Abstract

Chordomas are rare tumors of notochordal origin, most commonly arising in the sacrum or skull base. Chordomas are considered insensitive to conventional chemotherapy, and their rarity complicates running timely and adequately powered trials to identify effective treatments. Therefore, there is a need for discovery of novel therapeutic approaches. Patient-derived organoids can accelerate drug discovery and development studies and predict patient responses to therapy. In this proof-of-concept study, we successfully established organoids from seven chordoma tumor samples obtained from five patients presenting with tumors in different sites and stages of disease. The organoids recapitulated features of the original parent tumors and inter- as well as intrapatient heterogeneity. High-throughput screenings performed on the organoids highlighted targeted agents such as PI3K/mTOR, EGFR, and JAK2/STAT3 inhibitors among the most effective molecules. Pathway analysis underscored how the NF-κB and IGF-1R pathways are sensitive to perturbations and potential targets to pursue for combination therapy of chordoma.

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

  • Patient-derived organoids can generate xenografts, confirm their tumorigenic capacity, and recapitulate the histology of parental tumors.

    “Patient-derived organoids can also generate xenografts, confirm their tumorigenic capacity and recapitulate the histology of parental tumors15,55.”

    From Organoids (2022) · cites this paper as [15]

    The Results section reports that the chordoma organoids retained the immunohistopathological characteristics of their parental tumors, supporting the histology portion of the claim. The Introduction and Discussion mention chordoma xenograft models, but do not report generating xenografts from these organoids or confirming their tumorigenic capacity in vivo. (LLM, conf=0.90)

    Experimental — accuracy not yet measured
  • Most mutations and CNVs are preserved in late-passage lung cancer organoids, while de novo mutations can be attributed to sub-clonal expansion of small subsets of cells from the original tumor.

    “Most mutations and CNVs are are preserved in the late passage of lung cancer organoids, while de novo mutations can be attributed to the sub-clonal expansion of small subsets of cells present in the tumor of origin15.”

    From Organoids (2022) · cites this paper as [15]

    The Abstract and Discussion describe chordoma organoids that recapitulate features of their parent tumors, but do not address late-passage lung cancer organoids. Searches for mutations, CNVs, and sub-clonal expansion found no passage supporting the claimed genetic preservation or explanation for de novo mutations. Page numbers were not available in our copy. (LLM, conf=0.77)

    Experimental — accuracy not yet measured
  • Several studies have found concordance between tumor organoids and parent tissue in mutations and copy number variations.

    “Several studies have shown concordance of organoids and parent tissue in terms of mutations and copy number variations (CNV)15,127.”

    From Organoids (2022) · cites this paper as [15]

    The Results section reports that chordoma organoids recapitulated the parent tumors’ immunohistopathological features, and the Discussion describes similar staining and growth profiles. Neither passage establishes concordance in mutations or copy number variations; searches for those genomic measures found no supporting passage in our copy. (LLM, conf=0.75)

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.
