Abstract

Only a subgroup of triple-negative breast cancer (TNBC) responds to immune checkpoint inhibitors (ICI). To better understand lack of response to ICI, we analyze 681 TNBCs for spatial immune cell contextures in relation to clinical outcomes and pathways of T cell evasion. Excluded, ignored and inflamed phenotypes can be captured by a gene classifier that predicts prognosis of various cancers as well as anti-PD1 response of metastatic TNBC patients in a phase II trial. The excluded phenotype, which is associated with resistance to anti-PD1, demonstrates deposits of collagen-10, enhanced glycolysis, and activation of TGFβ/VEGF pathways; the ignored phenotype, also associated with resistance to anti-PD1, shows either high density of CD163+ myeloid cells or activation of WNT/PPARγ pathways; whereas the inflamed phenotype, which is associated with response to anti-PD1, revealed necrosis, high density of CLEC9A+ dendritic cells, high TCR clonality independent of neo-antigens, and enhanced expression of T cell co-inhibitory receptors.

  • Spatial immunophenotypes assigned in triple-negative breast cancer through a spatial phenotype classifier predicted responses to treatment.

    “The spatial immunophenotypes were assigned in triple-negative breast cancer through a spatial phenotype classifier, which predicted responses to treatment.”
  • Integration of spatial phenotypes and immunity effectors panel with multiplexed immunofluorescent imaging, scRNA-seq and TCR repertoire analysis elucidated T cell evasion pathways in response to ICB in triple-negative breast cancer.

    “Another study integrated the spatial phenotypes and immunity effectors panel of Akoya Biosciences with multiplexed immunofluorescent imaging, scRNA-seq and TCR repertoire analysis to elucidate T cell evasion pathways in response to ICB in triple-negative breast cancer165.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
