RESUMO
BACKGROUND AND AIMS: The impacts of macrovascular invasion (MVI) or extrahepatic spread (EHS) on the efficacy and safety of immune checkpoint inhibitors (ICIs) among hepatocellular carcinoma (HCC) patients remain unclear. Thus, we conducted a systematic review and meta-analysis to clarify whether ICI therapy is a feasible treatment option for HCC with MVI or EHS. METHODS: Eligible studies published before September 14, 2022, were retrieved. In this meta-analysis, the objective response rate (ORR), progression-free survival (PFS), overall survival (OS), and occurrence of adverse events (AEs) were outcomes of interest. RESULTS: Fifty-four studies involving 6187 individuals were included. The findings indicated that the presence of EHS in ICI-treated HCC patients may indicate an inferior ORR (OR 0.77, 95% CI 0.63-0.96), but may not significantly affect the PFS (multivariate analyses: HR 1.27, 95% CI 0.70-2.31) and OS (multivariate analyses: HR 1.23, 95% CI 0.70-2.16). Additionally, the presence of MVI in ICI-treated HCC patients may not have significant prognostic impact on ORR (OR 0.84, 95% CI 0.64-1.10), but may indicate inferior PFS (multivariate analyses: HR 1.75, 95% CI 1.07-2.84) and OS (multivariate analyses: HR 2.03, 95% CI 1.31-3.14). The presence of EHS or MVI in ICI-treated HCC patients may not significantly impact the occurrence of any serious immune-related adverse events (irAEs) (grades ≥ 3) (EHS: OR 0.44, 95% CI 0.12-1.56; MVI: OR 0.68, 95% CI 0.24-1.88). CONCLUSION: The presence of MVI or EHS in ICI-treated HCC patients may not significantly impact the occurrence of serious irAEs. However, the presence of MVI (but not EHS) in ICI-treated HCC patients may be a significant negative prognostic factor. Therefore, ICI-treated HCC patients with MVI warrant more attention.

BACKGROUND: Preliminary studies have suggested that soluble programmed death-1 (sPD-1) and soluble programmed cell death ligand-1 (sPD-L1) have prognostic implications in many malignant tumors. However, the correlation between sPD-1/sPD-L1 level and prognosis of hepatocellular carcinoma (HCC) is still unclear. METHODS: We searched several electronic databases from database inception to October 7, 2021. Meta-analyses were performed separately for overall survival (OS), disease-free survival (DFS), recurrence-free survival (RFS), time to progression (TTP), and tumor-free survival (TFS). Random effects were introduced to this meta-analysis. The correlation between sPD-1/sPD-L1 level and prognosis was evaluated using hazard ratios (HRs) with 95% confidence intervals (95%CIs). RESULTS: A total of 11 studies (1291 patients) were incorporated into this meta-analysis, including seven on sPD-L1, two on sPD-1, and two about both factors. The pooled results showed that high sPD-L1 level was associated with worse OS (HR = 2.46, 95%CI 1.74-3.49, P < 0.001; I2 = 31.4, P = 0.177) and poorer DFS/RFS/TTP/TFS of patients with HCC (HR = 2.22, 95%CI 1.47-3.35, P < 0.001; I2 = 66.1, P = 0.011), irrespective of method of detection, study type, treatment, cut-off value and follow-up time. In contrast, the level of sPD-1 was not correlated to the OS (HR = 1.19, 95%CI 0.55-2.56, P = 0.657) and DFS/TFS of patients with HCC (HR = 0.94, 95%CI 0.36-2.49, P = 0.906). CONCLUSION: sPD-L1 rather than sPD-1 could be a good predictor for recurrence and survival after treatment for HCC. More high-quality prospective studies are warranted to assess the prognostic value of sPD-1 or sPD-L1 for HCC.

BACKGROUND: The prognostic value of alpha-fetoprotein (AFP) response for efficacy of targeted therapy or immune checkpoint inhibitors (ICIs) has not been established. The purpose of this meta-analysis is to elucidate the relationship between AFP response and survival outcomes in hepatocellular carcinoma (HCC) patients who received targeted therapy or ICIs. METHODS: The hazard ratio (HR) with 95% confidence interval (CI) was used to evaluate the relationship between AFP response and overall survival (OS)/progression-free survival (PFS). RESULTS: Twenty-six articles containing 3056 HCC patients were finally included in the study. The pooled results showed that after targeted therapy or ICIs, patients with decrease in AFP had better prognosis (OS:HR = 0.48, 95%CI:0.40-0.56; PFS:HR = 0.39, 95%CI:0.33-0.46), while patients with increase in AFP had worse prognosis (OS:HR = 2.30, 95%CI:1.82-2.89; PFS:HR = 2.34, 95%CI = 1.69-3.24). Subgroup analysis revealed that compared to AFP decrease >50%, AFP decrease >20% can better predict the prognosis of patients who received targeted therapy (OS:HR = 0.51, 95%CI:0.41-0.62; PFS:HR = 0.39, 95%CI:0.30-0.51) or ICIs treatment (OS:HR = 0.34, 95%CI:0.16-0.71; PFS:HR = 0.22, 95%CI:0.10-0.47), and 8 weeks after targeted therapy may be the appropriate time point for AFP assessment. CONCLUSION: AFP decrease >20% within 8 weeks may be the appropriate definition for early AFP response which probably works best in predicting the efficacy of therapy. REGISTRATION: The review was not registered.

BACKGROUND: Most patients with hepatocellular carcinoma (HCC) have underlying cirrhosis and a compromised liver function. Immune checkpoint inhibitors (ICIs) have emerged as an important approach for HCC treatment. The purpose of our study was to explore the prognostic significance of liver function in HCC patients receiving ICIs. METHODS: Hazard ratios (HR) with 95% confidence intervals (CI) were used to evaluate the relationship between liver function and overall survival (OS)/progression-free survival (PFS). RESULTS: 41 articles with 4483 patients with HCC were included. The pooled results revealed that either Child-Pugh score (OS:HR = 2.01,95 %CI:1.69-2.38; PFS:HR = 1.39,95 %CI:1.15-1.68) or albumin-bilirubin (ALBI) score (OS:HR = 2.04,95 %CI:1.55-2.69; PFS:HR = 1.42,95 %CI:1.21-1.67) can predict the patient prognosis. The Child-Pugh score has some degree of subjectivity, and the ALBI score can better stratify patients. Therefore, the ALBI score was used to evaluate patients' liver function and determine treatment options. Further subgroup analysis found that the results of prospective studies were statistically significant only for the ALBI score with regards to OS (HR = 1.69,95 %CI:1.26-2.26). Meanwhile, the effect of liver function on the efficacy of ICIs in the large-sample studies was not as obvious as that in small-sample studies. Moreover, the incidence of adverse events did not significantly increase in patients with impaired liver function. CONCLUSION: Poor liver function is associated with a poor prognosis in patients with HCC receiving ICIs. The ALBI score is simpler and reliable for patient stratification than the Child-Pugh score. Although the survival time of patients with impaired liver function may be relatively short, ICIs still have great potential for therapeutic applications.

The introduction of immune checkpoint inhibitors (ICIs) has reshaped the therapy of hepatocellular carcinoma (HCC). ICIs are a novel therapy with frequent adverse events (AEs), including treatment-related adverse events (trAEs) and immune-related adverse events (irAEs). However, no comprehensive overview of the toxicity spectrum of ICIs in HCC patients has been provided. Electronic databases were searched to identify eligible studies. A meta-analysis of the incidence rate of AEs in HCC patients treated with ICIs was performed. Lastly, the prognostic value of irAEs in HCC patients treated with ICIs was verified. Forty-seven studies with 6472 participations met the inclusion criteria. The pooled all-grade trAEs incidence rate was 83.4% (95% confidence interval [95% CI] 77.0-89.1%), ≥ grade 3 trAEs incidence rate was 33.0% (95% CI 26.9-39.5%), all-grade irAEs incidence rate was 34% (95% CI 22-47%), and ≥ grade 3 irAEs incidence rate was 9% (95% CI 5-14%). Aspartate aminotransferase (AST) increase (38%, 95% CI 35-40%) is the most common trAEs. Fatigue (14%, 95% CI 7-23%) is the most common irAEs. The pooled results also showed that 18.8% (95% CI 13.2-25.2%) of patients required systemic steroid therapy due to AEs, while 6.6% (95% CI 4.6-9.0%) of patients withdrew from treatment due to AEs. Additionally, patients experiencing irAEs may have a better progression-free survival (PFS) (multivariate analysis: hazard ratio [HR] = 0.41, 95% CI 0.27-0.61, I2 = 36.3%) but not overall survival (OS) (multivariate analysis: HR = 0.54, 95% CI 0.22-1.36, I2 = 83.2%) than those with no irAEs. Our study presents a systemic assessment of the AEs profile in HCC patients receiving ICIs, providing important reference for clinicians on toxicity profile. Besides, patients with irAEs may have a better PFS. More large-scale and prospective studies are needed to confirm our conclusions.

PURPOSE: Immune checkpoint inhibitors (ICIs) have been explored as first-line treatment in various types of previously untreatable malignancies, while limited evidence is available on the management of hepatitis B virus (HBV) in patients undergoing immunotherapy. We systematically reviewed data concerning challenges of hepatic adverse events including HBV reactivation and hepatitis in patients with chronic HBV infection undergoing immunotherapy. METHODS: A systematic search was conducted in Medline, web of science, Embase and Cochrane library up to May 31, 2022. Studies reporting the safety profile of ICIs in patients with HBV infection were eligible. Meta-analyses were conducted to generate odds ratios (ORs) with 95% confidence intervals (CIs). RESULTS: A total of 13 studies including 2561 patients were included for meta-analysis. The overall incidence rates of HBV reactivation in patients with chronic HBV infection and past HBV infection were 1.0% (95% CI 0-3%) and 0% (95% CI 0-0%), respectively. Among patients with chronic HBV infection, the incidence rates of HBV reactivation were 1.0% (95% CI 0-2%) and 10.0% (95% CI 4-18%) for patients with and without antiviral prophylaxis, respectively. Patients with chronic HBV infection were at a higher risk of HBV reactivation compared with those with past HBV infection [OR = 8.69, 95% CI (2.16-34.99)]. Antiviral prophylaxis significantly reduced the risk of HBV reactivation [OR = 0.12, 95% CI (0.02-0.67)] and HBV-associated hepatitis [OR = 0.05, 95% CI (0.01-0.28)] in patients with chronic HBV infection. CONCLUSIONS: Prophylactic antiviral therapy should be administered to patients with chronic HBV infection undergoing anticancer immunotherapy. Patients with past HBV infection are at lower risk of HBV reactivation compared with those with chronic HBV infection, they could be initiated with antiviral prophylaxis or monitored with the intent of on-demand antiviral therapy.

We aim to identify the optimal treatment option of systemic therapy with or without locoregional therapy for advanced hepatocellular carcinoma (HCC). Outcomes of interest include overall survival (OS), progression-free survival (PFS), objective response rate (ORR), grade 3-4 treatment-related adverse events (TRAEs), and incidence of treatment discontinuation due to AEs. The surface under the cumulative ranking curve (SUCRA) probability values were applied to rank the interventions. 23 randomized-controlled trials including 14,303 patients with advanced HCC were included. Lenvatinib plus transcatheter arterial chemoembolization (TACE) ranked best regarding OS benefit (SUCRA: 0.99). Immuno-oncology (IO)-multikinase inhibitor (MKI)/vascular endothelial growth factor (VEGF) inhibitor combinations had a higher probability of providing better OS than IO-IO combinations. IO monotherapies demonstrated superior safety profile while combination therapies caused more toxicity in general. We conclude that combination therapies achieve remarkable efficacy in patients with advanced HCC and clinical decision making requires a careful balance of efficacy versus risk.

Background: Intracellular copper homeostasis requires a complex system. It has shown considerable prospects for intervening in the tumor microenvironment (TME) by regulating copper homeostasis and provoking cuproptosis. Their relationship with hepatocellular carcinoma (HCC) remains elusive. Methods: In TCGA and ICGC datasets, LASSO and multivariate Cox regression were applied to obtain the signature on the basis of genes associated with copper homeostasis and cuproptosis. Bioinformatic tools were utilized to reveal if the signature was correlated with HCC characteristics. Single-cell RNA sequencing data analysis identified differences in tumor and T cells' pathway activity and intercellular communication of immune-related cells. Real-time qPCR analysis was conducted to measure the genes' expression in HCC and adjacent normal tissue from 21 patients. CCK8 assay, scratch assay, transwell, and colony formation were conducted to reveal the effect of genes on in vitro cell proliferation, invasion, migration, and colony formation. Results: We constructed a five-gene scoring system in relation to copper homeostasis and cuproptosis. The high-risk score indicated poor clinical prognosis, enhanced tumor malignancy, and immune-suppressive tumor microenvironment. The T cell activity was markedly reduced in high-risk single-cell samples. The high-risk HCC patients had a better expectation of ICB response and reactivity to anti-PD-1 therapy. A total of 156 drugs were identified as potential signature-related drugs for HCC treatment, and most were sensitive to high-risk patients. Novel ligand-receptor pairs such as FASLG, CCL, CD40, IL2, and IFN-â ¡ signaling pathways were revealed as cellular communication bridges, which may cause differences in TME and immune function. All crucial genes were differentially expressed between HCC and paired adjacent normal tissue. Model-constructed genes affected the phosphorylation of mTOR and AKT in both Huh7 and Hep3B cells. Knockdown of ZCRB1 impaired the proliferation, invasion, migration, and colony formation in HCC cell lines. Conclusion: We obtained a prognostic scoring system to forecast the TME changes and assist in choosing therapy strategies for HCC patients. In this study, we combined copper homeostasis and cuproptosis to show the overall potential risk of copper-related biological processes in HCC for the first time.
RESUMO
Liver metastasis is a frequent phenomenon in advanced tumor disease. Immune checkpoint inhibitors (ICIs) are a new class of therapeutics that can improve the prognosis of cancer patients. The purpose of this study is to elucidate the relationship between liver metastasis and survival outcomes of patients receiving ICIs treatment. We searched four main databases, including PubMed, EMBASE, Cochrane Library, and Web of Science. Overall survival (OS) and progression-free survival (PFS) were the survival outcomes of our concern. Hazard ratio (HR) with 95% confidence interval (CI) were used to evaluate the relationship between liver metastasis and OS/ PFS. Finally, 163 articles were included in the study. The pooled results showed that patients with liver metastasis receiving ICIs treatment had worse OS (HR=1.82, 95%CI:1.59-2.08) and PFS (HR=1.68, 95%CI:1.49-1.89) than patients without liver metastasis. The effect of liver metastasis on ICIs efficacy differed in different tumor types, and patients with urinary system tumors (renal cell carcinoma OS: HR=2.47, 95%CI:1.76-3.45; urothelial carcinoma OS: HR=2.37, 95%CI:2.03-2.76) had the worst prognosis, followed by patients with melanoma (OS: HR=2.04, 95%CI:1.68-2.49) or non-small cell lung cancer (OS: HR=1.81, 95%CI:1.72-1.91). ICIs efficacy in digestive system tumors (colorectal cancer OS: HR=1.35, 95%CI:1.07-1.71; gastric cancer/ esophagogastric cancer OS: HR=1.17, 95%CI:0.90-1.52) was less affected, and peritoneal metastasis and the number of metastases have a greater clinical significance than liver metastasis based on univariate data. For cancer patients receiving ICIs treatment, the occurrence of liver metastasis is associated with poor prognosis. Different cancer types and metastatic sites may hold a different prognostic effect on the efficacy of ICIs treatment in cancer patients.

Aims: This work was designed to identify the subgroup of advanced hepatocellular carcinoma (HCC) patients for whom treatments containing immune checkpoint blockers (ICBs) were most effective. Materials & methods: A meta-analysis was performed to explore the subgroup population with the greatest benefit of treatments containing ICBs. Results: A total of 2228 patients from four randomized control trials were included. Treatments containing ICBs had better overall survival, progression-free survival and higher objective response rate over treatment without ICBs. Subgroup analysis revealed that treatments containing ICBs were highly effective in improving the overall survival of males, patients with macrovascular invasion and/or extrahepatic spread and viral-related HCC patients. Conclusion: Treatments containing ICBs are more effective for males, patients with macrovascular invasion and/or extrahepatic spread and viral-related HCC patients.
Immune checkpoint blockers (ICBs) have significantly improved the prognosis of advanced cancers. However, some patients still cannot benefit from ICBs. The use of ICBs in the treatment of advanced hepatocellular carcinoma (HCC) started late. The subgroup of advanced HCC patients that will benefit most from treatments containing ICBs is still largely unknown. Therefore, a meta-analysis (meta-analysis is a statistical method used to compare or synthesize research results on the same scientific problem) was performed to explore the subgroup population with the greatest benefit of treatments containing ICBs (ICBs alone or in combination with anti-VEGF agents). The results show that treatments containing ICBs are more effective for males, patients with macrovascular invasion and/or extrahepatic spread and viral-related HCC patients.

BACKGROUND: Tenofovir (TDF) and entecavir (ETV) are first-line treatments for patients with chronic hepatitis B virus (HBV) infection. However, the effect of TDF versus ETV on the prognosis of HBV-related hepatocellular carcinoma (HCC) has not been fully clarified yet. RESEARCH DESIGN AND METHODS: PubMed, Embase and Web of science were searched up to March, 2021. Meta-analyses were performed for overall survival (OS), disease-free survival (DFS) and recurrence-free survival (RFS) to assess the effect of TDF versus ETV on the prognosis of HBV-related HCC. RESULTS: A total of 10 studies comprising 4706 Asian patients were included. The pooled results revealed that TDF was associated with better OS (adjusted HR = 0.50, 95% CI: 0.40-0.62; I2 = 36.0%, p = 0.167) and better RFS/DFS (adjusted HR = 0.70, 95% CI: 0.55-0.89, I2 = 71.9%, p = 0.002) than ETV in treatment of HBV-related HCC. Subgroup analysis revealed that OS benefit from TDF was generally consistent, except for patients who underwent non-surgical treatment for HCC. Subgroup analysis also indicated that TDF reduces the risk of late recurrence (HR = 0.41, 95% CI: 0.18-0.0.93; I2 = 63.0%, p = 0.067) rather than early recurrence (HR = 0.99, 95% CI: 0.64-1.52; I2 = 61.3%, p = 0.076). CONCLUSIONS: Compared with ETV, TDF has the advantage of improving OS and reducing late recurrence of patients with HBV-related HCC patients who underwent resection.

Background: The relationship between baseline C-reactive protein (CRP) level and the prognosis of cancer patients receiving immune checkpoint inhibitor (ICI) treatment remains controversial. The aim of this meta-analysis was to clarify whether baseline CRP level can serve as a biomarker to predict the efficiency of ICI therapy. Methods: All associated articles published in the Cochrane Library, EMBASE, and PubMed databases from the inception of the database to December 30, 2021, were retrieved. Progression-free survival (PFS) and overall survival (OS) outcomes were meta-analyzed using the random-effects model and adjusted using the trim-and-fill method because of publication bias. Results: Thirty-three studies (6,124 patients) conducted between 2013 and 2021 were identified. The pooled outcomes implied that high baseline CRP level patients had significantly worse OS (adjusted pooled value for univariate and multivariate analysis outcomes: HR = 1.48, 95% CI = 1.41-1.56; HR = 1.46, 95% CI = 1.34-1.59) and PFS (adjusted pooled value for univariate and multivariate analysis outcomes: HR = 1.29, 95% CI = 1.15-1.45; HR = 1.20, 95% CI = 1.02-1.40) than low baseline CRP level patients, irrespective of cancer or ICI type. Further analysis indicated that 1 mg/dl was appropriate as a cutoff value for determining the low or high level of baseline CRP to predict the OS or PFS of cancer patients receiving ICI treatment (univariate analysis: HR = 1.56, 95% CI = 1.24-1.97, P = 0.909; multivariate analysis: HR = 1.58, 95% CI = 1.23-2.03, P = 0.521). Conclusions: High baseline CRP level (>1 mg/dl) may be an indicator for worse OS and PFS of cancer patients treated with ICIs. More high-quality prospective studies are warranted to assess the predictive value of CRP for ICI treatment.

Objective: This meta-analysis was designed to explore the association between the systemic immune-inflammation index (SII) and the therapeutic effect of immune checkpoint inhibitors. Materials & methods: The authors retrieved relevant studies published before May 25, 2022. Hazard ratio (HR) with 95% CI was used to evaluate the relationship between SII and overall survival (OS) and progression-free survival (PFS). Results: 14 articles comprising 2721 patients were included in this study. The pooled results proved that high SII levels were closely related to poor prognosis in cancer patients receiving immune checkpoint inhibitors (OS HR = 2.40; 95% CI: 2.04-2.82; PFS HR = 1.57; 95% CI: 1.33-1.86) and that an SII value of 750 was appropriate as a cut-off value (OS HR = 2.20; 95% CI: 1.83-2.63; PFS HR = 1.54; 95% CI: 1.33-1.80). Conclusion: High SII levels (>750) may be an indicator of worse OS and PFS in cancer patients treated with immune checkpoint inhibitors.
Immune checkpoint inhibitors (ICIs) have substantially improved the prognosis of many patients with advanced cancer. However, some patients still do not benefit from ICIs. Therefore, determining indicators that can identify patients who may benefit from ICIs is essential. As a noninvasive, convenient and inexpensive clinical indicator, the systemic immuneinflammation index is expected to solve the aforementioned issue. Through this meta-analysis, the authors demonstrated that patients with cancers with high systemic immuneinflammation index levels had shorter survival and a smaller degree of clinical benefit after ICI treatment. Moreover, a systemic immuneinflammation index value of 750 is recommended to be the cut-off value for stratifying patients.

Background: Natural killer (NK) cells play major roles in eliminating tumor cells. Preliminary studies have shown that NK cells and their receptors/ligands have prognostic value in malignant tumors. However, the relevance of NK cells and their receptors/ligands level to the prognosis of hepatocellular carcinoma (HCC) remains unclear. Methods: Several electronic databases were searched from database inception to November 8, 2021. Random effects were introduced to this meta-analysis. The relevance of NK cells and their receptors/ligands level to the prognosis of HCC was evaluated using hazard ratios (HRs) with 95% confidence interval (95%CI). Results: 26 studies were included in the analysis. The pooled results showed that high NK cells levels were associated with better overall survival (HR=0.70, 95%CI 0.57-0.86, P=0.001) and disease-free survival (HR=0.61, 95%CI 0.40-0.93, P=0.022) of HCC patients. In subgroup analysis for overall survival, CD57+ NK cells (HR=0.70, 95%CI 0.55-0.89, P=0.004) had better prognostic value over CD56+ NK cells (HR=0.69, 95%CI 0.38-1.25, P=0.224), and intratumor NK cells had better prognostic value (HR=0.71, 95%CI 0.55-0.90, P=0.005) over peripheral NK cells (HR=0.66, 95%CI 0.41-1.06, P=0.088). In addition, high level of NK cell inhibitory receptors predicted increased recurrence of HCC, while the prognostic role of NK cell activating receptors remained unclear. Conclusion: NK cells and their inhibitory receptors have prognostic value for HCC. The prognostic role of NK cell activating receptors is unclear and more high-quality prospective studies are essential to evaluate the prognostic value of NK cells and their receptors/ligands for HCC.
