Ataxia with oculomotor apraxia type 2 caused by a novel homozygous mutation in SETX gene, and literature review.

Autosomal recessive inherited ataxia with oculomotor apraxia type 2 (AOA2), caused by SETX gene mutations, is characterized by early-onset, progressive cerebellar ataxia, peripheral neuropathy, oculomotor apraxia and elevated serum α-fetoprotein (AFP). This study aimed to expand and summarize the clinical and genetic characteristics of SETX variants related to AOA2. The biochemical parameters, electromyogram and radiological findings of the patient were evaluated. Whole-exome sequencing (WES) was performed on the patient using next-generation sequencing (NGS), the variants were confirmed by Sanger sequencing and the pathogenicity of the variants was classified according to the American College of Medical Genetics and Genomics/Association for Molecular Pathology (ACMG/AMP) guidelines. We reviewed 57 studies of AOA2 patients with SETX mutations and collected clinical and genetic information. The patient was a 40-year-old Chinese woman who primarily presented with numbness and weakness of the lower limbs in her teenage years. She had elevated AFP, increased serum follicle-stimulating hormone (FSH) and luteinizing hormone (LH) and decreased anti-Müllerian hormone (AMH) levels. We identified a novel homozygous missense mutation of the SETX gene, c.7118 C>T (p. Thr2373Ile), in the patient via Whole-exome and Sanger sequencing. The variant was located in the DNA/RNA helicase domain and is highly conserved. The protein prediction analysis verified the SETX variant as a damaging alteration and ACMG/AMP guidelines classified it as likely pathogenic. Through a literature review, we identified 229 AOA2 cases with SETX variants, and among the variants, 156 SETX variants were exonic. We found that 107 (46.7%) patients were European, 50 (21.8%) were African and 48 (21.0%) were Asian. Among the Asian patients, five from two families were Mainland Chinese. The main clinical features were cerebellar ataxia (100%), peripheral neuropathy (94.6%), cerebellar atrophy (95.3%) and elevated AFP concentration (92.0%). Most reported SETX mutations in AOA2 patients were missense, frameshift and nonsense mutations. We discovered a novel homozygous variant of the SETX gene as a cause of AOA2 in the current patient and expanded the genotypic spectrum of AOA2. Moreover, the clinical features of AOA2 and genetic findings in SETX were assessed in reported cohorts and are summarized in the present study.

Maternal Serum α-Fetoprotein Levels during Pregnancy and Testicular Cancer in Male Offspring: A Cohort Study within a Danish Pregnancy Screening Registry.

Testicular cancer is believed to originate from disruptions of normal androgen-estrogen balance in-utero. α-fetoprotein (AFP) may modify fetal response to estrogens via estrogen interaction. In a cohort study, we investigated the association between circulating maternal pregnancy AFP and testicular cancer risk in offspring. Of the 56,709 live-born males from a pregnancy screening registry in 1980-1995, our study included 50,519 singleton males with available second trimester blood samples from their mothers and complete covariate ascertainment. Testicular cancer diagnoses and covariate data were obtained from nationwide Danish health registries. Cox regression and Kaplan-Meier analyses estimated the prospective risk of testicular cancer (all, seminoma, nonseminoma) by AFP multiples of the median. During follow-up, 163 (0.3%) of the included males developed testicular cancer, of which 89 (54.6%) were nonseminomas. Maternal serum AFP levels greater than/equal to the median were associated with a relative risk of testicular cancer close to unity (RR 1.04, 95% CI 0.76; 1.41) compared to AFP below the median. Associations differed by type of testicular cancer (RRseminoma 0.81, 95% CI 0.51; 1.29, RRnonseminoma 1.31, 95% CI 0.85; 2.02). On balance, our findings do not support that serum AFP in pregnancy can be used as a predictor of testicular cancer in offspring.

Optimizing Imaging of Pediatric Liver Lesions: Guidelines from the Pediatric LI-RADS Working Group.

A differential diagnosis based on a patient's age, clinical presentation, and serum α-fetoprotein level will help guide the initial imaging workup in children with a liver lesion. Children vary significantly in size, the ability to stay still, and the ability to breath hold for imaging examinations. Choosing and tailoring imaging techniques and protocols for each indication and age group is important for optimal care with minimal invasiveness. The need for sedation or anesthesia can be obviated by using techniques like feed and bundle, distraction, contrast-enhanced US, and motion-insensitive sequences for MRI. US is often the first imaging modality used in children with a suspected abdominal mass. Once a hepatic lesion is confirmed, multiphasic contrast-enhanced MRI is recommended for most lesions as the next imaging modality allowing full characterization of the lesion and assessment of the liver parenchyma. Contrast-enhanced CT can also be performed for assessment of pediatric focal liver lesions, especially in patients who have a contraindication to MRI. Contrast-enhanced US has shown promise to decrease the need for MRI or CT in some lesions such as hemangioma and focal nodular hyperplasia. Children with a history of malignancy can develop multiple types of hepatic lesions at various stages, including infections during an immunocompromised state, manifesting as focal liver lesions. Based on available limited data in the literature and the collective experiences of the Liver Imaging and Reporting Data System Pediatric Working Group, the authors provide guidelines for the imaging workup of pediatric focal liver lesions with an indication- and age-based approach and discuss the selection and performance of various imaging techniques and modalities. ©RSNA, 2022 See the invited commentary by Chojniak and Boaventura in this issue.

Gundelia tournefortii inhibits hepatocellular carcinoma progression by lowering gene expression of the cell cycle and hepatocyte proliferation in immunodeficient mice

Gundelia (G.) tournefortii has antibacterial, anti-inflammatory, and hypolipemic effects. We evaluated the anticancer effect of G. tournefortii in an hepatocellular carcinoma (HCC) mouse model of an HCC cell line (Hep3B) injected into NOD.CB17-Prkdc-SCID/NCrHsD male mice. Tumorigenicity was assessed by tumor size, histology, serum α-fetoprotein (αFP), and glypican 3 (GPC3). HCC-related gene expression of the cell cycle (Cyclin-dependent kinase inhibitor 2A (CDNK2A)), proliferation (MKI67), and platelet-derived growth factor receptor α (PDGFA) were measured. HCC cell cycle alterations, apoptosis, and antioxidant markers in serum and liver following treatment with G. tournefortii were determined. Signaling pathways of liver p53 and phosphorylated PI3K, AKT, and mTOR were also evaluated. Results indicate a significant increase in tumor size in HCC animals associated with elevated αFP, GPC3, and MKI67. Tumor markers of p53 and phosphorylated AKT/PI3K/mTOR signaling pathway were diminished, with less proliferating cells and reduced PDGFRA gene expression following G. tournefortii infection. H&E staining showed a remarkable reduction in inflammatory lesions in HCC mice treated with G. tournefortii. This result was in line with a significant delay in the G2/M phase of HCC-primary hepatocytes by 1.39- to 2.4-fold and reduced HCC necrosis associated with inhibited CDNK2A gene expression. Antioxidant activity was significantly lower in the HCC mice than in the control group. Moreover, G. tournefortii inhibited the HCC formation of 3D MCTS spheroids. G. tournefortii treatment markedly restored antioxidant levels and displayed anticancer and antiproliferative effects and could be a promising cancer therapy.

Dynamic CT and Gadoxetic Acid-enhanced MRI Characteristics of P53-mutated Hepatocellular Carcinoma.

Background Imaging markers of hepatocellular carcinoma (HCC) on the basis of molecular classification are important for predicting malignancy grade and prognosis. P53-mutated HCC is a major aggressive subtype; however, its imaging characteristics have not been clarified. Purpose To clarify the imaging characteristics of P53-mutated HCC at dynamic CT and gadoxetic acid-enhanced MRI that are correlated with its clinical features, pathologic findings, and prognosis. Materials and Methods In this retrospective single-center study, patients with surgically resected HCC between January 2015 and May 2018 in a university hospital were evaluated. HCC was classified into P53-mutated HCC and non-P53-mutated HCC using immunostaining. Dynamic CT and gadoxetic acid-enhanced MRI findings, clinical features, pathologic findings, and prognosis were compared using Mann-Whitney test, χ2 test, multivariable regression analysis, receiver operating characteristic analysis, Kaplan-Meier method, and log-rank test. Immunohistochemical expression of P53, organic anion transporting polypeptide 1B3 (OATP1B3), and CD34 were evaluated, and the correlations were analyzed using the Pearson correlation test. Results In total, 149 patients (mean age, 67 years ± 9 [SD]; 103 men) with 173 HCCs were evaluated. P53-mutated HCC (n = 28) demonstrated higher serum α-fetoprotein (median, 127.5 ng/mL vs 5.5 ng/mL; P < .001), larger size (40.4 mm ± 29.7 vs 26.4 mm ± 20.5; P = .001), and higher rates of poorly differentiated HCC (22 of 28 [79%] vs 24 of 145 [17%]; P < .001). Dilated vasculature in the arterial phase of dynamic CT (odds ratio, 14; 95% CI: 3, 80; P = .002) and a lower relative enhancement ratio in the hepatobiliary phase (odds ratio, 0.05; 95% CI: 0.01, 0.34; cutoff value, 0.69; P = .002) independently predicted P53-mutated HCC. OATP1B3 expression and P53 expression were inversely correlated (P = .002; R = -0.24). Five-year overall survival was worse for P53-mutated HCC (50.0% vs 72.6%; P = .02). Conclusion Dilated vasculature at the arterial phase of dynamic CT and a lower relative enhancement ratio at the hepatobiliary phase of gadoxetic acid-enhanced MRI were useful markers for P53-mutated hepatocellular carcinoma with poor prognosis. © RSNA, 2022 Online supplemental material is available for this article.

Inhibition of induced-hepatic cancer in vivo through IQGAP1-shRNA gene therapy and modulation of TRAIL-induced apoptosis pathway.

BackgroundLiver cancer is the deadliest malignancy among common tumors. It is the top cause of cancer-related deaths in Egypt, and it is characterized by increasing occurrence among the population. The objective of this study was to determine the outcome of pre-treatment of IQGAP1-shRNA on induced mouse hepatocellular carcinoma model and evaluate the potency of this IQGAP1-shRNA plasmid to recover hepatic cancer as a new tool of cancer therapy. Therefore, we will use RNA interference (RNAi) technology to silence IQGAP1 oncogene to completely recover the chemically induced models for hepatic cancer by designing short RNAi specific for IQGAP1 gene in HCC cells in vivo and construct new vectors suitable for this purpose. We assigned mice into three groups: the first negative control group (NC) was injected with saline, the second control group was injected with shRNA (shNC), the third positive control group was injected with diethylnitrosamine (DENAA), and the fourth group was treated with the IQGAP1-shRNA prior to its exposure to DENA.ResultsOur results revealed that the treated group with IQGAP1-shRNA with DENA developed very few cases of hepatic cancer when compared with the positive control group. The positive control group exhibited significant increases in the liver function level as well as a decrease in serum albumin levels when compared to both the treated and the negative control groups. The altered levels of the serum α-fetoprotein as well as of the tumor necrosis factor-alpha, and interleukin-4 in DENA-treated mice were significantly ameliorated by IQGAP1-shRNA administration. Flow cytometer analyses have indicated that the silencing of IQGAP1 cannot significantly modulate DENA-induced apoptosis in the circulating blood cells. Moreover, the elevated mRNA expression levels of IQGAP1, IQGAP3, KRas, HRas, interleukin-8, nuclear factor kappa B, caspase-3, caspase-9 and Bcl-2, were significantly decreased by the IQGAP1-shRNA treatment. However, the IQGAP2, DR4, DR5, p53 and BAX genes were found to be significantly up-regulated post-therapy. In agreement with these findings, IQGAP1-shRNA was able to modulate the DENA-induced histological changes in the mice liver which were represented by severe necrosis and hydropic degenerative changes.ConclusionOur study revealed that IQGAP1-shRNA was able to preserve hepatocyte integrity and the liver histological architecture through the regulation of the expression of IQGAPs, Ras, TRAILs and IL-8 receptors, as well as of pro-apoptotic and anti-apoptotic genes. Therefore, the silencing of IQGAP1 could be part of a promising therapeutic strategy against hepatic cancer.

Role of Tri-Phasic Computed Tomography in Evaluation of Hepatocellular Carcinoma Patients with Liver Cirrhosis

OBJECTIVESTo assess the usefulness of Tri-phasic computed tomography in the evaluation of hepatocellular carcinoma in cirrhotic patients.METHODOLOGYThis cross-sectional study was carried out in the Radiology and Imaging Department of Hayatabad Medical Complex Peshawar from October 2020 to September 2021 (01 year). Tri-phasic CT was done in all patients. Patients with suspected hepatocellular carcinoma diagnosed by clinical and ultrasonography and having high serum α-fetoprotein levels were enrolled in the study.RESULTSMalignant cases on tri-phasic CT were 120(82.8%) while benign cases were 25 (17.2%) Fig -I. In malignant tumor cases, 99(82.5%) patients had hepatocellular carcinoma (HCC), 13(10.8%) had metastases and 8(6.7%) had dysplastic nodule respectively. In benign tumour cases, 15(60%) had regenerative nodules, 6(24%) had hepatic adenoma and 4 (16%) had haemangioma. Tri -phasic CT as a tool in the diagnosis of hepatocellular carcinoma in cirrhotic patients showed a sensitivity of 96.8%, specificity of 79.7%, the accuracy of 95%, positive predictive values of 96.2% and negative predictive values of 88.1%.CONCLUSIONTri-Phasic CT can be an ideal diagnostic tool for detecting as well as characterizing hepatocellular carcinoma in cirrhotic patients.

The Characteristics and Mortality of Chinese Herbal Medicine Users among Newly Diagnosed Inoperable Huge Hepatocellular Carcinoma (≥10 cm) Patients: A Retrospective Cohort Study with Exploration of Core Herbs.

For patients with inoperable huge hepatocellular carcinoma (H-HCC, tumor size ≥10 cm), treatment options are limited. This study aimed to evaluate the characteristics and outcomes of patients with H-HCC who use Chinese herbal medicine (CHM). Multi-institutional cohort data were obtained from the Chang Gung Research Database (CGRD) between 1 January 2002 and 31 December 2018. All patients were followed up for 3 years or until the occurrence of death. Characteristics of CHM users and risk of all-cause mortality were assessed, and core CHMs with potential pharmacologic pathways were explored. Among 1618 patients, clinical features of CHM users (88) and nonusers (1530) were similar except for lower serum α-fetoprotein (AFP) and higher serum albumin levels in CHM users. CHM users had significantly higher 3 year overall survival rates (15.0% vs. 9.7%) and 3 year liver-specific survival rates (13.4% vs. 10.7%), about 3 months longer median survival time, and lower risk of all-cause mortality. Core CHMs were discovered from the prescriptions, including Hedyotis diffusa Willd combined with Scutellaria barbata D.Don, Salvia miltiorrhiza Bunge., Curcuma longa L., Rheum palmatum L., and Astragalus mongholicus Bunge. CHM use appears safe and is possibly beneficial for inoperable H-HCC patients; however, further clinical trials are still required.

A combination of hepatic encephalopathy and body mass index was associated with the point of no return for improving liver functional reserve after sofosbuvir/velpatasvir treatment in patients with hepatitisC virus-related decompensated cirrhosis.

The real-world efficacy of sofosbuvir/velpatasvir treatment for patients with hepatitisC virus-related decompensated cirrhosis is unclear. We aimed to identify factors that improve liver functional reserve after treatment. This was a multicenter retrospective study of 12-week sofosbuvir/velpatasvir treatment. A total of 48 patients with Child-Pugh (CP) class B or C were enrolled at 11 institutions. We evaluated changes in liver functional reserve at 24weeks post-treatment. At baseline, 40 and eight patients were CP class B and C, respectively. The overall rate of sustained virologic response 12weeks post-treatment was 95.8% (46/48). Serum albumin, alanine aminotransferase and α-fetoprotein levels, and the FIB-4 index were significantly improved post-treatment (P<0.05). Among patients who achieved sustained virologic response 12weeks post-treatment, those with CP class A increased from 0 to 24 patients (56%) at 24weeks post-treatment. In multivariate analysis, body mass index (BMI) ≥25 was an independent factor that inhibited CP class improvement (P<0.05). In decision tree analysis, after treatment, the initial divergent variable for CP class improvement was hepatic encephalopathy, followed by serum sodium level and BMI. Sofosbuvir/velpatasvir treatment improved the liver functional reserve in patients with hepatitisC virus-related decompensated cirrhosis at 24weeks post-treatment. However, BMI ≥25 inhibited improvement in CP class. Additionally, decision tree analysis revealed that a combination of hepatic encephalopathy, serum sodium levels, and BMI were diversity profiles associated with no improvement in liver functional reserve after the treatment.

HBx and YAP expression could promote tumor development and progression in HBV-related hepatocellular carcinoma

BackgroundHepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) accounts for 10%–20% of the total HCC numbers. Its clinical features include the occurrence in the younger generation, large tumors, and poor prognosis. The contribution of hepatitis B virus X (HBx) protein in hepatocytes during activation of various oncogenic pathways has been reported. We aimed to assess the possible association between HBx and Yes-associated protein (YAP) expression in the liver tissue and the clinical features of HBV-related HCC. MethodsThe relationship between HBx and YAP expression was examined in vivo using HCC tumor and peritumor tissues (n = 55). The clinical information including tumor size, marker, and the prognosis was assessed with protein expressions. The in vitro gene expression analyses were conducted using HBx- and YAP-overexpressing HCC cell lines. ResultsAmong 19 cases of HBV-related, 17 cases of hepatitis C virus (HCV)-related, and 19 cases of nonviral-related HCC, the HBV-related tumor showed the largest size. The HBx-stained area in the tumor and peritumor tissue showed a significant correlation with tumor size and serum α-fetoprotein level. YAP expression was higher in HBV-related tumor tissue than in the peritumor tissue and HCV-related tumor. Additionally, HBx and YAP protein expressions are correlated and both expressions in the tumor contributed to the poor prognosis. An in vitro study demonstrated that HBx and YAP overexpression in the hepatocytes activate the various oncogenic signaling pathways. ConclusionsOur study demonstrated that YAP expression in the liver of HBV-infected patients might be the key factor in HBV-related HCC development and control of tumor-related features.

LncRNA HULC and miR-122 Expression Pattern in HCC-Related HCV Egyptian Patients

Hepatocellular carcinoma (HCC) is a highly prevalent malignancy. It is a common type of cancer in Egypt due to chronic virus C infection (HCV). Currently, the frequently used lab test is serum α-fetoprotein. However, its diagnostic value is challenging due to its low sensitivity and specificity. Genetic biomarkers have recently provided new insights for cancer diagnostics. Herein, we quantified Lnc HULC and miR-122 gene expression to test their potential in diagnosis. Both biomarkers were tested in the sera of 60 HCC patients and 60 with chronic HCV using real-time RT-PCR. miR-122 was highly expressed in HCV patients with a significant difference from the HCC group (p = 0.004), which points towards its role in prognosis value as a predictor of HCC in patients with chronic HCV. HULC was more highly expressed in HCC patients than in the HCV group (p = 0.018), indicating its potential use in screening and the early diagnosis of HCC. The receiver operating characteristic (ROC) curve analysis showed their reliable sensitivity and specificity. Our results reveal that miR-122 can act as a prognostic tool for patients with chronic HCV. Furthermore, it is an early predictor of HCC. LncRNA HULC can be used as an early diagnostic tool for HCC.

Radiofrequency Ablation versus Transarterial Chemoembolization for Hepatocellular Carcinoma within Milan Criteria: Prognostic Role of Tumor Burden Score.

Simple SummaryTumor burden score (TBS) has been recently introduced to assess the tumor burden in hepatocellular carcinoma (HCC), but its prognostic role in patients with early-stage HCC is unclear. We confirm that TBS is an independent prognostic predictor in HCC patients within the Milan criteria undergoing radiofrequency ablation (RFA) or transarterial chemoembolization (TACE). TACE may be an effective treatment alternative for these patients. Among patients with low TBS, RFA should be considered the priority treatment modality.Tumor burden score (TBS), estimated by the diameter and number of tumor nodules, was recently proposed to assess the tumor burden in hepatocellular carcinoma (HCC). We aimed to evaluate the prognostic impact of TBS on HCC patients within the Milan criteria undergoing radiofrequency ablation (RFA) or transarterial chemoembolization (TACE). A total of 883 patients undergoing RFA and TACE were included. The multivariate Cox proportional hazards model was used to determine independent prognostic predictors in different patient cohorts. The TACE group had significantly higher TBS compared with the RFA group. The RFA group had better long-term survival than the TACE group in patients within the Milan criteria in univariate survival analysis. In the Cox model, serum α-fetoprotein (AFP) > 20 ng/mL, performance status 1–2, medium and high TBS, albumin–bilirubin (ALBI) grade 2 and grade 3 were independent predictors linked with mortality (all p < 0.001). Overall, TACE was not an independent predictor; among patients with low TBS, TACE was independently associated with decreased survival compared with RFA (p = 0.034). Conclusions: TBS is a feasible prognostic marker for HCC patients within the Milan criteria. TACE may be an effective treatment alternative for these patients. Among patients with low TBS, RFA should be considered the priority treatment modality.

Incidence and risk factors of hepatocellular carcinoma in patients with hepatitis C who achieved a sustained virological response through direct-acting antiviral agents among the working population in Japan.

Background and AimThe development of hepatocarcinogenesis after a sustained virological response (SVR) remains an important issue affecting the balance between treatment and occupational life of workers with chronic hepatitis C virus (HCV) infection in Japan. Here, we aimed to evaluate the hepatocellular carcinoma (HCC) reducing effect and risk factors for developing HCC after SVR in patients treated with direct‐acting antiviral agents (DAAs) among the working population.MethodsWe studied 2579 working patients with chronic HCV infection who achieved SVR after antiviral treatment. We compared the difference in the cumulative incidence of post‐SVR HCC between the interferon (IFN)‐based n = 1615 and DAA (n = 964) groups. The risk factors for post‐SVR HCC development were determined in the DAA group.ResultsAfter propensity score matching (n = 644 in each group), the HCC development rates were not significantly different between the groups (P = 0.186). Multivariate Cox regression and the cutoff values determined by the receiver operating characteristic curve analyses revealed that age ≥61 years, diabetes, lower serum albumin levels <4.0 g/dL at 24 weeks after the end of treatment (EOT), and higher serum α‐fetoprotein levels ≥4.1 ng/mL at 24 weeks after the EOT were associated with the development of HCC.ConclusionThe HCC suppressing effect after SVR through DAA treatment is equivalent to that of IFN treatment in patients in the working population. Intensive follow‐up is required after SVR with DAA treatment in Japanese workers with these risk factors to ensure the promotion of health and employment support.

Usefulness of AFP, PIVKA-II, and Their Combination in Diagnosing Hepatocellular Carcinoma Based on Upconversion Luminescence Immunochromatography.

To evaluate the prognostic values of serum PIVKA-II (prothrombin induced by vitamin K absence-II) and α-fetoprotein (AFP) and the combination of these analytes for identifying hepatocellular carcinoma (HCC), and to analyze the correlation between biomarkers and clinicopathological features of HCC. The levels of PIVKA-II and AFP in 331 case individuals were determined by upconverting phosphor technology-based immune lateral flow (UPT-LF) assay. We used the ROC curve to determine the diagnostic value; the relationships between the biomarkers and clinicopathological features of HCC also were analyzed. AFP and PIVKA-II have good diagnostic performance in the diagnosis of HCC; the best AUC was 0.76, 0.74. High levels of PIVKA-II were more advantageous than AFP in predicting tumor size, portal-vein embolism, and vascular invasion (all P <.05). Levels of PIVKA-II and AFP showed good diagnostic value for HCC, but the level of PIVKA-II was more closely related to the clinicopathological features of HCC.

Predictive value of serum alpha-fetoprotein for tumor regression after preoperative chemotherapy for rectal cancer.

BACKGROUNDPreoperative therapy is widely used in locally advanced rectal cancer. It can improve local control of rectal cancer. However, there are few indicators that can predict the effect of preoperative chemotherapy accurately.AIMTo investigate whether the increase in serum α-fetoprotein (AFP) can predict better efficacy of preoperative chemotherapy.METHODSThis was a retrospective study. We analyzed 125 patients admitted between 2017 and 2019 with locally advanced rectal cancer. All patients received six cycles of preoperative chemotherapy (mFOLFOX6 every 2 wk). Serum AFP of 26 patients rose slightly after three or four cycles of chemotherapy, and fell to normal again within 2 mo. The other 99 patients had a normal level of serum AFP during chemotherapy. Patients were divided into two groups (AFP risen and AFP normal). According to postoperative pathology, we compared tumor regression and complete response rate between the two groups. The primary outcome measure was the tumor regression grade (TRG) after chemotherapy. The difference in pathological complete response between the two groups was also investigated.RESULTSThere were no tumor progression and distant metastasis in both groups during preoperative chemotherapy. Patients in the AFP risen group achieved better TRG 0/1 than those in the AFP normal group (61.5% vs 39.4%). The increase in AFP was a significant predictor for better tumor regression [χ2 = 4.144, odds ratio (OR) = 2.666, P = 0.04]. In the AFP risen group, the complete response rate was 30.8%, which was higher than in the AFP normal group (30.8% vs 12.1%, χ2 = 4.542, OR = 3.251, P = 0.03).CONCLUSIONPatients with a slight increase in serum AFP can achieve better tumor regression during preoperative chemotherapy, and are more likely to achieve pathological complete response.

Safety of ramucirumab treatment in patients with advanced hepatocellular carcinoma and elevated alpha-fetoprotein

ABSTRACT Introduction Hepatocellular carcinoma (HCC) is the second most common cause of cancer-induced deaths worldwide, and limited therapeutic options are available for patients with advanced disease. Ramucirumab, a monoclonal antibody that blocks the vascular endothelial growth factor (VEGF) receptor-2, is the first biomarker-selected systemic agent with therapeutic efficacy, tolerability, and favorable patient-reported outcomes in patients with advanced HCC and elevated serum α-fetoprotein levels ≥400 ng/mL, who are resistant or intolerant to sorafenib therapy. However, treatment-induced adverse events (AEs), such as hypertension, proteinuria, bleeding, thromboembolism, and gastrointestinal perforation remain challenging and potentially fatal concerns. Areas covered This review discusses the published or ongoing studies and subgroup analyses on ramucirumab therapy in patients with advanced HCC. We present information on the risks of ramucirumab-induced common or rare AEs and their management. Expert opinion Ramucirumab toxicity secondary to VEGF inhibition is similar to the AEs that are known to be associated with other VEGF-blocking antibodies. Common AEs can be safely treated using conventional measures; however, rare and potentially fatal AEs necessitate close monitoring. With regard to the safety profile, more promising ramucirumab-containing combination therapies are likely to pave the future path for effective HCC treatment.

A New Tumor Burden Score and Albumin-Bilirubin Grade-Based Prognostic Model for Hepatocellular Carcinoma.

Simple SummaryThe survival of patients with hepatocellular carcinoma (HCC) is highly variables, due to heterogeneous tumor burden and liver dysfunction. Tumor burden score (TBS) is a continuous variable to measure the extent of tumor involvement, and the albumin–bilirubin (ALBI) grade is an objective model to estimate hepatic functional reserve. Six prognostic predictors—including TBS, ALBI grade, ascites, serum α-fetoprotein level, vascular invasion or distant metastasis, and performance status—were linked with survival in a multivariate Cox model. We used these predictors to establish a new prognostic model—the TBS–ALBI system—to predict patient outcomes. Significant survival differences were found in different TBS–ALBI scores in the derivation and validation cohorts. This new system can also discriminate survival differences in patients with different viral etiologies, cancer stages, and treatment modalities. This study shows that the TBS–ALBI system is a feasible and user-friendly prognostic model for HCC.The prognosis of hepatocellular carcinoma (HCC) varies widely due to variable tumor extent and liver reserve. We aimed to develop and validate a new prognostic model based on tumor burden score (TBS) and albumin–bilirubin (ALBI) grade for HCC. We prospectively identified 3794 HCC patients who were randomized into derivation and validation groups. Survival predictors were evaluated by a multivariate Cox model. The TBS–ALBI system allocated two points for high TBS and ALBI grade 3, and one point each for the presence of ascites, serum α-fetoprotein ≥ 400 ng/mL, vascular invasion or distant metastasis, performance status 2–4, medium TBS, and ALBI grade 2, with a maximal score of 8 points. Significant survival differences were found across different TBS–ALBI score groups in the validation cohort (all p < 0.001). The TBS–ALBI system had the lowest corrected Akaike information criterion (AICc) and the highest homogeneity compared with other proposed staging models. The discriminative ability of the TBS–ALBI system was consistently stable across different viral etiologies, cancer stages, and treatment strategies. Conclusions: This new TBS–ALBI system is a feasible and robust prognostic system in comparison with other systems; it is a user-friendly tool for long-term outcome assessment independent of treatment modality and cancer stage in HCC.

Diagnostic and prognostic value of serum Chitinase 3-like protein 1 in hepatocellular carcinoma.

The serum Chitinase 3‐like protein 1 (CHI3L1) protein level can distinguish the stages of liver fibrosis to a great extent. However, the diagnostic and prognostic significance of serum CHI3L1 in hepatocellular carcinoma (HCC) is not clarified. To evaluate the diagnostic and prognostic value of CHI3L1 in HCC, a total of 128 HCC patients treated in the HwaMei Hospital, University of Chinese Academy of Sciences, from December 2018 to April 2020 were collected retrospectively. Matched age and gender subjects, 40 patients with liver cirrhosis, 40 patients with chronic hepatitis, and 40 healthy subjects were enrolled in the control group. The relevant clinical laboratory and examination data and the overall survival time (OS) of the HCC patients were collected. The serum CHI3L1 expression level is related to α‐fetoprotein (AFP), tumor‐node‐metastasis (TNM) stage, maximum tumor diameter, liver cirrhosis, and HCC patient's OS (p < 0.05). The area under the curve (AUC) of CHI3L1 was 0.7875 with the cutoff value of 91.36 ng/ml. Combining the serum CHI3L1 and α‐fetoprotein (AFP) by a binary logistic regression model can increase the diagnostic sensitivity to 97.5%. Multivariate Cox regression analysis indicated that CHI3L1 is an independent prognostic factor in patients with HCC.
