Abnormal plasma cells (CD38+, CD138+, Igλ≫κ) were detected in 1.4% of bone marrow nucleated cells, and G-banding analysis revealed a 46,XX,t (8;14), (q24;q32) karyotype in 4 of 20 cells analyzed. A biopsy specimen from an extramedullary lesion had a packed proliferation of aberrant plasmacytoid cells with positive IgH::MYC fusion signals on fluorescence in situ hybridization. The patient was diagnosed with symptomatic multiple myeloma and treated with the BLd regimen, which significantly reduced M protein levels. Extramedullary lesions were initially reduced, but increased again after four cycles. The lesions disappeared with subsequent EPOCH chemotherapy and radiation, and complete remission was confirmed. The patient was then treated with high-dose chemotherapy with autologous peripheral blood stem cell transplantation. Complete remission was maintained for over one year with lenalidomide maintenance therapy. A solitary IgH::MYC chromosomal translocation is extremely rare in multiple myeloma and may be associated with high tumor proliferative capacity, multiple extramedullary lesions, and poor prognosis. Combined therapeutic modalities with novel and conventional chemotherapy and radiation might be a promising treatment strategy for patients with this type of multiple myeloma.","PeriodicalId":93844,"journal":{"name":"[Rinsho ketsueki] The Japanese journal of clinical hematology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140873986","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}

Blood tests revealed hyperleukocytosis and bone marrow examination showed major BCR::ABL1 fusion, leading to the diagnosis of chronic myelogenous leukemia (CML). Due to intolerance, the tyrosine kinase inhibitor (TKI) was changed from imatinib to dasatinib to nilotinib. The patient achieved molecular remission but became markedly short in stature, measuring 129.3 cm (height standard deviation score [SDS] -3.3) at the age of 12. TKI therapy was discontinued at age 12 years and 10 months, which was 9 years and 8 months after the start of TKI and 1 year and 6 months after achievement of MR4.0, as discontinuation before epiphyseal closure would not improve short stature. At 2 years and 6 months after discontinuation, the patient's height improved to 156.1 cm (SDS-2.0) without relapse. Growth suppression by TKIs is a problem in the management of pediatric CML. This case illustrates how improvement in severe short stature can be achieved by discontinuing TKI therapy before epiphyseal closure.","PeriodicalId":93844,"journal":{"name":"[Rinsho ketsueki] The Japanese journal of clinical hematology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140867879","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}

Recently, immunotherapy using both bispecific antibodies (BsAb) and chimeric antigen receptor T cells (CAR-T cells) has induced further anti-myeloma responses. Different agents must be combined to overcome the heterogeneity of myeloma cell clones, and new modalities for the treatment of refractory myeloma must also be developed to strengthen therapeutic effects. We have developed a novel BiTE (bispecific T-cell engager)-based modality, referred to as bridging-BiTE (B-BiTE). B-BiTE is able to bind to both an Fc domain of a human immunoglobulin G monoclonal antibody (mAb) and the human CD3 molecule. This enables rapid generation of a mAb/B-BiTE complex and safely induces dual-lymphoid activation of both human T cells and NK cells against myeloma cells. Importantly, sequential immunotherapy using two different mAb/B-BiTE complexes can produce deep and durable anti-myeloma responses. To further advance treatment of multiple myeloma, it is important to determine how to combine and sequence immunotherapy with other agents while considering management of unique adverse events caused by activated immune cells.","PeriodicalId":93844,"journal":{"name":"[Rinsho ketsueki] The Japanese journal of clinical hematology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141201489","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}
