Abstract

More information is needed about genetic factors that initiate development of pancreatic intraepithelial neoplasms-the most common precursors of pancreatic ductal adenocarcinoma. We show that more than 99% of the earliest-stage, lowest-grade, pancreatic intraepithelial neoplasm-1 lesions contain mutations in KRAS, p16/CDKN2A, GNAS, or BRAF. These findings could improve our understanding of the development and progression of these premalignant lesions.

  • KRAS mutations may be acquired as later events during systemic treatment for metastatic disease and have been found as subclonal genetic alterations in a subset of CRC patients.

    “however, may be acquired as later events during systemic treatment for metastatic disease and have been found as subclonal genetic alterations in a subset of CRC patients ([25-27])”

    From Anti-tumor efficacy of a potent and selective non-covalent KRASG12D inhibitor (2022) · cites this paper as [26]

    The Abstract reports that KRAS mutations occur in only a fraction of cells in early pancreatic intraepithelial neoplasia, supporting the subclonal aspect. It does not establish that KRAS mutations arise during systemic treatment for metastatic disease or that this occurs in colorectal cancer patients. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • KRAS mutations are often a founder genetic event involved in the pathogenesis of PDAC and are consistently found in precancerous pancreatic intraepithelial neoplasms.

    “First, KRAS mutations are often a founder genetic event involved in the pathogenesis of PDAC and are consistently found in precancerous pancreatic intraepithelial neoplasms”

    From Anti-tumor efficacy of a potent and selective non-covalent KRASG12D inhibitor (2022) · cites this paper as [26]

    The paper reports KRAS mutations in 163 of 169 PanINs (96.4%), supporting their frequent presence in these precancerous lesions. It proposes that KRAS mutations can initiate PanIN development, but calls this a hypothesis rather than establishing that they are often a founder event in PDAC. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • KRAS mutations are observed in most low-grade PanINs and IPMNs, suggesting KRAS is the initiating genetic event in exocrine neoplasia.

    “KRAS mutations are observed in most low-grade PanINs and IPMNs, suggesting KRAS is the initiating genetic event driving exocrine neoplasia46,47.”

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.
