Abstract
BackgroundWorldwide > 50,000 hematopoietic stem cell transplants (HSCTs) are performed annually. HSCT patients receive multiple cardiotoxic therapies (chemotherapy and radiation therapy) in addition to severe physical deconditioning during hospital admission. We hypothesized that guided exercise in a cardiac rehabilitation (CR) program following autologous HSCT is a safe and feasible intervention. MethodsPilot project to assess for safety, feasibility and impact of 8 weeks of CR in HSCT patients following transplant. Consecutive patients with lymphoma underwent standard activity protocol testing before HSCT, at 6 weeks following HSCT (prior to CR), and at 14 weeks following HSCT (at completion of CR), consisting of grip strength (GS), gait speed (GtS), timed up-and-go (TUG), and 6-minute walk test (6MWT). CR consisted of 8 weekly visits for guided exercise. ResultsActivity tolerance protocol data of 30 patients (24 male, 6 female) from December 2014 to December 2016 were analyzed using repeated measures (analysis of variance [ANOVA]) to observe for changes in GS, GtS, TUG, and 6MWT. Statistically significant improvements were found in GS (P < 0.005), GtS (P = 0.02), and 6MWT (P = 0.001). These improvements show that guided CR-based exercise may assist HSCT survivors to meet or even surpass baseline exercise levels and improve physical functioning. There were no adverse events (ie, death or injury) during the study period. Fifty-seven percent of referred patients participated in CR, exceeding documented CR adherence in cardiac populations. ConclusionsThe addition of CR-based exercise programming in HSCT survivorship care of patients with lymphoma is a safe and feasible intervention to assist in recovery following transplant.
