Abstract
Myeloid malignancies (MMs) are heterogeneous groups of diseases which present different prognoses. Using data from the population-based Girona Cancer Registry, we estimated the relative survival (RS) rates and relative excess risk of death among patients with MMs in the province of Girona between 1994 and 2008. The 5-year RS rate was 49.7%, ranging from 20.2% for acute myeloid leukemia (AML) to 75.3% for myeloproliferative neoplasms (MPN). Marked differences in RS were observed when the age of patients was considered: an increase in RS was mainly found in younger patients with myelodysplastic syndromes and MPN. Furthermore, cases of chronic myeloid leukemia treated with imatinib had a significantly better outcome compared with those that were untreated. Despite the slight improvement in the survival rate of younger patients with AML, RS remained stable for 15 years, as no significant improvements were made in the management of the disease during that period.
