Evaluation of the Clinical Utility of Detecting Circulating Tumor DNA (ctDNA) Mutation Gene Locus TP53 rs28934571 (c.747G>T) Using Real Time PCR (RT-PCR) and Droplet Digital PCR (ddPCR) in Egyptian Hepatocellular Carcinoma Patients

Abstract Background the detection and analysis of circulating nucleic acids in blood may aid not only in disease diagnosis but also in guiding molecular targeted therapy, monitoring response to such or other treatments, as well as identifying mutations associated with drug resistance. Furthermore, unlike a tumor biopsy, circulating nucleic acids may provide useful information regarding tumor heterogeneity. Objective compare ctDNA by targeting the hotspot mutation gene locus TP53 rs28934571 (c.747G>T) in normal persons, chronic liver disease patients, early and late HCC cases to evaluate its diagnostic value and analyse ctDNA Patients and Methods It was performed on 100 adult subjects. Patients were recruited from October 2020 through June 2022 from Ain Shams Centre for Organ Transplantation and Tropical Medicine Department, Ain Shams University Hospitals, including: Eighty (80) patients diagnosed with HCC on top of HCV according to European Association for Study of the Liver (EASL) guidelines. In addition, a non-HCC group was included: ten (10) HCV-positive patients and ten (10) healthy controls were recruited to the study (non-HCC group). HCC clinical stage was determined according to Barcelona Clinic Liver Cancer (BCLC) staging classification and Child-Pugh classification Results There was no significant statistical difference between the HCC group, healthy control and HCV control group as regards age (p value = .09), sex (p value = 1) and comorbidities. AST was found statistically significant in HCC group in comparison with healthy control group (p value = .018) and there was statistical significant difference between HCC group and (healthy and HCV) control groups as regards albumin(p value = .03) and INR (p value <.001). 40 patients (50 %) were within Milan criteria, 12 patients (15%) were within USCF, 28 patients (35%)were beyond all and 39 patients (48.75%) were child A. Mean meld score was 12.45 ± 5.94. As regards the tumor charecterictics in the explant pathology of HCC patients

Functional liver imaging score (FLIS) can predict adverse events in HCC patients

PurposeTo assess the performance of FLIS in predicting adverse outcomes, namely post-hepatectomy liver failure (PHLF) and death, in patients who underwent liver surgery for malignancies. MethodsAll consecutive patients who underwent liver resection and 1.5 T gadoxetic acid MR were enrolled. PHLF and overall survival (OS) were collected. Two radiologists with 18 and 8 years of experience in abdominal imaging, blinded to clinical data, evaluated all images. Radiologists evaluated liver parenchymal enhancement (EnQS), biliary contrast excretion (ExQS), and signal intensity of the portal vein relative to the liver parenchyma (PVsQs). Reliability analysis was computed with Cohen’s Kappa. Cox regression analysis was calculated to determine which factors are associated with PHLF and OS. Area Under the Receiver Operating Characteristic curve (AUROC) was computed. Results150 patients were enrolled, 58 (38.7 %) in the HCC group and 92 (61.3 %) in the non-HCC group. The reliability analysis between the two readers was almost perfect (κ = 0.998). The multivariate Cox analysis showed that only post-surgical blood transfusions and major resection were associated with adverse events [HR=8.96 (7.98–9.88), p = 0.034, and HR=0.99 (0.781–1.121), p = 0.032, respectively] in the whole population. In the HCC group, the multivariable Cox analysis showed that blood transfusions, major resection and FLIS were associated with adverse outcomes [HR=13.133 (2.988–55.142), p = 0.009, HR=0.987 (0.244–1.987), p = 0.021, and HR=1.891 (1.772–3.471), p = 0.039]. The FLIS AUROC to predict adverse outcomes was 0.660 (95 %CIs = 0.484–0.836), with 87 % sensitivity and 33.3 % specificity (81.1–94.4 and 22.1–42.1). ConclusionsFLIS can be considered a promising tool to preoperative depict patients at risk of PHLF and death.

Clinical Utility of CTNNB1 (c.121A>G) Mutation in Circulating Tumor DNA in Egyptian Patients with Hepatocellular Carcinoma: A Case-Control Study

Abstract Background Hepatocellular carcinoma (HCC) is the most common malignancy of the liver and with 782,000 new cases annually and 600,000 deaths/year globally. In Egypt, HCC causes a significant public health problem with a rising incidence as it is strongly linked to viral hepatitis mainly HCV. CTNNB1 mutations is one of the most common genetic alterations in HCC. Our aim is to investigate the clinical utility of CTNNB1 (rs121913412) single nucleotide variation (SNV) in ctDNA in patients with early and late-stage HCC in comparison to chronic HCV patients and healthy controls. Methods All participants were subjected to history taking, clinical evaluation, laboratory investigations including liver profile, kidney function tests, alfa-fetoprotein. Additionally, complete blood counts and coagulation profile were done. Child and Model for End-Stage Liver Disease (MELD) scores were calculated, BCLC staging was done for each patient and radiological protocol for HCC (spiral triphasic CT or MRI). Genotyping of rs121913412 CTNNB1 (c.121A>G) on extracted DNA from blood samples was done using Real Time PCR System. Results Thirty patients with HCC on top of HCV were recruited including 14 early HCC and 16 with advanced HCC in addition to non-HCC group including 10 HCV-positive patients and 10 healthy controls. All participants have undergone laboratory investigations and radiological protocol for HCC cases. Genotyping of rs121913412 CTNNB1 (c.121A>G) in peripheral blood samples using RT-PCR for all cases was done. The genotype AA was detected in 27out of 30 (30%) of the cases while 3 HCC cases out of 30 (10 %) were positive for the CTNNB1 p.T41A mutation; AG phenotype (heterozygous), no cases showed GG phenotype. In HCV- positive patients’ group and healthy controls none were positive for the CTNNB1 mutation all showed wild AA genotype. No significant differences in the genotype (AA, AG, GG) distribution between HCC and non-HCC groups (χ2=3.619, p = 0.0571). The frequency of AA vs AG + GG genotype was considerably higher in cases when compared to controls however no statistical significance was detected (χ2=3.619, p = 0.0571). Distribution of A vs G allele in cases compared to controls showed statistically significant difference (χ2=4.571, p = 0.0325). Conclusion In this study we were not able to prove the clinical utility of CTNNB1 rs121913412 in Egyptian HCC patients. Further large multi-centric studies are needed to explore the clinical utility of ctDNA in assessment of tumor-specific hotspot somatic mutations in genes including CTNNB1, TERT and TP53 genes that can be identified in the peripheral blood of HCC patients. Comparison studies utilizing both ctDNA and DNA extracted from HCC tissue samples are recommended.

MiRNA Expression and HCC Occurrence in HCV Cirrhotic Patients Treated with Direct Acting Antivirals

Background: The risk of hepatocarcinoma in HCV cirrhotic patient responders after treatment with DAAs decrease, but HCC still occurs. A correlation between specific miRNAs and the development of hepatocarcinoma have been highlighted. Aim: To investigate miRNA expression in HCV-infected cirrhotic patients treated with DAAs, regarding whether or not they developed HCC at follow-up. Methods: A total of 73 outpatients with HCV-related cirrhosis treated with DAAs were enrolled, 28 of which had HCC. Samples were collected at the start and at the end of treatment. In the screening phase, 172 miRNAs were analyzed at baseline. Differentially expressed miRNAs were validated in the entire cohort. Results: In the validation phase, at baseline and in patients treated for 12 weeks, miR-28-5p was confirmed to be more highly expressed in the HCC group compared to the non-HCC group. In all of the patients treated for 12 weeks, at end of the treatment we found a significant downregulation in miR-132-3p, miR-133b-3p, miR-221-3p and miR-324-3p. In the HCC group, miR-28-5p was significantly downregulated after DAA therapy as well as in HCC patients treated for 24 weeks. Conclusion: In the HCC group, miR28-5p was differently expressed both at baseline and at the end of therapy with DAAs. This difference in expression should suggest its involvement in HCC development.

Evaluation of the risk of developing hepatocellular carcinoma in chronic Hepatitis C patients receiving antiviral treatment.

Chronic HC leads to the development of liver cirrhosis (LC) and hepatocellular carcinoma (HCC). The treatment of chronic HC with DAAs reduces mortality from LC and HCC.The study aimed to investigate the serological markers specific to HCC (PIVKA-II and AFP) in patients with chronic HC before and after DAA treatment. The study involved 35 HCV patients (mean age: 56.23 ± 1.45) divided into two groups. Group 1 included 15 HCV + HCC patients and Group 2 included 20 HCV non-HCC patients. At the end of treatment all the patients were HCV RNA negative. Three months after the end of antiviral treatment, HCV RNA was undetectable in all patients, while a complete biochemical and virological response was observed in 66.7% of HCV + HCC patients and 85.0% of HCV non-HCC patients. PIVKA-II levels before the initiation of antiviral treatment were high in all patients. At the end of the treatment, in the HCV non-HCC group, normalization of PIVKA-II levels was observed only in 20.0% cases, and in 60.0% of cases 3 months after the treatment. Meanwhile, in patients with HCC and chronic HCV, PIVKA-II levels were within the normal range 3 months after treatment in only 13.3% of patients. It is necessary to monitor HCV patients with cirrhosis (F4) and severe fibrosis (F3) without HCC, who have high PIVKA-II and AFP levels and/or ALT activity despite obtaining sustained virologic response 3 months after treatment with DAAs.

Diagnostic value of serum STIP1 in HCC and AFP-negative HCC.

This study aimed to investigate the diagnostic value of stress-induced phosphoprotein 1 (STIP1) in serum for hepatocellular carcinoma (HCC) and alpha-fetoprotein (AFP)-negative HCC (ANHC). In this study, serum samples were collected from 158 HCC patients and 63 non-HCC patients. Logistic regression analysis was performed to identify independent risk factors associated with HCC and ANHC. The diagnostic values of each index for HCC and ANHC were analyzed using receiver operating characteristic (ROC) curve analysis. The STIP1, des-γ-carboxy prothrombin (DCP), and AFP levels were higher in the HCC groups than in the non-HCC groups (P < .05). Age, DCP, STIP1, and hepatitis B virus infection were independent predictors of HCC (P < .05). The diagnostic value of STIP1 for HCC was higher than that of DCP. Additionally, age, STIP1, and hepatitis B virus infection were independent predictors for ANHC patients. The ROC curve exhibited an area under the curve value of 0.919 for STIP1, with a diagnostic cutoff value of 68.5 U/mL. Moreover, 36 ANHC patients and 19 AFP-negative non-HCC patients were included to validate the diagnostic model. A total of 20 patients had STIP1 levels greater than 68.5 U/mL, resulting in diagnostic accuracy of 67.3%, sensitivity of 55.6%, and specificity of 89.5%. STIP1 demonstrates excellent diagnostic value for HCC and ANHC.

Dynamic Contrast-Enhanced Ultrasonography Combined With LR-M Classification Criteria for Differentiating Malignant Liver Nodules at High Risk for Hepatocellular Carcinoma

ObjectiveWe aimed to investigate the value of quantitative parameters derived from dynamic contrast-enhanced ultrasonography (DCE-US) and a combination of these quantitative parameters with the LR-M classification criteria in distinguishing hepatocellular carcinoma (HCC) nodules and non-HCC malignancies. MethodsHCC and non-HCC malignant nodules were grouped using pathologic results, and each nodule was classified using CEUS LI-RADS 2017. Quantitative CEUS analysis of each nodule was performed using VueBox, and quantitative parameters were compared between the HCC and non-HCC groups. The diagnostic efficacy of the LR-5 category for HCC was analyzed using the LR-M classification criteria along with time-related quantitative parameters. ResultsOf the 190 malignant liver nodules, 137 and 53 were HCCs and non-HCC malignancies, respectively. The median values of quantitative parameters RT (rise time), TTP (time to peak), mTTl (mean transit time local), and FT (fall time) in the non-HCC malignant group were lower than those in the HCC group, with p < 0.05. There was a statistically significant difference in WiAUC (wash-in area under the curve), WoAUC (wash-out area under the curve), WiWoAUC (wash-in and wash-out area under the curve), and WoR (wash-out rate) values between HCC and non-HCC malignant groups, with p < 0.05. Using LR-M washout time <60 s and FT ≤21.2 s as the new diagnostic standard, the LR-5 category showed a sensitivity of 83.9%, specificity of 96.2%, and positive predictive value of 98.3% for HCC diagnosis. ConclusionDCE-US can facilitate the distinction of HCCs and non-HCC malignancies. Non-HCC malignancies present with earlier peak enhancement and more rapid and marked washout than HCC nodules. The combination of the LR-M classification criteria and FT ≤21.2 s can significantly improve the diagnostic sensitivity of the LR-5 category for HCC.

Optimizing LI-RADS: ancillary features screened from LR-3/4 categories can improve the diagnosis of HCC on MRI

ObjectiveTo determine the high-efficiency ancillary features (AFs) screened from LR-3/4 lesions and the HCC/non-HCC group and the diagnostic performance of LR3/4 observations.Materials and methodsWe retrospectively analyzed a total of 460 patients (with 473 nodules) classified into LR-3-LR-5 categories, including 311 cases of hepatocellular carcinoma (HCC), 6 cases of non-HCC malignant tumors, and 156 cases of benign lesions. Two faculty abdominal radiologists with experience in hepatic imaging reviewed and recorded the major features (MFs) and AFs of the Liver Imaging Reporting and Data System (LI-RADS). The frequency of the features and diagnostic performance were calculated with a logistic regression model. After applying the above AFs to LR-3/LR-4 observations, the sensitivity and specificity for HCC were compared.ResultsThe average age of all patients was 54.24 ± 11.32 years, and the biochemical indicators ALT (P = 0.044), TBIL (P = 0.000), PLT (P = 0.004), AFP (P = 0.000) and Child‒Pugh class were significantly higher in the HCC group. MFs, mild-moderate T2 hyperintensity, restricted diffusion and AFs favoring HCC in addition to nodule-in-nodule appearance were common in the HCC group and LR-5 category. AFs screened from the HCC/non-HCC group (AF-HCC) were mild–moderate T2 hyperintensity, restricted diffusion, TP hypointensity, marked T2 hyperintensity and HBP isointensity (P = 0.005, < 0.001, = 0. 032, p < 0.001, = 0.013), and the AFs screened from LR-3/4 lesions (AF-LR) were restricted diffusion, mosaic architecture, fat in mass, marked T2 hyperintensity and HBP isointensity (P < 0.001, = 0.020, = 0.036, < 0.001, = 0.016), which were not exactly the same. After applying AF-HCC and AF-LR to LR-3 and LR-4 observations in HCC group and Non-HCC group, After the above grades changed, the diagnostic sensitivity for HCC were 84.96% using AF-HCC and 85.71% using AF-LR, the specificity were 89.26% using AF-HCC and 90.60% using AF-LR, which made a significant difference (P = 0.000). And the kappa value for the two methods of AF-HCC and AF–LR were 0.695, reaching a substantial agreement.ConclusionWhen adjusting for LR-3/LR-4 lesions, the screened AFs with high diagnostic ability can be used to optimize LI-RADS v2018; among them, AF-LR is recommended for better diagnostic capabilities.

Triglyceride-Glucose Index is an Independent Risk Factor for Hepatocellular Carcinoma Development in Patients with HBV-Related Liver Cirrhosis.

This study aimed to explore the effects of the triglyceride-glucose (TyG) index on hepatocellular carcinoma (HCC) development in patients with hepatitis B virus (HBV)-related liver cirrhosis (LC). A total of 242 patients with HBV-related LC were enrolled and followed-up. Logistic regression analysis was performed to investigate risk factors for HCC. The median follow-up time was 37 months (range: 6-123 months). At the end of the follow-up, 11 (11.3%) patients with compensated cirrhosis (CC) and 45 (31.0%) with decompensated cirrhosis (DC) developed HCC. The TyG index was higher in the HCC group than in the non-HCC group (P=0.05). Univariate analysis showed that age (P<0.01), DC (P<0.01), TyG index (P=0.08), albumin (ALB) level (P=0.05), platelet (PLT) count (P<0.01), and HBV DNA positivity (P<0.01) were associated with HCC development. Multivariate analysis revealed that age, DC, TyG index, PLT count, and HBV DNA positivity were independent risk factors for HCC development (P=0.01, 0.01, <0.01, 0.05, and <0.01, respectively). For patients with DC, multivariate logistic regression analysis revealed that age, TyG index, and HBV DNA positivity were independent risk factors for HCC development (all P<0.05). A new model encompassing age, DC, TyG, PLT, and positive HBV DNA had optimal predictive accuracy in patients with DC or CC, with a cutoff value of 0.197. The areas under the receiver operating characteristic curves (AUROCs) of the model for predicting HCC development in patients with LC, DC, and CC were 0.778, 0.721, and 0.783, respectively. TyG index was identified as an independent risk factor for HCC development in patients with LC.

A model incorporating clinicopathologic and liver imaging reporting and data system-based magnetic resonance imaging features to identify hepatocellular carcinoma in LR-M observations.

To evaluate the predictive value of a combination model of Liver Imaging Reporting and Data System (LI-RADS)-based magnetic resonance imaging (MRI) and clinicopathologic features to identify atypical hepatocellular carcinoma (HCC) in LI-RADS category M (LR-M) observations. A total of 105 patients with HCC based on surgery or biopsy who underwent preoperative MRI were retrospectively reviewed in the training group from hospital-1 between December 2016 and November 2020. The LI-RADS-based MRI features and clinicopathologic data were compared between LR-M HCC and non-HCC groups. Univariate and least absolute shrinkage and selection operator regression analyses were used to select the features. Binary logistic regression analysis was then conducted to estimate potential predictors of atypical HCC. A predictive nomogram was established based on the combination of MRI and clinicopathologic features and further validated using an independent external set of data from hospital-2. Of 113 observations from 105 patients (mean age, 61 years; 77 men) in the training set, 47 (41.59%) were classified as LR-M HCC. Following multivariate analysis, aspartate aminotransferase >40 U/L [odds ratio (OR): 4.65], alpha-fetoprotein >20 ng/mL (OR: 13.04), surface retraction (OR: 0.16), enhancing capsule (OR: 5.24), blood products in mass (OR: 8.2), and iso/hypoenhancement on delayed phase (OR: 10.26) were found to be independently correlated with LR-M HCC. The corresponding area under the curve for a combined model-based nomogram was 0.95 in the training patients (n = 113) and 0.90 in the validation cohort (n = 53). The combined model incorporating clinicopathologic and MRI features demonstrated a satisfactory prediction result for LR-M HCC.

Serial increase and high alpha-fetoprotein levels predict the development of hepatocellular carcinoma in 6months.

Alpha-fetoprotein (AFP) checkup with abdominal ultrasonography for hepatocellular carcinoma (HCC) surveillance remains controversial. We evaluated a serial AFP-increase and high AFP levels in the prediction of HCC. At-risk patients with chronic liver disease underwent HCC surveillance with trimonthly AFP measurement were included and categorized into HCC and non-HCC groups. Their AFP levels at 12, 9, and 6months (-6M) before the outcome date were evaluated. Group-based trajectory analysis and multivariable regression analysis were performed to identify AFP trajectories as risk predictors for HCC. Overall, 2776 patients were included in the HCC (n=326) and non-HCC (n=2450) groups. Serial AFP levels were significantly higher in the HCC than the non-HCC groups. Trajectory analysis identified AFP-increase group (11%) increased 24-fold risks of HCC compared with the AFP-stable (89%) group. Compared with patients without the AFP-increase, a serial 3-month AFP-increase ≥10% elevated HCC risk by 12.1-fold (95% CI: 6.5-22.4) in 6months, and the HCC risks increased 13-60 fold in patients with cirrhosis, hepatitis B, or C receiving antiviral therapy, or AFP levels <20ng/ml. Combining serial AFP-increase ≥10% and AFP ≥20ng/ml at -6M significantly increased 41.7-fold (95% CI: 13.8-126.2) HCC risks. In patients who underwent biannual AFP checkups, those with both 6-month AFP-increase ≥10% and AFP ≥20ng/ml increased 22.1-fold (95% CI: 12.52-39.16) HCC risks in 6months. Most HCCs were detected at an early stage. Serial 3-6-month AFP-increase of ≥10% previously and AFP level of ≥20ng/ml significantly increased HCC risks in 6months.

Liver directed therapies in primary and metastatic liver cancer: A rural academic institution experience.

e16188 Background: Liver-directed therapies (LDT) are well established in the treatment of primary and secondary hepatic malignancies and are developed for potentially curative intent, bridging for definitive therapy or palliation. They are used either in isolation usually for hepatocellular carcinoma (HCC) or in combination with systemic chemotherapy and/or surgery. We conducted a retrospective study at our academic institution that serves ethnic minorities and patients with high BMI and multiple major co-morbidities. Methods: All patients who underwent liver-directed therapy at ECU Health Medical Center from the year 2010 to 2020 were included in this study. Total of 196 patients were identified of which 96 met the eligibility criteria. That criteria included all patients who have undergone any type of liver directed therapy in primary and mainly metastatic gastrointestinal liver cancer. We conducted descriptive univariate analysis, cox regression and Kaplan-Meier survival analysis. Results: The study cohort had 63% (n=60) with primary HCC and 38% (n=36) with metastatic liver cancer predominantly colorectal cancer. Median age at diagnosis was 68 yrs. (65.3-69.5), 58% were Caucasian, 38% were black and 2% were other ethnic groups. 68% of the patient were male and 31% were female. ECOG performance status of 1 in 60% of the cohort. 50% of the cohort had 3 major comorbidities other than cirrhosis and hepatitis. Mean body mass index (BMI) was &gt;25 kg/m2. 43% of the patient (n=41) had multiple barriers to care. Patients with primary HCC, 45% had hepatitis C and 48 % had non-viral causes in 60 patients. Child- Pugh A in 67% (n=40), B in 30% (18) and C in 3% (n=3). 70% of non-HCC cohort has colorectal and cholangiocarcinoma. All patient in non-HCC group received chemotherapy and 52% of HCC cohort received systemic therapy. 55% (n= 43) of the patients underwent Y-90 and 55% (n= 53) underwent other types of liver directed therapies, most common being TACE. 62% of the patient underwent 1 treatment and 38% had &gt;2 LDT. Multivariate analysis showed that age (p-value, 0.0229) and type of liver directed therapy ( p-value, 0.0212) are statistically significant in the HCC cohort. In the non-HCC cohort, patients with high BMI (P-value=0.0050) had poor outcome and was statistically significant. Conclusions: Liver directed therapy is a reasonable option for patients with HCC and non-HCC metastatic disease. According to our study, it improves median survival in non-HCC patients. It includes rural population with high BMI, major comorbidities and multiple barriers to care. In this study, 38% of patients were African Americans who are usually underrepresented in majority of studies. Limitations of the study include retrospective nature of the analysis and heterogenous group. In future clinical trials, ethnic minorities should be equally represented to advance health equity and to apply real word data to the populations we serve.

Research and exploration of salivary biological markers for hepatitis B-related hepatocellular carcinoma

Objective: To study using isotope-labeled relative and absolute quantitative proteomics methodologies to screen for salivary biological markers as a simple, non-invasive tool for identifying hepatitis B-related HCC at an early stage. Methods: Saliva samples were collected to extract salivary proteins. Isotope-labeled relative and absolute quantitative proteomics were used to analyze the differentially expressed proteins between the hepatocellular carcinoma (HCC) and non-HCC groups. Western blotting, immunohistochemistry, and enzyme-linked immunosorbent assays were used to verify differential proteins and identify markers in liver cancer tissues and saliva. Statistical analysis was used to analyze the diagnostic efficiency of salivary biomarkers. Results: 152 differentially expressed salivary proteins were screened out between the HCC and non-HCC groups. Western blot, immunohistochemistry, and enzyme-linked immunosorbent assays validated that the expressions of α-1-acid glycoprotein 1 (ORM1) and alpha-fetoprotein (AFP) were significantly increased in HCC (P < 0.05). There was a significant correlation between salivary AFP and serum AFP (P < 0.05). HCC was diagnosed when salivary α-1-acid glycoprotein 1 combined with AFP. The area under the receiver operating characteristic curve was 0.8726 (95% confidence interval: 0.8104 ~ 0.9347), the sensitivity was 78.3%, and the specificity was 88%. Conclusion: Salivary AFP and α-1-acid glycoprotein 1 can serve as potential biomarkers for hepatitis B-related hepatocellular carcinoma.

Evaluation of Bone Mineral Metabolism After Liver Transplantation by Bone Mineral Densitometry and Biochemical Markers

AimThis study aimed to evaluate the course of bone and mineral metabolism after liver transplantation (LT) in patients with chronic liver disease. MethodsOne hundred four patients who had undergone LT and had a minimum of 6 months of follow-up after LT were included in this prospective cohort study. The following parameters were evaluated for each patient: preoperative and postoperative (postoperative day [POD]30, POD90, POD180) osteocalcin, bone-specific alkaline phosphatase (BALP), type 1 collagen, beta-C-terminal end telopeptide (β-CTx), vitamin D, parathyroid hormone (PTH), ALP, calcium, phosphate, sedimentation, and bone mineral densitometer scores (L2, L4, L total, and F total). The parameters were compared in terms of sex, presence of liver tumor (hepatocellular carcinoma [HCC; n = 19] vs non-HCC [n = 85]), and presence of autoimmune liver disease (autoimmune liver disease [ALD; n = 8] vs non-ALD [n = 96]). ResultsThe median age of the patients (n = 81 men and n = 23 women) was 52 years (95% CI, 50-56). There was a significant change in the defined time intervals in parameters such as osteocalcin (P < .001), BALP (P < .001), β-CTx (P < .001), vitamin D (P < .001), PTH (P < .001), ALP (P = .001), calcium (P < .001), phosphate (P = .001), L2 (P = .038), L total (P = .026), and F total (P < .001) scores. There was a significant difference in POD90 ALP (P = .033), POD180 calcium (P = .011), POD180 phosphate (P = .011), preoperative sedimentation (P = .032), and POD180 F total (P = .013) scores between both sexes. There was a significant difference in POD180 osteocalcin (P = .023), POD180 β-CTx (P = .017), and preOP calcium (P = .003) among the HCC and non-HCC groups. Furthermore, we found significant differences in preoperative ALP (P = .008), preoperative sedimentation (P = .019), POD90 (P = .037) and POD180 L2 (P = .005) scores, preoperative (P = .049) and POD180 L4 (P = .017), and POD180 L total (P = .010) and F total (P = .022) scores between the patients with and without ALD. ConclusionThis study shows that the bone and mineral metabolism of the LT recipients was negatively affected after LT. In addition, we showed that bone and mineral metabolism was more prominent in patients with HCC, and bone mineral density scores were higher in patients with ALD.

Immunosuppressive Medication Adherence in Patients With Hepatocellular Cancer Who Have Undergo Liver Transplantation: A Case Control Study

We aimed to compare the adherence to immunosuppressive medication use in patients who underwent liver transplantation (LT) due to hepatocellular carcinoma (HCC) and non-HCC reasons. The study population was determined as 242 patients with HCC and 1290 patients with non-HCC who had LT performed in our institute between March 2002 and November 2021; all these patients were contacted by phone in March 2022. The sample size was calculated using the MedCalc software program, and the number of patients required in each group was determined as 111 patients. Furthermore, we used the sample.int function, a random integer generator in the R (version 4.1.2) software program. Whereas demographic and clinical parameters were determined as independent variables, the immunosuppressive medication adherence scale (IMAS) score was determined as a dependent variable. Patients were evaluated by the IMAS. This 11-item IMAS scale evaluates the lowest compliance score as 11 and the highest as 55. Out of a total number of 221 patients, 161 (72%) were men and 60 (27.1%) were women, with a median age of 58 years (IQR: 14); one patient in the non-HCC group was excluded due to lack of data. Among the HCC and non-HCC groups, significant differences were found in terms of the variables of age (P=.003), IMAS score (P < .001), sex (P=.001), working status (P=.004), chronic diseases (P=.008), tacrolimus alone (P < .001), tacrolimus plus everolimus (P < .001), and often medication changes (P < .001). A statistically significant correlation was found between the IMAS score and whether the patients had HCC (P < .001) and frequently changing immunosuppressive drugs (P=.023). This study showed that patients with frequent drug changes or non-HCC etiology had better adherence to immunosuppressive drug use.

Effect of the COVID-19 Pandemic on the Psychological Health of Patients Who Underwent Liver Transplantation Due to Hepatocellular Carcinoma

The primary aim of this study was to compare liver transplant (LT) recipients with and without hepatocellular carcinoma (HCC) in terms of COVID-19-related depression, anxiety, and stress. A total of 504 LT recipients with (HCC group; n = 252) and without HCC (non-HCC group; n = 252) were included in the present case-control study. Depression Anxiety Stress Scales (DASS-21) and Coronavirus Anxiety Scale (CAS) were used to evaluate the depression, stress, and anxiety levels of LT patients. DASS-21 total and CAS-SF scores were determined as the primary outcomes of the study. Poisson regression and negative binomial regression models were used to predict the DASS and CAS scores. The incidence rate ratio (IRR) was used as a coefficient. Both groups were also compared in terms of awareness of the COVID-19 vaccine. Poisson regression and negative binomial regression analyses for DASS-21 total and CAS-SF scales showed that the negative binomial regression method was the appropriate model for both scales. According to this model, it was determined that the following independent variables increased the DASS-21 total score: non-HCC (IRR: 1.26; p = 0.031), female gender (IRR: 1.29; p = 0.036), presence of chronic disease (IRR: 1.65; p < 0.001), exposure to COVID-19 (IRR: 1.63; p < 0.001), and nonvaccination (IRR: 1.50; p = 0.002). On the other hand, it was determined that the following independent variables increased the CAS score: female gender (IRR:1.75; p = 0.014) and exposure to COVID-19 (IRR: 1.51; p = 0.048). Significant differences were found between the HCC and non-HCC groups in terms of median DASS-21 total (p < 0.001) and CAS-SF (p = 0.002) scores. Cronbach's alpha internal consistency coefficients of DASS-21 total and CAS-SF scales were calculated to be 0.823 and 0.783, respectively. This study showed that the variables including patients without HCC, female gender, having a chronic disease, being exposed to COVID-19, and not being vaccinated against COVID-19 increased anxiety, depression, and stress. High internal consistency coefficients obtained from both scales indicate that these results are reliable.

The role of PRDM1 gene polymorphism in the progression of hepatocellular carcinoma in Egyptian patients.

In Egypt, hepatocellular carcinoma (HCC) ranks as the second largest cause of cancer mortality. PRDM1 is a tumor suppressor gene essential for the differentiation and regulation activity of plasma cells and T cells. It plays a vital role in T cell exhaustion of chronic viral infection and HCC. We aimed to study the role of PRDM1 gene polymorphism in HCV and HCC-related to hepatitis C virus (HCV) progress in Egyptians. Thecase-control study included 300 Egyptian patients divided into100 HCC,100 cirrhosis, and 100 control. Laboratory investigations were done for some clinicopathological biomarkers, including liver function tests,complete blood picture,serum alpha-fetoprotein, and hepatitis markers (HBsAg, anti-HCV-Ab). TaqMan allelic discrimination assay technique was used to genotype PRDM1 gene polymorphism. Multivariant analysis (logistic regression) assessed the association between the polymorphisms with HCC progression and designed thesuggested model for HCC prediction.The frequencies of the G allele and GG phenotype in the controlgroup were significantly more than that of the HCC and cirrhosis group. However,GA genotypes and A allele frequencies significantly increased in the HCC patients than in cirrhosis and controls. In addition, by comparing the HCC group and the non-HCC group (controls and cirrhotic patients), the subjects carrying AA or GA have 2 times more risk to develop HCC than those carrying GG genotypes (odd ratio = 2.045% and 95%confidence intervalare (1.123-3.722) p = 0.019). Multivariate analysis results suggested a model of Aspartate transaminase (AST), Albumin, and PRDM1 polymorphism to predictthe risk of HCC in Egyptians. In addition, PRDM1 polymorphism has an association with HCC prognosis (tumor size).For PRDM1 polymorphism, the A allele and AA might be considered as HCC-related to theHCV risk factor. In addition, AST, Albumin, and PRDM1 polymorphism predictthe risk of HCC in Egyptians Therefore, the polymorphism might help in identifying the susceptible Egyptians to HCC. In addition, polymorphism might have a role in HCC prognosis.

The combination of serum oligosaccharide chain (G-test), alpha-fetoprotein, and aspartate aminotransferase to alanine aminotransferase ratio provides the optimal diagnostic value for early detection of hepatocellular carcinoma

BackgroundThe purpose of this study was to compare the diagnostic value of serum oligosaccharide chain (G-test), alpha-fetoprotein (AFP) and aspartic aminotransferase to alanine aminotransferase ratios (AAR), both alone and in combination, for predicting hepatocellular carcinoma (HCC) onset.MethodsBetween Januarys 2020–2022, 152 subjects admitted to the First Affiliated Hospital of Nanchang University was enrolled in this study, of which 77 had HCC, 18 chronic hepatitis (CH), 37 liver cirrhosis (LC) and 20 were healthy. Data for patient characteristics were collected, and differences between groups were analyzed by either Mann-Whitney U or χ2 tests. Receiver operating characteristic (ROC) curve analysis was used to determine the diagnostic value of AFP, G-test, and AAR for HCC.ResultsG-test, AFP, and AAR were all found to have close correlations with HCC among the different patient groups, with G-test being the most predictive for HCC among healthy and CL patients, as represented by respective areas under the curve (AUC) of 0.953 and 0.792 (P < 0.001). By contrast, AAR had the greatest diagnostic ability for HCC among CH patients (AUC = 0.850; P < 0.001). However, the combination of all 3 biomarkers obtained the most optimal results for predicting HCC onset, in terms of predictive capability for all 3 non-HCC patient groups, yielding AUCs of 0.958, 0.898, and 0.808 (P < 0.001) for, respectively, healthy, CH, and LC patients. Additionally, AFP had higher specificity, but lower sensitivity, with increased threshold values, as the recommended threshold of AFP ≥ 400 ng/mL yielded a missed diagnosis rate of 72.7%. For AFP-negative HCC (AFP-NHCC) patients, G-test alone had the greatest diagnostic capability (AUC = 0.855; P < 0.001), sensitivity (83.8%), and specificity (87.5%).ConclusionG-test has the greatest diagnostic capability for HCC and AFP-NHCC, with high sensitivity and specificity, among healthy and LC patients. However, AAR had the highest diagnostic capability and sensitivity for HCC in CH. Overall, though, the combination of G-test, AFP and AAR provided the most optimal outcomes for predicting HCC onset, no matter the patient pre-conditions.

Salivary orosomucoid 1 as a biomarker of hepatitis B associated hepatocellular carcinoma

Saliva is rich in proteins, DNA, RNA and microorganisms, and can be regarded as a biomarker library. In order to explore a noninvasive and simple means of early screening for liver cancer, proteomics was used to screen salivary markers of hepatitis B associated liver cancer. We used mass spectrometry coupled isobaric tags for relative and absolute quantitation (iTRAQ)-technology to identify differentially expressed proteins (DEPs). Western blot, immunohistochemistry and enzyme linked immunosorbent assay were used to detect marker expression of in tissues and saliva. Statistical analysis was used to analyze the diagnostic efficacy of the markers was analyzed through statistical analyses. By comparing the hepatocellular carcinoma (HCC) group with non-HCC groups, we screened out 152 salivary DEPs. We found orosomucoid 1(ORM1) had significantly higher expression in saliva of HCC patients compared with non-HCC groups (p < 0.001) and the expression of ORM1 in liver cancer tissues was significantly higher than that in adjacent normal tissues (p < 0.001). The combination of salivary ORM1 and alpha-fetoprotein (AFP) showed reasonable specificities and sensitivities for detecting HCC. In a word, salivary ORM1 as a new biomarker of hepatitis B associated hepatocellular carcinoma, combination of salivary ORM1 and AFP as an improved diagnostic tool for hepatocellular carcinoma.

Older Age and High α-Fetoprotein Predict Higher Risk of Hepatocellular Carcinoma in Chronic Hepatitis-B-Related Cirrhotic Patients Receiving Long-Term Nucleos(t)ide Analogue Therapy.

Background: Nucleos(t)ide analogues (NUCs) were proved to reduce hepatocellular carcinoma (HCC) development in chronic hepatitis B (CHB) patients, but data were limited on their efficacy in cirrhotic CHB patients. Methods: A total of 447 cirrhotic CHB patients treated with tenofovir/entecavir were retrospectively analyzed and divided into HCC (n = 48) and non-HCC (n = 399) groups. The median follow-up period was 62.1 months. Results: A total of 48 patients (10.7%) developed HCC during surveillance. The annual incidence rate of HCC was 2.04 per 100 person-years. The cumulative incidence of HCC was 0.9%, 9.8%, and 22.1% at 1, 5, and 10 years, respectively. Significant predictors for HCC identified using a multiple Cox regression analysis were age ≥50 years (hazard ratio (HR): 2.34) and α-fetoprotein (AFP) ≥8 ng/mL (HR: 2.05). The incidence rate of HCC was 8.67-fold higher in patients with age ≥50 years and AFP ≥8 ng/mL (3.14 per 100 person-years) than those with age <50 years and AFP <8 ng/mL (0.36 per 100 person-years). Conclusions: Cirrhotic CHB patients with age <50 years and AFP <8 ng/mL had the lowest annual incidence of HCC. However, those with age ≥50 years or/and AFP ≥8 ng/mL had a significantly higher risk for HCC development and warrant a careful surveillance schedule.
