Recently, the number of previously asbestos-exposed workers performing, at our department, medical exams aimed at an early diagnosis of asbestos-related tumors, has been progressively increasing. The diagnostical protocol we propose to these subjects include both radiological exams and some serum markers such as mesothelin and osteopontin. In this case-report we illustrate the history of a worker who, after having diagnosed a pulmonary asbestosis, developed a Lung Cancer. The significance of this case is based on the importance of the high mesothelin dosage which prompted further radiological exams resulting into the final diagnosis. In spite of the early diagnosis and treatment the patient finally died. Nevertheless, serum markers like mesothelin and osteopontin (especially the first) may result very helpful in monitoring and screening the population of workers previously exposed to asbestos.

Background: The time between initial asbestos exposure and asbestos-related disease can span several decades. The Asbestos Surveillance Program aims to detect early asbestos-related diseases in a cohort of 8,565 power industry workers formerly exposed to asbestos.
Research Question: How does asbestos exposure patterns affect cancer mortality and the duration of latency until death?
Methods: A mortality follow-up was conducted with available vital status for 8,476 participants (99 %) and available death certificates for 89.

Article Synopsis
- This study aimed to explore how different aspects of asbestos exposure relate to pleural plaques (PP) in retired workers in France.
- A large screening program conducted from 2003 to 2016 involved 5,392 participants, with HRCT scans and detailed evaluations of their work history to gauge their asbestos exposure levels.
- The findings revealed complex, non-linear relationships where the risk of PP increased with higher cumulative asbestos exposure and longer periods since first exposure, while the odds decreased with longer times since last exposure.

17-β-estradiol, involved in mesothelioma pathogenesis, and its precursors were explored as potential biomarkers for the early diagnosis of mesothelioma. Using enzyme-linked immunosorbent assay(ELISA) for 17-β-estradiol and ultra-high performance liquid chromatography/tandem mass spectrometry(UHPLC-MS/MS) for 19 17-β-estradiol precursors, a comprehensive analysis of 20steroid hormones was conducted in the serum of mesothelioma patients(n=67), asbestos-exposed healthy subjects(n=39), and non-asbestos-exposed healthy subjects(n=35). Bioinformatics analysis explored three potential serum biomarkers: 17-β-estradiol, DHEA-S, and androstenedione.

Objectives: The association between asbestos exposure and asbestosis in high-exposed industrial cohorts is well-known, but there is a lack of knowledge about the exposure-response relationship for asbestosis in a general working population setting. We examined the exposure-response relationship between occupational asbestos exposure and asbestosis in asbestos-exposed workers of the Danish general working population.
Methods: We followed all asbestos-exposed workers from 1979 to 2015 and identified incident cases of asbestosis using the Danish National Patient Register.

Article Synopsis
- Asbestos is a significant occupational carcinogen, and despite its ban in Italy since 1992, the country continues to face high rates of asbestos-related diseases (ARDs), particularly in the Province of Palermo from 2010 to 2021.
- The study identified 245 ARD cases among asbestos-exposed workers, revealing a range of conditions including asbestosis, lung cancer, and mesothelioma, with tobacco use notably increasing lung cancer risk.
- The findings highlight the ongoing public health challenge posed by ARDs, stressing the need for improved data collection and early diagnosis methods to better manage these diseases in affected populations.
