Abstract

The diverse malignant, stromal, and immune cells in tumors affect growth, metastasis, and response to therapy. We profiled transcriptomes of ∼6,000 single cells from 18 head and neck squamous cell carcinoma (HNSCC) patients, including five matched pairs of primary tumors and lymph node metastases. Stromal and immune cells had consistent expression programs across patients. Conversely, malignant cells varied within and between tumors in their expression of signatures related to cell cycle, stress, hypoxia, epithelial differentiation, and partial epithelial-to-mesenchymal transition (p-EMT). Cells expressing the p-EMT program spatially localized to the leading edge of primary tumors. By integrating single-cell transcriptomes with bulk expression profiles for hundreds of tumors, we refined HNSCC subtypes by their malignant and stromal composition and established p-EMT as an independent predictor of nodal metastasis, grade, and adverse pathologic features. Our results provide insight into the HNSCC ecosystem and define stromal interactions and a p-EMT program associated with metastasis.

  • EMT-like TSK cells lacked expression of classic EMT transcription factors.

    “Similar to a previous study of oropharyngeal SCC (Puram et al., 2017), EMT-like TSK cells lacked expression of classic EMT transcription factors (TFs)”

    From Multimodal Analysis of Composition and Spatial Architecture in Human Squamous Cell Carcinoma (2020) · cites this paper as Puram et al., 2017

    The Results section (‘A partial EMT program in HNSCC’) reports no detected expression of several classical EMT transcription factors in the source paper’s p-EMT cells. It explicitly identifies an exception: SNAIL2 was detected in 70% of HNSCC cells. The unqualified claim that classic EMT transcription factors were absent omits that exception. (LLM, conf=0.86)

  • Single-cell sequencing indicates common traits are preserved across tissues and species.

    “While single-cell sequencing indicates common traits are preserved49–51, it will become increasingly pressing to define common and specific effects of CAFs.”

    From A framework for advancing our understanding of cancer-associated fibroblasts (2020) · cites this paper as [49]

    The Results section reports that fibroblast expression states were reproducibly detected across HNSCC tumors. It also describes broad similarity between primary tumors and matched lymph-node metastases, though with differences in fibroblast subsets. These findings support common traits across the studied tumors and sites, but not preservation across species; no page numbers are available in our copy. (LLM, conf=0.87)

  • There is a recurrent observation of distinct CAFs exhibiting either a matrix-producing contractile phenotype or an immunomodulating secretome, often termed myoCAFs and iCAFs.

    “Nonetheless, there is a recurrent observation of distinct CAFs exhibiting either a matrix-producing contractile phenotype or an immunomodulating secretome — often termed ‘myoCAFs’ and ‘iCAFs’, with the prefixes alluding to a myofibroblast phenotype and regulation of inflammation, respectively.”

    From A framework for advancing our understanding of cancer-associated fibroblasts (2020) · cites this paper as [49]

    The Results section, “Landscape of expression heterogeneity in head and neck cancer” (page not provided), describes reproducible fibroblast subsets, including contractile myofibroblasts and CAFs expressing ligands and extracellular-matrix genes. It does not characterize the CAF subsets as an immunomodulating secretome or call them myoCAFs and iCAFs; it calls the two CAF subtypes CAF1 and CAF2. (LLM, conf=0.85)

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.
