BACKGROUND: Interferon-based antiviral therapies against hepatitis C virus (HCV) infection have been shown to reduce the incidence of hepatocellular carcinoma (HCC) in patients with sustained viral response (SVR). Recently, direct-acting antivirals (DAAs) have been proven to be much more effective in achieving SVR than interferon-based therapies. However, whether DAAs can efficiently prevent the occurrence of HCC after SVR remains controversial. To clarify this issue, we analyzed the clinical features of patients in whom HCC developed after achievement of SVR with DAAs for chronic HCV infection...

Ewing's sarcoma (ES) is a rare tumor that is more frequent in pediatric and adolescent age groups. In the past few decades, long-term survival in affected patients has improved due to the success of multimodal therapy. However, long-term survival is inevitably restricted by the late side-effects of chemotherapy. Besides, early metastasis also contributes to the poor prognosis of ES. Recently, traditional Chinese medicines (TCMs) have increasingly attracted interest due to the promising clinical results and fewer side-effects for the treatment of cancers...

The treatment approach for hepatocellular carcinoma (HCC) depends on the stage and extent of disease, the severity of the underlying liver disease, and the overall performance status of the patient. Treatment consists of 4 main strategies: surgery (eg, resection and liver transplant), locoregional procedures (eg, ablation and transarterial embolization), systemic therapies, and best supportive care. For patients with early-stage tumors, surgical treatment or ablation can be curative. Patients with intermediate-stage disease can be candidates for embolization, administered as either transarterial chemoembolization (TACE) or transarterial radioembolization (TARE)...

Early recurrence is common after curative hepatectomy for hepatocellular carcinoma and is associated with poor prognosis. This study aimed to identify risk factors of early recurrence after curative hepatectomy in hepatocellular carcinoma. Overall, 63 patients who underwent curative hepatectomy for hepatocellular carcinoma were enrolled. Patients were divided into the early recurrence group, who developed recurrence within 12 months after hepatectomy (n = 10), and the non-early recurrence group (n = 53)...

Detection of early hepatocellular carcinoma (HCC) is responsible for increasing survival rates in up to 40%. One-class classifiers can be used for modeling early HCC in multidetector computed tomography (MDCT), but demand the specific knowledge pertaining to the set of features that best describes the target class. Although the literature outlines several features for characterizing liver lesions, it is unclear which is most relevant for describing early HCC. In this paper, we introduce an unconstrained GA feature selection algorithm based on a multi-objective Mahalanobis fitness function to improve the classification performance for early HCC...

Percutaneous treatment of hepatocellular carcinoma (HCC) encompasses a vast range of techniques, including monopolar radiofrequency ablation (RFA), multibipolar RFA, microwave ablation, cryoablation and irreversible electroporation. RFA is considered to be one of the main curative treatments for HCC of less than 5 cm developing on cirrhosis, together with surgical resection and liver transplantation. However, controversies exist concerning the respective roles of ablation and liver resection for HCC of less than 3 to 5 cm on cirrhosis...

Hepatocellular carcinoma (HCC) is a complex disease with a multi-step carcinogenic process from preneoplastic lesions, including cirrhosis, low-grade dysplastic nodules (LGDNs), and high-grade dysplastic nodules (HGDNs) to HCC. There is only an elemental understanding of its molecular pathogenesis, for which a key problem is to identify when and how the critical transition happens during the HCC initiation period at a molecular level. In this work, for the first time, we revealed that LGDNs is the tipping point (i...

A very low 5-year survival rate among hepatocellular carcinoma (HCC) patients is mainly due to lack of early stage diagnosis, distant metastasis and high risk of postoperative recurrence. Hence ascertaining novel biomarkers for early diagnosis and patient specific therapeutics is crucial and urgent. Here, we have performed a comprehensive analysis of the expression data of 423 HCC patients (373 tumors and 50 controls) downloaded from The Cancer Genome Atlas (TCGA) followed by pathway enrichment by gene ontology annotations, subtype classification and overall survival analysis...

Cholangiocarcinoma (CCA) is the second most common liver cancer and it is associated with a poor prognosis. CCA can be divided into intrahepatic, hilar and distal. Despite the subtype, the median survival is 12-24 months without treatment. Liver transplantation (LT) is worldwide recognized as a curative option for hepatocellular carcinoma. On the other hand, the initial results for LT for CCA were very poor mainly due to a lack of adequate patient selection. In the last two decades, improvement has been made in the management of unresectable hilar CCA, and the results of LT after neoadjuvant chemoradiation have been shown to be promising...

Hepatocellular carcinoma (HCC) is a heterogeneous tumour associated with poor prognostic outcome. Caveolin-1 (CAV1), a membrane protein involved in the formation of caveolae, is frequently overexpressed in HCC. Transforming growth factor-beta (TGF-β) is a pleiotropic cytokine having a dual role in hepatocarcinogenesis: inducer of apoptosis at early phases, but pro-tumourigenic once cells acquire mechanisms to overcome its suppressor effects. Apoptosis induced by TGF-β is mediated by upregulation of the NADPH oxidase NOX4, but counteracted by transactivation of the epidermal growth factor receptor (EGFR) pathway...

BACKGROUND Adequate portal venous flow is required for successful liver transplantation. Reduced venous flow and blood flow 'steal' by collateral vessels are a concern, and when there is a prominent splenorenal shunt present, ligation of the left renal vein has been recommended to improve portal venous blood flow.

Achiral Mannich-type curcumin analogs have been synthetized and assayed for their cytotoxic activity. The anti-proliferative and cytotoxic activity of curcuminoids has been tested on human non-small-cell lung carcinoma (A549), hepatocellular carcinoma (HepG2) and pancreatic cancer cell line (PANC-1). Based on the highest anti-proliferative activity nine drug candidates were further tested and proved to cause phosphatidylserine exposure as an early sign of apoptosis. Curcumin analogs with the highest apoptotic activity were selected for mechanistic studies in the most sensitive PANC-1 cells...

Chronic fibrotic liver disease caused by viral or metabolic etiologies is a high-risk condition for developing hepatocellular carcinoma (HCC). Even after complete HCC tumor resection or ablation, the carcinogenic tissue microenvironment in the remnant liver can give rise to recurrent de novo HCC tumors, which progress into incurable, advanced-stage disease in the majority of patients. Thus, early detection and prevention of HCC development is, in principle, the most impactful strategy to improve patient prognosis...

BACKGROUND & AIMS: The Barcelona Clinic Liver Cancer (BCLC) guidelines recommend resection for very early and early single hepatocellular carcinoma (HCC) patients. It is not known whether a delay in resection from the time of diagnosis (the time-to-surgery (TTS), i.e., the elapsed time from diagnosis to surgery) affects outcomes. We aim to evaluate the impact of TTS on the recurrence and survival outcomes. METHODS: All patients resected for BCLC stage 0-A single HCC from 2006 to 2016 were studied to evaluate the impact of TTS on recurrence rate, recurrence-free survival (RFS), transplantability following recurrence, and intention-to-treat overall survival (ITT-OS)...

Hepatocellular carcinoma (HCC) is the most prevalent primary liver cancer worldwide, and the survival rates of patients with HCC remains quite low after 5years. Long non-coding RNAs (LncRNAs) are a novel class of non-coding RNAs that are capable of regulating gene expression at various levels. Recent works have demonstrated that lncRNAs are often dysregulated in HCC, and the dysregulation of some of these lncRNAs are associated with the clinicopathological features of HCC. They regulate cell proliferation, apoptosis, autophagy, Epithelial-Mesenchymal Transition (EMT), invasion and metastasis of HCC by modulating gene expression and cancer-related signaling pathways, and thus contribute to the onset and progression of HCC...

Although prognostic markers for early estrogen receptor (ER)-positive breast cancer have been extensively developed, predictive markers for adjuvant endocrine therapy are still lacking. Focusing on the mechanisms underlying endocrine resistance, we investigated whether the endocrine sensitivity of ER-positive breast cancer cells was correlated with the expression of aspartate-β-hydroxylase (ASPH), which is involved in the development of hepatocellular carcinoma. ASPH expression in ER-positive and tamoxifen-resistant breast cancer cells was upregulated by the MAPK and phosphoinositide-3 kinase (PI3K) pathways, which both play pivotal roles in endocrine resistance...

BACKGROUND/AIM: Assessment of liver function is essential for management of hepatocellular carcinoma (HCC). Recently, albumin-bilirubin (ALBI) grade has been reported as a useful tool for assessing hepatic reserve in patients with HCC. The objective of this study was to determine whether ALBI grade could be used to predict the overall survival of very early-stage HCC patients treated with radiofrequency ablation (RF ablation). METHODS: A cohort of 368 patients with very early-stage HCC treated with RF ablation was retrospectively analyzed...
