Abstract

Liver cancer is the second leading cause of cancer mortality worldwide, causing more than 700,000 deaths annually. Because of the wide landscape of genomic alterations and limited therapeutic success of targeting tumor cells, a recent focus has been on better understanding and possibly targeting the microenvironment in which liver tumors develop. A unique feature of liver cancer is its close association with liver fibrosis. More than 80% of hepatocellular carcinomas (HCCs) develop in fibrotic or cirrhotic livers, suggesting an important role of liver fibrosis in the premalignant environment (PME) of the liver. Cholangiocarcinoma (CCA), in contrast, is characterized by a strong desmoplasia that typically occurs in response to the tumor, suggesting a key role of cancer-associated fibroblasts (CAFs) and fibrosis in its tumor microenvironment (TME). Here, we discuss the functional contributions of myofibroblasts, CAFs, and fibrosis to the development of HCC and CCA in the hepatic PME and TME, focusing on myofibroblast- and extracellular matrix–associated growth factors, fibrosis-associated immunosuppressive pathways, as well as mechanosensitive signaling cascades that are activated by increased tissue stiffness. Better understanding of the role of myofibroblasts in HCC and CCA development and progression may provide the basis to target these cells for tumor prevention or therapy.

  • Normal liver tissue has an elastic modulus around several kilo Pascal, whereas fibrosis causes increased tissue rigidity to up to 20 kPa.

    “Normal liver tissue has been reported to have an elastic modulus around several kilo Pascal, whereas fibrosis causes increased tissue rigidity to up to 20 kPa (Fig. 5L) (31, 32).”

    From Stiffness sensing via Piezo1 enhances macrophage efferocytosis and promotes the resolution of liver fibrosis (2024) · cites this paper as [31]

    Section 2.4 describes a stiffer tissue environment associated with extracellular-matrix changes, supporting the qualitative link between fibrosis and rigidity. Section 2.2 reports liver-stiffness measurements in kPa, but neither section gives an elastic modulus of several kPa for normal liver or a fibrotic value of up to 20 kPa. Page numbers are unavailable in our copy. (LLM, conf=0.85)

  • Hepatic fibrosis strongly correlates with hepatocellular carcinoma development, with 80-90% of hepatocellular carcinomas arising in fibrotic or cirrhotic livers.

    “Notably, there is a strong correlation between hepatic fibrosis and HCC development with 80–90% of HCCs developing in fibrotic or cirrhotic livers.”
  • Liver fibrosis often precedes HCC and is a risk factor for HCC in chronic liver disease.

    “Moreover, this antibiotic cocktail also reduced liver fibrosis 73, which often precedes HCC and represents a risk factor for HCC development in CLD70.”

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.
