Diagnostic and prognostic value of three micrornas in environmental asbestiform fibers-associated malignant mesothelioma
2021
Fluoro-edenite (FE) is an asbestiform fiber identified in Biancavilla (Sicily, Italy). Environmental exposure to FE has been associated with a higher incidence of malignant mesothelioma (MM). The present study aimed to validate the predicted diagnostic significance of hsa-miR-323a-3p, hsa-miR-101-3p, and hsa-miR-20b-5p on a subset of MM patients exposed to FE and matched with healthy controls. For this purpose, MM tissues vs. nonmalignant pleura tissues were analyzed through droplet digital PCR (ddPCR) to evaluate differences in the expression levels of the selected miRNAs and their MM diagnostic potential. In addition, further computational analysis has been performed to establish the corr…

Factors predicting poor survival after lung-sparing radical pleurectomy of IMIG stage III malignant pleural mesothelioma.
2012
OBJECTIVES: The role of radical pleurectomy (RP) in the management of IMIG stage III in malignant pleural mesothelioma (MPM) remains controversial. The aim of the study was to investigate the feasibility and outcome as well as to determine factors predicting poor survival. METHODS: Patients having IMIG stage III MPM were identified within a prospective multimodality treatment study (RP followed by chemoradiation) between 2002 and 2010 at a single institution. Kaplan–Meier analyses, log-rank test and Cox regression analyses were used to estimate survival and to determine predictors of survival. RESULTS: A total of 78 patients (66.3 ± 2.5 years, 65 males) underwent RP followed by chemoradiati…
Zytopathologische Ergussdiagnostik in der berufsgenossenschaftlichen Begutachtung von Asbest-assoziierten malignen Mesotheliomen und Lungenkarzinomen
2014
Pleural effusion often represents the first clinical symptom of lung carcinoma and malignant mesothelioma. As pleural punctation is performed quite early in the diagnostic procedure, effusion cytology frequently gives the first evidence about the presence of tumour cells and tumor histogenesis. In this study, we report on seven cases which were evaluated in our institution for the Employers' Liability Insurance Association, based solely on cytology findings.The mean age of the seven patients with a given long-term asbestos exposure during their working life was 81.7 years. On average eight smears per patient were investigated. In addition to routine cytology, immunocytochemistry, DNA image …
Biphasic pleural mesothelioma in a electrician working in a railway company: Case report and current trends in mesotheliomas in Italy
2018
Background: Mesothelioma is an aggressive tumour that can involve the pleura, the peritoneum, and sometimes other mesothelia, such as the pericardium and the tunica vaginalis testis. Scientific communities have known for a long time the causal correlation between exposure to asbestos (work related or not) and the onset of the disease (in 75% - 90% of cases) and the increasing number of asbestos-correlated mesotheliomas expected in the next years. Case presentation: The authors present the case of an electrician, 66-year-old man, died for pleural mesothelioma, working in Palermo in the company of the Italian Railways for a period of about 20 years, exposed to asbestos. Frequently he disassem…

C1q–Ha matrix regulates the local synthesis of hyaluronan in malignant pleural mesothelioma by modulating has3 expression
2021
Increased hyaluronic acid (HA) production is often associated with cancer progression. In malignant pleural mesothelioma (MPM), HA is found at elevated levels in pleural effusions and sera of patients, and it has been widely debated whether MPM cells are able to produce HA by themselves or through the release of growth factors stimulating other cells. Another key component of the MPM microenvironment is C1q, which can act as a pro-tumorigenic factor favoring cell adhesion, migration and proliferation. The aim of the current study was to prove that MPM primary cells are able to synthesize HA and to inquire the stimulus given by C1q&ndash
Complement Protein C1q Binds to Hyaluronic Acid in the Malignant Pleural Mesothelioma Microenvironment and Promotes Tumor Growth
2017
C1q is the first recognition subcomponent of the complement classical pathway, which acts towards the clearance of pathogens and apoptotic cells. C1q is also known to modulate a range of functions of immune and non-immune cells, including their involvement in placental development and sensorial synaptic pruning. We have recently shown that C1q can promote tumour by encouraging their adhesion, migration and proliferation in addition to angiogenesis and metastasis. In this study, we have examined the role of C1q in the microenvironment of malignant pleuric mesothelioma (MPM), a rare form of cancer commonly associated with exposure to asbestos. We found that C1q was highly expressed in all MPM…
Opioid Responsiveness-Primary Diagnosis Relationship in Advanced Cancer Patients Followed At Home
2000
The aim of this study was to evaluate the influence of the primary cancer on pain characteristics and opioid response, in terms of analgesia and adverse effects, in advanced cancer patients followed at home. A prospective study was carried out in a sample of 434 consecutive advanced cancer patients who required opioids during the last four weeks of life. One hundred eighty-one patients received opioids for longer than the four weeks and were considered for this analysis. Demographic data, primary diagnosis, and pain mechanisms were recorded, and mean opioid doses, pain intensity, and symptoms were assessed at weekly intervals during the last four weeks of life. In the group of 181 patients,…
Occupational Diseases: Asbestosis and Mesothelioma in Forensic Practice
2019
Diagnosis of occupational diseases, a strong collaboration between radiologic and clinical features with related occupational history and literature supporting, and an association between the exposure and the disease process are requested. Further pathological findings emerging at biopsy or autopsy, which are considered ancillary examination techniques, may assist in the judgment related to causal chain reconstruction.
