Abstract

Objective: Pancreatic ductal adenocarcinoma (PDA) is characterised by stromal desmoplasia and vascular dysfunction, which critically impair drug delivery. This study examines the role of an abundant extracellular matrix component, the megadalton glycosaminoglycan hyaluronan (HA), as a novel therapeutic target in PDA. Methods: Using a genetically engineered mouse model of PDA, the authors enzymatically depleted HA by a clinically formulated PEGylated human recombinant PH20 hyaluronidase (PEGPH20) and examined tumour perfusion, vascular permeability and drug delivery. The preclinical utility of PEGPH20 in combination with gemcitabine was assessed by short-term and survival studies. Results: PEGPH20 rapidly and sustainably depleted HA, inducing the re-expansion of PDA blood vessels and increasing the intratumoral delivery of two chemotherapeutic agents, doxorubicin and gemcitabine. Moreover, PEGPH20 triggered fenestrations and interendothelial junctional gaps in PDA tumour endothelia and promoted a tumour-specific increase in macromolecular permeability. Finally, combination therapy with PEGPH20 and gemcitabine led to inhibition of PDA tumour growth and prolonged survival over gemcitabine monotherapy, suggesting immediate clinical utility. Conclusions: The authors demonstrate that HA impedes the intratumoral vasculature in PDA and propose that its enzymatic depletion be explored as a means to improve drug delivery and response in patients with pancreatic cancer.

  • The high-density stroma of PDAC, comprised of CAFs, adipocytes, immune cells, ECs, nerve cells, PSCs, and ECM components like collagen and hyaluronic acid, constitutes up to 90% of tumor volume.

    “The high-density stroma of PDAC, comprised of cancer-associated fibroblasts (CAFs), adipocytes, immune cells, ECs, nerve cells, pancreatic stellate cells (PSCs), and extracellular matrix components (ECM) like collagen and hyaluronic acid, constitutes up to 90% of the tumor volume (Jacobetz et al., 2013; Poh and Ernst, 2021; Wu et al., 2021).”

    The Results section ('HA accumulates in PDA'; page unavailable) places hyaluronan predominantly in PDAC’s desmoplastic stroma, and the paper describes extensive extracellular-matrix deposits and tumour–fibroblast interactions. It does not establish the full list of stromal cell types or that stroma constitutes up to 90% of tumour volume. The 90% in Table 1 is the proportion of sampled PDAC cases with positive hyaluronan staining, not a volume measurement. (LLM, conf=0.88)

  • PDAC is marked by poor vascularization and abnormal leaky blood vessels, creating hypoxic conditions and elevated interstitial pressure.

    “Additionally, PDAC is marked by poor vascularization and abnormal leaky blood vessels, creating hypoxic conditions and elevated interstitial pressure (Jacobetz et al., 2013).”

    From Microphysiological systems as models for immunologically ‘cold’ tumors (2024) · cites this paper as Jacobetz et al., 2013

    The 'What is already known' section describes PDA as hypovascular, and the Introduction links poor tumour perfusion to interstitial hypertension. But the Results and Discussion report that untreated KPC tumour vessels have intact junctions and little leakage; leakiness increased after treatment. The cited passages do not establish the claimed hypoxic conditions or the proposed causal chain. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • CAF populations and their organization of tumor architecture vary across different tumor regions, creating sub-tumor microenvironments within patients.

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.
