Lombardy represents the largest region of Italy by population, with almost 10 million residents, a dimension similar to a medium size country like Sweden or Belgium. The CML subcommittee of the Lombardy Hematology Network (REL‐CML) conducted a study at the beginning of 2023. Prevalence was calculated by direct input from the 21 centers participating in REL‐CML. Tyrosine Kinase Inhibitors (TKI) prescription records collected from the ARIA regional registry were used to estimate the number of CML patients followed in smaller centers not participating in REL‐CML. A total of 2285 patients were registered, representing a prevalence of 0.23 ‰. These data were compared to a similar census conducted in 2005, at the beginning of the TKI era, where a prevalence of 0.029‰ was calculated. This indicates that an almost 10 times increase took place during this period of time. Imatinib represents the most frequently prescribed first‐line TKI; its use in 2022 still represented 75% of total first line prescriptions. An increased concentration of the care of CML patients in specialized REL centers with a decreased dispersion of patients in small centers was also evident over this 18 year period of time. Nineteen % of patients discontinued treatment, highlighting persisting logistical and biological challenges; one some recommendations on CML management are included to this aim.
