Abstract

HLA-C*08:02-restricted tumor-infiltrating lymphocytes that were composed of four different T-cell clonotypes that specifically targeted KRAS G12D. However, one of these lesions had progressed on evaluation 9 months after therapy. The lesion was resected and found to have lost the chromosome 6 haplotype encoding the HLA-C*08:02 class I major histocompatibility complex (MHC) molecule. The loss of expression of this molecule provided a direct mechanism of tumor immune evasion. Thus, the infusion of CD8+ cells targeting mutant KRAS mediated effective antitumor immunotherapy against a cancer that expressed mutant KRAS G12D and HLA-C*08:02.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Adoptive T-cell therapy targeting mutant KRAS fragments has shown efficacy in colon cancer and NSCLC patients with mutant KRAS G12D and HLA-C*08:02 expression.

    “This approach has shown efficacy in colon cancer and NSCLC patients with mutant KRAS G12D and HLA-C*08:02 expression [88].”

    From KRAS: Biology, Inhibition, and Mechanisms of Inhibitor Resistance (2024) · cites this paper as [88]

    The Case Report identifies one patient with metastatic colorectal cancer, and the Clinical Evaluation reports regression of her lung metastases after therapy. The paper does not report efficacy in patients with primary NSCLC; lung metastases from colorectal cancer are not NSCLC. Page numbers were not available in our copy. (LLM, conf=0.91)

  • Tumors with mutant KRAS can express neoantigen fragments containing the oncogenic driver mutation on the MHC.

    “Tumors with mutant KRAS can express neoantigen fragments containing the oncogenic driver mutation on the major histocompatibility complex [88,89].”
  • CD8+ tumor-infiltrating lymphocytes and TCRs in CD4+ T cells specifically recognize KRAS-related mutations and can be used to engineer T cells.

    “CD8+ TILs and TCRs in CD4+ T cells have been found to specifically recognize KRAS-related mutations, which can be further used to engineer T cells.604,605”
  • Peptides derived from KRASG12 variants and from KRASQ61H/L/R are presented on the surface of malignant cells by various MHC I (HLA-A) molecules.

    “As noted above, peptides derived from KRASG12 variants193,194, and also from KRASQ61H/L/R (ref.198), have been demonstrated to be presented on the surface of malignant cells by various MHC I (HLA-A) molecules.”
  • Adoptive cell therapy with these specific TILs caused regression of all seven pulmonary metastases in a patient with KRASG12D-mutant colorectal cancer.

    “ACT with these specific TILs resulted in regression of all seven pulmonary metastases in a patient with KRASG12D-mutant CRC from whom they had been isolated193.”

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.
