What is the life expectancy of dermatomyositis?

Objectives: To assess the long-term prognosis of dermatomyositis and pol myositis. Methods: 69 patients with dermatomyositis or polymyositis were selected according to the diagnostic criteria of Bohan and Peter and were followed up for a minimum of 6.3 years (for surviving patients) (mean 11.6 years).

Since then, numerous studies have shown the high cancer incidence among patients with idiopathic inflammatory myopathy, especially DM. DM with coexistent malignancy ranges from 6% to 60% of all the DM cases. Five-year survival of adult DM patients is 60% to 90%, and malignancy is the primary cause of death.
