Summary

Hepatocellular adenomas (HCA) are tumors rare benign hepatic infections that develop on a liver normal and in young women taking a estrogen-based contraception. The main molecular subgroup of AHCs is the AHC subgroup inflammatory, which are associated with a risk of bleeding from the tumor and malignant transformation. Therefore, most of women with large inflammatory AHC (\>5 cm) require liver resection which can be associated with morbidity and aesthetic problems, and rarely to mortality. On the basis of the knowledge of the molecular classification of AHCs humans and preclinical data testing the JAK1/2 inhibitors, we hypothesize that a short duration of treatment with the inhibitor of JAK1/2 (baricitinib) may be effective in patients with large inflammatory AHC size.

Detailed description

Hepatocellular adenomas (HCA) are tumors rare benign hepatic infections that develop on a liver normal and in young women taking a estrogen-based contraception. The main molecular subgroup of AHCs is the AHC subgroup inflammatory, characterized by activation of the pathway JAK/STAT due to mutations in IL6ST, STAT3, FRK, JAK1 or GNAS, with inflammatory infiltrates at histology. Hepatocellular adenomas are associated with a risk of bleeding from the tumor and malignant transformation. Therefore, most of women with large inflammatory AHC (\>5 cm) require liver resection which can be associated with morbidity and aesthetic problems, and rarely to mortality. On the basis of the knowledge of the molecular classification of AHCs humans and preclinical data testing the JAK1/2 inhibitors, we hypothesize that a short duration of treatment with the inhibitor of JAK1/2 (baricitinib) may be effective in patients with large inflammatory AHC size.

Conditions

• Inflammatory Hepatocellular Adenoma

Interventions

Type	Name	Description
DRUG	Baricitinib	An ancillary study will be performed in a subgroup of 12 patients to assess the variation of the results of PET-CT with 18FDG from baseline to 3 months. The variation of tumor features assessed by PET-CT with 18FDG after three months of treatment, will be assessed. The median value of the SUV max and tumor to non-tumor ratio of the SUV max value for each HCA lesion between the PET CT with 18FDG performed at baseline and after 3 months of treatment will be assessed.
