Even with novel therapies, only approximately 20%-25% of patients attain complete remissions, with a median progression-free survival (PFS) of approximately 5-15 months. Lenalidomide has been shown to have activity in relapsed HL. We retrospectively analyzed the outcomes of patients with relapsed HL post AuSCT treated with le-nalidomide alone or in combination with dexamethasone at our center. Patients and methods : Records of 143 patients transplanted from November 2007 to October 2021 were reviewed. Of these patients, 41 (28%) relapsed, and 16 (39%) received lenalidomide alone or in combination with dexamethasone. Data collected included demographic, pathological, staging, and prior therapy details. Le-nalidomide was administered at 10-25 mg/day on an intermittent or continuous schedule alone or in combination with dexamethasone (20-40 mg weekly). Response was assessed using PET-CT scan in accordance with Lugano criteria. Standard definitions were used for response, PFS, and overall survival (OS). Toxicities were graded using Common Terminology Criteria for Adverse Events version 5.0. Statistical analysis was done using SPSS Version 21. Results : The median age of the patients was 25.5 years, and 10 were males. Eleven (69%) had advanced disease, and 7 (44%) were refractory to last systemic therapy. Nine patients received lenalidomide alone and 7 with dexamethasone. Four (25%) had complete response, and another four (25%) had partial response, with an overall response rate of 50%. The 3-year PFS and OS were 31% and 38%, respectively. Grade III/IV toxicities were only hematological, neutropenia and thrombocytopenia in four and three patients, respectively. No therapy-related deaths were recorded. Conclusions : Lenalidomide alone or in combination with dexamethasone is a safe and effective therapy for re-lapsed HL post AuSCT and results in durable response and long-term survival in approximately one-third of the patients. However, these results needs verification in larger prospective studies.","PeriodicalId":72423,"journal":{"name":"Blood cell therapy","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135401233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

International data in the haplo-HCT setting is mainly using bone marrow as a source. Almost all HCTs in India use peripheral blood stem cells (PBSC), which increases the risk of graft-versus-host disease (GVHD). In this single-center prospective study from 2017 to 2021, we sought to compare these outcomes prospectively in adult patients with hematological malignancies. Patient, disease, donor, and HCT details were prospectively recorded. GVHD prophylaxis included cyclosporine + methotrexate in MRD-HCT and post-transplant cyclophosphamide (PTCy) based in haplo-HCT. The primary endpoint GVHD relapse-free survival (GRFS) was defined as the time post-HCT without any of the following events: grade III-IV acute GVHD, chronic GVHD requiring systemic immunosuppressive treatment, disease relapse, or death from any cause. A total of 41 MRD and 33 haplo-HCT recipients were included in the study. Both cohorts were matched for age, sex, diagnosis, disease risk index, donor age, sex and CMV mismatches, and CD34 counts. A lower proportion of MRD-HCT recipients than haplo-HCT received myeloablative conditioning (39% vs. 76%, p = 0.002). There was no difference in the cumulative incidence of grade III-IV acute GVHD (16% vs. 27%, p = 0.2) or moderate-to-severe chronic GVHD (58% vs. 71%, p = 0.5). The one-year GRFS was not significantly different (53% vs. 38%, p = 0.2), with median GRFS of 420 and 274 days. The relapse incidence (22% vs. 19%, p = 0.6) and non-relapse mortality (25% vs. 35%, p = 0.4) did not differ. There was no difference in overall survival at one year (60% vs. 52%, p = 0.3). Despite a higher proportion of myeloablative conditioning in the haplo-HCT cohort, all outcomes, including GRFS, were comparable to those of the MRD-HCT cohort. This should encourage patients without an MRD to undergo haplo-HCT.","PeriodicalId":72423,"journal":{"name":"Blood cell therapy","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135401528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we describe three cases of FLT3 mutated RR-AML that were successfully treated with gilteritinib administration before and after allo-HCT.

However, HCT often resulted in mild liver damage, and careful introduction of gilteritinib after HCT at a lower dose may be helpful for its safe usage.

Previous studies have reported copy number variants of genes such as IKZF1 , CDKN2A/2B , and PAX5 . These gene mutations can be analyzed using multiplex ligation-dependent probe amplification (MLPA), which is less costly and easier to perform than large-scale gene mutation analyses. In this study, we performed copy number variant analysis of leukemia cells at the first onset of Ph+ALL in a case series of allogeneic hematopoietic stem cell transplantation (allo-HSCT) using the MLPA method. We analyzed how it influenced allo-HSCT prognosis together with MRD information. CDKN2A/2B copy number variations significantly increased the rate of post-transplant recurrence (P=0.025) and significantly reduced disease-free survival (P=0.015). Additionally, patients with IKZF1 deletions had a significantly higher post-transplant recurrence rate (P=0.042). Although they were positive for pre-transplant MRD, no relapse was observed in patients with wild-type copy number variations in IKZF1 or CDKN2A/2B .

In this study, we used Everolimus as maintenance therapy after ASCT among patients with relapsing/refractory Hodg-kin lymphoma. Materials and Methods : We collected the data of 20 patients with primary refractory or relapsing Hodgkin lymphoma who had undergone ASCT between June 2016 and June 2021. Everolimus was started at 10 mg daily on day +90 after ASCT for at least two years in patients with stable disease status, confirmed by imaging modalities. Patients were followed for disease status and drug side effects every 3 months. Results : In our single-arm case-series study, the median duration of treatment was 22.95 months. Except for three patients, who had progression, others had no progression and are still receiving Everolimus (85%). No serious side effect was seen. We had no mortality due to disease recurrence.
