title: Transplantation outcome in allogeneic PBSCT patients according to a new chronic GVHD grading system, including extensive skin involvement, thrombocytopenia, and progressive-type onset.
abstract: Patients who had suffered chronic GVHD after an allogeneic PBSCT were evaluated using a new chronic GVHD grading system. The study included 36 consecutive adult patients with hematological diseases, who survived at least until day 90 following allogeneic PBSCT and who could be evaluated for chronic GVHD. Extensive skin involvement was observed in five patients, thrombocytopenia in 14, and progressive-type onset in 10, while grade 1 chronic GVHD appeared in 21 patients, grade 2 in 10, and grade 3 in five. There was a significant difference in the probability of relapse between the groups with grade 1 and 2+3 chronic GVHD (55.3 vs 16.4%, P=0.0211). The difference was particularly marked in patients with high-risk hematological malignancies (grade 1 vs grade 2+3, 75 vs 0%, P=0.0115). With a median follow-up of 12 months (range, 4-52 months), 22 (66.1%) patients were still alive. The estimated 2-year survival rate for the whole population was 57.6%, while that for the group with chronic GVHD grade 1 and grade 2+3 was 53.5 and 56.3%, respectively (P=0.4387). Accordingly, there was a significant difference in the probability of relapse between the groups with grade 1 and grade 2+3 chronic GVHD.
