PURPOSE Lenvatinib (LEN) is a first-line therapy for patients with advanced hepatocellular carcinoma (HCC); however, it has shown modest survival benefits. Therefore, we aimed to compare clinical outcomes of LEN combined with transarterial chemoembolization (LEN-TACE) versus LEN monotherapy in patients with advanced HCC. MATERIALS AND METHODS This was a multicenter, randomized, open-label, parallel group, phase III trial. Patients with primary treatment-naive or initial recurrent advanced HCC after surgery were randomly assigned (1:1) to receive LEN plus on-demand TACE (LEN-TACE) or LEN monotherapy. LEN was initiated within 3 days after random assignment (initial dose: 12 mg once daily for patients ≥ 60 kg; 8 mg once daily for patients < 60 kg). TACE was initiated one day after LEN initiation. The primary end point was overall survival (OS). RESULTS Between June 2019 and July 2021, a total of 338 patients underwent random assignment at 12 centers in China: 170 to LEN-TACE and 168 to LEN. At a prespecified event-driven interim analysis after a median follow-up of 17.0 months, the median OS was significantly longer in the LEN-TACE group (17.8 v 11.5 months; hazard ratio, 0.45; P < .001). The median progression-free survival was 10.6 months in the LEN-TACE group and 6.4 months in the LEN group (hazard ratio, 0.43; P < .001). Patients in the LEN-TACE group had a higher objective response rate according to the modified RECIST (54.1% v 25.0%, P < .001). Multivariable analysis revealed that portal vein tumor thrombus and treatment allocation were independent risk factors for OS. CONCLUSION The addition of TACE to LEN improves clinical outcomes and is a potential first-line treatment for patients with advanced HCC.

Aims To investigate the efficacy and safety of lenvatinib and idarubicin‐loaded drug‐eluting beads transarterial chemoembolization (IDADEB‐TACE) in primary advanced hepatocellular carcinoma (HCC). Methods This retrospective study included patients with primary advanced HCC who received either lenvatinib monotherapy or lenvatinib plus IDADEB‐TACE as first‐line treatment from September 2019 to September 2020 at three institutes. Overall survival (OS), time to progression (TTP), objective response rate (ORR), and adverse events were compared. Propensity score‐matching was used to reduce the influence of confounding factors on the outcomes. Results The study reviewed 118 patients who received lenvatinib plus IDADEB‐TACE (LIDA group) and 182 who received lenvatinib alone (LEN group). After propensity score‐matching, 78 pairs of patients remained. Compared to patients in the LEN group, those in the LIDA group had better post‐treatment ORR (57.7% vs. 25.6%, p < 0.001, respectively), median OS and TTP (15.7 vs. 11.3 months, hazard ratio [HR] = 0.50, p < 0.001; 8.0 vs. 5.0 months, HR = 0.60, p = 0.003, respectively), 6‐ and 12‐month OS rates (88.5% vs. 71.4%; 67.6% vs. 43.4%, respectively), and progression‐free rates at 6 and 12 months (60.3% vs. 42.3%; 21.1% vs. 10.3%, respectively). Vascular invasion, α‐fetoprotein level, and treatment type were independent OS predictors, and vascular invasion and treatment type were independent TTP predictors. Incidences of nausea/vomiting, fever, abdominal pain, and increased ALT/AST were higher in the LIDA group than in the LEN group. Conclusions Lenvatinib plus IDADEB‐TACE is well‐tolerated and more effective than lenvatinib monotherapy in patients with advanced HCC.

Objective To develop a prognostic model for post-transjugular intrahepatic portosystemic shunt (TIPS) patients with hepatocellular carcinoma (HCC) beyond the Milan criteria treated by transarterial chemoembolization (TACE). Design Between January 2013 and January 2020, 512 patients with HCC beyond the Milan criteria who underwent TACE after TIPS were retrospectively recruited from 15 tertiary centers. Patients were randomly sorted into a training set (n = 382) and a validation set (n = 130). Medical data and overall survival were assessed. A prediction model was developed using multivariate Cox regression analyses. Predictive performance and discrimination were evaluated and compared with other prognostic models. Results Vascular invasion, log10(AFP), 1/creatinine, extrahepatic spread, and log10(ALT) were the most significant prognostic factors of survival. These five parameters were included in a new VACEA score. This score was able to stratify patients in the training set into four distinct risk grades whose median overall survival were 25.2, 15.1, 8.9, and 6.2 months, respectively. The 6-month, 1-year, 2-year, and 3-year AUROC values and C-index of the VACEA model were 0.819, 0.806, 0.779, 0.825, and 0.735, respectively, and higher than those of other seven currently available models in both the training and validation sets, as well as in different subgroups. Conclusion The VACEA score could stratify post-TIPS patients with HCC beyond the Milan criteria treated by TACE and help to identify candidates who benefit from this treatment. Key Points • Vascular invasion, AFP, creatinine, extrahepatic spread, and ALT were independent significant prognostic factors of survival for HCC patients who underwent TACE after TIPS. • Our new model, named VACEA score, can accurately predict prognosis at the individual level and stratify patients into four distinct risk grades. • The VACEA model showed better prognostic discrimination and calibration than other current TACE-/TIPS-specific models

Background Next-generation sequencing (NGS) is maturely applied for gene fusion detection. Although tumor fusion burden (TFB) has been identified as an immune marker for cancer, the relationship between these fusions and the immunogenicity and molecular characteristics of gastric cancer (GC) patients remains unclear. GCs have different clinical significance depending on their subtypes, and thus, this study aimed to investigate the characteristics and clinical relevance of TFB in non-Epstein–Barr-virus-positive (EBV+) GC with microsatellite stability (MSS). Methods A total of 319 GC patients from The Cancer Genome Atlas stomach adenocarcinoma (TCGA-STAD) and a cohort of 45-case from ENA (PRJEB25780) were included. The cohort characteristics and distribution of TFB among the patients were analyzed. Additionally, the correlations of TFB with mutation characteristics, pathway differences, relative abundance of immune cells, and prognosis were examined in the TCGA-STAD cohort of MSS and non-EBV (+) patients. Results We observed that in the MSS and non-EBV (+) cohort, the TFB-low group exhibited significantly lower gene mutation frequency, gene copy number, loss of heterozygosity score, and tumor mutation burden than in the TFB-high group. Additionally, the TFB-low group exhibited a higher abundance of immune cells. Furthermore, the immune gene signatures were significantly upregulated in the TFB-low group, 2-year disease-specific survival was markedly increased in the TFB-low group compared with to the TFB-high group. The rates of TFB-low cases were significantly higher TFB-than high cases in durable clinical benefit (DCB) and response groups with pembrolizumab treatment. Low TFB may serve as a predictor of GC prognosis, and the TFB-low group exhibits higher immunogenicity. Conclusion In conclusion, this study reveals that the TFB-based classification of GC patient may be instructive for individualized immunotherapy regimens.

Purpose: To investigate the effectiveness and safety of the combination of sorafenib and drug-eluting bead transarterial chemoembolization (DEB-TACE) in the treatment of early intrahepatic stage-progressed advanced hepatocellular carcinoma (ISPA-HCC).Methods: This study was approved by the ethics committees of six tertiary medical centers in China. Between October 2017 and October 2020, 213 patients with advanced HCC received either sorafenib combined with on-demand DEB-TACE (DTS group, n = 103) or sorafenib monotherapy (S group, n = 110). Overall survival (OS), time to progression (TTP), local tumor response, and adverse events (AEs) were compared between the two groups.Results: The AEs of patients were similar between the DTS and S groups. The post-treatment partial response, objective response, and disease control rates were significantly higher in the DTS group than in the S group (51.5% vs. 23.6%; 56.3% vs. 25.5%; 77.7% vs. 56.4%, respectively). The median OS was significantly longer in the DTS group than in the S group (16.3 vs. 10.0 months; hazard ratio [HR] = 0.43; P < 0.001), as was the TTP (6.7 vs. 4.3 months; HR = 0.60; P = 0.001). In the DTS group, patients who received ≥2 sessions of DEB-TACE benefited more than those who received two sessions of DEB-TACE. Multivariate analysis revealed that the α-fetoprotein level and treatment allocation were independent predictors of OS and TTP.Conclusion: The combination of sorafenib and DEB-TACE is safe and effective for the treatment of early ISPA-HCC.
