Transarterial Chemoembolization with Epirubicin-Loaded Microspheres for Hepatocellular Carcinoma: A Prospective, Single-Arm, Multicenter, Phase 2 Study (STOPPER Trial).

PURPOSE: While the role of drug-eluting beads transarterial chemoembolization (DEB-TACE) for hepatocellular carcinoma (HCC) is established, questions regarding appropriate bead size for use in patients remain. This trial evaluated the effectiveness and safety of DEB-TACE using small-size (≤ 100 µm) microspheres loaded with epirubicin. MATERIALS AND METHODS: This prospective, single-arm, multicenter study enrolled patients diagnosed with HCC who underwent DEB-TACE using 40 (range, 30-50), 75 (range, 60-90), or 100 (range, 75-125) µm epirubicin-loaded microspheres (TANDEM microspheres, Varian Medical). Bead size was at the discretion of treating physicians and based on tumor size and/or vascular structure. The primary outcome measure was 6-month objective response rate (ORR). Secondary outcome measures were 30-day and 3-month ORR, time to tumor progression and extrahepatic spread, proportion of progression-free survival and overall survival (OS) at one year, and incidence of treatment-associated adverse events. RESULTS: Data from 108 patients from ten centers was analyzed. Six-month ORR was 73.3 and 71.3% based on European association for the study of the liver (EASL) and modified response evaluation criteria in solid tumors (mRECIST) criteria, respectively. Thirty-day ORR was 79.6% for both EASL and mRECIST criteria with 3-month ORR being 80.0 and 81.0%, respectively, for each criteria. One-year PPF and OS rate were 60.3 and 94.3%. There was a total of 30 SAEs reported to be likely to definitely associated with microsphere (n = 9), epirubicin (n = 9), or procedure (n = 12) with none resulting in death. CONCLUSION: DEB-TACE using epirubicin-loaded small-sized (≤ 100 µm) microspheres demonstrates promising local tumor control and acceptable safety in patients with HCC.

Arterial chemotherapy for hepatocellular carcinoma in China: consensus recommendations.

Hepatocellular carcinoma (HCC) is one of the most common malignancies and the third leading cause of cancer-related deaths globally. Hepatic arterial infusion chemotherapy (HAIC) treatment is widely accepted as one of the alternative therapeutic modalities for HCC owing to its local control effect and low systemic toxicity. Nevertheless, although accumulating high-quality evidence has displayed the superior survival advantages of HAIC of oxaliplatin, fluorouracil, and leucovorin (HAIC-FOLFOX) compared with standard first-line treatment in different scenarios, the lack of standardization for HAIC procedure and remained controversy limited the proper and safe performance of HAIC treatment in HCC. Therefore, an expert consensus conference was held on March 2023 in Guangzhou, China to review current practices regarding HAIC treatment in patients with HCC and develop widely accepted statements and recommendations. In this article, the latest evidence of HAIC was systematically summarized and the final 22 expert recommendations were proposed, which incorporate the assessment of candidates for HAIC treatment, procedural technique details, therapeutic outcomes, the HAIC-related complications and corresponding treatments, and therapeutic scheme management.

OBJECTIVES: To investigate the therapeutic effect of recombinant human growth hormone (rhGH) on children with growth hormone deficiency (GHD) and different pituitary developmental conditions. METHODS: A prospective study was performed on 90 children with GHD who were admitted to Xuchang Maternity and Child Health Hospital from June 2020 to December 2021. According to pituitary height on the median sagittal plane, they were divided into three groups: pituitary dysplasia group (n=45), normal pituitary group (n=31), and enlarged pituitary growth group (n=14). The changes in body height, growth velocity, height standard deviation score and serum levels of insulin-like growth factor binding protein-3 (IGFBP-3) and insulin-like growth factor-1 (IGF-1) were examined after treatment in the above three groups, and the differences of the above indices before and after treatment were compared among the three groups. RESULTS: After treatment, all three groups had significant increases in body height, growth velocity, height standard deviation score, and the serum levels of IGFBP-3 and IGF-1 (P<0.05). Compared with the normal pituitary group, the pituitary dysplasia group and the enlarged pituitary growth group had significantly higher values in terms of the differences in body height, growth velocity, height standard deviation score, IGF-1, and IGFBP-3 before and after treatment (P<0.05). There was no significant difference in the incidence rate of adverse reactions among the three groups (P>0.05). CONCLUSIONS: In GHD children with different pituitary developmental conditions, rhGH can promote bone growth and increase body height, especially in children with pituitary dysplasia and pituitary hyperplasia, with good safety.

Combined iodine-125 seed strand, portal vein stent, transarterial chemoembolization, lenvatinib and anti-PD-1 antibodies therapy for hepatocellular carcinoma and Vp4 portal vein tumor thrombus: A propensity-score analysis.

Objective: To evaluate the safety and efficacy of interventional therapy (iodine-125[125I] seed strand and portal vein stent [PVS] implantation plus transarterial chemoembolization [TACE]) combined with systemic therapy (lenvatinib plus anti-PD-1 antibody) as first-line treatment for hepatocellular carcinoma (HCC) patients with Vp4 portal vein tumor thrombus (PVTT). Patients and methods: From December 2018 to October 2021, 87 HCC patients with Vp4 PVTT were included in this single-center retrospective study. Forty-seven patients underwent interventional therapy combined with lenvatinib and anti-PD-1 antibody (group A), while 40 cases underwent interventional therapy combined with lenvatinib only (group B). Overall response rate (ORR), stent occlusion rates (SOR), median overall survival (OS), median progression-free survival (PFS) and median stent patency time (SPT) were compared between the 2 groups. Results: The mean intended dose (r = 10 mm; z = 0; 240 days) was 64.9 ± 1.0 Gy and 64.5 ± 1.1 Gy in group A and B, respectively (p = 0.133). ORR and SOR were significantly different between group A and B (ORR, 55.3% vs 17.5%, p < 0.001; SOR, 12.8% vs 35.0%, p = 0.014). In the propensity-score matching (PSM) cohort, the median OS, median PFS and median SPT were significantly longer in group A compared with group B (32 PSM pairs; OS, 17.7 ± 1.7 vs 12.0 ± 0.8 months, p = 0.010; PFS, 17.0 ± 4.3 vs 8.0 ± 0.7 months, p < 0.001; SPT, not-reached vs 12.5 ± 1.1 months, p = 0.028). Conclusion: This interventional therapy combined with lenvatinib and anti-PD-1 antibody is safe and effective for HCC patients with Vp4 PVTT.

Regulator of G-protein signaling 14 protects the liver from ischemia-reperfusion injury by suppressing TGF-ß-activated kinase 1 activation.

BACKGROUND AND AIMS: Hepatic ischemia-reperfusion injury (IRI) is a common complication of hepatectomy and liver transplantation. However, the mechanisms underlying hepatic IRI have not been fully elucidated. Regulator of G-protein signaling 14 (RGS14) is a multifunctional scaffolding protein that integrates the G-protein and mitogen-activated protein kinase (MAPK) signaling pathways. However, the role of RGS14 in hepatic IRI remains unclear. APPROACH AND RESULTS: We found that RGS14 expression increased in mice subjected to hepatic ischemia-reperfusion (IR) surgery and during hypoxia reoxygenation in hepatocytes. We constructed global RGS14 knockout (RGS14-KO) and hepatocyte-specific RGS14 transgenic (RGS14-TG) mice to establish 70% hepatic IRI models. Histological hematoxylin and eosin staining, levels of alanine aminotransferase and aspartate aminotransferase, expression of inflammatory factors, and apoptosis were used to assess liver damage and function in these models. We found that RGS14 deficiency significantly aggravated IR-induced liver injury and activated hepatic inflammatory responses and apoptosis in vivo and in vitro. Conversely, RGS14 overexpression exerted the opposite effect of the RGS14-deficient models. Phosphorylation of TGF-ß-activated kinase 1 (TAK1) and its downstream effectors c-Jun N-terminal kinase (JNK) and p38 increased in the liver tissues of RGS14-KO mice but was repressed in those of RGS14-TG mice. Furthermore, inhibition of TAK1 phosphorylation rescued the effect of RGS14 deficiency on JNK and p38 activation, thus blocking the inflammatory responses and apoptosis. CONCLUSIONS: RGS14 plays a protective role in hepatic IR by inhibiting activation of the TAK1-JNK/p38 signaling pathway. This may be a potential therapeutic strategy for reducing incidences of hepatic IRI in the future.

Random Survival Forests to Predict Disease Control for Hepatocellular Carcinoma Treated With Transarterial Chemoembolization Combined With Sorafenib.

Objectives: To use baseline variables to predict one-year disease control for patients with hepatocellular carcinoma (HCC) treated with transarterial chemoembolization (TACE) combined with sorafenib as initial treatment by applying a machine learning approach based on the random survival forest (RF) model. Materials and Methods: The multicenter retrospective study included 496 patients with HCC treated with TACE combined with sorafenib between January 2014 and December 2018. The independent risk factors associated with one-year disease control (complete response, partial response, stable disease) were identified using the RF model, and their predictive importance was determined using the Gini index. Tumor response was assessed according to modified Response Evaluation Criteria in Solid Tumors. Results: The median overall survival was 15.5 months. A total of 186 (37.5%) patients achieved positive one-year disease control. The Barcelona Clinic Liver Cancer (BCLC) stage (Gini index: 20.0), tumor size (≤7 cm, >7 cm; Gini index: 9.0), number of lobes involved (unilobar, bilobar; Gini index: 6.4), alpha-fetoprotein level (≤200 ng/dl, >200 ng/dl; Gini index: 6.1), albumin-bilirubin grade (Gini index: 5.7), and number of lesions (1, >1; Gini index: 5.3) were identified as independent risk factors, with the BCLC stage as the most important variable. The RF model achieved a higher concordance index of 0.724 compared to that for the logistic regression model (0.709). Conclusions: The RF model is a simple and accurate approach for prediction of one-year disease control for patients with HCC treated with TACE combined with sorafenib.

Neutrophil-to-Lymphocyte and Platelet-to-Lymphocyte Ratios as Predictors of Outcomes in Patients With Unresectable Hepatocellular Carcinoma Undergoing Transarterial Chemoembolization Plus Sorafenib.

Objectives: To investigate the predictive value of inflammatory biomarkers in patients with unresectable hepatocellular carcinoma (HCC) for outcomes following the combination treatment of transarterial chemoembolization (TACE) plus sorafenib. Materials and Methods: A total of 314 (270 male and 44 female) treatment-naïve patients with unresectable HCC treated by TACE plus sorafenib between January 2011 and December 2018 were enrolled in the retrospective study. The primary outcome was overall survival (OS). The secondary outcome was progression-free survival (PFS). Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were obtained within 3-7 days before the initial TACE and the median value of the NLR and PLR was considered as the cut-off value. Results: The median value of NLR and PLR was 2.42 and 100, respectively. The median OS and PFS of the entire cohort were 18.7 months (95% CI: 16.8-20.6) and 9.1 months (95% CI: 8.5-9.8), respectively. The low NLR and PLR group showed improved OS and PFS compared with the high NLR and PLR group [21.8 months (95% CI: 15.2-28.5) vs. 15.4 months (95% CI: 12.4-18.3), p < 0.0001; 21.6 months (95% CI: 15.8-27.5) vs. 14.9 months (95% CI: 11.9-17.8), p = 0.00027, respectively]. In addition, the low NLR and PLR group also provided a longer PFS than the high NLR and PLR group [10.4 months (95% CI: 8.9-12.0) vs. 8.1 months (95% CI: 7.1-9.2), p = 0.00022; 10.3 months (95% CI: 8.6-11.9) vs. 8.2 months (95% CI: 7.2-9.2), p < 0.0001, respectively]. High NLR and PLR at baseline were predictive factors of poor OS (p = 0.02 and p = 0.004) and PFS (p = 0.045 and p = 0.005). Conclusion: This study showed the prognostic value of quantitative inflammatory biomarkers in correlation with OS and PFS in unresectable HCC patients undergoing TACE plus sorafenib treatment.

Embolization of the Transhepatic Tract after Percutaneous Portal Vein Interventions: Single-Centre Retrospective Study Comparing n-butyl Cyanoacrylate Versus Coils.

PURPOSE: The aim of this study was to compare the safety and efficacy of transhepatic puncture tract embolization with n-butyl cyanoacrylate (n-BCA) versus coils after percutaneous transhepatic portal vein interventions in patients with hepatocellular carcinoma (HCC). It was also the aim of the study to evaluate the extent of artifacts in CT exams during FU. METHODS: Single-center retrospective study from 2017-2019 in 190 patients who underwent percutaneous transhepatic portal vein interventions. The transhepatic puncture tracts were embolized with n-BCA in 88 patients (Group A) and with coils in 102 patients (Group B). Procedure-related complications and image noise around coils and n-BCA were compared between the groups. No significant differences were noted at baseline between both groups (platelets, coagulation, liver disease, types of procedures, liver function, liver tumors). RESULTS: All patients underwent transhepatic puncture tract embolization. Procedure-related complications were only observed in patients from Group B: subcapsular hemorrhage (n = 2; 1.96%), hepatic artery hemorrhage (n = 1; 0.98%), and pseudoaneurysms combined with hemobilia occurred (n = 1; 0.98%). In Group A, the distal part of the punctured portal vein branch was embolized with n-BCA in 1 patient (1.14%). Four major complications in Group B Vs 0 in Group A were observed, respectively (p < 0.0001). The image noise around n-BCA was significantly lower than that around coils (10.7 ± 1.7 HU vs. 54.3 ± 15.0 HU, p < .001). CONCLUSIONS: n-BCA tract embolization is more effective than using coils, with fewer bleeding events, at the cost of a higher potential for unintended embolization of portal vein branches.

Prognosis Nomogram for Hepatocellular Carcinoma Patients with Portal Vein Invasion Undergoing Transarterial Chemoembolization Plus Sorafenib Treatment: A Retrospective Multicentre Study.

OBJECTIVES: To explore the outcomes of combined transarterial chemoembolization (TACE) with sorafenib in hepatocellular carcinoma (HCC) patients with portal vein tumour thrombus (PVTT) and to establish a prognostic prediction nomogram to differentiate target patients and stratify risk. MATERIALS AND METHODS: This multicentre, retrospective study consisted of 185 consecutive treatment-naïve patients with HCC and PVTT treated with TACE plus sorafenib from three institutions between January 1st, 2012 and December 31st, 2017. The primary outcome measurement of the study was overall survival (OS). The type of PVTT was classified by the Liver Cancer Study Group of Japan. The prognostic nomogram was established based on the predictors and was performed with interval validation. RESULTS: The median OS of the Vp1-3 and Vp4 groups was 12.4 months (11.7-18.9) and 8.5 months (7.6-11.2) (P = 0.00098), respectively, and there was a significant difference in the median OS between the Vp1-2 and Vp3 subgroups (16.4 months (12.2-27.9) vs. 10.9 months (8.4-18.1), P = 0.041). The multivariate Cox regression analysis suggested that tumour size, albumin-bilirubin grade, and PVTT type were independent prognostic factors. The C-index value of the nomogram based on these predictors in the entire cohort was 0.731 (0.628-0.833). CONCLUSIONS: After the combined therapy of TACE and sorafenib, advanced HCC patients with segmental or subsegmental PVTT showed better survival than those with main PVTT. The nomogram can be applied to identify advanced HCC patients with PVTT who may benefit most from the combination treatment and be helpful for making decision in clinical practice.

Deep Learning Predicts Overall Survival of Patients With Unresectable Hepatocellular Carcinoma Treated by Transarterial Chemoembolization Plus Sorafenib.

OBJECTIVES: To develop and validate a deep learning-based overall survival (OS) prediction model in patients with hepatocellular carcinoma (HCC) treated with transarterial chemoembolization (TACE) plus sorafenib. METHODS: This retrospective multicenter study consisted of 201 patients with treatment-naïve, unresectable HCC who were treated with TACE plus sorafenib. Data from 120 patients were used as the training set for model development. A deep learning signature was constructed using the deep image features from preoperative contrast-enhanced computed tomography images. An integrated nomogram was built using Cox regression by combining the deep learning signature and clinical features. The deep learning signature and nomograms were also externally validated in an independent validation set of 81 patients. C-index was used to evaluate the performance of OS prediction. RESULTS: The median OS of the entire set was 19.2 months and no significant difference was found between the training and validation cohort (18.6 months vs. 19.5 months, P = 0.45). The deep learning signature achieved good prediction performance with a C-index of 0.717 in the training set and 0.714 in the validation set. The integrated nomogram showed significantly better prediction performance than the clinical nomogram in the training set (0.739 vs. 0.664, P = 0.002) and validation set (0.730 vs. 0.679, P = 0.023). CONCLUSION: The deep learning signature provided significant added value to clinical features in the development of an integrated nomogram which may act as a potential tool for individual prognosis prediction and identifying HCC patients who may benefit from the combination therapy of TACE plus sorafenib.

Prognostic Performance of Albumin-Bilirubin Grade With Artificial Intelligence for Hepatocellular Carcinoma Treated With Transarterial Chemoembolization Combined With Sorafenib.

PURPOSE: To establish albumin-bilirubin (ALBI) grade-based and Child-Turcotte-Pugh (CTP) grade-based nomograms, as well as to develop an artificial neural network (ANN) model to compare the prognostic performance and discrimination of these two grades for hepatocellular carcinoma (HCC) treated with transarterial chemoembolization (TACE) combined with sorafenib as an initial treatment. METHODS: This multicenter retrospective study included patients from three hospitals between January 2013 and August 2018. In the training cohort, independent risk factors associated with overall survival (OS) were identified by univariate and multivariate analyses. The nomograms and ANN were established and then validated in two validation cohorts. RESULTS: A total of 504 patients (319, 61, and 124 patients from hospitals A, B, and C, respectively) were included. The median OS was 15.2, 26.9, and 14.8 months in the training cohort and validation cohorts 1 and 2, respectively (P = 0.218). In the training cohort, both ALBI grade and CTP grade were identified as independent risk factors. The ALBI grade-based and CTP grade-based nomograms were established separately and showed similar prognostic performance and discrimination when validated in the validation cohorts (C-index in validation cohort 1: 0.799 vs. 0.779, P = 0.762; in validation cohort 2: 0.700 vs. 0.693, P = 0.803). The ANN model showed that the ALBI grade had higher importance in survival prediction than the CTP grade. CONCLUSIONS: The ALBI grade and CTP grade have comparable prognostic performance for HCC patients treated with TACE combined with sorafenib. ALBI grades 1 and 2 have the potential to act as a stratification factor for clinical trials on the combination therapy of TACE and systemic therapy.

Transradial access chemoembolization for hepatocellular carcinoma in comparation with transfemoral access.

BACKGROUND: This study aimed to compare the safety and efficacy of transradial access (TRA) with transfemoral access (TFA) chemoembolization in treatment of hepatocellular carcinoma (HCC). METHODS: HCC patients who were late for curative treatment on initial diagnosis or HCC patients who had undergone one or several rounds of transarterial chemoembolization (TACE) were enrolled. The clinical and angiographic characteristics, the procedure related details, and the follow-up data from patients who underwent TRA and TFA were analyzed and compared. RESULTS: In total, 112 patients undergoing 160 TRA-TACE and 107 patients undergoing 163 TFA-TACE were included. The technical success rate of TRA was 95.0% and that of TFA was 98.8% (P=0.102). In the TFA-TACE group, 5.5% of cases suffered access site-related complications, including 6 with minor bleeding and 3 with severe bleeding or pseudoaneurysm. In the TRA-TACE group, 1.9% of cases underwent crossover to femoral access for selective cannulation failure. The rate of radial artery occlusion (RAO) was 2.7% (3 of 112 patients), and none of the RAO patients suffered paresthesia, pain at the site of occlusion, hand function loss or distal ischemia. Comparing patients with/without access site-related complications in the TFA-TACE group, there was a statistical difference in patient age and in the percentage of patient with a PT time >15 s (72.6% vs. 57.1%, P<0.001; 44.4% vs. 11.7%, P=0.022). CONCLUSIONS: TRA is a safe and effective method for patients undergoing TACE. Compared with TFA, TRA may reduce the occurrence of access site-related bleeding and vascular complications. TRA-TACE may especially benefit older patients or those with a longer prothrombin time (PT).

Radiofrequency Ablation Combined With Transarterial Chemoembolization for Specially Located Small Hepatocellular Carcinoma.

OBJECTIVE: To investigate the safety and efficacy of radiofrequency ablation combined with transarterial chemoembolization in patients with specially located small hepatocellular carcinoma. MATERIALS AND METHODS: Between March 2014 and March 2017, a total of 26 patients with 26 lesions (10 perivascular, 6 subdiaphragmatic, 5 subcapsular, 5 perivascular, and subdiaphragmatic location; mean diameter 2.12 (0.62) cm), who received radiofrequency ablation-transarterial chemoembolization treatment, were retrospectively analyzed. Local tumor response was assessed by computed tomography/magnetic resonance imaging 1 month after the procedure. Tumor-free survival was also assessed according to the modified Response Evaluation Criteria in Solid Tumors. Complications were evaluated according to the National Cancer Institute's Common Terminology Criteria for Adverse Events (version 4.0). RESULTS: Complete response was achieved in all patients 1 month after the procedure. During a median follow-up duration of 16.76 months (95% confidence interval: 7.78-25.73 months), local tumor recurrence occurred in 2 patients and new intrahepatic lesions developed in 7 patients. The 1-, 2-, and 3-year cumulative local tumor progression rates were 3.84%, 7.69%, and 7.69%, respectively. The median tumor-free survival duration was 21.96 months (95% confidence interval: 17.58-26.34 months). The 1-, 2-, and 3-year tumor-free survival rates were 67.4%, 46.1%, and 39.3%, respectively. CONCLUSION: The radiofrequency ablation-transarterial chemoembolization combination therapy appears to be safe and effective and might be a treatment option for specially located small hepatocellular carcinoma lesions that have a risk of incomplete ablation or major complications.

Treatment of Hepatocellular Carcinoma with Tumor Thrombus with the Use of Iodine-125 Seed Strand Implantation and Transarterial Chemoembolization: A Propensity-Score Analysis.

PURPOSE: To evaluate the safety and efficacy of iodine-125 (125I) seed strand implantation in combination with transarterial chemoembolization for the treatment of hepatitis B-related unresectable hepatocellular carcinoma (HCC) with portal vein invasion. MATERIALS AND METHODS: From January 2013 to June 2016, 76 HCC patients with type II tumor thrombus were included in this single-center retrospective study. Twenty patients underwent 125I seed strand implantation combined with transarterial chemoembolization (group A; n = 20), while 56 patients underwent transarterial chemoembolization alone (group B; n = 56). The procedure-related and radiation complications were assessed. Overall survivals were compared by propensity-score analysis. RESULTS: The technique was successfully performed in all patients. The mean intended dose (r = 10 mm; z = 0; 240 days) was 62.6 ± 1.8 Gy. No grade 3 or 4 adverse events related to the procedure occurred in either group. After propensity-score-matching analysis, 19 patients were selected into each group, respectively. In the propensity-matching cohort, the median overall survival time was significantly longer in group A than in the group B (19 pairs; 28.0 ± 2.4 vs 8.7 ± 0.4 mo; P = .001). Treatment strategy, arterioportal shunt, and number of transarterial chemoembolization sessions were significant predictors of favorable overall survival time. CONCLUSIONS: 125I seed strand implantation combined with transarterial chemoembolization is a safe and effective treatment for HCC patients with portal vein invasion.

Combined endovascular brachytherapy, sorafenib, and transarterial chemobolization therapy for hepatocellular carcinoma patients with portal vein tumor thrombus.

AIM: To evaluate the safety and efficacy of combined endovascular brachytherapy (EVBT), transarterial chemoembolization (TACE), and sorafenib to treat hepatocellular carcinoma (HCC) patients with main portal vein tumor thrombus (MPVTT). METHODS: This single-center retrospective study involved 68 patients with unresectable HCC or those who were unfit for liver transplantation and percutaneous frequency ablation according to the BCLC classification. All patients had Child-Pugh classification grade A or B, Eastern Cooperative Oncology Group (ECOG) performance status of 0-2, and MPVTT. The patients received either EVBT with stent placement, TACE, and sorafenib (group A, n = 37), or TACE with sorafenib (group B, n = 31). The time to progression (TTP) and overall survival (OS) were evaluated by propensity score analysis. RESULTS: In the entire cohort, the 6-, 12-, and 24-mo survival rates were 88.9%, 54.3%, and 14.1% in group A, and 45.8%, 0%, and 0% in group B, respectively (P < 0.001). The median TTP and OS were significantly longer in group A than group B (TTP: 9.0 mo vs 3.4 mo, P < 0.001; OS: 12.3 mo vs 5.2 mo, P < 0.001). In the propensity score-matched cohort, the median OS was longer in group A than in group B (10.3 mo vs 6.0 mo, P < 0.001). Similarly, the median TTP was longer in group A than in group B (9.0 mo vs 3.4 mo, P < 0.001). Multivariate Cox analysis revealed that the EVBT combined with stent placement, TACE, and sorafenib strategy was an independent predictor of favorable OS (HR = 0.18, P < 0.001). CONCLUSION: EVBT combined with stent placement, TACE, and sorafenib might be a safe and effective palliative treatment option for MPVTT.

Nomogram for individualized prediction of recurrence after postoperative adjuvant TACE for hepatitis B virus-related hepatocellular carcinoma.

This study sought to develop an effective and reliable nomogram for predictions of recurrence for postoperative adjuvant transarterial chemoembolization (PA-TACE) in patients with hepatitis B virus-related (HBV) hepatocellular carcinoma (HCC).The nomogram was established based on data obtained from a retrospective study on 235 consecutive patients with HBV HCC who received PA-TACE as an initial therapy from 2006 to 2010 in our center. Eighty-four patients who were collected at another institution between 01/2008 and 12/2010 served as an external validation set. Recurrence-free survival (RFS) was collected. The nomogram for tumor recurrence was developed based on the data obtained before the PA-TACE procedure. Predictive accuracy and discriminative ability of the nomogram were assessed by concordance index (C-index), calibration curves, and validation set.The 1, 2, 3-year RFS rates were 55.5%, 27.0%, and 14.1%, respectively, in the patients from the derivation set and 60.7%, 33.2%, and 23.8% in those from the validation set. Four risk factors (HBV-DNA level, vascular invasion, change of Child-Pugh score, and tumor diameter) in the multivariate analysis were significantly associated with RFS. The statistical nomogram incorporated these 4 factors achieved good calibration and discriminatory abilities with the c-index of 0.74 (95% CI 0.66-0.82). The findings were supported by the independent external validation set (c-index, 0.70; 95% CI 0.58-0.83). The area under the receiver operating characteristic curve in our model was greater than those of conventional staging systems in the validation patients (corresponding c-indices, 0.56-0.64).The novel nomogram may achieve an optimal prediction for recurrence outcome in HBV-related HCC with PA-TACE.

Endovascular brachytherapy combined with portal vein stenting and transarterial chemoembolization improves overall survival of hepatocellular carcinoma patients with main portal vein tumor thrombus.

Hepatocellular carcinoma (HCC) patients with main portal vein tumor thrombus have a median survival time of only about 4 months. We therefore compared the safety and efficacy of endovascular brachytherapy (EVBT) and sequential three-dimensional conformal radiotherapy (3-DCRT). From a cohort of 176 patients, we treated 123 with EVBT using iodine-125 seed strands (group A) and the remaining 53 with sequential 3-DCRT (group B). Overall survival, progression free survival and stent patency characteristics were compared between the two groups. Our analysis demonstrated a median survival of 11.7 ± 1.2 months in group A versus 9.5 ± 1.8 months in group B (p = 0.002). The median progression free survival was 5.3 ± 0.7 months in groupA versus 4.4 ± 0.4 months in group B (p = 0.010). The median stent patency period was 10.3 ± 1.1 months in group A versus 8.7 ± 0.7 months in group B (p = 0.003). Therefore, as compared to sequential 3-DCRT, EVBT combined with portal vein stenting and TACE improved overall survival of HCC patients with main portal vein tumor thrombus.

Postsurgical treatment with adjuvant transarterial chemoembolization in patients with hepatitis B-related hepatocellular carcinoma: A strobe-compliant article.

This study sought to develop a reliable and easy-to-use scoring model to guide the decision to perform postsurgical adjuvant transarterial chemoembolization (PA-TACE) in patients with hepatitis B-related hepatocellular carcinoma (HCC).The study included 235 consecutive patients with hepatitis B-related HCC undergoing PA-TACE at our medical center. Patients were assigned to 2 sets according to the PA-TACE date: initial (2005-2007; n = 130) and internal validation (2008-2009; n = 105) sets. With the aid of a Cox regression model, we developed a risk-scoring model from the independent predictive factors of our initial set designed as a guide for PA-TACE, and the performance of the model was validated with an internal set. External validation was also performed with an independent dataset (n = 84) to assess the discriminatory power of the scoring model.In the multivariate analysis, 4 risk factors (an increase in Child-Pugh score of at least 1 point, hepatitis B virus deoxyribonucleic acid [HBV-DNA] level >10 IU/mL, tumor diameter ≥5 cm, and the presence of vascular invasion) were significantly associated with prognosis. These factors were incorporated into a novel clinicopathological scoring model (assessment for PA-TACE [APT] risk-scoring model) ranging from 0 to 8 that was correlated with prognosis. Different survival outcomes were identified in three groups (0-2 points, 3-6 points, and 7-8 points). The risk-scoring model was further confirmed with 2 independent sets.The novel APT risk-scoring model, merging 4 prognostic factors, may achieve an optimal postsurgical prediction of PA-TACE in HBV-related HCC. The risk for an individual patient with an APT score of ≥7.0 prior to the PA-TACE, who may not profit from further PA-TACE, can be determined, and this may lead to a more appropriate choice of treatment.

Prognostic nomogram for post-surgical treatment with adjuvant TACE in hepatitis B virus-related hepatocellular carcinoma.

OBJECTIVE: This study sought to establish an effective and reliable prognostic nomogram to guide the decision for post-surgical adjuvant transarterial chemoembolization (PA-TACE) in patients with hepatitis B virus-related (HBV) hepatocellular carcinoma (HCC). RESULTS: The 1, 3, 5-year overall survival rates were, respectively, 87.7%, 52.1% and 28.3% in the patients from the derivation set and 91.7%, 57.1% and 34.1% in those from the validation set. Five risk factors (HBV-DNA level, platelet count, vascular invasion, change of Child-Pugh score, and tumor diameter) in the multivariate analysis were significantly associated with prognosis. The statistical nomogram incorporated these five factors achieved good calibration and discriminatory abilities with c-index of 0.75 (95% CI 0.67 to 0.83). The findings were supported by the independent external validation set (c-index, 0.69; 95% CI 0.56 to 0.83). Patients who had a nomogram score of less than 180 was considered to have higher survival benefit from PA-TACE. METHODS: The nomogram was established based on data obtained from a retrospective study on 235 consecutive patients with HBV HCC who received PA-TACE as an initial therapy from 2006 to 2010 in our center. 84 patients who were collected at another institution between 01/2008 and 12/2010 served as an external validation set. The prognostic nomogram was developed based on the data obtained before the PA-TACE procedure. Predictive accuracy and discriminative ability of the nomogram were assessed by concordance index (C-index), calibration curves, and validation set. CONCLUSIONS: The novel nomogram may achieve an optimal prognostic prediction for PA-TACE in HBV-related HCC.
