Higher exercise tolerance early after allogeneic hematopoietic stem cell transplantation is the predictive marker for higher probability of later social reintegration

Abstract

AbstractAs the proportion of long-term survivors after allogeneic hematopoietic stem cell transplantation (allo-HSCT) is on the rise, it is essential to consider the significance of quality of life (QOL), including reintegration with society (returning to school or work). This retrospective cohort study aims to illustrate the precise epidemiology of social reintegration later after allo-HSCT and determine its predictive indicators. We enrolled 56 patients, and 40 patients (71%) attained social reintegration at 2 years post-HSCT. Reintegration failure markedly correlated with an inferior performance status and concurrent chronic graft-versus-host disease. In non-reintegrated patients, the physical function at discharge measured by the 6-min walking distance (6MWD) was markedly decreased. On the multivariate risk analyses, sex (female; odds ratio (OR) 0.07; 95% confidence interval (CI) 0.01–0.54; p = 0.01), HCT-CI (≥ 2; OR 0.10; 95% CI 0.01–0.84; p = 0.03), and change in 6MWD (per 5% increase; OR 1.47; 95% CI 1.01–2.13; p = 0.04) were significant predictors of later social reintegration. This study suggests that a multidisciplinary strategy including rehabilitation is essential, especially in patients with poor predictive markers at an early phase, and we should consider suitable rehabilitation programs to prevent a decline in exercise tolerance and improve social reintegration and overall QOL in patients after allo-HSCT.
