Abstract In this study, malignant pleural mesothelioma cases in hospitals located in a region of Japan were evaluated. A total of 106 patients (97 men, 9 women) aged between 41 and 87 years were examined, of whom 100 had occupational exposure to asbestos. There were 37 cases of epithelial, 25 biphasic and 15 sarcomatous tumours. In the remaining 23 cases, it was not possible to characterize the tumour. The mean survival rate for all cases was 9.2 months. 51 had occupational histories of shipyard work, 16 patients worked in asbestos cement piping, and the remainder were employed in miscellaneous jobs involving asbestos exposure. The mean duration of asbestos exposure was 17.2 years and the average latent period for the occurrence of malignant pleural mesothelioma was 37.0 years. 94% of malignant pleural mesothelioma were due to exposure to crocidolite and amosite, with the remainder due to chrysotile.
