BACKGROUND: Clonal hematopoiesis of indeterminate potential (CHIP) is a fairly newly described phenomenon characterized by myeloid cancer-associated somatic mutations detectable in the peripheral blood of individuals without evidence of hematologic disease. Individuals with CHIP have a significantly increased risk of developing a hematologic malignancy, although the overall rate of transformation is low. OBJECTIVE: We review the current state of knowledge on causes of clonal expansion of blood cells as well as identifiable risk factors for progression to overt hematologic malignancy. RESULTS AND CONCLUSION: CHIP is considered a premalignant state and predisposes to the development of hematologic malignancy. Because the overall rate of transformation is low, clear identification and subsequent monitoring of those CHIP individuals at a higher risk is of paramount importance. In the future, prospective studies evaluating preventive and/or preemptive therapeutic strategies may aid in avoiding progression to blood cancer in individuals with CHIP.      «
