PURPOSE: Malignant pleural mesothelioma (MPM) is a rare malignancy with a dismal median survival of <12 months with current therapy. Single and combination chemotherapy regimens have shown only modest clinical benefit. In preclinical studies, nitrogen-containing bisphosphonates (zoledronic acid) inhibit growth of mesothelioma cells by different mechanisms: inhibition of mevalonate pathway, inhibition of angiogenesis, activation of apoptosis through caspase activation, and alteration in activity of matrix metalloproteinases, thereby affecting invasiveness of cancer cells...

OBJECTIVE: Due to some historical (and inaccurate) reports that asbestos might be present in some cosmetic talc products, questions are occasionally raised regarding the potential pleural mesothelioma risks associated with cosmetic talc products. Our objective was to determine the incidence of pleural mesothelioma of individuals exposed to cosmetic talc. MATERIALS AND METHODS: We conducted a systematic review of the epidemiological literature for cosmetic talc miners and millers and found three occupational cohort studies that evaluated pleural mesothelioma incidence in workers in Italy, Norway, France, and Austria...

A 68-year-old woman presented with abdominal pain, weight loss, and vomiting. Enhanced computed tomography (CT) showed slightly increased density in the mesentery and edema of the third portion of the duodenum and proximal jejunum. Little ascites, but no primary lesion, lymph node metastases, or distant metastases, were observed. Endoscopic findings included erythema and edema in the distal duodenum and proximal jejunum without epithelial lesions. Double-contrast radiography revealed transverse ridging with convergence, suggesting a serosal lesion...

Malignant mesothelioma presenting with recurrent chylous effusion is rare. We describe the case of a 34-year-old female Macedonian immigrant who presented with central chest pain and subsequently a left-sided chylous pleural effusion. The diagnosis was made on pleural biopsy via video-assisted thoracoscopic surgery (VATS). Our case demonstrates the utility of thoracic magnetic resonance imaging (MRI) and the difficulties associated with pleural cytology and cervical lymph node biopsy in the establishment of a diagnosis of mesothelioma...

We herein report two cases of malignant pleural mesothelioma with marked lymphangiosis. The patients included a 68-year-old man and a 67-year-old man who both had a history of exposure to asbestos. Computed tomography (CT) on admission showed pleural effusion with pleural thickening. In both cases, a histopathological examination of the pleura confirmed the diagnosis of epithelioid malignant mesothelioma. They received chemotherapy, but the treatment was only palliative. The chest CT assessments during admission revealed marked pleural effusion and mediastinal lymphadenopathy...

INTRODUCTION: The upregulation of PD-L1 is found in many cancers and contributes to the evasion of the host's immune defence. In malignant pleural mesothelioma (MPM), PD-L1 expression is associated with non-epithelioid histological subtype and poor prognosis, but the pathways involved in the control of PD-L1 expression in MPM are poorly understood. To address one possible means of PD-L1 regulation we investigated the relationship between dysregulated microRNA levels and PD-L1 expression...

Sulforaphane (SFN) is an isothiocyanate compound derived from glucoraphanin, which is found in cruciferous vegetables, and has been heralded as a chemopreventive and/or chemotherapeutic agent. The present study investigated the effects of SFN on enhancing the anticancer role of cisplatin (cis-dichlorodiammineplatinum; CDDP) in H‑28 malignant mesothelioma cells. At concentrations demonstrating limited toxicity in MeT‑5A normal human mesothelial cells, combination treatment with the two compounds exhibited synergistic growth‑inhibiting and apoptosis‑promoting activities, as demonstrated by a series of proapoptotic events, including reactive oxygen species accumulation, loss of mitochondrial membrane potential, upregulation of p53 expression, increased B‑cell lymphoma 2 (Bcl‑2) associated X protein/Bcl‑2 ratio, activation of caspase‑3, the occurrence of a sub‑G0/G1 peak and an increase in cells with pyknotic and fragmented nuclei, Annexin V‑phycoerythrin‑positive staining and G2/M phase‑transition delay in the cell cycle...

BACKGROUND: Because asbestos dust is considered one of the most dangerous types of dust for people's health, issues related to the effects of asbestos exposure still remain questions about the role of cessation of exposure. OBJECTIVES: The aim of the present study was to determine the importance of temporal patterns, especially the time since the end of exposure in the risk of pleural mesothelioma. METHODS: A total of 131 patients with pleural mesothelioma and 655 frequency matched by gender and year of birth controls enrolled in the health surveillance programme for asbestos-related diseases over the years 2000-2014, were included in the analysis...

BACKGROUND: Epithelioid peritoneal malignant mesothelioma (EPMM) is the most common subtype of this aggressive tumor. We compared two antibodies against PD-L1, a recent theranostic biomarker, and evaluated the prognostic value of PD-L1 expression by mesothelial and immune cells in EPMM. METHODS: Immunohistochemistry was performed on 45 EPMM. Clinical and pathological data were extracted from the RENAPE database. Using E1L3N and SP142 clones, inter-observer agreement, PD-L1 expression by mesothelial and immune cells and inter-antibody agreement were evaluated...

BACKGROUND: CD40 signalling can synergise with chemotherapy in preclinical cancer models, and early clinical studies are promising. We set out to define the immunological changes associated with this therapeutic combination to identify biomarkers for a response to the therapy. Here, we present serial immunomonitoring examining dendritic cell and T cell subpopulations over sequential courses of chemoimmunotherapy. METHODS: Fifteen patients with mesothelioma received up to six 21-day cycles of pemetrexed plus cisplatin chemotherapy and anti-CD40 (CP-870,893)...

BRCA1-associated protein 1 (BAP1) is a potent tumour suppressor gene that modulates environmental carcinogenesis. All carriers of inherited heterozygous germline BAP1-inactivating mutations (BAP1(+/-)) developed one and often several BAP1(-/-) malignancies in their lifetime, mostly malignant mesothelioma, uveal melanoma, and so on. Moreover, BAP1-acquired biallelic mutations are frequent in human cancers. BAP1 tumour suppressor activity has been attributed to its nuclear localization, where it helps to maintain genome integrity...

The separation of sarcomatoid and desmoplastic malignant mesotheliomas from sarcomatoid carcinomas of the lung metastatic to the pleura may be difficult, since both types of tumor can be morphologically similar and are frequently positive only for pan-keratin. GATA binding protein 3 (GATA3) is most commonly used as an immunohistochemical marker of breast and urothelial carcinoma, but is also known to stain other types of tumors including some mesotheliomas. In this study we asked whether GATA3 stains could be used to distinguish sarcomatoid/desmoplastic malignant mesotheliomas (N=19) from sarcomatoid carcinomas of the lung (N=13)...

Calretinin (CALB2) is a diagnostic and prognostic marker in malignant pleural mesothelioma (MPM). We previously reported that calretinin expression is regulated at the mRNA level. The presence of a medium-sized (573 nucleotide) 3' untranslated region (3'UTR) predicted to contain binding sites for miR-30a/b/c/d/e and miR-9 as well as an adenine/uridine-rich element (ARE) in all three transcripts arising from the CALB2 gene, suggests that calretinin expression is regulated via posttranscriptional mechanisms. Our aim was to investigate the role of the CALB2-3'UTR in the posttranscriptional regulation of calretinin expression in MPM...

Benign Multicystic Peritoneal Mesothelioma (BMPM) is a rare condition that arises from the abdominal peritoneum. Fewer than 200 cases have been reported worldwide. BMPM usually affects premenopausal women and is extremely rare in men. Many factors are suspected to contribute to its development, such as previous surgery, endometriosis, and familial Mediterranean fever. The main management is surgical resection; however, it is estimated that the recurrence rate is up to 50%. Malignant transformation is rare. We report a case series of three male patients who were diagnosed with BMPM and were treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC)...

How best to sequence and integrate immunotherapy into standard of care is currently unknown. Clinical protocols with accelerated non-ablative hypofractionated radiation followed by surgery could provide an opportunity to implement immune checkpoint blockade.<br /><br />Experimental Design: We therefore assessed the impact of non-ablative hypofractionated radiation on the immune system in combination with surgery in a mouse mesothelioma model. Blunt surgery (R1 resection) was used to analyze the short term impact and radical surgery (R0 resection) was used to analyze the long-term impact of this radiation protocol before surgery...
