Recovery of physical function, muscle mass, and quality of life in patients undergoing allogeneic hematopoietic stem cell transplantation.

This study aimed to investigate the recovery of physical function, muscle mass, and quality of life (QOL) in allogeneic hematopoietic stem cell transplantation (allo-HSCT) patients 1 year after the procedure. A total of 71 patients who underwent allo-HSCT at our institution between February 2010 and June 2020, for whom a physical therapy assessment could be performed before allo-HSCT, at discharge, and 1 year after the procedure, were included. Exercise therapy during hospitalization was provided individually by a physical therapist, and exercise was self-administered after discharge. One year after allo-HSCT, handgrip strength and results of the 6-minute walk test recovered to pre-HSCT levels. However, muscle mass 1 year after allo-HSCT did not reach the pre-HSCT level. All subscales of QOL, 1 year after allo-HSCT, recovered to pre-HSCT levels, but only two of the eight subscales recovered to the national standard of 50. Multivariate analysis revealed factors associated with the recovery of physical function, muscle mass, and QOL, hemoglobin levels and albumin levels, especially among men. In contrast, factors that negatively affected recovery were age, acute graft-versus-host disease, and pre-HSCT intensity conditioning. The results suggest a potential recovery in handgrip strength, endurance, and QOL 1 year after allo-HSCT.
