Transarterial chemoembolization (TACE) is the standard of care for intermediate stage hepatocellular carcinoma (HCC). We aimed to identify unsuitable cases who were at risk of ALBI-grade migration by TACE. Consecutive 531 BCLC-B HCC patients undergoing TACE were reviewed, and factors associated with ALBI-grade migration were analyzed. There were 129 (24.3%) patients experienced acute ALBI-grade migration after TACE, and 85 (65.9%) out of the 129 patients had chronic ALBI-grade migration. Incidences of acute ALBI-grade migration were 13.9%, 29.0% for patients within or beyond up-to-7 criteria (p &lt, 0.001) and 20.0%, 36.2% for patients within or beyond up-to-11 criteria (p &lt, 0.001), respectively. HBV infection, tumor size plus tumor number criteria were risk factors associated with acute ALBI-grade migration. Bilobar tumor involvement was the risk factor of chronic ALBI-grade migration in patients with acute ALBI-grade migration. Up-to-eleven (p = 0.007) performed better than up-to-seven (p = 0.146) to differentiate risk of dynamic ALBI score changes. Moreover, ALBI-grade migration to grade 3 has adverse effect on survival. In conclusion, tumor burden beyond up-to-eleven was associated with ALBI-grade migration after TACE, indicating that up-to-eleven can select TACE-unsuitable HCC patients who are at risk of liver function deterioration.

Background and Aims: For patients with intermediate-stage hepatocellular carcinoma (HCC), the definition of high tumor burden remains controversial. This study aimed to compare the prognostic value of different criteria of tumor burden in patients with intermediate-stage HCC undergoing transarterial chemoembolization (TACE). Methods: From 2007 to 2019, 632 treatment-naive patients with intermediate-stage HCC undergoing TACE were retrospectively enrolled. We compared different criteria of tumor burden in discriminating radiologic response and survival, including up-to-7, up-to-11, 5–7, 7 lesions criteria, and newly proposed 7–11 criteria. Results: The proportions of patients classified as high tumor burden were varied by different criteria. Among the 5 criteria, 7–11 criteria have the best performance to discriminate complete response (CR) and overall survival (OS) after TACE. In patients with low, intermediate, and high tumor burden classified by 7–11 criteria, the CR rate was 21, 12, and 2.5%, respectively (p < 0.001), and the median OS was 33.1, 22.3, and 11.9 months, respectively (p < 0.001). By multivariate analysis, 7–11 criteria were significantly associated with CR (intermediate vs. high burden, odds ratio = 4.617, p = 0.002; low vs. high burden, odds ratio = 8.675, p < 0.001) and OS (intermediate vs. high burden, hazard ratio = 0.650, p < 0.001; low vs. high burden, hazard ratio = 0.520, p < 0.001). Seven to 11 criteria also had the lowest corrected Akaike information criteria, highest homogeneity value, and highest area under the receiver operating characteristic curve in predicting 1-, 2-, and 3-year mortality among all criteria. Conclusion: Conventional definitions of tumor burden were not optimal for patients with intermediate HCC. The new 7–11 criteria had the best discriminative power in predicting radiologic response and survival in patients with intermediate-stage HCC undergoing TACE.

Background/purpose The treatment of chronic hepatitis C (CHC) has evolved from interferon (IFN)-based therapy to direct acting antivirals (DAAs). The effect of antiviral treatment on outcome of hepatocellular carcinoma (HCC) patients with CHC has not been well analyzed in Taiwan. Methods From April 2015 to May 2018, 199 HCC patients with CHC undergoing DAAs treatment, including 127 having prospectively longitudinal observation, were enrolled. Among them, 107 BCLC 0/A patients achieving curative treatment of HCC were further compared with a historical cohort of 42 HCC patients experienced pegylated interferon (Peg-IFN) plus ribavirin for CHC after curative treatment. Results The sustained virological response (SVR) rates were 95.0% in BCLC stage 0/A (114/120), 97.1% in BCLC B (68/70), and 77.8% in BCLC C (7/9). The median recurrence-free survivals (RFS) between the DAA and IFN arms were of no difference by counting either from antiviral treatment (29.3 mo vs 39.2 mo, p = 0.764) or from curative treatment (65.8 mo vs 44.0 mo, p = 0.130), respectively. Achievement of SVR was the key independent factor associated with RFS and overall survival. The pattern of recurrence was also similar between the DAA and IFN arms. For intermediate stage HCC patients, the median time to tumor progression was 9.2 months from the initiation of DAA therapy, and 90% of patients maintained in BCLC B till 12 months after the DAA treatment. Conclusions The SVR is high within BCLC B HCV-HCC patients by DAAs treatment. The risk of HCC recurrence and progression is not increased by DAAs.

Background/Purpose: Combined hepatocellular-cholangiocarcinoma (cHCC-CCA) is a rare primary liver cancer. Preoperative diagnosis of cHCC-CCA is difficult, and outcome of cHCC-CCA is obscured. Our study aimed to investigate the clinicopathological and radiological features of cHCC-CCA and compare their outcomes with hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC). Methods: From August 2010 to December 2017, 891 patients undergoing liver tumor resection in Taipei Veterans General Hospital, including 30 patients with pathology-proven cHCC-CCA, 819 HCC, and 42 ICC were retrospectively reviewed. Radiological features of contrast-enhanced computed tomography (CT) or magnetic resonance imaging (MRI) in patients with cHCC-CCA were reevaluated by a radiologist. Factors association with disease-free survival (DFS) and overall survival (OS) were analyzed. Results: The mean age of cHCC-CCA, HCC and ICC was similar. Hepatitis B virus infection was prevalent in patients with cHCC-CCA (22/30, 73.3%). Most (70%) of the cHCC-CCA had atypical radiological pattern of HCC and belonged to classic type in pathological features. cHCC-CCA and ICC had worse DFS, but the 5-year OS of cHCC-CCA was substantial adequate after surgery. Of the 891 patients, male gender, advanced T stage, multiple tumor number, alpha-fetoprotein (AFP) level >20 ng/ml, cHCC-CCA, and ICC were factors associated with poor DFS in multivariable analysis. Older age, T stage 3 or 4, presence of macrovascular invasion, AFP >20 ng/mL, cHCC-CCA, and ICC were factors significantly associated with OS. Conclusion: cHCC-CCA is associated with high risk of recurrence following surgical resection as compared with HCC. Closely post-operative monitoring is highly recommended.
