Abstract: This study was conducted to determine whether the integration of the Hematopoietic Cell Transplantation Comorbidity Index (HCT-CI) and the European Group for Blood and Marrow Transplantation (EBMT) score would improve individual capacity for stratification of high-risk HCT candidates. A total of 442 consecutive patients receiving an allogeneic HCT after reduced-toxicity conditioning was included. Final HCT-CI and EBMT scores were calculated and validated. Then, patients were grouped into a 6-category new combination model according to the HCT-CI (0, 1 to 2, ≥3) and EBMT scores (0 to 3, 4 to 7), and the model's predictive capacity was also evaluated. Median HCT-CI and EBMT scores were 3 and 4, respectively. Increased HCT-CI was associated with higher 4-year nonrelapse mortality (NRM) and lower 4-year overall survival (OS), whereas a high EBMT score was associated with higher 4-year NRM. The HCT-CI showed a trend for a better predictive capacity than the EBMT score (c-statistic .6 versus .54, P = .1). According to the new model, patients within HCT-CI of 0 and HCT-CI of 1 to 2 groups had similar risk of NRM independently of their EBMT score. Within the HCT-CI ≥ 3 group, patients with low EBMT score showed lower NRM (25% versus 40%, P = .04) and a trend to higher OS (52% versus 36%, P = .06) than patients with a high EBMT score. Moreover, patients with HCT-CI ≥ 3 and EBMT score 0 to 3 had similar outcomes than those with HCT-CI of 1 to 2. In conclusion, the combination of HCT-CI and the EBMT score is feasible and might contribute to a better identification of high-risk patients, improving selection of best allogeneic HCT candidates.

Abstract: Hyperferritinemia has been associated with adverse outcomes after allogeneic hematopoietic cell transplantation (allo-HCT) with myeloablative conditioning. However, its characteristics and impact on the outcome in the reduced-intensity conditioning (RIC) and in the lymphoid malignancy settings are far from clear. The study includes 201 adult patients undergoing allo-HCT with RIC (allo-RIC) for lymphoid malignancies with a median follow-up for survivors of 52 months (range, 3 to 123). Median serum ferritin level at allo-RIC was 379 ng/mL (range, 4 to 10,790). In the multivariate analysis, patients with hyperferritinemia at transplantation (>399 ng/mL) showed lower 4-year overall survival (hazard ratio [HR], 1.8 [95% confidence interval {CI}, 1.2 to 2.8]; P = .008), higher nonrelapse mortality (NRM) (HR, 1.8 [95% CI, 1.1 to 3.2]; P = .03), and higher infection-related mortality (HR, 2.3 [95% CI, 1.1 to 4.8]; P = .02) than patients without hyperferritinemia. Neutrophil and platelet engraftment and 100-day NRM were similar between both groups. The adverse outcome associated with hyperferritinemia seemed higher in patients without major comorbidities and was not influenced by the elevation of acute phase reactants. Our results indicate that high ferritin levels at HCT are associated with an adverse outcome after allo-RIC in patients with lymphoid malignancies. [Copyright &y& Elsevier]

Liver dysfunction is frequent before allogeneic stem cell transplantation (allo-SCT). However, its characteristics and impact on transplantation outcomes are uncertain, especially in the reduced-intensity conditioning (RIC) setting. We analyzed 455 patients receiving an allo-SCT in 3 Spanish centers. Pretransplantation aspartate aminotransferase (AST), alanine aminotransaminase (ALT), gamma-glutamyl transpeptidase (GGT), alkaline phosphatase (AP), total bilirubin, and international normalized ratio were analyzed. Pretransplantation liver function test abnormalities were found in 94 (22%) patients. The most frequent cause of pretransplantation liver dysfunction was isolated elevation of GGT/AP (n = 49, 53%). Patients with high bilirubin levels before allo-SCT showed higher 4-year nonrelapse mortality (4y-NRM) (hazard ratio [HR] 2 [95% confidence interval [CI] 1.1-3.8] P = .02) and patients with high GGT levels showed higher 100-day NRM and lower 4-year overall survival (OS) (HR 3.4 [95% CI 1.8-6.7] P < .001, and HR 2 [95% CI 1.4-3], P = .001), respectively. High levels of transaminases did not influence on survival or mortality. In conclusion, hepatic dysfunction before allo-SCT is frequent and has an impact on transplantation outcomes. The best indicator of liver dysfunction still has to be determined. [ABSTRACT FROM AUTHOR]
