Background and Aim: The evidences for use of postoperative antibiotics (POA) in hepatocellular carcinoma (HCC) patients who underwent hepatectomy are controversial. We aimed to explore the relationship between POA and hepatectomy-related infection in a hepatitis B virus (HBV)-related HCC population., Methods: We retrospectively collected 934 HCC patients who underwent hepatectomy for curative intent from three tertiary hospitals in China. The incidences of postoperative infection including surgical site infection and remote site infection were recorded and calculated. Univariable and multivariable logistic regression analyses were performed to explore related factors of postoperative infection and POA. And the relationship between infection rates with different durations of POA was investigated., Results: The overall infection rate was 8.2% (77/934), including 6.5% (61/934) of surgical site infection and 2.0% (19/934) of remote site infection. Multivariable analysis revealed that the administration of POA was negatively related with the incidence of postoperative infection significantly (odds ratio = 0.50, 95% confidence interval = 0.30 to 0.83; P = 0.008). Albumin-bilirubin score, Barcelona Clinic Liver Cancer (BCLC) stage and extent of hepatectomy were independently related to the POA. And 3-day regimen seemed to be the shortest duration of POA to gain the lowest incidence of postoperative infection., Conclusions: Postoperative antibiotic is necessary for HBV-related HCC patients to prevent postoperative infection, especially for those with higher albumin-bilirubin score, at BCLC stage B-C, or who underwent major hepatectomy. For HBV-related HCC patients, postoperative second-generation cephalosporins, or ceftriaxone for 3 days after surgery might be proper., (© 2021 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.)

Background and Aim: Prognosis of infiltrative hepatocellular carcinoma (iHCC) is poor, and the treatments selection based on efficacy is unclear. We performed this multicenter study to compare the efficacy of hepatic resection and transarterial chemoembolization (TACE) in treating patients with iHCC., Methods: We retrospectively analyzed the overall survivals (OS) in 319 patients with iHCC who were initially treated by hepatic resection (n = 133) or TACE (n = 186) at four tertiary centers. Fifty-eight patients in the TACE group were assessed as resectable and compared with the hepatic resection group in subgroup analysis. A propensity score matched (PSM) analysis was performed to reduce selection bias. Cox regression was performed to identify significant factors associated with OS., Results: The median OS time was significantly longer in the hepatic resection group than that in the TACE group, before and after PSM (before PSM, 17.5 vs 7.3 months, P < 0.0001; after PSM, 14.0 vs 7.3 months, P < 0.0001). The multivariable analysis indicated TACE as a risk factor of OS (hazard ratio = 2.233, 95% confidence interval = 1.492 to 3.341, P < 0.0001), as well as portal venous tumor thrombosis grades 3-4 and alpha fetal protein (AFP) > 400 ng/mL. In the subgroup analysis, the better efficacy of hepatic resection over TACE persisted regardless of the grade of portal venous tumor thrombosis and the level of AFP. As for resectable patients, hepatic resection still showed significant survival benefit (before PSM, 17.5 vs 11.2 months, P = 0.0013; after PSM, 14.0 vs 10.9 months, P = 0.0304)., Conclusion: Hepatic resection might be the better choice for patients with iHCC due to its better survival benefit than TACE., (© 2020 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.)

Background: The role of transarterial chemoembolization (TACE) as the standard treatment for intermediate-stage hepatocellular carcinoma (HCC) is being challenged by increasing studies supporting liver resection (LR); but evidence of survival benefits of LR is lacking. We aimed to compare the overall survival (OS) of LR with that of TACE for the treatment of intermediate-stage HCC in cirrhotic patients., Methods: A Markov model, comparing LR with TACE over 15 years, was developed based on the data from 31 literatures. Additionally, external validation of the model was performed using a data set (n = 1735; LR: 701; TACE: 1034) from a tertiary center with propensity score matching method. We conducted one-way and two-way sensitivity analyses, in addition to a Monte Carlo analysis with 10 000 patients allocated into each arm., Results: The mean expected survival times and survival rates at 5 years were 77.8 months and 47.1% in LR group, and 48.6 months and 25.7% in TACE group, respectively. Sensitivity analyses found that initial LR was the most favorable treatment. The 95% CI for the difference in OS was 2.42-2.46 years between the two groups (P < 0.001). In the validation set, the 5-year survival rates after LR were significantly better than those after TACE before (40.2% vs. 25.9%, P < 0.001) and after matching (43.2% vs 30.9%, P < 0.001), which was comparable to the model results., Conclusions: For cirrhotic patients with resectable intermediate-stage HCC, LR may provide survival benefit over TACE, but large-scale studies are required to further stratify patients at this stage for different optimal treatments., (© 2019 The Authors.

Purpose: To retrospectively compare the efficacy and safety of combined radiofrequency ablation and percutaneous ethanol injection (RFA-PEI) with repeat hepatectomy for elderly patients with initial recurrent hepatocellular carcinoma (HCC) after hepatic surgery., Methods: From January 2009 to June 2015, 105 elderly patients (≥70 years) who underwent RFA-PEI (n = 57) or repeated hepatectomy (n = 48) for recurrent HCC ≤ 5.0 cm were included in the study. The overall survival (OS) and recurrence-free survival (RFS) were analysed with the Kaplan-Meier method and compared by the log-rank test. Non-tumour-related death, complications and hospital stays were assessed. Univariate and multivariate analyses were performed to identify the prognostic significance of the variables in predicting the OS and RFS., Results: OS rates were 78.2%, 40.8% and 36.7% at 1, 3 and 5 years after RFA-PEI and 76.3%, 52.5% and 42.6% after repeat hepatectomy, respectively (p = 0.413). Correspondingly, the 1-, 3- and 5-year RFS rates after RFA-PEI and repeat hepatectomy were 69.5%, 37.8%, 33.1% and 73.1%, 49.7%, 40.7%, respectively (p = 0.465). Non-tumour-related deaths in the RFA-PEI group (2/57) were significantly fewer than those in the repeat hepatectomy group (10/48) (p = 0.016). RFA-PEI was superior to repeat hepatectomy regarding the major complication rates and length of in-hospital stay (both p < 0.001). Multivariate analysis showed that the tumour number was the significant prognostic factor for the OS (hazard ratio (HR) = 1.961, 95% CI = 1.043-3.686, p = 0.037) and RFS (HR = 1.866, 95% CI = 1.064-3.274, p = 0.030)., Conclusion: RFA-PEI provides comparable OS and RFS to repeat hepatectomy for elderly patients with small recurrent HCC after hepatectomy but with fewer non-tumour-related deaths, major complications and shorter hospital stays.

Objectives: To compare combined percutaneous radiofrequency ablation and ethanol injection (RFA-PEI) with hepatic resection (HR) in the treatment of resectable solitary hepatocellular carcinoma (HCC) with 2.1-5.0 cm diameter., Methods: From June 2009 to December 2015, 271 patients whom underwent RFA-PEI (n = 141) or HR (n = 130) in three centres were enrolled. The overall survival (OS) and recurrence-free survival (RFS) between groups were compared with Kaplan-Meier method and log-rank tests. Complications, hospital stay and cost were assessed., Results: The OS rates at 1, 3 and 5 years were 93.5%, 72.7%, 58.6% in RFA-PEI group and 82.3%, 57.5%, 51.8% in HR group (p = 0.021). The corresponding 1-, 3- and 5-year RFS rates were 65.8%, 41.3%, 34.3% in RFA-PEI group and 50.5%, 33.8%, 28.4% in HR group (p = 0.038). For patients with 2.1-3.0 cm tumours, the 1-, 3- and 5-year OS after RFA-PEI and HR were 98.0%, 82.3%, 74.2% and 89.4%, 65.1%, 61.9%, respectively (p = 0.024). The corresponding RFS were 79.6%, 54.7%, 45.1% in RFA-PEI group, and 57.6%, 43.9%, 31.7% in HR group, respectively (p = 0.020). RFA-PEI was superior to HR in major complication rates, length of hospital stay and cost (all p < 0.001)., Conclusion: RFA-PEI had a survival benefit over HR in the treatment of solitary HCCs, especially for those with 2.1-3.0 cm in diameter., Key Points: • RFA-PEI provided superior survival to HR in solitary HCC with 2.1-5.0 cm in diameter. • RFA-PEI is superior to HR in complications, length of hospital stay and cost. • RFA-PEI might be an alternative treatment for solitary HCC within 5.0 cm in diameter.

Hepatectomy is currently routinely performed in most hospitals in China. China owns the largest population of liver diseases and the biggest number of liver resection cases. A nationwide multicenter retrospective investigation involving 112 hospitals was performed, and focused on liver resection for patients with hepatocellular carcinoma (HCC). 42,573 cases of hepatectomy were enrolled, and 18,275 valid cases of liver resection for HCC patients were selected for statistical analysis. The epidemiology of HCC, distribution of hepatectomy, postoperative complications and prognosis were finally analyzed. In the 18,275 HCC patients, 81% had hepatitis B virus infection and 10% had hepatitis C virus infection. 38% of the HCC patients had normal Alphafetoprotein (AFP) level, and other 35% had an AFP level lower than 400 ng mL -1 . In the study period, 97% of the hepatectomy for HCC were treated with open surgery, and 23.81% had vascular exclusion techniques. The operation time was (191.7±105.6) min, the blood loss was (546.0±562.8) mL, and blood transfusion was (543.0±1,035.2) mL. The median survival for HCC patients was 631 days, with 1-, 3-, and 5-year overall survival of 73.2%, 28.8% and 19.6%, respectively. Liver cirrhosis, multiple nodules, tumor thrombosis and high AFP level were risk factors that affect postoperative survival.

Purpose: Various inflammation-based prognostic biomarkers such as the platelet to lymphocyte ratio and neutrophil to lymphocyte ratio, are related to poor survival in patients with intrahepatic cholangiocarcinoma (ICC). This study aims to investigate the prognostic value of the aspartate aminotransferase to neutrophil ratio index (ANRI) in ICC after hepatic resection., Materials and Methods: Data of 184 patients with ICC after hepatectomy were retrospectively reviewed. The cut-off value of ANRIwas determined by a receiver operating characteristic curve. Preoperative ANRI and clinicopathological variables were analyzed. The predictive value of preoperative ANRI for prognosis of ICC was identified by univariate and multivariate analyses., Results: The optimal cut-off value of ANRI was 6.7. ANRI was associated with tumor size, tumor recurrence, white blood cell, neutrophil count, aspartate aminotransferase, and alanine transaminase. Univariate analysis showed that ANRI, sex, tumor number, tumor size, tumor differentiation, lymph node metastasis, resection margin, clinical TNM stage, neutrophil count, and carcinoembryonic antigen were markedly correlated with overall survival (OS) and disease-free survival (DFS) in patients with ICC. Multivariable analyses revealed that ANRI, a tumor size > 6 cm, poor tumor differentiation, and an R1 resection margin were independent prognostic factors for both OS and DFS. Additionally, preoperative ANRI also had a significant value to predict prognosis in various subgroups of ICC, including serum hepatitis B surface antigen‒negative and preoperative elevated carbohydrate antigen 19-9 patients., Conclusion: Preoperative declined ANRI is a noninvasive, simple, and effective predictor of poor prognosis in patients with ICC after hepatectomy.

Background: Malnutrition and immunological status are associated with survival in many cancers. Prognostic nutritional index (PNI) and body mass index (BMI) are recognized immune-nutritional indices and associated with postoperative outcome in hepatocellular carcinoma (HCC) patients. However, this association is still controversial. Our aim was to determine whether the combination of PNI and BMI is better than either alone in HCC patients' prognosis., Material and Methods: Preoperative PNI and BMI, patient demographics, clinical and pathological data from 322 HCC patients were collected and analyzed., Results: Low PNI was correlated with age, cirrhosis, total bilirubin (TBIL) ≥34.2 μmol/L, and recurrence. Likewise, low BMI was associated with TBIL ≥34.2 μmol/L, portal vein tumor thrombi (PVTT), tumor size, tumor differentiation, TNM stage, and recurrence. Multivariate analysis identified TNM stage, PVTT, tumor size, PNI, and BMI as independent predictors of outcome in HCC patients. Low PNI combined with BMI (PNI + BMI) accurately predicted poorer outcome, particularly in patients with TNM stage I HCC. The predictive range of PNI + BMI was more sensitive than that of either alone., Conclusions: preoperative PNI/BMI is an independent predictor of outcome for HCC patients, especially in patients with early stage HCC. Intriguingly, the PNI + BMI combination can enhance the accuracy of prognosis., (Copyright © 2017 International Hepato-Pancreato-Biliary Association Inc. Published by Elsevier Ltd.

Background: Recently, increasing studies have revealed the association of inflammatory parameters, such as preoperative platelet count, and the prognosis of hepatocellular carcinoma (HCC). However, the link between the platelet count and the prognosis of patients with HCC after hepatic resection is still controversial., Methods: We searched PubMed, Web of Science, EMBASE, and CBM for relevant trials and analyzed outcomes with random-effects model. The hazard ratio (HR) and its 95% confidence interval (CI) were calculated., Results: In total, 31 studies, including a total of 10,730 patients, met our criteria. The results showed that thrombocytopenia in HCC patients was associated with poor overall survival (HR = 1.47, 95% CI: 1.21-1.78), disease-free survival (HR = 1.36, 95% CI: 1.08-1.72), and a high risk of cancer recurrence (HR = 1.41, 95% CI: 1.22-1.62), but a low risk of extrahepatic metastasis (HR = 0.55, 95% CI: 0.47-0.63)., Conclusions: The meta-analysis revealed that preoperative platelet count could act as a significant biomarker in the prognosis of HCC, especially a platelet count of <100 × 10 3 /mm 3 . Additional high-quality trials are needed, considering the low-quality studies analyzed., (Copyright © 2016 Elsevier Inc. All rights reserved.)

Introduction: This study evaluated long-term outcomes of salvage surgery as additional therapy following downstaging of hepatocellular carcinoma (HCC) with transarterial chemoembolization (TACE) in patients with initially unresectable HCC., Methods: A retrospective analysis was performed of 831 consecutive patients with unresectable HCC who underwent TACE as initial treatment between June 2004 and December 2014. Of these, 82 patients with downstaged resectable HCC were enrolled in this study: 43 received salvage surgery (S group) and the remaining 39, who refused salvage resection, were the control group (T group). The primary endpoint was overall survival (OS)., Results: The median OS in the S and T groups was 49 and 31 months, respectively (p = .027). The 2-, 4-, and 5-year survival rates were 93%, 47%, and 26% in the S group and 74%, 18%, and 10% in the T group, respectively (p = .019). Treatment modality (hazard ratio [HR], 0.337; 95% confidential interval [CI], 0.184-0.616; p < .001) and response to TACE (complete vs. partial; HR, 3.154; 95% CI, 1.709-5.822; p < .001) were independent prognostic factors for survival. The median OS for patients in the complete response and partial response (PR) subgroups was 50 and 49 months, respectively, in the S group and 54 and 24 months, respectively, in the T group (p = .699 and p < .001, respectively). The median OS for HCC patients with macroscopic vascular invasion (MVI) was 58 and 30 months in the S and T groups, respectively (p = .024)., Conclusion: Salvage surgery after downstaging of unresectable HCC had a survival benefit only for patients with MVI or a PR to TACE., Implications for Practice: The results of this study suggest that salvage liver resection after downstaging of unresectable hepatocellular carcinoma in patients with a complete response to transarterial chemoembolization (TACE) has a comparable long-term outcome in this good-prognosis group. Salvage liver resection may provide a better long-term outcome compared with TACE alone, but only in patients with macroscopic vascular invasion or those with a partial response to TACE., Competing Interests: of potential conflicts of interest may be found at the end of this article., (©AlphaMed Press.)

Introduction: To retrospectively evaluate the efficacy and safety of salvage resection(SR) for recurrence or metastasis of hepatocellular carcinoma (HCC) after initial percutaneous ablation therapy (PAT)., Methods: From September 2006 to September 2013, 50 consecutive patients who received SR for recurrent or metastatic HCC undergone initial PAT were enrolled. Safety and efficacy of SR for these patients were analyzed., Results: No treatment-related death occurred. Curative outcome was achieved in all the patients. The median overall survival after SR was 40 months, and the 1-, 3-, 5-year overall survival rate after SR was 85.2%, 46.4% and 34.8%, respectively. The disease-free survival was 38.6% at 1 year and 12.1% at 3 years after SR., Conclusion: SR is an effective and safe method for patients with recurrent or metastatic HCC after initial PAT treatment., (Copyright © 2016 IJS Publishing Group Ltd.

Gamma-glutamyltranspeptidase (γ-GGT), an oxidative stress marker, is correlated with inflammation in the extracellular hepatic microenvironment. This study aimed to evaluate the prognostic value of serum γ-GGT levels in patients with hepatocellular carcinoma (HCC) after hepatectomy. Three hundred and eight patients who underwent hepatic resection for HCC were included in the study. Preoperative serum γ-GGT levels, as well as demographic, clinical, and pathologic data, were analyzed. The optimal cutoff value of γ-GGT was 88 U/L. All patients were divided into γ-GGT ≤ 88 U/L group (n = 146) and γ-GGT > 88 U/L group (n = 162). The disease-free survival (DFS) and overall survival (OS) rates of patients in the γ-GGT > 88 U/L group were poorer than those in γ-GGT ≤ 88 U/L group. Preoperative serum γ-GGT levels, associating with gender, HBsAg status, tumor size, capsulation, tumor number, and vascular invasion, was an independent prognostic predictor of disease-free survival [hazard ratio (HR) = 1.616; 95 % confidence interval (CI), 1.223-2.135; P = 0.001] and overall survival (HR = 2.043; 95 % CI, 1.509-2.766; P < 0.001). Furthermore, γ-GGT was also associated with DFS and OS in small HCC (tumor size ≤5 cm) and alpha-fetoprotein (AFP) ≤ 200 ng/mL subgroup. In conclusion, γ-GGT is a promising and reliable prognostic biomarker in HCC patients after hepatic resection, especially for patients with small HCC or AFP ≤ 200 ng/mL.

Background/aims: To study the value of surgical treatment for hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT)., Methodology: From January 1997 to December 2001, 63 cases of HCC with portal vein tumor thrombus underwent liver resection combined with PVTT removal (group 1). Between December 2001 and December 2003, 20 patients received adjuvant portal vein chemotherapy (PVC) after the surgical procedures mentioned above (group 2). Treatment outcome and the surgical features in these two groups were studied., Results: The median overall survival in group 2 was significantly longer than that in group 1 (10.9 months vs. 7.8 months, p < 0.05). There were significant differences between the survival of the two groups (log-rank, p < 0.05). In group 1 the 1-, 3-, and 5-year survival rates were 18.0%, 14.8% and 1.6%, respectively. In group 2 the 1-year survival rate was 30%., Conclusions: Liver resection combined with PVTT removal and the postoperative PVC is beneficial to the survival of HCC patients with PVTT. Postoperative PVC might enhance the effect of these surgical approaches.

This study aimed to evaluate the prognostic value of serum γ-GGT levels in patients with hepatocellular carcinoma (HCC) after hepatectomy. Three hundred and eight patients who underwent hepatic resection for HCC were included in the study. Preoperative serum γ-GGT levels, as well as demographic, clinical, and pathologic data, were analyzed. The optimal cutoff value of γ-GGT was 88 U/L. All patients were divided into γ-GGT ≤ 88 U/L group ( n = 146) and γ-GGT > 88 U/L group ( n = 162). The disease-free survival (DFS) and overall survival (OS) rates of patients in the γ-GGT > 88 U/L group were poorer than those in γ-GGT ≤ 88 U/L group. Preoperative serum γ-GGT levels, associating with gender, HBsAg status, tumor size, capsulation, tumor number, and vascular invasion, was an independent prognostic predictor of disease-free survival [hazard ratio (HR) = 1.616; 95 % confidence interval (CI), 1.223-2.135; P = 0.001] and overall survival (HR = 2.043; 95 % CI, 1.509-2.766; P < 0.001). Furthermore, γ-GGT was also associated with DFS and OS in small HCC (tumor size ≤5 cm) and alpha-fetoprotein (AFP) ≤ 200 ng/mL subgroup. In conclusion, γ-GGT is a promising and reliable prognostic biomarker in HCC patients after hepatic resection, especially for patients with small HCC or AFP ≤ 200 ng/mL. [ABSTRACT FROM AUTHOR]
