Histopathological typing in diffuse malignant epithelioid mesothelioma: implication for prognosis and molecular basis.

Pathology 2021 May 6. Epub 2021 May 6.

University Hospital of Saint Etienne, North Hospital, Department of Pathology, Saint Etienne, France; Corneal Graft Biology, Engineering, and Imaging Laboratory, BiiGC, EA2521, Federative Institute of Research in Sciences and Health Engineering, Faculty of Medicine, Jean Monnet University, Saint-Etienne, France.

The prognostic impact of tumour grading, cytological and architectural patterns and stromal features in diffuse pleural malignant epithelioid mesothelioma (MEM) has been partly studied but not correlated to molecular features. We performed a retrospective study on 92 MEM in our department in order to assess the prognostic role of architectural and stromal patterns, especially tumour to stroma ratio. Secondly, based on The Cancer Genome Atlas (TCGA) database, we analysed the differentially expressed genes in prognostic groups of interest. Read More

Pan Afr Med J 2021 27;38:92. Epub 2021 Jan 27.

Service d´Oncologie Médicale, Centre Hospitalier Universitaire (CHU) Hassan II, Fès, Maroc.

Primary malignant mesothelioma of the ovary (PMMO) is an extremely rare tumor which can develop from mesothelial cells. This neoplasia is caused predominantly by exposure to asbestos or other cancer-causing agents. Preoperative assessment, based on computed tomography (CT) scan, magnetic resonance imaging and positron emission tomography, is essential for cancer staging. Read More

Tract metastasis in patients with long-term pleural catheter-computed tomography diagnosis and longitudinal assessment.

Eur Radiol 2021 Apr 15. Epub 2021 Apr 15.

Department of Internal Medicine, Interventional Respirology Service, The Ottawa Hospital Research Institute, Ottawa, Canada.

Objectives: Long-term indwelling pleural catheters (IPC), used for the management of malignant pleural mesothelioma (MPM), may lead to catheter tract metastasis (CTM). While computed tomography (CT) is valuable for diagnosis, no studies have assessed CT manifestations of CTM. Our goal is to describe the incidence, CT appearances, and temporal evolution of CTM in MPM. Read More

Near Infrared Photoimmunotherapy for Mouse Models of Pleural Dissemination.

J Vis Exp 2021 02 9(168). Epub 2021 Feb 9.

Respiratory Medicine, Nagoya University Graduate School of Medicine; Nagoya University Institute for Advanced Research; B3-Unit, Advanced Analytical and Diagnostic Imaging Center (AADIC)/Medical Engineering Unit (MEU), Nagoya University Institute for Advanced Research;

The efficacy of photoimmunotherapy can be evaluated more accurately with an orthotopic mouse model than with a subcutaneous one. A pleural dissemination model can be used for the evaluation of treatment methods for intrathoracic diseases such as lung cancer or malignant pleural mesothelioma. Near-infrared photoimmunotherapy (NIR-PIT) is a recently developed cancer treatment strategy that combines the specificity of tumor-targeting antibodies with toxicity caused by a photoabsorber (IR700Dye) after exposure to NIR light.

Serum soluble mesothelin-related protein (SMRP) and fibulin-3 levels correlate with baseline malignant pleural mesothelioma (MPM) tumor volumes but are not useful as biomarkers of response in an immunotherapy trial.

Lung Cancer 2021 04 14;154:5-12. Epub 2021 Jan 14.

Department of Medicine, University of Pennsylvania Perelman School of Medicine, Philadelphia, PA, United States.

Objectives: Soluble mesothelin-related protein (SMRP) and fibulin-3 serum levels may serve as diagnostic and prognostic biomarkers of malignant pleural mesothelioma (MPM). Here, we evaluate these markers for correlation to tumor volume, prognosis and response assessment in a clinical trial of immunogene therapy in combination with chemotherapy.

Materials And Methods: Serial serum levels of SMRP and fibulin-3 were measured in adult patients with biopsy-proven MPM enrolled in two prospective clinical trials. Read More

Abscopal effect in a patient with malignant pleural mesothelioma treated with palliative radiotherapy and pembrolizumab.

Clin Transl Radiat Oncol 2021 Mar 1;27:85-88. Epub 2021 Jan 1.

Service of radiation oncology, Lausanne University Hospital, Rue du Bugnon, 46, CH-1011 Lausanne, Switzerland.

The abscopal effect describes the ability of locally administered radiotherapy to induce systemic antitumor effects. Although mentioned for the first time in the 1950s, records of abscopal effects, considered to be immune-mediated, are scarce with radiotherapy alone. However, with the continued development and use of immunotherapy, reports on the abscopal effect have become increasingly frequent during the last decade. Read More

Oxford Centre for Respiratory Medicine, Oxford University Hospitals NHS Foundation Trust, Oxford OX3 7LE, UK.

Pleural disease diagnostics represent a sprawling topic that has enjoyed a renaissance in recent years from humble beginnings. Whilst pleural patients are heterogeneous as a population and in the aetiology of the disease with which they present, we provide an overview of the typical diagnostic approach. Pleural fluid analysis is the cornerstone of the diagnostic pathway; however, it has many shortcomings. Read More

Nivolumab for malignant peritoneal mesothelioma.

BMJ Case Rep 2020 Nov 30;13(11). Epub 2020 Nov 30.

Medical Oncology, Okayama Rosai Hospital, Okayama, Japan

Malignant peritoneal mesothelioma (MPeM) is a highly malignant neoplasm of the peritoneum, which carries a poor prognosis. A 70-year-old man, who was employed in the shipbuilding industry and exposed to asbestos for 50 years, was found to have a low-density lesion in the peritoneum around the liver and spleen, associated with multiple mediastinal and parasternal lymphadenopathy. Laparoscopic exploration was performed, and biopsy specimen analysis led to a diagnosis of MPeM. Read More

Multicellular contractility contributes to the emergence of mesothelioma nodules.

Sci Rep 2020 11 18;10(1):20114. Epub 2020 Nov 18.

Department of Biological Physics, Eotvos University, Budapest, Hungary.

Malignant pleural mesothelioma (MPM) has an overall poor prognosis and unsatisfactory treatment options. MPM nodules, protruding into the pleural cavity may have growth and spreading dynamics distinct that of other solid tumors. We demonstrate that multicellular aggregates can develop spontaneously in the majority of tested MPM cell lines when cultured at high cell density. Read More

Primary Intrathoracic Sarcomas: A Review of Cross-sectional Imaging and Pathology.

J Comput Assist Tomogr 2020 Nov/Dec;44(6):821-832

From the Department of Radiology.

The most common sarcomas in the thorax are metastasis from an extrathoracic primary malignancy. Primary intrathoracic sarcomas are rare albeit aggressive malignancies that are diagnosed on histopathology. Although a few imaging characteristics have been described that are common to sarcomas, it is still a diagnosis of exclusion as other tumors are much more common. Read More

Virginia-Maryland College of Veterinary Medicine, 205 Duck Pond Dr, Blacksburg, VA, 24060, USA.

This report describes the transthoracic echocardiographic findings and computed tomography features of a 12-year-old West Highland white terrier with constrictive pericarditis (CP) secondary to pericardial mesothelioma. Although pericardial mesothelioma is well described in dogs, its association with CP in the canine population is not as widely reported. In this clinical case, a multidisciplinary imaging approach was helpful to identify anatomical and hemodynamic abnormalities that allowed for a diagnosis of CP. Read More
