    • Chronic graft-versus-host disease (cGVHD) remains a major cause of morbidity and mortality after allogeneic hematopoietic stem cell transplantation (HSCT). Aim is to identify risk factors for the development of cGVHD in a multicenter setting. Patients transplanted between 2000 and 2006 were analyzed (n = 820). Donors were HLA-identical siblings (57%), matched unrelated donors (30%), and HLA-A, B or DR antigen mismatched (13%). Reduced intensity conditioning (RIC) was given to 65% of patients. Overall incidence of cGVHD was 46% for patients surviving more than 100 days after HSCT (n = 747). Older patient age [HR 1.15, p < 0.001], prior acute GVHD [1.30, p = 0.024], and RIC [1.36, p = 0.028] increased overall cGVHD. In addition, RIC [4.85, p < 0.001], prior aGVHD [2.14, p = 0.001] and female donor to male recipient [1.80, p = 0.008] increased the risk of severe cGVHD. ATG had a protective effect for both overall [0.41, p < 0.001] and severe cGVHD [0.20, p < 0.001]. Relapse-free survival (RFS) was impaired in patients with severe cGVHD. RIC, prior aGVHD, and female-to-male donation increase the risk of severe cGVHD. ATG reduces the risk of all grades of cGVHD without hampering RFS. GVHD prophylaxis may be tailored according to the risk profile of patients.

  • Evaluation of prognostic factors among patients with chronic graft-versus-host disease
  • 2012
  • Ingår i: Haematologica. - : Ferrata Storti Foundation (Haematologica). - 0390-6078 .- 1592-8721. ; 97:8, s. 1187-1195

    • BACKGROUND:Chronic graft-versus-host disease (cGVHD) is a major complication after allogeneic stem cell transplantation with an adverse effect on both mortality and morbidity. In 2005, the National Institute of Health proposed new criteria for diagnosis and classification of chronic graft-versus-host disease for clinical trials. New sub-categories were recognized such as late onset acute graft-versus-host disease and overlap syndrome.DESIGN AND METHODS:We evaluated the prognostic impact of the new sub-categories as well as the clinical scoring system proposed by the National Institute of Health in a retrospective, multicenter study of 820 patients undergoing allogeneic stem cell transplantation between 2000 and 2006 at 3 different institutions. Patients were retrospectively categorized according to the National Institute of Health criteria from patients' medical histories.RESULTS:As far as the new sub-categories are concerned, in univariate analysis diagnosis of overlap syndrome adversely affected the outcome. Also, the number of organs involved for a cut-off value of 4 significantly influenced both cGVHD related mortality and survival. In multivariate analysis, in addition to NIH score, platelet count and performance score at the time of cGVHD diagnosis, plus gut involvement, significantly influenced outcome. These 3 variables allowed us to develop a simple score system which identifies 4 subgroups of patients with 84%, 64%, 43% and 0% overall survival at five years after cGVHD diagnosis (score 0: HR=15.96 (95% CI: 6.85-37.17), P<0.001; score 1: HR=5.47 (95% CI: 2.6-11.5), P<0.001; score 2: HR=2.8 (95% CI: 1.32-5.93), P=0.007).CONCLUSIONS:In summary, we have identified a powerful and simple tool to discriminate different subgroups of patients in terms of chronic graft-versus-host disease related mortality and survival.

  • High-dose therapy and autologous stem-cell transplantation in angioimmunoblastic lymphoma : complete remission at transplantation is the major determinant of Outcome-Lymphoma Working Party of the European Group for Blood and Marrow Transplantation
  • 2008
  • Ingår i: Journal of Clinical Oncology. - 0732-183X .- 1527-7755. ; 26:2, s. 218-224

    • PURPOSE: Patients with angioimmunoblastic T-cell lymphoma (AITL) have poor prognoses with current conventional chemotherapy. The aim of this study was to evaluate the effect of high-dose therapy (HDT) followed by autologous stem-cell transplantation (ASCT) on patients with AITL. PATIENTS AND METHODS: We report a retrospective, multicenter study of 146 patients with AITL who received ASCT. The source of the stem cells was peripheral blood in 143 patients. The conditioning regimen varied, and 74% of the patients received carmustine and 1,3-bis(2-chloroethyl)-1-nitrosourea; etoposide; ara-C; and melphalan chemotherapy. RESULTS: After a median follow-up of 31 months (range, 3 to 174 months), 95 patients (65%) remained alive, and 51 patients (35%) died. Forty-two patients died as a result of disease progression, and nine died as a result of regimen-related toxicity. The cumulative incidence of nonrelapse mortality was 5% and 7% at 12 and 24 months, respectively. The actuarial overall survival (OS) was 67% at 24 months and 59% at 48 months. The cumulative incidence of relapse was estimated at 40% and 51% at 24 and 48 months, respectively. Disease status at transplantation was the major factor that impacted outcome. Patients who received a transplant during first complete remission (CR) had significantly superior progression-free survival and OS. The estimated PFS rates for patients who received their transplants in CR were 70% and 56% at 24 and 48 months, respectively; 42% and 30% for patients with chemotherapy-sensitive disease at those time points, respectively; and 23% at both time points for patients with chemotherapy-refractory disease. CONCLUSION: This study shows that HDT and ASCT offers the possibility of long-term disease-free survival to patients with AITL. Early transplantation is necessary to achieve optimal results.
