Digital Spatial Profiling of tumor microenvironment of classic Hodgkin lymphoma.

Project description:Classic Hodgkin lymphoma (CHL) harbors a small number of Hodgkin-Reed-Sternberg (HRS) cells scattering among numerous lymphocytes. HRS cells are surrounded by distinct CD4+ T cells in a rosette-like manner. These CD4+ T cell rosettes play an important role in tumor microenvironment (TME) of CHL. To elucidate the interaction between HRS cells and CD4+ T cell rosettes, we performed digital spatial profiling (DSP) and compared gene expression profile between CD4+ T cell rosettes and other CD4+ cells separated from HRS cells. programed cell death-1 (PD-1) and tumor necrosis factor receptor superfamily member (TNFRSF) 4 were significantly highly expressed in CD4+ T cell rosettes than others. Immunohistochemistry confirmed PD-1 and TNFRSF4-expressing CD4+ T cell rosettes. This study introduced the new pathological approach to TME and provided deeper insight to CD4+ T cells in CHL.

Digital Spatial Profiling of CD4+ cells in classic Hodgkin lymphoma.

Project description:Classic Hodgkin lymphoma (CHL) harbors a small number of Hodgkin-Reed-Sternberg (HRS) cells scattered among numerous lymphocytes. HRS cells are surrounded by distinct CD4+ T cells in a rosette-like manner. These CD4+ T cell rosettes play an important role in the tumor microenvironment (TME) of CHL. To elucidate the interaction between HRS cells and CD4+ T cell rosettes, we completed digital spatial profiling to compare the gene expression profiles of CD4+ T cell rosettes and other CD4+ T cells separated from the HRS cells. Tumor necrosis factor receptor superfamily member (TNFRSF) 4 or OX40 showed significantly higher expression in CD4+ T cell rosettes when compared with other CD4+ T cells. Programed cell death-1 (PD-1) and cytotoxic T lymphocyte associated protein 4 (CTLA-4) tended to be highly expressed in CD4+ T cell rosettes compared to other CD4+ T cells. Immunohistochemistry revealed variable expression of these immune checkpoint molecules in the CD4+ T cell rosettes. This study introduced a new pathological approach to the TME and provided deeper insight into CD4+ T cells in CHL.

Circulating tumor DNA for monitoring classic Hodgkin lymphoma patients: correlation with FDG-PET/CT

Project description:Circulating tumor DNA (ctDNA) as a biomarker of disease activity in classic Hodgkin lymphoma (cHL) patients are still not well-defined. By profiling primary tumors and ctDNA, we identified common variants between primary tumors and longitudinal plasma samples in most of the cases, confirming high PBatial and temporal heterogeneity. Though ctDNA analyses mirrored HRS cell genetics overall, the prevalence of variants shows that none of them can be used as a single biomarker. Conversely, the estimation of hGE/mL, based in total ctDNA quantification, reflects disease activity and is almost perfectly correlated with standard parameters such as PET/CT that are associated with refractoriness.

Spatial tumor microenvironment characterization and outcome of relapsed/refractory classic Hodgkin lymphoma

Project description:About half of relapsed or refractory classic Hodgkin lymphoma (r/r CHL) patients succumb to their disease after high dose chemotherapy followed by autologous stem cell transplantation (HDT/ASCT). Here, we aimed at describing spatially resolved tumor microenvironment (TME) ecosystems to establish novel biomarkers associated with treatment failure in r/r CHL.
