Objective: To investigate the clinical value of the bipolar tweezers-clamp for the hepatic parenchymal transection in the resection of hepatocellular carcinoma. Methods: From January 2020 to January 2021,63 patients with the hepatocellular carcinoma for hepatectomy at Department of Hepatopancreatobiliary Surgery,Yuebei People's Hospital Affiliated to Shantou University Medical College were analyzed retrospectively.According to the different instruments used in the hepatic parenchymal transection,the patients were divided into bipolar tweezers-clamp group and ultrasonic scalpel group.There were 32 patients in bipolar tweezers-clamp group,with age of (55.5±10.5)years(range:37 to 78 years),including 22 males and 10 females,tumor size was (6.0±3.4)cm(range:2.4 to 13.4 cm). There were 6 patients with portal vein tumor thrombus and 5 patients with portal hypertension. There were 31 patients in ultrasonic scalpel group,with aged(57.8±10.1)years(range:37 to 79 years),including 27males and 4 females,tumor size was(7.9±5.1)cm(range: 2.4 to 21.3 cm),3 patients with portal vein tumor thrombus and 2 patients with portal hypertension. The preoperative baseline data,operation time,blood loss,postoperative liver function and the complications were compared between two groups using t test,χ² test and Fisher exact probabilityrespectively. Results: The operation was successfully completed in both groups.Compared with the ultrasonic scalpel group,the operation time was significantly shorter((219.3±76.4)minutes vs.(294.0±100.8)minutes,t=-3.322,P=0.002),the blood loss was less((250(475)ml vs. 500(1 050)ml,t=-2.307,P=0.026),the concentrate red blood cells transfusion volume was less(0.92(0.88)U vs. 2.32(4.00)U,Z=-1.987,P=0.047) in the bipolar tweezers-clamp group.The postoperative serum ALB level was higher in the bipolar tweezers-clamp group than that in the ultrasonic scalpel group((33.5±6.1)g/L vs. (29.5±4.2)g/L,t=3.226,P=0.020) on postoperative day 1;((35.7±4.5)g/L vs.(30.1±3.2)g/L,t=5.575,P<0.01) on postoperative day 3;((33.2±3.7)g/L vs. (31.0±4.4)g/L,t=3.020,P=0.004) on postoperative day 7. There was no significant difference in serum ALT,TBIL and PT level between the two groups(all P>0.05).No postoperative bile leakage occurred in both groups.The postoperative complications occurred in 8 cases(25.0%)in the bipolar tweezers-clamp group,including liver failure in one,and in 11 cases(35.5%)in the ultrasonic scalpel group,including liver failure in two(P>0.05). Conclusion: The bipolar tweezers-clamp is a safe and reliable method for the hepatic parenchymal transaction,which is quick and less bleeding during the hepatic resection.

OBJECTIVE: To explore the diagnostic value of the serum metabolites identified by high-performance liquid chromatography-mass spectrometry (HPLC/MS) for hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC). METHODS: A total of 126 patients admitted to Tianjin Third Central Hospital were enrolled, including 27 patients with HBV-related hepatitis with negative viral DNA (DNA-N), 24 with HBV-related hepatitis with positive viral DNA, 24 with HBV-related liver cirrhosis, 27 with HBV-related HCC undergoing surgeries or radiofrequency ablation, and 24 with HBV-related HCC receiving interventional therapy, with 25 healthy volunteers as the normal control group. Serum samples were collected from all the subjects for HPLC/MS analysis, and the data were pretreated to establish an orthogonal partial least- squares discriminant analysis (OPLS-DA) model. The differential serum metabolites were preliminarily screened by comparisons between the HBV groups and the control group, and the characteristic metabolites were identified according to the results of non-parametric test. The potential clinical values of these characteristic metabolites were evaluated using receiver operator characteristic curve (ROC) analysis. RESULTS: A total of 25 characteristic metabolites were identified in the HBV- infected patients, including 9 lysophosphatidylcholines, 2 fatty acids, 17α-estradiol, sphinganine, 5-methylcytidine, vitamin K2, lysophosphatidic acid, glycocholic acid and 8 metabolites with few reports. The patients with HBV- related HCC showed 22 differential serum metabolites compared with the control group, 4 differential metabolites compared with patients with HBV-related liver cirrhosis; 10 differential metabolites were identified in patients with HBV-related HCC receiving interventional therapy compared with those receiving surgical resection or radiofrequency ablation. From the normal control group to HBV-related HCC treated by interventional therapy, many metabolites underwent variations following a similar pattern. CONCLUSIONS We identified 25 characteristic metabolites in patients with HBV-related HCC, and these metabolites may have potential clinical values in the diagnosis of HBV-related HCC. The continuous change of some of these metabolites may indicate the possibility of tumorigenesis, and some may also have indications for the choice of surgical approach.

PURPOSE: Hepatocellular carcinoma (HCC) is an aggressive disease with high recurrence rate. However, current staging systems were lack of predictive capacity for HCC recurrence. We aimed to develop prognostic nomograms based on inflammation-related markers for HCC patients underwent hepatectomy. MATERIALS AND METHODS: We recruited 889 surgically treated patients from two medical centers. Independent prognostic factors were identified by cox regression analyses. Nomograms for recurrence-free survival (RFS) and overall survival (OS) were established, and validated internally and externally. The performance, discrimination, and calibration of nomograms were assessed, and compared with existed staging systems. RESULTS: Neutrophil to lymphocyte ratio (NLR) and gamma-glutamyl transpeptidase to platelet ratio (GPR) were the two inflammation-related factor that independently correlated with survival. NLR, GPR, international normalized ratio (INR), microvascular invasion, satellite lesions, tumour number, tumour diameter, and macrovascular invasion were used to construct nomogram for RFS while GPR, total bilirubin, INR, α-fetoprotein, microvascular invasion, satellite lesions, tumour diameter, and macrovascular invasion were for OS. In the training cohort, the C-index of nomogram was 0.701 (95% confidence interval [CI], 0.669 to 0.732) for RFS and 0.761 (95% CI, 0.728 to 0.795) for OS. These results received both internal and external validation with C-index of 0.701 (95% CI, 0.647 to 0.755) and 0.707 (95% CI, 0.657 to 0.756) for RFS, and 0.706 (95% CI, 0.640 to 0.772) and 0.708 (95% CI, 0.646 to 0.771) for OS, respectively. The nomograms showed superior accuracy to conventional staging systems (p<0.001). CONCLUSION: The nomograms based on inflammation-related markers are of high efficacy in predicting survival of HCC patients after hepatectomy, which will be valuable in guiding postoperative interventions and follow-ups.

Biomarkers for hepatocellular carcinoma (HCC) following curative resection are not currently sufficient for prognostic indication of overall survival (OS) and disease-free survival (DFS). The aim of this study was to investigate the prognostic performance of osteopontin (OPN), matrix metalloproteinase 7 (MMP7), and pregnancy specific glycoprotein 9 (PSG9) in patients with HCC. A total of 179 prospective patients with HCC provided plasma before hepatectomy. Plasma OPN, MMP7, and PSG9 levels were determined by enzyme-linked immunosorbent assay. Correlations between plasma levels, clinical parameters, and outcomes (OS and DFS) were overall analyzed. High OPN ( ⩾ 149.97 ng/mL), MMP7 ( ⩾ 2.28 ng/mL), and PSG9 ( ⩾ 45.59 ng/mL) were prognostic indicators of reduced OS (P < 0.001, P < 0.001, and P = 0.007, respectively). Plasma PSG9 protein level was an independent factor in predicting OS (P = 0.008) and DFS (P = 0.038). Plasma OPN + MMP7 + PSG9 elevation in combination was a prognostic factor for OS (P < 0.001). OPN was demonstrated to be a risk factorassociated OS in stage I patients with HCC and patients with low α-fetoprotein levels ( < 20 ng/mL). These findings suggested that OPN, MMP7, PSG9 and their combined panels may be useful for aiding in tumor recurrence and mortality risk prediction of patients with HCC, particularly in the early stage of HCC carcinogenesis.

BACKGROUND: Performing transarterial chemoembolization (TACE) is difficult with the occurrence of thrombocytopenia in cirrhotic patients with hepatocellular carcinoma (HCC). We aimed to evaluate the long-term efficacy and safety of partial splenic embolization (PSE) combined with TACE in patients with HCC with severe thrombocytopenia related to splenomegaly. METHODS: We conducted a case–control study consisting of 18 HCC patients with severe thrombocytopenia (< 50 × 109/L) who underwent PSE concurrently with TACE (PSE group) and 72 controls who underwent TACE alone (non-PSE group). RESULTS: Mean platelet counts at 1 month and 1, 3, and 5 years after concurrent PSE and TACE significantly increased compared with baseline (all P < 0.05), whereas the platelet count did not significantly increase after TACE alone. In addition, the platelet count at several time points after treatment in the PSE group was significantly higher than that in the non-PSE group, although the baseline platelet count in the PSE group was significantly lower than that in the non-PSE group. The platelet increase after PSE significantly reduced the need for platelet transfusions (P = 0.040) and enabled the subsequent TACE procedures in time (P = 0.046). The leukocyte counts and hemoglobin concentrations after concurrent PSE and TACE were also significantly increased, without deterioration of Child-Turcotte-Pugh score and unexpected side effects. CONCLUSION: PSE combined with TACE is effective in inducing and maintaining long-term thrombocytopenia improvement which reduces the need for the platelet transfusion and helps to perform initial and serial TACE, and is well-tolerated in patients with HCC and thrombocytopenia. PSE may be a promising treatment option for HCC patients with severe thrombocytopenia associated with splenomegaly who will undergo TACE.

The coagulation profile of patients with end-stage liver disease (ESLD) is different from that of healthy individuals. Because hemostasis is rebalanced in chronic liver disease, prophylactic transfusion of blood products may be not necessary for these patients even if they show severe coagulation dysfunction in conventional coagulation results. A 44-year-old man with hepatocellular carcinoma, cholangiocarcinoma and liver cirrhosis was scheduled for extra-hepatic mass excision under general anesthesia. His preoperative tests showed severe thrombocytopenia 19 × 10⁹/L. The patient underwent extrahepatic mass excision surgery under general anesthesia without transfusion of blood products. The post-operative course was uneventful without requiring any further hemostatic therapy. In this case report, we focus on the concept of rebalanced hemostasis in ESLD, and coagulation management based on rotational thromboelastometry.

Clinical outcomes of living donor liver transplantation (LDLT) for hepatocellular carcinoma (HCC) in patients with multiple myeloma (MM) have not been established in terms of HCC recurrence and MM deterioration after LDLT. A 51-year-old man with chronic hepatitis B was diagnosed with HCC and MM. Since the patient also had decompensated liver cirrhosis (LC), he underwent LDLT prior to autologous peripheral blood stem cell transplantation (PBSCT) to prevent fulminant hepatitis due to HBV reactivation. The patient received Epstein-Barr virus prophylaxis and a triple immunosuppressive regimen of tacrolimus, everolimus, and steroid after LDLT. Autologous PBSCT was performed 7 months after LDLT. He showed a complete response to treatment of MM without post-LT complications or HCC recurrence. In conclusion, LDLT could be adapted for treatment of MM patients with combined HCC and decompensated LC because it is an effective strategy of preventing HBV reactivation and HCC recurrence after induction therapy of MM.

Angiomyolipoma (AML) is a rare benign mesenchymal tumor in the liver, which is composed of blood vessels, smooth muscle, and adipose cells. The proportion of each component varies, making a diagnosis difficult. This paper reports a case of AML in the liver without adipose tissue, mimicking a hepatocellular carcinoma (HCC), which was diagnosed by a surgical tissue biopsy. A 65-year-old woman was admitted for an evaluation of a hepatic mass that had been detected by ultrasonography. The serologic markers of viral hepatitis B and C were negative. The liver function tests and alpha fetoprotein level were within the normal limits. Magnetic resonance imaging revealed a 1.9 cm sized mass in segment 6 of the liver with early arterial enhancement and washout on the delayed phase accompanied by a rim-like enhancement, which is similar to the imaging findings of HCC. A frozen section examination during surgery indicated a hepatocellular neoplasm and suggested the possibility of HCC. On the other hand, the final pathologic diagnosis was epithelioid myoid type of AML with no adipose tissue component. The tumor cells were positive for human melanocyte B-45 and negative for cytokeratin and hepatocyte paraffin 1. This paper reports a very rare case of AML without adipose tissue in the liver mimicking HCC that was diagnosed by a surgical tissue biopsy.

BACKGROUND/AIMS: The treatments and outcomes of hepatocellular carcinoma (HCC) with bile duct invasion are not well known. We aimed to confirm the safety of transarterial chemolipiodolization (TACL) and identify prognostic factors for patients with bile duct invasion treated with TACL. METHODS: Fifty patients with central bile duct invasion treated with TACL between 2005 and 2017 were enrolled. Patients were divided into three groups: hyperbilirubinemia (total bilirubin ≥2.5 mg/dL) with pre-TACL biliary drainage, hyperbilirubinemia without biliary drainage, and without hyperbilirubinemia. Tumor response to TACL, survival outcomes, length of hospitalization, adverse events using Common Terminology Criteria for Adverse Events (CTCAE), and factors affecting overall survival were compared. RESULTS: TACL-induced changes of mean CTCAE grades for albumin, alanine aminotransferase, creatinine, prothrombin time, and platelet were not significantly different among patients with or without initial hyperbilirubinemia. Serum bilirubin level was not significantly changed after TACL in all the three groups. Overall survival was not significantly different among the three groups (P=0.097). On multivariate analysis, alpha-fetoprotein < 400 ng/dL (hazard ratio [HR]=0.477, P=0.048) and highest total bilirubin level of < 2.5 mg/dL within one month after TACL (HR=0.335, P=0.004) were significantly associated with longer survival. CONCLUSIONS: TACL was a safe treatment for HCC patients with central bile duct invasion, irrespective of the presence of initial hyperbilirubinemia.

Radiofrequency ablation (RFA) is a minimally invasive procedure that has been considered as a relatively safe treatment for patients with small hepatocellular carcinoma (HCC). However, RFA has been shown to be associated with complications including mechanical and thermal damage. A 74-year-old man with hepatitis C virus-associated HCC was admitted to our hospital. Abdominal computed tomography revealed two lobulated-HCC in segments 4 and 5. He had no medical history of hypertension and cardiac disease. During RFA, blood pressure was elevated to 200/140 mmHg. There was no evidence of pulmonary embolism, aortic dissection, or ischemic heart disease. Laboratory findings for catecholamine surge were all within normal limits. After continuous intravenous nitroglycerin and oral beta-blocker treatment, patient's blood pressure gradually decreased and back within the normal range. Hypertensive crisis after RFA treatment for HCC is rare. Most reported cases of hypertensive crisis during RFA were related to adrenal gland injury with a release of catecholamine. In our case, the site of HCC was not close to the adrenal gland, and there was no evidence of catecholamine surge. Herein, we report a very rare case of hypertensive crisis without a surge in adrenal hormones after RFA treatment for HCC.
