ABSTRACT
Chronic graft-versus-host disease (cGVHD) is a complication of allogeneic hematopoietic stem cell transplantation (HSCT), negatively impacting quality of life (QoL) and increasing the risk of death. Complexity in cGVHD diagnosis and treatment causes significant variations in cGVHD management strategies across medical centers and physicians despite the existence of published guidelines. Thus, we hypothesized that center volume is associated with cGVHD incidence and outcomes after cGVHD develops. This study aimed to evaluate the effect of center volume on the incidence of cGVHD in patients who underwent HSCT and outcomes in patients with cGVHD. Our retrospective study included 28,786 patients who underwent their first HSCT (overall cohort) and 7664 who developed cGVHD (cGVHD cohort). We categorized institutions into quartiles (very low, low, high, and very high) using the number of HSCTs performed during the study period. We assessed cGVHD incidence in overall cohort and overall survival (OS) in cGVHD cohort. The very high-volume group showed significantly higher cGVHD incidence (adjusted hazard ratio [HR], 1.38; 95% confidence interval [CI] 1.30 to 1.46) compared to the very low-volume group. However, the cGVHD incidence was similar among very low-, low- and high-volume groups. Low, high, and very high-volume groups showed significantly higher OS with adjusted HRs of 0.83 (95% CI 0.73 to 0.94), 0.69 (95% CI 0.61 to 0.79), and 0.68 (95% CI 0.60 to 0.76), respectively, compared with the very low-volume group. In conclusion, we revealed a higher incidence of cGVHD in the very high-volume group and a poor survival outcome in the very low-volume group in patients with cGVHD.
