Background. Accumulating evidence has suggested that Nei-like DNA glycosylase 3 (NEIL3) is associated with human tumors. However, there are few studies on the role of NEIL3 in hepatocellular carcinoma (HCC). The aim of this study was to investigate the expression profile of NEIL3 and its clinical relevance in HCC. Materials and Methods. A total of 130 HCC and corresponding nontumor tissues were collected to perform immunohistochemistry (IHC). The clinical relevance and prognostic value of NEIL3 in HCC were analyzed by the chi-square test, Kaplan–Meier analysis, the Cox proportional hazard model, and nomogram. Results. IHC showed that the NEIL3 protein level was remarkably upregulated in tumor tissues compared with nontumor tissues (fold change = 1.24; P < 0.001 ). High NEIL3 expression was significantly correlated with BCLC stage ( P = 0.004 ) and TNM stage ( P = 0.005 ). Overall survival (OS) and disease-free survival (DFS) rates in the high NEIL3 expression group were significantly worse than those in the low NEIL3 expression group ( P = 0.007 and P = 0.004 , respectively). Furthermore, subgroup analysis showed that high NEIL3 expression predicted worse OS and DFS for HCC patients with advanced TNM stage, poorly differentiated tumor, HBsAg positive, or cirrhosis. Multivariate analysis and the prognostic nomograms revealed that tumor NEIL3 level may serve as a promising prognostic indicator for OS and DFS in HCC patients. Conclusion. Our findings suggested that NEIL3 might be a potential prognosis assessment marker and therapeutic target for HCC patients.

N-myc downstream-regulated gene 3 (NDRG3), an important member of the NDRG family, is involved in cell proliferation, differentiation, and other biological processes. The present study analyzed NDRG3 expression in hepatocellular carcinoma (HCC) and explored the relationship between expression of NDRG3 in HCC patients and their clinicopathological characteristics. We performed quantitative real-time reverse-transcription polymerase chain reaction (qRT-PCR) analysis and immunohistochemistry (IHC) analyses on HCC tissues to elucidate NDRG3 expression characteristics in HCC patients. Kaplan–Meier survival curve and Cox regression analyses were used to evaluate the prognoses of 102 patients with HCC. The results revealed that compared with non-tumor tissues, HCC tissues showed significantly higher NDRG3 expression. In addition, our analyses showed that NDRG3 expression was statistically associated with tumor size (P=0.048) and pathological grade (P=0.001). Survival analysis and Kaplan–Meier curves revealed that NDRG3 expression is an independent prognostic indicator for disease-free survival (P=0.002) and overall survival (P=0.005) in HCC patients. The data indicate that NDRG3 expression may be considered as a oncogenic biomarker and a novel predictor for HCC prognosis.

Abstract Background: NBEAL2 is a member of the BEACH domain–containing protein (BDCP) family and little is known about the relationship between NBEAL2 and malignancy.Methods: We downloaded the Gene expression profiles and clinical data of Liver hepatocellular carcinoma(LIHC) form the Cancer Genome Atlas (TCGA) dataset. The expression difference of NBEAL2 in LIHC tissues and adjacent nontumor tissues was analyzed by R software. The relationship between NBEAL2 expression and clinicopathological parameters was evaluate by Chi-square test. The effect of NBEAL2 expression on survival were assessed by Kaplan–Meier survival analysis and Cox proportional hazards regression model. GSEA was used to explore the potential molecular mechanism of NBEAL2 in LIHC.Results: Up-regulation of NBEAL2 expression was detected in the LIHC tissue compared with adjacent nontumor tissues(P < 0.001). The chi-square test showed that no significant correlation between the expression level of NBEAL2 and various clinicopathological parameters (including T, N and M classifications) were detected. The Kaplan–Meier curves suggested that lower NBEAL2 expression was related with poor prognosis. The results of Multivariate analysis revealed that a lower expression of NBEAL2 in LIHC was an independent risk of poor overall survival (HR, 8.873; 95% CI, 1.159-67.936; P = 0.035). GSEA suggested that multiple tumor-related metabolic pathways were evidently enriched in samples with the low-NBEAL2 expression phenotype. Conlusion: NBEAL2 might act as an tumor suppressor gene in the progression of LIHC but the precise role of NBELA2 in LIHC needs further vertification.

Abstract Background: Previous studies have demonstrated that microRNAs (miRNAs) played a crucial role in various diseases, including cancers. The aim of the study was to evaluate the clinical significance of miR-124 in patients with cholangiocarcinoma (CCA).Methods: The expression pattern of miR-124 was detected in CCA tissues using quantitative reserve transcription polymerase chain reaction (qRT-PCR). The correlation of miR-124 expression with clinicopathological features and overall survival of patients were explored using chi-square test, Kaplan-Meier methods and Cox regression analyses.Results: The miR-124 expression level was strong down-regulated in CCA tissues compared with normal para-cancerous tissues (P<0.001). Moreover, aberrant miR-124 expression was significantly associated with differentiation (P=0.045) and lymph node metastasis (P=0.040). In addition, Kaplan-Meier method and log-rank test revealed that patients with low miR-124 expression has a poorer overall survival compared with those with high miR-124 expression (P=0.002). Furthermore, multivariate analysis confirmed that miR-124 expression (P=0.006; HR=2.006; 95%CI: 1.224-3.289) was an independent prognostic indicator in CCA.Conclusions: Collectively, our results defined miR-124 expression plays important roles in CCA patients. MiR-124 expression might used as a valuable prognostic biomarker for patients with CCA.

Aims: Lysine acetyltransferase 6B (KAT6B), is a histone acetyltransferase implicated to have a role in tumor suppression. However, the relationship between KAT6B and hepatocellular carcinoma (HCC) is unclear. The purpose of this study was to detect the expression of KAT6B in HCC tissues and analyze its connection with the clinicopathological features of HCC. Methods: First, we performed immunohistochemical staining on 250 HCC tissues and 222 non-tumor liver tissues to examine the expression of KAT6B.Then the relation between KAT6B expression and clinicopathological parameters was analyzed by chi-square test, and the overall survival analysis was conducted by Kaplan-Meier survival method. In addition, based on the Oncomine expression array online and the UALCAN database, we compared KAT6B expression differences between normal liver tissues and HCC tissues more broadly. Results: Compared with normal tissues, KAT6B expression was significantly lower in HCC tissues. Low KAT6B expression was found to be related to gender, AFP level, and tumor size. According to the online database, KAT6B expression was found to be decreased in HCC tissues and high in normal tissues. Conclusions: Lower expression of KAT6B is associated with poor prognosis of HCC, and KAT6B may be a potential tumor suppressor in liver cancer.

Abstract Background: Rab25 was indicated to be involved in several human tumors. However, the clinical significance of Rab25 in hepatocellular carcinoma (HCC) was still unclear. The purpose of this study was to investigate the expression and prognostic value of Rab25 in HCC.Methods: The relative mRNA expression levels of Rab25 in HCC tissues and adjacent normal tissues were detected by quantitative real-time polymerase chain reaction (qRT-PCR). Chi-square test was used to analyze the relationship between Rab25 expression and clinical characteristics of patients. The prognostic value of Rab25 in HCC was estimated through Kaplan-Meier method and cox regression analysis.Results: Rab25 gene expression level was significantly higher in HCC tissues than that in normal tissues (P<0.001). Importantly, the increased Rab25 expression was closely associated with TNM stage (P=0.024), metastasis (P=0.022) and invasion classification (P=0.039). Moreover, patients with high Rab25 expression tended to have obviously shorter overall survival than those with low expression of Rab25 (log rank test, P<0.001) via Kaplan-Meier analysis. Univariate and multivariate cox regression analyses revealed that Rab25 was an independent prognostic factor of HCC.Conclusions: Rab25 is up-regulated in HCC and contributes to the progression of this tumor. What’s more, Rab25 may be a potential bio-marker for the prognosis of HCC.

e23034 Background: In kidney cancer, some important prognostic factors of survival are known and inflammation plays a key role. It has been proven that cancer progress is not only determined by the characteristics of the tumor but also by the response of the host. It is known that a high RNL has been identified as an independent prognostic factor associated to poor survival in several/different types of cancer, including breast cancer, colon cancer, gastric cancer, mesothelioma and pancreas. The primary aim was to evaluate if RNL can be used as a prognostic indicator of SLP in patients with advanced CCR with 1st line treatment with tirosin-kinasa inhibitors. The secondary aim was to evaluate whether there was a relationship between prognostic factors, smoking habits, BMI, anemia, calcemia, KPS and nephrectomized patients as opposed to those who were not operated with RNL and SLP. Methods: Retrospective and analytical study. The medical histories from patients with metastatic kidney cancer diagnosis were analyzed as well as those who were undergoing treatment with Sunitinib and Pazopanib. The cut value of > ó < 3 was taken as a reference point for RNL. Overall survival analysis will be evaluated through the Kaplan-Meier curve and the meaning will be verified by the log-rank test. The multivariate analysis will be done through the Chi-square test. Results: A total of 65 patients were included in this study. 50 patients (75.38%) received treatment with Sunitinib and 15 patients (24.62%) with Pazopanib. It was observed that RNL < 3 was correlated with a higher SLP 21,6 months vs 8.9 months, p = 0,00002 and it was statistically significant. In subgroup analysis, those patients with normal values of corrected calcium the survival was 20 months vs 12, 2 months (p: 0.01), non-smokers 21 months vs 12 months (p: 0.05), KPS > 1 17,72 months Vs 8,8 months (p: 0.03) and a RNL < 3 showed a higher survival in a statistically significant way. There were no differences in survival when we performed the anemia analysis, BMI, smoking habits and KPS 0 to 1. Conclusions: We can conclude that those patients with RNL < 3 and who had already undergone treatment with ITK revealed a better SLP in a statistically significant way.

Emerging evidence are accumulating that long noncoding RNAs (lncRNAs) have recently been identified to participate in various cellular processes. Terminal differentiation induced ncRNA (TINCR) is a newly identified lncRNA with its functional roles not fully elucidated in human malignancy. The current study aims to identify the clinical significance of TINCR in prognosis and malignant progression of hepatocellular carcinoma (HCC). TINCR expression in HCC specimens at various stages of tumorigenesis were measured by quantitative real-time RT PCR (qRT-PCR). The matched para-carcinoma tissues were used as controls. The associations of TINCR with clinicopathological characteristics, disease-free survival (DFS) and overall survival (OS) of patients were further evaluated. Results revealed that high TINCR expression was significantly correlated with tumor size (P=0.005), tumor differentiation status (P=0.017), TNM stage (P=0.010), and vascular invasion (P=0.004). Moreover, Kaplan–Meier analysis demonstrated that TINCR was correlated to both DFS and OS in HCC cohorts. Patients with high TINCR expression tended to have worse prognosis. Multivariate Cox regression analysis indicated that TINCR was an independent poor prognostic indicator for DFS (HR =1.32, 95% CI: 1.00–1.57, P=0.000) and OS (HR =1.57, 95% CI: 1.30–1.86, P=0.004) in HCC. TINCR was demonstrated as a direct target of miR-137 and miR-133a, and was suppressed by miR-137/miR-133a. These results provide the first evidence that the expression of TINCR in HCC may play an oncogenic role in HCC differentiation, invasion, and metastasis. miR-137/miR-133a-TINCR pathway may serve as a promising target for tumor recurrence and prognosis of patients with HCC.

AbstractBackgroundNormal platelet (PLT) plays a vital role in thrombosis, the inflammatory response, and liver regeneration. The effect of abnormal PLT counts has been seldom explored in hepatocellular carcinoma (HCC); hence, this investigation was conducted to evaluate the prognostic importance of preoperative abnormal PLT count in HCC patients after liver resection retrospectively.MethodologyThe PLT counts were determined using Sysmex XT-1800i automated hematology analyzer and its matching reagents. Patients were divided into two groups: a normal PLT group and an abnormal PLT group. Chi-square test, Kaplan–Meier method, and Cox univariable and multivariable regressions were utilized to analyze the data.ResultsA total of 391 HCC patients who underwent liver resection were included in this study. The overall survival (OS) rates were 59% and 31%, and the median survival time was 69 months and 31 months in the normal and abnormal PLT groups, respectively. The PLT level was associated with OS in univariate and multivariate analyses (hazard ratio [HR], 1.991 [95% confidence interval {CI}, 1.412–2.808] and HR, 2.217 [95% CI, 1.556–3.159], respectively).ConclusionsPatients with normal PLT had a better outcome in terms of OS. The results suggested that abnormal PLT count is an independent prognostic factor for HCC patients after liver resection.

Abstract Background Hepatocellular carcinoma (HCC) is a primary malignancy of the hepatocyte with high risk of invasion, metastasis and poor prognosis, which leads to a high mortality rate in recent years. This study aims to investigate the independent prognosis factors of DFS(disease free survival) in hepatocellular carcinoma patients after radical hepatectomy.Methods This study retrospectively analyzed 358 patients admitted to the 1st Affiliated Hospital of Anhui Medical College from December 2009 to December 2014. Categorical variables were analyzed by chi-square test. The survival curve was plotted by kaplan-meier method and tested by log-rank method. Univariate and multivariate Cox regression analyses were performed to determine the prognostic factors.Results Among the 344 patients with liver cancer, 298 cases (86.63%) are young patients (< 70 years), and 46 cases (13.37%) were elderly patients (≥ 70 years). There were no significant difference in gender, smoking history, alcohol consumption history, Body Mass Index (BMI), number of cancer nodules, tumor diameter, differentiation degree and TNM stage between the young and elderly groups (P > 0.05). However, history of hepatitis B and liver cirrhosis were more common in young patients than elderly (P=0.017, P༝0.000). The Kaplan-Meier curves indicated that elderly patients (higher than 70 years), TNM I-II stage and no history of hepatitis B had longer DFS. The univariate and multivariate analyses showed that age, TNM stage, History of hepatitis B were the independent factors for DFS.Conclusions Our findings suggested that age, TNM stage, history of hepatitis B were independent factors for predicting DFS of primary hepatocellular carcinoma patients. Patients older than 70 years had a better prognosis than young patients. Patients with early TNM stage and no history of hepatitis B had longer DFS.

Abstract Background CKLF Like Marvel Transmembrane Domain Containing 1 (CMTM1) plays a role in breast cancer and lung cancer, but studies on the occurrence and development of CMTM1 in hepatocellular carcinoma (HCC) have not been reported. Methods The Cancer Genome Atlas (TCGA) database and immunohistochemistry (IHC) were used to detect CMTM1 expression in HCC tissues. The relationship between CMTM1 expression and the clinicopathological characteristics of HCC patients was analyzed by chi-square test, and the relationship between CMTM1 expression and the prognosis of HCC patients was tested by the Kaplan–Meier model. Results Bioinformatics analysis showed that the mRNA expression of CMTM1 was upregulated in HCC tissues, and low expression of CMTM1 is associated with longer disease-free survival in patients with HCC. Similarly, the survival time of HCC patients in CMTM1 high expression group was significantly shorter than that in CMTM1 low expression group. IHC detection indicated that CMTM1 protein was highly expressed in both HCC and adjacent non-tumor tissues, with a positive expression in 84% (63/75) of HCC tissues and 89.3% (67/75) of adjacent non-tumor tissues. Moreover, CMTM1 expression was related to family history and TNM stage of HCC patients (P < 0.05), but had no relationship with other clinicopathological characteristics. The survival analysis based on IHC results showed that the prognosis of HCC patients in CMTM1 negative group was significantly poorer than that in CMTM1 positive group (P < 0.05). Conclusion CMTM1 has a high expression in HCC tissues and is related to the prognosis of HCC patients.
