Have we made progress in the management of chronic graft-vs-host disease?

Chronic graft-vs-host disease (GVHD) is a common long-term complication of allogeneic hematopoietic cell transplant that is associated with very high morbidity and mortality. In order to understand whether we have made progress in the management of chronic GVHD, it is helpful to first propose a definition of meaningful "progress". The following can be considered to be indicators of improved management of chronic GVHD: a decrease in the incidence or severity of chronic GVHD, better efficacy or decreased toxicity of therapies, better quality of life despite chronic GVHD, and improved overall and disease-free survival rates. However, to date, real progress has not been made in these areas, though there are promising new preventive strategies and treatments. Furthermore, a consensus has been reached in the research community about many different issues surrounding chronic GVHD definitions, management, and the conduct of clinical trials. These consensus documents will help to standardize efforts and data collection so that true comparisons can be made in the future and real clinical progress achieved.
