Sequential therapies after atezolizumab plus bevacizumab or lenvatinib first-line treatments in hepatocellular carcinoma patients.

INTRODUCTION: The aim of this retrospective proof-of-concept study was to compare different second-line treatments for patients with hepatocellular carcinoma and progressive disease (PD) after first-line lenvatinib or atezolizumab plus bevacizumab. MATERIALS AND METHODS: A total of 1381 patients had PD at first-line therapy. 917 patients received lenvatinib as first-line treatment, and 464 patients atezolizumab plus bevacizumab as first-line. RESULTS: 49.6% of PD patients received a second-line therapy without any statistical difference in overall survival (OS) between lenvatinib (20.6months) and atezolizumab plus bevacizumab first-line (15.7months; p = 0.12; hazard ratio [HR]= 0.80). After lenvatinib first-line, there wasn't any statistical difference between second-line therapy subgroups (p = 0.27; sorafenib HR: 1; immunotherapy HR: 0.69; other therapies HR: 0.85). Patients who underwent trans-arterial chemo-embolization (TACE) had a significative longer OS than patients who received sorafenib (24.7 versus 15.8months, p < 0.01; HR=0.64). After atezolizumab plus bevacizumab first-line, there was a statistical difference between second-line therapy subgroups (p < 0.01; sorafenib HR: 1; lenvatinib HR: 0.50; cabozantinib HR: 1.29; other therapies HR: 0.54). Patients who received lenvatinib (17.0months) and those who underwent TACE (15.9months) had a significative longer OS than patients treated with sorafenib (14.2months; respectively, p = 0.01; HR=0.45, and p < 0.05; HR=0.46). CONCLUSION: Approximately half of patients receiving first-line lenvatinib or atezolizumab plus bevacizumab access second-line treatment. Our data suggest that in patients progressed to atezolizumab plus bevacizumab, the systemic therapy able to achieve the longest survival is lenvatinib, while in patients progressed to lenvatinib, the systemic therapy able to achieve the longest survival is immunotherapy.

Easy clinical predictor for low BCAA to tyrosine ratio in chronic liver disease patients with hepatocellular carcinoma: Usefulness of ALBI score as nutritional prognostic marker.

BACKGROUND/AIM: Low branched-chain amino acid (BCAA) to tyrosine ratio (BTR) is known as an indicator of amino acid imbalance. We elucidated usefulness of newly developed albumin-bilirubin (ALBI) score as alternative methods of BTR in patients with naïve hepatocellular carcinoma (HCC) retrospectively. MATERIALS/METHODS: In 842 patients with HCC and without BCAA supplementation (71 years, male 614, Child-Pugh A:B:C = 689:116:37), relationships among BTR and clinical features were evaluated. Of those, 438 patients, with Milan criteria HCC, treated curatively were divided into the high-BTR (>4.4) (n = 293) and low-BTR (≤4.4) (n = 145) groups. The prognostic value of BTR was evaluated using inverse probability weighting (IPW) with propensity score. RESULTS: The low-BTR group showed worse prognosis than the other (3-, 5-, 10-year overall survival rates: 88.9% vs. 86.3%/70.5% vs. 78.1%/38.1% vs. 52.3%, respectively; p < 0.001). Multivariate Cox-hazard analysis adjusted for IPW showed elderly (≥65 years) HR 2.314, p = 0.001), female gender (HR 0.422, p < 0.001), ECOG PS ≥2 (HR 3.032, p = 0.002), low platelet count (HR 1.757, p = 0.010), and low BTR (≤4.4) (HR 1.852, p = 0.005) to be significant prognostic factors. Both serum albumin level (r = 0.370, p < 0.001) and ALBI score (r = -0.389, p < 0.001) showed a significant relationship with BTR. Child-Pugh class B, modified ALBI grade (mALBI) 2a, and mALBI 2b predictive values for BTR were 3.589, 4.509, and 4.155 (AUC range: 0.735-0.770), respectively, while the predictive value of ALBI score for low-BTR (≤4.4) was -2.588 (AUC 0.790). CONCLUSION: ALBI score -2.588 was a predictor for low-BTR (≤4.4), which was prognostic factors for early HCC patients, and at least patients with mALBI 2b might have an amino acid imbalance.

Nutritional Index as Prognostic Indicator in Patients Receiving Lenvatinib Treatment for Unresectable Hepatocellular Carcinoma.

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.

Can L-carnitine supplementation and exercise improve muscle complications in patients with liver cirrhosis who receive branched-chain amino acid supplementation?

BACKGROUND: The aim of this study was to elucidate the efficacy of the combination of L-carnitine and exercise, reported to prevent muscle wasting, for muscle complications (function, volume, and cramping) in patients with liver cirrhosis (LC) who received branched-chain amino acid supplementation. MATERIALS AND METHODS: From December 2017 to April 2018, 18 patients with LC who had been given branched-chain amino acid granule supplementation (12.45 g/day) were enrolled (mean age 68.4±10.8 years; 10 males and eight females; Child-Pugh A : B=9 : 9). After evaluating the average number of daily steps, oral L-carnitine supplementation (1000 mg/day) and additional exercise (plus 2000 steps/day) were added for 6 months. Every 4 weeks, a pedometer, a hand dynamometer, ergometer, and bioelectrical impedance analysis were used to evaluate daily steps, muscle function and muscle volume, and muscle cramps were recorded using a numerical rating scale. RESULTS: Average steps and serum levels of total and free carnitine were increased from before treatment to the final measurement (1883.5±1211.6 vs. 3165.1±1800.0/day, 62.6±16.5 vs. 110.9±28.6 µmol/l, and 47.7±15.2 vs. 83.2±21.5 µmol/l, respectively; P<0.01), whereas there were no significant changes in the ratios of handgrip strength, leg strength, and muscle volume after 6 months [1.00±0.13 (P=0.991), 1.07±0.13 (P=0.073), and 0.992±0.036 (P=0.390), respectively]. However, the frequency of complaints of muscle cramping was reduced as compared with the start of therapy (baseline, 3 months, and 6 months: 6.3±4.8, 3.1±3.3, and 2.1±2.0, respectively) (P=0.025, Holm's method), whereas numerical rating scale did not show any significant improvement. CONCLUSION: L-Carnitine may have an important role for prevention of muscle wasting and reducing the frequency of muscle cramping.

Impact of albumin-bilirubin grade on survival in patients with hepatocellular carcinoma who received sorafenib: An analysis using time-dependent receiver operating characteristic.

BACKGROUND AND AIM: Albumin-bilirubin (ALBI) grade was developed as a new method to assess hepatic function. Sorafenib has been confirmed to be effective in improving survival in patients with advanced hepatocellular carcinoma (HCC). In this study, we investigated the impact of ALBI grade versus Child-Pugh classification on survival in HCC patients who received sorafenib. METHODS: A total of 567 patients with advanced HCC who received sorafenib were included. We analyzed survival based on Child-Pugh classification or score and ALBI grade or score. We also compared the ability of ALBI and Child-Pugh scores to predict survival using time-dependent receiver operating characteristic analysis. RESULTS: Cumulative survival rates at 90, 180, 360, and 720 days were 84.1%, 66.6%, 47.0%, and 23.3%, respectively. Median survival was 316 days (95% confidence interval, 279-377). Both Child-Pugh classification and ALBI grade were independently associated with overall survival in multivariate analyses. In addition, overall survival differed significantly between patients with ALBI grades 1 and 2 (hazard ratio, 1.44; 95% confidence interval, 1.09-1.92, P = 0.011) among patients with a Child-Pugh score of 5. Time-dependent receiver operating characteristic analysis showed that ALBI score predicted overall survival better than Child-Pugh score. CONCLUSIONS: Albumin-bilirubin grade is a better predictor of survival in patients with advanced HCC who received sorafenib therapy than Child-Pugh classification.

Using ALBI score at the start of sorafenib treatment to predict regorafenib treatment candidates in patients with hepatocellular carcinoma.

BACKGROUND: Although sorafenib-regorafenib sequential therapy improves the prognosis of patients with hepatocellular carcinoma (HCC), many patients abandon sequential therapy due to worsening hepatic reserve function. Thus, it is important to clarify which patients can be treated using regorafenib. The albumin-bilirubin score is a good biomarker for hepatic reserve function. The aim of this study was to determine whether patient albumin-bilirubin scores at the start of sorafenib treatment could be used to identify candidates for subsequent regorafenib therapy. METHODS: This is a retrospective cohort study. From 2009 to 2017, 267 hepatocellular carcinoma patients treated with sorafenib were enrolled. After sorafenib therapy, 138 progressive disease patients were analyzed. The patients were divided in two groups: (i) regorafenib candidate group (Child-Pugh class A, Eastern Cooperative Oncology Group Performance Status ≤1, and maintained sorafenib tolerance); and (ii) regorafenib non-candidate group. The primary endpoint was the albumin-bilirubin score. We assessed retrospectively whether albumin-bilirubin scores were useful for predicting regorafenib treatment regimen candidacy. RESULTS: For the 138 analyzed patients, the median overall survival duration was 15.6 months in the regorafenib candidate group and 6.8 months in the regorafenib non-candidate group (P < 0.01). Using univariate analysis, etiology, aspartate aminotransferase ≥40 IU/L, prothrombin time ≥85% and albumin-bilirubin score <-2.53 at the start of sorafenib treatment were identified as predictors. Using multivariate analysis, albumin-bilirubin score <-2.53 was the only significant predictor. CONCLUSIONS: Based on the multivariate analysis results, albumin-bilirubin score at the start of sorafenib therapy is a useful marker for identifying candidate patients for starting regorafenib therapy.

Hepatic Function during Repeated TACE Procedures and Prognosis after Introducing Sorafenib in Patients with Unresectable Hepatocellular Carcinoma: Multicenter Analysis.

BACKGROUND/AIM: We evaluated the relationship of hepatic function with repeated transarterial catheter chemoembolization (TACE) and prognosis after sorafenib treatment in various patient cohorts. METHODS: Study 1 comprised of 212 Barcelona clinic liver cancer stage-B (BCLC-B) HCC patients classified as Child-Pugh A (CP-A) and who had received repeated TACE treatments (r-TACE) (naïve:recurrence = 66:146). Study 2 comprised of 435 patients with unresectable HCC classified as CP-A in who sorafenib was introduced (naïve:recurrence = 37:398; CP score 5:6 = 282:153; macro-vessel invasion [MVI]+: extrahepatic metastasis [EHM]+ both negative = 124:226:143). Changes in hepatic function along with CP and albumin-bilirubin (ALBI) score/grade during r-TACE in Study 1, and prognosis after introducing sorafenib in Study 2 were evaluated. RESULTS: Hepatic function worsened to CP-B in 9-14% with each TACE procedure, while 18-21% had a change of classification from ALBI-1 to ALBI-2. When the prognosis of patients with the best CP score of 5 was analyzed, those with ALBI-1 (n = 154) had a better outcome than those with ALBI-2 (n = 128) (MST 17.5 vs. 9.9 months; p = 0.01), while ALBI-1 (n = 43) patients also showed a better outcome than ALBI-2 (n = 34) patients with a CP score of 5 without MVI/EHM (MST: 17.5 vs. 10.0 months; p = 0.029). The Akaike's Information criterion for ALBI-grade (MST: grade 1 vs. 2 = 16.9 vs. 10.4 months; p = 0.001) was also better than that for CP (MST: score 5 vs. 6 = 14.4 vs. 10.5 months; p = 0.003) (3195.6 vs. 3197.5) in all 435 patients. CONCLUSION: The rate of patients with downgraded hepatic function during r-TACE, especially with regard to ALBI-grade, was not low. ALBI-grade was shown to be a better hepatic function assessment tool than CP in patients receiving sorafenib treatment. Strict judgment of TACE-refractory status in patients with unresectable HCC is needed to improve prognosis before downgrading the hepatic function.

Efficacy of branched-chain amino acid supplementation and walking exercise for preventing sarcopenia in patients with liver cirrhosis.

BACKGROUND/AIM: Sarcopenia is recognized as a condition related to quality of life and prognosis in patients with chronic liver disease, although no useful strategy for improving muscle volume and strength has been established. Here, we evaluated the efficacy of supplementation with branched-chain amino acid (BCAA) administration and walking exercise. PATIENTS AND METHODS: From December 2015 to July 2016, 33 Japanese outpatients with liver cirrhosis were enrolled (median: 67 years, HCV : HBV : alcohol : others=26 : 2 : 2 : 3, male : female=13 : 20, Child-Pugh A : B=30 : 3). None had a history of BCAA supplementation. After calculating the average number of daily steps using a pedometer for a 2-3-week period, BCAA supplementation (protein 13.5 g, 210 kcal/day) as a late evening snack and walking exercise (additional 2000 steps/day prescribed) were started. Body composition including muscle volume was analyzed using a bioelectrical impedance analysis method, and serological data and muscle strength (leg, handgrip) were evaluated at enrollment, and then 1, 2, and 3 months after starting the protocol. RESULTS: The median average number of daily steps was 3791 (interquartile range: 2238-5484). The average period of BCAA supplementation was 2.7±0.7 months. During the period from enrollment to 3 months after starting the protocol, HbA1c and NH3 were not significantly changed, whereas the BCAA/tyrosine ratio improved (4.3±1.35 to 5.24±2.04, P=0.001). In addition, the ratios for average daily steps (1.595, P=0.02) as well as muscle volume, leg strength, and handgrip strength (1.013, 1.110, and 1.056, respectively; all P<0.01) were increased at 3 months. CONCLUSION: BCAA supplementation and walking exercise were found to be effective and easily implemented for improving muscle volume and strength in liver cirrhosis patients.

FGF3/FGF4 amplification and multiple lung metastases in responders to sorafenib in hepatocellular carcinoma.

UNLABELLED: The response rate to sorafenib in hepatocellular carcinoma (HCC) is relatively low (0.7%-3%), however, rapid and drastic tumor regression is occasionally observed. The molecular backgrounds and clinico-pathological features of these responders remain largely unclear. We analyzed the clinical and molecular backgrounds of 13 responders to sorafenib with significant tumor shrinkage in a retrospective study. A comparative genomic hybridization analysis using one frozen HCC sample from a responder demonstrated that the 11q13 region, a rare amplicon in HCC including the loci for FGF3 and FGF4, was highly amplified. A real-time polymerase chain reaction-based copy number assay revealed that FGF3/FGF4 amplification was observed in three of the 10 HCC samples from responders in which DNA was evaluable, whereas amplification was not observed in 38 patients with stable or progressive disease (P = 0.006). Fluorescence in situ hybridization analysis confirmed FGF3 amplification. In addition, the clinico-pathological features showed that multiple lung metastases (5/13, P = 0.006) and a poorly differentiated histological type (5/13, P = 0.13) were frequently observed in responders. A growth inhibitory assay showed that only one FGF3/FGF4-amplified and three FGFR2-amplified cancer cell lines exhibited hypersensitivity to sorafenib in vitro. Finally, an in vivo study revealed that treatment with a low dose of sorafenib was partially effective for stably and exogenously expressed FGF4 tumors, while being less effective in tumors expressing EGFP or FGF3. CONCLUSION: FGF3/FGF4 amplification was observed in around 2% of HCCs. Although the sample size was relatively small, FGF3/FGF4 amplification, a poorly differentiated histological type, and multiple lung metastases were frequently observed in responders to sorafenib. Our findings may provide a novel insight into the molecular background of HCC and sorafenib responders, warranting further prospective biomarker studies.

Long-term branched-chain amino acid supplementation improves glucose tolerance in patients with nonalcoholic steatohepatitis-related cirrhosis.

Branched-chain amino acid (BCAA) supplements have mainly been administered as a nutritional intervention for decompensated liver cirrhosis. Several studies have shown that short-term BCAA supplementation improves insulin and glucose tolerance in patients with liver cirrhosis. However, the long-term effects of BCAA supplementation on glucose tolerance and in patients with nonalcoholic steatohepatitis (NASH)-related liver cirrhosis are unknown. Herein, we report 2 cases of NASH-related liver cirrhosis in which long-term BCAA supplementation improved glycemic control. We conclude that in the absence of an effective conventional therapy for NASH-related liver cirrhosis, BCAA supplementation should be considered as an alternative treatment.

Transcatheter arterial chemoembolization with fine-powder cisplatin-lipiodol for HCC.

BACKGROUND/AIMS: Fine-powder cisplatin has recently been developed, allowing the easy manufacture of high-density cisplatin-lipiodol suspensions. The aim of this study is to evaluate the efficacy and toxicity of transcatheter arterial chemoembolization (TACE) with fine-powder cisplatin and lipiodol suspension against advanced hepatocellular carcinoma (HCC). METHODOLOGY: We prospectively analyzed 20 patients (16 men, 4 women) with inoperative advanced HCC without extrahepatic metastases who underwent TACE with fine-powder cisplatin and lipiodol suspension in our hospital between August 2006 and December 2008. All patients were administered a suspension of fine-powder cisplatin at 10 mg/1 cm of tumor diameter. RESULTS: Partial response was seen in 10 cases, with stable disease in 7 cases and progressive disease in 3 cases. Overall response rate was 50%. The 1-year survival rate was 90%. Adverse effects (> or = grade 3) occurred in 40%, with vomiting in 5%, thrombocytopenia in 15%, elevated serum bilirubin in 20%, decreased serum albumin in 5%, fever in 65%, general fatigue in 15% and anorexia in 30%. However, no other life-threatening, adverse events were observed. CONCLUSION: TACE with fine-powder cisplatin suspended in lipiodol provides better therapeutic efficacy, suggesting the potential usefulness of this agent in the treatment of advanced HCC.
