Effect of Conditioning Regimen Intensity on Acute Myeloid Leukemia Outcomes after Umbilical Cord Blood Transplantation

Reduced-intensity conditioning (RIC) umbilical cord blood (UCB) transplantation is increasingly used in hematopoietic stem cell transplantation (HCT) for older and medically unfit patients. Data on the efficacy of HCT after RIC relative to myeloablative conditioning (MAC) are limited. We compared the outcomes of acute myeloid leukemia (AML) patients >18 yrs who received UCB grafts after either RIC or MAC. One hundred nineteen adult patients with AML in complete remission (CR) underwent an UCB transplant after RIC (n =74, 62%) or MAC (n = 45, 38%) between January 2001 and December 2009. Conditioning was either reduced intensity and consisted of cyclophosphamide 50 mg/kg, fludarabine 200 mg/m2, and total-body irradiation (TBI) 200 cGy or myelablative and consisted for cyclophosphamide 120 mg/kg, fludarabine 75 mg/m2, and TBI 1200-1320 cGy. All patients received cyclosporine (day −3 to day +180) and mycophenolate mofetil (day −3 to day +45) post-HCT immunosuppression and hematopoietic growth factor. Use of RIC was reserved for patients >45 years (n = 66, 89%) or preexisting severe comorbidities (n = 8, 11%). The 2 groups were similar except for preceding myelodysplastic syndrome (RIC = 28% versus MAC = 4%, P < .01) and age that was dictated by the treatment protocols (median, RIC = 55 years versus MAC = 33years; P < .01). The incidence of neutrophil recovery at day +42 was higher with RIC (94% versus MAC = 82%, P < .1), whereas platelet recovery at the sixth month was similar (RIC = 68% versus MAC = 67%, P = .30). Incidence of grade II-IV acute graft-versus-host disease (aGVHD) (RIC = 47% versus MAC = 67%, P < .01) was decreased with similar incidence of chronic GVHD (cGVHD) (RIC = 30% versus MAC = 34%, P = .43). Median follow-up for survivors was 3.8 and 4.5 years for RIC and MAC, respectively (P = .4). Using RIC, 3-year leukemia-free survival (LFS) was decreased (31% versus MAC = 55%, P = .02) and 3-year relapse incidence was increased (43% versus MAC = 9%, P < .01). Two-year transplant-related mortality (TRM) was similar (RIC = 19% versus MAC = 27%; P = .55). In multivariate analysis, RIC recipients and those in CR2 with CR1 duration <1 year had higher risk of relapse and poorer LFS with no independent predictors of TRM. UCB with RIC extends the use of allogeneic HCT for older and frail patients without excessive TRM with greater benefit for patients in CR1 and CR2 with longer CR1

O cinema no ensino da psicoterapia psicodinâmica

O ensino da psicoterapia de orientação psicanalítica (PP) na Residência e Curso de Especialização em Psiquiatria da Infância e Adolescência da UFRGS/ HCPA ocorre há várias décadas, embasado principalmente no marcado perfil psicanalítico e psicodinâmico da formação psiquiátrica em nosso estado. Na década de 1980, introduziu-se a psicoterapia familiar (TF) e nos anos de 1990, a terapia cognitivo-comportamental (TCC). Os autores apresentam e revisam o ensino dessas três abordagens psicoterápicas desenvolvidas com crianças, adolescentes e suas famílias neste serviço. São também utilizadas as terapias de grupo, associadas ou não a outras abordagens, adequandoas ao diagnóstico, à faixa etária dos pacientes e ao seu contexto familiar e cultural. O objetivo dessas intervenções é o de tratar crianças, adolescentes e suas famílias, auxiliando-os a superar os bloqueios ao desenvolvimento, promovendo suas capacidades e amadurecimento

Does the Hematopoietic Cell Transplantation Specific Comorbidity Index Predict Transplant Outcomes? A Validation Study in a Large Cohort of Umbilical Cord Blood and Matched Related Donor Transplants

AbstractThe hematopoietic cell transplantation specific comorbidity index (HCT-CI) has been recently proposed to predict the probability of nonrelapse mortality (NRM) and overall survival (OS) in allogeneic HCT recipients while taking into account any pretransplant comorbidity. We tested the validity of the HCT-CI in a cohort of 373 adult HCT recipients (184 matched-related donor and 189 unrelated umbilical cord blood) who received a myeloablative (N = 150) or nonmyeloablative (N = 223) conditioning regimen. HCT-CI scores of 0, 1, 2, and ≥3 were present in 58 (16%), 56 (15%), 64 (17%), and 195 (52%) patients, respectively. Pulmonary conditions were the most common comorbidity. Cumulative incidence of NRM at 2 years was 10%, 20%, 24%, and 28% for HCT-CI scores of 0, 1, 2, and ≥3, respectively (P = .01). The corresponding probability of OS at 2 years was 72%, 67%, 51%, and 48%, respectively (P < .01). On multivariate analyses adjusted for recipient age, disease risk, donor source, and conditioning regimen intensity, the relative risks for NRM for HCT-CI scores of 1, 2, and ≥3 (compared to a score of 0) were 2.0 (95% confidence intervals, 0.8–5.3), 2.6 (1.0–6.7), and 3.2 (1.4-7.4), respectively. The risks for overall mortality were 1.2 (0.6-2.1), 2.0 (1.1-3.4), and 2.1 (1.3-3.3), respectively. In subgroup analyses, the HCT-CI score did not consistently predict NRM and OS among different donor sources and conditioning regimens. The HCT-CI, although a useful tool for capturing pretransplant comorbidity and risk-assessment, needs to be further validated prior to adopting it for routine clinical use

The effect of inter-unit HLA matching in double umbilical cord blood transplantation for acute leukemia

The effects of inter-unit HLA-match on early outcomes with regards to double cord blood transplantation have not been established. Therefore, we studied the effect of inter-unit HLA-mismatching on the outcomes of 449 patients with acute leukemia after double cord blood transplantation. Patients were divided into two groups: one group that included transplantations with inter-unit mismatch at 2 or less HLA-loci (n=381) and the other group with inter-unit mismatch at 3 or 4 HLA-loci (n=68). HLA-match considered low resolution matching at HLA-A and -B loci and allele-level at HLA-DRB1, the accepted standard for selecting units for double cord blood transplants. Patients’, disease, and transplant characteristics were similar in the two groups. We observed no effect of the degree of inter-unit HLA-mismatch on neutrophil (Hazard Ratio 1.27, P=0.11) or platelet (Hazard Ratio 0.1.13, P=0.42) recovery, acute graft-versus-host disease (Hazard Ratio 1.17, P=0.36), treatment-related mortality (Hazard Ratio 0.92, P=0.75), relapse (Hazard Ratio 1.18, P=0.49), treatment failure (Hazard Ratio 0.99, P=0.98), or overall survival (Hazard Ratio 0.98, P=0.91). There were no differences in the proportion of transplants with engraftment of both units by three months (5% after transplantation of units with inter-unit mismatch at ≤2 HLA-loci and 4% after transplantation of units with inter-unit mismatch at 3 or 4 HLA-loci). Our observations support the elimination of inter-unit HLA-mismatch criterion when selecting cord blood units in favor of optimizing selection based on individual unit characteristics

Health-Related Quality of Life Following Allogeneic Hematopoietic Cell Transplantation with Omidubicel versus Umbilical Cord Blood

Omidubicel is an advanced cell therapy derived from umbilical cord blood (UCB) for use in allogeneic hematopoietic cell transplantation (HCT). A recent randomized phase 3 clinical trial demonstrated faster engraftment, shorter length of hospital stays, and lower rates of infection with omidubicel compared with standard UCB transplantation in patients with high-risk hematologic malignancies. Despite the proven clinical benefits of omidubicel, its impact on health-related quality of life (HRQL) from the patient's perspective has not been described. This study analyzed patient-reported HRQL measures collected prospectively in the randomized phase 3 trial comparing omidubicel to standard UCB transplantation. A total of 108 patients at 33 international stem cell transplantation centers underwent myeloablative allogeneic HCT with either omidubicel or standard UCB. Patients completed serial HRQL questionnaires at screening and on days 42, 100, 180, and 365 post-transplantation. The HRQL surveys included the Functional Assessment of Cancer Therapy-Bone Marrow Transplant (FACT-BMT), a 50-item cancer-specific questionnaire assessing physical, functional, emotional, social/family, and HCT-specific well-being, and the EuroQol 5-Dimension 3-Level, a 5-item generic HRQL survey. A mixed model with repeated measures was used to compare changes in HRQL from baseline in the 2 treatment arms. The average change in HRQL scores over time was compared by estimating the difference in the area under the curve (AUC) in each treatment group. Seventy-five patients (omidubicel arm, n = 37; standard UCB arm, n = 38) who completed the FACT-BMT at baseline and on 1 or more follow-up visits were included in this study. Baseline characteristics were similar in the 2 treatment arms. Over the first year post-transplantation, the AUCs of mean changes in physical, functional, and total FACT-BMT scores indicated significantly better HRQL with omidubicel (P < .05), with mean differences across time points ranging from 1.4 to 3.1 points, 1.6 to 3.2 points, and 7.2 to 11.0 points, respectively. The minimal clinically important difference was exceeded at 1 or more time points for each of these measures. The HRQL improvements with omidubicel were observed as early as 42 days post-transplantation and persisted at 1 year, indicating the potential long-term benefits of omidubicel on HRQL. Across all patients, adverse clinical outcomes, such as grade 3 viral infections and lower rates of neutrophil engraftment, were associated with worse HRQL scores. The observed improvements in HRQL measures may reflect the known clinical benefits of omidubicel. Compared with standard UCB, allogeneic HCT with omidubicel resulted in significant and clinically meaningful improvements in patient-reported HRQL measures
