Tissue burden evaluation of elongated mineral particles in two individuals with mesothelioma and whose work history included manufacturing tile.

Tissue burden evaluation of elongated mineral particles in two individuals with mesothelioma and whose work history included manufacturing tile. Ultrastruct Pathol. 2020 Jan 09;:1-15 Authors: Dodson RF, Poye LW Abstract Two cases with diagnosis of mesothelioma were referred to our laboratories with a request for tissue burden analysis in order to determine the presence of ferruginous bodies and uncoated elongated mineral particles in tissue samples. The individuals shared in common a past background of working in tile manufacturing facilities where industrial talc was used in the production of the products. Both were found to have ferruginous bodies in their lung tissues as well as elongated talc fibers/ribbons and elevated numbers of noncommercial amphiboles in their tissues. To our knowledge, this is the first report of tissue assessment for the presence of elongated mineral particles in individuals whose exposures to talc occurred were while working in the manufacture of tile products and who developed the fiber-related cancer - mesothelioma.

Cellular Analytics, a biotechnology company in Ontario, Canada, has unveiled a novel liquid biopsy test for mesothelioma that could lead to more effective management of this rare cancer. The test has the potential to produce a much-earlier diagnosis of disease and the ability to personalize treatment and better predict a patient’s response to specific therapies. “We could change completely how this disease is viewed,” Dr. Brent Zanke, a specialist in diagnostic oncology and chief executive officer of Cellular Analytics, told The Mesothelioma Center at Asbestos.com. “It’s a proactive way to get...

Gene therapy is moving closer to becoming part of standard-of-care treatment for pleural mesothelioma, according to the latest multicenter clinical trial. The phase III trial, known as the INFINITE clinical research study, is designed to evaluate the intrapleural delivery of an investigational drug — a type of gene therapy — in combination with celecoxib and gemcitabine, anti-inflammatory and chemotherapy drugs, respectively. Researchers hope to stop, or at least slow, the growth of mesothelioma tumor cells with the combination therapy. “This is a very interesting concept,” oncologist Dr. Bernardo G...

Malignant pleural mesothelioma (MPM) is a rare, aggressive tumor originating from mesothelial cells. It is associated with exposure to asbestos, mainly occupational, rarely environmental or domestic. Diagnosis is usually made at an advanced stage because symptoms are non-specific and late. The management of this tumor is challenging and outcome is poor. Therapeutic strategies are mainly based on surgery with curative intent or palliative cytotoxic chemotherapy. Few patients are candidates for surgery which must necessarily take into account numerous factors (i.e.

The U.S. Food and Drug Administration has granted final approval of Pemfexy, a new brand of the chemotherapy drug pemetrexed, to combat malignant mesothelioma and advanced stage non-small cell lung cancer. The approval will allow oncologists to offer an alternative to Alimta, which today is considered standard pemetrexed and manufactured by Eli Lilly and Company. The chemotherapy drug is designed to block DNA replication and cell division. However, Pemfexy will not be available until February 2022. The FDA approval is limited to pleural mesothelioma patients whose disease is unresectable. Pemfexy is produced by Eagle Pharm...

Rodent models of malignant mesothelioma help facilitate the understanding of the biology of this highly lethal cancer and to develop and test new interventions. Introducing the same genetic lesions as found in human mesothelioma in mice results in tumors that show close resemblance with the human disease counterpart. This includes the extensive inflammatory responses that characterize human malignant mesothelioma. The relatively fast development of mesothelioma in mice when the appropriate combination of lesions is introduced, with or without exposure to asbestos, make the autochthonous models particularly useful for testi...

CONCLUSIONS: The pPCI strongly differs from the sPCI for patients undergoing CRS for peritoneal disease and may provide a more accurate evaluation of the peritoneal disease extent. Further studies are needed to determine its prognostic value compared with sPCI, and consensus guidelines are needed for calculating it. PMID: 32040698 [PubMed - as supplied by publisher]
