ABSTRACT

Extracellular vesicle-derived microRNAs (EV-miRNAs) are promising circulating biomarkers for chronic liver disease. In this study, we explored the potential significance of plasma EV-miRNAs in non-hepatitis B-, non-hepatitis C-related HCC (NBNC-HCC). We compared, using the NanoString method, plasma EV-miRNA profiles between NBNC-HCC and control groups including patients with non-alcoholic fatty liver disease (NAFLD) and healthy controls. The differentially expressed EV-miRNAs were validated in another set of plasma samples by qRT-PCR. A total of 66 significantly differentially expressed EV-miRNAs between the HCC and the control groups were identified in the discovery set. In the validation cohort, including plasma samples of 70 NBNC-HCC patients, 70 NAFLD patients, and 35 healthy controls, 5 plasma EV-miRNAs were significantly elevated in HCC, which included miR-19-3p, miR-16-5p, miR-223-3p, miR-30d-5p, and miR-451a. These miRNAs were found to participate in several cancer-related signaling pathways based on bioinformatic analysis. Among them, EV-miR-19-3p exhibited the best diagnostic performance and displayed a high sensitivity for detecting alpha-fetoprotein-negative HCC and early-stage HCC. In multivariate analysis, a high EV-miR-19-3p level was demonstrated as an independently unfavorable predictor of overall survival in patients with NBNC-HCC. In conclusion, our data have indicated, for the first time, that EV-miR-19-3p could serve as a novel circulating biomarker for the diagnosis and prognosis of NBNC-HCC.

ABSTRACT

Aberrantly expressed circulating microRNAs (miRNAs) have been demonstrated to have a crucial role in the diagnosis and prognostication of various cancers, including hepatocellular carcinoma (HCC). This research aimed to examine the role of specific miRNAs in predicting the outcomes for individuals with hepatitis B virus (HBV)-related HCC treated with transarterial chemoembolization (TACE). Stored serum specimens collected prior to the first TACE procedure were employed to determine the expression of serum miR-122, miR-221, and miR-224 using quantitative real-time PCR analysis. The study included 100 HCC patients (84% males, with an average age of 60 years) who were treated with TACE. Throughout the median follow-up spanning 18.5 months (within a range of 3 to 60 months), 42 (42.0%) patients met the criteria of TACE refractoriness. Through multivariate analysis, elevated expressed miR-221 (≥4.0 log10 copies) and advanced HCC staging were identified as independent factors related to TACE refractoriness and short overall survival. However, serum miR-122 and miR-224 levels were not linked to treatment response or overall survival. These findings underscored the potential of incorporating pretreatment levels of serum miR-221 into the established tumor staging to enhance the accurate assessment of TACE responsiveness and prognostic outcome of patients with HCC.

ABSTRACT

PURPOSE: Detection of hepatocellular carcinoma (HCC) is crucial during surveillance by ultrasound. We previously developed an artificial intelligence (AI) system based on convolutional neural network for detection of focal liver lesions (FLLs) in ultrasound. The primary aim of this study was to evaluate whether the AI system can assist non-expert operators to detect FLLs in real-time, during ultrasound examinations. METHOD: This single-center prospective randomized controlled study evaluated the AI system in assisting non-expert and expert operators. Patients with and without FLLs were enrolled and had ultrasound performed twice, with and without AI assistance. McNemar's test was used to compare paired FLL detection rates and false positives between groups with and without AI assistance. RESULTS: 260 patients with 271 FLLs and 244 patients with 240 FLLs were enrolled into the groups of non-expert and expert operators, respectively. In non-experts, FLL detection rate in the AI assistance group was significantly higher than the no AI assistance group (36.9 % vs 21.4 %, p < 0.001). In experts, FLL detection rates were not significantly different between the groups with and without AI assistance (66.7 % vs 63.3 %, p = 0.32). False positive detection rates in the groups with and without AI assistance were not significantly different in both non-experts (14.2 % vs 9.2 %, p = 0.08) and experts (8.6 % vs 9.0 %, p = 0.85). CONCLUSIONS: The AI system resulted in significant increase in detection of FLLs during ultrasound examinations by non-experts. Our findings may support future use of the AI system in resource-limited settings where ultrasound examinations are performed by non-experts. The study protocol was registered under the Thai Clinical Trial Registry (TCTR20201230003), which is part of the WHO ICTRP Registry Network.

ABSTRACT

INTRODUCTION: Abdominopelvic injuries are common, and bleeding occurring in both cavities requires various bleeding control techniques i.e., laparotomy, angiographic embolization (AE), and orthopedic fixation. Hence, the use of Trauma Hybrid Operating Room (THOR) in abdominopelvic injuries has theoretical advantages including rapid bleeding control and minimizing patient transportation. The objective of the present study is to evaluate the impact of THOR in abdominopelvic injuries. METHOD: A pre-post intervention study of abdominopelvic injury patients requiring both surgery and interventional radiology (IR) procedures for bleeding control from January 2015 to May 2020 was conducted. The patients were divided into 2 groups, pre-THOR group (received surgery in OR and scheduled for IR procedures in a separate IR suite, before December 2017) and THOR group (received all procedures in THOR, after December 2017). The primary outcomes were procedure time (including transit time in the pre-THOR group) and mortality. RESULTS: Ninety-one abdominopelvic trauma patients were identified during the study period, 56 patients in pre-THOR group and 35 patients in THOR group. Distribution of injuries was similar in both groups (59 abdominal injuries, 25 pelvic fractures, and 7 combined injuries). The bleeding-control interventions in both groups were 79 laparotomies, 10 preperitoneal pelvic packings, 12 pelvic fixations, 45 liver AEs, and 21 pelvic AEs. THOR group underwent significantly less thoracotomy (1 vs. 11, p = 0.036), more resuscitative endovascular balloon occlusion of the aorta (REBOA, 0 vs. 5, p = 0.014), and more pelvic AE (13 vs. 9, p = 0.043). The procedure time was significantly shorter in THOR group (153 min vs. 238 min, p = 0.030). Excluding the transit time in the pre-THOR group, procedure time was not significantly different (153 vs. 154 min, p = 0.872). Both groups had similar mortality rates of 34%, but the mortality due to exsanguination was significantly lower in THOR group (11% vs. 34%, p = 0.026). CONCLUSIONS: THOR eliminated transit time, resulting in shorter procedure time in abdominopelvic trauma patients requiring bleeding-control intervention. Although overall mortality reduction could not be demonstrated, the mortality due to exsanguination was reduced in THOR group.

ABSTRACT

Novel biomarkers are highly required for the diagnosis and predicting prognosis of hepatocellular carcinoma (HCC). In this study, we investigated the profiles of long non-coding RNAs (lncRNAs) obtained from the peripheral blood mononuclear cells (PBMCs) of patients with HCC and PBMCs from a co-culture model using transcriptomic analysis. The differentially expressed lncRNAs (DElncRNAs) were then characterized and integrated as cancer-induced lncRNAs. Among them, three up-regulating DElncRNAs including MIR4435-2HG, SNHG9 and lnc-LCP2-1 and one down-regulating, lnc-POLD3-2, were identified. The functional analysis showed that these enriched lncRNAs were mainly associated with carcinogenesis and immune responses. Following further validation in PBMCs samples (100 HBV-related HCC, 100 chronic hepatitis B and 100 healthy controls), MIR4435-2HG, lnc-POLD3-2 and their combination were revealed to be sensitive biomarkers in discriminating HCC from non-HCC (AUROC = 0.78, 0.80, and 0.87, respectively), particularly among individuals with normal serum alpha-fetoprotein levels. Additionally, high circulating SNHG9 expression was shown to be an independent prognostic factor of overall survival in patients with HCC. These results indicate that determining these lncRNAs in PBMCs could serve as novel diagnostic and prognostic biomarkers for HBV-related HCC.

ABSTRACT

OBJECTIVE: Hepatocellular carcinoma (HCC) represents a global health concern, particularly in Southeast Asia where hepatitis B virus (HBV) infection is common. In this study, we applied tissue-based proteomics to identify novel serological proteins for HCC and validated their performance in serum specimens. METHODS: In a discovery set, liver tissue specimens of HBV-related HCC, intrahepatic cholangiocarcinoma (iCCA) and colorectal cancer with liver metastasis (CRLM) were analyzed using mass spectrometry (LTQ-Orbitrap-XL). A subset of proteins that showed highly expressed in HCC were then confirmed by Western blotting. Additionally, clinical significance of selected candidate proteins was tested in serum samples of 80 patients with HBV-related HCC, 50 patients with HBV-related liver cirrhosis and 30 healthy controls. RESULTS: Based on LTQ-Orbitrap-XL mass spectrometer, various differentially expressed proteins (DEPs) between tumor and adjacent non-tumor tissues were identified. These included 77 DEPs for HCC, 77 DEPs for iCCA and 55 DEPs for CRLM. Among selected candidate proteins, annexin A2 and cathepsin D were confirmed to be overexpressed in HCC tissue by Western blot analysis. In a validate cohort, serum cathepsin D level, but not annexin A2, was significantly higher in HCC compared with the non-HCC groups. Serum cathepsin D level was also positively correlated with tumor size and tumor stage. Additionally, the combined assay of serum cathepsin D and alpha-fetoprotein had a high sensitivity in detecting early HCC (83%) and intermediate/advanced HCC (96%). Moreover, patients with low serum cathepsin D (<305 ng/mL) displayed significantly better overall survival than those whose serum levels were high (≥305 ng/mL). CONCLUSIONS: Proteomics and subsequent validation revealed cathepsin D as a novel biomarker for HCC. Apart from its diagnostic role, serum cathepsin D might also serve as a prognostic biomarker of HCC. Additional large-scale studies are needed to verify our findings.

ABSTRACT

BACKGROUND: Heterogeneity of liver function and tumor burden in intermediate-stage hepatocellular carcinoma (HCC) results in different outcomes after transarterial chemoembolization (TACE). Easy albumin-bilirubin (EZ-ALBI), a simplified albumin-bilirubin (ALBI) score, has recently been proposed as a new prognostic score for HCC. This study aimed to validate the EZ-ALBI score and evaluate the impact of dynamic changes in patients with intermediate-stage HCC undergoing TACE. METHODS: All patients with HCC treated with TACE at King Chulalongkorn Memorial Hospital, Bangkok, Thailand, between January 2015 and December 2019 were prospectively enrolled. Intermediate-stage HCC was defined as Barcelona Clinic Liver Cancer (BCLC) stage B or unresectable single HCC with size > 5 cm in BCLC stage A. EZ-ALBI and ALBI scores were calculated and stratified into three different grades. Overall survival (OS) and prognostic factors were assessed using the Kaplan-Meier curve and Cox proportional hazard model. Decision analysis curves were used to evaluate the clinical utility of the predictive scores. RESULTS: Among 672 patients with HCC treated with TACE, 166 patients with intermediate-stage HCC who met the eligibility criteria were enrolled. The median OS of all patients in the cohort was 21 months. A good correlation between the EZ-ALBI and ALBI scores was observed (correlation coefficient 1.000, p < 0.001). The baseline EZ-ALBI grades 1, 2, and 3 were 24.5%, 70%, and 5.5%, respectively. EZ-ALBI grade can stratify patients with significantly different prognoses (p = 0.002). Baseline EZ-ALBI grade 2, 3, and serum alpha-fetoprotein > 20 ng/ml were significantly associated with OS [hazard ratio (HR) 2.20 (95% confidence interval [CI] 1.24-3.88, p = 0.007), 3.26 (95% CI 1.24-8.57, p = 0.016), and 1.77 (95% CI 1.10-2.84, p = 0.018), respectively]. Following TACE, 42 (29.6%) patients had a worsening EZ-ALBI grade. However, the EZ-ALBI grade migration was not significantly correlated with OS. EZ-ALBI and ALBI score provided improved discriminatory ability (Harrell's concordance index 0.599 and 0.602, respectively) and better net benefit compared with Child-Turcotte-Pugh and Model for End-stage Liver Disease scores. CONCLUSIONS: The baseline EZ-ALBI score demonstrated good predictive performance for survival and a strong correlation with conventional ALBI scores. Both the EZ-ALBI and ALBI scores outperformed other prognostic models in patients with intermediate-stage HCC receiving TACE. However, the dynamic change in the EZ-ALBI grade after TACE was not associated with postprocedural survival.

ABSTRACT

Despite the wide availability of ultrasound machines for hepatocellular carcinoma surveillance, an inadequate number of expert radiologists performing ultrasounds in remote areas remains a primary barrier for surveillance. We demonstrated feasibility of artificial intelligence (AI) to aid in the detection of focal liver lesions (FLLs) during ultrasound. An AI system for FLL detection in ultrasound videos was developed. Data in this study were prospectively collected at a university hospital. We applied a two-step training strategy for developing the AI system by using a large collection of ultrasound snapshot images and frames from full-length ultrasound videos. Detection performance of the AI system was evaluated and then compared to detection performance by 25 physicians including 16 non-radiologist physicians and 9 radiologists. Our dataset contained 446 videos (273 videos with 387 FLLs and 173 videos without FLLs) from 334 patients. The videos yielded 172,035 frames with FLLs and 1,427,595 frames without FLLs for training on the AI system. The AI system achieved an overall detection rate of 89.8% (95%CI: 84.5-95.0) which was significantly higher than that achieved by non-radiologist physicians (29.1%, 95%CI: 21.2-37.0, p < 0.001) and radiologists (70.9%, 95%CI: 63.0-78.8, p < 0.001). Median false positive detection rate by the AI system was 0.7% (IQR: 1.3%). AI system operation speed reached 30-34 frames per second, showing real-time feasibility. A further study to demonstrate whether the AI system can assist operators during ultrasound examinations is warranted.

ABSTRACT

Background: Post transarterial chemoembolization (post-TACE) causes side effects that impact patients, which leads to fatigue symptoms and reduced functional status. However, unrelieved fatigue and reduced functional status may cause patients to withdraw from treatment and negatively affect their lives. Unfortunately, the patients post-TACE only receive routine medical care at the hospital but no follow-up and continuity of care back home. Therefore, comprehensive discharge planning for these problems is necessary. Objective: This study examined the effectiveness of the comprehensive discharge planning program on fatigue and functional status of patients with hepatocellular carcinoma undergoing transarterial chemoembolization. Methods: A randomized clinical controlled trial was used. Fifty-two patients who met the study criteria were randomly assigned to an experimental group (n = 26) receiving the comprehensive discharge planning plus routine care and a control group (n = 26) receiving routine care only. The discharge planning program was developed based on the Transitional Care Model. A demographic and health data questionnaire, Fatigue Severity Scale (FSS), and Enforced Social Dependency Scale (ESDS) were used for data collection. Chi-square, Fisher's exact, Wilcoxon signed-rank, and Mann-Whitney U tests were used for data analysis. Results: The mean scores for fatigue at 30 days after treatment between the experimental and control groups were significantly different (p = 0.003). The mean scores for the fatigue symptoms in the experimental and control groups were 1.27 ± 0.58 and 1.77 ± 0.85, respectively. The functional status from Day 7 to Day 14 after transarterial chemoembolization was different (p = 0.020). In addition, the mean scores for functional status between the experimental and control groups were significantly different (p = 0.020). On Day 14, after transarterial chemoembolization, the experimental group had an increased score in functional status from Day 7 over the scores for those in the control group. Conclusion: The comprehensive discharge planning program effectively reduces fatigue symptoms and enhances the functional status in patients with hepatocellular carcinoma undergoing transarterial chemoembolization. Therefore, the comprehensive discharge planning program can be used by nurses and multidisciplinary teams in order to achieve the effectiveness of nursing care for patients.

ABSTRACT

Cell-free DNA (cfDNA) has been used as a non-invasive biomarker for detecting cancer-specific mutations. However, the mutational profile of cfDNA in Thai patients with hepatocellular carcinoma (HCC) has not been investigated. Here, we demonstrated the utility of using whole-exome sequencing (WES) of cfDNA to define the somatic mutation profiles of HCC in Thai patients. The comprehensive profile of cfDNA was determined with WES to identify variants in matched cfDNA and germline DNA from 30 HCC patients in Thailand who underwent nonoperative therapies. The level of cfDNA was higher in HCC patients compared with chronic hepatitis patients (p-value < 0.001). Single nucleotide variants were present in somatic genes in cfDNA, including in ZNF814 (27%), HRNR (20%), ZNF492 (20%), ADAMTS12 (17%), FLG (17%), OBSCN (17%), TP53 (17%), and TTN (17%). These same mutations were matched to HCC mutation data from The Cancer Genome Atlas (TCGA) and a previous Thai HCC study. The co-occurrence of HRNR and TTN mutations in cfDNA was associated with shorter overall survival in HCC patients (hazard ratio = 1.60, p-value = 0.0196). These findings indicate that the mutational profile of cfDNA accurately reflected that of HCC tissue and suggest that cfDNA could serve as a useful biomarker for diagnosis and prognosis in Thai HCC patients. In addition, we demonstrated the use of the pocket-sized sequencer of Oxford Nanopore Technology to detect copy-number variants in HCC tissues that could be applied for onsite clinical detection/monitoring of HCC.

ABSTRACT

Novel and sensitive biomarkers is highly required for early detection and predicting prognosis of hepatocellular carcinoma (HCC). Here, we investigated transcription profiles from peripheral blood mononuclear cells (PBMCs) of 8 patients with HCC and PBMCs from co-culture model with HCC using RNA-Sequencing. These transcription profiles were cross compared with published microarray datasets of PBMCs in HCC to identify differentially expressed genes (DEGs). A total of commonly identified of 24 DEGs among these data were proposed as cancer-induced genes in PBMCs, including 18 upregulated and 6 downregulated DEGs. The KEGG pathway showed that these enriched genes were mainly associated with immune responses. Five up-regulated candidate genes including BHLHE40, AREG, SOCS1, CCL5, and DDIT4 were selected and further validated in PBMCs of 100 patients with HBV-related HCC, 100 patients with chronic HBV infection and 100 healthy controls. Based on ROC analysis, BHLHE40 and DDIT4 displayed better diagnostic performance than alpha-fetoprotein (AFP) in discriminating HCC from controls. Additionally, BHLHE40 and DDIT4 had high sensitivity for detecting AFP-negative and early-stage HCC. BHLHE40 was also emerged as an independent prognostic factor of overall survival of HCC. Together, our study indicated that BHLHE40 in PBMCs could be a promising diagnostic and prognostic biomarker for HBV-related HCC.

ABSTRACT

BACKGROUND: B-cell activating factor (BAFF), an important cytokine for B lymphocyte activation, has been shown to be increased in chronic hepatitis B virus (HBV) infection. OBJECTIVE: This study aimed at evaluating clinical correlation and prognostic role of plasma BAFF and related polymorphisms in patients with HBV-related hepatocellular carcinoma (HCC). METHODS: Plasma BAFF levels were measured from 100 healthy controls and 490 patients with chronic HBV infection (200 with HCC and 290 without HCC). The rs9514828 and rs12583006 polymorphisms were determined by allelic discrimination. RESULTS: The HCC group had significantly higher BAFF levels compared with the non-HCC group and healthy controls. Among the non-HCC group, the HBeAg-positive subgroup had higher BAFF levels compared with the HBeAg-negative subgroup. In the HCC group, high BAFF levels at initial presentation significantly correlated with alpha-fetoprotein levels, Child-Pugh classification, tumor size and BCLC stage. Multivariate analyses showed that elevated BAFF concentration (± 1,100 pg/ml) was a significant and independent prognostic factor of overall survival in patients with HCC (OR = 2.28, 95%CI: 1.07-4.87; P = 0.034). HCC patients with high BAFF levels (± 1,100 pg/ml) had a poorer median survival than those with low levels (P < 0.001, log-rank test). Regarding BAFF polymorphisms, the frequency of rs9514828 CT + TT genotypes was higher distributed in patients with chronic HBV infection compared with healthy controls (58.0% vs. 46.0%, P = 0.029). CONCLUSIONS: Our data demonstrate for the first time that elevated plasma BAFF levels at baseline exhibit clinical correlation in terms of disease severity and overall survival in HCC patients. Thus, plasma BAFF at initial diagnosis could serve as a prognostic marker for HBV-related HCC.

ABSTRACT

BACKGROUND: Circulating microRNAs (miRNAs) have been shown to dysregulate in many cancer types including hepatocellular carcinoma (HCC). The purpose of this study was to examine the potential diagnostic or prognostic roles of circulating miRNAs in patients with hepatitis B virus (HBV)-related HCC. METHODS: Paired cancerous and adjacent non-cancerous liver tissue specimens of patients with HBV-related HCC were used as a discovery set for screening 800 miRNAs by a Nanostring quantitative assay. Differentially expressed miRNAs were then examined by SYBR green quantitative RT-PCR in a validation cohort of serum samples obtained from 70 patients with HBV-related HCC, 70 HBV patients without HCC and 50 healthy controls. RESULTS: The discovery set identified miR-223-3p, miR-199a-5p and miR-451a significantly lower expressed in cancerous tissues compared with non-cancerous tissues. In the validated cohort, circulating miR-223-3p levels were significantly lower in the HCC group compared with the other groups. The combined use of serum alpha-fetoprotein and miR-223-3p displayed high sensitivity for detecting early HCC (85%) and intermediate/advanced stage HCC (100%). Additionally, serum miR-223-3p had a negative correlation with tumor size and BCLC stage. On multivariate analysis, serum miR-223-3p was identified as an independent prognostic factor of overall survival in patients with HCC. In contrast, circulating miRNA-199a-5p and miR-451a did not show any clinical benefit for the diagnosis and prognostic prediction of HCC. CONCLUSIONS: Our results demonstrated that miR-223-3p was differentially expressed in cancerous compared with paired adjacent non-cancerous tissues. In addition, circulating miRNA-223-3p could represent a novel diagnostic and prognostic marker for patients with HBV-related HCC.

ABSTRACT

BACKGROUND: Single nucleotide polymorphisms (SNPs) in the sodium taurocholate co-transporting polypeptide (NTCP) have been showed to be associated with natural history of hepatitis B virus (HBV) infection. However, it is unclear whether the SNPs are related to the clinical outcome of HBV infection in Thai individuals. METHODS: The rs2296651 and rs4646287 polymorphisms of NTCP were determined by allelic discrimination using commercial TaqMan probes in blood samples of 1021 Thai individuals. These subjects included 610 patients with chronic HBV infection [CHB, 305 with hepatocellular carcinoma (HCC) and 305 without HCC], 206 subjects with spontaneous HBV clearance and 205 healthy controls who were age and gender-matched. RESULTS: The frequencies of rs2296651 A minor allele in the CHB group, the HBV clearance group and healthy controls were 7.8, 7.3 and 13.9%, respectively. For rs4646287, the frequencies of T minor allele of the corresponding groups were 10.4, 8.0 and 9.5%, respectively. Compared with healthy controls, the frequencies of rs2296651 GA + AA genotypes were significantly lower in the CHB group (P < 0.001) and in the HBV clearance group (P = 0.001). There was no difference in their distribution between the HBV clearance and CHB groups. Among the CHB group, the distribution of GA + AA genotypes in patients with HCC were significantly lower than in patients without HCC (P = 0.014). The frequencies of HBeAg positivity in patients harboring GG and GA + AA genotypes were 39.8 and 23.5%, respectively (P = 0.004). Among patients with HCC, the mean HBV DNA of the corresponding genotypes were 4.9 ± 1.3 vs. 2.7 ± 1.0 log10 IU/mL, respectively (P < 0.001). There was no difference in genotype and allele frequencies of rs4646287 polymorphism among all studied groups. CONCLUSIONS: Our results showed that rs2296651 polymorphism was associated with a decreased risk of susceptibility to HBV infection and the development of HCC. These data suggest that the NTCP polymorphism might have an influence on natural history of HBV infection in Thai individuals.

ABSTRACT

OBJECTIVES: In the management of patients with bleeding peptic ulcers, recurrent bleeding is associated with high mortality. We investigated if added angiographic embolisation after endoscopic haemostasis to high-risk ulcers could reduce recurrent bleeding. DESIGN: After endoscopic haemostasis to their bleeding gastroduodenal ulcers, we randomised patients with at least one of these criteria (ulcers≥20 mm in size, spurting bleeding, hypotensive shock or haemoglobin<9 g/dL) to receive added angiographic embolisation or standard treatment. Our primary endpoint was recurrent bleeding within 30 days. RESULTS: Between January 2010 and July 2014, 241 patients were randomised (added angiographic embolisation n=118, standard treatment n=123); 22 of 118 patients (18.6%) randomised to angiography did not receive embolisation. In an intention-to-treat analysis, 12 (10.2%) in the embolisation and 14 (11.4%) in the standard treatment group reached the primary endpoint (HR 1.14, 95% CI 0.53 to 2.46; p=0.745). The rate of reinterventions (13 vs 17; p=0.510) and deaths (3 vs 5, p=0.519) were similar. In a per-protocol analysis, 6 of 96 (6.2%) rebled after embolisation compared with 14 of 123 (11.4%) in the standard treatment group (HR 1.89, 95% CI 0.73 to 4.92; p=0.192). None of 96 patients died after embolisation compared with 5 (4.1%) deaths in the standard treatment group (p=0.108). In a posthoc analysis, embolisation reduced recurrent bleeding only in patients with ulcers≥15 mm in size (2 (4.5%) vs 12 (23.1%); p=0.027). CONCLUSIONS: After endoscopic haemostasis, added embolisation does not reduce recurrent bleeding. TRIAL REGISTRATION NUMBER: NCT01142180.

ABSTRACT

BACKGROUND: This study was aimed at evaluating the association between single nucleotide polymorphisms (SNPs) in the PNPLA3, NCAN, TM6SF2 and MBOAT7 and hepatocellular carcinoma (HCC) development in Thai patients according to underlying etiologies of liver disease. METHODS: These SNPs were determined by allelic discrimination in blood samples of 105 healthy controls and 530 patients with HCC [270 with hepatitis B virus (HBV-HCC), 131 with hepatitis C virus (HCV-HCC), and 129 with non-B, non-C HCC (NBNC-HCC) matched for age and gender]. RESULTS: G allele of PNPLA3 rs738409 variant was significantly higher in NBNC-HCC (49%) compared to healthy controls (32%), HBV-HCC (32%) and HCV-HCC (31%) (P < 0.001). T allele of TM6SF2 rs58542926 was more prevalent in NBNC-HCC (24%) than in healthy controls (8%), HBV-HCC (10%) and HCV-HCC (12%) (P < 0.001). The distribution of NCAN (rs2228603) and MBOAT7 (rs641738) was not different between groups. In multivariate logistic regression analysis, PNPLA3 rs738409 (OR 2.06, 95% CI 1.24-3.43; P = 0.005) and TM6SF2 rs58542926 (OR 2.22, 95% CI 1.34-3.65; P = 0.002) were independently associated with NBNC-HCC compared to viral-related HCC (VR-HCC). The proportion of patients with NBNC-HCC increased significantly along with the increase of the number of risk alleles. There was no association between these SNPs and overall survival in patients with HCC. CONCLUSIONS: These data showed that PNPLA3 and TM6SF2 polymorphisms were independently linked to NBNC-HCC but not HBV- or HCV-HCC in Thai populations. In addition, the risk genotypes might interact with each other through tumor development in patients with NBNC-HCC.

ABSTRACT

AIM: Serum glycosylated Wisteria floribunda agglutinin-positive Mac-2 binding protein (WFA+ -M2BP) is a novel marker for staging liver fibrosis and predicting hepatocellular carcinoma (HCC) occurrence. This study aimed at evaluating the performance of WFA+ -M2BP in the diagnosis of HCC in patients with chronic hepatitis B virus (HBV) infection. METHODS: The WFA+ -M2BP levels were measured in stored samples collected at initial diagnosis of 150 patients with HBV-related HCC and 150 age- and gender-matched patients with non-malignant chronic HBV infection. RESULTS: Patients with HCC had higher levels of WFA+ -M2BP than those without HCC (3.9 [1.5-20.6] vs. 1.6 [0.4-9.3] cut-off index [COI], P < 0.001). In the HCC group, WFA+ -M2BP levels correlated with Child-Pugh classification but did not correlate with HBV markers, α-fetoprotein (AFP), or Barcelona Clinic Liver Cancer (BCLC) stage. The areas under the curve (AUROC) for differentiating HCC from non-HCC were 0.92 (95% confidence interval [CI], 0.89-0.95; P < 0.001) for WFA+ -M2BP, 0.90 (95% CI, 0.87-0.94; P < 0.001) for AFP, and 0.97 (95% CI, 0.95-0.98; P < 0.001) for the combination of both markers. At the optimal cut-off (2.4 COI), WFA+ -M2BP had sensitivity, specificity, and accuracy of 79.3%, 91.3%, and 85.3%, respectively. The WFA+ -M2BP marker was superior to AFP in differentiating early-stage HCC (BCLC stages 0 and A) from cirrhosis with AUROC of 0.80 (95% CI, 0.68-0.91; P < 0.001) and 0.73 (95% CI, 0.60-0.86; P = 0.002), respectively. By univariate analysis, elevated WFA+ -M2BP (≥4.0 COI) was correlated with poor overall survival in patients with HCC. CONCLUSIONS: Wisteria floribunda agglutinin-positive M2BP showed a better diagnostic performance than AFP in detecting early-stage HCC. Thus, WFA+ -M2BP level could represent a promising marker for early diagnosis of HCC in patients with chronic HBV infection.

ABSTRACT

Hepatocellular carcinoma (HCC) is major health problem with high mortality rates, especially in patients with hepatitis B virus (HBV) infection. Telomerase function is one of common mechanisms affecting genome stability and cancer development. Recent studies demonstrated that genetic polymorphisms of telomerase associated genes such as telomerase associated protein 1 (TEP1) rs1713449 and PIN2/TERF1-interacting telomerase inhibitor 1 (PINX1) rs1469557 may be associated with risk of HCC and other cancers. In this study, 325 patients with HCC and 539 non-HCC groups [193 healthy controls, 80 patients with HBV-related liver cirrhosis (LC) and 266 patients with HBV-related chronic hepatitis (CH)] were enrolled to explore genetic polymorphisms of both SNPs using the allelic discrimination method based on MGB probe TaqMan real time PCR. We demonstrated that all genotypes of both genes were in Hardy-Wienberg equilibrium (>0.05). Moreover, there was no significant association between rs1713449 genotypes and HCC risk, HCC progression and overall survival (>0.05). Interestingly, we observed positive association of rs1469557 with risk of HCC when compared with the LC group under dominant (CC versus CT+TT, OR=1.89, 95% CI= 1.06-3.40, P=0.031) and allelic (C versus T alleles, OR=1.75, 95% CI=1.04-2.94, P=0.033) models, respectively. Moreover, overall survival of HCC patients with CC genotype of rs1469557 was significantly higher than non-CC genotype (Log-rank P=0.015). These findings suggest that PINX1 rs1469557 but not TEP1 rs1469557 might play a role in HCC progression in Thai patients with LC and be used as the prognosis marker to predict overall survival in HCC patients.

ABSTRACT

BACKGROUND: The aims of this study were to evaluate the diagnostic and prognostic roles of serum osteopontin (OPN) and single nucleotide polymorphisms (SNPs) in the OPN promoter in patients with hepatitis B-related hepatocellular carcinoma (HCC). MATERIALS AND METHODS: Four groups were studied, which included 157 patients with HCC, 73 with liver cirrhosis (LC) and 97 with chronic hepatitis (CH), along with 80 healthy subjects. Serum OPN and alpha-fetoprotein (AFP) levels were measured. The SNPs -66 T/G, -156 G/δG and -433 C/T within the OPN promoter were determined by direct sequencing. RESULTS: Serum OPN levels were significantly higher in patients with HCC than in the other groups. Area under receiver operating characteristics curves in distinguishing HCC from chronic liver disease (CLD; CH and LC) were 0.782 (95% CI; 0.729-0.834) for OPN and 0.888 (95% CI; 0.850-0.927) for AFP. Using the optimal cut-off value (70 ng/mL), OPN had sensitivity and specificity of 72% and 71%, respectively. Serum OPN was superior to AFP in detecting early-stage HCC (68% vs. 46%). A combination of both markers yielded an improved sensitivity for detecting early HCC to 82%. A high OPN level was significantly correlated with advanced BCLC stage and was an independent prognostic factor for HCC. The SNPs -156 and -443 were associated with susceptibility to HCC, but were not related to overall survival. CONCLUSIONS: Serum OPN is a useful diagnostic and prognostic marker for HCC. The combined use of serum OPN and AFP improved the diagnosis of early HCC. Genetic variation in the OPN promoter is associated with the risk, but not the prognosis of HCC.

ABSTRACT

The single nucleotide polymorphism (SNP) rs1053004 in Signal transducer and activator of transcription 3 (STAT3) was recently reported to be associated with chronic hepatitis B (CHB)-related hepatocellular carcinoma (HCC) in a Chinese cohort. This study was aimed at investigating whether the SNP might also contribute to HCC susceptibility in the Thai population. Study subjects were enrolled and divided into 3 groups including CHB-related HCC (n=211), CHB without HCC (n=233) and healthy controls (n=206). The SNP was genotyped using allelic discrimination assays based on TaqMan real-time PCR. Data analysis revealed that the distribution of different genotypes was in Hardy-Weinberg equilibrium (P>0.05). The frequencies of allele T (major allele) in HCC patients, CHB patients and healthy controls were 51.4%, 58.6% and 61.4%, respectively, whereas the frequencies of C allele (minor allele) were 48.6%, 41.4% and 38.6%. The C allele frequency was higher in HCC when compared with CHB patients (odds ratio (OR)=1.34, 95% confidence interval (CI)=1.02-1.74, P=0.032). The genotype of SNP rs1053004 (CC versus TT+TC) was significantly associated with an increased risk when compared with CHB patients (OR=1.83, 95% CI=1.13-2.99, P=0.015). In addition, we observed a similar trend of association when comparing HCC patients with healthy controls (OR=1.77, 95% CI=1.07-2.93, P=0.025) and all controls (OR=1.81, 95% CI=1.19-2.74, P=0.005). These findings suggest that the SNP rs1053004 in STAT3 might contribute to HCC susceptibility and could be used as a genetic marker for HCC in the Thai population.
