Preoperative CT-Scan Angiography Reconstruction Before Right Colectomy with Complete Mesocolon Excision: A Systematic Review and Meta-analysis.

Background: Complete mesocolon excision (CME) and central vascular ligation for right colonic cancers have been developed to improve oncological outcomes. However, it has been linked with a higher risk of morbidity and technical difficulties in operating near major vessels. This study investigated the impact of preoperative surgical planning utilizing CT reconstruction on surgical outcomes in right colectomy with CME.

Hepatocellular Cancer Surveillance in Patients with Advanced Chronic Liver Disease.

Objective: This study assessed the clinical usefulness of shear wave elastography (SWE) during ultrasound for differentiating between focal nodular hyperplasias (FNHs) and hepatocellular adenomas (HAs).

Materials And Methods: SWE was performed on 56 patients presenting with 76 liver lesions (57 FNHs and 19HAs) that were confirmed by MRI and contrast-enhanced ultrasound (CEUS) (n=55) or by histology (n=21). A mean elasticity value was obtained for each lesion.

Treatment of hepatocellular carcinomas by thermal ablation and hepatic transarterial chemoembolization.

Local tumor recurrence after thermal ablation of hepatocellular carcinoma (HCC) can impact on overall survival and are very closely linked to partial treatment of the primary lesion or to potential microvascular invasion or satellite micronodules located close to the main lesion. The diagnosis of these liver metastases close to the primary lesion on CT and MRI is difficult and their incidence, number and spread throughout the liver correlates with diameter of primary tumor. Tumor diameter is currently the key factor to predict whether or not thermal ablation of HCC will be complete or not.

Prognostic factors in patients with refractory ascites treated by transjugular intrahepatic porto-systemic shunt: From the liver to the kidney.

Biomarkers of angiogenesis for the development of antiangiogenic therapies in oncology: tools or decorations?

Since 2004, four antiangiogenic drugs have been approved for clinical use in patients with advanced solid cancers, on the basis of their capacity to improve survival in phase III clinical studies. These achievements validated the concept introduced by Judah Folkman that the inhibition of tumor angiogenesis could control tumor growth. It has been suggested that biomarkers of angiogenesis would greatly facilitate the clinical development of antiangiogenic therapies.
