Is There a Role for Locoregional Therapies for Non-colorectal Gastrointestinal Malignancies?

The liver is the most common site of metastases from solid gastrointestinal tract tumors. Over the past few decades, the role of locoregional therapies, resection and thermal ablation, for neuroendocrine and colorectal liver metastases has been widely studied. However, for liver metastases originating from other gastrointestinal organs, the role of locoregional treatment remains unclear.

Cross-sectional imaging of pancreatic leak: a pictorial review.

Pancreatic leaks occur when a disruption in the pancreatic ductal system results in the leakage of pancreatic enzymes such as amylase, lipase, and proteases into the abdominal cavity. While often associated with pancreatic surgical procedures, trauma and necrotizing pancreatitis are also common culprits. Cross-sectional imaging, particularly computed tomography, plays a crucial role in assessing postoperative conditions and identifying both early and late complications, including pancreatic leaks.

Background: This study aimed to evaluate the outcomes of different treatments for patients with hepatocellular carcinoma (HCC) and macroscopic vascular invasion.

Methods: A systematic review and meta-analysis of comparative studies was performed to evaluate various treatment modalities for HCC with macroscopic vascular invasion, including liver resection (LR), liver transplantation (LT), transarterial chemoembolization (TACE), transarterial radioembolization (TARE), radiotherapy (RT), radiofrequency ablation (RFA), and antineoplastic systemic therapy (AnST).

Results: After applying the selection criteria, 31 studies were included.

Current status and future perspectives of radiomics in hepatocellular carcinoma.

Given the frequent co-existence of an aggressive tumor and underlying chronic liver disease, the management of hepatocellular carcinoma (HCC) patients requires experienced multidisciplinary team discussion. Moreover, imaging plays a key role in the diagnosis, staging, restaging, and surveillance of HCC. Currently, imaging assessment of HCC entails the assessment of qualitative characteristics which are prone to inter-reader variability.

Liver resection for hepatocellular carcinoma beyond the BCLC: are multinodular disease, portal hypertension, and portal system invasion real contraindications?

Background: Barcelona Clinic Liver Cancer (BCLC) is a recognized guideline to standardize treatment allocation for hepatocellular carcinoma (HCC); however, many centers criticize its restrictive liver resection recommendations and have published good results after more liberal hepatectomy indications. The objective is to evaluate the results of HCC resection in a single center, with a more liberal indication for resection than proposed by the BCLC guideline. It was performed a retrospective cohort study including all patients who underwent liver resection for HCC in a single center between April 2008 and November 2018.

Liver resection for hepatolithiasis: A multicenter experience in Latin America.

Background: Hepatolithiasis is a prevalent disease in Asia but rare in Western countries. An increasing number of cases have been reported in Latin America. Liver resection has been proposed as a definitive treatment for complete stone clearance.

Multiple colorectal liver metastases resection can offer long-term survival: The concept of a chronic neoplastic disease.

Background: Resection for colorectal liver metastases has evolved significantly and, currently, there are no limits to the number of resected nodules. This study aimed to evaluate the outcomes and prognostic factors after liver resection for patients with ≥4 colorectal liver metastases, emphasizing long-term survival.

Methods: The study population consisted of 137 patients with ≥4 colorectal liver metastases out of a total of 597 patients with colorectal liver metastases who underwent curative intent liver resection from January 2010 to July 2019 in a single hepatobiliary center.

The impact of multivisceral liver resection on short- and long-term outcomes of patients with colorectal liver metastasis: A systematic review and meta-analysis.

The impact of Multivisceral Liver Resection (MLR) on the outcome of patients with Colorectal Liver Metastasis (CRLM) is unclear. The present systematic review aimed to compare patients with CRLM who underwent MLR versus standard hepatectomy regarding short- and long-term outcomes. MLR is a feasible procedure but has a higher risk of major complications.

Preoperative inflammatory markers as prognostic predictors after hepatocellular carcinoma resection: data from a western referral center.

Background: Recent studies from eastern centers have demonstrate an association between inflammatory response and long-term outcomes after hepatocellular carcinoma (HCC) resection. However, the prognostic impact of inflammatory markers in western patients, with distinct tumor and epidemiologic features, is still unknown.
