Feasibility and Safety of Exercise in Patients With Low-risk Myeloid Cancers and Precursor Conditions

Somatic mutations as seen in myeloid malignancies can also be detected in healthy, elderly individuals (clonal hematopoiesis of indeterminate potential, CHIP), in patients with unex-plained cytopenia, that do not fulfill the criteria for myeloid malignancy (clonal cytopenia of un-determined significance, CCUS) It has been shown that these conditions predispose to hema-tological cancer. For patients with CCUS, it has been reported that in a 5-year period up to 50-90 % of the patients will progress to myelodysplastic syndrome (MDS) or acute myeloid leu-kemia (AML), both devastating diseases with poor outcomes, especially for the elderly popula-tion. There is currently no treatment available for patients with CCUS besides supporting agents. Since the somatic mutations can be detected up to 10 years before a diagnosis of MDS, it opens the potential for early intervention. Physical inactivity is associated with multiple solid cancers, and it has been suggested that exercise can prevent for example certain colon- or breast cancers. Studies in mice have shown that exercise can reduce tumor size and incidence of solid cancers, and different mechanisms have been suggested including increased immune cell infiltration, reduced systemic inflamma-tion, and metabolic changes. The mechanisms of disease progression of pre-leukemia and MDS are complex and probably multifactorial, but recent studies suggest that components such as natural killer cells, adipocytes, and inflammatory substances …
