Overview
Chronic Myeloid Leukemia (CML) is a myeloproliferative neoplasm with an incidence of 1–2 cases per 100,000 adults, and accounts for 15%
of newly diagnosed cases of leukemia in adults. PMID:24729196
Its incidence is 2 per 100 000/year. The peak age for the disease is 50 to 55.PMID:20221270
Published data on the annual incidence of CML varies from as low as 0.4/100,000 persons in some non-Western countries to 1.75/100,000 in the USA [7, 8, 9, 15, 16, 17, 18, 19]. As the incidence of CML increases by age, some of these variations are due to significant differences in the age distributions of the investigated populations (e.g. Western vs several non-Western countries). However, also figures on age-adjusted incidence vary considerably (0.7–1.8/100,000) between different studies.
The incidence in CML increases by age, at least up to 75–80 years (Fig. 1). In Europe, the median age at diagnosis of CML, as estimated from population-based registries, is 57–60 years (Table 1) [9, 20]. Importantly, this is about 10 years above the median age typically seen in clinical trials [19]. In children, CML is a very rare disease with an incidence of 0.6–1.2 million children/year [26].
CML is more common in males than in females with male-to-female ratio varying between 1.2 and 1.7 in different studies [8, 20, 27]. The gender difference in incidence is less prominent in younger age groups.PMID:25814090
