This was an Australasian Bone Marrow Transplant Recipient Registry (ABMTRR)-based retrospective study assessing the outcome of Fludarabine Melphalan (FluMel) reduced-intensity conditioning between 1998 and 2008. Median follow-up was 3.4 years. There were 344 patients with a median age of 54 years . In all, 234 patients had myeloid malignancies, with AML (n ¼ 166) being the commonest indication. There were 110 lymphoid patients with non-hodgkins lymphoma (NHL) (n ¼ 64) the main indication. TRM at day 100 was 14% with no significant difference between the groups. OS and disease-free survival (DFS) were similar between myeloid and lymphoid patients (57 and 50% at 3 years, respectively). There was no difference in cumulative incidence of relapse or GVHD between groups. Multivariate analysis revealed four significant adverse risk factors for DFS: donor other than HLAidentical sibling donor, not in remission at transplant, previous autologous transplant and recipient CMV positive. Chronic GVHD was associated with improved DFS in multivariate analysis predominantly due to a marked reduction in relapse (HR:0.44, P ¼ 0.003). This study confirms that FluMel provides durable and equivalent remissions in both myeloid and lymphoid malignancies. Disease stage and chronic GVHD remain important determinants of outcome for FluMel allografting.
Background: Double-hit lymphoma (DHL) is an aggressive subtype of high-grade B-cell lymphoma with inferior prognosis using standard dose chemotherapy. Controversy remains whether more intensive chemotherapy regimens such as dose-adjusted etoposide, prednisolone, vincristine, cyclophosphamide, doxorubicin and rituximab (DA-EPOCH-R) provide better outcomes in this cohort.Aims: To review consecutive cases of DHL treated with DA-EPOCH-R at our institution in comparison to available literature.
Methods:We conducted a retrospective study of 13 consecutive patients with DHL treated with DA-EPOCH-R at our institution. Primary endpoints included complete response (CR), event-free survival (EFS) and overall survival (OS).Results: CR rate with DA-EPOCH-R in DHL was 69% in our cohort. Median EFS and OS duration was 61 months (95% CI: 41-86 months) and 64 months (95% CI: 42-86 months) respectively. One patient discontinued DA-EPOCH-R due to recurrent febrile neutropenia and there were no treatment or infection-related deaths during the study.Conclusions: This study suggests that DA-EPOCH-R is a well tolerated outpatient regimen for DHL and should be considered for initial treatment in medically fit patients. Further prospective studies are warranted to confirm these findings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
