RESUMEN
Background: Advanced hepatocellular carcinoma (HCC) is characterized as symptomatic tumors [performance status (PS) score of 1-2], vascular invasion and extrahepatic spread, but patients with PS1 alone may be eliminated from this stage. Although liver resection is used for liver-confined HCC, its role in patients with PS1 alone remains controversial. Therefore, we aimed to explore its application in such patients and identify potential candidates. Methods: Eligible liver-confined HCC patients undergoing liver resection were retrospectively screened in 15 Chinese tertiary hospitals, with limited tumor burden, liver function and PS scores. Cox-regression survival analysis was used to investigate the prognostic factors and develop a risk-scoring system, according to which patients were substratified using fitting curves and the predictive values of PS were explored in each stratification. Results: From January 2010 to October 2021, 1535 consecutive patients were selected. In the whole cohort, PS, AFP, tumor size and albumin were correlated with survival (adjusted P<0.05), based on which risk scores of every patient were calculated and ranged from 0 to 18. Fitting curve analysis demonstrated that the prognostic abilities of PS varied with risk scores and that the patients should be divided into three risk stratifications. Importantly, in the low-risk stratification, PS lost its prognostic value, and patients with PS1 alone achieved a satisfactory 5-year survival rate of 78.0%, which was comparable with that PS0 patients (84.6%). Conclusion: Selected patients with PS1 alone and an ideal baseline condition may benefit from liver resection and may migrate forward to BCLC stage A.
RESUMEN
Introduction: Lenvatinib is the first-line treatment for advanced hepatocellular carcinoma (HCC). We aimed to compare the clinical outcomes of lenvatinib plus drug-eluting beads transarterial chemoembolization (DEB-TACE) versus lenvatinib alone in real-world practice. Methods: This retrospective analysis included 142 consecutive patients who received lenvatinib plus DEB-TACE and 69 patients who received lenvatinib alone as first-line treatment from 15 Chinese academic centers from November 2018 to November 2019. Overall survival (OS), progression-free survival (PFS), objective response rate (ORR) were evaluated by modified Response Evaluation Criteria in Solid Tumors criteria, and safety profiles were compared between the two groups. Results: The median OS and PFS were significantly longer in the combined therapy group than in the monotherapy group in whole cohort (median OS, 15.9 vs. 8.6 months, p = 0.0022; median PFS, 8.6 vs. 4.4 months, p < 0.001) and after propensity score matching analysis (median OS, 13.8 vs. 7.8 months, p = 0.03; median PFS, 7.8 vs. 4.5 months, p = 0.009). Moreover, the treatment option was an independent prognostic factor for OS and PFS with adjustment based upon baseline characteristics (adjusted hazard ratio [HR]: 0.53, 95% confidence interval [CI]: 0.36-0.78, p = 0.001, and adjusted HR: 0.42, 95% CI: 0.30-0.60, p < 0.001, respectively) and propensity score (adjusted HR: 0.52, 95% CI: 0.36-0.76, p = 0.001, and adjusted HR: 0.46, 95% CI: 0.33-0.64, p < 0.001, respectively). Moreover, a greater ORR was observed in the combined group (ORR: 46.48% vs. 13.05%, p < 0.001). Furthermore, the most common adverse events (AEs) were elevated aspartate aminotransferase (54.9%) and fatigue (46.4%) in the lenvatinib plus DEB-TACE group and lenvatinib group, respectively. Most AEs were mild-to-moderate and manageable. Conclusions: With well-tolerated safety, lenvatinib plus DEB-TACE was more effective than lenvatinib monotherapy in improving OS, PFS, and ORR. Thus, it may be a promising treatment for advanced HCC. Future prospective studies confirming these findings are warranted.
RESUMEN
ABSTRACT: Information about coronavirus disease 2019 (COVID-19) patients with pre-existing chronic obstructive pulmonary disease (COPD) is still lacking. The aim of this study is to describe the clinical course and the outcome of COVID-19 patients with comorbid COPD.This retrospective study was performed at Wuhan Huoshenshan Hospital in China. Patients with a clear diagnosis of COVID-19 who had comorbid COPD (Nâ=â78) were identified. COVID-19 patients without COPD were randomly selected and matched by age and sex to those with COPD. Clinical data were analyzed and compared between the two groups. The composite outcome was the onset of intensive care unit admission, use of mechanical ventilation, or death during hospitalization. Multivariable Cox regression analyses controlling for comorbidities were performed to explore the relationship between comorbid COPD and clinical outcome of COVID-19.Compared to age- and sex-matched COVID-19 patients without pre-existing COPD, patients with pre-existing COPD were more likely to present with dyspnea, necessitate expectorants, sedatives, and mechanical ventilation, suggesting the existence of acute exacerbations of COPD (AECOPD). Greater proportions of patients with COPD developed respiratory failure and yielded poor clinical outcomes. However, laboratory tests did not show severer infection, over-activated inflammatory responses, and multi-organ injury in patients with COPD. Kaplan-Meier analyses showed patients with COPD exhibited longer viral clearance time in the respiratory tract. Multifactor regression analysis showed COPD was independently correlated with poor clinical outcomes.COVID-19 patients with pre-existing COPD are more vulnerable to AECOPD and subsequent respiratory failure, which is the main culprit for unfavorable clinical outcomes. However, COPD pathophysiology itself is not associated with over-activated inflammation status seen in severe COVID-19.

OBJECTIVES: Objective response rate (ORR) under mRECIST criteria after transarterial chemoembolization (TACE) is a well-perceived surrogate endpoint of overall survival (OS). However, its optimal time point remains controversial and may be influenced by tumor burden. We aim to investigate the surrogacy of initial/best ORR in relation to tumor burden. METHODS: A total of 1549 eligible treatment-naïve patients with unresectable hepatocellular carcinoma (HCC), Child-Pugh score ≤ 7, and performance status score ≤ 1 undergoing TACE between January 2010 and May 2016 from 17 academic hospitals were retrospectively analyzed. Based on "six-and-twelve" criteria, tumor burden was graded as low, intermediate, and high if the sum of the maximum tumor diameter and tumor number was ≤ 6, > 6 but ≤ 12, and > 12, respectively. RESULTS: Both initial and best ORRs interacted with tumor burden. Initial and best ORRs could equivalently predict and correlate with OS in low (adjusted HR, 2.55 and 2.95, respectively, both p < 0.001; R = 0.84, p = 0.035, and R = 0.97, p = 0.002, respectively) and intermediate strata (adjusted HR, 1.81 and 2.22, respectively, both p < 0.001; R = 0.74, p = 0.023, and R = 0.9, p = 0.002, respectively). For high strata, only best ORR exhibited qualified surrogacy (adjusted HR, 2.61, p < 0.001; R = 0.70, p = 0.035), whereas initial ORR was not significant (adjusted HR, 1.08, p = 0.357; R = 0.22, p = 0.54). CONCLUSIONS: ORR as surrogacy of OS is associated with tumor burden. For patients with low/intermediate tumor burden, initial ORR should be preferred in its early availability upon similar sensitivity, whereas for patients with high tumor burden, best ORR has optimal sensitivity. Timing of OR assessment should be tailored according to tumor burden. KEY POINTS: ⢠This is the first study utilizing individual patient data to comprehensively analyze the surrogacy of ORR with a long follow-up period. ⢠Optimal timing of ORR assessment for predicting survival should be tailored according to tumor burden. ⢠For patients with low and intermediate tumor burden, initial ORR is optimal for its timeliness upon similar sensitivity with best ORR. For patients with high tumor burden, best ORR has optimal sensitivity.

Background & Aims: Hepatic encephalopathy (HE) is a major complication after transjugular intrahepatic portosystemic shunt (TIPS) and is primarily influenced by the gut microbiota. We aimed to evaluate alterations in the microbiota after TIPS and the association between such alterations and HE. Methods: We conducted a prospective longitudinal study of 106 patients with cirrhosis receiving TIPS. Faecal samples were collected before and after TIPS, and the gut microbiota was analysed by 16S ribosomal RNA sequencing. Results: Among all patients, 33 developed HE (HE+ group) within 6 months after TIPS and 73 did not (HE- group), and 18 died during follow-up. After TIPS, the autochthonous taxa increased, whereas the potential pathogenic taxa decreased in the HE- group, and the autochthonous taxon Lachnospiraceae decreased in the HE+ group. Furthermore, synergism among harmful bacteria was observed in all patients, which was weakened in the HE- group (p <0.001) but enhanced in the HE+ group (p <0.01) after TIPS. Variations of 5 autochthonous taxa, namely, Coprococcus, Ruminococcus, Blautia, Ruminococcaceae_uncultured, and Roseburia, were negatively correlated with the severity of HE. Notably, increased abundances of Coprococcus and Ruminococcus were protective factors against HE, and the incidences of HE in patients with improved, stable, and deteriorated microbiota after TIPS were 13.3, 25.9, and 68.2%, respectively. Higher total bilirubin level, Child-Pugh score, model for end-stage liver disease score, Granulicatella, and Alistipes and lower Subdoligranulum before TIPS were the independent risk factors for death. Conclusions: Alterations in gut dysbiosis were negatively related to the occurrence and severity of post-TIPS HE, and the pre-TIPS microbiota were associated with death, suggesting the gut microbiota could be a promising potential biological target for screening suitable patients receiving TIPS and prevention and treatment of post-TIPS HE. Lay summary: Alterations in the gut microbiota after transjugular intrahepatic portosystemic shunt (TIPS) and the relationship between such alterations and post-TIPS hepatic encephalopathy (HE) remain unclear. We therefore performed this study and found that after TIPS, restoration of the gut microbiota, mainly characterised by expansion of autochthonous taxa, depletion of harmful taxa, and weakening of synergism among harmful bacteria, was inversely related to the occurrence and severity of post-TIPS HE.
RESUMEN
Background: Hepatoma arterial-embolization prognostic (HAP) series scores have been proposed for prognostic prediction in patients with unresectable hepatocellular carcinoma (uHCC) undergoing transarterial chemoembolization (TACE). However, their prognostic value in TACE plus sorafenib (TACE-S) remains unknown. Here, we aim to evaluate their prognostic performance in such conditions and identify the best model for this combination therapy. Methods: Between January 2012 and December 2018, consecutive patients with uHCC receiving TACE-S were recruited from 15 tertiary hospitals in China. Cox regression analyses were used to investigate the prognostic values of baseline factors and every scoring system. Their prognostic performance and discriminatory performance were evaluated and confirmed in subgroup analyses. Results: A total of 404 patients were enrolled. In the whole cohort, the median follow-up period was 44.2 (interquartile range (IQR), 33.2-60.7) months, the median overall survival (OS) time was 13.2 months, and 336 (83.2%) patients died at the end of the follow-up period. According to multivariate analyses, HAP series scores were independent prognostic indicators of OS. In addition, the C-index, Akaike information criterion (AIC) values, and time-dependent area under the receiver operating characteristic (ROC) curve (AUC) indicated that modified HAP (mHAP)-III had the best predictive performance. Furthermore, the results remained consistent in most subsets of patients. Conclusion: HAP series scores exhibited good predictive ability in uHCC patients accepting TACE-S, and the mHAP-III score was found to be superior to the other HAP series scores in predicting OS. Future prospective high-quality studies should be conducted to confirm our results and help with treatment decision-making.
RESUMEN
Background: Although laboratory tests have become an indispensable part in clinical practice, its application in severity classification and death risk stratification of COVID-19 remains unvalidated. This study aims to explore the significance of laboratory tests in the management of COVID-19. Methods: In 3,342 hospitalized patients with COVID-19, those of mild or moderate subtype were categorized into the non-severe group, while those of severe or critical subtype were categorized into the severe group. Initial laboratory data were analyzed and compared according to disease severity and outcome. Diagnostic models for the severe group were generated on risk factors identified by logistic regression and receiver operating characteristic (ROC) analyses. Cox regression and ROC analyses on risk factors were utilized to construct prognostic models. Results: In identification of patients in the severe group, while age, neutrophil-to-lymphocyte ratio, and α-hydroxybutyrate dehydrogenase were identified as independent predictors, the value of combination of them appears modest [area under the curve (AUC) = 0.694]. Further ROC analyses indicated that among patients in the severe group, laboratory indices had a favorable value in identifying patients of critical subtype rather than severe subtype. For death outcome, IL-6, co-existing cerebrovascular disease, prothrombin time activity, and urea nitrogen were independent risk factors. An IL-6 single-parameter model was finalized for distinguishing between fatal and recovered individuals (AUC = 0.953). Finally, a modified death risk stratification strategy based on clinical severity and IL-6 levels enables more identification of non-survivors in patients with non-critical disease. Conclusions: Laboratory screening provides a useful tool for COVID-19 management in identifying patients with critical condition and stratifying risk levels of death.
RESUMEN
BACKGROUND & AIMS: Hepatocellular carcinoma (HCC) is among the malignancies with the highest mortality. The key regulators and their interactive network in HCC pathogenesis remain unclear. Along with genetic mutations, aberrant epigenetic paradigms, including deregulated microRNAs (miRNAs), exert profound impacts on hepatocyte transformation and tumor microenvironment remodeling; however, the underlying mechanisms are largely uncharacterized. METHODS: We performed RNA sequencing on HCC specimens and bioinformatic analyses to identify tumor-associated miRNAs. The miRNA functional targets and their effects on tumor-infiltrating immune cells were investigated. The upstream events, particularly the epigenetic mechanisms responsible for miRNA deregulation in HCC, were explored. RESULTS: The miR-144/miR-451a cluster was downregulated in HCC and predicted a better HCC patient prognosis. These miRNAs promoted macrophage M1 polarization and antitumor activity by targeting hepatocyte growth factor (HGF) and macrophage migration inhibitory factor (MIF). The miR-144/miR-451a cluster and EZH2, the catalytic subunit of polycomb repressive complex (PRC2), formed a feedback circuit in which miR-144 targeted EZH2 and PRC2 epigenetically repressed the miRNA genes via histone H3K27 methylation of the promoter. The miRNA cluster was coordinately silenced by distal enhancer hypermethylation, disrupting chromatin loop formation and enhancer-promoter interactions. Clinical examinations indicated that methylation of this chromatin region is a potential HCC biomarker. CONCLUSIONS: Our study revealed novel mechanisms underlying miR-144/miR-451a cluster deregulation and the crosstalk between malignant cells and tumor-associated macrophages (TAMs) in HCC, providing new insights into HCC pathogenesis and diagnostic strategies.

INTRODUCTION: Current guidelines recommend anticoagulation as the mainstay of portal vein thrombosis (PVT) treatment in cirrhosis. However, because of the heterogeneity of PVT, anticoagulation alone does not always achieve satisfactory results. This study aimed to prospectively evaluate an individualized management algorithm using a wait-and-see strategy (i.e., no treatment), anticoagulation, and transjugular intrahepatic portosystemic shunt (TIPS) to treat PVT in cirrhosis. METHODS: Between February 2014 and June 2018, 396 consecutive patients with cirrhosis with nonmalignant PVT were prospectively included in a tertiary care center, of which 48 patients (12.1%) were untreated, 63 patients (15.9%) underwent anticoagulation, 88 patients (22.2%) underwent TIPS, and 197 patients (49.8%) received TIPS plus post-TIPS anticoagulation. The decision of treatment option mainly depends on the stage of liver disease (symptomatic portal hypertension or not) and degree and extension of thrombus. RESULTS: During a median 31.7 months of follow-up period, 312 patients (81.3%) achieved partial (n = 25) or complete (n = 287) recanalization, with 9 (3.1%) having rethrombosis, 64 patients (16.2%) developed major bleeding (anticoagulation-related bleeding in 7 [1.8%]), 88 patients (22.2%) developed overt hepatic encephalopathy, and 100 patients (25.3%) died. In multivariate competing risk regression models, TIPS and anticoagulation were associated with a higher probability of recanalization. Long-term anticoagulation using enoxaparin or rivaroxaban rather than warfarin was associated with a decreased risk of rethrombosis and an improved survival, without increasing the risk of bleeding. However, the presence of complete superior mesenteric vein thrombosis was associated with a lower recanalization rate, increased risk of major bleeding, and poor prognosis. DISCUSSION: In patients with cirrhosis with PVT, the individualized treatment algorithm achieves a high-probability recanalization, with low rates of portal hypertensive complications and adverse events.

OBJECTIVES: Patients with severe cirrhotic ascites have poor prognosis, yet individual patient survival varies greatly. Therefore, suitable prognostic models can be helpful in clinical decision making. The aim of this study was to evaluate and compare the performance of 10 scores in predicting transplant-free survival (TFS) after transjugular intrahepatic portosystemic shunt (TIPS) in severe cirrhotic ascites. METHODS: Two hundred eighty consecutive cirrhotic patients with severe ascites undergoing TIPS between March 2006 and December 2017 were retrospectively screened and included from nine tertiary Chinese centers, consisting of 123 patients with refractory ascites and 157 with recurrent ascites. Discriminatory ability of these models was further assessed in the whole cohort and subgroups. RESULTS: TFS rates of all 280 patients were 75.4, 65.7, and 53.6% at 6-month, 1-year, and 2-year follow-up, respectively. Compared with other prognostic systems, the integrated model for end-stage liver disease (iMELD, incorporating serum sodium and age) showed optimal performance in predicting 6-month, 1-year, and 2-year TFS. Cutoffs were determined according to c-index and were used to stratify patients into three strata presenting significantly different TFS for short-term and long-term: iMELD < 32, ≥32 but <38 and ≥38 (log-rank P < 0.001). CONCLUSIONS: The iMELD score proved to be the best prognostic model in predicting TFS in patients with severe cirrhotic ascites receiving TIPS. Meanwhile, the model could stratify patients in three strata to help guiding clinical practice.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic is a once-in-century crisis to public health. Although the pathogen for COVID-19, the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), has been identified, the pandemic is still ongoing. The critically ill COVID-19 patients account for most disease-associated death; thus, there is an urgent need to identify prognostic factors that would help determine therapeutic approaches. METHODS: In this study, we retrospectively analyzed the clinical and laboratory findings in 100 critically ill COVID-19 patients in Hubei Women & Children Healthcare Hospital (Guanggu District), of whom 22 patients died in hospital, and 78 patients survived. RESULTS: We found that age, lymphocyte count, and total bilirubin concentration were an independent prognostic factor for critically ill COVID-19 patients. Of particular importance, we observed a significant elevation of myocardium injury biomarkers, including CK-MB, high-sensitivity cardiac troponini I (hs-cTnI), and Mb, in the non-survivor group. These myocardium injury biomarkers appeared to correlate with the time of survival, and two multivariate models have suggested hs-cTnI was a novel prognostic factor with a sensitivity of 75.0% and a specificity of 84.9%. CONCLUSIONS: Altogether, our study highlighted the prognostic significance of myocardium injury biomarkers in critically ill COVID-19 patients. Monitoring myocardium injury biomarkers would predict patient survival and guide therapeutic strategy.

INTRODUCTION: The benefits of combining transarterial chemoembolization (TACE) and sorafenib (TACE-S) over TACE alone for treatment of unresectable hepatocellular carcinoma (HCC) remain controversial. Yet, such populations are heterogeneous in terms of baseline characteristics. OBJECTIVE: To investigate the predictors of survival benefits from added sorafenib and identify the potential candidates for TACE-S. METHODS: This multicenter observational study was conducted in 17 Chinese tertiary hospitals for patients with unresectable, liver-confined HCC. Eligible patients with performance status score of ≤1 and Child-Pugh score of ≤7 were treated with TACE or TACE-S. Interactions between treatment and baseline variables were evaluated to find indicators for survival benefits, based on which the patients were stratified. Multivariate models adjusted for baseline characteristics or propensity score were used to compare overall survival (OS) and time to tumor progression (TTP). RESULTS: From January 2009 to December 2015, 1,719 consecutive patients received TACE (n = 1,406) or TACE-S (n = 313). Although TACE-S compared with TACE improved TTP (adjusted hazard ratio [HR] 0.75, p = 0.008), no difference in OS was observed (adjusted HR 0.87, p = 0.090). Nevertheless, the tumor burden (sum of maximum diameter of largest tumor [cm] and tumor number) and albumin-bilirubin (ALBI) score independently predicted the survival benefits from added sorafenib (interaction p< 0.001). For patients with either moderate tumor burden (7-13) or low ALBI score (no more than -2.8) defined as candidates, TACE-S prolonged OS (adjusted HR 0.73, p = 0.003) and TTP (adjusted HR 0.72, p = 0.014) compared to TACE alone, whereas its superiority disappeared in non-candidates. CONCLUSIONS: Not all unresectable HCC patients but those with moderate tumor burden or low ALBI score achieve survival benefits from TACE-S compared with TACE alone. Future randomized controlled trials focusing on the subset are warranted.
RESUMEN
BACKGROUND: Albumin-Bilirubin (ALBI) grade has been proposed for the evaluation of liver function in hepatocellular carcinoma (HCC). The combination therapy of transarterial chemoembolization (TACE) and sorafenib is widely used for HCC patients with preserved liver function; our study aimed to investigate and compare the discriminating values of ALBI grade and Child-Pugh score in overall survival (OS). METHODS: A total of 173 HCC patients with preserved liver function (Child-Pugh A) were enrolled. The prognostic values of OS for ALBI grade and Child-Pugh score were separately investigated. RESULTS: In multivariate analyses, both ALBI grade and Child-Pugh score could significantly stratify the patients with different OS [adjusted hazard ratio (HR) 2.15 and 1.48, P<0.001 and P=0.035 for ALBI grade and Child-Pugh score]. In addition, time-dependent ROC analysis demonstrated that the ALBI grade had a better discriminatory ability than Child-Pugh score in predicting survival, especially for long-term outcomes. According to the subgroup analyses, the ALBI grade remained significant in more patient subsets and was more consistent than Child-Pugh score for the prediction of OS. CONCLUSIONS: ALBI grade was better than Child-Pugh score in stratifying prognosis for HCC patients with preserved liver function (Child-Pugh A) and treated by the combination therapy of TACE and sorafenib.
RESUMEN
BACKGROUND: Hepatocellular carcinoma (HCC) is a common cancer worldwide and prognosis for patients with the disease remains poor. Most patients are diagnosed at an advanced stage and are only eligible for palliative therapy. As a novel vascular endothelial growth factor receptor-2 tyrosine kinase inhibitor (VEGFR2-TKI), apatinib has a certain antitumor effect for a variety of solid tumors. In clinical practice, clinicians have attempted to treat intermediate- to advanced-stage HCC patients with a combination of transcatheter arterial chemoembolization (TACE) and apatinib. However, a consensus on the therapeutic effects of this treatment is yet to be reached. This meta-analysis was conducted to compare the therapeutic efficacy and clinical safety of the combination therapy of TACE plus apatinib with that of TACE alone in patients with intermediate- to advanced-stage HCC. METHODS: Relevant studies were identified by searching PubMed, Embase, Web of Science, the Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang Database, Chinese Biomedical Literature Database (CBM), Chinese Science and Technology Periodical Database (VIP) and the reference lists of retrieved articles up to July 31, 2019. Pooled odds ratios (OR) and 95% confidence intervals (CI) were calculated to express the therapeutic effects of TACE plus apatinib versus TACE on survival, objective response rate, disease control rate, progressive disease rate and adverse events using a mixed-effect model. Subgroup analyses of study type, dosage of apatinib, TACE regimen, study sample size between treatment groups and control groups were performed. Publication bias was assessed using fail-safe N, Begg-Mazumdar test and Egger's test. RESULTS: From 23 eligible studies, a total of 1,342 patients were included in this review and meta-analysis. Among these studies, 18 were randomized clinical trials and 5 were case-control studies. Compared with those being treated with TACE alone, patients receiving TACE plus apatinib showed significantly better half-year survival (OR, 2.741, 95% CI, 1.745-4.306) and 1-year survival (OR, 2.284, 95% CI, 1.442-3.620). The superiority of TACE and apatinib over TACE monotherapy was evident in the disease control rate (OR, 2.919, 95% CI, 2.184-3.903), objective response rate (OR, 2.683, 95% CI, 2.099-3.429) and progressive disease rate (OR, 0.341, 95% CI, 0.255-0.456), respectively. CONCLUSIONS: The combination treatment of apatinib and TACE provides better survival benefits for intermediate- to advanced-stage HCC patients when compared to TACE monotherapy and should be recommended for suitable patients with unresectable HCC. However, further investigation into future prospective clinical studies is warranted.
RESUMEN
BACKGROUND: Transarterial chemoembolization (TACE) is recommended for patients with intermediate hepatocellular carcinoma (HCC) according to treatment guidelines. However, a large number of patients with advanced HCC also receive TACE in clinical practice, especially for those with liver-confined HCC and Eastern Cooperative Oncology Group score (ECOG) 1. In view of previous studies, such patients have different prognoses from advanced HCC patients with macrovascular invasion or extrahepatic spread; therefore, patients with ECOG 1 alone might be classified into the intermediate stage and benefit from TACE treatment, but a study particularly focusing on such patients and exploring the effectiveness of TACE therapy is lacking. AIM: To investigate treatment outcomes of TACE in HCC patients with ECOG 1 alone and propose a specific prognostic model. METHODS: Patients from 24 Chinese tertiary hospitals were selected in this nationwide multicenter observational study from January 2010 to May 2016. Overall survival (OS) was estimated using Kaplan-Meier curves and compared by the log-rank test. Multivariate Cox regression was used to develop the potential prognostic models. The discriminatory ability of the models was compared and validated in various patient subgroups. The individual survival prediction for six-and-twelve (6&12) criteria, defined as the algebraic sum of tumor size (cm) and tumor number, was illustrated by contour plot of 3-year survival probability and nomogram. RESULTS: A total of 792 eligible patients were included. During follow-up, median OS reached 18.9 mo [95% confidence interval (CI): 16.9-21.0]. Three independent multivariate analyses demonstrated that tumor size, tumor number, α-fetoprotein level, albumin-bilirubin grade and total bilirubin were prognostic factors of OS (P < 0.05). The previously proposed 6&12 criteria was comparable or even better than currently proposed with the highest predictive ability. In addition, the 6&12 criteria was correlated with OS in various subgroups of patients. The patients were stratified into three strata with score ≤ 6, > 6 but ≤ 12, and > 12 with different median OS of 39.8 mo (95%CI: 23.9-55.7), 21.1 mo (95%CI: 18.4-23.8) and 9.8 mo (95%CI: 8.3-11.3), respectively (P < 0.001). CONCLUSION: TACE is effective for advanced HCC patients with ECOG 1 alone, and the 6&12 criteria may help with clinical decision-making.

BACKGROUND: The treatment outcome of transarterial chemoembolization (TACE) in unresectable hepatocellular carcinoma (HCC) varies greatly due to the clinical heterogeneity of the patients. Therefore, several prognostic systems have been proposed for risk stratification and candidate identification for first TACE and repeated TACE (re-TACE). AIM: To investigate the correlations between prognostic systems and radiological response, compare the predictive abilities, and integrate them in sequence for outcome prediction. METHODS: This nationwide multicenter retrospective cohort consisted of 1107 unresectable HCC patients in 15 Chinese tertiary hospitals from January 2010 to May 2016. The Hepatoma Arterial-embolization Prognostic (HAP) score system and its modified versions (mHAP, mHAP2 and mHAP3), as well as the six-and-twelve criteria were compared in terms of their correlations with radiological response and overall survival (OS) prediction for first TACE. The same analyses were conducted in 912 patients receiving re-TACE to evaluate the ART (assessment for re-treatment with TACE) and ABCR (alpha-fetoprotein, Barcelona Clinic Liver Cancer, Child-Pugh and Response) systems for post re-TACE survival (PRTS). RESULTS: All the prognostic systems were correlated with radiological response achieved by first TACE, and the six-and-twelve criteria exhibited the highest correlation (Spearman R = 0.39, P = 0.026) and consistency (Kappa = 0.14, P = 0.019), with optimal performance by area under the receiver operating characteristic curve of 0.71 [95% confidence interval (CI): 0.68-0.74]. With regard to the prediction of OS, the mHAP3 system identified patients with a favorable outcome with the highest concordance (C)-index of 0.60 (95%CI: 0.57-0.62) and the best area under the receiver operating characteristic curve at any time point during follow-up; whereas, PRTS was well-predicted by the ABCR system with a C-index of 0.61 (95%CI: 0.59-0.63), rather than ART. Finally, combining the mHAP3 and ABCR systems identified candidates suitable for TACE with an improved median PRTS of 36.6 mo, compared with non-candidates with a median PRTS of 20.0 mo (log-rank test P < 0.001). CONCLUSION: Radiological response to TACE is closely associated with tumor burden, but superior prognostic prediction could be achieved with the combination of mHAP3 and ABCR in patients with unresectable liver-confined HCC.

BACKGROUND: The global outbreak of COVID-19 is a significant threat to public health. Among COVID-19 cases, critically ill patients account for most in-hospital deaths. Given the pressing clinical needs, identification of potential prognostic factors that would assist clinicians to determine appropriate therapeutic interventions is urgently needed. METHODS: A retrospective analysis of 171 critically ill COVID-19 patients from two medical centers in Wuhan was conducted. The training and validation cohorts were comprised of 77 and 94 patients, respectively. Univariate and multivariate Logistic regression analyses were used to identify independent prognostic factors, and the linear prediction index was established and externally validated. RESULTS: Blood urine nitrogen (BUN) and high-sensitive C-reactive protein (hs-CRP) were independent factors negatively correlated with patient survival in the training cohort. A linear prediction model, named as the CB index (hs-CRP combined with BUN), was established and logistic regression analysis showed that this was associated with a 13% increase in death rate, with high sensitivity (86.7%) and specificity (89.7%). Patients were then divided into a high-risk group (CB index >32) and low-risk group (CB index <32) and the high-risk group showed a 56.3-fold risk of death compared with the low-risk group. Importantly, these findings were readily recaptured in the validation cohort. The efficacy of the CB index in predicting prognosis in real-world patients was then determined, which showed that patients with a higher CB index had an increased risk of death in comparison to those with a lower CB index. CONCLUSIONS: The CB index may be an important prognostic factor in critically ill COVID-19 patients.
RESUMEN
Dysfunction of natural killer (NK) cells is associated with poor prognosis in hepatocellular carcinoma (HCC). We explored the phenotypic and functional characteristics of peripheral blood NK cells in HCC patients following sorafenib treatment.Peripheral blood samples were collected from 60 HCC patients in a single centre (2015~2017) and 45 healthy donors. The percentage and cytoplasmic granule production of NK cells were analysed. Subset proportions were evaluated for their associations with the modified Response Evaluation Criteria in Solid Tumors (mRECIST), time to progression, and median overall survival (OS).Compared with baseline, the percentages of total and CD56dimCD16+ NK cells increased after two months of treatment, while the percentage of CD56brightCD16- NK cells decreased, leading to a dramatically reduced ratio of CD56bright and CD56dim NK cells (ratiobri/dim). Patients with low ratiobri/dim exhibited better mRECIST responses and longer median OS than those with high ratiobri/dim. The expression levels of granzyme B and perforin in total NK cells and in both subsets of cells were increased after treatment.This study showed that sorafenib could affect the proportions and functions of peripheral CD56brightCD16- and CD56dimCD16+ NK cells, which was associated with the outcomes including OS of HCC patients.

Background: Combination therapy of transarterial chemoembolization plus sorafenib (TACE-S) has been proven to be safe and effective for hepatocellular carcinoma (HCC); however, this combination therapy is associated with a high incidence of adverse events (AEs). Our study focused on the relationships between AEs and treatment outcomes and aimed to discover AE-based clinical markers that can predict the survival benefits of combination treatment. Methods: From January 2010 to June 2014, a total of 235 HCC patients treated with TACE-S were retrospectively enrolled. Major sorafenib-related AEs were prospectively recorded, and their correlations with overall survival (OS) were analysed using time-dependent covariate Cox regression analyses. Results: The majority of the patients (200, 85.1%) were male, and the median age was 51 years old. After two years of follow-up, the median OS of the study population reached 12.4 months. In all, 218 patients (92.8%) presented at least one AE, and 174 (74.0%) suffered AEs ≥2 grade. Based on time-dependent multivariate analyses, the development of hand-foot skin reaction (HFSR) ≥2 grade (HR = 0.43, 95% CI: 0.32-0.58, P < 0.001) and diarrhoea ≥1 grade (HR = 0.72, 95% CI: 0.53-0.97, P=0.029) were identified as independent predictors of prolonged OS. Moreover, patients who developed both HFSR ≥2 grade and diarrhoea ≥1 grade achieved better outcomes than those patients who developed either or neither of these AEs (HR = 1.51, 95% CI: 1.11-2.06, P=0.009). Conclusions: The development of HFSR ≥2 grade or diarrhoea ≥1 grade during TACE-S treatment indicated prolonged OS, and these AEs should be considered important clinical markers for predicting patient prognoses.
