Abstract
Autologous hematopoietic cell transplantation (auto-HCT) has long remained the standard approach for patients with relapsed/refractory (R/R) chemosensitive diffuse large B-cell lymphoma (DLBCL). However, the advent of chimeric antigen receptor (CAR) T-cell therapy has caused a paradigm shift in the management of R/R DLBCL patients, especially with the recent approval of CD19-directed CAR T-cell therapy in the second line setting in high-risk groups (primary refractory and early relapse [≤12 months]). Consensus on the contemporary role, optimal timing, and sequencing of HCT and cellular therapies in DLBCL is lacking. Therefore, the American Society of Transplantation and Cellular Therapy (ASTCT) Committee on Practice Guidelines undertook this project to formulate consensus recommendations to address this unmet need. The RAND-modified Delphi method was used to generate 20 consensus statements with a few key statements as follows: 1) in the first-line setting, there is no role of auto-HCT consolidation for those achieving complete remission (CR) following R-CHOP or similar therapy in non-double hit/triple hit cases (DHL/THL) and in DHL/THL cases receiving intensive induction therapies, but auto-HCT may be considered in eligible patients receiving R-CHOP or similar therapies in DHL/THL cases. 2) Auto-HCT consolidation with thiotepa-based conditioning is standard-of-care for eligible patients with primary central nervous system achieving CR with first-line therapy. 3) In the primary refractory and early relapse setting, the preferred option is CAR T-cell therapy, while in late relapse (>12 months), consolidation with auto-HCT is recommended in those achieving chemosensitivity to salvage therapy (CR or partial response), and CAR T-cell therapy is recommended in those not achieving remission. These clinical practice recommendations will serve as a tool to guide clinicians managing patients with newly diagnosed and R/R DLBCL.

Abstract
Germline predisposition to haematological cancers is increasingly being recognised. Widespread adoption of high-throughput and whole genome sequencing is identifying large numbers of causative germline mutations. Constitutional pathogenic variants in six genes (DEAD-box helicase 41 [DDX41], ETS variant transcription factor 6 [ETV6], CCAAT enhancer binding protein alpha [CEBPA], RUNX family transcription factor 1 [RUNX1], ankyrin repeat domain containing 26 [ANKRD26] and GATA binding protein 2 [GATA2]) are particularly significant in increasing the risk of haematological cancers, with variants in some of these genes also associated with non-malignant syndromic features. Allogeneic blood and marrow transplantation (BMT) is central to management in many haematological cancers. Identification of germline variants may have implications for the patient and potential family donors. Beyond selection of an appropriate haematopoietic stem cell donor there may be sensitive issues surrounding identification and counselling of hitherto asymptomatic relatives. If BMT is needed, there is frequently a clinical urgency that demands a rapid integrated multidisciplinary approach to testing and decision making involving haematologists in collaboration with Clinical and Laboratory Geneticists. Here, we present best practice consensus guidelines arrived at following a meeting convened by the UK Cancer Genetics Group (UKCGG), the Cancer Research UK (CRUK) funded CanGene-CanVar research programme (CGCV), NHS England Genomic Laboratory Hub (GLH) Haematological Oncology Malignancies Working Group and the British Society of Blood and Marrow Transplantation and Cellular Therapy (BSBMTCT).

Abstract
Evaluation of a candidate for hematopoietic cell transplant (HCT) is a complex process with substantial inter-center variability. Although literature providing guidance for evaluating the eligibility of adults is well established, similar guidance for children is lacking. To address gaps between adult recommendations and the specific needs of children, we convened a panel of pediatric HCT experts from a wide geographic range of American Society of Transplantation and Cellular Therapy (ASTCT) member institutions to offer pediatric-focused pre-HCT evaluation recommendations. In this report from the ASTCT Committee on Practice Guidelines, we present a practical framework for evaluating children with malignancies who are candidates for HCT. We also highlight key differences from adults and emphasize areas of unmet need that require additional research to delineate best practices.

Abstract
Treatment of chronic myeloid leukemia has improved significantly with the introduction of tyrosine kinase inhibitors (TKIs), and treatment guidelines based on numerous clinical trials are available for chronic phase disease. However for CML in the blast phase (CML-BP), prognosis remains poor and treatment options are much more limited. The spectrum of treatment strategies for children and adolescents with CML-BP has largely evolved empirically and includes treatment principles derived from adult CML-BP and pediatric acute leukemia. Given this heterogeneity of treatment approaches, we formed an international panel of pediatric CML experts to develop recommendations for consistent therapy in children and adolescents with this high-risk disease based on the current literature and national standards. Recommendations include detailed information on initial diagnosis and treatment monitoring, differentiation from Philadelphia-positive acute leukemia, subtype-specific selection of induction therapy, and combination with tyrosine kinase inhibitors. Given that allogeneic hematopoietic stem cell transplantation currently remains the primary curative intervention for CML-BP, we also provide recommendations for the timing of transplantation, donor and graft selection, selection of a conditioning regimen and prophylaxis for graft-versus-host disease, post-transplant TKI therapy, and management of molecular relapse. Management according to the treatment recommendations presented here is intended to provide the basis for the design of future prospective clinical trials to improve outcomes for this challenging disease.

Abstract
The advent of new technologies has made it possible to identify genetic predispositions to myelodysplastic syndromes (MDS) and acute leukemias (AL) more frequently. The most frequent and best characterized at present are mutations in CEBPA, RUNX1, GATA2, ETV6 and DDX41 and, either in the presence of one of these mutations with a high allelic frequency, or in the case of a personal or family history suggestive of blood abnormalities such as non-immune thrombocytopenia, it is recommended to look for the possibility of a hereditary hematological malignancy (HHM). Indeed, early recognition of these HHMs allows better adaptation of the management of patients and their relatives, as allogeneic hematopoietic stem cell transplantation (HSCT) is very often proposed for these pathologies. According to current data, with the exception of the GATA2 mutation, the constitutional or somatic nature of the mutations does not seem to influence the prognosis of hematological diseases. Therefore, the indication for an allograft will be determined according to the usual criteria. However, when searching for a family donor, it is important to ensure that there is no hereditary disease in the donor. In order to guarantee the possibility of performing the HSC allograft within a short period of time, it may be necessary to initiate a parallel procedure to find an unrelated donor. Given the limited information on the modalities of HSC transplantation in this setting, it is important to assess the benefit/risk of the disease and the procedure to decide on the type of conditioning (myeloablative or reduced intensity). In view of the limited experience with the risk of secondary cancers in the medium and long-term, it may be appropriate to recommend reduced intensity conditioning, as in the case of better characterized syndromic hematological diseases such as Fanconi anemia or telomere diseases. In summary, it seems important to evoke HHM more frequently, particularly in the presence of a family history, certain mutations or persistent blood abnormalities, in order to discuss the specific modalities of HSC allografting, particularly with regard to the search for a donor and the evaluation of certain modalities of the procedure, such as conditioning. It should be noted that the discovery of HHM, especially if the indication of an allogeneic HSC transplant is retained, will raise ethical and psychological considerations not only for the patient, but also for his family. A multidisciplinary approach involving molecular biologists, geneticists, hematologists and psychologists is essential.

Abstract
The role of allogeneic hematopoietic stem cell transplantation (HCT) in the treatment of acute myelogenous leukemia (AML) in children is reviewed and critically evaluated in this evidence-based review. Specific criteria were used for searching the published literature, grading the quality and strength of evidence, and assigning the strength of treatment recommendations. Genomic characterization and response to therapy have been critical in the risk stratification of pediatric AML. Although some children are cured with chemotherapy alone, allogeneic HCT offers a survival benefit in selected patients with certain unfavorable risk features and is the standard of care for children who relapse following initial treatment with chemotherapy. Important aspects of HCT include recipient characteristics, donor source, and preparative regimen. The goals of HCT are to reduce incidence of relapse, enhance graft-versus-leukemia (GVL) effects, and minimize graft-versus-host disease. Relapse following HCT remains a significant cause of treatment failure, and interventions pre- and post-HCT, especially those that may augment GVL, are an important focus of ongoing investigations.

[Guidelines for the diagnosis and management of multiple myeloma in China (2022 revision)]
Zhonghua nei ke za zhi. 2022;61(5):480-487
Abstract
Multiple myeloma (MM) is an incurable clonal plasma cell dysplasia, the second most hematological malignancy which mainly develops in elderly population. With the emerging novel agents and laboratory methods, the diagnosis and treatment of MM have been significantly improved. In this update version, the rare subtypes of MM were supplemented to the diagnosis part, and blood or urine M protein was not mandatory as diagnostic criteria for active myeloma. In the risk stratification part, more accurate standards were added. As novel agents including carfilzomib, pomalidomide and selinexor have been approved by CFDA, more alternative combination regimens were available for relapse and refractory patients. Overwhelmingly, autologous stem cell transplantation (ASCT) still plays an irreplaceable role in MM treatment. In the supportive treatment section, the administration of thromboprophylaxis and denosumab were added.

Abstract
BACKGROUND Chimeric antigen receptor T cell therapy (CAR-T) is a major advance in managing aggressive relapsed and/or refractory B-cell lymphomas; however, relapses are frequent and pose a major therapeutic challenge. There is substantial variability across transplant and cellular therapy programs in assessing and managing post-CAR-T failures. METHODS The American Society for Transplantation and Cellular Therapy (ASTCT) Committee on Practice Guidelines conducted an online cross-sectional survey between August 2021 and October 2021, to determine the U.S. lymphoma and transplant and cellular therapy physicians' practice patterns for the detection and diagnosis of CAR-T failure, and management strategies for diffuse large B cell lymphoma (DLBCL) in this particular setting. RESULTS Email surveys were sent to 901 potential participants, of which 174 (19%) completed the survey. Responders were mainly White (51.2%), male (70.7%), and with >10 years of practice experience (51.2%). 87% of the responders were affiliated with university/teaching centers; 54.6% had general oncology practices and 45.4% had lymphoma-focused transplant/cellular therapy practices. The most common periods to perform surveillance scans were at 3 months and 12 months after CAR-T infusion. 88.5% of responders would often or always consider a biopsy to confirm relapse and 89% would routinely check for the persistence of the antigen targeted by the CAR (e.g. CD19 in the case of CD19 CAR-T). The most popular first salvage regimen for relapse or progression was an alternate CAR-T therapy (dual or alternate target) regardless of CD19 positivity. 27% of responders chose this regimen for CD19 positive relapse, while 31% of responders did so for CD19 negative relapse. 88.5% of responders favored consolidative allogeneic hematopoietic cell transplantation (alloHCT) after response to salvage, whereas 51.2% of physicians would consider autologous hematopoietic cell transplant (AHCT) in transplant naïve patients. CONCLUSIONS There is substantial cross-center variation in surveillance, diagnosis, and management of CAR-T failure. Prospective clinical trials evaluating novel agents in this setting are urgently needed to identify best management strategies.

Abstract
Over the past decade, therapeutic options in multiple myeloma (MM) have changed dramatically. Given the unprecedented efficacy of novel agents, the role of hematopoietic cell transplantation (HCT) in MM remains under scrutiny. Rapid advances in myeloma immunotherapy including the recent approval of chimeric antigen receptor (CAR) T-cell therapy will impact the MM therapeutic landscape. The American Society for Transplantation and Cellular Therapy (ASTCT) convened an expert panel to formulate clinical practice recommendations for role, timing, and sequencing of autologous (auto-HCT), allogeneic (allo-HCT) and CAR T-cell therapy for patients with newly diagnosed (NDMM) and relapsed/refractory MM (RRMM). The RAND-modified Delphi method was used to generate consensus statements. Twenty consensus statements were generated. The panel endorsed continued use of auto-HCT consolidation for patients with NDMM as a standard-of-care option, whereas in the front line allo-HCT and CAR-T were not recommended outside the setting of clinical trial. For patients not undergoing auto-HCT upfront, the panel recommended its use in first relapse. Lenalidomide as a single agent was recommended for maintenance especially for standard risk patients. In the RRMM setting, the panel recommended the use of CAR-T in patients with 4 or more prior lines of therapy. The panel encouraged allo-HCT in RRMM setting only in the context of clinical trial. The panel found RAND-modified Delphi methodology effective in providing a formal framework for developing consensus recommendations for the timing and sequence of cellular therapies for MM.
