At the ADSS Symposium on 17 October 2018, Dr. Richard Slaughter, a radiologist, gave a presentation on the role of imaging in asbestos-related diseases. He described how inhaled asbestos fibers cause damage and scarring in the lungs and pleura, and discussed conditions such as pleural plaques, asbestosis, rounded atelectasis, and mesothelioma. Slaughter stated that pleural plaques are benign and serve as a marker of asbestos exposure, not a measure of it, and that while plaques themselves do not progress to cancer, they indicate significant exposure that raises the risk of mesothelioma. He noted that mesothelioma usually presents with symptoms like pain and pleural fluid, and that regular CT screening in asymptomatic patients has not been helpful for early detection. Slaughter also addressed occupational lung disease screening, stating that chest radiographs remain appropriate in remote mining towns where CT scanners and radiologists are unavailable. He commented on black lung disease in Queensland, attributing past monitoring failures to neglect and lack of proper case storage and expertise, but said a new process is now in place. He described black lung disease as preventable and called it a tragedy that anyone has silicosis or coal workers' pneumoconiosis. Slaughter also noted that there is evidence linking asbestos exposure to kidney cancer, esophageal cancer, and laryngeal cancer, and that such cases have been accepted for workers' compensation in highly exposed individuals.
“Pleural plaques are benign; they usually don't cause problems and are regarded more as a marker of asbestos exposure than a measure of asbestos exposure. Many people live with pleural plaques without even knowing it.”
“Mesothelioma is a cancer of the pleura that usually presents with weight loss or pain, and pleural effusion is the important sign on chest radiograph. It starts in the parietal pleura, not the visceral pleura.”
“Pleural plaques themselves don't progress to cancer, but people with pleural plaques have a higher chance of getting mesothelioma because plaques show significant asbestos exposure.”
“Regular CT scans to detect mesothelioma in asymptomatic patients have not been helpful; mesothelioma usually presents with symptoms like pleural fluid causing pain, so early detection by screening is rare.”
“There was an error in the monitoring of black lung disease in Queensland due to neglect and lack of proper case storage and expertise, but a new process is now in place which should improve detection and management.”
“Black lung disease is preventable, and it is a tragedy that anyone has silicosis or coal workers pneumoconiosis; every step must be taken to prevent it.”
“Chest radiographs remain appropriate for screening occupational lung disease in remote mining towns where CT scanners and qualified radiologists are not available.”
“In Australia, the problem with detecting black lung disease is not the capability of radiologists but the lack of compulsory screening programs, unlike the US where screening is voluntary and miners may avoid detection to keep bonuses.”
“There is evidence linking asbestos exposure with kidney cancer, esophageal cancer, and particularly laryngeal cancer, which are accepted for workers compensation in highly exposed people.”
