Pre-LT findings in bile duct brush cytology and/or biopsy of low-grade dysplasia (LGD) and high-grade dysplasia (HGD) were compared with histological findings in the explanted livers and survival rates were assessed.</div></div><div><h3>Results</h3><div>Bile duct dysplasia, low-grade (LGD) or high-grade (HGD), was the primary LT indication in 17% (88/512). Among individuals transplanted for LGD, only 10% (3/29) had HGD or CCA in the explant, compared to 48% (28/59) in the HGD group. No neoplasia was found in 42% (12/29) of LGD and 24% (14/59) of HGD cases, meaning nearly one-third of patients transplanted for suspected bile duct dysplasia had no histological evidence of neoplasia in the explant.

LT appears more clearly justified in accurately diagnosed HGD, given its strong association with early malignancy and the poor prognosis of advanced CCA.</div></div><div><h3>Impact and implications</h3><div>Individuals with primary sclerosing cholangitis (PSC) are at increased risk of developing bile duct cancer. In precancerous stages (bile duct dysplasia), liver transplantation (LT) may prevent progression to advanced, incurable cancer.

HBV infection with both culture-derived and patient-derived clinical isolates (genotypes A-E) significantly increased luciferase activity (<em>p &lt;</em>0.0001). Treatment with HBx inhibitors (siRNA, specific HBx inhibitors), as well as IFNα reduced luciferase production (<em>p &lt;</em>0.0001). In contrast, antivirals that do not interfere with protein production (tenofovir), or viral entry (bulevirtide) showed no effect (<em>p &lt;</em>0.05), underscoring the specificity of the system for identifying compounds that inhibit protein production and/or HBx function.
