Fibrosis regression in chronic liver disease: The pathologist's view.

Significant liver fibrosis can completely disappear or be substantially remodelled after removal of the initiating agent or effective therapy, including documented reversal of established cirrhosis.

• Why it matters: Existing fibrosis-regression studies rely on semiquantitative staging systems designed for progressive disease, leaving regressive histological features and a “point of no return” in advanced fibrosis insufficiently characterized.
• What they did: The review highlights limitations of current histological assessment across common chronic liver diseases and notes that the Beijing P-I-R classification has been validated only in viral liver disease.
• The result: It argues for improved, more nuanced assessment of regression and for identifying a “point of no return,” potentially supported by artificial intelligence for liver biopsy evaluation.
