Despite the promising efficacy of atezolizumab plus bevacizumab (atezo/bev), some patients with unresectable hepatocellular carcinoma (HCC) experience disease progression. This retrospective study, which included 154 patients, aimed to evaluate predictors of treatment efficacy of atezo/bev for unresectable HCC. Factors associated with treatment response were examined, focusing on tumor markers. In the high-alpha-fetoprotein (AFP) group (baseline AFP ≥ 20 ng/mL), a decrease in AFP level > 30% was an independent predictor of objective response (odds ratio, 5.517; p = 0.0032). In the low-AFP group (baseline AFP < 20 ng/mL), baseline des-gamma-carboxy prothrombin (DCP) level < 40 mAU/mL was an independent predictor of objective response (odds ratio, 3.978; p = 0.0206). The independent predictors of early progressive disease were an increase in AFP level ≥ 30% at 3 weeks (odds ratio, 4.077; p = 0.0264) and the presence of extrahepatic spread (odds ratio, 3.682; p = 0.0337) in the high-AFP group and up-to-seven criteria, OUT (odds ratio, 15.756; p = 0.0257) in the low-AFP group. In atezo/bev therapy, focusing on early AFP changes, baseline DCP, and tumor burden of up-to-seven criteria are useful in predicting response to treatment.

Recent success of systemic therapeutic agents, including combination immunotherapy, could promote a change in the treatment strategy in patients with advanced hepatocellular carcinoma (HCC). Although hepatic arterial infusion chemotherapy (HAIC) is a treatment option for advanced HCC in Japan, it is not recommended by other guidelines. We discuss the clinical benefits of HAIC compared to sorafenib. The clinical benefits of HAIC are as follows: (1) even a patient with Child–Pugh B HCC (7 or 8 points) is a candidate for HAIC (2) Child–Pugh scores barely decline with the use of HAIC compared with sorafenib (3) HAIC is highly effective in patients with vascular invasion compared with sorafenib; and (4) survival in patients receiving HAIC may not be associated with skeletal muscle volume. In contrast, the disadvantages are problems related with the reservoir system. HAIC has clinical benefits in a subpopulation of patients without extrahepatic metastasis with Child–Pugh A HCC and vascular invasion (especially primary branch invasion or main portal vein invasion) or with Child–Pugh B HCC.

There are limited reports regarding early predictors of objective response (OR) in patients with hepatocellular carcinoma (HCC) treated with lenvatinib. This retrospective study including 70 patients aimed to investigate the efficacy of hepatic biochemical markers. Changes in tumor marker (alpha-fetoprotein (AFP)/des-gamma-carboxy prothrombin (DCP)) levels and albumin&ndash, bilirubin (ALBI) score between the baseline value and that estimated one month after treatment were evaluated. We identified several predictors of OR, including changes in tumor marker levels. The OR rate calculated using modified Response Evaluation Criteria in Solid Tumor (mRECIST) was 41.4%. Response was defined as a reduction in AFP and DCP levels of &ge, 40% from baseline. OR was significantly associated with AFP response, but not with DCP. Predictors of OR were evaluated in two groups (high-AFP group: baseline AFP &ge, 10 ng/mL, low-AFP group: remaining patients). A multivariate analysis identified AFP response (odds ratio, 51.389, p = 0.001) and ALBI score (odds ratio, 6.866, p = 0.039) as independent predictors of OR in the high-AFP and low-AFP groups, respectively. Changes in the ALBI score indicated deterioration in both responders and non-responders, with a significant difference in non-responders (p = 0.003). AFP response, baseline ALBI score, and change in the ALBI score were early predictors of OR in patients with HCC undergoing lenvatinib treatment.

Sorafenib is used worldwide as a first-line standard systemic agent for advanced hepatocellular carcinoma (HCC) on the basis of the results of two large-scale Phase III trials. Conversely, hepatic arterial infusion chemotherapy (HAIC) is one of the most recommended treatments in Japan. Although there have been no randomized controlled trials comparing sorafenib with HAIC, several retrospective analyses have shown no significant differences in survival between the two therapies. Outcomes are favorable for HCC patients exhibiting macroscopic vascular invasion when treated with HAIC rather than sorafenib, whereas in HCC patients exhibiting extrahepatic spread or resistance to transcatheter arterial chemoembolization, good outcomes are achieved by treatment with sorafenib rather than HAIC. Additionally, sorafenib is generally used to treat patients with Child-Pugh A, while HAIC is indicated for those with either Child-Pugh A or B. Based on these findings, we reviewed treatment strategies for advanced HCC. We propose that sorafenib might be used as a first-line treatment for advanced HCC patients without macroscopic vascular invasion or Child-Pugh A, while HAIC is recommended for those with macroscopic vascular invasion or Child-Pugh A or B. Additional research is required to determine the best second-line treatment for HAIC non-responders with Child-Pugh B through future clinical trials.

Transcatheter arterial chemoembolization (TACE) is used as a palliative treatment for unresectable hepatocellular carcinoma (HCC) worldwide. Recently, a novel drug delivery-embolic agent, the drug-eluting bead (DEB), was introduced for TACE. There are a few reports of tumor hemorrhage after TACE using DEB (DEB-TACE) for HCC. However, there have not been any reports of hemobilia immediately after DEB-TACE for HCC with intrahepatic bile duct invasion. Here, the first such case is reported. A 71-year-old woman was admitted to our hospital to undergo DEB-TACE for multiple HCCs with worsening left intrahepatic bile duct dilatation. She was diagnosed with HCC that extensively invaded the left hepatic duct. After DEB-TACE through the left hepatic artery, a hepatic arteriogram showed extra flow of the contrast agent to the left hepatic and common bile ducts. Therefore, transcatheter arterial embolization (TAE) of the responsible vessel was carried out using coils, and no extra flow of the contrast agent was identified. The patient was discharged 14 days after TAE without deterioration of liver function. Although hemobilia immediately after DEB-TACE is rare, there may be increased potential for hemobilia when DEB-TACE is carried out for HCC with extensive bile duct invasion. We suggest that DEB-TACE may be contraindicated for such cases.

Background: Sorafenib is a standard therapy for patients with advanced hepatocellular carcinoma (HCC). However, no predictive biomarkers of sorafenib efficacy have been discovered. Herein, we investigated the impact of body composition, such as skeletal muscle and visceral fat, on the prognosis of advanced HCC patients treated with sorafenib. Methods: We enrolled 100 patients with advanced HCC treated with sorafenib. Prior to receiving sorafenib therapy, skeletal muscle index (SMI) and visceral fat area (VFA) were measured using computed tomography at the third lumbar vertebra and umbilical level, respectively. Muscle depletion was defined as an SMI value < 42 cm2/m2 in men and < 38 cm2/m2 in women. High VFA (H-VFA) was defined as a value ≥100 cm2. In addition to SMI and VFA, we also analyzed various clinical parameters as potential prognostic factors. Results: Multivariate analysis showed that having a tumor number < 7 (hazard ratio [HR] = 0.409, p < 0.001), absence of extrahepatic spread (EHS) (HR = 0.562, p < 0.001), absence of muscle depletion (HR = 0.498, p = 0.006), and H-VFA (HR = 0.556, p = 0.031) were significant factors for long-term survival. Therefore, we evaluated the prognosis of those with no muscle depletion with H-VFA. The no muscle depletion with H-VFA group showed significantly longer survival than the other group (median survival time 15.6 vs. 11.0 months, p = 0.003). Multivariate analysis showed that having a tumor number < 7 (HR = 0.454, p = 0.001), absence of EHS (HR = 0.511, p = 0.008), and no muscle depletion with H-VFA (HR = 0.454, p = 0.002) were significant predictors of survival. Conclusions: We identified no muscle depletion with H-VFA as a novel biomarker for advanced HCC patients treated with sorafenib.

Aim Sorafenib is the recommended standard of care for advanced hepatocellular carcinoma (HCC) patients. However, hepatic arterial infusion chemotherapy (HAIC) is a treatment option in Asia. We recently developed the ‘assessment for continuous treatment with HAIC’ (ACTH) score to guide decision-making for continuous HAIC treatment. The purpose of this study was to validate the utility of the ACTH score in a dedicated cohort. Methods One-hundred and thirty-one advanced HCC patients were enrolled in this study (90 in the training group and 41 in the validation group). The point score (range: 0–3) was calculated as follows: Child-Pugh score before HAIC (A = 0, B = 1), alpha-fetoprotein (AFP) response (yes = 0, no = 1), and des-gamma-carboxy prothrombin (DCP) response (yes = 0, no = 1). AFP and DCP responses were assessed 2 weeks after HAIC induction; a positive response was defined as a reduction of ≥20% from the baseline. Results The DCP response in the validation group was significantly associated with treatment response, and the median survival time (MST) was longer in patients with an ACTH score ≤1 (15.9 months) than in those with a score ≥2 (7.0 months; p = 0.002). Survival in all patients showed significant stratification according to the ACTH score; the MSTs associated with scores of 0, 1, 2, and 3 points were 21.7, 14.4, 9.5, and 3.8 months, respectively. Conclusions The ACTH score can aid in the therapeutic assessment and continued treatment planning of HCC patients receiving HAIC.

AimSorafenib is used as a first-line treatment for advanced hepatocellular carcinoma (HCC). However, hepatic arterial infusion chemotherapy (HAIC) has also gained acceptance, but only in Japan. We explored the role of body composition as a factor affecting the survival benefit of HAIC compared to sorafenib for the treatment of advanced HCC.MethodsWe conducted a retrospective study using the clinical records of 133 patients with advanced HCC treated either with HAIC or sorafenib. Prior to treatment induction, skeletal muscle index and visceral fat area (VFA) were measured at the third lumbar vertebral and umbilical levels, respectively, using computed tomography. Muscle depletion and high-VFA (H-VFA) were defined using published cut-offs. We analyzed clinical parameters, including body composition as prognostic factors.ResultsIn the HAIC group, multivariate analysis identified a positive response to HAIC (hazard ratio [HR], 0.438; p = 0.022), and conversion from HAIC to sorafenib (HR, 0.374; p = 0.008) as favorable prognostic factors for survival. In contrast, tumor number < 7 (HR, 0.475; p = 0.008), absence of extra-hepatic spread (HR, 0.511; p = 0.015), absence of muscle depletion (HR, 0.555; p = 0.044), and H-VFA (HR, 0.483; p = 0.015) were studied in the sorafenib group.ConclusionsBody composition was identified as a prognostic factor for patient survival after treatment with sorafenib, but not for HAIC, and may be used as a biomarker when selecting between HAIC or sorafenib treatment of patients with advanced HCC. Additionally, conversion to sorafenib in patients receiving HAIC could improve survival regardless of response status.
