Abstract

Background: Malignant pleural mesothelioma (MPM) is a rare occupational cancer with a poor prognosis. Even with a multimodality treatment approach, the treatment outcomes remain unsatisfactory. The use of asbestos has been banned in most developed countries, but MPM continues to be a significant occupational disease also in these countries. Aim of this study is to identify modern epidemiology and assess equality in care.Methods: Our study cohort consists of 1010 patients diagnosed with MPM in Finland during 2000-2012. The data were collected from the Finnish Cancer Registry, the National Workers' Compensation Center Registry and the National Registry of Causes of Death, Statistics Finland.Results: Women were diagnosed a mean of 4.5 years later than males (p=.001), but survival did not differ (overall median survival 9.7 months). A workers' compensation claim was more common in males (OR 11.0 [95% CI 7.5-16.2]) and in regions with a major asbestos industry (OR 1.7 [95% CI 1.3-2.2]). One-year and three-year survivals did not differ regionally. Patients without chemotherapy treatment had an inferior survival (RR 1.8 [95% CI 1.5-2.0]). The initial survival benefit gained with pemetrexed was diluted at 51 months.Conclusions: MPM is a disease with a poor prognosis, although chemotherapy appears to improve survival time. Significant gender and regional variation exists among patients, with notable differences in diagnostic and treatment practices. Long-term outcomes with pemetrexed remain indeterminate.Impact: Emphasize centralized consult services for the diagnosis, treatment and support that patients receive for MPM, facilitating equal outcomes and compensation.
