RESUMEN
BACKGROUND & AIMS: Oral antiviral therapy with nucleos(t)ide analogues (NAs) for chronic hepatitis B (CHB) is well-tolerated and lifesaving, but real-world data on utilization are limited. We examined rates of evaluation and treatment in patients from the REAL-B consortium. METHODS: This was a cross-sectional study nested within our retrospective multinational clinical consortium (2000-2021). We determined the proportions of patients receiving adequate evaluation, meeting AASLD treatment criteria, and initiating treatment at any time during the study period. We also identified factors associated with receiving adequate evaluation and treatment using multivariable logistic regression analyses. RESULTS: We analyzed 12,566 adult treatment-naïve patients with CHB from 25 centers in 9 countries (mean age 47.1 years, 41.7% female, 96.1% Asian, 49.6% Western region, 8.7% cirrhosis). Overall, 73.3% (9,206 patients) received adequate evaluation. Among the adequately evaluated, 32.6% (3,001 patients) were treatment eligible by AASLD criteria, 83.3% (2,500 patients) of whom were initiated on NAs, with consistent findings in analyses using EASL criteria. On multivariable logistic regression adjusting for age, sex, cirrhosis, and ethnicity plus region, female sex was associated with adequate evaluation (adjusted odds ratio [aOR] 1.13, p = 0.004), but female treatment-eligible patients were about 50% less likely to initiate NAs (aOR 0.54, p <0.001). Additionally, the lowest evaluation and treatment rates were among Asian patients from the West, but no difference was observed between non-Asian patients and Asian patients from the East. Asian patients from the West (vs. East) were about 40-50% less likely to undergo adequate evaluation (aOR 0.60) and initiate NAs (aOR 0.54) (both p <0.001). CONCLUSIONS: Evaluation and treatment rates were suboptimal for patients with CHB in both the East and West, with significant sex and ethnic disparities. Improved linkage to care with linguistically competent and culturally sensitive approaches is needed. IMPACT AND IMPLICATIONS: Significant sex and ethnic disparities exist in hepatitis B evaluation and treatment, with female treatment-eligible patients about 50% less likely to receive antiviral treatment and Asian patients from Western regions also about 50% less likely to receive adequate evaluation or treatment compared to Asians from the East (there was no significant difference between Asian patients from the East and non-Asian patients). Improved linkage to care with linguistically competent and culturally sensitive approaches is needed.

BACKGROUND AND AIMS: HCC risk in chronic hepatitis B (CHB) is higher in the indeterminate phase compared with the inactive phase. However, it is unclear if antiviral therapy reduces HCC risk in this population. We aimed to evaluate the association between antiviral therapy and HCC risk in the indeterminate phase. APPROACH AND RESULTS: We analyzed 855 adult (59% male), treatment-naïve patients with CHB infection without advanced fibrosis in the indeterminate phase at 14 centers (USA, Europe, and Asia). Inverse probability of treatment weighting (IPTW) was used to balance the treated (n = 405) and untreated (n = 450) groups. The primary outcome was HCC development. The mean age was 46±13 years, the median alanine transaminase was 38 (interquartile range, 24-52) U/L, the mean HBV DNA was 4.5±2.1 log 10 IU/mL, and 20% were HBeAg positive. The 2 groups were similar after IPTW. After IPTW (n = 819), the 5-, 10-, and 15-year cumulative HCC incidence was 3%, 4%, and 9% among treated patients (n = 394) versus 3%, 15%, and 19%, among untreated patients (n = 425), respectively ( p = 0.02), with consistent findings in subgroup analyses for age >35 years, males, HBeAg positive, HBV DNA>1000 IU/mL, and alanine transaminaseAsunto(s)

RESUMEN
This study aimed to complement the results of the REACH-2 study by prospectively evaluating the safety and efficacy of ramucirumab in advanced hepatocellular carcinoma (HCC) in a real-world setting. This was an open-label, nonrandomized, multicenter, prospective study conducted at 13 institutions in Japan (jRCTs031190236). The study included Child-Pugh Class A patients with advanced HCC who had received pretreatment with atezolizumab plus bevacizumab (Atez/Bev) or lenvatinib. Ramucirumab was introduced as a second-line treatment after Atez/Bev or lenvatinib and as a third-line treatment after Atez/Bev and lenvatinib. Between May 2020 and July 2022, we enrolled 19 patients, including 17 who received ramucirumab. Additionally, seven patients received lenvatinib, another seven patients received Atez/Bev, and three patients received Atez/Bev followed by lenvatinib as prior treatment. The primary endpoint was a 6-month progression-free survival (PFS) rate, which was 14.3%. The median PFS and overall survival were 3.7 and 12.0 months, respectively. The most common grade ≥ 3 adverse events (AEs) were hypertension (23.5%), proteinuria (17.6%), and neutropenia (11.8%). The discontinuation rate due to AEs was 29.4%. Six patients progressed from Child-Pugh A to B after treatment with ramucirumab. Thirteen patients were eligible for post-ramucirumab treatment, including systemic therapy. Despite the limited number of patients, the efficacy of ramucirumab was comparable to that observed in the REACH-2 study when used after lenvatinib and Atez/Bev. However, the incidence of AEs was higher than that in the REACH-2 study.

BACKGROUND & AIMS: The study goal was to compare the outcomes of patients with intermediate-stage (Barcelona Clinic Liver Cancer [BCLC]-B) hepatocellular carcinoma (HCC) who received atezolizumab plus bevacizumab (Atezo/Bev) or lenvatinib (LEN) as first-line systemic therapy. METHODS: A total of 358 patients with BCLC-B HCC treated with Atezo/Bev (n = 177) or LEN (n = 181) as first-line systemic therapy were included. RESULTS: The median progression-free survival (PFS) times in the Atezo/Bev and LEN groups were 10.8 months (95% confidence interval [CI], 7.8-12.6) and 7.3 months (95% CI, 6.3-8.5), respectively (p = .019). In the propensity score-matched cohort, the median PFS times in the Atezo/Bev (n = 151) and LEN (n = 151) groups were 10.2 months (95% CI, 7.0-12.3) and 6.9 months (95% CI, 5.9-8.1), respectively (p = .020). Restricted mean survival times of PFS were significantly higher in the Atezo/Bev group than in the LEN group at landmarks of 12 and 18 months (p = .031 and .012, respectively). In a subgroup analysis of patients with HCC beyond the up-to-seven criteria, the median PFS times in the Atezo/Bev (n = 134) and LEN (n = 117) groups were 10.5 months (95% CI, 7.0-11.8) and 6.3 months (95% CI, 5.5-7.3), respectively (p = .044). CONCLUSIONS: The use of Atezo/Bev as first-line systemic therapy in patients with BCLC-B HCC is expected to result in good PFS.

AIM: An association between hepatitis B core-related antigen (HBcrAg) kinetics and hepatocarcinogenesis during nucleoside (t)id analog (NA) treatment has recently been reported. HBcrAg kinetics and factors associated with HBcrAg response during tenofovir alafenamide (TAF) administration remain unclear. In this multicenter retrospective study, we aimed to clarify the efficacy and safety of TAF in treatment-naïve patients with chronic hepatitis B, focusing on the reduction in HBcrAg levels. METHODS: Patients were treated with TAF monotherapy for 96 weeks, and the kinetics of HBcrAg during treatment and the factors associated with HBcrAg response (defined as a change in HBcrAg of -1 log IU/mL from baseline) were evaluated. RESULTS: The study population comprised 241 patients, 36.9% of whom were HBeAg-positive. The median baseline HBcrAg level was 4.7 log IU/mL. The median change in HBcrAg from baseline was -1.1 log IU/mL at 96 weeks after treatment. The HBcrAg response rate at 96 weeks was 56.6% (43/76). Multivariate analysis revealed high alanine transaminase level as an independent baseline factor associated with HBcrAg response at 96 weeks of treatment (p = 4.53 × 10-6). No correlation was found between the HBcrAg and hepatitis B surface antigen kinetics in patients treated with TAF monotherapy. CONCLUSIONS: In TAF monotherapy for patients with chronic hepatitis B, HBcrAg levels were significantly decreased and baseline alanine transaminase level is an important factor associated with HBcrAg reduction. As no correlation was found between HBcrAg and reduced hepatitis B surface antigen levels in this study, HBcrAg kinetics in addition to hepatitis B surface antigen may need to be monitored during TAF treatment.
RESUMEN
AIM: Elderly patients are believed to have a reduced immune capacity, which may make immunotherapy less effective. The aim of this study was to compare the therapeutic outcome of atezolizumab plus bevacizumab (Atez/Bev) and lenvatinib (LEN) for advanced hepatocellular carcinoma (HCC) in patients aged 80 years and older. METHODS: From March 2018 to July 2022, 170 and 92 elderly patients who received LEN and Atez/Bev as first-line treatment, respectively, were retrospectively analyzed. RESULTS: The median ages of the Atez/Bev and LEN groups were 83.0 (8.01-86.0) and 83.0 (82.0-86.0) years (p = 0.3), respectively. Men accounted for approximately 70% of the patients in both groups. The objective response rate was 35.9% in the LEN group and 33.7% in the Atez/Bev group (p = 0.8), whereas the disease control rates in the LEN and Atez/Bev groups were 62.9% and 63.0%, respectively (p = 1.0). The median progression-free survival (PFS) in the LEN and Atez/Bev groups was 6.3 and 7.2 months, respectively, which were not significantly different (p = 0.2). The median overall survival (OS) was 17.9 months in the LEN group and 14.0 months in the Atez/Bev group. This difference was not statistically significant (p = 0.7). In multivariate analyses, the choice of treatment (LEN vs. Atez/Bev) showed no association with PFS or OS. The Atez/Bev group had a significantly higher rate of postprogression treatment (59.0% vs. 35.7%, p = 0.01) and a lower rate of discontinuation due to adverse events (69 [40.6%] vs. 19 [20.7%], p < 0.001) compared to the LEN group. CONCLUSIONS: Atezolizumab plus bevacizumab showed comparable effectiveness to LEN in HCC patients aged 80 years and older. Given the results of postprogression treatment and discontinuation due to adverse events, Atez/Bev could serve as a first-line treatment even for elderly HCC patients.
RESUMEN
BACKGROUND: Although the efficacy of atezolizumab has been demonstrated in randomized controlled trials, its long-term efficacy and association with adverse events in real-world practice are unknown. This study was designed to shed light on these issues. METHODS: In this multicenter retrospective study, data were collected from patients with advanced hepatocellular carcinoma treated with atezolizumab plus bevacizumab in seven institutions in Japan. The authors focused on the efficacy and adverse events related to vascular endothelial growth factor (VEGF) inhibition. RESULTS: A total of 123 patients were enrolled in this study. The median progression-free survival (PFS) for the first-line treatment group was 8.0 months (95% confidence interval [CI], 6.1-9.9), whereas the median PFS for the second- or later-line treatment group was 4.1 months (95% CI, 2.6-5.7), which was significantly worse than that of the first-line treatment group (p = .005). Twenty-seven patients had interrupted bevacizumab treatment. Proteinuria accounted for the largest proportion of bevacizumab treatment interruptions. The cumulative incidence rate of bevacizumab interruption due to anti-VEGF-related adverse events was significantly higher in patients with hypertension and/or diabetes mellitus than in those without (p = .026). The landmark analysis showed that patients experienced bevacizumab interruption by 24 weeks from treatment initiation had poorer PFS than those who did not (p = .013). CONCLUSIONS: The PFS of atezolizumab plus bevacizumab as first-line treatment mostly replicates that of a global phase 3 trial. Interrupted bevacizumab treatment was more common in patients with hypertension and/or diabetes mellitus, which may be associated with worsening long-term PFS. PLAIN LANGUAGE SUMMARY: Atezolizumab plus bevacizumab has been the standard front line systemic therapy for advanced hepatocellular carcinoma. With the growing incidence of fatty liver due to metabolic syndrome as a background liver disease for hepatocellular carcinoma, the rate of comorbid hypertension and diabetes mellitus has been increasing accordingly. The present study demonstrated the cumulative incidence rate of bevacizumab interruption due to anti-VEGF-related adverse events was significantly higher in patients with hypertension and/or diabetes mellitus. The landmark analysis clarified that interruption of bevacizumab might be a risk of impaired efficacy of atezolizumab plus bevacizumab over the long term in patients with advanced hepatocellular carcinoma.

INTRODUCTION: This study investigated the relationship between nutritional status, as determined by the prognostic nutritional index (PNI), and outcomes in patients with unresectable hepatocellular carcinoma (HCC) treated with atezolizumab plus bevacizumab (Atez/bev). METHODS: The study analyzed 485 HCC patients treated with Atez/bev. RESULTS: There were 342 patients with a low PNI (<47) and 143 patients with a high PNI (≥47). The median follow-up duration was 9.4 (6.0-14.3) months. Multivariate Cox hazards analysis showed that an α-fetoprotein level ≥100 ng/mL (hazard ratio (HR), 2.217; 95% confidence interval (CI), 1.588-3.095; p < 0.001), and PNI ≥47 (HR, 0.333; 95% CI, 0.212-0.525; p < 0.001) were independently associated with overall survival. Multivariate analysis showed that an α-fetoprotein level ≥100 ng/mL (HR, 1.690; 95% CI, 1.316-2.170; p < 0.001) and PNI ≥47 (HR, 0.696; 95% CI, 0.528-0.918; p = 0.010) were independently associated with progression-free survival. Cumulative overall and progression-free survival rates differed significantly by PNI (p < 0.001 and p < 0.002, respectively). In a subgroup analysis using inverse probability weighting adjustment in patients with albumin-bilirubin grade 1 (n = 173), univariate Cox hazards analysis showed that a PNI ≥47 (HR, 0.502; 95% CI, 0.260-0.991; p = 0.047) was significantly associated with overall survival. Spline curve analysis revealed that a PNI of approximately 34-48 is an appropriate cutoff for predicting good overall and progression-free survival. CONCLUSION: The PNI, a biomarker of nutritional status, can predict prognosis in patients with HCC treated with Atez/bev, even those who are considered to have a good prognosis due to good liver function.

INTRODUCTION: Systemic treatment is generally recommended for Child-Pugh (CP) A status patients with an unresectable hepatocellular carcinoma (uHCC). This study aimed to elucidate differences regarding therapeutic efficacy between lenvatinib (LEN), a multi-molecular target agent, and atezolizumab plus bevacizumab (Atez/Bev), a newly developed immune-combined therapeutic regimen for CP-B patients affected by uHCC. METHODS: From April 2018 to July 2022, 128 patients with uHCC treated with Atez/Bev (n = 29) or LEN (n = 99) as the initial systemic treatment were enrolled (median age 71 years; males 97; CP score 7:8:9 = 94:28:6; median albumin-bilirubin score -1.71). Therapeutic response was evaluated using RECIST, version 1.1. Clinical features and prognosis were retrospectively examined. RESULTS: There were no significant differences between the Atez/Bev and LEN groups in regard to best response (CR:PR:SD:PD = 0:5:12:7 vs. 5:22:25:20, p = 0.415), progression-free survival (PFS) (median 5.0 [95% CI: 2.4-7] vs. 5.5 [95% CI: 3.4-7.9] months, p = 0.332), or overall survival (OS) (5.8 [95% CI: 4.3-11] vs. 8.8 [95% CI: 6.1-12.9] months, p = 0.178). Adverse events (any grade/≥ grade 3) were observed in 72.4%/17.2% (n = 21/5) of patients treated with Atez/Bev and 78.8%/25.3% (n = 78/25) of those treated with LEN (p = 0.46/0.46). DISCUSSION: This retrospective study found no significant differences regarding PFS or OS between CP-B patients given Atez/Bev or LEN as initial systemic treatment for uHCC.

INTRODUCTION: Lack of an established methodology for post-progression systemic treatment following atezolizumab plus bevacizumab (Atez/Bev) administration is an important clinical issue. The present study aimed to elucidate the potential of lenvatinib as a second-line treatment option after Atez/Bev failure. METHODS: From 2020 to 2022, 101 patients who received lenvatinib as second-line treatment were enrolled (median 72 years, males 77, Child-Pugh A 82, BCLC-A:B:C:D = 1:35:61:4), while 29 treated with another molecular targeting agent (MTA) during the period as second-line treatment were enrolled as controls. The therapeutic efficacy of lenvatinib given as second-line treatment was retrospectively evaluated. RESULTS: Median progression-free survival/median overall survival for all patients was 4.4/15.7 months and for those with Child-Pugh A was 4.7 months/not-reached. When prognosis was compared with patients who received another MTA, there was no significant difference for PFS (3.5 months, p = 0.557) or OS (13.6 months, p = 0.992), and also no significant differences regarding clinical background factors. mRECIST findings showed that objective response and disease control rates in patients treated with lenvatinib were 23.9% and 70.4%, respectively (CR:PR:SD:PD = 3:14:33:21), while those shown by RECIST, ver. 1.1, were 15.4% and 66.2%, respectively (CR:PR:SD:PD = 1:10:36:24). Adverse events (any grade ≥10%) were appetite loss (26.7%) (grade 1:2:3 = 2:15:10), general fatigue (21.8%) (grade 1:2:3 = 3:13:6), protein in urine (16.8%) (grade 1:2:3 = 0:4:13), and hypertension (13.9%) (grade 1:2:3 = 1:8:5). CONCLUSION: Although lenvatinib treatment might not provide a pseudo-combination immunotherapy effect following Atez/Bev failure, lenvatinib when used as second-line treatment after Atez/Bev failure might be expected to be comparable as compared to its use as first-line treatment.

BACKGROUND: Hyperprogressive disease (HPD) is a phenomenon with greatly accelerated tumor growth and clinical deterioration rates compared to pre-therapy, in patients treated with immune checkpoint inhibitors (ICI). The aim of this study is to clarify the reality of HPD in patients with advanced hepatocellular carcinoma (HCC) who were treated with atezolizumab plus bevacizumab (Atez/Bev) using tumor dynamics. METHODS: Medical records of consecutive patients with advanced HCC who were treated with Atez/Bev were retrospectively reviewed. HPD was defined as a more than two- or fourfold increase in tumor growth rate (TGR) or tumor growth kinetics rate (TGKR) before and after treatment. Overall survival (OS) and baseline characteristics with or without HPD were analyzed. RESULTS: A total of 85 patients were included in the analysis. When HPD was defined as a twofold of TGR or TGKR, 8 patients (8/85, 9.4%) had HPD and 11 had PD without HPD. A total of 5 patients (5/85, 5.9%) were diagnosed with HPD and 14 with PD without HPD when HPD was defined as a fourfold of TGR or TGKR. No significant difference was observed in the baseline characteristics between HPD and non-HPD. CONCLUSION: The prevalence of HPD in patients with advanced HCC treated with Atez/Bev was lower than those treated with nivolumab monotherapy. The HPD mechanism in ICI combined with antibodies targeting vascular endothelial growth factor (VEGF) remains to be elucidated.

AIM: The present study focused on Geriatric Nutritional Risk Index (GNRI), which is based on bodyweight and serum albumin, and known as an easy-to-use nutritional assessment tool in clinical settings, to elucidate the prognostic predictive ability of GNRI in patients treated with atezolizumab plus bevacizumab (Atez/Bev) for hepatocellular carcinoma (HCC). METHODS: A total of 525 HCC patients treated with Atez/Bev, based on their classification of unsuitable status for curative treatments and/or transarterial catheter chemoembolization, were enrolled (Child-Pugh A:B:C = 484:40:1, Barcelona Clinic Liver Cancer stage 0:A:B:C:D = 7:25:192:283:18). Prognosis was evaluated retrospectively using GNRI. RESULTS: Atez/Bev was used in 338 of the present cohort as first-line systemic chemotherapy (64.4%). Median progression-free survival based on GNRI indicating normal, mild decline, moderate decline, and severe decline was 8.3, 6.7, 5.3, and 2.4 months, respectively, whereas median overall survival was 21.4, 17.0, 11.5. and 7.3 months, respectively (both p < 0.001). The concordance index (c-index) values of GNRI for predicting prognosis (progression-free survival/overall survival) were superior to those of Child-Pugh class and albumin-bilirubin grade (0.574/0.632 vs. 0.527/0.570 vs. 0.565/0.629). As a subanalysis, muscle volume loss was observed in 37.5% of 256 patients with computed tomography data available. Along with GNRI decline, frequency of muscle volume loss became progressively larger (normal vs. mild vs. moderate vs. severe = 17.6% vs. 29.2% vs. 41.2% vs. 57.9%, p < 0.001), and a GNRI value of 97.8 was predictive of its occurrence (AUC 0.715, 95% CI 0.649-0.781; specificity/sensitivity = 0.644/0.688). CONCLUSION: These findings indicate that GNRI is an effective nutritional prognostic tool for predicting prognosis and muscle volume loss complication in HCC patients treated with Atez/Bev.
RESUMEN
AIM: This retrospective study aimed to investigate the impact of proton pump inhibitor treatment (PPI) and antibiotic treatment on the therapeutic outcomes of hepatocellular carcinoma (HCC) patients receiving atezolizumab and bevacizumab (Atez/Bev). METHODS: The present study included a total of 441 HCC patients who were treated with Atez/Bev in 20 Japanese institutions from September 2020 to April 2022. We adopted the inverse probability of treatment weight to adjust for imbalance in the baseline characteristics of patients with and without PPI treatment as well as patients with and without antibiotic treatment. RESULTS: The progression-free survival (PFS) and overall survival (OS) of patients with and without PPI treatment did not differ to a statistically significant extent. In the weighted cohort, the difference in PFS and OS between the patients with and without PPI did not reach statistical significance (median PFS, 7.0 vs. 6.5 months, p = 0.07; 1-year survival rate 66.3% and 73.8%, p = 0.9). The PFS and OS in patients with antibiotic treatment were worse in comparison to patients without antibiotic treatment (median PFS, 3.8 vs. 7.0 months, p = 0.007; 1-year survival rate 58.8% and 70.3%, p = 0.01). In the weighted cohort, the PFS and OS of the two groups did not differ to a statistically significant extent (median PFS, 3.8 vs. 6.7 months, p = 0.2; 1-year survival rate, 61.8% and 71.0%, p = 0.6). CONCLUSIONS: The therapeutic outcomes of Atez/Bev in HCC patients did not differ between patients with and without PPI treatment or between patients with and without antibiotic treatment.
RESUMEN
BACKGROUND AND AIM: Apolipoprotein A2 (apoA2) isoforms have been reported to undergo the aberrant processing in pancreatic cancer and pancreatic risk populations compared with that in healthy subjects. This study aimed to clarify whether apoA2 isoforms were as useful as N-benzoyl-p-aminobenzoic acid (BT-PABA) test for exocrine pancreatic dysfunction markers in patients with early chronic pancreatitis (ECP). METHODS: Fifty consecutive patients with functional dyspepsia with pancreatic enzyme abnormalities (FD-P) (n = 18), with ECP (n = 20), and asymptomatic patients with pancreatic enzyme abnormalities (AP-P) (n = 12) based on the Rome IV classification and the Japan Pancreatic Association were enrolled in this study. The enrolled patients were evaluated using endoscopic ultrasonography and endoscopic ultrasonography elastography. Five pancreatic enzymes were estimated. Pancreatic exocrine function was analyzed using the BT-PABA test. Lighter and heavier apoA2 isoforms, AT and ATQ levels were measured by enzyme-linked immunosorbent assay methods. RESULTS: There were no significant differences in clinical characteristics such as age, gender, body mass index, alcohol consumption and smoking among patients with AP-P, FD-P, and ECP. The BT-PABA test and lighter apoA2 isoform, AT level in the enrolled patients had a significant correlation (P < 0.01). The BT-PABA test in patients with ECP was significantly lower (P = 0.04) than that in AP-P. ApoA2-AT level in patients with ECP was lower than that in AP-P, albeit, insignificantly. Interestingly, apo A2-AT level was significantly (P = 0.041) associated with exocrine pancreatic insufficiency by multiple logistic regression analysis. CONCLUSIONS: ApoA2-AT level is a useful tool to evaluate exocrine pancreatic insufficiency in the early stage of chronic pancreatitis.

BACKGROUND AND AIM: The study goal was to compare the outcomes of patients with unresectable hepatocellular carcinoma (HCC) who received atezolizumab plus bevacizumab (Atezo/Bev) as either first- or later-line systemic therapy. METHODS: A total of 430 patients with HCC treated with Atezo/Bev at 22 institutions in Japan were included. Patients treated with Atezo/Bev as first-line therapy for HCC were defined as the first-line group (n = 268) while those treated with Atezo/Bev as second- or later-line therapy were defined as the later-line group (n = 162). RESULTS: The median progression-free survival times in the first- and later-line groups were 7.7 months (95% confidence interval [CI], 6.7-9.2) and 6.2 months (95% CI, 5.0-7.7) (P = 0.021). Regarding treatment-related adverse events, hypertension of any grade was more common in the first-line group than in the later-line group (P = 0.025). Analysis adjusted by inverse probability weighting, including patient and HCC characteristics, showed that the later-line group (hazard ratio, 1.304; 95% CI, 1.006-1.690; P = 0.045) was significantly associated with progression-free survival. In patients with Barcelona Clinic Liver Cancer stage B, the median progression-free survival times in the first- and later-line groups were 10.5 months (95% CI, 6.8-13.8) and 6.8 months (95% CI, 5.0-9.4) (P = 0.021). Among patients with a history of lenvatinib therapy, the median progression-free survival times in the first- and later-line groups were 7.7 months (95% CI, 6.3-9.2) and 6.2 months (95% CI, 5.0-7.7) (P = 0.022). CONCLUSION: The use of Atezo/Bev as first-line systemic therapy in patients with HCC is expected to prolong survival.

INTRODUCTION: Adverse events (AEs) of urinary protein from monoclonal antibodies against vascular endothelial growth factor are factors that often inhibit systemic therapy for unresectable hepatocellular carcinoma (uHCC). This study aimed to elucidate risk factors of urinary protein in the early period (<12 weeks) of atezolizumab plus bevacizumab treatment (Atez/Bev). METHODS: From 2020 to June 2022, 193 uHCC patients treated with Atez/Bev at our affiliated hospitals were enrolled (median 73 years, 158 males, 183 Child-Pugh A, BCLC-0:A:B:C = 1:7:73:112). AEs related to urinary protein (≥G2) within 12 weeks were defined as significant, and related clinical features were analyzed retrospectively. RESULTS: In analyses of risk factors of urinary protein-related AEs during the first 12 weeks after starting Atez/Bev using a logistic regression method, univariate analysis showed positive for hypertension (odds ratio [OR] 3.54, 95% CI: 1.28-9.80, p = 0.015) and baseline urinary protein and urine creatinine ratio (UPC: ≥0.16) (OR: 2.52, 95% CI: 1.09-5.83, p = 0.031) as pretreatment clinical factors, while elevation of urinary protein in the early period (baseline to 3 weeks) with delta UPC per 3 weeks (ΔUPC/3W) (≥0.23) (OR: 15.80, 95% CI: 6.15-40.50, p < 0.001) was a clinical factor after starting treatment. Multivariate analysis of only baseline clinical factors revealed positive for history of hypertension as the only predictive factor (OR: 3.20, 95% CI: 1.14-8.95, p = 0.027), while only ΔUPC/3W (≥0.23) (OR: 14.40, 95% CI: 4.91-42.00, p < 0.001) were noted in multivariate analysis including ΔUPC/3W. Predictive factors for ΔUPC/3W (≥0.23) were hypertension (OR: 3.50, 95% CI: 1.23-99.90, p = 0.019) and UPC (≥0.16) (OR: 6.12, 95% CI: 2.61-14.30, p < 0.001) in multiple analysis. DISCUSSION/CONCLUSION: Urinary protein-related AEs are frequently observed during Atez/Bev treatment in uHCC patients with elevated ΔUPC/3W (≥0.23), and ΔUPC/3W (≥0.23) is often seen in patients with hypertension and/or UPC (≥0.16).

BACKGROUND: It is unclear whether prophylactic endoscopic closure after colorectal endoscopic submucosal dissection (ESD) reduces the risk of postoperative adverse events due to variability in lesion characteristics. Therefore, we conducted a retrospective study using propensity score matching to evaluate the efficacy of prophylactic clip closure in preventing postoperative adverse events after colorectal ESD. METHODS: This single-center retrospective cohort study included 219 colorectal neoplasms which were removed by ESD. The patients were allocated into the closure and non-closure groups, which were compared before and after propensity-score matching. Post-ESD adverse events including major and minor bleeding and delayed perforation were compared between the two groups. RESULTS: In this present study, 97 and 122 lesions were allocated to the closure and non-closure groups, respectively, and propensity score matching created 61 matched pairs. The rate of adverse events was significantly lower in the closure group than in the non-closure group (8% vs. 28%, P = 0.008). Delayed perforation occurred in two patients in the non-closure group, whereas no patient in the closure group developed delayed perforation. In contrast, there were no significant differences in other postoperative events including the rate of abdominal pain; fever, white blood cell count, and C-reactive protein; and appetite loss between the two groups. CONCLUSIONS: Propensity score matching analysis demonstrated that prophylactic closure was associated with a significantly reduced rate of adverse events after colorectal ESD. When technically feasible, mucosal defect closure after colorectal ESD may result in a favorable postoperative course.

BACKGROUND/AIM: Although systemic therapy is recommended for patients with multiple intermediate stage unresectable hepatocellular carcinoma (u-HCC) classified as beyond the up-to-7 criteria (UT-7 out/multiple) as a transcatheter arterial chemoembolization (TACE) unsuitable condition, few reports have examined the therapeutic efficacy of atezolizumab plus bevacizumab combination therapy (Atez/Bev) in such cases. This study aimed to elucidate the therapeutic response of Atez/Bev in u-HCC patients classified as UT-7 out/multiple. MATERIAL/METHODS: From September 2020 to September 2021, 95 u-HCC Japanese patients classified as UT-7 out/multiple/Child-Pugh A were enrolled from 21 institutions (median age 76 years, males 73, Child-Pugh 5:6 = 68:27, TNM stage II:III = 17:78). Therapeutic response was retrospectively evaluated using Response Evaluation Criteria in Solid Tumors (RECIST), ver. 1.1 and modified RECIST (mRECIST). RESULTS: Atez/Bev was given as first-line treatment to 52 (54.7%). Objective response rate (ORR)/disease control rate (DCR) at six weeks of RECIST and mRECIST were 17.7%/84.7% and 42.5%/86.2%, respectively. Median PFS was 8.0 months (median observation period: 6.0 months). Child-Pugh A/modified Albumin-bilirubin grade (mALBI) 1 and 2a at baseline, 3, 6, and 9 weeks, were 100%/69.4%, 89.8%/57.3%, 94.8%/65.3%, and 91.4%/60.0%, respectively. Among adverse events (any-grade, >10%) during the present observation period, general fatigue was most frequent (23.2%), followed by urine protein (21.1%), appetite loss (20.0%), and hypertension (13.7%). CONCLUSION: Atez/Bev treatment showed favorable therapeutic response with less influence on hepatic function, suggesting it as a useful therapeutic option for patients with such condition.
RESUMEN
BACKGROUND/AIM: Atezolizumab plus bevacizumab (Atez/Bev) treatment is recommended for unresechepatocellular carcinoma (u-HCC) patients classified as Child-Pugh A (CP-A). This study aimed to elucidate the prognosis of patients treated with Atez/Bev, especially CP-A and -B cases. MATERIALS/METHODS: From September 2020 to March 2022, 457 u-HCC patients treated with Atez/Bev were enrolled (median age 74 years, male:female = 368:89, CP-A:CP-B = 427:30, Child-Pugh score [CPS] 5:6:7:8:9 = 271:156:21:8:1). Therapeutic response was evaluated using RECIST ver.1.1. Clinical features and prognosis were retrospectively evaluated. RESULTS: There were no significant differences between CP-A and -B patients in regard to best response (CR:PR:SD:PD = 16:91:194:81 vs. 0:7:13:8, p = 0.739; objective response rate/disease control rate = 28.0%/78.8% vs. 25.0%/71.4%). Analysis performed using inverse probability weighting adjustments of clinical factors other than those related to hepatic reserve function with a p value < 0.10 for comparisons between patients with CP-A and -B showed that the progression-free survival (PFS) rate for CP-A cases was better (6-/12-/18-month: 58.2%/36.1%/27.8% vs. 49.6%/8.7%/non-estimable [NE], p < 0.001), as was overall survival (OS) rate (6-/12-/18-month: 89.9%/71.7%/51.4% versus 63.6%/18.4%/NE; p < 0.001). Median PFS (mPFS) and median OS (mOS) for the CPS-5 were 9.5 months/NE, and 5.1/14.0 months for the CPS-6 (both p < 0.001). Furthermore, for modified albumin-bilirubin grade (mALBI)-1/2a/2b, mPFS was 9.4/8.5/5.3 months (p < 0.001) and mOS was NE/17.8/13.4 months (p < 0.001). CONCLUSION: Better hepatic function, such as mALBI grade 1 or 2a are thought to indicate a better condition for obtaining sufficient prognosis with Atez/Bev treatment for u-HCC patients, whereas for CP-B patients, who mainly shown an mALBI grade of 2b or 3, Atez/Bev might have less therapeutic efficacy.
RESUMEN
AIM: The present study focused on the association of early bevacizumab (Bev) interruption with the clinical outcome of atezolizumab plus bevacizumab. METHODS: This retrospective study included 239 patients with advanced hepatocellular carcinoma receiving atezolizumab/Bev from September 2020 to June 2021 at 16 different institutions in Japan. We conducted a 9-week landmark analysis to investigate the association of Bev interruption due to adverse events with the therapeutic efficacy. RESULTS: The median age was 73.0 (68.0-80.0) years old, with 195 (81.6%) men. The objective response rate was significantly higher in patients without Bev interruption than in those with it (34.5% vs. 17.3%, p = 0.038). The median progression-free survival (PFS) was 6.5 months (95% confidence interval [CI] 4.5-9.7) and 9.0 months (95% CI 7.1-not applicable) in patients with and without Bev interruption, respectively, with statistical significance (p = 0.021). The 12-month overall survival (OS) rates in patients with and without Bev interruption were 49.4% (CI 27.7%-67.9%) and 82.2% (95% CI 70.3%-89.6%), respectively, showing a significant difference (p = 0.004). The presence of Bev interruption was a significant factor associated with the PFS (p = 0.021) and OS (p = 0.008). A multivariate analysis showed that modified albumin-bilirubin 2b (p < 0.001) and later-line treatment (p = 0.018) were unfavorable factors associated with Bev interruption. Liver injury, appetite loss, protein urea, and ascites or hepatic edema were more frequently found in patients with Bev interruption than in those without it. CONCLUSIONS: Early Bev interruption was an unfavorable factor associated with the PFS and OS. Good liver function and treatment settings may be associated with maintaining Bev treatment.
