RESUMEN
INTRODUCTION: In 2021, the LEOPARD trial reported that the combination of lenvatinib+one-shot cisplatin infusion might contribute to improving the results of conventional advanced hepatocellular carcinoma (HCC) treatment. Thus, combination therapy with lenvatinib and catheterization has emerged as a focal point in treating advanced HCC. Conversely, the New FP regimen consists of low-dose cisplatin (CDDP) combined with 5-fluorouracil (5-FU) and lipiodol via hepatic arterial infusion chemotherapy (HAIC), with a high response rate of approximately 70%. Therefore, lenvatinib+New FP (LEN-New FP) may be a more promising treatment for HCC. Here, we report six patients who were administered LEN+New FP and achieved high therapeutic efficacy. Among them, one case had an interesting clinical course, which has been described in detail. MATERIALS AND METHODS: This study included six patients who were administered 12 mg or 8 mg of lenvatinib once daily based on a body weight of ≥60 kg or <60 kg, respectively, along with 50 mg of cisplatin in 5-10 mL lipiodol, and a continuous infusion of 5-FU (1500 mg/5 days) infused every 2-4 weeks. Tumor evaluations were performed 4-8 weeks after the initiation of New FP administration and every 8-12 weeks thereafter. RESULTS: The median patient age was 65 years. All patients had a history of prior treatment with atezolizumab and bevacizumab and one of the factors associated with poor overall survival for New FP monotherapy, such as a maximum tumor diameter ≥7 cm and bilobular multifocal distribution. Four (67%) patients had severe vascular invasion. The best objective response and disease control rates were 83% and 100%, respectively. The best response of the target lesion was complete remission in four out of six patients. CONCLUSION: The LEN-New FP combination for advanced HCC showed a high response rate and was more effective in high-risk patients with factors associated with poor overall survival than that reported with conventional New FP monotherapy. Additionally, LEN-New FP exhibited extremely high objective response and disease control rates and was well tolerated, including in cases where it was considered second- or third-line systemic chemotherapy for advanced HCC. Thus, LEN-New FP can serve as a breakthrough therapy for advanced HCC based on appropriate case selection.
RESUMEN
PURPOSE: This study aimed to investigate the safety and efficacy of lenvatinib in real-world settings, including patients excluded from the REFLECT trial, a phase III trial that compared lenvatinib with sorafenib. PATIENTS AND METHODS: This multicenter, nonrandomized, open-label prospective study was conducted at 10 medical facilities in Japan (jRCTs031190017). Eligible patients had advanced hepatocellular carcinoma (HCC) and were suitable for lenvatinib therapy. The study included patients with high tumor burden (with >50% intrahepatic tumor volume, main portal vein invasion, or bile duct invasion), Child-Pugh B status, and receiving lenvatinib as second-line therapy following atezolizumab plus bevacizumab. RESULTS: From December 2019 to September 2021, 59 patients were analyzed (47 and 12 patients with Child-Pugh A and B, respectively). In patients with Child-Pugh A, the frequency of aspartate aminotransferase elevation was high (72.7%) in the high-burden group. No other significant ad verse events (AE) were observed even in second-line treatment. However, patients with Child-Pugh B had high incidence of grade ≥3 AE (100.0%) and high discontinuation rates caused by AE (33.3%) compared with patients with Child-Pugh A (80.9% and 17.0%, respectively). Median progression-free survival was 6.4 and 2.5 months and median overall survival was 19.7 and 4.1 months in Child-Pugh A and B, respectively. Lenvatinib plasma concentration was higher in patients with Child-Pugh B on days 8 and 15 and correlated with dose modifications and lower relative dose intensity. CONCLUSIONS: Lenvatinib is safe and effective for advanced HCC in patients with Child-Pugh A, even with high tumor burden. However, it carries a higher risk of AE and may not provide adequate efficacy for patients with Child-Pugh B status.

PURPOSE: This study aimed to predict the ability to insert a 4-5 French (Fr) catheter insertion with a guidewire into the common hepatic artery (CHA) based on celiac trunk morphology. METHODS: This retrospective study included 64 patients who underwent balloon-occluded transcatheter arterial chemoembolization (n = 56), transcatheter arterial chemotherapy (n = 2), or were fitted with an implantable port system (n = 6) between June 2019 and December 2019 in our institution. The morphology of the celiac trunk was classified into three types (upward, horizontal, and downward) based on celiac angiography. The aortic-celiac trunk angle was measured on sagittal images of preprocedural contrast-enhanced computed tomography (CT). We reviewed whether a 4-5-Fr shepherd's hook catheter could advance beyond the CHA using a 0.035-inch guidewire (Radifocus® Guidewire M; Terumo). Three patients were diagnosed with median arcuate ligament syndrome (MALS) based on the characteristic hook shape of the celiac artery on sagittal images of contrast-enhanced CT. The predictive ability of celiac angiography and preprocedural CT for CHA insertion success was evaluated. In unsuccessful cases, the balloon anchor technique (BAT) was attempted as follows: (1) a 2.7/2.8-Fr microballoon catheter (Attendant Delta; Terumo) was placed beyond the proper hepatic artery, and (2) the balloon was inflated as an anchor for parent catheter advancement. RESULTS: Upward, horizontal, and downward celiac trunk types were noted in 42, 9, and 13 patients, respectively. The median CT angle was 122.83° (first quartile-third quartile, 102.88°-136.55°). Insertion in the CHA using the guidewire was successful in 56 of 64 patients (87.50%), and the success rate in the downward type was significantly lower than that in the upward type [42/42 (100%) vs. 7/13 (53.85%), P < 0.001]. The CT angle was significantly larger downward in the unsuccessful group than in the successful group (121.03° vs. 140.70°, P = 0.043). Celiac angiography had a significantly higher area under the curve (AUC) than preprocedural CT (AUC = 0.91 vs. AUC = 0.72, P = 0.040). All three cases of MALS showed unsuccessful CHA insertion. In all eight patients with unsuccessful insertion, the catheter could be advanced using the BAT [8/8 (100%)]. CONCLUSION: Celiac angiography and preprocedural CT could predict CHA catheter insertion using a guidewire, and celiac angiography had high predictability. CT could detect MALS, a risk factor for unsuccessful CHA insertion.

OBJECTIVE: This study prospectively observed the incidence of all malignancies and the prognosis of all patients in a population of patients who achieved Sustained Virological Response (SVR) with a 100% capture rate. DESIGN: A prospective study of 651 SVR cases was conducted from July 2013 to December 2021. The primary endpoint was the occurrence of all malignancies, and the secondary endpoint was overall survival. The cancer incidence during the follow-up period was calculated using the man-year method, and risk factors were analyzed. In addition, sex- and age-matched standardized mortality ratio (SMR) was used to compare the general population with the study population. RESULTS: The overall median follow-up was 5.44 years. 107 malignancies occurred in 99 patients during the follow-up. The incidence of all malignancies was 3.94/100 person-years. The cumulative incidence was 3.6% at 1 year, 11.1% at 3 years, and 17.9% at 5 years, and continued to increase almost linearly. The incidence of liver cancer and non-liver cancer was 1.94/100 patient-years vs. 1.81%/100 patient-years. The 1-year, 3-year, and 5-year survival rates were 99.3%, 96.5%, and 94.4%, respectively. This life expectancy was compared to the standardized mortality ratio of the Japanese population, which proved non-inferior. CONCLUSION: It was found that malignancies of other organs occur as frequently as hepatocellular carcinoma (HCC). Therefore, follow-up of patients who have achieved SVR should focus not only on HCC but also on malignant tumors of other organs, and lifelong follow could contribute prolonged life expectancy for the previously short-lived.

To gain a better understanding of the effects of biologics, we evaluated clinical outcomes in patients with moderate to severe exacerbations of ulcerative colitis (UC). This retrospective, multicenter study retrieved the entire clinical courses of UC patients who began treatments between 2004 and 2018. All exacerbations and clinical parameters, including treatment details for exacerbations and both remission and re-exacerbation dates, were identified during the observation period. Two different endpoints, the cumulative incidence rates of surgical resection and re-exacerbation, were evaluated separately in moderate to severe exacerbation events. Among 1401 patients, 1626 exacerbation events were determined according to a partial Mayo score (remission: < 2, mild: 2-4, moderate: 5-7, and severe: > 7). During the observation period, as administration rates of biologics increased, both surgical resection and hospitalization rates decreased, for 959 moderate to severe exacerbation events. We confirmed that biologics significantly reduced the cumulative re-exacerbation rate in moderate to severe exacerbation events during the study period compared with suboptimal therapies (a 0.507-fold decreased risk according to COX regression analysis, P < 0.001). However, they had not enough impact in reducing the cumulative incidence rate of surgical resection in moderate to severe exacerbation events that were corticosteroid-refractory or dependent (a 0.878-fold decreased risk according to COX regression analysis, P = 0.606). Biologics may improve remission duration, but these agents had no significant impact in reducing the risk of surgical resection in moderate to severe active UC.

The screening of gastroesophageal varices (GEV) is critical in hepatocellular carcinoma (HCC) management. Contrast-enhanced computed tomography (CECT) is often performed in patients with HCC. Therefore, this study aimed to examine the use of CECT in screening for GEV and predicting GEV bleeding. This retrospective study enrolled 312 consecutive patients who are initially diagnosed with HCC, measured the lower esophageal (EIV) and fundal intramural vessel (FIV) diameter on CECT, examined the changes after 1, 2, and 3 years, and verified the relationship with GEV bleeding. The EIV and FIV diameter on CECT correlates well with endoscopic variceal classification. EIV significantly worsened after 2 and 3 years. FIV showed worsening at both 1, 2, and 3 years. Cumulative GEV bleeding rates were 3.7% at 1 year and 6.2% at 3 years. The multivariate analysis revealed that EIV, FIV, and portal vein tumor thrombus were associated with GEV bleeding. Furthermore, EIV deterioration at 1, 2, and 3 years correlated with GEV bleeding. In conclusion, CECT is useful in variceal management during the longitudinal clinical course of HCC, and has the potential to decrease screening endoscopy. With deterioration in EIV, treatments should be considered due to a high-risk GEV bleeding.

BACKGROUND: With the evolution of personalized medicine in the field of oncology, which includes optimal treatment selection using next-generation sequencing-based companion diagnostic systems and tumor-agnostic treatments according to common biomarkers, a liver tumor biopsy technique that can obtain a sufficient specimen volume must be established. The current study aimed to evaluate the safety and availability of a liver tumor biopsy technique with multiple puncture sites made using a coaxial introducer needle and embolization with gelatin sponge particles. METHODS: Patients with primary or metastatic liver cancer who underwent liver tumor biopsies with puncture tract embolization using gelatin sponge (Spongel®) from October 2019 to September 2020 were included in the study. The complication and diagnostic rates were evaluated, and whether the specimen volume was sufficient for Foundation® CDx was investigated. RESULTS: In total, 96 patients were enrolled in this analysis. The median total number of puncture times per patient was 3 (range 1-8). The pathological diagnostic rate was 79.2%. Using the FoundationOne® CDx, specimens with a sufficient volume required for genomic medicine were collected in 84.9% of patients. The incidence rate of bleeding was 4.2% (n = 4), and only one patient presented with major bleeding requiring transfusion. CONCLUSIONS: Liver biopsy with puncture tract embolization using a gelatin sponge may be safe and effective for collecting specimens with a volume sufficient for modern cancer treatments.

BACKGROUND AND AIMS: The prognosis of patients with advanced hepatocellular carcinoma (HCC) is expected to improve as multiple molecular target agents (MTAs) are now available. However, the impact of the availability of sequential MTAs has not been fully verified yet. APPROACH AND RESULTS: We retrospectively collected the data on the whole clinical course of 877 patients who received any MTAs as first-line systemic therapy for advanced HCC between June 2009 and March 2019. The study population was divided into 3 groups according to the date of first-line MTA administration (period 1: 2009-2012, n = 267; period 2: 2013-2016, n = 352; period 3: 2017-2019, n = 258). Then, we compared the number of MTAs used, overall survival (OS), and MTA treatment duration among the 3 groups. Analysis was also performed separately for advanced-stage and nonadvanced-stage HCC. The proportion of patients who received multiple MTAs was remarkably increased over time (1.1%, 10.2%, and 42.6% in periods 1, 2, and 3, respectively, p < 0.001). The median OS times were prolonged to 10.4, 11.3, and 15.2 months in periods 1, 2, and 3, respectively (p = 0.016). Similarly, the MTA treatment durations were extended (2.7, 3.2, and 6.6 months in periods 1, 2, and 3, respectively; p < 0.001). We confirmed that the correlation between OS and MTA treatment duration was strengthened (period 1: 0.395, period 2: 0.505, and period 3: 0.667). All these trends were pronounced in the patients with advanced-stage HCC but limited in the patients with nonadvanced-stage HCC. CONCLUSIONS: The availability of multiple MTAs had steadily improved the prognosis of patients with advanced HCC patients, particularly advanced-stage HCC patients.
RESUMEN
BACKGROUND/AIMS: Organ failure in patients with acute decompensation (AD) is a defining characteristic of acute-on-chronic liver failure (ACLF). However, the clinical features of AD during the long-term clinical course of hepatocellular carcinoma (HCC) are still poorly understood. This study aimed to clarify features and impact of AD/ACLF on the prognosis of patients after treatment for HCC. METHODS: This retrospective study enrolled 556 consecutive patients who were initially diagnosed with HCC, and analyses were conducted taking into account HCC treatment type, HCC stage, and presence or absence of cirrhosis. RESULTS: During follow-up, 299 patients with AD were hospitalized. AD occurrence is closely related to prognosis, regardless of the presence or absence of cirrhosis and HCC stage, and early-onset AD (within 90 days after HCC treatment) has negative impact on prognosis. In the intermediate-advanced-stage group, surgical resection had a positive impact on AD incidence post-treatment. After systemic therapy for HCC, renal impairment was the predictive factors for AD development. The 28/90-day mortality rate was higher among 41 cases (13.7%) with AD who exhibited ACLF as compared with cases without ACLF. AD without cirrhosis had similar ACLF incidence and short-term mortality, compared to AD with cirrhosis. The prognostic model using a decision-tree-based approach, which includes ACLF, bilirubin level, HCC progression, and MELD score is useful for predicting 90- or 28-day mortality after AD diagnosis. CONCLUSIONS: Careful management of patients with HCC who are hospitalized with AD is necessary, considering ACLF, HCC progression, and liver function.

BACKGROUND: There is no standard posttreatment for patients with advanced hepatocellular carcinoma (HCC) in whom lenvatinib therapy has failed. This study aimed to investigate rates of migration to posttreatment after lenvatinib and to explore candidates for second-line agents in the patients with failed lenvatinib therapy. METHODS: We retrospectively collected data on patients with advanced HCC who received lenvatinib as the first-line agent in 7 institutions. RESULTS: Overall survival and progression-free survival (PFS) of 178 patients who received lenvatinib as the first-line agent were 13.3 months (95% confidence interval [CI], 11.5-15.2) and 6.7 months (95% CI, 5.6-7.8), respectively. Sixty-nine of 151 patients (45.7%) who discontinued lenvatinib moved on to posttreatment. The migration rates from lenvatinib to the second-line agent and from the second-line agent to the third-line agent were 41.7 and 44.4%, respectively. Based on multivariate analysis, response to lenvatinib (complete or partial response according to modified RECIST) and discontinuation of lenvatinib due to radiological progression, as well as male were associated with a significantly higher probability of migration to posttreatment after lenvatinib. On the other hand, alpha-fetoprotein levels of 400 ng/mL or higher was correlated with a significantly lower probability of migration to posttreatment after lenvatinib. Of 63 patients who received second-line systemic therapy, 53 (84.2%) were administered sorafenib. PFS, objective response rate (ORR), and disease control rate (DCR) for sorafenib treatment were 1.8 months (95% CI, 0.6-3.0), 1.8%, and 20.8%, respectively. According to the Cox regression hazard model, Child-Pugh class B significantly contributed to shorter PFS. PFS, ORR, and DCR of 22 patients who received regorafenib after lenvatinib in any lines were 3.2 months (range, 1.5-4.9 months), 13.6%, and 36.3%, respectively. Similarly, PFS, ORR, and DCR of 17 patients who received regorafenib after lenvatinib in the third-line (after sorafenib) were 3.8 months (range, 1.1-6.5 months), 17.6%, and 41.2%, respectively. CONCLUSION: Sorafenib may not be a candidate for use as a posttreatment agent after lenvatinib, according to the results of the present study. Regorafenib has the potential to become an appropriate posttreatment agent after lenvatinib.
RESUMEN
BACKGROUND AND AIM: Immune checkpoint inhibitors and their combination with other agents have recently been available in advanced hepatocellular carcinoma (HCC). Hence, a thorough understanding of the tumor microenvironment based on tumor samples is yet to be achieved. This study aimed to explore the tumor microenvironment in advanced HCC in terms of microsatellite instability-high (MSI-H) by using tumor samples from advanced HCC patients eligible for systemic therapy. METHODS: MSI-H was assessed by polymerase chain reaction, and the expression of mismatch repair proteins, PD-L1, CD8, VEGF, and HLA-class1 was evaluated by immunohistochemistry. Whole-exome sequencing was performed for MSI-H tumor samples. RESULTS: Of 50 patients, one (2.0%) was confirmed with MSI-H. In the MSI-H advanced HCC tumor, a high tumor mutation burden, infiltration of CD8+ lymphocytes, and low expression of VEGF were identified. Although PD-L1 expression was negative, there was shrinkage of tumor following pembrolizumab. However, another tumor nonresponsive to pembrolizumab was present simultaneously. Checking the Cancer Genome Atlas (TCGA) database, we found a similar case to this patient. The TCGA case had unique gene features of miR-21 and miR-155 overexpression and hypermethylation of the MSH2 gene. CONCLUSION: We identified a very small number of MSI-H cases in HCC using one tumor biopsy sample for each patient with advanced HCC. In addition, epigenetic aberrations possibly lead to MSI-H in HCC patients. Since different HCC clones might coexist in the liver, sampling from multiple tumors should be considered to clarify the true proportion of MSI-H in HCC and to analyze tumor microenvironments.
RESUMEN
FGF19/FGFR4 autocrine signaling is one of the main targets for multi-kinase inhibitors (MKIs). However, the molecular mechanisms underlying FGF19/FGFR4 signaling in the antitumor effects to MKIs in hepatocellular carcinoma (HCC) remain unclear. In this study, the impact of FGFR4/ERK signaling inhibition on HCC following MKI treatment was analyzed in vitro and in vivo assays. Serum FGF19 in HCC patients treated using MKIs, such as sorafenib (n = 173) and lenvatinib (n = 40), was measured by enzyme-linked immunosorbent assay. Lenvatinib strongly inhibited the phosphorylation of FRS2 and ERK, the downstream signaling molecules of FGFR4, compared with sorafenib and regorafenib. Additional use of a selective FGFR4 inhibitor with sorafenib further suppressed FGFR4/ERK signaling and synergistically inhibited HCC cell growth in culture and xenograft subcutaneous tumors. Although serum FGF19high (n = 68) patients treated using sorafenib exhibited a significantly shorter progression-free survival and overall survival than FGF19low (n = 105) patients, there were no significant differences between FGF19high (n = 21) and FGF19low (n = 19) patients treated using lenvatinib. In conclusion, robust inhibition of FGF19/FGFR4 is of importance for the exertion of antitumor effects of MKIs. Serum FGF19 levels may function as a predictive marker for drug response and survival in HCC patients treated using sorafenib.

BACKGROUND AND AIM: Standardization of the sedation protocol during radiofrequency ablation (RFA) in patients with hepatocellular carcinoma (HCC) is needed. This randomized, single-blind, investigator-initiated trial compared clinical outcomes during and after RFA using propofol and midazolam, respectively, in patients with HCC. METHODS: Few- and small-nodule HCC patients (≤3 nodules and ≤3 cm) were randomly assigned to either propofol or midazolam. Patient satisfaction was assessed using a 100-mm visual analog scale (VAS) (1 mm = not at all satisfied, 100 mm = completely satisfied). Sedation recovery rates 1, 2, 3, and 4 h after RFA were evaluated based on Modified Observer's Assessment of Alertness/Sedation (MOAA/S) scores; full recovery was defined as a MOAA/S score of 5. RESULTS: Between July 2013 and September 2017, 143 patients with HCC were enrolled, and 135 patients were randomly assigned to the treatment group. Compared with midazolam, propofol exhibited similar median procedural satisfaction (propofol: 73.1 mm, midazolam: 76.9 mm, P = 0.574). Recovery rates 1 and 2 h after RFA were higher in the propofol group than in the midazolam group. Meanwhile, recovery rates observed 3 and 4 h after RFA were similar in the two groups. The safety profiles during and after RFA were almost identical in the two groups. CONCLUSION: Patient satisfaction was almost identical in patients receiving propofol and midazolam sedation during RFA. Propofol sedation resulted in reduced recovery time compared with midazolam sedation in patients with HCC. The safety profiles of both propofol and midazolam sedation during and after RFA were acceptable.
RESUMEN
Macrovascular invasion (MVI), including portal vein tumor thrombosis (PVTT), is strongly associated with poor prognosis in patients with hepatocellular carcinoma (HCC). While recommended standard treatment for patients with advanced HCC is systemic therapy, various treatment approaches, including resection, transarterial chemoembolization, and radiation, have been empirically suggested to improve prognosis by eliminating or controlling MVI. Herein, we report our experience of a case with advanced HCC where MVI was controlled by carbon-ion radiotherapy (CIRT) while on systemic therapy, resulting in a prolonged survival. A female patient with HCC in her early 60s had multiple intrahepatic lesions (maximum 60 mm in diameter) with PVTT. The PVTT of this patient had reached the main trunk of the portal vein despite the use of lenvatinib. The other intrahepatic lesions of the patient, except PVTT, had been controlled by lenvatinib. Therefore, hoping to control PVTT, we attempted CIRT. The patient resumed lenvatinib therapy after the irradiation. During lenvatinib re-treatment, no evident progression of PVTT was observed in the patient.
RESUMEN
BACKGROUND: Prior to the approval of sorafenib, hepatic arterial infusion chemotherapy (HAIC) was offered to patients with advanced hepatocellular carcinoma (HCC) in East Asia, particularly Japan. According to the Japanese guidelines, HAIC is recommended as one of the treatment options in patients without extrahepatic metastasis (EHM). METHODS: The present cohort study compared the use of HAIC and sorafenib on outcomes of patients with advanced HCC. Consecutive patients with advanced HCC who received HAIC or sorafenib as a first-line systemic therapy were enrolled from 10 Japanese institutions. The primary outcomes were overall survival (OS) in patients with macrovascular invasion (MVI), but without EHM, and OS in patients without both MVI and EHM. RESULTS: Between 2009 and 2016, 2,006 patients were enrolled (541 HAIC patients, 1,465 sorafenib patients). After propensity score matching, the OS of patients with MVI but without EHM was significantly longer in the HAIC group compared with the sorafenib group (10.1 vs. 9.1 months for the HAIC and sorafenib groups, respectively; n = 170 for each group; hazard ratio [HR] 0.668; 95% confidence interval [95% CI] 0.475-0.935; p = 0.018). There was no significant difference in OS between patients without both MVI and EHM (12.2 vs. 15.4 months for the HAIC and sorafenib groups, respectively; n = 76 in each cohort after propensity score matching; HR 1.227; 95% CI 0.699-2.155; p = 0.475). CONCLUSION: HAIC is a potential front-line treatment choice in a subpopulation of patients with advanced HCC with MVI but without EHM.
RESUMEN
BACKGROUND: Intermediate-stage hepatocellular carcinoma (HCC) has a high frequency of recurrence and progression to advanced stage after transarterial chemoembolization (TACE), particularly in patients with high tumor burden. Promising new results from immune checkpoint inhibitors (ICIs) and ICI-based therapies are expected to replace TACE, especially in HCC patients with high tumor burden. AIMS: The present study aimed to evaluate the effectiveness of TACE with a view to design clinical trials comparing TACE and ICIs. METHODS: We retrospectively identified intermediate-stage HCC patients undergoing TACE from our database and subdivided patients into low- and high-burden groups based on three subclassification models using the diameter of the maximum tumor and the number of tumors. Clinical outcomes were compared between low- and high-burden intermediate-stage HCC. RESULTS: Of 1,161 newly diagnosed HCC patients, 316 were diagnosed with intermediate-stage disease and underwent TACE. The median overall survival from high-burden intermediate-stage disease was not significantly different by clinical course, reaching high tumor burden in all subclassification models. The prognosis of high-burden patients after initial TACE was poor compared with low-burden patients for two models (except for the up-to-seven criteria). In all three models, high-burden patients showed a poor durable response rate (DRR) both ≥3 months and ≥6 months and poor prognosis after TACE. Moreover, patients with confirmed durable response ≥3 months and ≥6 months showed better survival outcomes for high-burden intermediate-stage HCC. CONCLUSIONS: Our results demonstrate the basis for selecting a population that would not benefit from TACE and setting DRR ≥3 months or ≥6 months as alternative endpoints when designing clinical trials comparing TACE and ICIs.
RESUMEN
BACKGROUND: The present study aimed to assess the efficacy and safety of lenvatinib and verify the possibility of lenvatinib for the expanded indication from the REFLECT trial in patients with advanced hepatocellular carcinoma (HCC) in real-world practice, primarily focusing on the population that was excluded in the REFLECT trial. METHODS: We retrospectively collected data on patients with advanced HCC who were administered lenvatinib in 7 institutions in Japan. RESULTS: Of 152 advanced HCC patients, 95 and 57 patients received lenvatinib in first-line and second- or later-line systemic therapies, respectively. The median progression-free survival in Child-Pugh class A patients was nearly equal between first- and second- or later-line therapies (5.2 months; 95% CI 3.7-6.9 for first line, 4.8 months; 95% CI 3.8-5.9 for second or later line, p = 0.933). According to the modified Response Evaluation Criteria in Solid Tumors, the objective response rate of 27 patients (18%) who showed a high burden of intrahepatic lesions (i.e., main portal vein and/or bile duct invasion or 50% or higher liver occupation) at baseline radiological assessment was 41% and similar with that of other population. The present study included 20 patients (13%) with Child-Pugh class B. These patients observed high frequency rates of liver function-related adverse events due to lenvatinib. The 8-week dose intensity of lenvatinib had a strong correlation with liver function according to both the Child-Pugh and albumin - bilirubin scores. CONCLUSION: Lenvatinib had potential benefits for patients with advanced HCC with second- or later-line therapies and a high burden of intrahepatic lesions. Dose modification should be paid increased attention among patients with poor liver function, such as Child-Pugh class B patients.
RESUMEN
Aim: Tolvaptan, an oral vasopressin-2 antagonist, sometimes improves hepatic edema including ascites in patients with decompensated cirrhosis. In this study, we examined the effectiveness and survival advantage in patients with the long-term administration of tolvaptan. Methods: A total of 115 patients with refractory ascites who were treated with tolvaptan were retrospectively analyzed based on their clinical records. Patients with a decrease in body weight of ≥1.5 kg from the baseline on day 7 were determined as responders. Re-exacerbation was defined as a return to the baseline BW, dose escalation of conventional diuretics, or abdominal drainage. Results: Of the 115 patients, 84 were included in this analysis. Response to tolvaptan treatment was observed in 55 out of the 84 patients (65.5%), with a mean weight reduction of 2.52 kg. Multivariate analyses demonstrated that body mass index (≥24) and urinary specific gravity (≥1.018) were significant predictors of the response to tolvaptan. However, cumulative re-exacerbation rates in responders at 6 and 12 months were 42.4 and 60.1%, respectively. Child-Pugh (classification C), HCC complication, and serum sodium levels (≥133 mEq/L) were determined as independent prognostic factors impacting overall survival (OS). Although there were no significant differences in OS between tolvaptan responders and non-responders, the responders without re-exacerbation within 3 months showed significantly longer OS than those with re-exacerbation within 3 months. Conclusion: A persistent therapeutic response, but not early response to tolvaptan, was associated with favorable survival of decompensated cirrhotic patients.

In patients with unresectable hepatocellular carcinoma (HCC) without both macrovascular invasion and extrahepatic metastasis, the initial treatment choice recommended is transarterial chemoembolization (TACE). Before sorafenib came into wide use, TACE had been pointlessly carried out repeatedly. It was in the early 2010s that the concept of TACE refractory was advocated. Two retrospective studies from Japan indicated that conversion from TACE to sorafenib the day after patients were deemed as TACE refractory improved overall survival compared with continued TACE, according to the definition by the Japan Society of Hepatology. Nowadays, phase 3 trials have shown clinical benefits of several novel molecular target agents. Compared with the era of sorafenib, sequential treatments with these molecular target agents have gradually prolonged patients' survival and have become major strategies in patients with HCC. Taking these together, conversion from TACE to systemic therapies at the time of TACE refractory, compared with before, may have a greater impact on survival and may be considered deeper in the decisions-making process in patients with unresectable HCC who are candidate for TACE. Up-to-date information on the concept of TACE refractory is summarized in this review. We believe that the survival of patients with unresectable HCC without both macrovascular invasion and extrahepatic metastasis may be dramatically improved by optimal timing of TACE refractory and switching to systemic therapies.
