Malignant pleural mesothelioma is almost exclusively caused by exposure to asbestos dust. Recent epidemiological studies have suggested that the national incidence of disease may continue to rise until 2020 and that asbestos exposure in the building trade may be replacing shipyard related exposure as the main source of disease. The objective of the study was to determine if the incidence of malignant pleural mesothelioma was rising in the west of Glasgow from 1987–1992 and whether there had been a change in clinical features compared to previous studies from the same population. Case notes identified from coded returns and the local cancer registry were retrospectively examined: 144 cases were identified. This is an increase in incidence of over 50% compared to the previous study but the yearly incidence did not rise over the period studied. The clinical features and survival times have not changed since previous studies: median survival remains 30 weeks. Only three patients were given definitive treatment reflecting the lack of effective therapy. We suggest that the incidence of mesothelioma in the population studied may already have peaked resulting from the decline in the local shipyard industry over 20 years ago. Non-shipyard sources of asbestos exposure may be less important in this area.

Background. Abnormality of genes including 9p21 is known in malignant mesothelioma and we have examined the frequency of gene deletion and amplification using the fluorescence in situ hybridization (FISH) method. We formerly reported that abnormality of the genes was more common in the sarcomatoid type than epithelioid type. In this study, we compared the clinicopathological factors including nuclear grade (NG) and genomic abnormality in epithelioid malignant pleural mesothelioma (MPM). Methods. Using paraffin-embedded tissues of 31 epithelioid MPMs, we investigated the presence of gene abnormalities in the genes 9p21, 1p36, 14q32, 22q12, 5p15, 6p, 8q24, and 7p12 by the FISH method, and compared the results with NG, clinical stage, and prognosis. Results. In the higher NG group of epithelioid MPM, more gene amplifications [in particular 5p15 and 8q24(MYC)] were observed, and clinical stage was more advanced. Cases with the amplification of 7p12(EGFR) tended to exhibit a worse prognosis. The significant correlation between histological differentiation and clinical features such as prognosis was not confirmed. Conclusions. NG status in epithelioid MPM may be related to gene alteration and clinical features.
