Abstract

Therapies that target the programmed death-1 (PD-1) receptor have shown unprecedented rates of durable clinical responses in patients with various cancer types. One mechanism by which cancer tissues limit the host immune response is via upregulation of PD-1 ligand (PD-L1) and its ligation to PD-1 on antigen-specific CD8+ T cells (termed adaptive immune resistance). Here we show that pre-existing CD8+ T cells distinctly located at the invasive tumour margin are associated with expression of the PD-1/PD-L1 immune inhibitory axis and may predict response to therapy. We analysed samples from 46 patients with metastatic melanoma obtained before and during anti-PD-1 therapy (pembrolizumab) using quantitative immunohistochemistry, quantitative multiplex immunofluorescence, and next-generation sequencing for T-cell antigen receptors (TCRs). In serially sampled tumours, patients responding to treatment showed proliferation of intratumoral CD8+ T cells that directly correlated with radiographic reduction in tumour size. Pre-treatment samples obtained from responding patients showed higher numbers of CD8-, PD-1- and PD-L1-expressing cells at the invasive tumour margin and inside tumours, with close proximity between PD-1 and PD-L1, and a more clonal TCR repertoire. Using multivariate analysis, we established a predictive model based on CD8 expression at the invasive margin and validated the model in an independent cohort of 15 patients. Our findings indicate that tumour regression after therapeutic PD-1 blockade requires pre-existing CD8+ T cells that are negatively regulated by PD-1/PD-L1-mediated adaptive immune resistance.

  • Both PD-L1 expression and TMB fail to encapsulate various tumor microenvironmental features influencing ICI responses.

    “However, both PDL-1 expression and TMB fail to encapsulate various tumor microenvironmental features influencing ICI responses15–17.”

    From Predicting the tumor microenvironment composition and immunotherapy response in non-small cell lung cancer from digital histopathology images (2024) · cites this paper as [15]

    The paper’s Abstract and Extended Data Figures 4–5 link pembrolizumab response to CD8-cell location, PD-1/PD-L1 expression and T-cell repertoire features, supporting the point that PD-L1 expression alone does not capture every relevant microenvironmental feature. Our copy does not assess tumor mutational burden (TMB) or whether it fails to capture those features. (LLM, conf=0.87)

  • Pre-treatment CD8+ T cell presence is linked to responses to ICB and anti-PD-1 plus lenvatinib in HCC patients.

    “Pre-treatment CD8+ T cell presence is linked to responses to ICB and anti-PD-1 plus lenvatinib in HCC patients.”

    From Contrasting cytotoxic and regulatory T cell responses underlying distinct clinical outcomes to anti-PD-1 plus lenvatinib therapy in cancer (2025) · cites this paper as [4]

    The Abstract reports that higher pre-treatment CD8+ T-cell numbers were associated with response to PD-1 blockade. However, the patients had metastatic melanoma and received pembrolizumab; the paper does not establish this association for anti-PD-1 plus lenvatinib in HCC patients. (LLM, conf=0.91)

    Experimental — accuracy not yet measured
  • Higher density of CD8+ T cells was observed in baseline tumor samples of responders versus non-responders (p=0.04).

    “We compared the tumor-associated immune infiltrates via multi-parameter immunohistochemistry (IHC) and observed a higher density of CD8+ T cells in baseline samples of R versus NR (p=0.04), consistent with prior reports (Fig. 4A and fig. S18) (18, 37).”
  • Cancer cells can increase immune checkpoint molecules such as PD-L1, resulting in peripheral T cell exhaustion and inhibition of malignant cell apoptosis.

    “Additionally, cancer cells can increase immune checkpoint molecules such as PD-L1, resulting in peripheral T cell exhaustion and the inhibition of malignant cell apoptosis [85].”
  • PD-1 and CTLA-4 blockades are more effective in tumors infiltrated by T cells or with high mutation rates and thus more immunogenic prior to treatment.

    “Indeed, as mentioned in the previous section, both PD-1 and CTLA-4 blockades are more effective in tumors that are infiltrated by T cells or that have high mutation rates and are therefore more immunogenic prior to treatment (86–88).”

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.
