Objectives Pleural mesothelioma is a rare respiratory cancer, mainly caused by inhalation of asbestos fibres. Other inorganic fibres are also suggested risk factors. We aimed to investigate the association between exposure to asbestos or refractory ceramic fibres (RCFs) and pleural mesothelioma among male Norwegian offshore petroleum workers. Methods Among 25 347 men in the Norwegian Offshore Petroleum Workers (NOPW) cohort (1965–1998), 43 pleural mesothelioma cases were identified through the Cancer Registry of Norway (1999–2022). A case–cohort study was conducted with 2095 randomly drawn non-cases from the cohort. Asbestos and RCF exposures were assessed with expert-made job-exposure matrices (JEMs). Weighted Cox regression was used to estimate HRs and 95% CIs, adjusted for age at baseline and pre-offshore employment with likely asbestos exposure. Results An increased risk of pleural mesothelioma was indicated for the highest versus lowest tertile of average intensity of asbestos (HR=1.21, 95% CI: 0.57 to Exposure to fibres and risk of pleural mesothelioma in the Norwegian Offshore Petroleum Workers cohort
