Objective To compare anatomic resection (AR) and non-anatomic resection (NAR)for hepatocellular carcinoma (HCC) as a factor in preventing intra-hepatic recurrence and local recurrence after the initial surgical procedure.Methods A systematic review and Meta-analysis of nonrandomized trials comparing anatomic resection with non-anatomic resection for HCC published from 1990to 2010 in PubMed and Medline,Coehrane Library,Embase,and Science Citation Index were searched.Intra-hepatic recurrence,including early and late recurrence,and local recurrence were primary outcomes.5-year survival and 5-year disease-free survival were secondary outcomes.Pooled effect was calculated by utilizing either fixed effects model or random effects model.Result Eleven nonrandomized studies including 1576 patients were identified and analyzed.810 patients were in the AR group and 766 were in the NAR group.Patients in the AR group were characterized by lower prevalence of cirrhosis,more favorable hepatic function,and larger tumor size and higher prevalence of macrovascular invasion compared with patients in the NAR group.Anatomic resection significantly reduced the risks of local recurrence (OR,0.27; 95% CI,-0.17~0.43; P<0.001) and achieved a better 5-year disease-free survival (OR,2.10; 95% CI,-1.41 ~3.12; P=0.001) in HCC patients.Also,anatomic resection was marginally effective in decreasing early intra-hepatic recurrence.However,anatomic resection was not advantageous in preventing late intra-hepatic recurrence.No significant differences were found between the AR and NAR groups with respect to postoperative morbidity,mortality,and length of hospitalization.Conclusion Anatomic resection was recommended to be superior to non-anatomic resection in reducing the risks of local recurrence,early intra-hepatic recurrence and achieving a better 5-year disease-free survival in HCC patients.

Objective To evaluate the impact of different treatment strategies on patients with hepatocellular carcinoma (HCC) of less than 10 cm but with portal vein tumor thrombus (PVTT),and to investigate the prognostic factors.Methods Between 2003 and 2008,338 HCC patients with PVTT from the Affiliated Tumor Hospital,Guangxi Medical University,were retrospectively studied.These patients were divided into four groups:the conservative treatment group (n =75),the transarterial chemoembolization (TACE) group (n=86),the surgical resection group (n =90) and the surgical resection with postoperative TACE group (n=87).Survival rates were analyzed by the Kaplan-Meier method and differences among groups were compared using the log-rank analysis.The Cox' s proportional hazards model was performed to explore the risk factors of survival.Results The mean survival periods of patients in the four groups were 3.8,7,8.2,15.1 months respectively.There were significant differences in survival rate among the 4 groups.The survival rates at 1-,2-,and 3-year in the surgical resection with postoperative TACE group were 49%,37% and 19%,which were significantly higher than the other 3 groups (P<0.05).The 1-,2-,and 3-year survival rates in the surgical resection group were 28%,20% and 15% compared with 17.5%,0% and 0% in the TACE group.The survival rates were significantly higher after surgical resection than TACE (P<0.05).The 1-,2-,and 3-year survival rates in the conservative treatment group were 0%.These were the lowest among the four groups (P<0.05).Univariate analysis indicated that portal vein occlusion by tumor thrombus was a significant predictor of poor prognosis.Multivariate analysis revealed that the strategy of treatment (TACE) and the number of TACE cycles were independent survival predictors for HCC patients with PVTT.Conclusions Surgical resection is the most effective therapeutic strategy for HCC patients with PVTT and with good liver functional reserve.Postoperative TACE is necessary in preventing recurrence and prolonging survival in patients who could tolerate chemoembolization.TACE should be recommended as an effective and safe treatment for unresectable HCC patients with PVTT.The treatment provided a significantly better survival than conservative treatment.

OBJECTIVETo evaluate the effect of additives on absorption of Coptis chinensis total alkaloid and their pharmacokinetics in mice.
METHODThe mice were fed with the mixture of C. chinensis total alkaloids and additives (1:1). And then the feces and orbital blood were taken to detect the content of total alkaloids by HPLC and their pharmacokinetics.
RESULTGlutin could make the absorption of jatrorrhizine, coptisine, berberine and total alkaloids increased by 30%. Tween 80 and arabic gum did not affect the absorption of berberine, but inhibit that of other alkaloids. There had no influence of lecithin on the absorption of alkaloids. The peak time of total alkaloids in blood were 2 h (Cmax 1=5.9 mg x L(-1)) and 5.0 h (Cmax 2=3.4 mg x L(-1)), respectively, AUC was 17.6 mg x h x L(-1), the elimination of Half-life t1/2 was 5.2 h. After addition of glutin, the peak time of total alkaloids in blood were 1.5 h (Cmax 1=7.6 mg x L(-1)) and 4.8 h (Cmax 2=8.5 mg x L(-1)), AUC was up to 31.1 mg x h(-1) x L(-1), the elimination of Half-life t1/2 was 6.2 h.
CONCLUSIONGlutin could accelerate the mice on the absorption of C. chinensis total alkaloids, to extend the elimination half-life, increase the blood concentration and bioavailability.

Objective:
To study the clinical application of three-dimensional (3D) visualization technology in liver resection of complicated liver cancer.
Methods:
A retrospective analysis of 28 patients with complicated liver cancer treated from June 2017 to June 2018 in the Department of Hepatobiliary Surgery, the Affiliated Tumor Hospital of Guangxi Medical University. There were 26 males and 2 females, aged (46±10) years old. A treatment plan on how to perform liver resection for these patients was developed under the guidance of 3D visualization technology. The actual surgical procedures, operation time, intraoperative blood loss, and postoperative complications were documented. The virtual resected liver volume was compared with the actual resected liver volume. The virtual surgical resection margin was also compared with the actual surgical resection margin.
Results:
All the 28 patients with complicated liver cancer completed the 3D visualization analysis with the location, shape and quantity of tumor being clearly shown. Of the 27 patients who underwent liver resection, 13 underwent anatomical hepatectomy, and 14 underwent non-anatomical hepatectomy. The operation time ranged from 145 to 350 min (median 240 min). The intraoperative blood loss ranged from 100 to 1 500 ml (median 300 ml). The incisional wound healed slowly in 4 patients, pleural effusion developed in 8 patients, and ascites in 2 patients. There were no significant differences in the virtual resected liver volume compared with the actual resected liver volume (

Objective To study the value of serum prealbumin-bilirubin score (PALBI) in predicting posthepatectomy liver failure (PHLF) for patients with HBV related hepatocellular carcinoma (HCC).Methods A retrospective study was conducted on 919 HBV-related HCC patients who underwent hepatectomy from September 2013 to December 2016 at the Affiliated Tumor Hospital of Guangxi Medical University.These patients were divided into a training cohort (n =689) and a validation cohort (n =230) using the 3 ∶ 1 matching principle.The training cohort was divided into the control group (n=546) and the PHLF group (n=143) according to whether PHLF occurred.The multivariate logistic regression model was used to analyze the factors related to PHLF in the training cohort,and then the PALBI score was established.The ability of the PALBI score to predict PHLF was evaluated by the area under the receiver operating characteristic curve (AUC) and compared with the Child-Pugh,model for end-stage liver disease (MELD),and albumin-bilirubin (ALBI) scores.Results Univariate and multivariate logistic regression analyses showed the factors including HBV-DNA≥ 103 IU/ml,total bilirubin,prealbumin,platelet count,AST,prothrombin time,intraoperative blood loss ≥400 ml and major liver resection were closely related to PHLF.The ability of the PALBI score (AUC =0.733) to predict PHLF preoperatively was superior to the ChildPugh score (AUC =0.562),the MELD score (AUC =0.652) and the ALBI score (AUC =0.683) in the entire training cohort.Similar results were obtained in the entire validation cohort (AUC:0.752 vs.0.599 vs.0.641 vs.0.678).To eliminate the effect of a small residual liver volume on PHLF,the ability of each of these scores in the training and validation cohorts to predict PHLF was calculated respectively in these 2 cohorts of patients who underwent only minor liver resection,and similar results were obtained.Conclusion The PALBI score was significantly superior to the Child-Pugh,MELD and ALBI scores in predicting PHLF in patients with HBV-related HCC who underwent liver resection.The PALBI score is a simple,non-invasive and reliable novel model in predicting PHLF.

PVTT,and median survival time,1-,3-and 5-year survival rates were respectively 13 months,51.4%,26.0% and 17.3%;21 were in type Ⅲ PVTT,and median survival time,1-,3-and 5-year survival rates were respectively 7 months,9.5%,4.8% and 0,showing a statistically significant difference in survival (x2=18.102,P<0.05).The median survival time,1-,3-and 5-year survival rates were respectively 21 months,72.5%,42.5%,26.2% in 51 patients undergoing tumor and TT resection and 9 months,40%,14.4%,0 in 89 patients undergoing tumor resection + PVTT removal through incising portal vein,showing a statistically significant difference in survival (x2=24.098,P<0.05).③ Of 36 HCC patients with HVTT,17 were detected in right HVTT,and median survival time,1-,3-and 5-year survival rates were respectively 14 months,64.7%,20.2% and 0;10 were detected in left HVTT,and median survival time,1-,3-and 5-year survival rates were respectively 53 months,80.0%,70.0% and 38.9%;9 were detected in middle HVTT,and median survival time,1-,3-and 5-year survival rates were respectively 40 months,88.9%,61.0% and 30.5%;showing no statistically significant difference in survival (x2 =5.951,P>0.05).④ Of 44 HCC patients with BDTT,24,6 and 14 were respectively detected in type Ⅰ,Ⅱ and Ⅲ BDTTs,and median survival time,1-,3-and 5-year survival rates were respectively 38 months,87.5%,60.4%,34.9% in type Ⅰ BDTT patients and 26 months,83.3%,16.7%,0 in type Ⅱ BDTT patients and 35 months,78.6%,50.0%,21.4% in type Ⅲ BDTT patients,showing no statistically significant difference in survival (x2 =5.312,P>0.05).Of 44 patients,median survival time,1-,3-and 5-year survival rates were respectively 38 months,91.3%,59.5%,34.3% in 23 patients undergoing tumor and TT resection and 26 months,85.7%,35.7%,15.3% in 21 patients undergoing tumor resection + TT removal through incising common bile duct,showing no statistically significant difference in survival (x2 =2.071,P>0.05).Conclusions HCC patients with PVTT have larger tumor diameter and worse liver dysfunction,and are prone to peritoneal effusion.HCC patients with different LVI undergo surgery.There is better prognosis in HCC patients with BDTT,and good prognosis in patients with HVTT,while poorer prognosis in patients with PVTT.The postoperative survival of HCC patients with PVTT is associated with TT type,and patients will have better prognosis after tumor resection + TT removal if TT type is confirmed earlier.The postoperative survival of HCC patients with BDTT is not associated with TT type,tumor resection + TT removal maybe prolong postoperative survival time.

Hepatocellular carcinoma (HCC) is one of the most common malignancies and a leading cause of cancer-related death worldwide. Surgery remains the primary and most successful therapy option for the treatment of early- and mid-stage HCCs, but the high heterogeneity of HCC renders prognostic prediction challenging. The construction of relevant prognostic models helps to stratify the prognosis of surgically treated patients and guide personalized clinical decision-making, thereby improving patient survival rates. Currently, the prognostic assessment of HCC is based on several commonly used staging systems, such as Tumor-Node-Metastasis (TNM), Cancer of the Liver Italian Program (CLIP), and Barcelona Clinic Liver Cancer (BCLC). Given the insufficiency of these staging systems and the aim to improve the accuracy of prognostic prediction, researchers have incorporated further prognostic factors, such as microvascular infiltration, and proposed some new prognostic models for HCC. To provide insights into the prospects of clinical oncology research, this review describes the commonly used HCC staging systems and new models proposed in recent years.
