Multi-Omics Classification of Intrahepatic Cholangiocarcinoma: A Systematic Review and Meta-Analysis.

Intrahepatic cholangiocarcinoma (ICC) is a heterogeneous disease characterized by a dismal prognosis. Various attempts have been made to classify ICC subtypes with varying prognoses, but a consensus has yet to be reached. This systematic review aims to gather relevant data on the multi-omics-based ICC classification.

Percutaneous ablation in perivascular-HCC: impact of liver parenchyma and characteristics of vascular structures on the outcomes.

Aim: Percutaneous radiofrequency ablation (RFA) is a standard treatment for small-HCC (<3 cm). However, some features such as proximity to intrahepatic vascular structures (perivascular location) seem to be related to short- and long-term outcomes. The aims of the study were to investigate the features related to ablation success and local tumor progression (LTP) in patients submitted to percutaneous ablation for perivascular-HCC.

Radiomics of Intrahepatic Cholangiocarcinoma and Peritumoral Tissue Predicts Postoperative Survival: Development of a CT-Based Clinical-Radiomic Model.

Background: For many tumors, radiomics provided a relevant prognostic contribution. This study tested whether the computed tomography (CT)-based textural features of intrahepatic cholangiocarcinoma (ICC) and peritumoral tissue improve the prediction of survival after resection compared with the standard clinical indices.

Methods: All consecutive patients affected by ICC who underwent hepatectomy at six high-volume centers (2009-2019) were considered for the study.

The Role of Three-Dimensional Modeling to Improve Comprehension of Liver Anatomy and Tumor Characteristics for Medical Students and Surgical Residents.

Objective: Studying liver anatomy can be challenging for medical students and surgical residents due to its complexity. Three-dimensional visualization technology (3DVT) allows for a clearer and more precise view of liver anatomy. We sought to assess how 3DVT can assist students and surgical residents comprehend liver anatomy.

Transjugular intrahepatic portosystemic shunt followed by splenectomy for complicated hepatosplenic schistosomiasis: a case report and review of the literature.

Hepatosplenic schistosomiasis is a complex clinical condition caused by the complications of chronic infection with Schistosoma species that cause intestinal schistosomiasis. Hepatosplenic schistosomiasis derives from the fibrotic reaction stimulated around parasite eggs that are transported by the mesenteric circulation to the liver, causing periportal fibrosis. Portal hypertension and variceal gastrointestinal bleeding are major complications of hepatosplenic schistosomiasis.

Radiomics preoperative-Fistula Risk Score (RAD-FRS) for pancreatoduodenectomy: development and external validation.

Background: Accurately predicting the risk of clinically relevant postoperative pancreatic fistula after pancreatoduodenectomy before surgery may assist surgeons in making more informed treatment decisions and improved patient counselling. The aim was to evaluate the predictive accuracy of a radiomics-based preoperative-Fistula Risk Score (RAD-FRS) for clinically relevant postoperative pancreatic fistula.

Methods: Radiomic features were derived from preoperative CT scans from adult patients after pancreatoduodenectomy at a single centre in the Netherlands (Amsterdam, 2013-2018) to develop the radiomics-based preoperative-Fistula Risk Score.

Radiomic Analysis of Intrahepatic Cholangiocarcinoma: Non-Invasive Prediction of Pathology Data: A Multicenter Study to Develop a Clinical-Radiomic Model.

Standard imaging cannot assess the pathology details of intrahepatic cholangiocarcinoma (ICC). We investigated whether CT-based radiomics may improve the prediction of tumor characteristics. All consecutive patients undergoing liver resection for ICC (2009-2019) in six high-volume centers were evaluated for inclusion.

The Brescia Internationally Validated European Guidelines on Minimally Invasive Pancreatic Surgery (EGUMIPS).

Objective: To develop and update evidence-based and consensus-based guidelines on laparoscopic and robotic pancreatic surgery.

Summary Background Data: Minimally invasive pancreatic surgery (MIPS), including laparoscopic and robotic surgery, is complex and technically demanding. Minimizing the risk for patients requires stringent, evidence-based guidelines.

Current Role and Future Perspectives of Immunotherapy and Circulating Factors in Treatment of Biliary Tract Cancers.

Biliary tract cancers (BTCs) are a heterogenous group of malignancies arising from the epithelial cells of the biliary tree and the gallbladder. They are often locally advanced or already metastatic at the time of the diagnosis and therefore prognosis remains dismal. Unfortunately, the management of BTCs has been limited by resistance and consequent low response rate to cytotoxic systemic therapy.

Short and long-term outcomes after minimally invasive liver resection for single small hepatocellular carcinoma: An analysis of 714 patients from the IGoMILS (Italian group of minimally invasive liver surgery) registry.

Background: Widespread use of minimally invasive liver surgery (MILS) contributed to the reduction of surgical risk of liver resection for hepatocellular carcinoma (HCC). Aim of this study was to analyze outcomes of MILS for single ≤3 cm HCC.

Methods: Patients who underwent MILS for single ≤3 cm HCC (November 2014 - December 2019) were identified from the Italian Group of Minimally Invasive Liver Surgery (IGoMILS) Registry.

The Tumor Microenvironment Drives Intrahepatic Cholangiocarcinoma Progression.

Intrahepatic cholangiocarcinoma (iCCA) is a highly aggressive cancer with limited therapeutic options and short overall survival. iCCA is characterized by a strong desmoplastic reaction in the surrounding ecosystem that likely affects tumoral progression. Overexpression of the Notch pathway is implicated in iCCA development and progression.

Ablation Difficulty Score: Proposal of a new tool to predict success rate of percutaneous ablation for hepatocarcinoma.

Purpose: Identify the factors related to failure ablation after percutaneous ultrasound guided single electrode radiofrequency ablation (RFA) for hepatocarcinoma (HCC) and propose a score for improving patient selection and treatment allocation.

Methods: From 2010 to 2020 585 HCC nodules treated with RFA were prospectively collected. Ablation Difficulty Score (ADS) was built-up according to clinical and radiological factors related to failure ablation identified by Cox-logistic regression analysis.

Structured Reporting of Computed Tomography and Magnetic Resonance in the Staging of Pancreatic Adenocarcinoma: A Delphi Consensus Proposal.

Background: Structured reporting (SR) in radiology has been recognized recently by major scientific societies. This study aims to build structured computed tomography (CT) and magnetic resonance (MR)-based reports in pancreatic adenocarcinoma during the staging phase in order to improve communication between the radiologist and members of multidisciplinary teams.

Materials And Methods: A panel of expert radiologists, members of the Italian Society of Medical and Interventional Radiology, was established.

How to perform shear wave elastography. Part II.

Recently a series of papers was introduced describing on "how to do" certain techniques. More specifically we published on how to perform strain imaging using the transcutaneous and endoscopic ultrasound approach and shear wave elastography (SWE). In the first part we describe how to optimize the examination technique, discussing normal values, pitfalls, artefacts and specific tips for applying SWE to specific organs (liver, breast, thyroid, salivary glands) as part of a diagnostic US examination.

An Overview of Artificial Intelligence Applications in Liver and Pancreatic Imaging.

Background: Synovial sarcoma (SS) is a rare soft tissue tumor. Among different anatomical locations where it can be found, gastric localization is a very uncommon one. Based on soft tissue sarcoma guidelines, complete tumor excision is considered the main treatment approach.

Dose-escalation strategy in refractory metastatic colorectal cancer: A change in terms of cost-effectiveness.

The analysis was conducted to assess the pharmacological costs of regorafenib and trifluridine/tipiracil in the treatment of refractory metastatic colorectal cancer (mCRC). Pivotal phase III randomized controlled trials (RCTs) of regorafenib and trifluridine/tipiracil in the treatment of refractory mCRC were considered. We have also considered the ReDOS trial, in order to verify if the dose-escalation strategy (practice changing for regorafenib) could influences the results.

CIDP, CMT1B, or CMT1B plus CIDP?

Charcot-Marie-Tooth disease type 1 (CMT1) and chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) have distinct clinical and neurophysiological features that result from dysmyelination in CMT1 and macrophage-mediated segmental demyelination in CIDP. CMT1 may occur in genetically isolated cases with atypical presentations that converge phenotypically with CIDP; in rare cases, however, CMT1 may be complicated by superimposed CIDP. We report the case of a patient harboring a de novo heterozygous null mutation of the myelin protein zero (MPZ) gene and affected by subclinical CMT1B who became symptomatic due to superimposed CIDP.
