Management of aggressive, usually late-occurring, post-transplant lymphoproliferative disorders (PTLDs), a life-threatening complication after solid organ transplants, remains controversial. Four children affected by aggressive CD20+ PTLDs received a chemo-immunotherapy regimen for remission induction based on fludarabine, cyclophosphamide, doxorubicin, and rituximab, associated with a rapid discontinuation of immunosuppression (IS). Subsequent consolidation chemotherapy consisted of Berlin-Frankfurt-Münster-modified blocks. All patients achieved a complete remission, which persisted for 25, 68+, 80+, and 103+ months after diagnosis. Therapy was well tolerated. No patients developed allograft rejection during PTLD treatment. Our experience suggests that this chemo-immunotherapeutic approach may be an effective treatment strategy while allowing for a concomitant discontinuation of IS.

A 66-year-old woman was diagnosed with chronic lymphocytic leukemia (CLL) due to the finding of leukocytosis and started acalabrutinib and obinutuzumab (AO) therapy. After three cycles of AO therapy, she developed severe pancytopenia with hypoplastic bone marrow and was diagnosed with fulminant aplastic anemia (AA) due to neutropenia with no response to granulocyte colony-stimulating factor. One month after the onset of AA, she received HLA-haploidentical allogeneic hematopoietic stem cell transplantation (haplo-SCT) from a daughter using FluMelTBI (fludarabine 180 mg/m, melphalan 80 mg/m, total body irradiation 4 Gy) as the conditioning regimen and tacrolimus, mycophenolate mofetil, and post-transplant cyclophosphamide (PTCy) for graft-versus-host disease (GVHD) prophylaxis.

This study aimed to summarize the clinical characteristics and prognosis of patients with bone marrow invasive follicular lymphoma (FL) and discuss the treatment modalities. This study included 183 consecutive patients with FL accompanied by bone marrow invasion and receiving regular treatment at the Hospital of Hematology, Chinese Academy of Medical Sciences, from January 2013 to December 2022. Clinical data were retrospectively collected and analyzed, and single and multifactorial analyses of survival prognosis were conducted with the Kaplan-Meier method and Cox regression model.

Individuals with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) have a high risk of developing other malignancies (OMs). The development of OMs may be associated with the advanced age of CLL/SLL patients, presence of a tumor-promoting microenvironment, immune alterations inherent to CLL/SLL, or chemotherapy. Importantly, the occurrence of OMs following frontline fludarabine, cyclophosphamide and rituximab (FCR) treatment is associated with a reduction in the overall survival (OS).

Background: Post-transplant cyclophosphamide (PTCy) is a commonly used graft-vs-host disease (GVHD) prophylaxis, particularly in the setting of haploidentical (haplo) hematopoietic cell transplantation (HCT). The rate of graft failure has been reported to be as high as 12-20% in haplo-HCT recipients using PTCy. The objective of this study was to determine if donor type influenced the risk of late graft failure following RIC HCT using PTCy-based GVHD prophylaxis.

Background: The management of high-risk acute myeloid leukaemia (AML) remains challenging, highlighting the need for innovative conditioning strategies beyond current regimens.
Methods: In the present single-arm study, a FACT regimen comprised of low-dose total body irradiation (TBI) with fludarabine, cytarabine and cyclophosphamide was employed to treat cytogenetically high-risk AML patients exhibiting pre-transplant active disease. This clinical trial is registered in the Chinese Clinical Trial Registry with the registration number ChiCTR2000035111.
