September 19th, 2008. Comparative immunohistochemistry of L19 and F16 in non-small cell lung cancer and mesothelioma: Two human antibodies investigated in clinical trials in patients with cancer
In our analysis, the anti-tenascin F16 antibody was found to generally exhibit a stronger staining of desmoplastic stroma surrounding tumor. This superior performance was found to be particularly striking in the case of low-grade non-small cell lung cancer.
September 19th, 2008. Preoperative staging of mesothelioma by 18F-fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography fused imaging and mediastinoscopy compared to pathological findings after extrapleural pneumonectomy
Conclusions: Non-curative surgery is avoided in 29% out of 42 MPM patients by preoperative PET/CT and in further 14% by mediastinoscopy. Even though both procedures are valuable, there are false negative findings with both, urging for even more accurate staging procedures.
September 18th, 2008. Multicystic peritoneal mesothelioma is an uncommon lesion that is most often discovered incidentally
Abstract Symptoms are unusual. The lesion is benign with a favourable prognosis but local recurrence is reported not to be rare, and in a few cases malignant transformation has been described.
September 17th, 2008. Orally Ingested Chrysotile Asbestos Affects Rat Lungs and Pleura
The authors observed mesothelial proliferation in all group B rats at the end of 12 months. Ingested asbestos traveled from the gastrointestinal system to the lungs, likely via a lymphohematological route, leading to mesothelial proliferation, which may lead to malignancies.
September 17th, 2008. Peritoneal Mesotheliomas: Clinicopathologic Features, CT Findings, and Differential Diagnosis
Conclusion: The clinicopathologic features of peritoneal mesotheliomas vary among the subtypes such as malignant mesotheliomas, cystic mesotheliomas, and well-differentiated papillary mesotheliomas, and accordingly, there is a spectrum of CT appearances.
September 17th, 2008. ‘Hands of Time’: the experience of establishing a support group for people affected by mesothelioma
The structure and process of developing and running the group are described and the challenges involved are discussed. The findings of a small evaluation of the group are presented.
September 17th, 2008. Metastasis of Malignant Peritoneal Epithelioid Mesothelioma in Endoscopic Gastric Biopsy: A Diagnostic Pitfall
Conclusions: Metastases of malignant peritoneal mesotheliomas are unusual, and a predominantly gastrointestinal localization is rare. Pathologists should be aware of this possibility to avoid misdiagnosis, particularly in small biopsy specimens.
September 17th, 2008. Proteasome Inhibitor MG132 Induces Apoptosis and Inhibits Invasion of Human Malignant Pleural Mesothelioma Cells
Meanwhile, subapoptotic doses of MG132 inhibited the invasion of both MPM cell lines through reducing Rac1 activity. These observations demonstrate that MG132 possesses proapoptotic and anti-invasion activities in human MPM cells, therefore encouraging further investigations on the value of PIs for treating MPM.
September 17th, 2008. Raw single-wall carbon nanotubes induce oxidative stress and activate MAPKs, AP-1, NF-kappaB, and Akt in normal and malignant human mesothelial cells
Conclusions: The cellular and molecular findings reported here do suggest that SWCNTs can cause potentially adverse cellular responses in mesothelial cells through activation of molecular signaling associated with oxidative stress, which is of sufficient significance to warrant in vivo animal exposure studies.
September 16th, 2008. Computed Tomography, Positron Emission Tomography, Positron Emission Tomography/Computed Tomography, and Magnetic Resonance Imaging for Staging of Limited Pleural Mesothelioma: Initial Results
Conclusion: PET/CT makes it possible to stage patients with limited MPM with high accuracy and low interobserver variability.
September 16th, 2008. Survival of pleural malignant mesothelioma in Italy: a population-based study
Age and morphology were the main prognostic factors. Results regarding the effect of treatment were disappointing but may be useful to assess the future impact, at the population level, of recently introduced therapies.
September 16th, 2008. Survival of peritoneal malignant mesothelioma in Italy: a population-based study
Treatment was not associated with a statistically significant improvement in survival, but our study included cases first diagnosed before the introduction of the most recent therapeutic approaches. This provides a large historical comparison for future studies on survival trends at the population level.
September 13th, 2008. Pathology of Primary Tumours of the Pleura
Besides other rare primary tumours of the pleura, the differential diagnoses of malignant mesotheliomas comprise carcinomatous pleuritis of intra- and extrapulmonary malignancies. Especially in early tumour stages, the differentiation from reactive pleural changes requires a close interdisciplinary cooperation with a careful correlation between histopathological findings and clinical presentation.
September 13th, 2008. Pathogenesis of malignant pleural mesothelioma and the role of environmental and genetic factors
Conclusion: Many risk factors for MPM development have been recognized including environmental exposures, genetic susceptibility, viral contamination, and radiation. In this review, we discuss the current molecular and genetic contributors to MPM pathogenesis and the risk factors associated with these carcinogenic processes.
September 12th, 2008. A review of intensity-modulated radiation therapy
In some situations, IMRT allows more conformal radiation therapy to complex targets within the lung. As problems related to organ motion are increasingly addressed, the use of IMRT in the treatment of lung cancer, particularly in non-small cell lung cancer and mesothelioma, continues to rise.
September 12th, 2008. Inguinal lymph node as the only evidence of progressive lung cancer
The primary tumours of these cases were malignant mesothelioma, salivary duct and breast carcinoma. In this paper, we report a case of carcinoma of the lung metastatic to an inguinal lymph node as the only evidence of progressive lung cancer.
September 9th, 2008. Characteristics and modifying factors of asbestos-induced oxidative DNA damage
p. chrysotile, our data suggest that asbestos-associated catalytic iron, whether constitutional or induced by other mechanisms, plays an important role in asbestos-induced carcinogenesis and that chemoprevention may be possible through targeting the catalytic iron.
September 9th, 2008. Clinical consequences of asbestos-related diffuse pleural thickening: A review
It causes a restrictive defect on lung function and may rarely result in respiratory failure and death. Treatment is primarily supportive.

September 6th, 2008. Prevention of malignant seeding at drain sites after invasive procedures (surgery and/or thoracoscopy) by hypofractionated radiotherapy in patients with pleural mesothelioma
Discussion: The present study shows the efficacy and safety of local radiotherapy in preventing malignant seeding after thoracoscopy in patients with pleural mesothelioma although larger prospective trials are probably still needed to validate this treatment approach.
September 5th, 2008. Asbestos Surveillance Program Aachen (ASPA): initial results from baseline screening for lung cancer in asbestos-exposed high-risk individuals using low-dose multidetector-row CT
28% (8/187) at baseline screening with an additional large number of indeterminate pulmonary nodules. Low-dose MDCT proved to be feasible in this highly selected population.
