Asbestos-Related Lung Cancer (ARLC) presents ongoing diagnostic challenges despite improved imaging technologies. The long latency period, coupled with limited access to occupational and environmental data along with the confounding effects of smoking and other carcinogens adds complexity to the diagnostic process. Compounding these challenges is the absence of a specific histopathologic or mutational signature of ARLC.

April 2024

From the Department of Diagnostic and Interventional Radiology, Nara Medical University, 840 Shijo-cho, Kashihara-city, Nara 634-8522, Japan (A.Y., R.T., T.I., A.M., S.Y., K.M., T.T.); Department of Radiology, Nara Prefecture General Medical Center, Nara, Japan (Y.N.); Division of Diagnostic Imaging, Department of Interventional Radiology, University of Texas MD Anderson Cancer Center, Houston, Tex (K.M.); and Department of Radiology, Osaka University Graduate School of Medicine, Osaka, Japan (M.Y., N.T.).

The pleura is a thin, smooth, soft-tissue structure that lines the pleural cavity and separates the lungs from the chest wall, consisting of the visceral and parietal pleurae and physiologic pleural fluid. There is a broad spectrum of normal variations and abnormalities in the pleura, including pneumothorax, pleural effusion, and pleural thickening. Pneumothorax is associated with pulmonary diseases and is caused by iatrogenic or traumatic factors.

Background: Previous studies have inconsistently reported associations between refractory ceramic fibers (RCFs) or mineral wool fibers (MWFs) and the presence of pleural plaques. All these studies were based on chest radiographs, known to be associated with a poor sensitivity for the diagnosis of pleural plaques.

Research Question: Does the risk of pleural plaques increase with cumulative exposure to RCFs, MWFs, and silica? If the risk does increase, do these dose-response relationships depend on the co-exposure to asbestos or, conversely, are the dose-response relationships for asbestos modified by co-exposure to RCFs, MWFs, and silica?

Study Design And Methods: Volunteer workers were invited to participate in a CT scan screening program for asbestos-related diseases in France.

Asbestos-associated pulmonary disease.

Curr Opin Pulm Med

March 2023

Division of Pulmonary and Critical Care Medicine, University of Arkansas for Medical Sciences, Little Rock, Arkansas, USA.

Purpose Of Review: Exposure to asbestos can cause both benign and malignant, pulmonary and pleural diseases. In the current era of low asbestos exposure, it is critical to be aware of complications from asbestos exposure; as they often arise after decades of exposure, asbestos-related pulmonary complications include asbestosis, pleural plaques, diffuse pleural thickening, benign asbestos-related pleural effusions and malignant pleural mesothelioma.

Recent Findings: Multiple recent studies are featured in this review, including a study evaluating imaging characteristics of asbestos with other fibrotic lung diseases, a study that quantified pleural plaques on computed tomography imaging and its impact on pulmonary function, a study that examined the risk of lung cancer with pleural plaques among two large cohorts and a review of nonasbestos causes of malignant mesothelioma.

Background: Even almost 30 years after the ban on the use of asbestos in Germany, the effects of asbestos are still highly relevant in everyday clinical practice in occupational medicine. The aim of this study was to further investigate the significance of essential parameters of both pulmonary function diagnostics and imaging techniques (low-dose HR-TCT) for the prevention and early detection of asbestos-related morphological and functional lung changes.

Methods: Data from spirometry, body plethysmography and diffusion capacity, as well as CT images of the thorax, were retrospectively studied from 72 patients examined between 2017 and 2019 at the Institute for Occupational and Maritime Medicine (ZfAM), Hamburg, Germany.

The requirement for compensation for diffuse pleural thickening in benign asbestos pleural effusion include five computed tomography findings of organized pleural effusion: [1] heterogeneity in the pleural effusion, [2] declined chest capacity, [3] "crow's feet" sign at the pleura, [4] immobilization of effusion volume, and [5] air in the effusion. Pleural effusion is diagnosed as organized, immobilized, and in the state of diffuse pleural thickening if at least three of these items are fulfilled, ([1] and [3] compulsory + one of the remaining items). This retrospective study investigated whether the requirement to confirm no organized pleural effusion changes after a follow-up of >3 months were available for cases fulfilling three of the five items; i.

We describe a 78-year-old initially presenting with left breast cancer, status post mastectomy and bilateral dual-lumen breast implant placement, subsequently developed lung cancer years later status post lobectomy, who later developed FDG-avid pleural nodularity and thickening. The differential diagnosis of pleural thickening and nodularity can be broad, including metastatic cancer, asbestos-related pleural disease, loculated fluid (including simple pleural effusion, hemothorax, or chylothorax), and pleural infection. However, in the setting of two different primary malignancies, our patient's FGD-avid pleural thickening was concerning for metastatic disease.

Article Synopsis
  • A 19-year-old exchange student from Thailand showed lung issues after previous TB treatments, leading to further examinations due to a lung shadow; tests for acid-fast bacteria were negative.
  • High levels of IgE and specific antibodies indicated possible allergic bronchopulmonary aspergillosis (ABPA), confirmed after bronchoscopy revealed inflammation and yellow sputum with Aspergillus fumigatus.
  • Despite not meeting all ABPA diagnostic criteria, treatment with steroids and itraconazole improved the patient's condition, showcasing the need for accurate diagnoses as symptoms of TB and ABPA can be similar, and past medical histories may not provide a complete picture.
