Rethinking the Barcelona clinic liver cancer guidelines: Intermediate stage and Child-Pugh B patients are suitable for surgery?

The effect of stored autologous blood transfusion on IL-1, IL-6, TNF-α and liver function recovery in patients undergoing liver cancer surgery

PURPOSE

This study aim is to evaluate the application of stored autologous blood transfusion in liver cancer surgery and explore its impact on postoperative changes in inflammatory factors and liver function recovery.

METHOD

The study used a control group (CG) design and included 150 patients who underwent liver cancer surgery. While the observation group (OG) got autologous blood that had been preserved, the CG had a standard allogeneic blood transfusion. Examine the variations between the CG and the OG using the following measures: prior to, during, and following surgery contrast MELD score, blood routine indicators, pro-inflammatory cytokine levels.

RESULT

MELD ratings, IL-1, IL-6, TNF-α levels, and preoperative blood routine indicators did not differ between the observation and CGs (p > 0.05). However, the blood routine indicators in the OG were lower than those in the CG on the first day following surgery (p < 0.05); seven days following surgery, there was no significant difference among the experiment participants (p > 0.05). In the meanwhile, the postoperative OG's levels of IL-1, IL-6, TNF-α, and HAF were lower than those of the CG (p < 0.05). The PVF of the OG was lower than the CG on the first day following surgery (p < 0.05), but on the seventh day following surgery, there was no discernible difference between the experiment's participants (p > 0.05).

CONCLUSION

The research outcomes showcase that stored autologous blood transfusion can reduce the levels of inflammatory factors after surgery and promote the recovery of liver function;Research suggests important references for further understanding the application and mechanism of stored autologous blood transfusion, and provide a basis for personalized treatment and recovery of liver cancer patients undergoing surgery.

High tumor burden score indicated the unfavorable prognosis in patients with hepatocellular carcinoma: A meta-analysis

BACKGROUND

Tumor burden score (TBS) based on maximum tumor diameter and number has been shown to correlate with prognosis in patients with hepatocellular carcinoma (HCC). Nevertheless, the results are conflicting. Hence, we conducted a meta-analysis to analyze the association between TBS and survival outcomes of HCC patients.

METHODS

A comprehensively search of the databases including PubMed, Embase and Web of Science was performed to retrieve studies satisfying the inclusion criteria until August 31, 2023. The hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated. All the data analyses were carried out by STATA 12.0.

RESULTS

10 retrospective studies containing 25073 patients were incorporated in the study. The results demonstrated that high TBS was markedly association with poor overall survival (OS) (HR: 1.79, 95% CI: 1.45-2.23) and relapse-free survival / progression-free survival(RFS/PFS) (HR: 1.71; 95% CI: 1.42-2.07). Subgroup analysis showed that the prognostic value of TBS in HCC was not affected by any subgroup.

CONCLUSIONS

TBS may be an efficient prognostic index in HCC patients.

Treating liver cancer through arginine depletion

Liver cancer, the sixth most common cancer globally and the second-leading cause of cancer-related deaths, presents a critical public health threat. Diagnosis often occurs in advanced stages of the disease, aligning incidence with fatality rates. Given that established treatments, such as stereotactic body radiation therapy and transarterial radioembolization, face accessibility and affordability challenges, the emerging focus on cancer cell metabolism, particularly arginine (Arg) depletion, offers a promising research avenue. Arg-depleting enzymes show efficacy against Arg-auxotrophic cancers, including hepatocellular carcinoma (HCC). Thus, in this review, we explore the limitations of current therapies and highlight the potential of Arg depletion, emphasizing various Arg-hydrolyzing enzymes in clinical development.

A Longitudinal Study of AFP Trajectories and Clinical Outcomes in Intermediate-Stage Hepatocellular Carcinoma After Hepatectomy

Background

Previous studies have shown that the alpha-fetoprotein (AFP) response has been a key tumour marker in hepatocellular carcinoma (HCC), but its definition remains controversial. Recently, a new study has explored and defined the AFP serological response and used it to explain the subclass of intermediate-stage hepatocellular carcinoma (IM-HCC) with "sharp-falling" AFP change after transarterial chemoembolization (TACE). It may be a new and simple tool for assessing the prognosis of patients. This study aims to explore a simplified AFP trajectory and its impact on overall survival (OS) and disease-free survival (DFS) for IM-HCC after hepatectomy.

Patients and Methods

Between January 2007 and May 2012, data from the Sun Yat-sen University Cancer Center was examined in this longitudinal, retrospective cohort study. A generalized additive model was applied to distinguish potential AFP dynamic trajectories. The Kaplan-Meier method was applied to analyze OS and DFS, and multivariate Cox models were used to calculate adjusted hazard ratios (aHRs) and 95% CIs for overall survival.

Results

144 patients who had IM-HCC with at least three AFP repeat measurements were included in the study. Three similar trajectories are displayed using the generalized additive model: low-stable (35.4%; n = 51), high-rising (36.1%; n = 52), and sharp-falling (28.5%; n = 41). Compared with the low-stable class, the aHRs for death were 2.84 (1.50, 5.41) and 0.59 (0.25, 1.40) for the high-rising and sharp-falling classes, adjusted by age and log AFP. Simplified AFP trajectory had higher relative importance than sex, intrahepatic tumor number, Child-Pugh class, and baseline AFP.

Conclusion

The simplified AFP trajectory is a promising biomarker for IM-HCC patients undergoing hepatectomy. In the future, it should be verified by a larger population containing various stages of HCC.

hsa_circ_0002980 prevents proliferation, migration, invasion, and epithelial-mesenchymal transition of liver cancer cells through microRNA-1303/cell adhesion molecule 2 axis

BACKGROUND

Liver cancer (LC) is a rare malignancy. Circular RNA (circRNA) dysregulation is associated with LC metastasis. hsa_circ_0002980 was found to be unexpectedly downregulated in LC tissues; however, its specific function remains unclear.

METHODS

hsa_circ_0002980 expression was confirmed using RT-qPCR. The effects of circ_0002980 on the proliferation, metastasis, and EMT-related proteins of LC cells were assessed using clone formation, flow cytometry, Transwell assays, and Western blotting. The relationship between circ_0002980 and miR-1303 or miR-1303 and CADM2 was analyzed using a dual-luciferase reporter assay. Thereafter, the influence of these three genes on LC cell progression was determined through rescue experiments.

RESULTS

hsa_circ_0002980 expression was lower in LC. circ_0002980 overexpression inhibited the proliferation, migration, invasion, and EMT of LC cells. In addition, circ_0002980 specifically binds to miR-1303, and the accelerated effect of miR-1303 overexpression on LC progression was partially reversed by circ_0002980. Moreover, miR-1303 can also target CADM2, and CADM2-mediated prevention can also be attenuated by miR-1303 overexpression.

CONCLUSIONS

In LC cells, circ_0002980 upregulation prevents cell proliferation, metastasis, and EMT by affecting the miR-1303/CADM2 axis. Therefore, this axis may be a novel therapeutic target in LC.

Efficacy and safety of anlotinib as an adjuvant therapy in hepatocellular carcinoma patients with a high risk of postoperative recurrence

Objective

Hepatocellular carcinoma (HCC) has a high rate of postoperative recurrence and lacks an effective treatment to prevent recurrence. This study aims to investigate the efficacy and safety of anlotinib in postoperative adjuvant therapy for HCC patients with high-risk recurrence factors.

Methods

For this multicenter, retrospective study, we recruited 63 HCC patients who received either anlotinib (n=27) or transcatheter arterial chemoembolization (TACE) (n=36) from six research centers in China between March 2019 and October 2020. The primary endpoint was disease-free survival (DFS) and the secondary endpoints were overall survival (OS) and safety.

Results

In this study, the median follow-up time was 25.9 and 26.8 months in the anlotinib and TACE groups, respectively. There was no significant difference in the median DFS between the anlotinib [26.8 months, 95% confidence interval (95% CI): 6.8-NE] and TACE groups (20.6 months, 95% CI: 8.4-NE). The 12-month OS rates in the anlotinib and TACE groups were 96.3% and 97.2%, respectively. In the anlotinib group, 19 of 27 patients (70.4%) experienced treatment-emergent adverse events, with the most common events (≥10%) being hypertension (22.2%) and decreased platelet count (22.2%).

Conclusions

The results indicate that anlotinib, as a new, orally administered tyrosine kinase inhibitor, has the same efficacy as TACE, and side effects can be well controlled.

Current management of liver diseases and the role of multidisciplinary approach

Liver is an organ having extremely diversified functions, ranging from metabolic and synthetic to detoxification of harmful chemicals. The multifunctionality of the liver in principle requires the multidisciplinary and pluralistic interventions for its management. Several studies have investigated liver function, dysfunction and clinic. This editorial work discusses new ideas, challenges and perspectives of current research regarding multidisciplinary and pluralistic management of liver diseases. In one hand the discussions have carried out on the involvement of extracellular vesicles, Na⁺/H⁺ exchangers, severe acute respiratory syndrome coronavirus 2 and Epstein–Barr virus infections, Drug-induced liver injury, sepsis, pregnancy, and food supplements in hepatic disorders. In the other hand this study has discussed hepatocellular carcinoma algorithms and new biochemical and imaging experiments pertaining to liver diseases. Relevant articles with an impact index value "> 0" from reference citation analysis, which is an open multidisciplinary citation analysis database based on artificial intelligence technology, have served for the study’s argumentation. This work may be a useful tool for the clinical practice and research in managing and investigating liver disorders.

Comprehensive Review of Hepatocellular Carcinoma in India: Current Challenges and Future Directions

There is not much information on hepatocellular carcinoma (HCC) in India. Here, we review the existing data, available treatment choices, and future directions in HCC management. An extensive search was conducted through PubMed and MEDLINE for studies published between January 2000 and June 2022 on the epidemiology of HCC in India using the following key words: atezolizumab, BCLC staging, hepatocellular carcinoma, immune checkpoint inhibitors, immunotherapy, and programmed cell death ligand-1, with the filters humans and English language. The most frequent risk factors for the development of HCC in India include nonalcoholic fatty liver disease, hepatitis B virus and hepatitis C virus infection, liver cirrhosis, and alcohol intake. On the basis of new findings, the Barcelona Clinic Liver Cancer (BCLC) Staging Criteria need to be revised. As most cases in India are discovered at a later stage, curative treatments such as surgical resection, ablation, or liver transplantation may not be an option. Clinical trials are underway for a number of immune checkpoint drugs that target cytotoxic T-cell lymphocyte-4 and programmed cell death-1/programmed cell death-ligand 1. In India, phase III trials of atezolizumab in combination with other drugs are underway for the treatment of various malignancies. Renin angiotensin system inhibitors, antivirals, primary hepatocyte transplantation, and bioartificial liver devices are among the future options for the management of HCC. In developing countries like India, HCC is often diagnosed at an advanced stage because of a delay in routine testing or screening. Therefore, developing effective treatment regimens for such stages is critical. Immunotherapy is a promising treatment option that has the potential to increase overall response and survival rate.

Iron-Based Nanoparticles Applied to Evaluate MRI Diagnosis and Treatment of Liver Cancer Treated with Apatinib

Objective: To investigate the value of iron-based nanoparticles in evaluating the magnetic resonance imaging (MRI) diagnosis and treatment of liver cancer treated with apatinib. Methods: Apatinib treatment and MRI were performed in patients with primary liver cancer. The characteristics of liver tissue sections and biodistribution in mice after injection of Fe2O3-PEG and iron oxide nanoparticles (Fe2O3-pep) were analyzed, and the MRI characteristics and magnetic resonance signals of Fe2O3-PEG and Fe2O3-pep nanoparticles were compared. Results: Fe2O3-PEG and Fe2O3-pep had little effect on the activity of human normal hepatocytes. There was no significant difference in liver tissue sections between mice injected with Fe2O3-PEG and Fe2O3-pep nanoparticles. The Fe2O3-PEG and Fe2O3-pep in the liver organs of mice were 11.3 and 9.7, which were significantly higher than those in other organs. At 12 hours and 24 hours after injection of Fe2O3-pep and Fe2O3-PEG nanoparticles, the signal at the tumor site decreased on T2WI images, the maximum contrast of magnetic resonance images was enhanced at 12 hours after injection, and the signal decrease was more significant in the group injected with Fe2O3-pep nanoparticles. Conclusion: Fe2O3-pep has higher tumor targeting and has positive application value in evaluating MRI diagnosis and treatment of liver cancer.

Combination approaches in hepatocellular carcinoma: How systemic treatment can benefit candidates to locoregional modalities

The management of hepatocellular carcinoma (HCC) is challenging because most patients have underlying cirrhosis, and the treatment provides, historically, a limited impact on the natural history of patients with advanced-stage disease. Additionally, recurrence rates are high for those patients who receive local and locoregional modalities, such as surgical (resection and transplantation) or image-guided (ablation and intra-arterial) therapies. Translational research has led to new concepts that are reshaping the current clinical practice. Substantial advancements were achieved in the understanding of the hallmarks that drive hepatocarcinogenesis. This has primed a successful incorporation of novel agents with different targets, such as anti-angiogenic drugs, targeted-therapies, and immune-checkpoint inhibitors. Although clinical trials have proven efficacy of systemic agents in advanced stage disease, there is no conclusive evidence to support their use in combination with loco-regional therapy. While novel local modalities are being incorporated (e.g., radioembolization, microwave ablation, and irreversible electroporation), emerging data indicate that locoregional treatments may induce tumor microenvironment changes, such as hyperexpression of growth factors, release of tumor antigens, infiltration of cytotoxic lymphocytes, and modulation of adaptative and innate immune response. Past trials that evaluated the use of antiangiogenic drugs in the adjuvant setting after ablation or chemoembolization fail to demonstrate a substantial improvement. Current efforts are directed to investigate the role of immunotherapy-based regimens in this context. The present review aims to describe the current landscape of systemic and locoregional treatments for HCC, present evidence to support combination approaches, and address future perspectives.

Effect of Transdermal Fentanyl Patch Combined with Enhanced Recovery after Surgery on the Curative Effect and Analgesic Effect of Liver Cancer

Its goal was to see how a transdermal fentanyl patch combined with accelerated recovery after surgery (ERAS) affected the treatment efficacy and analgesic effect of liver cancer, as well as to help patients with liver cancer choose the right analgesic treatment and nursing mode. 150 patients with liver cancer were divided into group A (transdermal fentanyl patch), group B (ERAS), and group C (transdermal fentanyl patch combined with ERAS). Patients in the three groups were compared in terms of pain, survival, psychological status, adverse responses, postoperative recovery, and patient satisfaction. The results showed that under different treatment and nursing methods, the number of patients with mild cancer pain in the three groups was increased, especially the number of patients with mild cancer pain in group C (P < 0.05). Besides, the quality of life score of patients in each group was decreased. Patients who received the combination analgesia had a significantly higher quality of life than those who received simply a transdermal fentanyl patch or ERAS (P < 0.05). The scores of both the Hamilton anxiety scale (HAMA) and Hamilton depression rating scale (HAMD) of patients with the combined analgesia were decreased signally (P < 0.05). There were few patients with combined analgesia who had adverse reactions (P < 0.05). After surgery, the time of the first anal exhaust, first defecation, and first ambulation in group C were shorter than those in the other two groups (P < 0.05). To summarize, combining the two techniques aided in the recovery of gastrointestinal function as well as the physical recovery of patients following surgery. Furthermore, combining the two approaches produced a clear analgesic impact, which could improve patients' quality of life while also having a favorable clinical adoption effect.

Conversion therapy of hepatic artery ligation combined with transcatheter arterial chemoembolization for treating liver cancer: A case report

BACKGROUND

Hepatocellular carcinoma is an aggressive tumor, and its latency and lack of clinical symptoms mean that most patients are already in the late stage when diagnosed. Large tumor volume and metastasis are the main reasons for not attempting surgery. Portal vein embolization and associated liver partition and portal vein ligation for staged hepatectomy are commonly used in clinical practice to increase the volume of remnant liver to allow surgical resection; however, research in this area is currently lacking.

CASE SUMMARY

A 48-year-old male patient with a history of viral hepatitis B for at least 30 years attended our center with a hepatic space-occupying lesion detected 3 d previously. Enhanced computed tomography scanning of the upper abdomen revealed a large mass in the right lobe of the liver, centered on the right posterior lobe, with the larger section measuring about 14 cm × 10 cm × 14 cm. He successfully underwent conversion therapy for a large right liver tumor after combined hepatic artery ligation and transcatheter arterial chemoembolization, and finally had an opportunity to undergo right hemi-hepatectomy and cholecystectomy. He remained asymptomatic with no obvious abnormalities on computed tomography scanning review at 2 mo after surgery.

CONCLUSION

This case highlights new ideas and provides a reference for conversion therapy of large liver tumors.
