How I conduct a comprehensive chronic graft-versus-host disease assessment

Since the National Institutes of Health Chronic Graft-Versus-Host Disease (cGVHD) Consensus Project in 2005, a need has emerged to evaluate cGVHD more methodically, not only to make a cGVHD diagnosis, but also to accurately classify individual organ and global organ severity, at baseline and in follow-up so that subjects participating in clinical trials may reliably be assigned an accurate response category irrespective of the evaluator. Even for patients not enrolled on a clinical trial, periodic complete cGVHD assessments can allow subtle manifestations to be detected, monitored carefully, and/or treated early with the goal of hopefully avoiding progression to highly morbid, difficult to treat, and quite often irreversible forms of cGVHD
