Demographics

Mesotheliomas are uncommon, but not rare; 60-90 cases are diagnosed per year in British Columbia.

Incidence

Annual incidence is estimated at 1-2 per 100,000 per year. Mesothelioma is approximately five times more common in men than women. 

Age

Incidence rises with age and is approximately 10-fold higher in men between the ages of 60 and 64 years than among those between 30 and 34 years. The median age of diagnosis is 60 years, and is determined by the age at the time of asbestos exposure rather than other factors.

Survival 

Adverse prognostic factors include: poor performance status, advanced stage, leukocytosis, male gender, sarcomatoidhistology, and presence of chest pain. Median survival is 10-12 months, and two-year survival rate is 15-20%. The presence of three or more adverse prognostic factors reduces median survival to < 6 months. Median survival of stage I disease has been reported to be 16 months. A minority of cases can be indolent and associated with survival for several years, independent of treatment. However, reports of long-term disease-free survivors are anecdotal.
