Improving Outcomes in Allogeneic Transplantation and Chronic Graft-versus-Host Disease Patients through Lifestyle Medicine: Current Landscape and Future Directions.

Abstract

Although lifestyle interventions have shown promise in oncology and for cancer survivorship, their potential to improve outcomes in allogeneic hematopoietic cell transplantation (allo-HCT) and chronic graft-versus-host disease (cGVHD) patients remains to be fully explored. Given the high rates of cardiovascular disease, metabolic syndrome, and secondary malignancy in this patient population, lifestyle modifications can serve as a vital frontline defense against chronic diseases. Current research has illuminated the potential supportive role of lifestyle interventions in the solid cancer patient population, which is encouraging future lifestyle medicine research for patients with hematologic malignancies and allo-HCT recipients. Recent studies have indicated the pernicious effects of poor lifestyle choices on the course of cGVHD development and survival. The intersection between certain pillars of lifestyle medicine (ie, nutrition and exercise) and allo-HCT patient outcomes has been more well documented than that of other pillars (ie, social relationships and spirituality). Ongoing randomized trials studying the effects of exercise and nutrition on clinical outcomes in cGVHD and allo-HCT patients may provide important future evidence of the role of lifestyle medicine in this patient population. In this review, we describe the current landscape of lifestyle medicine in allo-HCT and cGVHD, its potential, and propose ways to further develop this evolving field of medicine.
