Background:
Malignant peritoneal mesothelioma (MPeM) is a rare cancer of the mesothelial cells in the peritoneum with poor prognosis. Earlier reports from other countries indicate an incidence of 0.2-3 new cases per million per year. No previous studies have examined the national epidemiology of MPeM in Nordic countries. This study aimed to clarify the epidemiology of MPeM in Finland over a 12-year period.
Methods:
The data consisted of cancer notifications, laboratory notifications, and death certificate information in the Finnish Cancer Registry (FCR) and Statistics Finland (SF) of all MPeM patients from 2000 to 2012 in Finland. We also collected data on occupational disease compensations from the Workers' Compensation Center (WCC) of Finland. Any missing information was collected from the respective patient's file of every patient obtained from health institutions that had treated the patients.
Results:
Between January 1, 2000 and December 31, 2012, 90 new MPeM cases (56 males, 34 females) occurred in Finland. Median annual incidence was four new cases, which corresponded to 0.74 new cases per million per year. MPeM was deemed an occupational disease in 21 patients (23.3%). 71 patients (78.9%) of whom had a known cause of death, with a median survival of 4 months. The number of deaths linked to other disease than mesothelioma was 28/74 (37.8%).
Conclusions:
Our study indicates that MPeM in Finland is rare and fatal, which is in accordance with previous reports from other countries. MPeM is also a fatal disease, since most of the patients died due to MPeM.
