Percutaneous hepatic artery infusion chemotherapy with oxaliplatin and fluoropyrimidines in treatment-resistant colorectal cancer patients with unresectable liver metastases: a retrospective cohort study.

Background: Subsequent lines of therapy for chemotherapy-resistant metastatic colorectal cancer (CRC) have shown limited efficacy. Herein, we retrospectively investigated the efficacy and safety of hepatic artery infusion chemotherapy (HAIC) using oxaliplatin plus 5-FU/FUDR in patients with unresectable colorectal liver metastases (CRLM) who progressed following standard chemotherapy regimens.

Methods: From March 2017 to April 2023, CRC patients with unresectable CRLM who progressed following standard chemotherapy and subsequently received HAIC oxaliplatin plus 5-FU/FUDR were evaluated.

Safety and efficacy of adjuvant FOLFOX/FOLFIRI with versus without hepatic arterial infusion of floxuridine in patients following colorectal cancer liver metastasectomy (HARVEST trial): A randomized controlled trial.

Background: Hepatic artery infusion (HAI) chemotherapy, particularly with floxuridine (FUDR), has previously shown effectiveness in improving recurrence-free survival (RFS) in colorectal cancer (CRC) patients with colorectal liver metastases (CRLM). Nonetheless, its adjuvant use alongside modern systemic chemotherapy remains unevaluated.

Patients And Methods: The HARVEST trial is an open-label, randomized, controlled study conducted from May 2018 to August 2021.

TSPO is a novel biomarker for prognosis that regulates cell proliferation through influencing mitochondrial functions in HCC.

The disorder of mitochondrial functions plays a key role in oncogenesis. It is known that TSPO (18-kDa translocator protein) lies in a peculiar location at the interface between the mitochondria and the cytosol. TSPO is found in many types of tissues and is associated with multiple cellular processes, including apoptosis, cell proliferation and the regulation of mitochondria.

A detailed assessment of liver function in patients with hepatocellular carcinoma via the modified albumin-bilirubin (mALBI) grade.

Recently, the albumin-bilirubin (ALBI) score, a continuous index consisting of only albumin and bilirubin, has been developed for objectively assessing liver function in patients with hepatocellular carcinoma (HCC). However, the ALBI score was arbitrarily categorized into three ALBI grades based on two artificially predetermined cutoff points with no explanation and statistical grounds, causing a considerable loss of discriminatory ability. This study aims to propose a modified ALBI (mALBI) grade for offering a detailed evaluation of hepatic reserve and specify its role during clinical practice in the HCC setting.

More Liver Metastases Detected Intraoperatively Indicates Worse Prognosis for Colorectal Liver Metastases Patients after Resection Combined with Microwave Ablation.

Background: Whether more tumor numbers detected in surgery compared to preoperative image affecting survival of colorectal liver metastases (CRLM) patients after hepatectomy combined with microwave ablation (MWA) remains unclear.

Methods: From 2013 to 2018, 85 CRLM patients who underwent hepatectomy combined with MWA were retrospectively assessed. Compared to the tumor numbers in preoperative image, patients with equal intraoperative tumor numbers were defined as the equal number group ( = 45); patients detected more tumor numbers in surgery were defined as the more number group ( = 40).

Influence of AFP on surgical outcomes in non-B non-C patients with curative resection for hepatocellular carcinoma.

To study the clinical and prognostic features of non-B non-C alpha-fetoprotein (AFP)(-)-hepatocellular carcinoma (HCC) (NBNC-AFP(-)-HCC) and the relationship between the prognostic features of HCC and hepatitis B virus surface antigen (HBsAg) status and AFP. We enrolled 227 patients who underwent hepatic resection for HCC between January 1998 and December 2007 at Sun Yat-sen University Cancer Center, all of whom were diagnosed with HCC by pathology. All patients were stratified into one of four groups (B-AFP(+)-HCC, B-AFP(-)-HCC, NBNC-AFP(+)-HCC, and NBNC-AFP(-)-HCC) according to AFP levels and HBsAg status.

Dynamic monitoring of circulating tumor DNA to predict prognosis and efficacy of adjuvant chemotherapy after resection of colorectal liver metastases.

Hepatectomy and adjuvant chemotherapy after resection of colorectal liver metastases (CRLM) may improve survival, however, patients which may benefit cannot currently be identified. Postoperative circulating tumor DNA (ctDNA) analysis can detect minimal residual disease (MRD) and predict the prognosis and efficacy of adjuvant chemotherapy. Our study aims to determine the impact of serial ctDNA analysis to predict the outcome among patients undergoing resection of CRLM.

LncRNA Lnc-APUE is Repressed by HNF4 and Promotes G1/S Phase Transition and Tumor Growth by Regulating MiR-20b/E2F1 Axis.

Many long noncoding RNAs (lncRNAs) have been annotated, but their functions remain unknown. The authors found a novel lnc-APUE (lncRNA accelerating proliferation by upregulating E2F1) that is upregulated in different cancer types, including hepatocellular carcinoma (HCC), and high lnc-APUE level is associated with short recurrence-free survival (RFS) of HCC patients. Gain- and loss-of-function analyses showed that lnc-APUE accelerated G1/S transition and tumor cell growth in vitro and allows hepatoma xenografts to grow faster in vivo.

RALYL increases hepatocellular carcinoma stemness by sustaining the mRNA stability of TGF-β2.

Growing evidences suggest that cancer stem cells exhibit many molecular characteristics and phenotypes similar to their ancestral progenitor cells. In the present study, human embryonic stem cells are induced to differentiate into hepatocytes along hepatic lineages to mimic liver development in vitro. A liver progenitor specific gene, RALY RNA binding protein like (RALYL), is identified.

Primary tumor immune score fails to predict the prognosis of colorectal cancer liver metastases after hepatectomy in Chinese populations.

Background: Increasing evidence suggests that the immune score is significantly associated with cancer prognosis. However, the prognostic role of primary tumor immune score in colorectal cancer liver metastases (CRLM) after hepatectomy in Chinese patients has not been reported. The present study is designed to investigate whether the immune score of primary tumor can predict the postoperative survival of liver metastases in Chinese patients.

A novel prognostic nomogram for colorectal cancer liver metastasis patients with recurrence after hepatectomy.

Purpose: We aimed to construct a nomogram to predict personalized post-recurrence survival (PRS) among colorectal cancer liver metastasis (CRLM) patients with post-hepatectomy recurrence.

Methods: Colorectal cancer liver metastasis patients who received initial hepatectomy and had subsequent recurrence between 2001 and 2019 in Sun Yat-sen University Cancer Center from China were included in the study. Patients were randomly assigned to a training cohort and a validation cohort on a ratio of 2:1.

PGC7 promotes tumor oncogenic dedifferentiation through remodeling DNA methylation pattern for key developmental transcription factors.

Poorly differentiated tumors usually exhibit phenotypes similar to that of their developmental precursor cells. Tumor cells that acquire the lineage progenitor cells feature usually exploit developmental signaling to potentiate cancer progression. However, the underlying molecular events remain elusive.

PARP inhibitor Olaparib overcomes Sorafenib resistance through reshaping the pluripotent transcriptome in hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is one of the most common human malignancies worldwide with very poor prognosis. Resistance to targeted therapeutic drugs such as sorafenib remains one of the major challenges in clinical treatment. In the present study, PARP1 was found to be highly expressed in human embryonic stem cells, but progressively decreased upon specified hepatic differentiation.

A p53/lnc-Ip53 Negative Feedback Loop Regulates Tumor Growth and Chemoresistance.

Acetylation is a critical mechanism to modulate tumor-suppressive activity of p53, but the causative roles of long non-coding RNAs (lncRNAs) in p53 acetylation and their biological significance remain unexplored. Here, lncRNA LOC100294145 is discovered to be transactivated by p53 and is thus designated as lnc-Ip53 for lncRNA induced by p53. Furthermore, lnc-Ip53 impedes p53 acetylation by interacting with histone deacetylase 1 (HDAC1) and E1A binding protein p300 (p300) to prevent HDAC1 degradation and attenuate p300 activity, resulting in abrogation of p53 activity and subsequent cell proliferation and apoptosis resistance.

PIM2 promotes hepatocellular carcinoma tumorigenesis and progression through activating NF-κB signaling pathway.

Inflammatory factors and activation of oncogenes both played critical roles in the development and progression of human hepatocellular carcinoma (HCC). However, the interplay between these two has not been well studied. In this study, we found that regulated by TNFα, Pim-2 proto-oncogene, serine/threonine kinase (PIM2) was highly expressed in HCC and correlated with poor prognosis (P = 0.

Histopathological growth patterns correlate with the immunoscore in colorectal cancer liver metastasis patients after hepatectomy.

Various scoring systems have been proposed to predict the postoperative prognosis of colorectal liver metastasis (CRLM), including the clinical risk score (CRS), the immunoscore and so on. Recently, histopathological growth patterns (HGPs) have been recognized. However, the correlation between HGPs and the immunoscore, and their prognostic values in patients with CRLM after liver resection remain undetermined.

A hepatocyte differentiation model reveals two subtypes of liver cancer with different oncofetal properties and therapeutic targets.

Clinical observation of the association between cancer aggressiveness and embryonic development stage implies the importance of developmental signals in cancer initiation and therapeutic resistance. However, the dynamic gene expression during organogenesis and the master oncofetal drivers are still unclear, which impeded the efficient elimination of poor prognostic tumors, including human hepatocellular carcinoma (HCC). In this study, human embryonic stem cells were induced to differentiate into adult hepatocytes along hepatic lineages to mimic liver development in vitro.

LINC01554-Mediated Glucose Metabolism Reprogramming Suppresses Tumorigenicity in Hepatocellular Carcinoma via Downregulating PKM2 Expression and Inhibiting Akt/mTOR Signaling Pathway.

Cancer cells prefer aerobic glycolysis to maintain growth advantages, but the role of long non-coding RNAs (lncRNAs) in glycometabolism still remains unclear. Here we identified one cytoplasmic lncRNA LINC01554 as a significantly downregulated lncRNA in hepatocellular carcinoma (HCC) and aimed to investigate its role in cellular glucose metabolism in the development and progression of HCC. Quantitative real-time PCR was used to determine the expression level of LINC01554.

Lymphoid enhancer-binding factor-1 promotes stemness and poor differentiation of hepatocellular carcinoma by directly activating the NOTCH pathway.

The poorly differentiated hepatocellular carcinoma (HCC) cells are usually characterized by immature hepatic progenitor cell-like properties, such as enhanced self-renewal ability, resistance to chemotherapeutic drugs, and a loss of mature hepatocyte proteins. However, the molecular mechanisms governing this process still remain unclear. In this study, we found the lymphoid enhancer-binding factor-1 (LEF1), a transcriptional factor, was frequently overexpressed in HCCs, which was significantly associated with poor prognosis and tumor cell differentiation.

Triterpenoids with α-glucosidase inhibitory activity and cytotoxic activity from the leaves of .

Ten pentacyclic triterpenoids including a new multiflorane triterpene acid, 2α,3β,23-trihydroxymultiflor-7-en-28-oic acid (1), and a new lupane triterpene monoglucoside named akebiaoside C (2), were obtained from the leaves of . Their structures were elucidated by extensive spectroscopic analysis, and they were all isolated from the leaves of for the first time. These compounds, except 4 and 5, showed α-glucosidase inhibitory activity much stronger than acarbose.

Down-regulation of Predicts Poor Prognosis of Hepatocellular Carcinoma Patients.

Hepatocellular carcinoma (HCC) is one of the most common and lethal cancer types worldwide, especially in Asian countries. Genetic alterations, including hyperactivation of oncogenes and loss of expression of tumor suppressor genes, greatly contribute to the initiation and progression of HCC. Here we report that down-regulation of trophoblast cell surface antigen 2 () was frequently detected in HCC.

The efficacy and safety of long- versus short-interval transarterial chemoembolization in unresectable hepatocellular carcinoma.

To compare the efficacy and safety of long- versus short-interval of transarterial chemoembolization (TACE) in unresectable hepatocellular carcinoma (HCC) patients. This retrospective analysis enrolled 574 patients with unresectable HCC who underwent at least two sessions of TACE between January 2007 and December 2014. The patients were divided into a short-interval group (SIG) and a long-interval group (LIG) based on the median TACE interval of the first two sessions.
