Multidisciplinary approach for hepatocellular carcinoma patients: current evidence and future perspectives.

Management of hepatocellular carcinoma (HCC) is challenging due to the complex relationship between underlying liver disease, tumor burden, and liver function. HCC is also notorious for its high recurrence rate even after curative treatment for early-stage tumor. Liver transplantation can substantially alter patient prognosis, but donor availability varies by each patient which further complicates treatment decision. Recent advancements in HCC treatments have introduced numerous potentially efficacious treatment modalities. However, high level evidence comparing the risks and benefits of these options is limited. In this complex situation, multidisciplinary approach or multidisciplinary team care has been suggested as a valuable strategy to help cope with escalating complexity in HCC management. Multidisciplinary approach involves collaboration among medical and health care professionals from various academic disciplines to provide comprehensive care. Although evidence suggests that multidisciplinary care can enhance outcomes of HCC patients, robust data from randomized controlled trials are currently lacking. Moreover, the implementation of a multidisciplinary approach necessitates increased medical resources compared to conventional cancer care. This review summarizes the current evidence on the role of multidisciplinary approach in HCC management and explores potential future directions.

Prognostic MRI features to predict postresection survivals for very early to intermediate stage hepatocellular carcinoma.

OBJECTIVES: Contrast-enhanced MRI can provide individualized prognostic information for hepatocellular carcinoma (HCC). We aimed to investigate the value of MRI features to predict early (≤ 2 years)/late (> 2 years) recurrence-free survival (E-RFS and L-RFS, respectively) and overall survival (OS). MATERIALS AND METHODS: Consecutive adult patients at a tertiary academic center who received curative-intent liver resection for very early to intermediate stage HCC and underwent preoperative contrast-enhanced MRI were retrospectively enrolled from March 2011 to April 2021. Three masked radiologists independently assessed 54 MRI features. Uni- and multivariable Cox regression analyses were conducted to investigate the associations of imaging features with E-RFS, L-RFS, and OS. RESULTS: This study included 600 patients (median age, 53 years; 526 men). During a median follow-up of 55.3 months, 51% of patients experienced recurrence (early recurrence: 66%; late recurrence: 34%), and 17% died. Tumor size, multiple tumors, rim arterial phase hyperenhancement, iron sparing in solid mass, tumor growth pattern, and gastroesophageal varices were associated with E-RFS and OS (largest p = .02). Nonperipheral washout (p = .006), markedly low apparent diffusion coefficient value (p = .02), intratumoral arteries (p = .01), and width of the main portal vein (p = .03) were associated with E-RFS but not with L-RFS or OS, while the VICT2 trait was specifically associated with OS (p = .02). Multiple tumors (p = .048) and radiologically-evident cirrhosis (p < .001) were the only predictors for L-RFS. CONCLUSION: Twelve visually-assessed MRI features predicted postoperative E-RFS (≤ 2 years), L-RFS (> 2 years), and OS for very early to intermediate-stage HCCs. CLINICAL RELEVANCE STATEMENT: The prognostic MRI features may help inform personalized surgical planning, neoadjuvant/adjuvant therapies, and postoperative surveillance, thus may be included in future prognostic models. KEY POINTS: • Tumor size, multiple tumors, rim arterial phase hyperenhancement, iron sparing, tumor growth pattern, and gastroesophageal varices predicted both recurrence-free survival within 2 years and overall survival. • Nonperipheral washout, markedly low apparent diffusion coefficient value, intratumoral arteries, and width of the main portal vein specifically predicted recurrence-free survival within 2 years, while the VICT2 trait specifically predicted overall survival. • Multiple tumors and radiologically-evident cirrhosis were the only predictors for recurrence-free survival beyond 2 years.

Current research status of traditional Chinese medicine in the prevention and treatment of hepatocellular carcinoma by regulating the JAK/STAT signaling pathway / 临床肝胆病杂志

Hepatocellular carcinoma （HCC） is one of the common malignant tumors of the digestive tract and seriously threatens the life of patients due to a high incidence rate， a high degree of malignancy， strong invasion and metastasis， and poor prognosis. At present， the main methods for the prevention and treatment of HCC include drugs， surgery， and interventional treatment， but all of these methods have certain adverse reactions and side effects. As an important intracellular signal transduction pathway in the human body， the JAK/STAT signaling pathway mainly exerts an anti-HCC effect by regulating cell invasion， metastasis， proliferation， growth， apoptosis， autophagy， angiogenesis， inflammation/immune response， iron metabolism， and drug resistance. Therefore， targeting the JAK/STAT signaling pathway plays an important role in the prevention and treatment of the development and progression of HCC. Traditional Chinese medicine has attracted wide attention due to its advantages of multiple targets， pathways， components， and levels in the treatment of HCC， and many cell or animal experiments on traditional Chinese medicine in the treatment of HCC have shown that the JAK/STAT signaling pathway is an important target for the prevention and treatment of HCC， with the effects of improving liver function， reducing HCC recurrence， and improving immunity. Based on this， this article analyzes the mechanism of action of the JAK/STAT signaling pathway in HCC， as well as the intervention effect of traditional Chinese medicine monomers， traditional Chinese medicine extracts， and traditional Chinese medicine compounds on the JAK/STAT signaling pathway， in order to provide theoretical basis and reference for the prevention and treatment of HCC and the research and development of new traditional Chinese medicine drugs.

Biological connotation of "phlegm-turbidity" theory in hepatocellular carcinoma microenvironment based on abnormal lipid metabolism / 临床肝胆病杂志

There is still a lack of effective strategies for the prevention and treatment of liver cancer, and a deep understanding of its pathogenesis may help to develop new treatment methods. Due to the abnormal changes of lipid metabolism in the development and progression of liver cancer, such process is closely associated with the "phlegm-turbidity" theory in traditional Chinese medicine (TCM). Starting from the changes of lipid metabolism in hepatocellular carcinoma microenvironment, this article discusses the association of the abnormal changes of lipid metabolism in tumor cells and immune cells with the "phlegm-turbidity" theory and the clinical efficacy of phlegm-eliminating therapies in clinical practice. Since the "phlegm-turbidity" theory in TCM plays an important role in the pathogenesis and pathological changes of liver cancer, the analysis of its theoretical connotation helps to clarify pathological mechanism, thereby providing a theoretical basis for the role of TCM in the prevention and treatment of liver cancer.

Overall survival and toxicity of Y90 radioembolization for hepatocellular carcinoma patients in Barcelona Clinic Liver Cancer stage C (BCLC-C).

INTRODUCTION: National Comprehensive Cancer Network HCC guidelines recommend Y90 to treat BCLC-C patients only in select cases given the development of systemic regimens. We sought to identify ideal candidates for Y90 by assessing survival and toxicities in this patient group. MATERIALS AND METHODS: The Radiation-Emitting Selective Internal radiation spheres in Non-resectable tumor registry is a prospective observational study (NCT: 02,685,631). Patients with advanced HCC were stratified into 3 groups based on tumor location, Eastern Cooperative Oncology Group (ECOG) performance status, and liver function. Group 1: liver isolated HCC, ECOG 0 and Child Pugh (CP) A (n = 12, 16%), Group 2: liver isolated HCC, ECOG ≥ 1 or CP B/C (n = 37, 49%), and Group 3: extrahepatic HCC with any ECOG or CP score (n = 26, 35%). Patients in any group could have macrovascular invasion. Overall survival (OS) and progression-free survival (PFS) with 95% confidence intervals (95% CI) were calculated. Grade 3 + toxicities were tracked using Common Terminology Criteria for Adverse Events v5. Cox proportional hazard model was performed to determine factors affecting OS. RESULTS: Seventy-five BCLC-C patients treated between 2015 and 2019 were reviewed. The groups were similar in age, sex, race, and ethnicity (all p > 0.05). Bilobar disease was least common in Group 1 (p < 0.001). Median OS of the entire cohort was 13.6 (95% CI 7.5-16.1) months. Median OS of Groups 1-3 were 21.8, 13.1 and 11.5 months respectively (p = 0.6). Median PFS for the cohort was 6.3 (4.8-14.7) months. Median PFS for group 1 was not reached. Mean PFS for Group 1 was 17.3 ± 4.8 months. Median PFS for Groups 2 and 3 was 6.8 and 5.9 months (X2 = 1.5, p = 0.5). Twenty-four Grade 3 or greater toxicities developed, most commonly hyperbilirubinemia (8/75, 11%) and thrombocytopenia (2/75, 3%). The incidence of toxicities between groups was similar (all p > 0.05). Cox Proportional Hazard analysis predicted shorter OS with CP class B/C (X2 = 6.7, p = 0.01), while macrovascular invasion (X2 = 0.5, p = 0.5) and ECOG score of ≥ 1 (X2 = 2.1, p = 0.3) was not associated with OS. CONCLUSIONS: OS of CPA patients with advanced HCC and performance status of 0 was 21.8 months following Y90. CP A cirrhosis is the best predictor of prolonged OS in advanced (BCLC-C) HCC.

Transcriptome profile and its partly verification of human hepatocellular carcinoma cells exposed to Yuzhizi () seed extract.

OBJECTIVE: To investigate the efficacy of Yuzhizi seed extract (FAQSE) on inhibiting the proliferation of hepatocellular carcinoma (HCC) cells in vitro and to explore the anti-HCC action mechanism of FAQSE. METHODS: Human HCC HepG2 and Huh7 cells were used to investigate the anti-HCC effect of FAQSE. 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyl tetrazolium bromide (MTT) method was used to measure cell viability. Affymetrix microarray was adopted to detect the expression of transcriptome. The differentially expressed genes (DEGs) of each cell line were identified. For co-DEGs of both cell lines, the gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway were enriched using the Database for Annotation, Visualization and Integrated Discovery (DAVID), and the network analysis of protein-protein interaction (PPI) was mapped using the Retrieval of Interacting Genes/Proteins (STRING) and Cytoscape software. Some important genes in the PPI network of co-DEGs were selected to verify by quantitative real-time reverse transcription-polymerase chain reaction, Western blot and enzyme-linked immunosorbent assay. RESULTS: FAQSE decreased the viability of HepG2 and Huh7 cells. There were 211 co-upregulated and 86 co-downregualted genes in both cell lines after FAQSE treatment. The enriched GO terms of co-upregulated DEGs were primarily involved cell-cell adhesion, viral process, transcription initiation from RNA polymerase II promoter, positive regulation of transcription from RNA polymerase II promoter and actin cytoskeleton organization. The GO terms of co-downregulated DEGs were mainly enriched in the processes of SRP-dependent cotranslational protein targeting to membrane, viral transcription, nuclear-transcribed mRNA catabolic process, nonsense-mediated decay, translational initiation and rRNA processing. Main KEGG pathways of co-upregulated DEGs were endocytosis, glutathione metabolism, protein processing in endoplasmic reticulum, synaptic vesicle cycle and lysosome. The major KEGG pathways of co-downregulated DEGs were ribosome, biosynthesis of amino acids, arginine and proline metabolism, systemic lupus erythematosus and complement and coagulation cascades. The top 10 co-DEGs with high hub nodes in STRING analysis were ribosomal protein S27a, transferrin, ribosomal protein S20, ribosomal protein L9, protein phosphatase 2 regulatory subunit B alpha, transthyretin, thioredoxin reductase 1, ribosomal protein L3, ribophorin I and ribosomal protein L24. Alpha-fetoprotein (AFP) was also co-downregulated and contained in the PPI network. The mRNA and protein expression of most verified genes was consistent with the results of co-DEGs analysis. And the AFP level was significantly reduced after FAQSE treatment. CONCLUSIONS: A series of genes and pathways of HepG2 and Huh7 cells were changed after FAQSE treatment, which might be the targets of FAQSE against HCC and worthy of further study. AFP might be important one of them.

Effectiveness of Jiedu granule on gut microbiota in patients with advanced hepatocellular carcinoma: a randomized controlled trial.

OBJECTIVE: To observe whether Jiedu granule (, JDG) modulates the composition of the gut microbiota during advanced hepatocellular carcinoma (HCC). METHODS: A randomized controlled trial was conducted. Sixty-two advanced HCC participants were randomly allocated to receive JDG or placebo. The median overall survival (OS) times of patients and the variation of relative abundance of bacteria over time were used as main outcome measures. RESULTS: Patients who received JDG demonstrated significantly longer median OS times compared with the placebo group. Pyrosequencing of the V3 regions of 16S rRNA genes revealed a dose dependent deviation of gut microbiota in response to JDG treatment. Redundancy analysis identified and Peptostre-ptococcaceae which related to the onset of liver cancer disappeared after 1-month and 2-month JDG treatment, while in control group, no significant changes of these two bacteria were found. The variation tendency of relative abundance of (essential in immunoblocking therapy of tumor) in JDG group was not obvious while in control group, it was decreased significantly with time. The relative abundance of (correlated with the occurrence of liver cancer) was increased in JDG group and was decreased in control group over time. CONCLUSION: Changes in the gut microbiota may be associated with the efficiency of JDG on survival period of advanced HCC patients. Trial registration：Chinese Clinical TRIAL Registry ChiCTR-OOC-16008002.

Comparison of metabolic and immunologic responses to transarterial chemoembolization with different chemoembolic regimens in a rabbit VX2 liver tumor model.

OBJECTIVES: The goal of this study was to investigate the effects of TACE using Lipiodol, Oncozene™ drug-eluting embolics (DEEs), or LUMI™-DEEs alone, or combined with bicarbonate on the metabolic and immunological tumor microenvironment in a rabbit VX2 tumor model. METHODS: VX2 liver tumor-bearing rabbits were assigned to five groups. MRI and extracellular pH (pHe) mapping using Biosensor Imaging of Redundant Deviation in Shifts (BIRDS) were performed before and after intra-arterial therapy with conventional TACE (cTACE), DEE-TACE with Idarubicin-eluting Oncozene™-DEEs, or Doxorubicin-eluting LUMI™-DEEs, each with or without prior bicarbonate infusion, and in untreated rabbits or treated with intra-arterial bicarbonate only. Imaging results were validated with immunohistochemistry (IHC) staining of cell viability (PCNA, TUNEL) and immune response (HLA-DR, CD3). Statistical analysis was performed using Mann-Whitney U test. RESULTS: pHe mapping revealed that combining cTACE with prior bicarbonate infusion significantly increased tumor pHe compared to control (p = 0.0175) and cTACE alone (p = 0.0025). IHC staining revealed peritumoral accumulation of HLA-DR+ antigen-presenting cells and CD3 + T-lymphocytes in controls. cTACE-treated tumors showed reduced immune infiltration, which was restored through combination with bicarbonate. DEE-TACE with Oncozene™-DEEs induced moderate intratumoral and marked peritumoral infiltration, which was slightly reduced with bicarbonate. Addition of bicarbonate prior to LUMI™-beads enhanced peritumoral immune cell infiltration compared to LUMI™-beads alone and resulted in the strongest intratumoral immune cell infiltration across all treated groups. CONCLUSIONS: The choice of chemoembolic regimen for TACE strongly affects post-treatment TME pHe and the ability of immune cells to accumulate and infiltrate the tumor tissue. KEY POINTS: • Combining conventional transarterial chemotherapy with prior bicarbonate infusion increases the pHe towards a more physiological value (p = 0.0025). • Peritumoral infiltration and intratumoral accumulation patterns of antigen-presenting cells and T-lymphocytes after transarterial chemotherapy were dependent on the choice of the chemoembolic regimen. • Combination of intra-arterial treatment with Doxorubicin-eluting LUMI™-beads and bicarbonate infusion resulted in the strongest intratumoral presence of immune cells (positivity index of 0.47 for HLADR+-cells and 0.62 for CD3+-cells).

Role of traditional Chinese medicine in treatment of chronic hepatitis B by nucleos(t)ide analogues / 临床肝胆病杂志

Nucleos(t)ide analogues (NUC) can inhibit the replication of hepatitis B virus (HBV) and effectively treat chronic hepatitis B (CHB), but they cannot completely eradicate HBV and cannot prevent the progression to hepatitis B cirrhosis and liver cancer in the context of a low viral load. In recent years, traditional Chinese medicine has been widely used in the treatment of CHB. This article elaborates on the application and mechanism of traditional Chinese medicine in inhibiting HBV replication, reducing the content of HBeAg, and delaying the progression to hepatitis B cirrhosis, and it is proposed that traditional Chinese medicine can improve the therapeutic effect of NUC in the treatment of CHB.

Role of transcription factor Yin Yang 1 in hepatocellular carcinoma / 临床肝胆病杂志

Hepatocellular carcinoma (HCC) often has an insidious onset, and most patients are in the advanced stage and have lost the best opportunity for treatment at the time of diagnosis, resulting in a poor prognosis. As a multifunctional transcription factor, Yin Yang 1 (YY1) regulates the transcription of a variety of important genes and plays a key role in various tumors. Previous studies have shown that YY1 affects many biological behaviors such as proliferation, apoptosis, migration, and angiogenesis and is closely associated with drug resistance and poor prognosis of HCC. This article reviews the research advances in the role of YY1 in the development and progression of HCC, so as to provide a theoretical basis for the treatment of HCC.

Recent studies have shown that traditional Chinese medicine plays an important role in the comprehensive treatment of HCC. Huaier granules have been recommended for the treatment of HCC, and its mechanism of action includes inhibiting angiogenesis, inhibiting the proliferation of HCC cells, inhibiting invasion and metastasis, inducing cell apoptosis, and regulating immune function. This article summarizes the research advances in the anti-HCC mechanism of Huaier granules and its application in clinical practice, in order to provide a reference for subsequent research and clinical treatment.

Role of lysyl oxidase family in the development and progression of hepatocellular carcinoma / 临床肝胆病杂志

Lysyl oxidase (LOX) family is a group of copper-containing amine oxidases composed of LOX and LOX-like proteins (LOXL1, LOXL2, LOXL3, and LOXL4). It is overexpressed in tumor tissue and promotes tumor metastasis through covalent cross-linking of extracellular matrix, with the functions of cell growth control, tumor inhibition, senescence, and chemotaxis. In recent years, more and more evidence has shown that LOX family members play a key role in the pathogenesis of hepatocellular carcinoma (HCC), suggesting that they have great potential as therapeutic targets. This article reviews the role of LOX family members in the development and progression of HCC and the intervention effect of traditional Chinese medicine extracts on HCC by regulating LOX family, in order to provide a reference for further research on the prevention and treatment of HCC.

Intraarterial contrast-enhanced ultrasound to predict the short-term tumour response of hepatocellular carcinoma to Transarterial chemoembolization with Lipiodol.

BACKGROUND: Transarterial chemoembolization (TACE) is an effective locoregional therapy in hepatocellular carcinoma (HCC). However, it is difficult to predict the tumour response (TR) of TACE intraprocedurally. The aim of this study was to predict the TR after TACE (1-3 months) in HCC patients using intraprocedural intraarterial contrast enhanced ultrasound (IA-CEUS). METHODS: In this case-control study, consecutive patients who received TACE in our hospital from September 2018 to May 2019 were enrolled. IA-CEUS was performed before and after TACE. Postoperative contrast-enhanced liver MRI was performed 1-3 months after TACE as the gold standard. According to the modified Response Evaluation Criteria in Solid Tumours (mRECIST), ultrasonic manifestations were compared between the complete remission (CR) group and non-CR group by univariate and multivariate analyses. A logistic predictive model was established and validated, and its diagnostic efficiency was evaluated. RESULTS: Forty-four patients with sixty-one lesions were enrolled in the study. Multivariate analysis identified, the risk factors as a large lesion diameter (OR: 1.84; 95% confidence interval [CI]: 1.009, 3.080; P = 0.020), a larger dimension of non-enhancing area in superior mesenteric artery (SMA)-CEUS than the size in B-mode ultrasound preoperatively (OR: 3.379; 95% CI: 1.346,8.484; P = 0.010), presence of corona enhancement in hepatic artery (HA)-CEUS postoperatively (OR: 6.642; 95% CI: 1.214, 36.331; P = 0.029), and decreased corona enhancement thickness (per centimetre) postoperatively (OR: 0.025; 95% CI: 0.006,0.718; P = 0.025). The area under the receiver operating characteristic curve (AUROC) of the predictive model was 0.904 (95% CI: 0.804, 0.966; P < 0.001). The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value were 81.08, 91.67, 85.25, 93.75, and 75.86%, respectively. Leave-one-out cross-validation (LOOCV) showed that the accuracy was 77.05%. CONCLUSIONS: Intraprocedural IA-CEUS can be used to predict the TR in HCC patients after TACE.

Mechanism of total glucosides from Chishao (Radix Paeoniae Rubra) on proliferation and apoptosis of hepatocellular carcinoma cells via phosphatase and tensin homolog deleted on chromosome ten / phosphatidylinositol 3-kinase / protein kinase B signaling pathway.

OBJECTIVE: To investigate the possible molecular mechanism of total glycosides of Chishao (Radix Paeoniae Rubra) (TG-RPR) on proliferation and apoptosis of hepatocellular carcinoma cells. METHODS: The proliferation of TG-RPR on HepG2 cells was detected using the 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The apoptosis of HepG2 cells was measured by annexin V-FITC/double staining. The phosphatase and tensin homolog deleted on chromosome ten (PTEN) / phosphatidylinositol 3-kinase (PI3K) / protein kinase B (Akt) signaling pathway was evaluated by Western Blot and reverse transcription-polymerase chain reaction (RT-PCR). RESULTS: TG-RPR can up-regulation the expression of pro-apoptotic factors such as PTEN and BCL2-Associated X (Bax), down-regulation the expression of anti-apoptotic factors including B-cell lymphoma-2 (Bcl-2), PI3K, and Akt. CONCLUSION: TG-RPR significantly inhibits the proliferation of HepG2 cells in a dose-dependent manner and promotes apoptosis. These results demonstrated TG-RPR has significant inhibitory effect on HepG2 cells. These results identify a critical role of TG-RPR in proliferation and apoptosis of HepG2 cells via modulating PTEN/PI3K/Akt signaling pathway. TG-RPR may offer a promise as a potential pharmaceutical therapy for hepatocellular carcinoma.

Celastrol induces caspase-dependent apoptosis of hepatocellular carcinoma cells by suppression of mammalian target of rapamycin.

OBJECTIVE: To investigate the efficacy of celastrol treatment of hepatocellular carcinoma (HCC) cells in vitro and in vivo and to propose a mechanism of action. METHODS: A human HepG2 liver cancer cell line and a xenograft tumor model were used to investigate the effects of celastrol on HCC in vitro and in vivo. A CCK-8 kit was used to detect cell viability. Flow cytometry and terminal-deoxynucleoitidyl transferase mediated nick end labeling staining were used to detect apoptosis. Western blotting and immunohistochemistry were used to detect the expression of cleaved-caspase-3, cleaved-caspase-8, cleaved-caspase-9, cleaved-PARP, mammalian target of rapamycin (mTOR), and p-mTOR. Hematoxylin-eosin staining was used to observe the tissue morphology. RESULTS: Celastrol decreased the viability of HepG2 cells and induced apoptosis. Western blot assays indicated that celastrol up-regulated cleaved-caspase-3, cleaved-caspase-8, cleaved-caspase-9, and cleaved-PARP by inhibiting the phosphorylation of mTOR in HepG2 cells. Moreover, celastrol inhibited the tumor growth in a xenograft model. Celastrol also induced caspase-dependent apoptosis (up-regulation of cleaved-caspase- 3, -8, -9, and cleaved-PARP) and inhibited the activation of mTOR in vivo. CONCLUSION: Celastrol induces caspase-dependent apoptosis in HCC cells by inhibiting the activation of mTOR.

Herbal formula of Bushen Jianpi combined with sorafenib inhibits hepatocellular carcinoma growth by promoting cell apoptosis and blocking the cell cycle.

OBJECTIVE: To investigate the efficacy of an herbal formula of Bushen Jianpi ( BSJP) combined with sorafenib on hepatocellular carcinoma (HCC) in vitro and in vivo, and to study the underlying mechanisms of action. METHODS: BSJP, a mixture of 12 raw herbs, was extracted in 70% alcohol/30% water and freeze-dried into a powder. The in vitro effects of BSJP alone, sorafenib alone, and their combination on cell survival, apoptosis, and cell cycle distribution were evaluated in HCC cell lines HCCLM3, HepG2, and SMMC-7721. The expression of B-cell lymphoma-2 (Bcl-2), caspase-3, and caspase-9 in HCCLM3 cells was measured using Western blots after drug administration. The in vivo effects of BSJP and sorafenib were evaluated in a tumor surgical resection model using 4-week old male athymic BALB/c nude mice injected with HCCLM3 cells. Immunohistochemical analysis of tumor tissues was performed to evaluate the effects of BSJP alone, sorafenib alone, and their combination on the expression of caspase-3, caspase-9, and Bcl-2. RESULTS: BSJP decreased the survival rate of HCC cell lines, and the combination of BSJP and sorafenib further decreased the survival rate. BSJP significantly promoted cell apoptosis and blocked cell-cycle progression in HCCLM3, HepG2, and SMMC-7721 cells in a dose-dependent manner. Furthermore, the administration of BSJP and sorafenib inhibited the growth of HCCLM3 cell xenografts in nude mice, with no reduction in body weight. In vivo and in vitro experiments showed that BSJP combined with sorafenib could significantly decrease the expression of Bcl-2. CONCLUSION: Our findings suggest that the herbal formula of BSJP is a potential HCC antitumor agent.

Duration of response after DEB-TACE compared to lipiodol-TACE in HCC-naïve patients: a propensity score matching analysis.

OBJECTIVES: To retrospectively compare long-term outcomes of first-line drug-eluting particle (DEB)- transarterial chemoembolization (TACE) and lipiodol-TACE, in patients with unresectable hepatocellular (HCC). METHODS: We retrospectively reviewed our database to identify adult patients with treatment-naïve unresectable HCC, who underwent TACE from 2006 to 2013. Patients were excluded in the absence of complete medical records relative to first TACE, 1-month follow-up, and/or sufficient follow-up data. Periprocedural complications, duration of hospitalization, 1-month tumor response by mRECIST, time to tumor progression (TTP) and target tumor progression (TTTP), and overall survival (OS) were evaluated. RESULTS: Out of an initial series of 656 patients, 329 patients were excluded for unavailability of sufficient baseline and/or follow-up data. The remaining 327 patients underwent either lipiodol-TACE (n = 160) or DEB-TACE (n = 167). Patients treated with lipiodol-TACE had a significantly higher tumor burden. By propensity score, patients were matched according to baseline differences (BCLC stage, uninodular or multinodular HCC, and unilobar or bilobar HCC), resulting in 101 patients in each treatment group. Lipiodol-TACE was associated with a significantly higher incidence of adverse events (p = 0.03), and longer hospitalization (mean, 2.5 days vs 1.9 days; p = 0.03), while tumor response, TTP, and OS were comparable. In patients achieving 1-month complete response (CR) of target tumor, TTTP was significantly (p = 0.009) longer after DEB-TACE compared to lipiodol-TACE (median, 835 vs 353 days), resulting in a lower number of re-treatments during the entire follow-up (0.75 vs 1.6, p = 0.01). CONCLUSION: Compared to lipiodol-TACE, DEB-TACE offers higher tolerability, reduced hospitalization, and more durable target tumor response after CR. KEY POINTS: • Compared to lipiodol-TACE, DEB-TACE is better tolerated and has reduced side effects, which translates into shorter hospitalization. • When complete radiological response according to the mRECIST is obtained 1 month after the procedure, DEB-TACE offers a more durable local tumor control compared to lipiodol-TACE. • In these patients, the longer duration of response after DEB-TACE translates into a lower number of re-interventions.

Early prediction of 1-year tumor response of hepatocellular carcinoma with lipiodol deposition pattern through post-embolization cone-beam computed tomography during conventional transarterial chemoembolization.

OBJECTIVE: To evaluate whether parenchyma-to-lipiodol ratio (PLR) and lesion-to-lipiodol ratio (LLR) on C-arm cone-beam computed tomography (CBCT) can predict 1-year tumor response in patients with hepatocellular carcinoma (HCC) treated with conventional transcatheter arterial chemoembolization (cTACE). METHODS: This retrospective analysis included 221 HCC target lesions within up-to-seven criteria in 80 patients who underwent cTACE with arterial-phase CBCT and unenhanced CBCT after cTACE from 2015 to 2018. PLR and LLR of every tumor slice were obtained through mean density division of liver parenchyma and tumor enhancement with intratumoral lipiodol deposition. The cutoff values (COVs) of maximal PLR and LLR of every tumor were analyzed using Youden's index. The reliability of COV, correlations between the related parameters, and 1-year progression were assessed through interobserver agreement and multivariate analysis. COV validity was verified using the chi-square test and Cramer's V coefficient (V) in the validation cohort. RESULTS: Standard COVs of PLR and LLR were 0.149 and 1.4872, respectively. Interobserver agreement of COV for PLR and LLR was near perfect (kappa > 0.9). Multivariate analysis suggested that COV of PLR is an independent predictor (odds ratio = 1.23532×1014, p = 4.37×10-7). COV of PLR showed strong consistency, correlation with 1-year progression in prediction model (V = 0.829-0.776; p < 0.0001), and presented as an effective predictor in the validation cohort (V = 0.766; p < 0.0001). CONCLUSION: The COV of PLR (0.149) assessed through immediate post-embolization CBCT is an objective, effective, and approachable predictor of 1-year HCC progression after cTACE. KEY POINTS: • The maximal PLR value indicates the least lipiodol-distributed region in an HCC tumor. The maximal LLR value indicates the least lipiodol-deposited region in the tumor due to incomplete lipiodol delivery. PLR and LLR are concepts like signal-to-noise ratio to characterize the lipiodol retention pattern objectively to predict 1-year tumor progression immediately without any quantification software for 3D image analysis immediately after cTACE treatment. • COV of PLR can facilitate the early prediction of tumor progression/recurrence and indicate the section of embolized HCC, providing the operator's good targets for sequential cTACE or combined ablation. • The validation cohort in our study verified standard COVs of PLR and LLR. The validation process was more convincing and delicate than that of previous retrospective studies.

Therapeutic effect of Jianpi Liqi Fang combined with transcatheter arterial chemoembolization in patients with hepatocellular carcinoma and spleen deficiency syndrome.

OBJECTIVE: To investigate the therapeutic effect of the Jianpi Liqi Fang ( ，JPLQF) combined with transcatheter arterial chemoembolization (TACE) in patients with hepatocellular carcinoma (HCC) and spleen deficiency syndrome (SDS) and identify a potential indicator of efficacy. METHODS: Ninety-nine patients with HCC who were diagnosed with SDS, non-spleen deficiency syndrome (NSDS), or no syndrome (NS) were treated with JPLQF combined with TACE for three periods. Therapeutic efficacy was compared among the groups. Plasma proteins were screened using label-free discovery analysis and verified via enzyme-linked immunosorbent assay (ELISA). Furthermore, receiver operating characteristic (ROC) curves were analyzed to evaluate therapeutic indicators. RESULTS: After treatment, the Karnofsky Performance Status was significantly improved in the SDS group and significantly better than that in the NS group. The Traditional Chinese Medicine (TCM) syndrome scores were lower in the SDS group after treatment and lower than those in the NSDS group. However, alanine aminotransferase, carbohydrate antigen 19-9, alpha-fetoprotein, and carcinoembryonic antigen levels and white blood cell and platelet counts did not differ among the groups. Serum aspartate aminotransferase levels in the SDS group were significantly lower after treatment than before treatment, and total bilirubin levels were significantly lower in the SDS group than in the NSDS group. Label-free analysis identified 24 differentially expressed proteins (DEPs) between the SDS and NS groups, including 17 and 7 upregulated and downregulated proteins, respectively. Fibulin-5 (FBLN5) displayed the largest difference in expression between the groups. ELISA confirmed that FBLN5 levels were significantly lower in the NSDS and NS groups than in the SDS group. Following treatment with JPLQF and TACE, FBLN5 expression was upregulated only in the SDS group. Furthermore, ROC curve analysis indicated that FBLN5 may serve as a potential indicator of the efficacy of JPLQF combined with TACE in patients with HCC and SDS. CONCLUSION: JPLQF combined with TACE improved quality of life, clinical TCM symptoms, and liver function in patients with HCC and SDS. FBLN5 expression was significantly altered by treatment with JPLQF and TACE in patients with HCC and SDS.

Expression and clinical significance of forkhead box A2 and forkhead box J2 in hepatocellular carcinoma / 临床肝胆病杂志

ObjectiveTo investigate the expression levels of forkhead box A2 (FOXA2) and forkhead box J2 (FOXJ2) in hepatocellular carcinoma (HCC) tissue and the association of FOXA2 and FOXJ2 with HCC. MethodsClinical data and pathological tissue samples were collected from 54 patients with pathologically confirmed HCC in The First Affiliated Hospital of Henan University of Traditional Chinese Medicine from January 2014 to July 2019. The immunohistochemical SP method was used to measure the protein expression levels of FOXA2 and FOXJ2 in HCC tissue, and their association with HCC-related clinicopathological features and patient prognosis was analyzed. The chi-square test and the adjusted chi-square test were used for comparison of categorical data; a Spearman correlation analysis was performed to investigate the correlation between the expression of FOXA2 and FOXJ2; the Kaplan-Meier method was used for survival analysis; Image-Pro Plus was used to perform the semi-quantitative analysis of the expression of FOXA2 and FOXJ2; the Wilcoxon rank-sum test was used for comparison between groups. ResultsThe positive rates of the protein expression of FOXA2 and FOXJ2 in HCC tissue were 70.37% (38/54) and 75.92% (41/54), respectively, and there was a significant positive correlation between the expression levels of FOXA2 and FOXJ2 (rs=0.648, P＜0.001). In both negative and positive groups, the expression level of FOXA2 was associated with tumor diameter, degree of tumor differentiation, number of tumors, and alpha-fetoprotein (χ2=5.440, 4.113, 4.352, and 3.865, P=0.020, 0.043, 0037, and 0.049), and the expression level of FOXJ2 was associated with the degree of tumor differentiation (χ2=9.267, P=0.002). The group with positive expression of FOXA2 and FOXJ2 had a significantly higher cumulative survival rate than the group with negative expression of FOXA2 and FOXJ2 (P＜0.01). ConclusionThe expression levels of FOXA2 and FOXJ2 are associated with the development, progression, and prognosis of HCC, and they have a synergistic effect in the development and progression of HCC.
