Chimeric Antigen Receptor T-cell Therapy (CAR-T) is a novel cellular immunotherapy technology that has shown excellent efficacy in the treatment of refractory relapsed diffuse large B-cell lymphoma (DLBCL). Despite this, a significant number of patients do not respond to the treatment or experience relapse and progression. How to further improve the efficacy of CAR-T cells is a key focus of future research. At the recently held "2024 Nanjing Lymphoma Forum," Professor Wenbin Qian from The Second Affiliated Hospital of Zhejiang University School of Medicine delivered a brilliant report titled "Mechanisms of CAR-T Resistance Based on DLBCL Pathological Characteristics and Countermeasures." After the conference, "Oncology Frontier - Hematologie Frontier" invited Professor Wenbin Qian for an interview to further discuss this topic.

Graft failure is a rare but fatal complication following haploidentical allogeneic hematopoietic stem cell transplantation. A second transplant is almost the only salvage measure for transplant failure. However, outcomes from second transplants have generally been poor, as reported in previous literature. The 50th European Society for Blood and Marrow Transplantation (EBMT) annual meeting was held in Glasgow, UK, from April 14th to 17th, 2024. The conference focused on the latest advancements in stem cell transplantation and cellular therapy, driving better clinical outcomes for patients with blood disorders. At this conference, a team led by Professor Yuqian Sun from Peking University People's Hospital presented their findings in an oral report titled "Salvage Haploidentical Transplantation with Flu/Cy Regimen and Donor Switching After Primary Graft Failure: Follow-Up Results," which garnered significant attention. Professor Sun was invited to share the main results of this study and the progress in salvage treatments for graft failure after haploidentical allogeneic hematopoietic stem cell transplantation.

As scheduled, the 2024 China Society of Clinical Oncology (CSCO) guidelines conference has arrived, with many CSCO oncology treatment guidelines being updated or published for the first time. In the field of hematologic oncology, the much-anticipated CAR-T cell therapy guidelines have been significantly updated. The "CSCO CAR-T Cell Therapy for Malignant Hematological Diseases and Management of Related Infections Guidelines 2023" (referred to as the 2023 Guidelines) has been renamed to "CSCO CAR-T Cell Therapy for Malignant Hematological Diseases Guidelines 2024" (referred to as the 2024 Guidelines). At the conference, Professor Wenjun Zhang from Tongji Hospital affiliated with Tongji University and the Tongji University Institute of Hematology shared the key updates of the 2024 Guidelines. The highlights are organized below for our readers.
