Sarcopenia, Precardial Adipose Tissue and High Tumor Volume as Outcome Predictors in Surgically Treated Pleural Mesothelioma
Diagnostics (Basel) 2022 January 3 [Link] Oliver Guido Verhoek, Lisa Jungblut, Olivia Lauk, Christian Blüthgen, Isabelle Opitz, Thomas Frauenfelder, Katharina Martini Abstract Background: We evaluated the prognostic value of Sarcopenia, low precardial adipose-tissue (PAT), and high tumor-volume in the outcome of surgically-treated pleural mesothelioma (PM). Methods: From 2005 to 2020, consecutive surgically-treated PM-patients having a…

Pathology International 2021 December 29 [Link] Yasumasa Okazaki Abstract Asbestos fibers have been used as an industrial and construction material worldwide due to their high durability and low production cost. Commercial usage of asbestos is currently prohibited in Japan; however, the risk of asbestos-induced malignant mesothelioma (MM) remains. According to epidemiological data, the onset of…

Molecular Cancer Research 2021 September 30 [Link] Aditya Wirawan, Ken Tajima, Fumiyuki Takahashi, Yoichiro Mitsuishi, Wira Winardi, Moulid Hidayat, Daisuke Hayakawa, Naohisa Matsumoto, Kenta Izumi, Tetsuhiko Asao, Ryo Ko, Naoko Shimada, Kazuya Takamochi, Kenji Suzuki, Masaaki Abe, Okio Hino, Yoshitaka Sekido, Kazuhisa Takahashi Abstract Malignant pleural mesothelioma (MPM) is a highly aggressive tumor that has…
Read MoreMolecular characterization of pleomorphic mesothelioma: a multi-institutional study
Modern Pathology 2021 September 16 [Link] Somak Roy, Françoise Galateau-Sallé, Nolwenn Le Stang, Andrew Churg, Maureen A Lyons, Richard Attanoos, Sanja Dacic Abstract The molecular alterations of pleomorphic mesotheliomas are largely unknown. In the present study, we performed whole-exome sequencing (WES) on 24 pleomorphic mesotheliomas in order to better characterize the molecular profile of this…
Read MoreMalignant peritoneal mesothelioma: correlation between CT imaging features and histologic subtypes
Abdominal Radiology 2021 August 3 [Link] Isha D Atre, Gaurav V Watane, Mukesh G Harisinghani Abstract Purpose: To identify correlation between CT imaging features and histologic subtypes of Malignant Peritoneal Mesothelioma (MPM). Methods: This was a retrospective single-center study of 51 consecutive patients with the diagnosis of Malignant Peritoneal Mesothelioma (MPM). The tumors were classified…
Read MoreSignificance of p53 immunostaining in mesothelial proliferations and correlation with TP53 mutation status
Modern Pathology 2021 September 8 [Link] Julia R Naso, Basile Tessier-Cloutier, Janine Senz, David G Huntsman, Andrew Churg Abstract p53 immunohistochemistry has long been proposed for the separation of benign from malignant mesothelial proliferations, with the older literature suggesting that any degree of positivity supported a diagnosis of mesothelioma. However, using modern immunohistochemistry platforms in…
