BACKGROUND: The cytological analysis of peritoneal effusions serves as a diagnostic and prognostic aid for either primary or metastatic diseases. Among the different cytological preparations, liquid based cytology (LBC) represents a feasible and reliable method ensuring also the application of ancillary techniques (i.e immunocytochemistry-ICC and molecular testing). METHODS: We recorded 10348 LBC peritoneal effusions between January 2000 and December 2014. They were classified as non-diagnostic (ND), negative for malignancy-NM, atypical-suspicious for malignancy-SM and positive for malignancy-PM...

BACKGROUND: Studies in other countries have generally found approximately 4% of current cancers to be attributable to past occupational exposures. This study aimed to estimate the future burden of cancer resulting from current occupational exposures in Australia. METHODS: The future excess fraction method was used to estimate the future burden of occupational cancer (2012-2094) among the proportion of the Australian working population who were exposed to occupational carcinogens in 2012...

Zeeshan Ahmad, Robert A Kratzke
Oncolytic virotherapy is the use of replication-competent viruses to treat malignancies. The potential of oncolytic virotherapy as an approach to cancer therapy is based on historical evidence that certain viral infections can cause spontaneous remission of both hematologic and solid tumor malignancies. Oncolytic virotherapy may eliminate cancer cells through either direct oncolysis of infected tumor cells or indirect immune-mediated oncolysis of uninfected tumor cells. Recent advances in oncolytic virotherapy include the development of a wide variety of genetically attenuated RNA viruses with precise cellular tropism and the identification of cell-surface receptors that facilitate viral transfer to the tissue of interest...

BACKGROUND: Reduced expression in immortalized cell (REIC)/Dickkoph-3 (DKK3) is a tumor-suppressor gene, and its overexpression by adenovirus vector (Ad-REIC) exhibits a remarkable therapeutic effect on various human cancer types through a mechanism triggered by endoplasmic reticulum stress. MATERIALS AND METHODS: We examined the direct anti-tumor effect of Ad-REIC gene therapy on lung cancer and malignant mesothelioma cell lines in vitro, and the distant bystander effect using immunocompetent mouse allograft models with bilateral flank tumors...

Asbestos is a mineral-mined form the rocks, consisting in amosite (brown asbestos), crocidolite (blue asbestos) and÷or chrysotile (white asbestos) used in many industries. Researches about the exposure to asbestos dust and asbestosis related diseases started almost a century ago. The first case report of fatal asbestosis disease was published in 1906, in England, by Dr. Hubert Montague Murray. A decade after, asbestos "curious bodies" were firstly described in the lung tissue by Cooke (1926) and McDonald (1927)...

Chest pain represents one of the most frequent symptoms of pulmonary diseases, in addition to dyspnea and cough. The broad differential diagnostics include the intensely painful but prognostically benign acute pleurisy as well as potentially life-threatening events, such as acute pulmonary embolism or malignant chest diseases. Primary spontaneous pneumothorax is characterized by acute chest pain. Pain associated with a respiratory infection, such as pneumonia rarely poses a difficult diagnostic problem. Painful diseases of the lungs can be differentiated in an initial approach by asking the patient if the pain is related to breathing, which is characteristic of pleuritic chest diseases...

BRCA1-associated protein 1 (BAP1) is a tumor suppressor gene involved in regulation of the cell cycle, cellular differentiation, repair of DNA damage and apoptosis. In the distinction of malignant mesothelioma from benign mesothelial proliferations, immunohistochemical loss of BAP1, the protein expressed by the BAP1 gene, has proven highly specific for malignant mesothelioma. However, few studies have investigated the rate of BAP1 loss in tumors that commonly metastasize to the pleura. Our objective is to determine the rate of BAP1 loss in non-small cell lung cancer (NSCLC)...

REVIEW
Takayuki Fukui, Kohei Yokoi
Patients with non-small cell lung cancer (NSCLC) associated with carcinomatous pleuritis are currently classified as having stage IV disease per the 7(th) edition of the tumor-node-metastasis (TNM) system, which means that the disease is deemed incurable. In fact, the 5-year survival rate of these patients was only 2% in a large global cohort collected by the International Association for the Study of Lung Cancer. However, patients with carcinomatous pleuritis have heterogeneous conditions. Some have minimal pleural effusion, which is first detected at thoracotomy; some have numerous pleural nodules without any effusion; and others have massive effusion and nodules with symptoms...

The recent finding of asbestos fibres in drinking water (up to 700.000 fibres/litres) in Tuscany (Central Italy) leads to concerns about health risks in exposed communities. Exposure to asbestos has been linked with cancer at several levels of the gastrointestinal tract, and it has been documented, in an animal model, a direct cytotoxic effect of asbestos fibres on the ileum. It has been recently described a possible link between asbestos and intrahepatic cholangiocarcinoma, and asbestos fibres have been detected in humans in histological samples from colon cancer and in gallbladder bile...

The presence of multiple primary tumors (MPT) in a single patient has been identified with an increasing frequency. A critical issue is to establish if the second tumor represents an independent primary cancer or a metastasis. Therefore, the assessment of MPT clonal origin might help understand the disease behavior and improve the management/prognosis of the patient.Herein, we report a 73-year-old male smoker who developed 2 primary lung cancers (adenocarcinoma and squamous cell carcinoma) and a malignant peritoneal mesothelioma (PM)...

Exposure to asbestos is associated with the development of mesothelioma. In addition to asbestos, other fibers have been identified as risk factors for malignant and non-malignant diseases of the lungs. Among these, fluoro-edenite (FE) was found in patients from Biancavilla (Sicily, Italy) with pleural and lung disease, suggesting its role for tumor expansion. In this context, the identification of early biomarkers useful for the diagnosis of cancer is mandatory. Fibulin-3 represents an important marker for the diagnosis of mesothelioma...

The high mortality of solid tumors can be attributed to their invasive and metastatic potential that is based on their migration and proliferation. Importantly, growth factor receptor (GF) signaling pathways regulating proliferation and migration are often affected by oncogenic mutations and are important targets for antitumor therapy. We found positive correlation between migration and proliferation in melanoma and lung cancer cells using videomicroscopy, not supporting the "go or grow" hypothesis. Furthermore, the invasion into collagen I matrices from brain tumor spheroids was not impaired upon the inhibition of proliferation...

BACKGROUND: Some trials recently demonstrated the benefit of targeted treatment for malignant disease; therefore, adequate tissues are needed to detect the targeted gene. Pleural biopsy using flex-rigid pleuroscopy and pleural effusion cell block analysis are both useful for diagnosis of malignancy and obtaining adequate samples. The purpose of our study was to compare the diagnostic utility between the two methods among patients with malignant pleural disease with effusion. METHODS: Data from patients who underwent flex-rigid pleuroscopy for diagnosis of pleural effusion suspicious for malignancy at the National Cancer Center Hospital, Japan between April 2011 and June 2014 were retrospectively reviewed...

Asbestos exposure causes malignant tumors such as lung cancer and malignant mesothelioma. Based on our hypothesis in which continuous exposure to asbestos of immune cells cause reduction of antitumor immunity, the decrease of natural killer cell killing activity with reduction of NKp46 activating receptor expression, inhibition of cytotoxic T cell clonal expansion, reduced CXCR3 chemokine receptor expression and production of interferon-γ production in CD4+ T cells were reported using cell line models, freshly isolated peripheral blood immune cells from health donors as well as asbestos exposed patients such as pleural plaque and mesothelioma...

PURPOSE: Psychological distress which adversely affects a person's experience of cancer has been shown to be highly prevalent in patients with mesothelioma. Historically, the assumption has been made that the evidence guiding the supportive care needs for lung cancer is relevant to those with mesothelioma. The objective of the study was to evaluate if the psychological care needs differ between patients with pleural mesothelioma and those with advanced lung cancer. METHODS: A search of MEDLINE, CINAHL, PsycARTICLES, Psychology and Behavioural Sciences Collection, PsycINFO databases, grey literature and the Cochrane Library of Systematic Reviews identified 17 studies meeting a predefined inclusion criteria...

Mesothelin is a tumor antigen that is highly expressed in many human cancers, including malignant mesothelioma and pancreatic, ovarian, and lung adenocarcinomas. It is an attractive target for cancer immunotherapy because its normal expression is limited to mesothelial cells, which are dispensable. Several antibody-based therapeutic agents as well as vaccine and T-cell therapies directed at mesothelin are undergoing clinical evaluation. These include antimesothelin immunotoxins (SS1P, RG7787/LMB-100), chimeric antimesothelin antibody (amatuximab), mesothelin-directed antibody drug conjugates (anetumab ravtansine, DMOT4039A, BMS-986148), live attenuated Listeria monocytogenes-expressing mesothelin (CRS-207, JNJ-64041757), and chimeric antigen receptor T-cell therapies...

ABSTRACT BACKGROUND: Monoclonal antibodies have become attractive clinical anti-cancer drugs in the last 3 decades due to their targeting specificity and suitable pharmacokinetic properties. Mesothelin is a tumor-associated antigen with limited expression in normal tissues. It is frequently over-expressed on the cell membrane of a number of epithelial malignancies (e.g. mesothelioma, pancreatic, ovarian, lung, triple negative breast and gastric cancers). METHODS: Mesothelin is validated as a suitable antibody target for cancer therapy...

BACKGROUND: FAS-670 A>G (rs1800682) and FASL-844 C>T (rs763110) polymorphisms have been previously correlated with clinical outcome of non-small cell lung cancer (NSCLC) and breast and bladder cancers. We investigated the influence of these polymorphisms on clinical outcome of malignant pleural mesothelioma (MPM) patients. PATIENTS AND METHODS: In this cohort study (NCT02269878), 68 epithelioid MPM Egyptian patients treated with first-line platinum-based chemotherapy were recruited in the period between April 2014 and May 2015...

We examined the development of knowledge concerning the risks posed by asbestos to seamen working aboard merchant ships at sea (i.e. commercial, rather than naval vessels). Seamen were potentially exposed to "in-place" asbestos on merchant ships by performing intermittent repair and maintenance tasks. We reviewed studies measuring airborne asbestos onboard merchant ships and health outcomes of merchant seamen, as well as studies, communications, and actions of U.S. organizations with roles in maritime health and safety...
