Background: Atezolizumab plus bevacizumab was approved for patients with hepatocellular carcinoma (HCC). Although clinical trials have revealed its efficacy, the outcomes in the real-world clinical practice are unclear. We retrospectively evaluated the efficacy and safety of atezolizumab plus bevacizumab for HCC. Materials and Methods: This is a multicenter study conducted between November 2020 and March 2021. Among the 61 patients, 51 were assessed for progression-free survival (PFS), therapeutic response, and adverse events (AEs). Results: The median PFS was 5.4 months. The objective response rate (ORR) was 35.3%. The disease control rate (DCR) was 86.3%. The incidence rates of AEs at any grade and grade >3 were 98.0% and 29.4%, respectively. The most frequent AE at any grade and grade >3 was hepatic disorder. In patients with a previous history of molecular targeted agent (MTA) or the degree of albumin-bilirubin (ALBI) grade, there were no significant differences in the PFS, ORR, DCR, and incidence rates of AEs. Conclusion: The study demonstrated that atezolizumab plus bevacizumab was effective and safe for patients with HCC even in the real-world setting including patients with a previous MTA history or other than ALBI grade 1.

Weekends-Off Lenvatinib for Unresectable Hepatocellular Carcinoma Improves Therapeutic Response and Tolerability Toward Adverse Events
2020
Background: Although lenvatinib has become the standard therapy for hepatocellular carcinoma (HCC), the high incidence rate of adverse events (AEs) is an issue. This study aimed to clarify the AEs of lenvatinib and the therapeutic impact of five days-on/two days-off administration (i.e., weekends-off strategy) for lenvatinib. Methods: We retrospectively assessed the therapeutic effects and AEs of 135 patients treated with lenvatinib, and the improvement of tolerability and therapeutic efficacy of 30 patients treated with the weekends-off strategy. We also evaluated lenvatinib-induced vascular changes in tumors and healthy organs using a mouse hepatoma model. Results: The incidence rates of any grade and grade ≥ 3 AEs were 82.1% and 49.6%. Fatigue was the most important AE since it resulted in dose reduction and discontinuation. Of the 30 patients who received weekends-off lenvatinib, 66.7% tolerated the AEs. Although 80.8% of the patients showed progression after dose reduction, the therapeutic response improved in 61.5% of the patients by weekends-off lenvatinib. Notably, weekends-off administration significantly prolonged the administration period and survival (p < 0.001 and p < 0.05). The mouse hepatoma model showed that weekends-off administration contributed to recovery of vascularity in the organs. Conclusion: Weekends-off administration of lenvatinib was useful to recover the therapeutic response and tolerability toward AEs.

Deterioration of liver function and aging disturb sequential systemic therapy for unresectable hepatocellular carcinoma
2022
This study aimed to investigate the clinical characteristics of patients with unresectable hepatocellular carcinoma (HCC), who were eligible for sequential systemic therapy. We evaluated 365 patients with HCC who underwent systemic therapy after 2017. The overall survival (OS) was 13.7 months, 19.2 months, and 35.6 months in the first-line, second-line, and third-line or later therapy groups, respectively. Multivariate analysis revealed that the modified-albumin-bilirubin (m-ALBI) grade, macrovascular invasion, extrahepatic spread, discontinuation due to adverse events (AEs), and sequential therapy were independent factors for OS. At the end of each therapy, the ALBI score was significantly worse among patients with discontinuation due to AEs than among those without. The conversion rate to second-line and third-line therapy among patients with discontinuation due to AEs was significantly lower than that among patients without (30.4% vs. 69.2%,
p
< 0.001; 6.7% vs. 58.3%;
p
< 0.001, respectively). In the decision tree analysis, m-ALBI grade 1 or 2a and non-advanced age were selected splitting variables, respectively, for sequential systemic therapy. In conclusion, sequential therapy prolonged the OS of unresectable HCC. Additionally, good hepatic function and non-advanced age were clinically eligible characteristics for sequential systemic therapy.

Survival Benefit of Hepatic Arterial Infusion Chemotherapy over Sorafenib in the Treatment of Locally Progressed Hepatocellular Carcinoma
2021
BACKROUND: Not all patients with hepatocellular carcinoma (HCC) benefit from treatment with molecular targeted agents such as sorafenib. We investigated whether New-FP (fine-powder cisplatin and 5-fluorouracil), a hepatic arterial infusion chemotherapy regimen, is more favorable than sorafenib as an initial treatment for locally progressed HCC. METHODS: To avoid selection bias, we corrected the data from different facilities that did or did not perform New-FP therapy. In total, 1709 consecutive patients with HCC initially treated with New-FP or sorafenib; 1624 (New-FP, n = 644; sorafenib n = 980) were assessed. After propensity score matching (PSM), overall survival (OS) and prognostic factors were assessed (n = 344 each). Additionally, the patients were categorized into four groups: cohort-1 [(without macrovascular invasion (MVI) and extrahepatic spread (EHS)], cohort-2 (with MVI), cohort-3 (with EHS), and cohort-4 (with MVI and EHS) to clarify the efficacy of each treatment. RESULTS: New-FP prolonged OS than sorafenib after PSM (New-FP, 12 months; sorafenib, 7.9 months; p < 0.001). Sorafenib treatment, and severe MVI and EHS were poor prognostic factors. In the subgroup analyses, the OS was significantly longer the New-FP group in cohort-2. CONCLUSIONS: Local treatment using New-FP is a potentially superior initial treatment compared with sorafenib as a multidisciplinary treatment in locally progressed HCC without EHS.

Hepatitis C Virus Elimination Using Direct Acting Antivirals after the Radical Cure of Hepatocellular Carcinoma Suppresses the Recurrence of the Cancer
2022
It remains unclear whether hepatocellular carcinoma (HCC) recurrence in hepatitis C virus (HCV)-infected patients can be suppressed by the elimination of the virus using direct-acting antivirals (DAAs) after radical HCC treatment. We evaluated the sustained inhibitory effect of DAAs on HCC recurrence after curative treatment. This multicenter retrospective study included 190 HCV-positive patients after radical treatment for early-stage HCC. Patients were classified into the DAA treatment group (n = 70) and the non-DAA treatment group (n = 120) after HCC treatment. After propensity score matching (PSM), 112 patients were assessed for first and second recurrences using the Kaplan–Meier method and analyzed using a log-rank test. The first recurrence rates at 1 and 3 years were 3.6% and 42.1% in the DAA treatment group and 21.7% and 61.9% in the non-DAA treatment group, respectively (p = 0.0026). Among 85 patients who received radical treatment, the second recurrence rate at 3 years was 2.2% in the DAA treatment group and 33.9% in the non-DAA treatment group (p = 0.0128). In HCV-positive patients with early-stage HCC, the first and second recurrences were suppressed by DAA therapy after radical treatment, suggesting that the inhibitory effect of DAA therapy on HCC recurrence was sustained.

First‐line sorafenib sequential therapy and liver disease etiology for unresectable hepatocellular carcinoma using inverse probability weighting: A multicenter retrospective study
2021
Background and Aims Sequential therapy with molecular‐targeted agents (MTAs) is considered effective for unresectable hepatocellular carcinoma (HCC) patients. This study purposed to evaluate the efficacy of sequential therapy with sorafenib (SORA) as a first‐line therapy and to investigate the therapeutic impact of SORA in nonalcoholic fatty liver disease (NAFLD) or nonalcoholic steato hepatitis (NASH)‐related HCC. Methods We evaluated 504 HCC patients treated with SORA (Study‐1). The times of administration for sorafenib from 2009 to 2015, 2016 to 2017, and 2018 and later were defined as the early‐, mid‐, and late‐term periods, respectively. Among them, 180 HCC patients treated with SORA in addition to MTAs in the mid‐ and late‐term periods were divided into groups based on disease etiology (NAFLD or NASH [n = 37] and viral or alcohol [n = 143]), and outcomes were compared after inverse probability weighting (IPW) (Study‐2). Results Overall survival (OS) of HCC patients who received sequential MTA therapy after first‐line SORA was significantly longer. The median survival times (MST) were 12.6 versus 17.6 versus 17.4 months in the early‐term group, mid‐term group, and the later‐time group (early vs. mid, p = 0.014, early vs. later. p = 0.045), respectively. (Study‐1). In Study‐2, there was no significant differences in OS between the Virus/alcohol group and the NAFLD/NASH group in patients who received sequential therapy (MST was 23.4 and 27.0 months p = 0.173, respectively). The NAFLD or NASH, female sex, albumin‐bilirubin (ALBI) grade 2b, and major Vp (Vp3/Vp4) were significant factors for OS treated with SORA. Conclusions Sequential therapy with SORA as the first‐line treatment improved the prognosis of unresectable HCC patients and was effective regardless of HCC etiology. Sequential therapy with SORA as the first‐line treatment prolonged the prognosis of unresectable HCC patients and was effective regardless of HCC etiology.

Purpose
Portal vein tumor thrombosis is a critical complication in patients with hepatocellular carcinoma (HCC). This prospective multicenter trial assessed the efficacy of hepatic arterial infusion chemoembolization therapy with cisplatin suspended in lipiodol combined with 5-fluorouracil for HCC patients with portal vein tumor thrombosis.
Methods
We enrolled 52 HCC patients with portal vein tumor thrombosis. They received hepatic arterial infusion chemoembolization therapy with cisplatin suspension in lipiodol and 5-fluorouracil. The primary efficacy endpoint was progression-free survival (PFS), while the secondary endpoints were overall survival (OS), tumor response rate, safety, and tolerability. Independent factors for survival were also evaluated.
Results
The median PFS and OS were 8.6 and 27.0 months, respectively. Ten patients showed complete response, while 29 had partial response (response rate, 75.0 %). The median survival time of 10 patients with complete response and 29 with partial response was 32 months, while that of 15 patients with partial response who later showed disappearance of HCC following additional therapies was 50 months. Multivariate analysis identified response to treatment and disappearance of viable HCC as independent predictors of survival. The treatment was well tolerated, and the only encountered Grade 3 toxicities were thrombocytopenia and hyperbilirubinemia.
Conclusions
Hepatic arterial infusion chemoembolization therapy with cisplatin suspension in lipiodol combined with 5-fluorouracil is effective treatment for unresectable HCC with portal vein tumor thrombosis.

Durable complete response is achieved by balloon‐occluded transcatheter arterial chemoembolization for hepatocellular carcinoma
2022
In 2013 and 2014, the development of microcatheters with balloons for the 4‐Fr system and new embolization materials provided various options for transarterial chemoembolization (TACE), expanding the range of treatment strategies. At our hospital, balloon‐occluded TACE (B‐TACE), conventional TACE (C‐TACE), and drug‐eluting bead TACE (DEB‐TACE) have been actively performed for hepatocellular carcinoma (HCC). This study compared the local recurrence‐free (LRF) periods of nodules with complete necrosis (TE4) obtained using each treatment method by extracting the nodules evaluated as complete response by the modified Response Evaluation Criteria in Solid Tumors. We performed 580 TACE procedures between June 2013 and April 2019. Among them, 58 HCC nodules in 43 patients, 33 nodules in 30 patients, and 45 nodules in 25 patients were evaluated as having complete necrosis after C‐TACE, DEB‐TACE, and B‐TACE, respectively. The time to local recurrence for each nodule was defined as the LRF period, and the quality of TE4 for each TACE was examined. Factors related to overall survival and the LRF period were determined by univariate and multivariate analyses, and overall survival and the LRF period were analyzed using the Kaplan–Meier method. Multivariate analysis of the LRF period showed that B‐TACE was an independent factor. The median LRF periods were 39.3, 13, and 9.1 months for B‐TACE, C‐TACE, and DEB‐TACE, respectively. Moreover, B‐TACE had a significantly longer LRF period than C‐TACE and DEB‐TACE. Conclusion: There was no significant difference between C‐TACE and DEB‐TACE. The LRF period of nodules with TE4 was the longest with B‐TACE, suggesting that B‐TACE should be used to achieve a radical cure in patients with HCC. This study aimed to clarify the clinical question of whether there are differences in the quality of complete necrosis after TACE. The results showed that B‐TACE had a significantly longer LRF period than other TACEs. In addition, the factors associated with a longer LRF period were larger tumor size (> 29 mm) and choice of the B‐TACE procedure.

Primary Treatment with Molecular‐Targeted Agents for Hepatocellular Carcinoma: A Propensity Score‐matching Analysis
2020
Sorafenib and lenvatinib, as molecular‐targeted agents, constitute effective primary treatment options for advanced hepatocellular carcinoma (HCC). However, the choice of optimal primary treatment agent remains controversial. Here, we aimed to assess the respective outcomes between these agents as primary treatment in patients with advanced HCC through use of propensity score–matching analysis (PSMA). We enrolled 670 consecutive patients who were diagnosed with advanced HCC and received sorafenib (n = 524) or lenvatinib (n = 146) as the primary treatment among 18 participating institutions between May 2009 and October 2019. To reduce confounding, we used PSMA regarding seven variables related to advanced HCC prognosis, resulting in the selection of 292 patients (n = 146 for each agent). Following PSMA, no significant difference was observed in the outcome of overall survival time between patients treated with sorafenib or lenvatinib (median survival time 15.3 or 14.9 months, respectively; P = 0.2358). Patients treated with lenvatinib exhibited significantly greater therapeutic effects (response rate: 5% and 31%; disease control rate: 46% and 69% for sorafenib and lenvatinib, respectively; P < 0.0001), but showed significantly lower probability of transition to secondary treatment (sorafenib, 60%; lenvatinib, 45%; P < 0.0269) and higher any adverse events rate (sorafenib, 86%; lenvatinib, 95%; P = 0.0207). Conclusion: As a primary molecular‐targeted agent–based treatment for advanced HCC, our findings suggested that sorafenib is generally appropriate as it offers significantly lower frequency of adverse events and higher probability of transition to secondary treatment, in consideration of the enhanced postprogression survival mediated by sequential treatment. Alternatively, lenvatinib affords a significantly higher therapeutic effect and should be used when immediate tumor reduction is required.

Laparoscopic left hepatectomy for a patient with intrahepatic cholangiocarcinoma metastasis in the falciform ligament: a case report
2021
Background
Intrahepatic cholangiocarcinoma (ICC) is primary cancer of the liver with poor prognosis because of its high potential for recurrence and metastasis. We experienced a rare case of ICC with hematogenous metastasis to the falciform ligament. We aimed to clarify the route of metastasis to the mesentery by increasing the accuracy of preoperative imaging and establish a hepatectomy to control cancer.
Case presentation
An 85-year-old woman was referred to our hospital for a detailed study of progressively increasing liver tumors. She had no subjective symptoms. Her medical history showed hypertension, aneurysm clipping for cerebral hemorrhage, and gallstones. A detailed physical examination and laboratory data evaluation included tumor markers but did not demonstrate any abnormalities. On computed tomography scan, contrast-enhanced ultrasound, and magnetic resonance imaging with gadolinium ethoxybenzyl diethylenetriamine penta-acetic acid, the tumor appeared to be located in liver segment IV, protruding outside the liver. It appeared to contain two distinct components; we suspected ICC in the intrahepatic tumor component. Laparoscopic observation revealed that the extrahepatic lesion was an intra-falciform ligament mass; laparoscopic left hepatectomy was performed. Microscopically, the main tumor in segment IV was 15 mm in diameter and was diagnosed as moderately and poorly differentiated ICC. The tumor of the intra-falciform ligament was not continuous with the main intrahepatic nodule and was also diagnosed as ICC with extensive necrosis. There were no infiltrates in the round ligament of the liver, and several tumor thrombi were found in the small veins of the falciform ligament.
Conclusions
To date, there have been a few reports of metastases of primary liver cancer to the falciform ligament. At the time of preoperative imaging and pathological diagnosis, this case was suggestive of considering that the malignant liver tumor might be suspected of metastasizing to the falciform ligament. Our case improves awareness of this pathology, which can be useful in the future when encountered by hepatic specialists and surgeons.
