Purpose
To compare the efficacy and safety of combined treatment with lenvatinib and transarterial chemoembolization (TACE) versus TACE only in patients with unresectable hepatocellular carcinoma (uHCC).
Methods
Of the 120 patients enrolled in this study, 60 patients received treatment with TACE only, and 60 patients received TACE plus lenvatinib. We retrospectively compared the clinical outcomes including overall survival (OS), progression-free survival (PFS), and tumor response between the two groups. Both PFS and tumor response were based on the modified Response Evaluation Criteria in Solid Tumors (mRECIST). Adverse events were analyzed to assess the safety profiles.
Results
The 1-year and 2-year OS rates were significantly higher in the TACE + lenvatinib group (88.4% and 79.8%) than that in the TACE group (79.2% and 49.2%, p = 0.047). A similar PFS benefit was observed in the TACE + lenvatinib group (1-y PFS rate: 78.4% vs. 64.7%, 2-y PFS rate: 45.5% vs. 38.0%, p < 0.001). The best overall objective response rate (ORR) was also better with TACE + lenvatinib treatment (ORR: 68.3% vs. 31.7%, p < 0.001) and disease control rate (DCR) numerically increased in the TACE + lenvatinib treatment (93.3% vs. 86.7%, p = 0.224). Patients’ liver function remained comparable to baseline in the TACE + lenvatinib group. The most common adverse events were decreased albumin (55.0%), hypertension (48.3%) and decreased platelet count (46.7%) in the TACE + lenvatinib group.
Conclusions
Combination treatment with TACE and lenvatinib may significantly improve clinical outcomes over TACE monotherapy with a manageable safety profile for unresectable HCC. The efficacy of the combination treatment should be validated in prospective studies with a large sample size.
Graphical abstract
Hepatic progenitor cells (HPC) play important roles in both liver regeneration and carcinogenesis. Combined hepatocellular‐cholangiocarcinoma (CHC), a malignant primary liver tumor with poor prognosis, is thought to be of HPC origin. However, the prognostic significance of this etiology is not well defined. Therefore, we retrospectively investigated the relationship of HPC‐related pathological features and long‐term outcome in patients with CHC in our department. In a cohort of 80 patients identified between 1997 and 2003, including 70 patients who underwent resection with curative intent, overall survival (OS) and disease‐free survival (DFS) were correlated with the proliferative activity of nontumor ductular reaction (DR) and the expression levels of HPC and biliary markers including α‐fetoprotein (AFP), keratin 7 (K7), keratin 19 (K19), oval cell (OV)‐6, epithelial cell adhesion molecule (EpCAM), and c‐Kit in both tumor and nontumor liver. We found that nontumor ductular reactions (DRs), specifically the proliferating cell nuclear antigen (PCNA) labeling index of the ductular reaction (PI‐DR), a surrogate for transit‐amplifying compartments, was an independent prognostic factor for both OS and DFS. By contrast, intratumoral expression of only one marker, absence of AFP, was associated with OS. PI‐DR was also independently associated with synchronous “multicentric occurrence” in hepatocellular carcinoma components, a feature of CHC that may predispose to metachronous multifocal tumorigenesis. Conclusion: Proliferative ductular reaction related to HPC activation is associated with recurrence of CHC. Background HPC activation is strongly associated with multifocal occurrence and related tumor recurrence, highlighting the critical role of background liver disease, a “field effect,” in the recurrence of CHC.

The severity of CSPH, corresponding to different PVP levels, could be used to stratify patients with Child-Pugh grade A cirrhosis and to predict the incidence of PHLF. Patients with severe CSPH or a NLR of 2·8 or above were more likely to develop persistent PHLF after partial hepatectomy.
Surgical resection could be considered in part of patients with advanced HCC (BCLC stage C), with low mortality, acceptable morbidity and favorable survival benefits. These results imply that BCLC recommendations for treatment schedules of advanced HCC need to be re-evaluated.
Krüppel-like factor 8 (KLF8) plays important role in cell cycle and oncogenic transformation. Here we report the mechanisms by which KLF8 crosstalks with Wnt/β-catenin signaling pathway and regulates hepatocellular carcinoma (HCC) cells proliferation. We show that overexpression of KLF8 and nucleus accumulation of β-catenin in the human HCC samples are positively correlated. More importantly, KLF8 protein levels plus nucleus accumulation of β-catenin levels were significantly elevated in high-grade HCC compared to low-grade HCC. Using HCC HepG2 cells we find that, on the one hand both protein and mRNA of KLF8 are up-regulated under Wnt3a stimulation, on the other hand overexpression of KLF8 increases the cytoplasm and nucleus accumulation of β-catenin, recruits p300 to β-catenin/T-cell factor 4 (TCF4) transcription complex, enhances TOP flash report gene transcription, and induces Wnt/β-catenin signaling target genes c-Myc, cyclin D1 and Axin1 expression. Knockdown of KLF8 using shRNA inhibits Wnt3a induced transcription of TOP flash report gene and expression of c-Myc, cyclin D1 and Axin1. Knockdown of β-catenin by shRNA rescues the enhanced HepG2 and Hep3B cells proliferation ability induced by overexpression of KLF8.
The aim of the study was to investigate and compare the clinical manifestations between HLA-B27(+) and HLA-B27(-) ankylosing spondylitis (AS) patients in order to obtain knowledge of the impact of HLA-B27 status on AS, and to inform clinical treatment. A nationwide epidemiological investigation was performed from November 2008 to October 2010. The demographic data and clinical characteristics, and the status of HLA-B27 were collected using questionnaires and laboratory assay, respectively. A total of 2144 patients (78.5% males and 78.4% HLA-B27(+) AS patients) participated in this study. The percentages of males, patients with family history, and involvement of lumbar spine, thoracic spine and hip joints, were observed to be significantly higher in the HLA-B27(+) AS patients than in their HLA-B27(-) AS peers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
