The introduction of tyrosine kinase inhibitors (TKIs) has improved the overall survival of chronic myeloid leukemia patients in chronic phase (CP-CML) and reduced the rate of disease-related mortality.

We analyzed the mortality rate of 2315 CP-CML patients treated with frontline second-generation TKIs through the Italian Medicines Agency (AIFA) registries and compared it with the ISTAT mortality rate of the general population. The estimated differences show that the increased rate of mortality in CP-CML patients is less than 1% for the class 0-29 years, stable around 2% for the intervals 30-44 years and 45-59 years, and 1.4% for the interval 60-74 years; interestingly this rate is reduced for patients aged 75 years and more as compared to the general population (- 0.65%). The difference between potential and estimated deaths is higher among women in the age classes between 30 and 74 years.

Abstract

The introduction of tyrosine kinase inhibitors (TKIs) has improved the overall survival of chronic myeloid leukemia patients in chronic phase (CP-CML) and reduced the rate of disease-related mortality. Conflicting results have been however reported between data emerged from sponsored clinical trials and from population-based registries. Moreover, no data are so far available for patients treated with frontline second-generation TKIs, excluding those from sponsored studies. We analyzed the mortality rate of 2315 CP-CML patients treated with frontline second-generation TKIs through the Italian Medicines Agency (AIFA) registries and compared it with the ISTAT mortality rate of the general population. The estimated differences show that the increased rate of mortality in CP-CML patients is less than 1% for the class 0-29 years, stable around 2% for the intervals 30-44 years and 45-59 years, and 1.4% for the interval 60-74 years; interestingly this rate is reduced for patients aged 75 years and more as compared to the general population (- 0.65%). The difference between potential and estimated deaths is higher among women in the age classes between 30 and 74 years.
