    • 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

    • 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.

  • Long-term survival of patients with CLL after allogeneic transplantation : A report from the European Society for Blood and Marrow Transplantation
  • 2017

    • Even with the availability of targeted drugs, allogeneic hematopoietic cell transplantation (allo-HCT) is the only therapy with curative potential for patients with CLL. Cure can be assessed by comparing long-term survival of patients to the matched general population. Using data from 2589 patients who received allo-HCT between 2000 and 2010, we used landmark analyses and methods from relative survival analysis to calculate excess mortality compared with an age-, sex- and calendar year-matched general population. Estimated event-free survival, overall survival and non-relapse mortality (NRM) 10 years after allo-HCT were 28% (95% confidence interval (CI), 25-31), 35% (95% CI, 32-38) and 40% (95% CI, 37-42), respectively. Patients who passed the 5-year landmark event-free survival (N=394) had a 79% probability (95% CI, 73-85) of surviving the subsequent 5 years without an event. Relapse and NRM contributed equally to treatment failure. Five-year mortality for 45- and 65-year-old reference patients who were event-free at the 5-year landmark was 8% and 47% compared with 3% and 14% in the matched general population, respectively. The prospect of long-term disease-free survival remains an argument to consider allo-HCT for young patients with high-risk CLL, and programs to understand and prevent late causes of failure for long-term survivors are warranted, especially for older patients.

  • Health-related quality of life data from a phase 3, international, randomized, open-label, multicenter study in patients with previously treated mantle cell lymphoma treated with ibrutinib versus temsirolimus

    • Mantle cell lymphoma (MCL) is a rare, aggressive, incurable B-cell malignancy. Ibrutinib has been shown to be highly active for patients with relapsed/refractory (R/R) MCL. The RAY trial (MCL3001) was a phase 3, randomized, open-label, multicenter study that compared ibrutinib with temsirolimus in patients with R/R MCL. Active disease is frequently associated with impaired functional status and reduced well-being. Therefore, the current study employed two patient-reported outcome instruments, the Functional Assessment of Cancer Therapy-Lymphoma (FACT-Lym) and the EQ-5D-5L, to assess symptoms, well-being, health status, and health-related quality of life of patients on treatment within the RAY trial. We found that patients on ibrutinib had substantial improvement in FACT-Lym subscale and total scores, and had improvement in EQ-5D-5L utility and VAS scores compared with temsirolimus patients, indicating a superior well-being. These improvements in well-being correlated with clinical response, indicating that better health-related quality of life was associated with decreased disease burden.

  • 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.
