Epidemiology of multiple myeloma in Taiwan, a population based study

Abstract Background Although the incidence of multiple myeloma (MM) in Asia is lower than in Western countries, it is steadily increasing. However, limited data are available that describe the epidemiology of MM in Asia. Methods We conducted a retrospective cohort study using the Taiwan National Healthcare Insurance Research database to estimate the disease burden and clinical characteristics of patients with MM in Taiwan. All newly diagnosed confirmed MM patients during 2007–2012 were enrolled. Patients were followed up until death or end of the observation period (December 31, 2013), whichever occurred first. Results A total of 2723 newly diagnosed MM patients were included in the cohort analysis, of whom 58.0% (1578/2723) were men. The average age of MM patients was 67.6 years. At the time of diagnosis, the mean Charlson Comorbidity Index was 1.8, 35.3% of patients had anemia, 18.0% had bone fracture, 16.4% had renal disease and 17.3% had pneumonia. The crude annual incidence of newly diagnosed MM increased from 1.74 per 100 000 population in 2007 to 2.27 per 100 000 population in 2012 (p  Conclusion The age-adjusted incidence of MM in Taiwan increased by 13% between 2007 and 2012. Despite the introduction of new treatments, MM remains largely incurable with 19.4% mortality.
