Abstract: BACKGROUND: New criteria for the diagnosis and classification of chronic graft-versus-host disease were developed in 2005 for the purpose of clinical trials with a consensus sponsored by the National Institute of Health. OBJECTIVES: The aim of this study is to present the results of a multicenter pilot study performed by the Brazil-Seattle chronic graft-versus-host disease consortium to determine the feasibility of using these criteria in five Brazilian centers. METHODS: The study was performed after translation of the consensus criteria into Portuguese and training. A total of 34 patients with National Institute of Health chronic graft-versus-host disease were enrolled in the pilot study between June 2006 and May 2009. RESULTS: Of the 34 patients, 26 (76%) met the criteria of overlap syndrome and eight (24%) the classic subcategory. The overall severity of disease was moderate in 21 (62%) and severe in 13 (38%) patients. The median time from transplant to onset of chronic graft-versus-host disease was 5.9 months (Range: 3 - 16 months); the median time for the overlap syndrome subcategory was 5.9 months (Range: 3 - 10 months) and for the classic subcategory, it was 7.3 months (Range: 3 - 16 months). At a median follow up of 16.5 months (Range: 4 - 39 months), overall survival was 75%. CONCLUSIONS: It was feasible to use the National Institute of Health consensus criteria for the diagnosis and scoring of chronic graft-versus-host disease in a Brazilian prospective multicenter study. More importantly, a collaborative hematopoietic cell transplantation network was established in Brazil offering new opportunities for future clinical trials in chronic graft-versus-host disease and in other areas of research involving hematopoietic stem cell transplantation.
