T-cell receptor (TCR) therapies are a promising modality for the treatment of cancers, with significant efforts being directed towards acute myeloid leukaemia (AML), a particularly challenging disease. Chimeric antigen receptor (CAR) T-cells targeting single surface antigens have shown remarkable efficacy for B-cell lymphoblastic leukaemia, lymphomas and multiple myeloma. However, AML presents formidable obstacles to the effectiveness of CAR T-cells due to the widespread expression of heterogenous leukaemia immunophenotypes and surface antigen targets additionally present on normal myeloid cells.

The role of ICB in nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) is not established. To gain insights into its potential in NLPHL, we compared TME and peripheral blood signatures between HLs using an integrative multiomic analysis.

MRD by multiparametric flow cytometry (MFC-MRD) utilises the leukaemia-associated immunophenotype (LAIP) and difference from normal (DfN) strategies to identify the leukaemic clone. Difficulties arise when the LAIP overlaps with normal regeneration, there is clonal evolution, or when the abnormal clone population is exceptionally small e.

Methods: We performed an international multicenter retrospective study of patients with RT who received CAR-T.
