Background The 2005 National Institute of Health Chronic Graft-versus-Host Disease Consensus Conference recommended collection of patient-reported outcomes in clinical trials on chronic graft-versus-host disease. We assessed whether changes in chronic graft-versus-host disease severity, determined using National Institute of Health criteria, clinicians’ assessment or patients’ self-evaluation, correlated with patient-reported quality of life as measured by the Short Form-36 and Functional Assessment of Cancer Therapy – Bone Marrow Transplant (FACT-BMT) instruments.Design and Methods Three-hundred and thirty-six adult patients (median age 52 years; range, 19 – 79) with chronic graft-versus-host disease from six transplant centers contributed baseline and follow-up data (from 936 visits overall).Results While the majority of the patients had stable chronic graft-versus-host disease, improvement or worsening was noted in approximately 40% of follow-up visits. Multivariable analysis demonstrated no association between change in chronic graft-versus-host disease severity evaluated by National Institute of Health criteria and change in quality of life, while clinician-reported changes in severity were associated with changes in some quality of life measures. Patient-reported changes in the severity of chronic graft-versus-host disease were associated with changes in all quality of life measures. Comparison of the Short Form-36 and the FACT-BMT suggested that the data collected in the Functional Assessment of Cancer Therapy – General (FACT-G) core survey are sufficient without the need for the Short Form-36 or the FACT–BMT subscale.Conclusions We conclude that serial National Institute of Health and clinician-reported chronic graft-versus-host disease severity assessments cannot substitute for patient-reported outcomes in clinical trials. Collection of just the FACT-G instead of the Short Form-36 and the full FACT-BMT will decrease respondent burden without compromising quality of life assessment.
