α-FAtE: A new predictive score of response to atezolizumab plus bevacizumab for unresectable hepatocellular carcinoma.

Atezolizumab plus bevacizumab (AB) and lenvatinib can be alternatively used as first-line systemic treatment of unresectable hepatocellular carcinoma (HCC). However, no direct comparison of the two regimens has been performed in randomized clinical trials, making the identification of baseline differential predictors of response of major relevance to tailor the best therapeutic option to each patient. Baseline clinical and laboratory characteristics of real-world AB-treated HCC patients were analyzed in uni- and multivariate analyses to find potential prognostic factors of overall survival (OS). Significant variables were incorporated in a composite score (α-FAtE) and it was tested for specificity and sensitivity in receiver operating characteristic (ROC) curve and in multivariate analysis for OS. The score was applied in uni- and multivariate analyses for OS of a comparable lenvatinib-treated HCC population. Finally, comparison between treatments was performed in patients with low and high α-FAtE scores and predictivity estimated by interaction analysis. Time-to-progression (TTP) was a secondary endpoint. OS of AB-treated HCC patients was statistically longer in those with α-fetoprotein <400 ng/mL (HR 0.62, p = .0407), alkaline phosphatase (ALP) <125 IU/L (HR 0.52, p = .0189) and eosinophil count ≥70/µL (HR 0.46, p = .0013). The α-FAtE score was generated by the sum of single points attributed to each variable among the above reported. In ROC curve analysis, superior sensitivity and specificity were achieved by the score compared to individual variables (AUC 0.794, p < .02). Patients with high score had longer OS (HR 0.44, p = .0009) and TTP (HR 0.34, p < .0001) compared to low score if treated with AB, but not with lenvatinib. Overall, AB was superior to lenvatinib in high score patients (HR 0.55, p = .0043) and inferior in low score ones (HR 1.75, p = .0227). At interaction test, low α-FAtE score resulted as negative predictive factor of response to AB (p = .0004). In conclusion, α-FAtE is a novel prognostic and predictive score of response to first-line AB for HCC patients that, if validated in prospective studies, could drive therapeutic choice between lenvatinib and AB.

Dose-reduction of bevacizumab in atezolizumab plus bevacizumab therapy extends treatment duration with disease control in patients with hepatocellular carcinoma.

INTRODUCTION: Atezolizumab (ATZ) and bevacizumab (BEV) combination therapy is widely used in patients with unresectable hepatocellular carcinoma (HCC). However, combination therapy is typically interrupted or discontinued owing to BEV-related adverse events. In this study, we examined the effects of BEV dose-reduction on the treatment of unresectable HCC using propensity score matching (PSM). METHOD: Overall, 119 patients with HCC who were treated with ATZ + BEV between November 2020 and October 2022 were enrolled retrospectively at our institute. The therapeutic effects and safety of BEV dose-reduction and non-dose reduction after PSM were compared. Decision-tree analysis was used to investigate treatment duration in the patients. RESULTS: Significant differences were not observed between the two groups after PSM. The objective response rate (ORR) and disease control rate (DCR) assessed by modified RECIST did not differ significantly between the two groups (BEV non-dose-reduction/dose-reduction: ORR; 46/34%, DCR; 80/91%). Progression-free survival (PFS) and overall survival (OS) also did not differ significantly between the two groups (BEV non-dose-reduction /dose-reduction: PFS; 5.6/8.6 months, OS; 18.6/15.5 months). The median duration of treatment in the BEV dose-reduction group was significantly longer than that in the non-dose-reduction group (BEV non-dose-reduction /dose-reduction: 4.8/9.1 months, P = 0.038). Decision-tree analysis revealed that dose-reduction of BEV was the first distinguishae factor for the extension of treatment duration with ATZ + BEV. CONCLUSION: BEV dose-reduction can be effectively used in maintaining the treatment duration of ATZ + BEV while maintaining therapeutic effects and safety in real-world clinical practice.

Impact of body mass index on the prognosis of unresectable HCC patients receiving first-line Lenvatinib or atezolizumab plus bevacizumab.

INTRODUCTION: Overweight is a negative prognostic factor in the general population in the long term. However, the role of body mass index (BMI) in the short-mid term in advanced tumours is unclear. The present analysis investigates the role of BMI weight classes in a large sample of patients affected by HCC and receiving atezolizumab plus bevacizumab or lenvatinib as first-line treatment. METHODS AND MATERIAL: The cohort included consecutive patients affected by BCLC-c and BCLC-B HCC patients from a multicenter international study group who received atezolizumab plus bevacizumab or lenvatinib as first-line therapy. Population was stratified according to the BMI in under-, over- and normal-weight according to the conventional thresholds. The primary objective of the study was to evaluate the prognostic and predictive impact of BMI in patients affected by advanced or intermediate HCC. Survival curves were estimated using the product-limit method of Kaplan-Meier. The role of stratification factors was analysed with log-rank tests. RESULTS: 1292 consecutive patients with HCC were analysed. 466 (36%) patients were treated with lenvatinib and 826 (64%) patients were treated with atezolizumab plus bevacizumab. In the atezolizumab plus bevacizumab arm, 510 (62%) patients were normal-weight, 52 (6%) underweight and 264 (32%) overweight. At the univariate analysis for OS, underweight patients had significantly shorter OS compared to normal-weight patients, whereas no differences were found between normal-weight versus overweight. Multivariate analysis confirmed that underweight patients had significantly shorter OS compared to normal-weight patients (HR: 1.7; 95% CI: 1.0-2.8; p = .0323). In the lenvatinib arm, 26 patients (5.6%) were categorized as underweight, 256 (54.9%) as normal-weight, and 184 (39.5%) as overweight. At the univariate analysis for OS, no significant differences were found between normal-weight versus underweight and between normal-weight versus overweight, which was confirmed at multivariate analysis. CONCLUSION: Our analysis highlighted a prognostic role of BMI in a cohort of patients with advanced HCC who received atezolizumab plus bevacizumab, while no prognostic role for low BMI was apparent in patients who received lenvatinib.

Evaluation of the associations of interlukin-7 genetic variants with toxicity and efficacy of immune checkpoint inhibitors: A replication study of a Japanese population, based on the findings of a European genome-wide association study.

AIM: Recent genome-wide association studies of European populations have identified rs16906115, a single-nucleotide polymorphism in the interleukin-7 gene, as a predictor of immune-related adverse events (irAEs) and the therapeutic efficacy of immune checkpoint inhibitors. We evaluated this single-nucleotide polymorphism in a Japanese population. METHODS: From January 2021, we stored host DNA from individuals who received various types of immune checkpoint inhibitors. From this population, we categorized 510 participants into cases (grade ≥2 irAEs) and controls (received ≥3 immune checkpoint inhibitor doses, follow-up ≥12 weeks, no irAEs), and divided 339 hepatocellular carcinoma patients treated with atezolizumab/bevacizumab into responders and non-responders, evaluated using the modified response evaluation criteria in solid tumors. We compared the minor allele frequencies of rs16906115 between cases and controls, and responders and non-responders. RESULTS: In the irAE prediction analysis of 234 cases and 276 controls, the minor allele frequency was 0.244 in the case group and 0.265 in the control group. This difference is not significant. In the analysis predicting the therapeutic efficacy for hepatocellular carcinoma patients, the responders had a significantly lower minor allele frequency of 0.220, compared with 0.300 for the non-responders (p = 0.022). Univariate and multivariate analyses identified the minor allele homozygosity as a significant predictor of treatment response, with odds ratios of 0.292 (p = 0.015) in the univariate analysis and 0.315 (p = 0.023) in the multivariate analysis. CONCLUSIONS: In our Japanese cohort, no association was found between the rs16906115 minor allele and irAEs or treatment efficacy. The minor allele homozygosity may be associated with a negative therapeutic outcome. CLINICAL TRIAL REGISTRATION: UMIN Clinical Trials Registry with the number UMIN000043798.

Role of the Prognostic Nutritional Index in Predicting Survival in Advanced Hepatocellular Carcinoma Treated with Atezolizumab Plus Bevacizumab.

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.

Significance of ramucirumab following atezolizumab plus bevacizumab therapy for hepatocellular carcinoma using real-world data.

AIM: Few studies have reported the efficacy and safety of ramucirumab (RAM) after atezolizumab plus bevacizumab (Atezo/Beva) treatment and the overall associated outcomes. Thus, we aimed to evaluate the therapeutic effects and safety of RAM post-treatment with Atezo/Beva. METHODS: This retrospective study enrolled 46 patients with unresectable hepatocellular carcinoma who were treated with RAM. The patients were classified into the RAM administered following Atezo/Beva failure (n = 12) or RAM administered following other drug failure (n = 34) groups. Progression-free survival (PFS), overall survival (OS), and adverse event (AE) rates were assessed. RESULTS: There were significant differences in the objective response rates and disease control rates between the RAM administered following Atezo/Beva and RAM administered following others groups (objective response rate 33.3%. vs. 0.0%, p = 0.001; disease control rate 83.3% vs. 32.3, p = 0.001). Although there was no significant difference in the OS rates, the median PFS rates in the RAM administered following Atezo/Beva group was significantly higher than in the RAM administered following others group (PFS 3.9 months. vs. 1.9 months, p = 0.047). The AE rates were comparable between the two groups; ascites was the most common AE (45.6%). Using decision tree analysis, the presence of splenomegaly and body mass index (BMI) < 19.8 were the first and second splitting variables for RAM-related ascites, respectively. CONCLUSIONS: The therapeutic effect of RAM increased in patients with Atezo/Beva failure. Patients with splenomegaly and low BMI should be monitored for ascites during RAM treatment.

The beneficial impact of metabolic dysfunction-associated fatty liver disease on lenvatinib treatment in patients with non-viral hepatocellular carcinoma.

AIM: Lenvatinib is used to treat advanced hepatocellular carcinoma (HCC). Metabolic dysfunction-associated fatty liver disease (MAFLD) is becoming a major etiology of HCC. We aimed to evaluate the impact of MAFLD on the efficacy of lenvatinib. METHODS: We enrolled 320 patients with HCC who were treated with lenvatinib. All patients were classified into the MAFLD (n = 155) and non-MAFLD (n = 165) groups. Independent factors for overall survival (OS) were analyzed. In the stratification analysis, HCC was categorized as non-viral (n = 115) or viral HCC (n = 205). RESULTS: The OS rate was significantly higher in the MAFLD group than in the non-MAFLD group (median 21.1 vs. 15.1 months, p = 0.002). Multivariate analysis demonstrated that, in addition to albumin-bilirubin grade and Barcelona Clinic Liver Cancer stage, MAFLD was identified as an independent factor for OS (HR 0.722, 95% CI 0.539-0.966, p = 0.028). In the stratification analysis, the OS rate was significantly higher in the MAFLD group than in the non-MAFLD group among patients with non-viral HCC (median 21.1 vs. 15.1 months, p = 0.002), but not in patients with viral HCC. Furthermore, MAFLD was an independent negative risk factor for OS in patients with non-viral HCC (HR 0.506, 95% CI 0.297-0.864, P < 0.01). However, MAFLD was not an independent factor for OS in patients with viral HCC. CONCLUSIONS: MAFLD was a beneficial factor for survival in patients with HCC treated with lenvatinib. Moreover, the better OS of the MAFLD group was more pronounced in patients with non-viral HCC. Lenvatinib may be a suitable agent for patients with non-viral HCC and MAFLD.

Telephone follow-up contributes to improving adherence and treatment duration in patients with hepatocellular carcinoma treated with lenvatinib.

BACKGROUND AND AIM: This study aimed to investigate whether telephone follow-up by clinical pharmacists for unresectable hepatocellular carcinoma (HCC) patients treated with lenvatinib (LEN) contributes to improved adherence and treatment duration for LEN. METHODS: This retrospective study enrolled 132 patients with HCC who were treated with LEN. The patients were classified into non-telephone follow-up (n = 32) or telephone follow-up groups (n = 100) [the latter group was further classified into family-pharmacist (FP) telephone follow-up (n = 18), or hospital family-pharmacist (HFP) telephone follow-up (n = 82) groups]. RESULTS: The progression-free survival (PFS) in the telephone follow-up group was significantly higher than that in the non-telephone follow-up group (PFS 6.1 months vs 3.7 months, P = 0.001, respectively). Although treatment duration was significantly longer in the telephone follow-up group than in the non-telephone follow-up group [median treatment duration: 10.4 months vs 4.1 months, P = 0.001, respectively.], no significant differences were noted between the HFP telephone follow-up group and FP telephone follow-up groups (10.3 months vs 13.3 months, P = 0.543). Self-interruption and adverse-event discontinuation in the HFP-telephone follow-up group were significantly lower than those in the FP-telephone and non-telephone groups (0% vs 11.1% vs 18.8%; P < 0.001, 25.6% vs 33.3% vs 53.1%; P = 0.022, respectively). CONCLUSIONS: Telephone follow-up contributes to prolonged treatment duration for LEN in patients with HCC treated. Moreover, telephone follow-up with an HFP may further improve treatment adherence.

Efficacy of Lenvatinib Combined with Transcatheter Intra-Arterial Therapies for Patients with Advanced-Stage of Hepatocellular Carcinoma: A Propensity Score Matching.

This study aimed to evaluate the effect of lenvatinib (LEN) combined with transcatheter intra-arterial therapy (TIT) for advanced-stage hepatocellular carcinoma (HCC) after propensity score matching (PSM). This retrospective study enrolled 115 patients with advanced-stage HCC who received LEN treatment. The patients were categorized into the LEN combined with TIT group (n = 30) or the LEN monotherapy group (n = 85). After PSM, 38 patients (LEN + TIT group, n = 19; LEN monotherapy group, n = 19) were analyzed. The median overall survival (OS) in the LEN + TIT group was significantly higher than that in the LEN monotherapy group (median survival time (MST): 28.1 months vs. 11.6 months, p = 0.014). The OS in the LEN combined with transcatheter arterial chemoembolization and LEN combined with hepatic arterial infusion chemotherapy groups was significantly higher than that in the LEN monotherapy group (MST 20.0 vs. 11.6 months, 30.2 vs. 11.6 months, p = 0.048, and p = 0.029, respectively). Independent factors associated with OS were alpha-fetoprotein and LEN combined with TIT. The indications for LEN combined with TIT were age <75 years and modified albumin bilirubin (m-ALBI) grade 1. We concluded that LEN combined with TIT may improve prognosis compared with LEN monotherapy in patients with advanced-stage HCC.

[Minimally Invasive Conversion Hepatectomy for Advanced Hepatocellular Carcinoma].

Some cases of advanced hepatocellular carcinoma(HCC)diagnosed as unresectable(UR)have been reported to undergo conversion surgery following systemic therapy. Furthermore, the combination of atezolizumab plus bevacizumab(Atez/Bev) shows potential therapeutic effects in conversion surgery for UR-HCC. At our hospital, neoadjuvant chemotherapy(NAC) using New-FP therapy(hepatic arterial infusion chemotherapy: HAIC)has been performed for borderline resectable HCC. New-FP therapy for advanced HCC with macrovascular invasion has a high response rate of 70%. For hepatectomy after NAC, a high response rate is required as a pretreatment, and New-FP therapy may be useful as the initial treatment. Limited reports exist of the laparoscopic approach in conversion surgery for advanced HCC. However, 14 cases of minimally invasive liver resection, including 10 cases after New-FP therapy and 4 cases after Atez/Bev therapy, have been safely performed conversion surgery for advanced HCC. In selected patients with advanced HCC, minimally invasive liver resection may be safely performed if the tumor shows shrinkage with various treatments.

[A case of difficult treatment of infected pseudoaneurysm of the femoral artery during hepatic arterial infusion chemotherapy for hepatocellular carcinoma].

For advanced hepatocellular carcinoma, an 80's woman underwent right inguinal reservoir port implantation and hepatic arterial infusion chemotherapy. The patient developed sepsis caused by methicillin-resistant Staphylococcus aureus 40 days after starting treatment. After the reservoir port was removed, an infected pseudoaneurysm developed. Interventional radiology treatment could not be completed because of the shape of the aneurysm, and deep femoral artery suture closure was conducted surgically. Unfortunately, the pseudoaneurysm recurred two months after surgery, and treatment for hepatocellular carcinoma was discontinued. It is important to remember that the formation of pseudoaneurysms is a complication after reservoir port placement.

Validation of the easy-to-use lenvatinib prognostic index to predict prognosis in advanced hepatocellular carcinoma patients treated with lenvatinib.

AIM: The identification of new prognostic factors able to stratify hepatocellular carcinoma patients candidate to first-line therapy is urgent. In the present work we validated the prognostic value of the lenvatinib prognostic index. METHODS: Data of Eastern and Western patients treated with lenvatinib as first-line for Barcelona Clinic Liver Cancer stage B or C hepatocellular carcinoma were recollected. The lenvatinib prognostic index was composed by three classes of risk according with our previous study. The "low risk" group includes patients with prognostic nutritional index (PNI) >43.3 and with previous transarterial chemoembolization. The "medium risk" group includes patients with PNI >43.3, but without previous transarterial chemoembolization and patients with PNI <43.3, albumin-bilirubin grade 1 and Barcelona Clinic Liver Cancer stage B. The "high risk" group includes patients with PNI <43.3, albumin-bilirubin grade 2, and patients with PNI <43.3, albumin-bilirubin grade 1 and Barcelona Clinic Liver Cancer stage C. RESULTS: A total of 717 patients were included. The median overall survival was 20.7 months (95% CI 16.1-51.6) in patients with low risk (n = 223), 16.7 months (95% CI 13.3-47.0) in patients with medium risk (n = 264), and 10.7 months (95% CI 9.3-12.2) in patients with high risk (n = 230; HR 1, 1.29, and 1.92, respectively; p < 0.0001). Median progression-free survival was 7.3 months (95% CI 6.3-46.5) in patients with low risk, 6.4 months (95% CI 5.3-8.0) in patients with medium risk ,and 4.9 months (95% CI 4.3-5.5) in patients with high risk (HR 1, 1.07, 1.47 respectively; p = 0.0009). CONCLUSION: The lenvatinib prognostic index confirms its prognostic value on an external cohort of hepatocellular carcinoma patients treated with Lenvatinib.

Multimolecular-Targeted Agents for Intermediate-Stage Hepatocellular Carcinoma Influence Time to Stage Progression and Overall Survival.

Background & Aims: Intermediate hepatocellular carcinoma (HCC) treatment has become complicated due to the development of various molecular-targeted agents (MTAs). We aimed to determine whether the administration of MTAs in patients with intermediate-stage HCC contributed to the prevention of progression to an advanced stage. METHODS: We enrolled and retrospectively examined 289 patients with Child-Pugh class A who had been diagnosed with intermediate-stage HCC and underwent initial trans-arterial chemoembolization (TACE). Patients were classified into 2 groups: a group in which MTAs were administered to patients whose condition was refractory to TACE (n = 65) and a group in which MTAs were not administered (n = 65) at intermediate-stage HCC after propensity score matching (PSM). Time to stage progression (TTSP) and overall survival (OS) were calculated using the Kaplan-Meier method and analyzed using a log-rank test after PSM. RESULTS: TTSP and OS of the group with MTA administration were significantly longer than those of the group without MTA administration (TTSP: 36.4 vs. 17.9 months, p < 0.001; median survival time [MST]: 44.6 vs. 26.6 months, p = 0.001). Within the up-to-seven criteria and administration of MTAs at the intermediate-stage HCC were identified as independent factors for TTSP and OS in the multivariate analysis. TTSP and OS in the era of the multi-MTA group were significantly longer than those in the era of the mono-MTA group (TTSP: 44.8 vs. 27.4 months, p = 0.01; MST: 53.4 vs. 33.3 months, p = 0.01). CONCLUSION: The administration of MTAs in patients with intermediate-stage HCC contributes to the prevention of stage progression and prolongs OS.

Lenvatinib versus sorafenib in first-line treatment of unresectable hepatocellular carcinoma: An inverse probability of treatment weighting analysis.

PURPOSE: Data from common clinical practice were used to generate balanced cohorts of patients receiving either sorafenib or lenvatinib, for unresectable hepatocellular carcinoma, with the final aim to investigate their declared equivalence. METHODS: Clinical features of lenvatinib and sorafenib patients were balanced through inverse probability of treatment weighting (IPTW) methodology, which weights patients' characteristics and measured outcomes of each patient in both treatment arms. Overall survival was the primary endpoint and occurrence of adverse events was the secondary. RESULTS: The analysis included 385 patients who received lenvatinib, and 555 patients who received sorafenib. In the unadjusted cohort, lenvatinib did not show a survival advantage over sorafenib (HR: 0.85, 95% CI 0.70-1.02). After IPTW adjustment, lenvatinib still not returned a survival advantage over sorafenib (HR: 0.82, 95% CI: 0.62-1.07) even in presence of balanced baseline characteristics. Lenvatinib provided longer survival than sorafenib in patients previously submitted to TACE (HR: 0.69), with PS of 0 (HR: 0.73) or without extrahepatic disease (HR: 0.69). CONCLUSION: Present results confirmed randomized controlled trial in the real-life setting, but also suggests that in earlier stages some benefit can be expected.

Adverse events as potential predictive factors of activity in patients with advanced hepatocellular carcinoma treated with lenvatinib.

BACKGROUND AND AIM: Lenvatinib is a standard of care option in first-line therapy of advanced hepatocellular carcinoma (HCC). In the present study, we aim to identify, in patients with HCC treated with lenvatinib, a possible association between occurrence and grading of adverse events (AEs) and outcome. METHODS: We performed a retrospective analysis of 606 Japanese and Italian patients treated with lenvatinib in first-line setting and investigated the possible correlation between the onset of AEs, toxicity grade (G) and outcome measures such as overall survival (OS) and progression-free survival (PFS). RESULTS: The appearance of arterial hypertension G ≥ 2 independently predicted prolonged OS [hazard ratio (HR) 0.66, 95% confidence interval (CI) 0.46-0.93, P = .0188], whereas decreased appetite G ≥ 2 independently predicted decreased OS (HR 1.70, 95% CI 1.25-2.32, P = .0007) by multivariate analysis. Appearance of hand-foot skin reaction independently predicted prolonged PFS (HR 0.72, 95% CI 0.56-0.93, P = .0149), whereas decreased appetite G ≥ 2 predicted decreased PFS (HR 1.36, 95% CI 1.04-1.77, P = .0277). CONCLUSIONS: Our main findings are that the occurrence of arterial hypertension G ≥ 2 is a predictor of longer survival, whereas decreased appetite G ≥ 2 predicts for a poor prognosis. A careful management of AEs under lenvatinib treatment for HCC is required, to improve patients' quality of life, minimize the need for treatment discontinuation and achieve optimal outcome.

Lenvatinib versus Sorafenib as first-line treatment in hepatocellular carcinoma: A multi-institutional matched case-control study.

BACKGROUND: Advanced Hepatocarcinoma (HCC) is an important health problem worldwide. Recently, the REFLECT trial demonstrated the non-inferiority of Lenvatinib compared to Sorafenib in I line setting, thus leading to the approval of new first-line standard of care, along with Sorafenib. AIMS AND METHODS: With aim to evaluate the optimal choice between Sorafenib and Lenvatinib as primary treatment in clinical practice, we performed a multicentric analysis with the propensity score matching on 184 HCC patients. RESULTS: The median overall survival (OS) were 15.2 and 10.5 months for Lenvatinib and Sorafenib arm, respectively. The median progression-free survival (PFS) was 7.0 and 4.5 months for Lenvatinib and Sorafenib arm, respectively. Patients treated with Lenvatinib showed a 36% reduction of death risk (p = 0.0156), a 29% reduction of progression risk (p = 0.0446), a higher response rate (p < 0.00001) and a higher disease control rate (p = 0.002). Sorafenib showed to be correlated with more hand-foot skin reaction and Lenvatinib with more hypertension and fatigue. We highlighted the prognostic role of Barcelona Clinic Liver Cancer (BCLC) stage, Eastern Cooperative Oncology Group Performance Status (ECOG-PS), bilirubin, alkaline phosphatase and eosinophils for Sorafenib. Conversely, albumin, aspartate aminotransferase (AST), alkaline phosphatase and Neutrophil-Lymphocyte Ratio (NLR) resulted prognostic in Lenvatinib arm. Finally, we highlighted the positive predictive role of albumin > Normal Value (NV), ECOG > 0, NLR < 3, absence of Hepatitis C Virus positivity, and presence of portal vein thrombosis in favor of Lenvatinib arm. Eosinophil < 50 and ECOG > 0 negatively predicted the response to Sorafenib. CONCLUSION: SLenvatinib showed to better perform in a real-word setting compared to Sorafenib. More researches are needed to validate the predictor factors of response to Lenvatinib rather than Sorafenib.

Increased Arterio-Portal Shunt Formation after Drug-Eluting Beads TACE for Hepatocellular Carcinoma.

BACKGROUND AND AIMS: Conventional transcatheter arterial chemoembolization (C-TACE) and drug-eluting bead (DEB)-based TACE are current treatments for hepatocellular carcinoma (HCC). We compared the therapeutic efficacies and adverse events of these methods in a single-center retrospective cohort study. METHODS: We enrolled 174 patients treated between January 2010 and October 2016; 98 and 76 underwent C-TACE and DEB-TACE, respectively, with 76 and 22 of the former group and 49 and 27 of the latter group classified as Child-Pugh class A and B, respectively. Therapeutic outcomes, progression-free survival (PFS), and adverse events were evaluated. RESULTS: The PFS rates in the C-TACE and DEB-TACE groups were 8.1 and 6.1 months, respectively (p = 0.79). The response and disease control rates were 64 and 71% in C-TACE patients and 69 and 78% in DEB-TACE patients, respectively (p = 0.25). Postprocedural pain, vomiting, and fever were more frequent following C-TACE than DEB-TACE (p < 0.001). In contrast, the incidences of bilomas and arterio-portal shunts were significantly higher following DEB-TACE (p < 0.001); the incident rates of arterio-portal shunt formation were 8.1 and 48.7% in patients undergoing C-TACE and DEB-TACE, respectively. Child-Pugh class A was significantly associated with arterio-portal shunt formation after DEB-TACE on multivariate analysis. CONCLUSIONS: There were no significant differences in the therapeutic efficacies of C-TACE and DEB-TACE. However, the frequency of arterio-portal shunt formation was significantly higher in HCC patients with Child-Pugh class A undergoing DEB-TACE. Our findings imply that C-TACE should be selected for HCC patients with Child-Pugh class A and DEB-TACE should be chosen for those with Child-Pugh class B.

Dose and Location of Irradiation Determine Survival for Patients with Hepatocellular Carcinoma with Macrovascular Invasion in External Beam Radiation Therapy.

AIM: Prognosis of hepatocellular carcinoma (HCC) with macrovascular invasion (MVI) is extremely poor. However, proper therapeutic strategies have not been established yet. The purpose of this study is to identify the effects of external beam radiation therapy (EBRT) for MVI of HCC. METHODS: We have analyzed and evaluated 80 consecutive patients with HCC with MVI who underwent EBRT, and factors associated with enhanced survival in EBRT were evaluated by univariate and multivariate analysis. RESULTS: The local response rate of radiotherapy for the irradiated MVI was 66.2%. The time to progression of the irradiated MVI was 5.8 months. Univariate and multivariate analyses showed that the higher irradiation dose (over 45 Gy) and the irradiation location (hepatic vein tumor thrombus - HVTT) were significant factors associated with survival benefits of EBRT. The response of EBRT for HVTT was significantly superior to that for portal vein or bile duct tumor thrombus. CONCLUSION: We conclude that a multidisciplinary therapeutic strategy based on EBRT should be proactively selected in the treatment of advanced HCC with MVI.

Epirubicin is More Effective than Miriplatin in Balloon-Occluded Transcatheter Arterial Chemoembolization for Hepatocellular Carcinoma.

BACKGROUND: Transcatheter arterial chemoembolization (TACE) is a standard therapy used in the treatment of intermediate hepatocellular carcinoma (HCC). Recently, balloon-occluded TACE (B-TACE) has been developed. PURPOSE: This study aimed to clarify the effects of B-TACE in patients with HCC, with a focus on which drug is suitable to suspend in Lipiodol for B-TACE. METHODS: We retrospectively evaluated 35 patients with HCC treated with B-TACE. Factors associated with enhanced time to progression (TTP) after B-TACE were evaluated using univariate and multivariate analyses. RESULTS: A total of 35 patients with HCC (40 nodules) were treated with B-TACE between June 2013 and August 2016. Epirubicin was used in 25 nodules and miriplatin was used in 15 nodules. Epirubicin (15.1 months) was significantly better than miriplatin (3.2 months) in prolonging the local TTP after B-TACE (p = 0.0293). Epirubicin showed a positive tendency in TE4 (100% tumor necrosis) rate when compared with miriplatin (p = 0.058). Achievement of TE4 was the only significant factor associated with better TTP after B-TACE. Epirubicin- and TACE-naïve statuses were significant factors in achieving TE4 with B-TACE. CONCLUSION: To enhance the TTP with B-TACE, TE4 should be achieved. Epirubicin is a more optimal anticancer drug (as a Lipiodol suspension) than miriplatin for achieving TE4 with B-TACE.

Spontaneous regression of hepatocellular carcinoma with reduction in angiogenesis-related cytokines after treatment with sodium-glucose cotransporter 2 inhibitor in a cirrhotic patient with diabetes mellitus.

Spontaneous regression of hepatocellular carcinoma (HCC) is a rare event, and the pathogenesis remains unclear. Here, we present a case of spontaneous regression of HCC after treatment with sodium-glucose cotransporter 2 inhibitor (SGLT2i) in a cirrhotic patient with diabetes mellitus (DM). A 68-year-old man regularly visited our hospital for follow-up of HCC after treatment with transcatheter arterial chemoembolization, and management of liver cirrhosis and type 2 DM. Contrast-enhanced computed tomography scan showed a hypervascular tumor in the liver and elevated serum α-fetoprotein levels, indicating the recurrence of HCC. Simultaneously, the hemoglobin A1c value increased to 8.0%; therefore, he was treated with SGLT2i (canagliflozin 100 mg/day). Ten weeks after the initiation of SGLT2i treatment, he was admitted to our hospital for treatment of recurrent HCC. However, the hypervascular tumor had disappeared, and the elevated serum α-fetoprotein level had decreased to normal limits, indicating spontaneous regression of HCC. In addition, an angiogenesis array analysis revealed downregulated protein expression of matrix metalloproteinase-8, angiopoietin-1/2, platelet-derived growth factor-AA, and prolactin at 10 weeks after SGLT2i treatment. In this report, we first describe a case of spontaneous regression of HCC with reduction in angiogenesis-related cytokines after SGLT2i treatment.
