Endoportal Radiofrequency Ablation and Stent Placement in Patients with Portal Vein Tumor Thrombosis from Hepatocellular Carcinoma: A Study on Feasibility and Safety.

: Hepatocellular carcinoma (HCC) is the most common type of liver cancer, with 10-40% of cases involving portal vein tumor thrombosis (PVTT), leading to poor outcomes and a short survival. The effectiveness of PVTT treatment in patients with HCC is still controversial. : This prospective dual-center study cohort comprised 60 patients with HCC and PVTT who underwent PVR-EPRFA-ST using a novel intravascular radiofrequency system followed by vascular stent placement across the PVTT stenosed segment under fluoroscopy guidance.

A case of improved quality of life in a patient with inoperable pancreatic cancer after repeated RFA.

Radiofrequency ablation (RFA) has widespread popularity due to its immune-modulation effects in many cancers. Optimal settings to apply RFA in pancreatic cancer, in which the advanced stage of the tumor at the diagnosis makes various therapeutic approaches fail, are still demanding. We report the case of a patient with unresectable pancreatic cancer in which 3 repetitive RFA has been applied over a period of 3 months.

Percutaneous catheter drainage of pancreatic associated pathologies: A systematic review and meta-analysis.

Purpose: The main goal of this systematic review was to assess the technical and clinical success, adverse events (AEs), surgery, and overall mortality proportion after percutaneous catheter drainage (PCD) of two pancreatic lesions.

Methods: An extant search in online databases including Scopus, PubMed (Medline), Embase (Elsevier), Web of Science, Cochrane library, and Google Scholar, was conducted to recognize all studies that used PCD intervention in the management of pancreatic necrosis (PN) and pancreatic pseudocysts (PP). Random effects meta-analysis was performed, and Cochrane's Q test and Istatistic were utilized to determine heterogeneity.

Left gastric artery embolization for obesity treatment: a systematic review and meta-analysis of human and animal studies.

Purpose: The main purpose of this systematic review was to reflect on recent literature on bariatric LGA embolization for obesity treatment and to compare this new procedure in human and animal studies.

Methods: A systematic search of Scopus, MEDLINE, Web of Science, Embase, and Google Scholar was performed to identify human and animal studies employing bariatric LGA embolization to treat obesity. As well, Cochrane's Q test and the I statistic were utilized to determine heterogeneity.

Cured giant hepatocellular carcinoma after transarterial embolization complicated with liver abscess formation.

Many patients with hepatocellular carcinoma cannot be treated surgically because of the advanced stage of the tumor and/or coexisting cirrhosis. Transcatheter arterial embolization (TAE) represents an alternative therapeutic approach for some of these patients. However, it is not a curative measure, and an additional therapy is required to eradicate the residual disease.

Efficacy of percutaneous biliary and pancreatic duct drainage/stenting with double invaginated pancreatojejunostomy after pancreatoduodenectomy.

Aim: To evaluate the efficacy and feasibility of preoperative percutaneous pancreatic duct drainage (PPDD) and improve the safety of pancreatojejunal anastomosis, we refer to our experience from 2013 to 2017 that include the last series of 27 cases of PD for 14 pancreatic and 13 ampullary tumors. Apart from the standard "classic" Whipple procedure in 17 cases, and the "modified"pylorus-preserving variant (ppPD) in 10 cases, in 26 cases a pancreaticojejunostomy and in 1 case a pancreatico gastrostomy was performed. In last series the percutaneous biliary drainage procedure in 18 cases and dual biliary + pancreatic duct decompression in 4 casas was performed.

Immunomodulatory Changes Following Isolated RF Ablation in Colorectal Liver Metastases: A Case Report.

Colorectal cancer (CRC) is the third most common cancer worldwide and the second leading cause of cancer-related deaths in developed countries. The liver is the most prevalent site of metastasis from CRC. Currently, the gold-standard treatment for colorectal liver metastases (CLMs) is surgical resection.

Study to evaluate the immunomodulatory effects of radiofrequency ablation compared to surgical resection for liver cancer.

Hepatic cancer is a highly lethal tumour with increasing worldwide incidence. These tumours are characterized by the proliferation of malignant cells, generalised immunosuppression and chronic inflammation marked with an increase in inflammatory markers as a neutrophil-to-lymphocyte ratio (NLR), the platelet-to-lymphocyte ratio (PLR) and overexpression of CD4+CD39+ on T lymphocytes. The studies have outlined immunomodulatory changes in liver cancer patients as the plausible explanation for the better survival.

Long-term survival in a patient with low-level inflammatory markers and liver metastasis, converted resectable by TACE.

Case report presents the successful treatment of unresectable liver metastasis in a patient with colon cancer. A 44-year-old male underwent right hemicolectomy followed by capecitabine for a moderately differentiated adenocarcinoma of the colon. 2 years later, a liver metastatic lesion was detected and had increased in size despite chemotherapy with capecitabine plus oxaliplatin (XELOX).

Tumor Regression in HCC Patient with Portal Vein Tumor Thrombosis after Intraportal Radiofrequency Thermal Ablation.

Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related death worldwide. Portal vein tumor thrombosis (PVTT) is a frequent entity in HCC, which strictly limits the gold standard treatment options such as surgical resection and transarterial chemoembolization. Therefore, the prognosis of patients with PVTT is extremely poor and an emergence of seeking an alternative option for intervention is inevitable.

Multidetector computed tomography angiography in the management of transarterial embolization of primary and secondary liver malignancy.

Background: Endovascular management is the mainstay of therapy for most patients with primary and secondary liver tumors. Radiologist should understand the anatomy of the hepatic vasculature and tumor feeding vessels to ensure successful conduction of the embolization procedure. The aim of this study was to evaluate the accuracy of multidetector computed tomographic angiography (MDCTA) for the evaluation of hepatic arterial anatomy and tumor feeding vessels prior to embolization procedure.

Novel RNA oligonucleotide improves liver function and inhibits liver carcinogenesis in vivo.

Unlabelled: Hepatocellular carcinoma (HCC) occurs predominantly in patients with liver cirrhosis. Here we show an innovative RNA-based targeted approach to enhance endogenous albumin production while reducing liver tumor burden. We designed short-activating RNAs (saRNA) to enhance expression of C/EBPα (CCAAT/enhancer-binding protein-α), a transcriptional regulator and activator of albumin gene expression.

We report a retrospective study with the results of first in man percutaneous intraductal radiofrequency ablation in patients with malignant biliary obstruction.

Methods: Thirty-nine patients with inoperable malignant biliary obstruction were included.

Novel percutaneous radiofrequency ablation of portal vein tumor thrombus: safety and feasibility.

Purpose: We report our experience of the safety of partial recanalization of the portal vein using a novel endovascular radiofrequency (RF) catheter for portal vein tumor thrombosis.

Towards the optimization of management of hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is the fifth most common neoplasm in the world, closely correlated with viral hepatitis and liver cirrhosis. The vast majority of HCC patients present at a late stage and are unsuitable for surgery due to limited liver functional reserve. Tumors can involve major vessels or hilar structures, necessitating major liver resection and/or rendering liver resection unfeasible.
