Lung cancer and occupation in a population-based case-control study.Consonni D, De Matteis S, Lubin JH, Wacholder S, Tucker M, Pesatori AC, Caporaso NE, Bertazzi PA, Landi MT Unit of Epidemiology, Department of Preventive Medicine, Fondazione IRCCS Ospedale Maggiore Policlinico, Mangiagalli e Regina Elena, Via San Barnaba, 8, 20122 Milano, Italy. dario.consonni@unimi.it The authors examined the relation between occupation and lung cancer in the large, population-based Environment And Genetics in Lung cancer Etiology (EAGLE) case-control study. In 2002-2005 in the Lombardy region of northern Italy, 2,100 incident lung cancer cases and 2,120 randomly selected population controls were enrolled. Lifetime occupational histories (industry and job title) were coded by using standard international classifications and were translated into occupations known (list A) or suspected (list B) to be associated with lung cancer. Smoking-adjusted odds ratios and 95% confidence intervals were calculated with logistic regression. For men, an increased risk was found for list A (177 exposed cases and 100 controls; odds ratio = 1.74, 95% confidence interval: 1.27, 2.38) and most occupations therein. No overall excess was found for list B with the exception of filling station attendants and bus and truck drivers (men) and launderers and dry cleaners (women). The authors estimated that 4.9% (95% confidence interval: 2.0, 7.8) of lung cancers in men were attributable to occupation. Among those in other occupations, risk excesses were found for metal workers, barbers and hairdressers, and other motor vehicle drivers. These results indicate that past exposure to occupational carcinogens remains an important determinant of lung cancer occurrence. Published 21 January 2010 in Am J Epidemiol, 171(3): 323-33. Articles on Lung Cancer published 21 January 2010: Inhibition of metastasis in a murine 4T1 breast cancer model by liposomes preventing tumor cell-platelet interactions. Clin Exp Metastasis, 27(1): 25-34. The interaction between circulating tumor cells and blood components, mainly platelets, plays an important role during metastasis. In this study, we prepared liposomes containing the platelet aggregation inhibitor Cilostazol (Cil-L). The objective of this study was to investigate the effect of this Cil-L on platelet aggregation and complex formation with murine 4T1 breast cancer cells in vitro and to determine their anti-metastatic potency in a spontaneous metastasis model of 4T1 breast cancer. ... [Abstract] [Full-text] Articles on Lung Cancer published 14 January 2010: The type I insulin-like growth factor receptor regulates cancer metastasis independently of primary tumor growth by promoting invasion and survival. Oncogene, 29(2): 251-62. The type I insulin-like growth factor receptor (IGF1R) regulates multiple aspects of malignancy and is the target of several drugs currently in clinical trials. Although the function of IGF1R in proliferation and survival is well studied, the regulation of metastasis by IGF1R is not as clearly delineated. Previous work showed that disruption of IGF1R signaling by overexpression of a dominant-negative IGF1R inhibited metastasis. To establish a clinically applicable approach to inhibition of ... [Abstract] [Full-text] Articles on Lung Cancer published 13 January 2010: Asbestos, lung cancers, and mesotheliomas: from molecular approaches to targeting tumor survival pathways. Am J Respir Cell Mol Biol, 42(2): 133-9. Fifteen years have passed since we published findings in the AJRCMB demonstrating that induction of early response fos/jun proto-oncogenes in rodent tracheal and mesothelial cells correlates with fibrous geometry and pathogenicity of asbestos. Our study was the first to suggest that the aberrant induction of signaling responses by crocidolite asbestos and erionite, a fibrous zeolite mineral associated with the development of malignant mesotheliomas (MMs) in areas of Turkey, led to altered gene ... [Abstract] [Full-text] Rapamycin-insensitive up-regulation of MMP2 and other genes in tuberous sclerosis complex 2-deficient lymphangioleiomyomatosis-like cells. Am J Respir Cell Mol Biol, 42(2): 227-34. Increased matrix metalloproteinase (MMP) activity has been implicated in the pathogenesis of lymphangioleiomyomatosis (LAM). The objective of this study was to investigate how tuberous sclerosis complex (TSC) 1 or TSC2 deficiency alters MMP expression and regulation. We studied immortalized cells that lack TSC2 derived from an angiomyolipoma of a patient with LAM, a TSC2 addback derivative, and murine embryonic fibroblast cells that lack Tsc1 or -2 and respective controls. Global gene ... [Abstract] [Full-text] Articles on Lung Cancer published 12 January 2010: Quality assessment of DNA derived from up to 30 years old formalin fixed paraffin embedded (FFPE) tissue for PCR-based methylation analysis using SMART-MSP and MS-HRM. BMC Cancer, 9: 453. BACKGROUND: The High Resolution Melting (HRM) technology has recently been introduced as a rapid and robust analysis tool for the detection of DNA methylation. The methylation status of multiple tumor suppressor genes may serve as biomarkers for early cancer diagnostics, for prediction of prognosis and for prediction of response to treatment. Therefore, it is important that methodologies for detection of DNA methylation continue to evolve. Sensitive Melting Analysis after Real Time - ... [Abstract] [Full-text] Articles on Lung Cancer published 8 January 2010: In vivo positron emission tomography (PET) imaging of mesenchymal-epithelial transition (MET) receptor. J Med Chem, 53(1): 139-46. We report the radiosynthesis and evaluation of 3-[3,5-dimethyl-4-(4-[11C]methylpiperazinecarbonyl)-1H-pyrrol-2-ylmethylene]-2-oxo-2,3-dihydro-1H-indole-5-sulfonic acid (3-chlorophenyl)methylamide, termed [11C]SU11274 ([11C]14) for in vivo imaging of mesenchymal-epithelial transition (MET) receptor by positron emission tomography (PET). Following the synthesis of the precursor (13) that was achieved in 10 steps with a total yield of 9.7%, [11C]14 was obtained through radiomethylation in a range ... [Abstract] [Full-text] Distinct patterns of cytokine and angiogenic factor modulation and markers of benefit for vandetanib and/or chemotherapy in patients with non-small-cell lung cancer. J Clin Oncol, 28(2): 193-201. PURPOSE: There is an unmet need for biomarkers for identifying patients likely to benefit from anticancer treatments, selecting dose, and understanding mechanisms of resistance. Plasma vascular endothelial growth factor (VEGF) and soluble VEGF receptor 2 (sVEGFR-2) are known to be modulated by VEGF pathway inhibitors. It is unknown whether chemotherapy or VEGFR inhibitor/chemotherapy combinations induce changes in these or other cytokines and angiogenic factors (CAFs) and whether such changes ... [Abstract] [Full-text] Clinical definition of acquired resistance to epidermal growth factor receptor tyrosine kinase inhibitors in non-small-cell lung cancer. J Clin Oncol, 28(2): 357-60. Ten percent of North American patients with non-small-cell lung cancer have tumors with somatic mutations in the gene for the epidermal growth factor receptor (EGFR). Approximately 70% of patients whose lung cancers harbor somatic mutations in exons encoding the tyrosine kinase domain of EGFR experience significant tumor regressions when treated with the EGFR tyrosine kinase inhibitors (TKIs) gefitinib or erlotinib. However, the overwhelming majority of these patients inevitably acquire ... [Abstract] [Full-text] © 2004-2010 Lung Cancer Research Today. All Rights Reserved. |
