Reduced Intensity

Allogeneic hematopoietic cell transplantation (allo-HCT) preconditioning intensity, donor choice, and graft-versus-host disease (GVHD) prophylaxis for advanced myelofibrosis (MF) have not been fully elucidated. Thirty-five patients with advanced MF were treated with reduced-intensity conditioning (RIC) allo-HCT. We searched for matched sibling (n=16) followed by matched (n=10) or mismatched (n=5) unrelated and familial mismatched donors (n=4). Preconditioning regimen consisted of fludarabine (total 150 mg/m2) and busulfan (total 6.4 mg/kg) with total body irradiation≤ 400cGy. All showed engraftments, but four (11.4%) showed either leukemic relapse (n=3) or delayed graft failure (n=1). Two-year overall survival (OS) and non-relapse mortality (NRM) was 60.0% and 29.9%, respectively. Acute GVHD was observed in 19 patients, and grade III-IV acute GVHD was higher with HLA-mismatch (70% vs. 20%, p=0.008). Significant hepatic GVHD was observed in nine patients (5 acute, 4 chronic), and six of them died. Multivariate analysis revealed inferior OS with HLA-mismatch (HR=6.40, 95%CI 1.6-25.7, p=0.009) and in patients with high ferritin level at post-HCT D+21 (HR=7.22, 95%CI 1.9-27.5, p=0.004), which were related to hepatic GVHD and high NRM. RIC allo-HCT can be a valid choice for advanced MF. However, HLA-mismatch and high post-HCT ferritin levels related to significant hepatic GVHD should be regarded as poor-risk parameters.

Abstract Allogeneic hematopoietic cell transplantation (HCT) using reduced intensity conditioning (RIC) regimens offers a potential curative therapy to patients with advanced NHL. RIC HCT induces potent graft-versus-lymphoma effects with best results in patients with low tumor burden at time of HCT. Combined use of radioimmunotherapy (RIT) with RIC may increase anti-lymphoma activity of RIC while HCT provides rescue from hematologic toxicity of RIT. This may allow dose escalation of RIT. A multicenter phase I/II study of allogeneic HCT combining RIT using yttrium-90-ibritumomab tiuxetan (Y90-CD20) with two RIC regimens for treatment of patients with NHL has been initiated. Patients with indolent NHL (Arm A) receive RIT with Y90-CD20 (0.4 mCi/kg) on day −14 combined with RIC using fludarabine (30 mg/m^2 day −4 to−2) and 2 Gy TBI (day 0). Patients with aggressive NHL (Arm B) receive an escalated dose of Y90-CD20 (0,6–0,8 mCi/kg) on day −14 combined with RIC using fludarabine (30 mg/m^2 day −8 to−4), melphalan (140 mg/m^2 day −3) and campath (20–30 mg day −3 to−2). For postgrafting immunosuppression either CSA/MMF (Arm A) or CSA alone (Arm B) is used. To date, 31 patients have been enrolled (Arm A=23, Arm B=8). Diagnoses in Arm A were FL (n=12), MCL (n=6), CLL (n=4) and Immunocytoma (n=1). Diagnoses in Arm B were DLBCL (n=6), blastoid MCL (n=1) and transformed CLL (n=1). Median age was 55 (range, 34–67) years. PBSC grafts were either from matched related (n=10) or matched unrelated donors (n=21). All patients were high risk with refractory disease or relapse after preceding HCT. Disease status after salvage therapy at time of HCT was in Arm A: CR=1, PR=18, SD=4 and in Arm B: PR=8. No additional toxicity due to RIT was observed. Engraftment was rapid and sustained with no graft rejections. In Arm A median time to >500 granulocytes/μL was 13 (range, 0–69) days and to >20000 platelets/μL 3 (range, 0–69) days (in 11 patients platelets never dropped <20000/μL). In Arm B median time to >500 granulocytes/μL was 17 (range, 9–23) days and to >20000 platelets/μL 11 (range, 8–29) days. TRM in the first 100 days was 3%, overall 19%. Incidence of grade II-IV GVHD in Arm A was 35% (II=3, III=4, IV=1) and in Arm B 25% (II=2). Best disease response observed was in Arm A: CR=18, PR=5 and in Arm B: CR=3, PR=5. To date, 16/23 patients in Arm A and 6/8 patients in Arm B are alive with a median follow-up of 271 (range, 20–390) days, resulting in a Kaplan-Meier 1 year survival estimate of 65% in Arm A and 62% in Arm B. Causes of death were infection=5, GVHD=1, relapse=1 in Arm A and relapse=2 in Arm B. A combination of RIT with RIC is feasible with no additional toxicity due to RIT and stable engraftment in all patients. Preliminary response data suggest that this strategy may improve early post-transplant disease control, but long-term disease-free survival remains to be determined.

AbstractProgress in the last decade has improved the understanding of leukemia biology. Molecular markers in combinations with cytogenetics have improved the risk stratification of acute myeloid leukemia (AML) and informed decision-making. In parallel, several important advances in the transplant field, such as better supportive care, improved transplant technology, increased availability of alternative donors, and reduced-intensity conditioning have improved the safety as well as access of allogeneic hematopoietic cell transplantation (HCT) for a larger number of patients. In this review, the positioning of HCT in the management of patients with AML is evaluated in view of changing risk/benefit ratios associated with both conventional treatments and transplantation, and some of the controversies are addressed in light of emerging data. Increasing data demonstrate outcomes of alternative donor transplantation approaching HLA-identical sibling donors in high-risk AML supporting the inclusion of alternative donors in trials of prospective studies evaluating post remission strategies for high-risk AML. The use of reduced-intensity conditioning has expanded the eligibility of HCT to older patients with AML, and outcome data are encouraging. Continued study of HCT versus alternative therapies is required to optimize patients' outcomes in AML.
