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.

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).

Identification of a TGF-β/SMAD/lnc-UTGF positive feedback loop and its role in hepatoma metastasis.

Aberrant activation of the TGF-β/SMAD signaling pathway is often observed in hepatocellular carcinoma (HCC). Whether lncRNA regulates the TGF-β/SMAD signaling remains largely unknown. Here, we identified an oncogenic lncRNA that was upregulated in HCC and was transcriptionally induced by TGF-β (named lnc-UTGF, lncRNA upregulated by TGF-β).

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.

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.

Methods: Liver metastases in 249 CRCLM patients were retrospectively analyzed.

Pathologic response after preoperative therapy predicts prognosis of Chinese colorectal cancer patients with liver metastases.

Background: Pathologic response is evaluated according to the extent of tumor regression and is used to estimate the efficacy of preoperative treatment. Several studies have reported the association between the pathologic response and clinical outcomes of colorectal cancer patients with liver metastases who underwent hepatectomy. However, to date, no data from Chinese patients have been reported.

The Role of Adjuvant Chemotherapy for Colorectal Liver Metastasectomy after Pre-Operative Chemotherapy: Is the Treatment Worthwhile?

Peri-operative chemotherapy has been proposed to improve the survival of patients with colorectal cancer hepatic metastases (CRCHM). However, the role of the adjuvant chemotherapy post-metastasectomy for CRCHM patients who have undergone pre-operative chemotherapy is still undetermined. We retrospectively analyzed the role of adjuvant chemotherapy post-metastasectomy on relapse-free survival (RFS) and overall survival (OS) in 163 CRCHM patients who received pre-operative chemotherapy using a Kaplan-Meier curve and univariate/multiple Cox model.

Overexpression of CHD1L is positively associated with metastasis of lung adenocarcinoma and predicts patients poor survival.

CHD1L (chromodomain helicase/ATPase DNA binding protein 1-like gene) has been demonstrated as an oncogene in hepatocellular carcinoma (HCC), however, the role of CHD1L in non-small-cell lung cancer (NSCLC) tumorigenesis hasn't been elucidated. In this study, the expression and amplification status of CHD1L were examined by immunohistochemistry and fluorescence in situ hybridization respectively in 248 surgically resected NSCLCs. The associations between CHD1L expression and clinicopathologic features and the prognostic value of CHD1L were analyzed.

Skp2-dependent ubiquitination and activation of LKB1 is essential for cancer cell survival under energy stress.

LKB1 is activated by forming a heterotrimeric complex with STRAD and MO25. Recent studies suggest that LKB1 has pro-oncogenic functions, besides acting as a tumor suppressor. How the LKB1 activity is maintained and how LKB1 regulates cancer development are largely unclear.

Upregulation of microRNA-106b is associated with poor prognosis in hepatocellular carcinoma.

Background: MicroRNA-106b (miR-106b) is a member of the miR-106b ~ 25 cluster. It has been reported that miR-106b acts as an oncogene and is upregulated in many human cancers. However, the prognostic value of miR-106b in hepatocellular carcinoma (HCC) remains unclear.

Genome-wide mutational signatures of aristolochic acid and its application as a screening tool.

Aristolochic acid (AA), a natural product of Aristolochia plants found in herbal remedies and health supplements, is a group 1 carcinogen that can cause nephrotoxicity and upper urinary tract urothelial cell carcinoma (UTUC). Whole-genome and exome analysis of nine AA-associated UTUCs revealed a strikingly high somatic mutation rate (150 mutations/Mb), exceeding smoking-associated lung cancer (8 mutations/Mb) and ultraviolet radiation-associated melanoma (111 mutations/Mb). The AA-UTUC mutational signature was characterized by A:T to T:A transversions at the sequence motif A[C|T]AGG, located primarily on nontranscribed strands.

Purpose: MicroRNAs (miRNAs) play important roles in the development and progression of cancer. The aim of this study is to identify miRNA expression signatures in hepatocellular carcinoma and delineate their clinical significance for hepatocellular carcinoma.

Experimental Design: Patients with hepatocellular carcinoma, undergoing hepatectomy were randomly divided into training set (60 patients) and test set (50 patients).

Allele loss and down-regulation of heparanase gene are associated with the progression and poor prognosis of hepatocellular carcinoma.

Objectives: The role of heparanase (HPSE) gene in cancers including hepatocellular carcinoma (HCC) is currently controversial. This study was aimed at investigating the impact of genetic alteration and expression change of HPSE on the progression and prognosis of HCC.

Methods: The HPSE gene was studied in three different aspects: (1) loss of heterozygosity (LOH) by a custom SNP microarray and DNA copy number by real-time PCR; (2) mRNA level by qRT-PCR; and (3) protein expression by immunohistochemistry.

Liver hypertrophy and accelerated growth of implanted tumors in nonembolized liver of rabbit after left portal vein embolization.

Background: Portal vein embolization (PVE) has become a standard preoperative procedure to promote hypertrophy of the future remnant liver to reduce postoperative liver failure. Whether PVE accelerates tumor growth is still controversial. We developed a left PVE procedure and investigated its effect on liver hypertrophy and tumor growth in a rabbit liver tumor model.

LIN28 expression and prognostic value in hepatocellular carcinoma patients who meet the Milan criteria and undergo hepatectomy.

Stem cell marker LIN28, related closely with SOX2 and OCT4, has been studied as a biomarker for the maintainance of pluripotent cells in several malignancies. Our previous study showed that SOX2 and OCT4 were negative predictors for hepatocellular carcinoma (HCC). However, the predictive value of LIN28 in HCC outcome is still undetermined.

NADPH oxidase DUOX1 and DUOX2 but not NOX4 are independent predictors in hepatocellular carcinoma after hepatectomy.

NADPH oxidase DUOX1, DUOX2, and NOX4 have recently been gained considerable concerns, owing to the fact that they involve in reactive oxygen species-induced genetic and epigenetic alternations of human carcinogenesis and serve as biomarkers in several cancers. Whether they predict survival in hepatocellular carcinoma (HCC) is still uncertain. Here, we detected the expressions of DUOX1, DUOX2, and NOX4 in one normal liver cell line, seven HCC cell lines, 30 non-cirrhotic normal liver tissues, and 107 paired HCC tissues using reverse transcription-polymerase chain reaction.
