EnglishIt has been reported that chronic graft-versus-host disease (cGVHD) is associated with significant morbidity and mortality after allogeneic stem cell transplantation (allo-SCT). The risk of relapse is generally reduced when cGVHD is present, but prognosis may be affected by increased toxicity and/or risk of infection associated with immunosuppressive treatment (IST). We performed a longitudinal data analysis of cGVHD, including the evolution of cGVHD itself over time in response to IST, in a single-center cohort of 313 consecutive patients undergoing allo-SCT. We found that lack of sustained response without withdrawal of IST within 6 months of cGVHD development was associated with higher transplantation-related mortality (hazard ratio, 2.32; 95% confidence interval, 1.24-4.33) compared with cGVHD-free patients. Conversely, response conferred better overall survival (hazard ratio, 0.42; 95% confidence interval, 0.18-0.95). Our analytical approach allowed us to integrate the evolution of cGVHD in a predictive model of transplantation outcome; notably, remission associated with permanent discontinuation of IST within the first 6 months from the occurrence of cGVHD seemed to correlate most closely with final outcome. Further confirmation from larger studies is needed.

| Abstract: | It has been reported that chronic graft-versus-host disease (cGVHD) is associated with significant morbidity and mortality after allogeneic stem cell transplantation (allo-SCT). The risk of relapse is generally reduced when cGVHD is present, but prognosis may be affected by increased toxicity and/or risk of infection associated with immunosuppressive treatment (IST). We performed a longitudinal data analysis of cGVHD, including the evolution of cGVHD itself over time in response to IST, in a single-center cohort of 313 consecutive patients undergoing allo-SCT. We found that lack of sustained response without withdrawal of IST within 6 months of cGVHD development was associated with higher transplantation-related mortality (hazard ratio, 2.32; 95% confidence interval, 1.24-4.33) compared with cGVHD-free patients. Conversely, response conferred better overall survival (hazard ratio, 0.42; 95% confidence interval, 0.18-0.95). Our analytical approach allowed us to integrate the evolution of cGVHD in a predictive model of transplantation outcome; notably, remission associated with permanent discontinuation of IST within the first 6 months from the occurrence of cGVHD seemed to correlate most closely with final outcome.
