The efficacy of hepatic arterial infusion chemotherapy for the treatment of advanced hepatocellular carcinoma (HCC) remains unclear. The outcome of 476 patients with HCC who underwent hepatic arterial infusion chemotherapy with 5-fluorouracil and cisplatin (HAIC) were compared with 1466 patients who did not receive active therapy. A survival benefit of the therapy after adjusting for known risk factors was observed (hazard ratio, 0.48; 95% CI, 0.41–0.56; P<0.0001). In propensity score-matched analysis (n=682), median survival time was longer for patients who underwent chemotherapy (14.0 months) than for patients who did not receive active treatment (5.2 months, P<0.0001). For advanced HCC, HAIC is considered to be an effective treatment.

Background: Twist, a transcription factor of the basic helix-loop-helix class, is reported to regulate cancer metastasis. It is known to induce epithelial-mesenchymal transition (EMT). In this study, we evaluated the expression of twist and its effect on cell migration in hepatocellular carcinoma (HCC). Methods: We examined twist expression using immunohistochemistry in 20 tissue samples of hepatocellular carcinoma, and assessed twist expression in HCC cell lines by RT-PCR and Western blot analysis. Ectopic twist expression was created by introducing a twist construct in the twist-negative HCC cell lines. Endogenous twist expression was blocked by twist siRNA in the twist-positive HCC cell lines. We studied EMT related markers, E-cadherin, Vimentin, and N-cadherin by Western blot analysis. Cell proliferation was measured by MTT assay, and cell migration was measured by in vitro wound healing assay. We used immunofluorescent vinculin staining to visualize focal adhesion. Results: We detected strong and intermediate twist expression in 7 of 20 tumor samples, and no significant twist expression was found in the tumor-free resection margins. In addition, we detected twist expression in HLE, HLF, and SK-Hep1 cells, but not in PLC/RPF/5, HepG2, and Huh7 cells. Ectopic twist-expressing cells demonstrated enhanced cell motility, but twist expression did not affect cell proliferation. Twist expression induced epithelial-mesenchymal transition together with related morphologic changes. Focal adhesion contact was reduced significantly in ectopic twist-expressing cells. Twist-siRNA-treated HLE, HLF, and SK-Hep1 cells demonstrated a reduction in cell migration by 50, 40 and 18%, respectively. Conclusion: Twist induces migratory effect on hepatocellular carcinoma by causing epithelial-mesenchymal transition.

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.

Introduction: The ALBI score is acknowledged as the gold standard for the assessment of liver function in patients with hepatocellular carcinoma (HCC). Unlike the Child-Pugh score, the ALBI score uses only objective parameters, albumin (Alb) and total bilirubin (T.Bil), enabling a better evaluation. However, the complex calculation of the ALBI score limits its applicability. Therefore, we developed a simplified ALBI score, based on data from a large-scale HCC database.We used the data of 5,249 naïve HCC cases registered in eight collaborating hospitals. Methods: We developed a new score, the EZ (Easy)-ALBI score, based on regression coefficients of Alb and T.Bil for survival risk in a multivariate Cox proportional hazard model. We also developed the EZ-ALBI grade and EZ-ALBI-T grade as alternative options for the ALBI grade and ALBI-T grade and evaluated their stratifying ability. Results: The equation used to calculate the EZ-ALBI score was simple {[T.Bil (mg/dL)] – [9 × Alb (g/dL)]}; this value highly correlated with the ALBI score (correlation coefficient, 0.981; p < 0.0001). The correlation was preserved across different Barcelona clinic liver cancer grade scores (regression coefficient, 0.93–0.98) and across different hospitals (regression coefficient, 0.98–0.99), indicating good generalizability. Although a good agreement was observed between ALBI and EZ-ALBI, discrepancies were observed in patients with poor liver function (T.Bil, ≥3 mg/dL; regression coefficient, 0.877). The stratifying ability of EZ-ALBI grade and EZ-ALBI-T grade were good and their Akaike’s information criterion values (35,897 and 34,812, respectively) were comparable with those of ALBI grade and ALBI-T grade (35,914 and 34,816, respectively). Conclusions: The EZ-ALBI score, EZ-ALBI grade, and EZ-ALBI-T grade are useful, simple scores, which might replace the conventional ALBI score in the future.
