Expert consensus on sequential surgery following conversion therapy based on combination of immune checkpoint inhibitors and antiangiogenic targeted drugs for advanced hepatocellular carcinoma (2024 edition).

Up to half of hepatocellular carcinoma (HCC) cases are diagnosed at an advanced stage, for which effective treatment options are lacking, resulting in a poor prognosis. Over the past few years, the combination of immune checkpoint inhibitors and anti-angiogenic targeted therapy has proven highly efficacious in treating advanced HCC, significantly extending patients' survival and providing a potential for sequential curative surgery. After sequential curative hepatectomy or liver transplantation following conversion therapy, patients can receive long-term survival benefits.

Lenvatinib plus anti-PD-1 antibodies as conversion therapy for patients with unresectable intermediate-advanced hepatocellular carcinoma: a single-arm, phase II trial.

Background: Over 70% of the patients with hepatocellular carcinoma (HCC) are diagnosed at an advanced stage and lose the opportunity for radical surgery. Combination therapy of tyrosine kinase inhibitors (TKIs) and anti-programmed cell death protein-1 (PD-1) antibodies has achieved a high tumor response rate in both the first-line and second-line treatment of advanced HCC. However, few studies have prospectively evaluated whether TKIs plus anti-PD-1 antibodies could convert unresectable intermediate-advanced HCC into resectable disease.

Effect of Huaier granule on recurrence after curative resection of HCC: a multicentre, randomised clinical trial.

Objective: There is little evidence that adjuvant therapy after radical surgical resection of hepatocellular carcinoma (HCC) improves recurrence-free survival (RFS) or overall survival (OS). We conducted a multicentre, randomised, controlled, phase IV trial evaluating the benefit of an aqueous extract of Murr (Huaier granule) to address this unmet need.

Design And Results: A total of 1044 patients were randomised in 2:1 ratio to receive either Huaier or no further treatment (controls) for a maximum of 96 weeks.

Perioperative and long-term outcomes of liver resection for hepatitis B virus-related hepatocellular carcinoma without versus with hepatic inflow occlusion: study protocol for a prospective randomized controlled trial.

Background: The high prevalence of hepatitis B virus (HBV) imposes a huge burden of hepatocellular carcinoma (HCC) in Asia. Surgical resection remains an important therapeutic strategy for HCC. Hepatic inflow occlusion, known as the Pringle maneuver, is the most commonly used method of reducing blood loss during liver parenchymal transection.

Loss of GATA5 expression due to gene promoter methylation induces growth and colony formation of hepatocellular carcinoma cells.

GATA5 is a transcription factor that is capable of suppressing the development of various types of human cancer. The present study investigated the expression of GATA5 and GATA4, and examined their roles in the proliferation and colony formation ability of hepatocellular carcinoma (HCC) tissues and cells. The GATA4 and GATA5 expression levels and gene promoter methylation of HCC tissue samples from 38 patients and HCC cell lines were analyzed using reverse transcription-polymerase chain reaction (RT-PCR) and methylation-specific PCR (MSP), respectively.

Ultrasound-guided radiofrequency ablation of the segmental Glissonian pedicle: A new technique for anatomic liver resection.

Background: Anatomic liver resection is widely accepted as the optimal surgical treatment for hepatocellular carcinoma (HCC); however, the complexity of conventional operative methods limits their use. To explore the possibility of using modern techniques to achieve a simpler approach, we have evaluated ultrasound-guided segmental radiofrequency ablation (RFA) of the Glissonian pedicle before liver resection in a porcine model and in HCC patients.

Methods: This study had 2 stages.

A New Segmental Hepatectomy Approach Using Ultrasound-Guided Portal Branch Infusion of a Thermosensitive Gel in Pigs.

Background: The aim of this study was to evaluate the safety, feasibility, and efficacy of a new segmental hepatectomy (SH) approach using intraoperative ultrasound (IOUS) guided infusion of a reversible thermosensitive gel into the portal vein branch in pigs;

Materials And Methods: Poloxamer 407 aqueous solution (20%, W/V) was mixed with indocyanine green (P407-ICG) in this study to make it green, and it remained liquid at room temperature and turned into a firm gel upon reaching body temperature. In experiment I, six pigs were used to detect the outcome of infusing the mixture into the biliary tract, liver parenchyma, and hepatic vein for a safety study. In experiment II, another 12 pigs were randomly segmented into two groups [SH group and partial hepatectomy (PH) group] to investigate the feasibility and efficacy of the new approach using IOUS-guided infusion of the mixture into the portal branch;

Results: No thermosensitive gel-induced abnormal changes were observed in the safety study.

MicroRNA‑506 participates in pancreatic cancer pathogenesis by targeting PIM3.

MicroRNA (miRNA) is a type of short non-coding RNA that suppresses the expression of protein coding genes by partial complementary binding to the 3'‑untranslated regions (UTRs) of mRNAs. miRNA expression alterations are involved in the initiation, progression and metastasis of human cancer and it has been suggested that miRNAs function as tumor suppressors as well as oncogenes in cancer development. PIM-3 is a member of the proto-oncogene PIM family, the aberrant expression of which exists in human pancreatic cancer tissues.

Increased expression of pleiotrophin is a prognostic marker for patients with gastric cancer.

Unlabelled: BACKGROUND/AIMs: Pleiotrophin (PTN) have been demonstrated to play an important role in the development of human gastric cancer. However, the prognostic value remains unclear. The aim of this study was to investigate whether expression of PTN has prognostic relevance in human gastric cancer.

Double stranded RNA-dependent protein kinase promotes the tumorigenic phenotype in HepG2 hepatocellular carcinoma cells by activating STAT3.

Previously known as a first-response protein upon viral infection and other stress signals, double-stranded RNA-dependent protein kinase (PKR, also termed EIF2AK2) has been found to be differentially expressed in multiple types of tumor, including hepatocellular carcinoma, suggesting that PKR may be involved in tumor initiation and development. However, whether and how PKR promotes or suppresses the development of hepatocellular carcinoma remains controversial. In the present study, PKR expression was investigated using qPCR and western blot analysis, which revealed that PKR expression was upregulated in liver tumor tissues, when compared to that of adjacent normal tissues, which were obtained from four primary liver cancer patients.
