not been achieved. This review of the literature examines the epidemiology, gross appearance, light microscopic findings, morphometry, immunohistochemistry, and molecular features of AAH and suggests a set of histopathologic features that may help the practicing pathologist identify this intriguing lesion. These features include the following: irregularly bordered focal proliferations of atypical cells spreading along the preexisting alveolar framework; prominent cuboidal to low columnar alveolar epithelial cells with variable degree of atypia but less than that seen in adenocarcinoma; increased cell size and nuclear-cytoplasmic ratio with hyperchromasia and prominent nucleoli, generally intact intercellular attachment of atypical cells with occasional empty-looking spaces between them without high cellularity and without tufting or papillary structures; and slight thickening of the alveolar walls on which the AAH cells have spread, with some fibrosis but without scar formation or significant chronic inflammation of the surrounding lung tissue. Several lines of evidence indicate that AAH is a lesion closely associated with adenocarcinoma of the lung, suggesting AAH may be involved in the early stage of a complex multistep carcinogenesis of pulmonary adenocarcinoma.  (+info)

Atypical adenomatous hyperplasia of the lung: a clinicopathological study of 118 cases including cases with multiple atypical adenomatous hyperplasia. (3/11)

BACKGROUND: Atypical adenomatous hyperplasia (AAH) of the lung is a putative precursor lesion of adenocarcinoma, according to many immunohistochemical and genetical studies, but few clinicopathological studies on a large number of cases have been reported. The aim of this study was to clarify the clinicopathological characteristics of lung cancer patients with AAH lesions. METHODS: A retrospective study was carried out on 508 consecutive primary lung cancer patients operated on at National Cancer Center Hospital East. The relationship between the number and location of AAH lesions and the clinicopathological features of the lung cancer patients was analysed statistically. RESULTS: A total of 311 AAH lesions were found in 118 (23.2%) of the 508 cases. AAH lesions were detected in 121 of 572 lobes examined, usually in both upper lobes, and occurred most frequently in patients with adenocarcinoma (OR 2.97; 95% CI 1.82 to 4.85). AAH lesions were more frequently detected in patients with multiple primary carcinomas than in those with a single carcinoma (OR 3.06; 95% CI 1.56 to 6.00). The presence of AAH lesions was not significantly correlated with sex, age, smoking status, familial history of malignancy, or preceding malignancy. Patients with multiple AAH lesions were found to have a significantly higher frequency of preceding malignancies. CONCLUSIONS: The present study highlights the clinicopathological characteristics of AAH lesions, showing them to be significantly associated with both adenocarcinoma and multiple primary carcinoma of the lung and suggesting common factors in the histogenesis of multiple AAH lesions and preceding malignancy.  (+info)

Fine chromosomal localization of the mouse Par2 gene that confers resistance against urethane-induction of pulmonary adenomas. (4/11)

BALB/cByJ mice are 14 times more resistant to urethane-induction of pulmonary adenomas than the susceptible A/J strain. Our previous linkage analysis of (A/J x BALB/cByJ)F1 x A/J backcross mice provided statistical evidence that a major resistance locus of BALB/cByJ with a dominant effect, designated Par2 (Pulmonary adenoma resistance 2), exists within an approximately 25 cM section of distal chromosome 18. To facilitate molecular identification of the Par2 locus, the present study was conducted to finely localize its chromosomal position utilizing Par2-congenic mice. Male BALB/cByJ mice were mated with female C57BL/6J mice carrying recessive Par2 alleles and their male F1 progeny were backcrossed to female BALB/cByJ mice. A male backcross mouse heterozygous within the Par2 interval of 25 cM was randomly selected and again backcrossed to female BALB/cByJ mice. This backcross-selection cycle was simply repeated to produce semi-congenic mice with a general BALB/cByJ genetic background except for the Par2 interval, where the mice were heterozygous with paternal C57BL/6J alleles and maternal BALB/cByJ alleles. After the 6th or 7th backcross, nine male mice possessing a recombination within the paternal Par2 interval were retained and crossed to female A/J mice. Resultant progeny were treated with urethane and examined for lung tumor development in order to deduce the Par2 genotypes of the recombinants through linkage analysis. By comparing the deduced Par2 genotype of each recombinant with its recombinational breakpoint, the Par2 locus was confined to an approximately 0.5 cM region flanked by D18Mit103 and D18Mit188 loci. Our results indicate that fully congenic mice conventionally established by at least nine simple backcrosses or by the speed congenic method are not necessarily required for fine mapping of quantitative trait loci. In the case of the Par2 locus, we found that semi-congenic mice after as few as four simple backcrosses were useful for this purpose. The map information obtained in this study should enable subsequent positional cloning of the Par2 gene.  (+info)

A case of multiple atypical adenomatous hyperplasia of the lung detected by computed tomography. (5/11)

Multiple atypical adenomatous hyperplasia (AAH) of both lungs in a 72-year-old male, detected by computed tomography, is reported. The lesions of the right lung were resected for diagnosis via video-assisted thoracoscopic surgery (VATS). The resected specimen had 22 AAH lesions up to 10 mm in size. For nine of these lesions, the expressions of carcinoembryonic antigen (CEA), c-erbB-2 oncoprotein and p53 gene product were examined by immunohistochemistry and the loss of heterozygosity (LOH) on chromosomes was investigated by polymerase chain reaction analysis. These lesions showed a variety of expressions for CEA, c-erbB-2 and p53 oncoprotein. Three of the nine lesions showed LOH on chromosome 13q, although this was not exhibited in the largest one. These results indicate that each AAH in this case has independent genetic abnormalities and is multicentric.  (+info)

Multiple atypical adenomatous hyperplasia with synchronous multiple primary bronchioloalveolar carcinomas. (6/11)

We report a case of multiple atypical adenomatous hyperplasia (AAH) associated with synchronous multiple primary bronchioloalveolar carcinomas (BACs). A 58-year-old man was visited for bronchial asthma. A chest computed tomography (CT) scan revealed small, multiple nodules with ground glass attenuation (GGA) throughout both lungs, predominantly in the upper lobes. A high resolution CT (HRCT) scan disclosed well-defined nodules with uniform GGA. Thoracoscopic wedge lung biopsy confirmed the diagnosis. The patient was treated with chemotherapy and had stable disease for two years. It is important to recognize that multiple AAH associated with multiple BACs can present as diffuse, well-defined nodules with uniform GGA on HRCT.  (+info)

Epstein-Barr virus nuclear antigen 1 does not induce lymphoma in transgenic FVB mice. (7/11)

The lymphoma-inducing potential of Ig heavy-chain enhancer- and promoter-regulated Epstein-Barr virus (EBV) nuclear antigen 1 (EBNA1) was evaluated in three transgenic FVB mouse lineages. EBNA1 was expressed at a higher level in transgenic B220(+) splenocytes than in EBV-infected lymphoblastoid cell lines. EBNA1 was also expressed in B220(-) transgenic splenocytes and thymocytes. Before killing and assessments at 18-26 months, EBNA1-transgenic mice did not differ from control mice in mortality. At 18-26 months EBNA1-transgenic mice did not differ from littermate control in ultimate body weight, in spleen size or weight, in lymph node, kidney, liver, or spleen histology, in splenocyte fractions positive for cluster of differentiation (CD)3epsilon, CD4, CD8, CD62L, B220, CD5, IgM, IgD, MHC class II, CD11b, or CD25, or in serum IgM, IgG, or total Ig levels. Lymphomas were not found in spleens or other organs of 18- to 26-month-old EBNA1-transgenic (n=86) or control (n=45) FVB mice. EBNA1-transgenic lineages had a higher pulmonary adenoma prevalence than did littermate controls (39% versus 7%). However, the adenoma prevalence was not higher in EBNA1-transgenic mice than has been described for FVB mice, and EBNA1 was not expressed in normal pulmonary epithelia or adenomas.  (+info)

Epidermal growth factor receptor gene mutations in atypical adenomatous hyperplasias of the lung. (8/11)

Activating epidermal growth factor receptor (EGFR) gene mutations are frequently detected in lung adenocarcinomas, especially adenocarcinomas with a nonmucinous bronchioloalveolar carcinoma component. EGFR-mutated lung adenocarcinomas respond well to EGFR tyrosine kinase inhibitors. We previously found that most (88%) pure nonmucinous bronchioloalveolar carcinomas (adenocarcinoma in situ) already harbor EGFR mutations, indicating that the mutations are an early genetic event in the pathogenesis. We examined 54 atypical adenomatous hyperplasias, precursor lesions of lung adenocarcinomas, obtained from 28 Japanese patients for the hotspot mutations of EGFR exons 19 and 21 and K-ras codon 12. EGFR mutations were observed in 17 of the 54 (32%) atypical adenomatous hyperplasias examined: Ten and seven atypical adenomatous hyperplasias had deletion mutations at exon 19 or point mutations (L858R) at exon 21, respectively. We did not observe apparent histological differences between atypical adenomatous hyperplasias with and without EGFR mutations. K-ras mutation (G12S) was detected in only one atypical adenomatous hyperplasia. As EGFR mutational frequency of atypical adenomatous hyperplasias was much lower than that of nonmucinous bronchioloalveolar carcinomas, we surmise that EGFR-mutated atypical adenomatous hyperplasias, but not atypical adenomatous hyperplasias with wild-type EGFR, are likely to progress to nonmucinous bronchioloalveolar carcinomas.  (+info)

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 ...

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 ...

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 ...

We report on 2 infants with PHHI for whom focal lesions of the pancreas were diagnosed during laparoscopy and laparoscopically enucleated. Both children were cured at the age of 1 month. One year after surgery, both patients are well and normoglycemic. Functional data from patient tissue analyses and genotyping in both cases revealed that PHHI was a consequence of defects in β-cell KATP channels. For both children, mutations in the SUR1 gene were found; the mutations were of paternal origin in both cases, as reported for focal hyperinsulinism. The focal origins of PHHI were confirmed with histologic diagnoses.. Focal adenomatous hyperplasia as a cause of PHHI was observed first by Kloppel et al7 in 1975 and was noted by Goossens et al8 in 1989 in a large study of 24 pancreata from surgically treated patients with PHHI. Since those observations, focal lesions as a cause of intractable hyperinsulinism have been consistently reported. The presumed incidence may be as high as 30% to 60% of cases of ...
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 ...
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 ...

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..

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
Contagious Respiratory Tumours Also known as: Jaagsiekte, Pulmonary Adenomatosis and Adenomatosis - Pulmonary There are two neoplastic conditions which result in contagious respiratory tumours (or contagious lung cancer) in small ruminants: Ovine Pulmonary Adenocarcinoma (also known as ODA, She...

ABSTRACT: Beaked whales are among the least known group of cetaceans, and information regarding their pathology and parasitology are especially scarce. We describe a case of significant parasitism by a trematode found in the liver of an adult male Hubbs beaked whale Mesoplodon carlhubbsi that stranded in Hokkaido, Japan. Post-mortem examinations revealed a localised area of discolouration restricted to the hilar region of the left hepatic lobe, where spindle-shaped trematodes occupied the dilated and hypertrophic bile ducts. Histologically, the intrahepatic bile ducts were characterised by adenomatous hyperplasia with goblet cell metaplasia of the biliary epithelium. Findings in the adjacent hepatic parenchyma included pseudocarcinomatous ductular reactions obliterating hepatocytes, a histomorphology not previously reported in marine mammals. Morphological identification of the trematode corresponded to Oschmarinella macrorchis, which has only been reported once in a Stejnegers beaked whale M. ...

If youre asking why should a first aider always be present at a cricket game, the answer is that they can make a positive difference if someone is injured.
Clinical treatments for cats with Functional Thyroid Adenomatous Hyperplasia typically include the following three options:. » Daily treatment with an anti-thyroid drug (typically methimazole). The primary problem with this treatment is that it is not a cure. Treatment will be needed to be given every day (one pill given once or twice a day) for the rest of the felines life. Side effects may include vomiting, anorexia, fever, anemia and lethargy.. » Surgical intervention is another effective treatment using a procedure called a thyroidectomy (the removal of the thyroid gland). This option is usually selected when only one thyroid lobe is involved. While it offers a cure; it is possible for the hyperthyroidism to re-occur. A feline with kidney disease cannot have this surgery. A possible side effect is hypothyroidism (an underactive thyroid) which will require life-long thyroid supplementation.. » Radioactive Iodine Treatment is a fairly new treatment that provides a permanent cure in 95% ...
TY - JOUR. T1 - Loss of heterozygosity patterns of sclerosing hemangioma of the lung and bronchioloalveolar carcinoma indicate a molecular pathogenesis. AU - Dacic, Sanja. AU - Sasatomi, Eizaburo. AU - Swalsky, Patricia A.. AU - Kim, Dong Won. AU - Finkelstein, Sydney D.. AU - Yousem, Samuel A.. N1 - Copyright: Copyright 2008 Elsevier B.V., All rights reserved.. PY - 2004/8. Y1 - 2004/8. N2 - Context.-The histogenesis and origin of sclerosing hemangioma (SH) of lung were uncertain for many years. Many immunohistochemical, ultrastructural, and recent molecular studies support the hypothesis that SH is a neoplasm originating from the cells of the terminal lobular unit, similar to the nonmucinous variant of bronchioloalveolar carcinoma (BAC). Most cases of SH are benign, but they can metastasize to the regional lymph nodes. Objective.-To compare the patterns of allelic loss of tumor suppressor genes in SH and BAC by microdissection-based genotypic analysis. Design.-Microdissection-based loss of ...
