Nivolumab with or without Ipilimumab Combined with Stereotactic Body Radiotherapy in Patients with Metastatic Biliary Tract Cancer: A Randomized Phase 2 Study.

Purpose: The purpose of this study was to evaluate the clinical benefits of nivolumab with/without ipilimumab combined with stereotactic body radiotherapy (SBRT) in patients with pretreated metastatic biliary tract cancer (mBTC).

Patients And Methods: The study was a phase 2 randomized trial with Simon's optimal two-stage design requiring 36 evaluable patients per group after second stage. Sixty-one patients were included from September 2018 to January 2022 and randomized (1:1) to receive SBRT (15 Gy × 1 on day 1 to a primary or metastatic lesion) and nivolumab (3 mg/kg intravenously on day 1 and every 2 weeks) with/without ipilimumab (1 mg/kg intravenously on day 1 and every 6 weeks).

Prognostic genomic alterations in patients undergoing liver resection for hepatocellular carcinoma.

Introduction: Genetic mutations and amplifications found in hepatocellular carcinoma (HCC) have a potentially prognostic impact. The aim of this study was to investigate the prognostic value of mutations and amplifications in HCC from patients that were liver resected.

Methods: Patients liver resected for HCC at Copenhagen University Hospital Rigshospitalet between May 2014 and January 2018 were included.

Hepatic granulomas following liver transplantation: A retrospective survey, and analysis of possible microbiological etiology.

Background: Liver granulomas have always been a diagnostic challenge for pathologists. They have been described in up to 15% of liver biopsies and can also be seen in liver allograft biopsy specimens, but there is a paucity of information regarding the prevalence and associated etiologic factors of granulomas in liver transplanted patients. The aim of this study is to shed light on the etiology of liver granulomas.

Salvage therapies of autoimmune hepatitis limit proinflammatory immune cells while sparing regulatory T cells.

Background: Autoimmune hepatitis (AIH) can be clinically controlled by first-line immunosuppressive therapy in the majority of patients. However, a selective decrease in intrahepatic regulatory T cells (Treg) was observed with immunosuppressive therapy, which was even more pronounced in patients with incomplete responses than in patients who achieved biochemical remission. The effects of salvage therapies on the number of intrahepatic T and B cells, including Treg, are unclear.
