RESUMO
AIM: Cabozantinib showed a favorable benefit-risk profile in Japanese patients with advanced hepatocellular carcinoma (HCC) in an open-label, phase II study (NCT03586973). This analysis presents cumulative data to final database lock. METHODS: Patients with previously treated, advanced HCC received cabozantinib 60 mg/day. Progression-free survival (PFS) and tumor response rates in prior-sorafenib and sorafenib-naïve cohorts were assessed by independent radiology committee (IRC) and an investigator. Liver function was evaluated by albumin-bilirubin (ALBI) score. RESULTS: Median cabozantinib exposure was 5.6 months. In the prior-sorafenib cohort (n = 20), median PFS was 7.4 months per IRC assessment and 5.6 months per investigator assessment. In the sorafenib-naïve cohort (n = 14), median PFS was 3.6 and 4.4 months per IRC and investigator assessment, respectively. Six-month PFS rate per IRC and investigator assessment in the prior-sorafenib cohort was 59.8% and 49.5%, respectively, and in the sorafenib-naïve cohort was 16.7% and 35.7%, respectively. Disease control rate by both IRC and investigator assessment was 85.0% in the prior-sorafenib cohort and 64.3% in the sorafenib-naïve cohort. Median overall survival (Kaplan-Meier estimate) was 19.3 and 9.9 months in the prior-sorafenib and sorafenib-naïve cohort, respectively. Mean ALBI score remained relatively constant in patients able to continue treatment. The most frequent adverse events were palmar-plantar erythrodysesthesia syndrome, diarrhea, hypertension, and decreased appetite. No new safety concerns were identified. CONCLUSIONS: Cabozantinib showed efficacy and a manageable safety profile in Japanese patients with advanced HCC.
RESUMO
Direct-acting antivirals (DAAs) have recently been developed to treat hepatitis C virus (HCV) infection, and interferon-free DAA treatment has improved liver function of HCV patients. The risk of hepatocellular carcinoma (HCC) occurrence following HCV eradication has been previously reported, but HCC may have been missed following imaging diagnosis before DAA administration in previous studies. Therefore, the present study aimed to identify definite predictors of HCC occurrence ≥1 year after DAA treatment. Among 956 patients receiving DAAs for HCV infection, 567 patients who achieved sustained virologic response with no history of HCC treatment were enrolled in this study between September 2014 and July 2021. The incidence of HCC in HCV-infected patients ≥1 year following DAA treatment, and the predictors contributing to HCC occurrence were identified using clinical characteristics and blood test results. In the present study, 25 patients developed HCC. The incidence of HCC was 1.4%, 3.2%, 4.9% and 6.8% at 2, 3, 4 and 5 years, respectively, from the end of treatment with DAAs. Multivariate logistic analysis revealed serum α-fetoprotein level at end of treatment (EOT-AFP) >3.8 ng/ml ≥1 year following treatment with DAAs (HR, 9.7; p < .0001) as an independent factor that may contribute to HCC occurrence following DAA treatment. In conclusion, serum EOT-AFP level may serve an important role in determining the risk of HCC occurrence ≥1 year after DAA treatment. Regular examinations are required even if serum EOT-AFP level is low at treatment completion.

The risk of hepatocellular carcinoma (HCC) occurrence following hepatitis C virus (HCV) eradication has been previously reported, but the impact of HCV eradication on advanced HCC patient survival remains unclear. Therefore, the present study aimed to evaluate the effect of HCV eradication on the survival outcome of patients with advanced HCC treated with sorafenib. One hundred and three HCV-related advanced HCC patients who were treated with sorafenib were enrolled in this study. Of these, 43 patients were administered antiviral therapy before sorafenib treatment (HCV eradication group), while 60 patients remained HCV-infected (HCV non-eradication group). We analysed the impact of HCV eradication on survival in advanced HCC treated with sorafenib. Median overall survival (OS) was significantly longer in the HCV eradication group than in the HCV non-eradication group (24.0 months vs. 14.1 months; p = 0.001). Although there was no significant difference in the albumin-bilirubin (ALBI) score at the start of treatment between the HCV eradication group and the non-eradication group (p = 0.065), the ALBI score at 2 months after initiation of sorafenib treatment was significantly decreased in the HCV non-eradication group (p < 0.001), but not in the HCV eradication group (p = 0.121). Multivariate logistic analysis revealed HCV eradication (hazard ratio [HR], 0.5; p = 0.006) and ALBI score at the start of treatment (HR, 2.47; p = 0.002) as factors that may contribute to OS. HCV eradication may serve an important role in the survival outcome of advanced HCC patients treated with sorafenib.

A 61-year-old man was admitted due to alcoholic liver cirrhosis, portal vein thrombosis, hepatocellular carcinoma, and chronic pancreatitis. The patient's portal vein thrombosis improved with anticoagulant therapy. Serum amylase gradually increased, but there was no abdominal pain. The patient was placed under observation. The pain in both ankle and knee joints appeared on nine days after admission. Multiple osteonecrotic lesions of both elbows, both knees and both ankle joints were examined using 99mTc bone scintigraphic examinations. Magnetic resonance of the right ankle joint showed osteonecrosis. The pain of the right ankle joint improved with a decrease of serum amylase. We report that this is a rare case of multiple osteonecrosis caused by exacerbation of chronic pancreatitis.

BACKGROUND: Post hoc analyses assessed the prognostic and predictive value of baseline alpha-fetoprotein (AFP), as well as clinical outcomes by AFP response or progression, during treatment in two placebo-controlled trials (REACH, REACH-2). METHODS: Serum AFP was measured at baseline and every three cycles. The prognostic and predictive value of baseline AFP was assessed by Cox regression models and Subpopulation Treatment Effect Pattern Plot method. Associations between AFP (≥ 20% increase) and radiographic progression and efficacy were assessed. RESULTS: Baseline AFP was confirmed as a continuous (REACH, REACH-2; p < 0.0001) and dichotomous (≥400 vs. <400 ng/ml; REACH, p < 0.01) prognostic factor, and was predictive for ramucirumab survival benefit in REACH (p = 0.0042 continuous; p < 0.0001 dichotomous). Time to AFP (hazard ratio [HR] 0.513; p < 0.0001) and radiographic (HR 0.549; p < 0.0001) progression favoured ramucirumab. Association between AFP and radiographic progression was shown for up to 6 (odds ratio [OR] 5.1; p < 0.0001) and 6-12 weeks (OR 1.8; p = 0.0065). AFP response was higher with ramucirumab vs. placebo (p < 0.0001). Survival was longer in patients with an AFP response than patients without (13.6 vs. 5.6 months, HR 0.451; 95% confidence interval, 0.354-0.574; p < 0.0001). CONCLUSIONS: AFP is an important prognostic factor and a predictive biomarker for ramucirumab survival benefit. AFP ≥ 400 ng/ml is an appropriate selection criterion for ramucirumab. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov, REACH (NCT01140347) and REACH-2 (NCT02435433).

An 80-year-old woman was treated with pembrolizumab for non-small cell lung carcinoma. The hepatobiliary enzymes of the patient were elevated before the start of the ninth treatment cycle. The patient was diagnosed with pembrolizumab-induced sclerosing cholangitis based on magnetic resonance cholangiopancreatography and liver biopsy. Liver dysfunction improved with steroid therapy, and hepatobiliary enzymes increased again. The patient was treated with methylprednisolone (1000mg/day for 3 days) followed by oral prednisolone (1mg/kg/day). The patient's hepatobiliary enzymes subsequently decreased, and the oral prednisolone was tapered. Another liver biopsy, which showed a decrease in the hepatic CD8+ T cell count, was performed. Liver dysfunction did not recur although steroid therapy was discontinued after 1 year of administration.

A previous randomized phase 2 study of hepatocellular carcinoma revealed that the c-Met inhibitor tivantinib as second-line treatment significantly prolonged progression-free survival in a subpopulation whose tumor samples highly expressed c-Met (MET-high). Accordingly, this phase 3 study was conducted to evaluate the efficacy of tivantinib as a second-line treatment for Japanese patients with MET-high hepatocellular carcinoma. This randomized, double-blind, placebo-controlled study was conducted at 60 centers in Japan. Hepatocellular carcinoma patients with one prior sorafenib treatment and those with MET-high tumor samples were eligible for inclusion. Registered patients were randomly assigned to either the tivantinib or placebo group at a 2:1 ratio and were treated with twice-a-day oral tivantinib (120 mg bid) or placebo until the discontinuation criteria were met. The primary endpoint was progression-free survival while the secondary endpoints included overall survival and safety. Between January 2014 and June 2016, 386 patients provided consent, and 195 patients were randomized to the tivantinib (n = 134) or placebo (n = 61) group. Median progression-free survival was 2.8 (95% confidence interval: 2.7-2.9) and 2.3 (1.5-2.8) mo in the tivantinib and placebo groups, respectively (hazard ratio = 0.74, 95% confidence interval: 0.52-1.04, P = .082). Median overall survival was 10.3 (95% confidence interval: 8.1-11.6) and 8.5 (6.2-11.4) mo in the tivantinib and placebo group, respectively (hazard ratio = 0.82, 95% confidence interval: 0.58-1.15). The most common tivantinib-related grade ≥3 adverse events were neutropenia (31.6%), leukocytopenia (24.8%), and anemia (12.0%). This study did not confirm the significant efficacy of tivantinib as a second-line treatment for Japanese patients with MET-high hepatocellular carcinoma. (NCT02029157).

BACKGROUND & AIMS: Limited data on treatment of elderly patients with hepatocellular carcinoma (HCC) increase the unmet need. REACH and REACH-2 were global phase III studies of ramucirumab in patients with HCC after prior sorafenib, where patients with alpha-fetoprotein (AFP) ≥400 ng/mL showed an overall ssurvival (OS) benefit for ramucirumab. These post-hoc analyses examined efficacy and safety of ramucirumab in patients with HCC and baseline AFP ≥ 400 ng/mL by three prespecified age subgroups (<65, ≥65 to <75 and ≥75 years). METHODS: Individual patient data were pooled from REACH (baseline AFP ≥400 ng/mL) and REACH-2. Kaplan-Meier and Cox proportional hazards regression methods (stratified by study) assessed OS, progression-free survival (PFS), time to progression (TTP) and patient-reported outcomes (Functional Hepatobiliary System Index-8 [FHSI-8] score). RESULTS: A total of 542 patients (<65 years: n = 302; ≥65 to <75 years: n = 160; ≥75 years: n = 80) showed similar baseline characteristics between ramucirumab and placebo. Older subgroups had higher hepatitis C and steatohepatitis incidences, and lower AFP levels, than the <65 years subgroup. Ramucirumab prolonged OS in patients <65 years (hazard ratio [HR], 0.753; 95% CI 0.581-0.975), ≥65 to <75 years (0.602; 0.419-0.866) and ≥75 years (0.709; 0.420-1.199), PFS and TTP irrespective of age. Ramucirumab showed similar overall safety profiles across subgroups, with a consistent median relative dose intensity ≥97.8%. A trend towards a delay in symptom deterioration in FHSI-8 with ramucirumab was observed in all subgroups. CONCLUSIONS: In this post-hoc analysis, ramucirumab showed a survival benefit across age subgroups with a tolerable safety profile, supporting its use in advanced HCC with elevated AFP, irrespective of age, including ≥75 years.

A 49-year-old man with chronic hepatitis B receiving treatment with entecavir visited a hospital with a complaint of abdominal pain. Computed tomography (CT) showed 2 liver tumors, each measuring 1cm in diameter, 1 in segment 7 and 1 in segment 4. Magnetic resonance imaging (MRI) showed a hypervascular tumor in segment 7 that appeared in a site different from that seen on CT. The liver tumor in segment 4 was not detected by MRI. Two months later, MRI showed a new liver tumor in segment 7/6 and that the liver tumor in segment 7 had increased to 2cm in diameter;blood tests showed eosinophilia. Enzyme-linked immunosorbent assay showed a high serum Toxocara antibody. The patient was diagnosed as having hepatic toxocariasis and was treated with albendazole for 8 weeks. After treatment, MRI showed that the liver tumors disappeared. Eosinophilia, multiple lesions, and the disappearance of the tumors were characteristic findings of visceral larva migrans.

BACKGROUND: Patients with advanced hepatocellular carcinoma and increased α-fetoprotein concentrations have poor prognosis. We aimed to establish the efficacy of ramucirumab in patients with advanced hepatocellular carcinoma and α-fetoprotein concentrations of 400 ng/mL or higher. METHODS: REACH-2 was a randomised, double-blind, placebo-controlled, phase 3 trial done at 92 hospitals, clinics, and medical centres in 20 countries. Eligible patients were aged 18 years or older and had histologically or cytologically confirmed hepatocellular carcinoma, or diagnosed cirrhosis and hepatocellular carcinoma, Barcelona Clinic Liver Cancer stage B or C disease, Child-Pugh class A liver disease, Eastern Cooperative Oncology Group (ECOG) performance statuses of 0 or 1, α-fetoprotein concentrations of 400 ng/mL or greater, and had previously received first-line sorafenib. Participants were randomly assigned (2:1) via an interactive web response system with a computer-generated random sequence to 8 mg/kg intravenous ramucirumab every 2 weeks or placebo. All patients received best supportive care. The primary endpoint was overall survival. Secondary endpoints were progression-free survival, proportion of patients achieving an objective response, time to radiographic progression, safety, time to deterioration in scores on the Functional Assessment of Cancer Therapy Hepatobiliary Symptom Index 8 (FHSI-8), and time to deterioration in ECOG performance status. We also pooled individual patient data from REACH-2 with data from REACH (NCT01140347) for patients with α-fetoprotein concentrations of 400 ng/mL or greater. Efficacy analyses were by intention to treat, whereas safety analyses were done in all patients who received at least one dose of study drug. This trial is registered with ClinicalTrials.gov, number NCT02435433. FINDINGS: Between July 26, 2015, and Aug 30, 2017, 292 patients were randomly assigned, 197 to the ramucirumab group and 95 to the placebo group. At a median follow-up of 7·6 months (IQR 4·0-12·5), median overall survival (8·5 months [95% CI 7·0-10·6] vs 7·3 months [5·4-9·1]; hazard ratio [HR] 0·710 [95% CI 0·531-0·949]; p=0·0199) and progression-free survival (2·8 months [2·8-4·1] vs 1·6 months [1·5-2·7]; 0·452 [0·339-0·603]; p<0·0001) were significantly improved in the ramucirumab group compared with the placebo group. The proportion of patients with an objective response did not differ significantly between groups (nine [5%] of 197 vs one [1%] of 95; p=0·1697). Median time to deterioration in FHSI-8 total scores (3·7 months [95% CI 2·8-4·4] vs 2·8 months [1·6-2·9]; HR 0·799 [95% CI 0·545-1·171]; p=0·238) and ECOG performance statuses (HR 1·082 [95% CI 0·639-1·832]; p=0·77) did not differ between groups. Grade 3 or worse treatment-emergent adverse events that occurred in at least 5% of patients in either group were hypertension (25 [13%] in the ramucirumab group vs five [5%] in the placebo group), hyponatraemia (11 [6%] vs 0) and increased aspartate aminotransferase (six [3%] vs five [5%]). Serious adverse events of any grade and cause occurred in 68 (35%) patients in the ramucirumab group and 28 (29%) patients in the placebo group. Three patients in the ramucirumab group died from treatment-emergent adverse events that were judged to be related to study treatment (one had acute kidney injury, one had hepatorenal syndrome, and one had renal failure). INTERPRETATION: REACH-2 met its primary endpoint, showing improved overall survival for ramucirumab compared with placebo in patients with hepatocellular carcinoma and α-fetoprotein concentrations of at least 400 ng/mL who had previously received sorafenib. Ramucirumab was well tolerated, with a manageable safety profile. To our knowledge, REACH-2 is the first positive phase 3 trial done in a biomarker-selected patient population with hepatocellular carcinoma. FUNDING: Eli Lilly.

The global coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has affected millions of lives, leading to significant morbidity and mortality. With >772 million cases and nearly seven million deaths reported worldwide to date, the development of vaccines has been a critical step in mitigating the impact of COVID-19. However, concerns have arisen regarding the potential for SARS-CoV-2 mRNA vaccination to trigger autoimmune diseases, including autoimmune hepatitis (AIH). The present single-center, retrospective study aimed to compare the clinical and pathological features of AIH in patients with or without a history of SARS-CoV-2 mRNA vaccination. A total of 72 patients with AIH were examined. Among them, 10 had received the SARS-CoV-2 mRNA vaccination prior to AIH onset. These patients exhibited more pronounced CD4+ T cell infiltration into the liver tissue compared with those who were unvaccinated. No significant differences in the levels of other liver enzymes, autoimmune antibodies, or CD8+ T cell infiltration were observed between the groups. Moreover, the AIH patients with a history of SARS-CoV-2 mRNA vaccination had more extensive CD4+ T cell infiltration in their liver tissues than the unvaccinated patients. These findings suggested that the immune response to SARS-CoV-2 mRNA vaccination may influence the pathogenesis of AIH, highlighting the need for further research into the relationship between SARS-CoV-2 mRNA vaccination and autoimmune liver diseases. Such studies will also help clarify the distinction between vaccine-induced liver injury and traditional AIH.
RESUMO
BACKGROUND/AIM: The landscape of treatments for hepatocellular carcinoma (HCC), including immune checkpoint inhibitors, has expanded significantly. However, unresectable HCC patients with portal vein tumor thrombus (PVTT) continue to face a poor prognosis. This investigation examined the survival outcomes and determinants influencing survival rates in advanced HCC patients with PVTT undergoing treatment with atezolizumab plus bevacizumab (ATZ+BEV) or hepatic arterial infusion chemotherapy (HAIC). PATIENTS AND METHODS: Between December 2003 and June 2023, 48 advanced HCC with PVTT underwent treatment with either ATZ+BEV (16 patients) or HAIC (32 patients). RESULTS: The analysis revealed no significant disparities in overall survival (OS) or treatment efficacy between the ATZ+BEV and HAIC groups (ATZ+BEV: 10.0 months, HAIC: 15.3 months). Treatment with either ATZ+BEV or HAIC resulted in minimal alterations in the ALBI score and preserved hepatic function. Independent prognostic factors for OS, identified via multivariate logistic regression, included serum α-fetoprotein levels >400 ng/ml [hazard ratio (HR)=1.94; p=0.001], the existence of more than five tumors (HR=1.55; p=0.043), and the Child-Pugh score (HR=2.53; p=0.002). CONCLUSION: This investigation revealed no significant variance in OS and response rates between patients receiving ATZ+BEV and those treated with HAIC. The survival of advanced HCC patients with PVTT is intricately linked to the preservation of liver function, emphasizing the necessity for additional research to enhance treatment approaches for this patient population.

Lenvatinib is an approved therapy for advanced hepatocellular carcinoma (HCC). Recently, immune checkpoint inhibitors have been approved as frontline chemotherapies for HCC, and the tumor immune microenvironment (TIME) has been demonstrated to significantly affect HCC treatment. The neutrophil-to-lymphocyte ratio (NLR) is associated with the TIME, and the dynamics of the NLR are associated with prognosis or treatment efficacy in various cancer types. The present study investigated the dynamics of the TIME using the NLR in 101 patients with HCC treated with lenvatinib. Immunostaining for CD8+ tumor-infiltrating lymphocytes (TILs) was also performed in 9 patients who underwent liver tumor biopsy prior to subsequent chemotherapy for progression or discontinuation due to adverse events on lenvatinib treatment. The NLR values measured at the start of treatment (SOT), after 1 month of treatment and after 3 months of treatment were 2.78±2.20, 2.61±1.86 and 2.66±2.36, respectively (P=0.733). Among the patients with no reduction in the initial dose, there was no significant difference between the NLR after 1 month (2.34±0.25) and that at the SOT (2.86±2.33) (P=0.613). In patients who achieved a complete or partial response, the NLR at the time of the best tumor response was 1.65±0.56, which was significantly lower than that at the SOT (2.05±0.78) (P=0.023). In patients who did not respond to lenvatinib, the NLR at the time of disease progression was 3.68±3.19, which was significantly higher than that at the SOT (2.78±1.79) (P=0.043). Overall, 5 out of the 6 patients who did not respond to lenvatinib had low CD8+ TIL counts at disease progression. Although the present study included a limited number of patients, the NLR was associated with the therapeutic effects of lenvatinib. These findings suggest the potential of lenvatinib as an immunomodulator.
RESUMO
Background/Aim: Atezolizumab in combination with bevacizumab is an approved systemic chemotherapy regimen for advanced hepatocellular carcinoma (HCC). However, immune checkpoint inhibitors (ICIs), such as atezolizumab, frequently lead to immune-related adverse events (irAEs). The identification of biomarkers that can predict the occurrence of irAEs is crucial for the optimal management of patients undergoing ICI treatment. Patients and Methods: Between October 2020 and June 2023, we conducted a study involving 69 patients with advanced HCC who received treatment with atezolizumab plus bevacizumab. We conducted an analysis of blood-based biomarkers to identify independent risk factors associated with irAEs. Results: In our study, 12 out of 69 patients (17.4%) experienced irAEs. Our investigation into blood-based biomarkers revealed that a neutrophil-to-lymphocyte ratio (NLR) <2.04 at three weeks after the initiation of treatment had high predictive power (area under the curve: 0.77) for irAEs. Furthermore, multivariate logistic analysis identified NLR at three weeks (hazard ratio=0.23; p=0.037) and non-viral infection (hazard ratio=4.47; p=0.037) as independent factors contributing to the occurrence of irAEs. Patients who developed irAEs demonstrated a more favorable overall response rate (75.0% vs. 28.1%, p=0.005), disease control rate (91.6% vs. 52.6%, p=0.016), and progression-free survival (12.1 months vs. 6.0 months, p=0.010) than those who did not experience irAEs. Conclusion: An NLR <2.04 at three weeks after the initiation of treatment may serve as a valuable biomarker for predicting irAEs in patients with HCC undergoing atezolizumab plus bevacizumab therapy.
RESUMO
Background/Aim: Numerous agents, including immune checkpoint inhibitors, are now available for hepatocellular carcinoma (HCC) treatment. Most trials involving systemic chemotherapy have included patients with Child-Pugh class A, while excluding or minimally enrolling those with Child-Pugh class B, due to liver dysfunction-related mortality. This study aimed to identify prognostic factors for survival in Child-Pugh class B patients receiving sorafenib (SOR), lenvatinib (LEN), atezolizumab plus bevacizumab (ATZ+BEV), or hepatic arterial infusion chemotherapy (HAIC). Patients and Methods: From December 2003 to June 2023, 137 patients with advanced HCC receiving systemic chemotherapies (SOR: n=43, LEN: n=16, ATZ+BEV: n=18, HAIC: n=60) were enrolled. Results: Overall survival (OS) and response rates did not differ significantly across treatments (SOR: 8.3 months, LEN: 10.2 months, ATZ+BEV: 8.5 months, HAIC: 7.3 months). Patients on HAIC and LEN had a lower rate of discontinuing treatment within three months compared to those on ATZ+BEV and SOR. HAIC was associated with fewer changes in ALBI score and better preservation of liver function. Multivariate logistic regression identified serum α-fetoprotein >400 ng/ml [hazard ratio (HR)=1.94; p=0.001], tumor count >5 (HR=1.55; p=0.043), and Child-Pugh score (HR=2.53; p=0.002) as independent predictors of OS. Conclusion: OS and response rates were similar across systemic chemotherapies. Prognosis for HCC in Child-Pugh class B patients was associated with liver function, necessitating further research for optimal treatment.
RESUMO
Background and Aim: Direct-acting antivirals (DAAs) have recently been developed to treat hepatitis C virus (HCV) infection. Additionally, interferon-free DAA treatment has improved liver function and reduced the risk of hepatocellular carcinoma (HCC) following HCV eradication. Previous studies on HCV have focused mainly on the treatment rate and the risk of developing HCC, and less attention has been given to loss to follow-up (LTFU) after DAA treatment. Therefore, the present study aimed to identify the definitive risk factors for LTFU after the start of DAA treatment. Methods: Between September 2017 and March 2022, 296 patients receiving glecaprevir and pibrentasvir for HCV infection were enrolled in this study. The incidence of LTFU following DAA treatment and the risk factors contributing to LTFU were identified using the patients' clinical characteristics. Results: In the present study, 75 patients (25.3%) interrupted their follow-up visits. Multivariate logistic analysis revealed a history of injection drug use (hazard ratio [HR], 1.81; P = 0.017), treatment duration (8 weeks) (HR, 3.51; P = 0.0033), and age <70 years (HR, 1.9; P = 0.0422) as independent factors associated with LTFU after the start of DAA treatment. Conclusion: Young patients and those with injection drug use are likely to discontinue their follow-up visits after the start of DAA treatment for HCV infection. Therefore, these patients require strict supervision.
RESUMO
Background/Aim: In radiofrequency ablation (RFA) treatment of hepatocellular carcinoma (HCC), the therapeutic effect depends on the appropriate position of the electrode. To improve the accuracy of the electrode needle position, we currently perform RFA with combined ultrasound sonography (US) and computed tomography (CT) guidance. The purpose of this study was to evaluate the effectiveness of this US/CT-guided RFA method. Patients and Methods: This retrospective study recruited 97 patients with single tumors treated with transcatheter arterial chemoembolization and monopolar RFA between January 2013 and December 2017. Among these, 50 patients were treated with RFA under US/CT guidance (US/CT-guided group) and 47 were treated with RFA under US guidance alone (US-guided group). We analyzed the efficacy of US/CT guidance compared with US guidance alone. Results: The 1-, 2-, and 3-year local recurrence rates for the US/CT-guided and US-guided groups were 4.1%, 6.3%, and 8.6%, and 19.6%, 31.6%, and 41.9%, respectively. The local recurrence rate was lower in the US/CT-guided group (p=0.0030). Cox proportional hazards model for multivariate analysis demonstrated that the independent risk factors associated with local recurrence were tumor size (p=0.0028) and US/CT guidance (p=0.0037). Conclusion: US/CT-guided RFA for HCC reduced the local recurrence rate compared with US-guided RFA alone.
RESUMO
In the systemic drug treatment of hepatocellular carcinoma, only the tyrosine kinase inhibitor (TKI) sorafenib was available for a period. This was followed by the development of regorafenib as a second-line treatment after sorafenib, and then lenvatinib, a new TKI, proved non-inferiority to sorafenib and became available as a first-line treatment. Subsequently, cabozantinib, another TKI, was introduced as a second-line treatment, along with ramucirumab, the only drug proven to be predictive of therapeutic efficacy when AFP levels are >400 ng/mL. It is an anti-VEGF receptor antibody. More recently, immune checkpoint inhibitors have become the mainstay of systemic therapy and can now be used as a first-line standard treatment for HCC. However, the objective response rate for these drugs is currently only 30% to 40%, and there is a high incidence of side effects. Additionally, there are no practical biomarkers to predict their therapeutic effects. Therefore, this review provides an overview of extensive research conducted on potential HCC biomarkers from blood, tissue, or imaging information that can be used in practice to predict the therapeutic efficacy of systemic therapy before its initiation.
RESUMO
BACKGROUND/AIM: Systemic chemotherapy with atezolizumab plus bevacizumab is approved for unresectable hepatocellular carcinoma (HCC). It is necessary to identify probable predictive biomarkers for chemotherapies. HCC with rim arterial-phase enhancement (APHE) has been linked to aggressive tumor activity. PATIENTS AND METHODS: We studied the efficacy of atezolizumab plus bevacizumab for HCC using computed tomography (CT) or magnetic resonance imaging (MRI) imaging features. In total, 51 HCC patients who underwent CT or MRI were classified by the feature of rim APHE. RESULTS: Clinical responses to chemotherapy were evaluated, and among those who received atezolizumab plus bevacizumab, there were 10 (19.6%) patients with rim APHE and 41 (80.4%) patients without rim APHE. We found that patients with rim APHE had a better response than those without rim APHE, and patients with rim APHE had longer median progression-free survival compared with those without rim APHE (p=0.026). Furthermore, liver tumor biopsy showed that HCC with rim APHE had a higher proportion of CD8+ tumor-infiltrating lymphocytes (p<0.01). CONCLUSION: Rim APHE in CT/MRI imaging might be a noninvasive biomarker for predicting response to atezolizumab plus bevacizumab.
RESUMO
Atezolizumab plus bevacizumab and lenvatinib are approved frontline therapies for advanced hepatocellular carcinoma (HCC). Patients with advanced HCC continue to have a poor prognosis despite these therapeutic choices. Previous studies have reported CD8+ tumor-infiltrating lymphocytes (TILs) as a biomarker to predict responsiveness to systemic chemotherapy. The present study investigated whether evaluating CD8+ TILs by immunohistochemistry staining of liver tumor biopsy tissues could help predict the response of patients with HCC to atezolizumab plus bevacizumab and lenvatinib. In total, 39 patients with HCC who underwent liver tumor biopsy were classified into high and low CD8+ TILs groups and were then divided by therapy type. The clinical responses to treatment in both groups were evaluated for each therapy. There were 12 patients with high-level CD8+ TILs and 12 patients with low-level CD8+ TILs among those who received atezolizumab plus bevacizumab. An improved response rate was observed in the high-level group compared with the low-level group. The high-level CD8+ TILs group had a significantly longer median progression-free survival compared with the low-level group. Among the patients with HCC who received lenvatinib, five had high-level CD8+ TILs and 10 had low-level CD8+ TILs. There were no differences in response rate or progression-free survival between these groups. Although the present study included only a limited number of patients, the findings suggested that CD8+ TILs could be a biomarker for predicting response to systemic chemotherapy in HCC.
