Background/Aim: With the development of systemic treatment methods for unresectable hepatocellular carcinoma (uHCC), the concept of unsuitable for transcatheter arterial chemoembolization (TACE) has become important. This study aimed to establish a simple predictive scoring system for determining TACE unsuitable status. Materials/Methods: From 1998 to 2015, 196 patients with intermediate-stage uHCC with Child-Pugh A (score 5:6 = 108:88) and given TACE as the initial treatment were enrolled. At the baseline, tumor burden (Milan criteria-out, up-to-7 in/out, and up-to-11 in/out: 0–2 points) and modified albumin-bilirubin grade 1/2a or 2b (0–1 point) were added to determine the score for TACE unsuitable (CITRUS-MICAN score; low <2 and high ≥2). In addition, a previously reported tumor marker (TM) score, in which alpha-fetoprotein (AFP) was ≥100 ng/mL, fucosylated AFP ≥10%, and des-gamma-carboxy prothrombin ≥100 mAU/mL (each 1 point) (total 0, 1, or ≥2 points), was used for additionally evaluating tumor malignancy potential. Prognosis was retrospectively evaluated based on those scores. Results: Median survival time (MST) was better for low compared to high CITRUS-MICAN score (42.0 vs. 26.4 months) (p = 0.002). A 2-step evaluation using the combination of CITRUS-MICAN and TM scores showed an MST of 43.2 months for low CITRUS-MICAN/TM score 0/1 (rank-A) and 39.6 months for low CITRUS-MICAN/TM score ≥2 (rank-B2), while it was 46.8 months for high CITRUS-MICAN/TM score 0 (rank-B1), 28.8 months for high CITRUS-MICAN/TM score 1 (rank-B2), and 22.8 months for high CITRUS-MICAN/TM score ≥2 (rank-C). For rank-A cases (n = 51), MST was 43.2 months, while it was 46.8 months for rank-B1 (n = 12), 31.2 months for rank-B2 (n = 82), and 22.8 months for rank-C (n = 51) (p = 0.001). Conclusion: The results showed that rank-C indicates absolute TACE unsuitable status. For rank-A patients, good prognosis with TACE can be expected, while TACE refractoriness status during the clinical course should be carefully evaluated so as to anticipate the appropriate timing for switching to systemic treatment in rank-B1 and -B2 patients.

Background/Aim: Few studies have examined the details of nutritional status in patients with unresectable hepatocellular carcinoma (u-HCC) undergoing systemic chemotherapy with lenvatinib. We evaluated the prognostic/predictive value of nutritional status using Onodera's prognostic nutritional index (O-PNI) for overall survival among patients with u-HCC treated with lenvatinib. Methods: Three-hundred and seventy-five u-HCC patients treated with lenvatinib were enrolled (median age 72 years; Child-Pugh class A/B/C: n = 312/60/3; BCLC stage A/B/C/D: n = 2/159/212/2). We examined median survival time (MST) and time to progression (TTP) in all patients (n = 375), prognosis according to the O-PNI (high/low: >40/≤40) in 298 patients with lymphocyte findings, and the prognostic/predictive values of Child-Pugh stage, albumin-bilirubin (ALBI)/modified ALBI (mALBI) grade, and O-PNI for Chemotherapy grade (OPNIC grade 1/2/3: O-PNI >40/≤40 to >36/≤36). Results: The MST and TTP were 16.6 and 8.0 months, respectively. The MST and TTP according to the O-PNI (>40/≤40) were "not reached" (NR)/12.4 months (p < 0.001) and 10.0/6.1 months (p = 0.012), respectively. There was a good correlation noted between ALBI score and O-PNI (r = −0.939, p < 0.001). The predictive value of the O-PNI for mALBI grade 2a was 36.0 (specificity/sensitivity = 0.894/0.942; area under the curve [AUC] = 0.978), while that for mALBI grade 1 was 39 (specificity/sensitivity = 0.920/0.929; AUC = 0.972), which was very similar to a high O-PNI. The MST analyzed with the OPNIC in the 298 patients was NR/16.2/10.4 months for OPNIC grade 1/2/3 (p < 0.001), respectively, and the c-index was 0.632, the same as that for mALBI grade (0.632), while that for Child-Pugh class was 0.571. Conclusions: OPNIC grading might have a potential for easy substitution of mALBI grading. A good nutritional status (OPNIC grade 1) or mALBI grade 1 is the best indication for lenvatinib use, while with an OPNIC grade 3, lenvatinib might be not suitable. [ABSTRACT FROM AUTHOR]

Background/Aim: Lenvatinib (LEN) has been developed for the treatment of unresectable hepatocellular carcinoma (u-HCC). We aimed to elucidate the relative change in hepatic reserve function early following LEN treatment in affected patients. Materials/Methods: From March 2018 to April 2019, 123 u-HCC patients (median age 71 years; male:female ratio 95:28; Child-Pugh score 5:6:7 = 65:50:8; modified albumin-bilirubin [mALBI] grade 1:2a:2b:3 = 44:28:50:1, Barcelona Clinic Liver Cancer stage A:B:C = 1:49:73) were enrolled. Relative changes in hepatic reserve function at 2 and 4 weeks after starting LEN were retrospectively evaluated. Results: The median survival was 11.3 months. The Child-Pugh score declined from the start to 4 weeks after commencing LEN (score 5:6:7:8:9:≥10 = 65:50:8:0:0:0 vs. 50:39:22:8:0:4, p < 0.001). A comparison among ALBI scores at the start of LEN and those at 2 and 4 weeks revealed significant relative changes (–2.36 ± 0.45 to –2.20 ± 0.49 at 2 weeks, –2.15 ± 0.50 at 4 weeks, p < 0.001, Bonferroni method), while there was no significant difference between those at 2 and 4 weeks (p= 0.210, Bonferroni method). Assessments of relative changes of ALBI score in patients divided by mALBI grade 1, 2a, and 2b or more showed a significant decline in score regardless of grade (–2.82 ± 0.17 to –2.53 ± 0.34, p < 0.001; –2.46 ± 0.10 to –2.31 ± 0.33, p = 0.017; and –1.90 ± 0.26 to –1.75 ± 0.42, p= 0.009, respectively). Conclusion: Decline in hepatic function is common in the early stage (≤4 weeks, especially within 2 weeks) after introducing LEN. It is important to introduce molecular targeting agent drugs for u-HCC in patients with better hepatic function, who show transarterial catheter chemoembolization failure, as much as possible, along with consideration of the negative influence of LEN on the early response of hepatic function.

Background/Aim: We evaluated clinical factors related to improved prognosis of unresectable hepatocellular carcinoma patients (u-HCC), who were treated with tyrosine kinase inhibitor (TKI) sequential therapy, including lenvatinib (LEN). Materials/Methods: We enrolled 84 u-HCC cases treated with TKIs including LEN from March 2018 to January 2019 (median age 71 years, 63 males, Child-Pugh score (CPS) 5/6/7 = 62/21/1, tumor-node-metastasis stage of Liver Cancer Study Group of Japan 6th (TNM-LCSGJ) II/III/IVa/IVb = 12/30/5/37, Barcelona Clinic Liver Cancer stage B/C = 33:51). Clinical findings at introduction of the initial TKI were retrospectively evaluated. Results: The median albumin-bilirubin (ALBI) score at introduction of the initial TKI (sorafenib [SOR]/LEN = 80/4) was –2.56, and the past number of transarterial catheter chemoembolization was 3 (IQR: 2–5) (second-line: regorafenib [REG]/LEN/SOR = 31/49/4, third-line: LEN/REG = 31:1). The total period of administration with TKIs showed a good relationship with overall survival (OS) (r = 0.946, 95% confidence interval [CI]: 0.918–0.965, p < 0.001). The prognosis of the entire cohort was good (estimated median survival time: 46.4 months, 1-/2-/3-year OS rate [OSR] = 87.7/63.0/57.2%). A modified-ALBI grade (mALBI) of 2b (ALBI score >–2.27) was the only significant factor at the start of the initial TKI for poor prognosis (hazard ratio 2.319, 95% CI: 1.064–5.052, p = 0.034), while CPS (≥6) was not. Although there was no significant difference in TNM-LCSGJ (p = 0.213), the prognosis of patients with mALBI 1/2a (n = 66) showed better prognosis as compared to those with mALBI 2b (n = 18) (1-year/2-year/3-year OSR = 89.1/69.8/66% vs. 82.4/47.1/23.5%, p = 0.029). Conclusion: Good hepatic function (mALBI 1/2a) at introduction of the initial TKI is a requirement for improved prognosis of u-HCC undergoing TKI sequential therapy. [ABSTRACT FROM AUTHOR]

\nIntroduction: Gastrointestinal varices rupture is considered to be prone to occur during atezolizumab and bevacizumab (Atez/Bev) treatment. This study aimed to investigate predictive factors affecting the increase in spleen volume (SpV) and the association of SpV variation with the clinical outcomes of Atez/Bev. Methods: A total of 164 HCC patients were included in this retrospective multicenter study. We measured SpV based on CT scans obtained before treatment and at evaluations. We used the inverse probability of treatment weight to address the imbalance between patient characteristics. Results: The median pretreatment SpV was 184 (130–257) cm3 and the median SpV variation was 27 (9–60) cm3. An increase in the SpV was observed in 140 patients (85.4%). Age <74 years (p = 0.03), mALBI grade 2b or 3 (p = 0.03), and pretreatment SpV ≥184 cm3 (p < 0.001) were significantly associated with increased SpV. There were no significant differences in progression-free survival (PFS) or overall survival (OS) between patients with SpV variation <25 cm3 and those with SpV variation ≥25 cm3 in the crude (p = 0.3 and 0.7) and IPTW-weighted cohorts (p = 0.08 and 0.8, respectively). Regarding pretreatment SpV, there were no significant differences in PFS or OS between patients with and without pretreatment spleen enlargement in the crude (both p = 0.3) and IPTW-weighted cohort (p = 0.6 and 0.3, respectively). Conclusion: Caution is warranted to detect the aggravation of portal hypertension when administering Atez/Bev to young patients or patients with an impaired liver function or pretreatment spleen enlargement. The impact of spleen modulation by Atez/Bev appears to be limited on clinical efficacy. Immunotherapy is now the standard of care for systemic therapy in hepatocellular carcinoma (HCC). The combination of atezolizumab and bevacizumab (Atez/Bev) is recommended for the first-line treatment, while gastrointestinal varices rupture is likely to be observed during Atez/Bev. Gastrointestinal varices rupture is a fatal event and developed due to portal hypertension. Spleen volume (SpV) plays an important role in portal hypertension based on previous studies, and we examined variation in SpV during Atez/Bev treatment and investigated predictive factors that affect the increase in SpV and the association of SpV variation and pretreatment SpV with the clinical outcome of Atez/Bev. The median pretreatment SpV was 184 (130–257) cm3 and the median SpV variation was 27 (9–60) cm3. An increase in the SpV was observed in 140 patients (85.4%). Age <74 years (p = 0.03), mALBI grade 2b or 3 (p = 0.03), and pretreatment SpV ≥184 cm3 (p < 0.001) were significantly associated with increased SpV. The present study revealed that there were no significant differences in progression-free survival and overall survival between patients with and without pretreatment spleen enlargement, as well as between patients with SpV variation ≥25 cm³ and those with SpV variation <25 cm³. In conclusion, caution is warranted to detect the aggravation of portal hypertension when administering Atez/Bev to young patients or those with an impaired liver function or pretreatment spleen enlargement. The impact of spleen modulation by Atez/Bev appears to be limited on clinical efficacy. [ABSTRACT FROM AUTHOR]

Introduction: The most frequently used first-line treatment in patients with advanced hepatocellular carcinoma (HCC) is atezolizumab plus bevacizumab. Upon progression after this treatment, the standard of care in many countries is sorafenib, due to the lack of reimbursement for other drugs. Several randomized trials are currently underway to clarify the best second-line therapy in patients with HCC. This real-world study aimed to compare outcomes reached by lenvatinib and sorafenib second-line therapy in this setting., Methods: The overall cohort included 891 patients with HCC from 5 countries treated with atezolizumab plus bevacizumab in first-line setting between October 2018 and April 2022. At the data cut-off (May 2022), 41.5% of patients were continuing a first-line treatment, 5.5% were lost at follow-up, and 53.0% of patients had progressive disease after first-line therapy. 51.5% of patients with progressive disease received a second-line treatment, while 48.5% did not receive any subsequent therapy. Between patients receiving second-line treatment, 11.1% of patients underwent transarterial chemoembolization, 21.0% received sorafenib, 35.4% underwent lenvatinib, and 32.5% were treated with other drugs., Results: Lenvatinib second-line subgroup achieved a median overall survival (mOS) of 18.9 months, significative longer (p = 0.01; hazard ratio [HR]: 2.24) compared to sorafenib subgroup that reached a mOS of 14.3 months. The multivariate analysis highlighted albumin-bilirubin 1 grade (p < 0.01; HR: 5.23) and lenvatinib second-line therapy (p = 0.01; HR: 2.18) as positive prognostic factors for OS. The forest plot highlighted a positive trend in terms of OS in favor of patients treated with lenvatinib second-line regardless of baseline characteristics before first-line therapy., Conclusion: These results suggest that, in patients with HCC progressed to first-line atezolizumab plus bevacizumab, lenvatinib second-line therapy is associated to an improved survival compared to sorafenib., (© 2024 S.

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., (© 2023 S.

Introduction: The prognostic nutritional index (PNI) is a multiparametric score introduced by Onodera based on the blood levels of lymphocytes and albumin in patients with gastrointestinal neoplasms. Regarding hepatocellular carcinoma (HCC), its prognostic role has been shown in patients treated with sorafenib and lenvatinib. The aim of this real-world study was to investigate the association between clinical outcomes and PNI in patients being treated with atezolizumab plus bevacizumab., Methods: The overall cohort of this multicentric study included 871 consecutive HCC patients from 5 countries treated with atezolizumab plus bevacizumab in first-line therapy. The PNI was calculated as follows: 10 × serum albumin concentration (g/dL) + 0.005 × peripheral lymphocyte count (number/mm3)., Results: Data regarding lymphocyte counts and albumin levels were available for 773 patients; therefore, these patients were included in the final analysis. The cut-off point of the PNI was determined to be 41 by receiver operating characteristic analysis. 268 patients (34.7%) were categorized as the PNI-low group, while the remaining 505 (65.3%) patients as the PNI-high group. At the univariate analysis, high PNI was associated with longer overall survival (OS) (22.5 vs. 10.1 months, HR 0.34, p <0.01) and progression-free survival (PFS) (8.7 vs. 5.8 months, HR 0.63, p <0.01) compared to patients with low PNI. At the multivariate analysis, high versus low PNI resulted as an independent prognostic factor for OS (HR 0.49, p <0.01) and PFS (HR 0.82, p = 0.01). There was no difference in objective response rate between the two groups (high 26.1% vs. low 19.8%, p = 0.09), while disease control rate was significantly higher in the PNI-high group (76.8% vs. 66.4%, p = 0.01)., Conclusion: PNI is an independent prognostic factor for OS and PFS in HCC patients on first-line treatment with atezolizumab plus bevacizumab., (© 2023 S.

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., (© 2022 S.

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)., (© 2022 S.

Aim/background: Transarterial chemoembolization (TACE) is recommended for patients with intermediate-stage hepatocellular carcinoma (HCC). In this study, we investigated the impact of early lenvatinib administration in patients with intermediate-stage HCC, especially those with tumors beyond the up-to-7 criteria., Materials/methods: A total of 208 patients with intermediate-stage HCC whose initial treatment was early lenvatinib administration or TACE were enrolled. Multivariate overall survival analysis was performed in this cohort. In addition, the impact of early lenvatinib administration on survival in patients with HCC beyond the up-to-7 criteria was clarified using inverse probability weighting (IPW) analysis., Results: The overall cumulative survival rates at 6, 12, 18, and 24 months were 94.4, 79.9, 65.8, and 50.1%, respectively. Multivariate analysis with Cox proportional hazards modeling showed that HCC treatment with lenvatinib (hazard ratio [HR], 0.199; 95% confidence interval [CI], 0.077-0.517; p < 0.001), α-fetoprotein ≥100 ng/mL (HR, 1.687), Child-Pugh class B disease (HR, 1.825), and beyond the up-to-7 criteria (HR, 2.016) were independently associated with overall survival. The 6-, 12-, 18-, and 24-month cumulative survival rates were 96.0, 90.4, 65.7, and 65.7%, respectively, in patients treated with lenvatinib, and 94.1, 78.5, 65.3, and 48.4%, respectively, in patients who received TACE (p < 0.001). In addition, univariate analysis with Cox proportional hazards modeling adjusted by IPW showed that lenvatinib therapy was significantly associated with overall survival in patients with HCC beyond the up-to-7 criteria (HR, 0.230; 95% CI, 0.059-0.904; p = 0.035)., Conclusions: Lenvatinib may be a suitable first-line treatment for patients with intermediate-stage HCC beyond the up-to-7 criteria., (© 2021 S.
