Immune checkpoint inhibitors (ICI) have led to breakthrough improvements in the management of malignancy including hepatocellular (HCC) and biliary tract cancer, improving decades-old standards of care and increasing patient survival. In both liver tumour types, which commonly arise in the context of liver inflammation and underlying functional impairment, the lack of validated predictors of response underscores the need to balance predicted gains in survival with risk of treatment-related hepatoxicity and decompensation of underlying chronic liver disease.In addition, the liver is implicated in the toxicity associated with ICI therapy for non-liver cancers, which exhibits a high degree of variability in presentation and severity.

Introduction: In recent years, caesarean section (CS) rate has risen worldwide. Complications associated with CS scars have risen too, such as scar dehiscences and uterine ruptures. Uterine healing is a complex phenomenon still poorly understood.

Article Synopsis
  • Liver resection is effective for small hepatocellular carcinoma, but many patients face recurrence, making it important to identify those at a higher risk.
  • A new deep learning algorithm using ResNet34 analyzed 680 whole slide images of liver specimens, achieving high accuracy (0.864 for patches, 0.823 for whole slides) in identifying risk indicators associated with HCC recurrence.
  • Validated on an external dataset, the model showed promise in predicting recurrence by correlating pejorative architectural features with critical histological indicators like microvascular invasion, potentially paving the way for a comprehensive predictive tool for early post-resection recurrence.

Background & Aims: The diagnosis of primary liver cancers (PLCs) can be challenging, especially on biopsies and for combined hepatocellular-cholangiocarcinoma (cHCC-CCA). We automatically classified PLCs on routine-stained biopsies using a weakly supervised learning method.

Method: We selected 166 PLC biopsies divided into training, internal and external validation sets: 90, 29 and 47 samples, respectively.

Background: The occurrence of acute liver failure (ALF) in pregnant women due to an etiology unrelated to pregnancy (pregALF) that leads to liver transplantation (LT) has rarely been reported. The objective was to report the outcome of pregnant women and fetus and propose a strategy for the timing of delivery and of LT in these patients.

Methods: Five consecutive pregnant patients with ALF were admitted to our center between 1986 and 2018 and underwent an LT.

Purpose: Evaluation of perfusion CT and dual-energy CT (DECT) quantitative parameters for predicting microvascular invasion (MVI) of hepatocellular carcinoma (HCC) prior to surgery.

Methods: This prospective single-center study included fifty-six patients (44 men; median age 67; range 31-84) who provided written informed consent. Inclusion criteria were (1) treatment-naïve patients with a diagnosis of HCC, (2) an indication for hepatic resection, and (3) available arterial DECT phase and perfusion CT (GE revolution HD-GSI).

Objectives: To share our experience with digital slide telepathology for intraoperative frozen section consultations (IOCs) and to describe its evolution over time by reporting performance metrics and addressing organizational and economic aspects.

Methods: Since 2013, a technician has been alone at the surgical site. At the other site, the pathologist opens the digital slide from a local server via the intranet.

Background & Aims: Severe acute liver injury is a grave complication of exertional heatstroke. Liver transplantation (LT) may be a therapeutic option, but the criteria for LT and the optimal timing of LT have not been clearly established. The aim of this study was to define the profile of patients who require transplantation in this context.

Background: 18F-FDG-PET scan positivity correlates with poor prognosis in neuroendocrine neoplasms (NEN). Glucose transporter 1 (GLUT1) and carbonic anhydrase 9 (CA9) are markers of aggressiveness in tumors. Together with von Hippel-Lindau protein (pVHL), they are involved in tumor cell metabolism via the hypoxia-inducible factor signaling pathway.

Background: Idiopathic pulmonary fibrosis (IPF) is a devastating disease characterized by an unpredictable course. Prognostic markers and disease activity markers are needed. The purpose of this single-center retrospective study was to evaluate the prognostic value of lung fluorodeoxyglucose ([F]-FDG) uptake assessed by standardized uptake value (SUV), metabolic lung volume (MLV) and total lesion glycolysis (TLG) in patients with IPF.

Background: Drug reaction with eosinophilia and systemic symptoms (DRESS) is a rare severe adverse drug-induced reaction with multiorgan involvement. The outcome and prediction of those patients who develop severe acute liver injury (sALI) or acute liver failure (ALF) remain little known.

Methods: A multicenter retrospective study of patients admitted with a diagnosis of DRESS-related sALI or ALF.
