Gastrointestinal side effects in hepatocellular carcinoma patients receiving transarterial chemoembolization: a meta-analysis of 81 studies and 9495 patients

Background

Transarterial chemoembolization (TACE) is a widely used treatment for hepatocellular carcinoma (HCC), combining targeted chemotherapy and embolization. While effective, TACE can be associated with significant gastrointestinal (GI) side effects, impacting a patient's quality of life.

Objectives

Quantify the prevalence of key GI complications (diarrhea, nausea, GI toxicity, abdominal pain) following TACE.

Design

Systematic review was performed following Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines, focusing on studies that reported side effects of TACE. Studies not involving cTACE or drug-eluting bead TACE (DEB-TACE), non-HCC studies, meta-analyses or systematic reviews, and inaccessible publications were excluded.

Data sources and methods

A PubMed search for clinical and randomized trials was conducted. Extracted data included study identifiers, demographics, TACE details, and GI side effect prevalences. The Mixed Methods Appraisal Tool assessed study quality and bias.

Results

The analysis included data from 81 studies with 121 individual study arms and 9495 patients. Diarrhea was reported in 38 studies, with a mean prevalence of 23.46% (2.5; 95% confidence interval (CI): 18.39-28.544) and a weighted prevalence of 23.5%. Nausea was most frequently reported, mentioned in 67 studies, with a mean prevalence of 34.66% (2.4; 95% CI: 29.89-39.44) and a weighted prevalence of 32.5%. Abdominal pain was reported in 59 studies, with the highest mean prevalence of 48.07% (2.9; 95% CI: 42.20-53.93) and a weighted prevalence of 46.1%. GI toxicity was reported in 32 studies, with a mean prevalence of 8.85% (1.4; 95% CI: 5.99-11.70) and a weighted prevalence of 9.9%. DEB-TACE generally led to slightly higher rates of nausea, diarrhea, abdominal pain, and GI toxicity compared to conventional TACE. The type of chemotherapy agent influenced prevalence of GI-side effects, with high prevalences observed for agents such as zinostatin and cisplatin.

Conclusion

This meta-analysis synthesizes current evidence on managing GI side effects in TACE. Standardizing reporting and developing effective management strategies are crucial to improving patient outcomes.

Biomarkers for diagnosis and therapeutic options in hepatocellular carcinoma

Liver cancer is a global health challenge, causing a significant social-economic burden. Hepatocellular carcinoma (HCC) is the predominant type of primary liver cancer, which is highly heterogeneous in terms of molecular and cellular signatures. Early-stage or small tumors are typically treated with surgery or ablation. Currently, chemotherapies and immunotherapies are the best treatments for unresectable tumors or advanced HCC. However, drug response and acquired resistance are not predictable with the existing systematic guidelines regarding mutation patterns and molecular biomarkers, resulting in sub-optimal treatment outcomes for many patients with atypical molecular profiles. With advanced technological platforms, valuable information such as tumor genetic alterations, epigenetic data, and tumor microenvironments can be obtained from liquid biopsy. The inter- and intra-tumoral heterogeneity of HCC are illustrated, and these collective data provide solid evidence in the decision-making process of treatment regimens. This article reviews the current understanding of HCC detection methods and aims to update the development of HCC surveillance using liquid biopsy. Recent critical findings on the molecular basis, epigenetic profiles, circulating tumor cells, circulating DNAs, and omics studies are elaborated for HCC diagnosis. Besides, biomarkers related to the choice of therapeutic options are discussed. Some notable recent clinical trials working on targeted therapies are also highlighted. Insights are provided to translate the knowledge into potential biomarkers for detection and diagnosis, prognosis, treatment response, and drug resistance indicators in clinical practice.

An SNP Marker Predicts Colorectal Cancer Outcomes with 5-Fluorouracil-Based Adjuvant Chemotherapy Post-Resection

Colorectal cancer (CRC) is a global health concern, necessitating adjuvant chemotherapy post-curative surgery to mitigate recurrence and enhance survival, particularly in intermediate-stage patients. However, existing therapeutic disparities highlight the need for biomarker-guided adjuvant chemotherapy to achieve better CRC inhibition. This study explores the molecular mechanisms underlying the inhibition of CRC through a genome-wide association study (GWAS) focused on 5-fluorouracil (5-FU)-based adjuvant therapy in intermediate-stage CRC patients, a domain previously unexplored. We retrospectively included 226 intermediate-stage CRC patients undergoing surgical resection followed by 5-FU-based adjuvant chemotherapy. The exploration cohort comprised 31 patients, and the validation cohort included 195 individuals. Genotyping was carried out using either Axiom Genome-Wide TWB 2.0 Array Plate-based or polymerase chain reaction-based methods on genomic DNA derived from collected tissue samples. Statistical analyses involved descriptive statistics, Kaplan-Meier analyses, and Cox proportional hazard analyses. From the GWAS, potential genetic predictors, GALNT14-rs62139523 and DNMBP-rs10786578 genotypes, of 5-FU-based adjuvant therapy following surgery in intermediate-stage CRC patients were identified. Validation in a larger cohort of 195 patients emphasized the predictive significance of GALNT14-rs62139523 genotypes, especially the "A/G" genotype, for improved overall and progression-free survival. This predictive association remained robust across various subgroups, with exceptions for specific demographic and clinical parameters such as age < 58 years old, CEA ≤ 2.5 ng/mL, tumor diameter > 44.0 mm, and tumor-free margin ≥ 50 mm. This study identifies that the GALNT14-rs62139523 "A/G" genotype modulates therapeutic outcomes, establishing it as a promising biomarker for predicting favorable responses to 5-FU-based adjuvant chemotherapy in intermediate-stage CRC patients, although further investigations are needed to detail these mechanisms.

Global trends of targeted therapy for hepatocellular carcinoma: A bibliometric and visualized study from 2008 to 2022

BACKGROUND

Hepatocellular carcinoma (HCC) is an exceedingly prevalent malignancy with an exceptionally poor prognosis. Targeted therapy is an effective treatment option for patients with advanced HCC. However, there have been no bibliometric analyses of targeted therapies for HCC.

METHODS

This study aimed to assess the current status and future directions of targeted therapy for HCC to provide future scholars with clearer research contents and popular themes. Methods: Literature on targeted therapy for HCC from 2008 to 2022 was obtained from the Web of Science (WoS) and assessed using bibliometric methodology. Additionally, the VOS viewer was applied in the visualization study to conduct bibliographic coupling, co-authorship, co-citation, and co-occurrence analyses of publications.

RESULTS

A total of 10,779 papers were subsequently selected. Over the past 15 years, there has been a progressive increase in the number of publications on an annualized basis. China released the most publications in the field, whereas the United States had the highest H-index. Cancers published the most papers. Fudan University had the greatest sway in this area. Studies could be divided into 5 clusters: "Gene and expression research," "Mechanism study," "Nanoparticle study," "Targeted drug research," and "Clinical study."

CONCLUSIONS

In the upcoming years, more papers on targeted therapy for HCC are expected to be released, demonstrating the potential for this topic to flourish. Particularly, "Clinical study" is the following trendy topic in this field. Other research subfields may likewise exhibit a continuous tendency towards balanced development.

Efficacy of transarterial therapy combined with first-line tyrosine kinase inhibitors for unresectable hepatocellular carcinoma: a network meta-analysis

BACKGROUND

Transarterial therapies, including transarterial chemoembolization (TACE), hepatic arterial infusion chemotherapy (HAIC), and selective internal radiation therapy, combined with first-line tyrosine kinase inhibitors (TKIs) are considered the standard therapy for unresectable hepatocellular carcinoma. However, inconsistent results have been reported in various studies assessing different combinations of targeted agents.

METHODS

A network meta-analysis (NMA) was performed by including 23 randomized controlled trials (RCTs) with 6175 patients to investigate the efficiency of transarterial therapies in combination with different TKIs. Outcomes of interest included overall survival (OS), progression-free survival (PFS), time to progression (TTP), and tumor objective response rate (ORR). A random-effects consistency model was used in this Bayesian NMA. Hazard ratio and odd risks with a 95% credible interval were calculated and agents were ranked based on ranking probability.

RESULTS

HAIC showed maximal OS and TTP and TACE plus lenvatinib showed maximal PFS, ORR, and disease control rate (DCR). HAIC and TACE plus lenvatinib were ranked highest based on their respective parameters, which were OS for HAIC and PFS, ORR, and DCR for TACE plus lenvatinib.

CONCLUSION

HAIC and TACE plus lenvatinib were relatively better choice for unresectable hepatocellular carcinoma. However, owing to the lack of statistically significant OS benefits among most agents, other agents should be considered as potential alternatives for unresectable hepatocellular carcinoma.

Recent Advances in Locoregional Therapy of Hepatocellular Carcinoma

Hepatocellular carcinoma (HCC) is responsible for 90% of primary hepatic cancer cases, and its incidence with associated morbidity and mortality is growing worldwide. In recent decades, there has been a revolution in HCC treatment. There are three main types of locoregional therapy: radiofrequency ablation, transarterial chemoembolisation, and transarterial radioembolisation. This article summarises recent advances in locoregional methods.

Transarterial chemoembolization with or without multikinase inhibitors for patients with unresectable hepatocellular carcinoma: a systematic review and meta-analysis of randomized controlled trials

Background

Randomized controlled trials (RCTs) testing the combination therapy of transarterial chemoembolization (TACE) plus multikinase inhibitor (MKI) in patients with unresectable hepatocellular carcinoma (HCC) have yielded inconsistent results.

Methods

In this work, a systematic review and meta-analysis was performed to compare the TACE+MKI combination therapy versus TACE monotherapy in HCC patients with time to progression (TTP) adopted as primary outcome.

Results

A total of 10 RCTs comprising 2837 patients receiving combination therapy (TACE plus sorafenib, brivanib, orantinib or apatinib) were included. TACE+MKI significantly prolonged TTP (hazard ratio [HR] 0.74, 95% CI 0.62-0.89, p=0.001) versus TACE monotherapy. Subgroup analysis suggested MKI administration before TACE might be preferable to post-TACE MKI for TTP. TACE+MKI also increased objective response rate (ORR) (risk ratio [RR] 1.17, 95% CI 1.03-1.32, p=0.01), but failed to improve overall survival (OS) (HR 0.98, 95% CI 0.86-1.13, p=0.82) and progression-free survival (PFS) (HR 0.75, 95% CI 0.50-1.12, p=0.16). The incidence of any adverse event (AE) did not significantly differ between TACE+MKI and TACE groups (RR 1.17, 95% CI 0.96-1.42, p=0.01), while serious AEs showed significant difference (RR 1.41, 95% CI 1.26-1.59, p<0.0001). Nevertheless, these AEs showing significant difference were mainly associated with MKI toxicities rather than TACE.

Conclusions

TACE+MKI combination therapy improved TTP and ORR but not OS and PFS in patients with unresectable HCC. Further high-quality trials are needed to verify these clinical benefits, and our findings could be very informative for future trial design.

Immune-related gene signature to predict TACE refractoriness in patients with hepatocellular carcinoma based on artificial neural network

Background: Transarterial chemoembolization (TACE) is the standard treatment option for intermediate-stage hepatocellular carcinoma (HCC), while response varies among patients. This study aimed to identify novel immune-related genes (IRGs) and establish a prediction model for TACE refractoriness in HCC patients based on machine learning methods. Methods: Gene expression data were downloaded from GSE104580 dataset of Gene Expression Omnibus (GEO) database, differential analysis was first performed to screen differentially expressed genes (DEGs). The least absolute shrinkage and selection operator (LASSO) regression analysis was performed to further select significant DEGs. Weighted gene co-expression network analysis (WGCNA) was utilized to build a gene co-expression network and filter the hub genes. Final signature genes were determined by the intersection of LASSO analysis results, WGCNA results and IRGs list. Based on the above results, the artificial neural network (ANN) model was constructed in the training cohort and verified in the validation cohort. Receiver operating characteristics (ROC) analysis was used to assess the prediction accuracy. Correlation of signature genes with tumor microenvironment scores, immune cells and immune checkpoint molecules were further analyzed. The tumor immune dysfunction and exclusion (TIDE) score was used to evaluate the response to immunotherapy. Results: One hundred and forty-seven samples were included in this study, which was randomly divided into the training cohort (n = 103) and validation cohort (n = 44). In total, 224 genes were identified as DEGs. Further LASSO regression analysis screened out 25 genes from all DEGs. Through the intersection of LASSO results, WGCNA results and IRGs list, S100A9, TREM1, COLEC12, and IFIT1 were integrated to construct the ANN model. The areas under the curves (AUCs) of the model were .887 in training cohort and .765 in validation cohort. The four IRGs also correlated with tumor microenvironment scores, infiltrated immune cells and immune checkpoint genes in various degrees. Patients with TACE-Response, lower expression of COLEC12, S100A9, TREM1 and higher expression of IFIT1 had better response to immunotherapy. Conclusion: This study constructed and validated an IRG signature to predict the refractoriness to TACE in patients with HCC, which may have the potential to provide insights into the TACE refractoriness in HCC and become the immunotherapeutic targets for HCC patients with TACE refractoriness.

Association of rs9679162 Genetic Polymorphism and Aberrant Expression of Polypeptide N-Acetylgalactosaminyltransferase 14 (GALNT14) in Head and Neck Cancer

Simple Summary

Neoadjuvant chemotherapy was performed before surgery. Because the tumor itself and the surrounding vascular bed were not damaged, the chemotherapy we performed could have good drug delivery. After the operation, the volume of the tumor can be reduced to facilitate surgery or radiotherapy. However, neoadjuvant chemotherapy also delays the patient’s time to receive main therapy. The physician must make sure that it has a good response and does not allow disease progression in the patient during neoadjuvant chemotherapy. Therefore, predicting the treatment response of neoadjuvant chemotherapy can shorten the treatment time, reduce the harm of chemotherapy side effects, and avoid the occurrence of drug resistance. The results of this study showed that GALNT14-rs9679162 and mRNA expression were associated with post-treatment survival in head and neck cancer. It can be used as an indicator to predict the treatment response of neoadjuvant chemotherapy.

Abstract

The polypeptide N-Acetylgalactosaminyltransferase 14 (GALNT14) rs9679162 and mRNA expression were associated with treatment outcome in various cancers. However, the relation of GALNT14 and head and neck cancer were nuclear. A total of 199 patients with head and neck squamous cell carcinoma (HNSCC) were collected in this study, including oral SCC (OSCC), oropharyngeal SCC (OPSCC), laryngeal SCC (LSCC), and others. The DNA and RNA of cancer tissues were extracted using the TRI Reagent method. The rs9679162 was analyzed using polymerase chain reaction (PCR) and sequencing methods in 199 DNA specimens, and the mRNA expression was analyzed using quantitative reverse transcription PCR (RT-qPCR) methods in 68 paired RNA specimens of non-cancerous matched tissues (NCMT) and tumor tissues. The results showed that the genotype of TT, TG, and GG appeared at 30%, 44%, and 26%, respectively. Non-TT genotype or G alleotype were associated with alcohol, betel nut, and cigarette using among patients with OSCC, and it also affected the treatment and survival of patients with OSCC and LSCC. High GALNT14 mRNA expression levels increased lymphatic metastasis of patients with HNSCC, and treatment and survival in patients with OPSCC. Overall, the GALNT14-rs9679162 genotype and mRNA expression level can be used as indicators of HNSCC treatment prognosis.
