Influence of triglyceride/high-density lipoprotein cholesterol ratio on the onset of primary liver cancer / 临床肝胆病杂志

ObjectiveTo investigate the influence of triglyceride （TG）/high-density lipoprotein cholesterol （HDL-C） ratio on the onset of primary liver cancer. MethodsA prospective cohort study was conducted. Physical examination data were collected from 99 750 cases of on-the-job and retired employees of Kailuan Group who participated health examination from July 2006 to December 2007， and they were followed up till December 31， 2021 to observe the onset of primary liver cancer. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups， and the Kruskal-Wallis H test was used for comparison of continuous data with skewed distribution between multiple groups； the chi-square test was used for comparison of categorical data between groups. According to the tertiles of TG/HDL-C ratio， the subjects were divided into Q1， Q2， and Q3 groups， and the incidence density of primary liver cancer was calculated for each group. The Kaplan-Meier method was used to calculate the cumulative incidence rate of primary liver cancer in each group， and the log-rank test was used to compare the difference in cumulative incidence rate between groups. The Cox proportional hazards model was used to analyze the influence of TG/HDL-C ratio on the onset of primary liver cancer. ResultsThere were significant differences between the three groups in age， proportion of male subjects， waist circumference， body mass index， fasting blood glucose， systolic pressure， diastolic pressure， triglyceride， total cholesterol， HDL-C， low-density lipoprotein cholesterol， alanine aminotransferase， high-sensitivity C-reactive protein， chronic liver diseases， hypertension， diabetes， the family history of malignant tumor， drinking， smoking， physical exercise， and educational level （P<0.05）. During the mean follow-up time of 14.06±2.71 years， there were 484 cases of new-onset liver cancer， among whom there were 446 male subjects and 38 female subjects. The incidence density of primary liver cancer was 0.39/1 000 person-years in the Q1 group， 0.35/1 000 person-years in the Q2 group， and 0.30/1 000 person-years in the Q3 group， and the cumulative incidence rates of primary liver cancer in the three groups were 6.03‰， 5.28‰， and 4.49‰， respectively， with a significant difference between the three groups based on the long-rank test （χ2=6.06， P=0.048）. After adjustment for the confounding factors considered， the Cox proportional hazards model showed that compared with the Q3 group， the Q1 group had a hazard ratio of 2.04 （95% confidence interval ［CI］： 1.61‍ ‍—‍ ‍2.58， Pfor trend<0.05）， and the Q2 group had a hazard ratio of 1.53 （95%CI： 1.21‍ ‍—‍ ‍1.92， Pfor trend<0.05）. ConclusionThe reduction in TG/HDL-C ratio is associated with an increase in the rask of primary liver cancer， especially in people with chronic liver diseases.

Research advances in neutrophil extracellular traps and liver diseases / 临床肝胆病杂志

Neutrophils play an immune defense role by releasing the proteases such as neutrophil elastase and myeloperoxidase to form neutrophil extracellular trap （NET） and participate in the inflammatory response of various liver diseases， but the excessive release of NET may worsen liver tissue damage and has thus become one of the risk factors for liver diseases. In recent years， studies have shown that the excessive release of NET can promote the progression of liver diseases （such as viral hepatitis， nonalcoholic steatohepatitis， and hepatic ischemia-reperfusion injury） to liver cancer， and clarifying the mechanism of action of NET is of great importance for the diagnosis and progression of liver diseases. Therefore， this article elaborates on the latest research advances in NET in liver diseases， so as to provide new insights into the diagnosis and treatment of liver diseases and the prevention of liver cancer.

Economic burden of liver disease in Colombia

Introduction: Liver diseases have a significant impact on global morbidity and mortality rates, primarily attributed to cirrhosis and hepatocellular carcinoma. However, the true extent of their impact on patients, healthcare systems, and countries is often underestimated. Materials and methods: This descriptive, cross-sectional study aimed to determine the economic burden associated with premature deaths caused by cirrhosis and primary liver cancer. The economic assessment was conducted by analyzing potentially productive years of life lost (PPYLL) due to liver diseases in Colombia between 2009 and 2016. Results and conclusions: The total burden of liver disease accounted for 687,861 disability-adjusted life years (DALYs). Men experienced a higher number of years of life lost from mortality (YLL), while women had a greater number of years lived with a disability (YLD). The economic burden of deaths caused by cirrhosis and primary liver cancer exceeded USD 8.6 million, highlighting the urgency to enhance intervention strategies ranging from promotion and prevention to timely diagnosis and treatment.

Construction and validation of a prognostic nomogram model of programmed death receptor 1 inhibitors in treatment of hepatitis B-related hepatocellular carcinoma / 肿瘤研究与临床

Objective:To investigate the factors influencing the prognosis of hepatitis B-related hepatocellular carcinoma treated with programmed death receptor 1 (PD-1) inhibitors, and to construct a prognostic nomogram model for these patients and evaluate its clinical significances.Methods:The clinical data of 121 patients with hepatitis B-related hepatocellular carcinoma treated with PD-1 inhibitors at the First Affiliated Hospital of Xinxiang Medical College from July 2018 to July 2021 were retrospectively analyzed. Follow-up was performed from the beginning of PD-1 inhibitor use, and the Kaplan-Meier method was used to analyze the overall survival of patients. The variables screened by the univariate Cox proportional hazards model analysis and variables clinically believed to be related to the prognosis were included in the multivariate Cox proportional hazards model for overall survival, and the stepwise regression method was used to screen the independent factors influencing overall survival. Based on the independent influencing factors of overall survival, R 3.5.1 software was used to construct a prognostic nomogram model for overall survival of hepatitis B-related hepatocellular carcinoma treated with PD-1 inhibitors. Calibration curve was used to the consistency of model prediction and practice. The Harrell consistency index and receiver operating characteristic (ROC) curve (with imaging diagnosis as the gold standard) were used to analyze the efficacy of model in predicting the 1-year and 2-year overall survival rates.Results:The median follow-up time of 121 patients was 12.40 months, and the median overall survival time was 14.30 months, with overall survival rates of 82.60% and 62.30% at 6 and 12 months. Multivariate Cox regression analysis showed that albumin (ALB) ( HR = 0.946, 95% CI 0.901-0.992), international normalized ratio (INR) ( HR = 32.034, 95% CI 5.046-203.362), aspartate aminotransferase (AST) ( HR = 1.010, 95% CI 1.007-1.012) were independent influencing factors for overall survival of patients. According to the three factors, a prognostic nomogram model for hepatitis B-related hepatocellular carcinoma treated with PD-1 inhibitors was constructed. The slope of the calibration curve of the model predicting 1-year and 2-year overall survival rates was close to 1. The Harrell consistency index of the nomogram model was 0.809 (95% CI 0.760-0.858). ROC curve analysis showed that the area under the curve (AUC) of the nomogram model predicting 1-year and 2-year overall survival rates of patients was 0.794 (95% CI 0.744-0.887, P < 0.001) and 0.791 (95% CI 0.708-0.860, P = 0.002). Conclusions:ALB, INR and AST are the influencing factors of prognosis of hepatitis B-related hepatocellular carcinoma patients treated with PD-1 inhibitors, and the nomogram model constructed based on prognostic influencing factors has a good effect on predicting the 1-year and 2-year overall survival rates of patients, which can be used to screen the population suitable for immunotherapy and is conducive to the clinical formulation of individualized and precise treatment plans.

Prenatal diagnosis and intrauterine treatment of a giant fetal hepatic hemangioma:a case report / 中华围产医学杂志

This article reported a case of fetal giant hepatic hemangioma with cardiomegaly managed with intrauterine treatment. At 23 weeks of gestation, the patient was referred to Guangdong Women and Children Hospital due to abnormal abdominal echogenicity of the fetus, which was suspected to be a hepatic hemangioma or a hepatic arteriovenous fistula. The prenatal ultrasound at 26 weeks of gestation revealed an enlarged fetal hepatic hemangioma of 45 mm×35 mm×42 mm and an enlarged heart (cardiothoracic area ratio of 0.50). So, with the patient's informed consent, the fetus was treated with intrauterine administration of propranolol and dexamethasone and closely monitored by ultrasound. The volume of the lump still increased at the beginning of the medication, but started to shrink in the 7th week. Besides, the fetal cardiac load was reduced and the condition was controlled. The patient delivered at 37 weeks of gestation. The baby received a CT examination on the fourth day after birth which revealed an abdominal mass of 40 mm×30 mm×44 mm requiring no treatment, and no abnormalities were reported during a one-year follow-up.

Clinicopathological diagnosis and treatment of undifferentiated(embryonal) sarcoma of the liver / 中华普通外科杂志

Objective:To investigate the clinicopathological features, differential diagnosis, treatment and prognosis of undifferentiated embryonal sarcoma of the liver (UESL).Methods:Five UESL cases operated on at Hunan Provincial People's Hospital from 2014 to 2021 were retrospectively analyzed. H&E and immunohistochemical staining were done for pathological observation.Results:The 5 UESL patients(two boys,three girls) were 0.5 to 15 years old, all underwent radical surgical resection. In 3 cases tumors located in right liver, 1 in left liver, 1 in both lobes. Radiographically and visually, the tumor is a large cystic solid mass, microscopically composed of myxoid stroma and undifferentiated stromal cells, with pleomorphic tumor giant cells and characteristic eosinophilic bodies. All 5 patients are now alive after surgical resection: 1 patient achieved disease-free survival of more than 91 months after surgery alone. Two patients had recurrence after surgery and received surgical resection plus chemotherapy or chemotherapy alone. They achieved survival of more than 35 and 16 months, respectively. Two patients were treated with chemotherapy or chemotherapy plus radiotherapy after surgery and survived more than 49 and 31 months without recurrence, respectively.Conclusions:UESL is a rare and highly malignant mesenchymal tumor with characteristic pathologic morphology. Radical resection is the key to the treatment for UESL, and chemotherapy and radiotherapy should be carried out after surgery.

Effect of intraoperative cell salvage on the number and viability of cancer cells in salvaged autologous blood from patients undergoing liver cancer surgery / 中华麻醉学杂志

Objective:To evaluate the effect of intraoperative cell salvage (ICS) on the number and viability of cancer cells in salvaged autologous blood from the patients undergoing liver cancer surgery.Methods:Twenty patients undergoing open radical primary hepatocellular carcinoma were selected, and blood from the operative field was collected after exposing the liver and treated with ICS. Blood specimens 20 ml from the surgical field (S 1), blood specimens 20 ml before ICS treatment-leukocyte depletion filter (LDF) filtration (S 2) and blood specimens 20 ml after LDF filtration (S 3) were collected and enriched, of which the blood sample 10 ml was used for cancer cell identification and count by immunofluorescence staining, and the remaining blood sample 10 ml was continuously cultured for 3 weeks, and then cell viability was observed by immunofluorescence method. Results:Hepatocellular carcinoma(HCC) cells were identified in 19 S 1 specimens, 18 S 2 specimens, and 16 S 3 specimens, but there was no significant difference in the detection rate among the three specimens ( P>0.05). Compared with S 1 specimens, HCC cell count was significantly reduced in S 2 and S 3 specimens ( P<0.05). There was no significant difference in the HCC cell count between S 3 specimens and S 2 specimens ( P>0.05). After 3 weeks of culture, the results of light microscopy showed that: hepatocellular carcinoma cell clusters were found in S1 specimens, and no hepatocellular carcinoma cell cluster was found in S 2 and S 3 specimens; the results of fluorescence microscopy showed that: 400 and 14 mixed epithelial-mesenchymal HCC cells and 100 and 21 mesenchymal HCC cells were found in S 1 and S 2 specimens, respectively, while no HCC cells were identified in S 3 specimens, among which HCC cells mainly presented as clusters of hepatocellular carcinoma cells in S 1 specimen, while no clusters of hepatocellular carcinoma cells were found in S 2 and S 3 specimens. Conclusions:After treatment with ICS or ICS-LDF, the number and viability of hepatocellular carcinoma cells in salvaged autologous blood are significantly reduced, and hepatocellular carcinoma cells exist as single cells and fail to develop clusters of hepatocellular carcinoma cells; LDF can reduce the risk of hepatocellular carcinoma cell autotransfusion to a certain extent, although it can not effectively filter out hepatocellular carcinoma cells continuously.

Diagnostic and prognostic value of 68Ga-FAPI PET for malignant tumors of the liver and biliary tract / 中华核医学与分子影像杂志

Objective:To investigate the diagnostic and prognostic value of 68Ga-fibroblast activation protein inhibitor (FAPI) PET for hepatobiliary malignancies. Methods:From July 2020 to February 2023, 33 patients (23 males, 10 females; age (55.4±13.5) years) with suspected or confirmed liver or biliary tract malignancies who underwent 68Ga-FAPI PET in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology were retrospectively analyzed. PET images were evaluated by 3 experienced nuclear medicine physicians, and the results of biopsy or postoperative pathology, clinical and imaging follow-up were used as the gold standard. One-way analysis of variance and least significant difference t test were used to compare the differences among groups. Survival analysis was performed using Kaplan-Meier curves and the log-rank test. Results:Of 33 patients, 14 performed PET for initial diagnosis and staging, and 19 for restaging. There were 14 patients with hepatocellular carcinoma (HCC), 13 patients with cholangiocarcinoma (CCA), and 6 patients with gallbladder carcinoma (GBC). The primary tumor of HCC, CCA and GBC all showed significant 68Ga-FAPI uptake, with no statistically significant difference in SUV max among groups ( F=1.58, P=0.250). The sensitivities of 68Ga-FAPI PET for initial diagnosis and restaging of hepatobiliary malignancies were 14/14 and 15/15, respectively. Compared with conventional imaging, 68Ga-FAPI PET changed the diagnosis and staging in 29.2%(7/24) patients. The treatment strategy was changed in 30.3%(10/33) patients with malignant tumors due to 68Ga-FAPI PET findings. Follow-up showed 22 cases survived and 11 cases died, with the overall survival of 355.56(80.00, 516.97) d, and 1- and 2-year survival rates were 68.2% and 57.9%, respectively. Semi-quantitative 68Ga-FAPI PET parameters such as SUV max, target-liver ratio (TLR), and target-blood ratio (TBR) had no significant prognostic value, but the prognosis of the group without distant metastases diagnosed by 68Ga-FAPI PET was significantly better than that of the group with distant metastasis ( P=0.032). Conclusion:68Ga-FAPI PET has high sensitivity for the diagnosis of hepatobiliary malignancies, which can help guide treatment decisions and prognosis evaluation.

Thought and practice of long-term management for hepatobiliary and pancreatic malignant tumors / 中华肝胆外科杂志

Radical resection is the only measurement to cure patients of hepatobiliary and pancreatic tumors. The comprehensive application of endoscopy, interventional therapy, radiotherapy and systemic therapy can not only significantly improve the early diagnosis rate of the disease, and successfully transform some borderline resectable tumors into radical resectable states, but also reduce the recurrence rate of tumors after surgery, thus prolonging the survival time of patients. In recent years, the continuous emergence of new systemic therapeutic drugs has brought new opportunities for patients with hepatobiliary and pancreatic malignancies, but the number of doctors participating in diagnosis and treatment has also increased accordingly. Therefore, the contradiction between the division system based on treatment methods and the orderly and standardized treatment is becoming more and more prominent. According to the latest progress of hepatobiliary and pancreatic cancer research at home and abroad, and combined with our clinical experience, we proposed a long-term management concept based on hepatobiliary and pancreatic comprehensive multi-technical team. Based on this concept, we have carried out new thought and practice on the diagnosis and treatment of patients with hepatobiliary and pancreatic malignant tumors.

Prognostic factors of spontaneous rupture hemorrhage in primary liver cancer / 中华肝胆外科杂志

Objective:To explore the independent influencing factors of patients with spontaneous rupture hemorrhage of primary liver cancer (PLC).Methods:A retrospective cohort study was conducted. The clinical data of 128 patients with PLC spontaneous rupture hemorrhage in Ningxia Medical University General Hospital from January 2017 to March 2022 were analyzed, including 108 males and 20 females, aged (53.4±10.6) years. According to different treatment, 128 patients were divided into liver resection group (LR, n=28), interventional group [ n=39, transcatheter arterial chemoembolization (TACE) and transcatheter arterial embolization (TAE)], and conservative group ( n=61). Univariate and multivariate Cox regression was performed to analyze prognostic factors. The LR and TACE groups were subdivided into LR (aLR, n=15), TACE/TAE (aTACE, n=33) and LR+ TACE ( n=19) groups. Kaplan-Meier analysis was performed, and the survival rate was compared by log-rank test. Results:The median survival time of LR group and TACE group was 23 months and 21 months, respectively, with no statistical significance ( P>0.05). The median survival time (38 months) in LR+ TACE group was significantly longer than that in aLR group (10 months) and aTACE group (9 months), and the difference was statistically significant ( P<0.05). Univariate analysis showed that Barcelona Clinical Liver Cancer (BCLC)staging, tumor length ≥10.0 cm, vascular invasion, α-fetoprotein ≥400 μg/L, total bilirubin, prothrombin time and treatment affected overall survival of PLC spontaneous rupture hemorrhage patients (all P<0.05). Multivariate analysis showed that BCLC staging, tumor length ≥10.0 cm, Child-Pugh grade and treatment were independent influencing factors for overall survival of PLC spontaneous rupture hemorrhage patients (all P<0.05). Conclusion:BCLC stage, tumor length ≥10.0 cm, Child-Pugh grade and treatment method are independent predictors of overall survival in patients with spontaneous rupture of PLC. LR combined with TACE therapy can improve the survival and prognosis of patients with spontaneous rupture of primary liver cancer.

Integrative treatment for primary liver cancer with tumor thrombosis in hepatic vein or inferior vena cava: a review / 中华肝胆外科杂志

Primary liver cancer is a common malignant tumor. Early liver cancer is suitable for surgical resection, local ablation, liver transplantation and other radical treatment, and the prognosis is better. Patients with advanced liver cancer often have tumor thrombosis in hepatic vein and inferior vena cava. With high rates of recurrence and metastasis, the prognosis is poor. Chinese guidelines recommend multidisciplinary treatment to patients with hepatic vein thrombosis and inferior vena cava thrombosis including local treatment, systematic anti-tumor drug treatment, surgical resection and other treatment. This article reviewed the progress in diagnosis and treatment of primary liver cancer with tumor thrombosis in hepatic vein and inferior vena cava in the past decade.

Efficacy and safety of laparoscopic surgery in treatment of recurrent hepatocellular carcinoma / 中华肝胆外科杂志

Objective:To study the efficacy and safety of laparoscopic surgery in treatment of recurrent hepatocellular carcinoma.Methods:The clinical data of 58 patients with recurrent hepatocellular carcinoma who underwent surgical treatment from January 2010 to January 2018 at Hunan Provincial People’s Hospital were retrospectively analyzed. There were 50 males and 8 females, ranging in age from 28 to 78 (53.0±10.8) years old. Patients were divided into laparoscopic group ( n=27) and laparotomy group ( n=31) according to different surgical procedures. The differences in operative time, intraoperative blood loss, hospital stay, postoperative anal exhaustion time, postoperative complications and prognosis between the two groups were compared. Results:The intraoperative blood loss of laparoscopy group and laparotomy group were 100.0(50.0, 400.0) ml vs 300.0(100.0, 500.0) ml, the postoperative anal exhaustion time were (2.7±0.6) d vs (3.3±0.6) d, the hospital stay were (14.8±3.8) d vs (21.4±6.3) d, and these differences were statistically significant (all P<0.05). The operative time of the two groups were (243.4±27.2) min vs (217.5±34.7) min, with no statistical significance ( t=0.59, P=0.344). There were no significant differences between the two groups in postoperative complications (bile leakage, abdominal infection, hemorrhage, pleural effusion and hepatic encephalopathy) (all P>0.05); thetumor free survival, 1-year, and 3-year overall survival rates of the two groups were also not significantly different (both P>0.05). Conclusion:Laparoscopic surgery is safe and effective in the treatment of recurrent hepatocellular carcinoma, and its prognosis is similar to laparotomy, its complications are not significantly increased, which is worthy of promotion in clinic.

Mechanism of Bielong Ruangan decoction in treatment of liver cancer based on network pharmacology and molecular docking / 中国医师杂志

Objective:To explore the key targets and mechanism of Bielong Ruangan decoction in the treatment of liver cancer based on network pharmacology and molecular docking.Methods:Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) database, PubChem database and PharmMapper database were used to search and screen the chemical components and related targets of Bielong Ruangan decoction and the targets of liver cancer diseases. The network diagram of " Bielong Ruangan decoction-traditional Chinese medicine-active ingredient-predicted target-disease" was constructed; Protein-protein interaction (PPI) network were analyzed through String database; gene ontology (GO) enrichment analysis was performed through WebGestalt database; Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis was carried out through KEGG Orthology Based Annotation System (KOBAS) database; Molecular docking of the active components and core target proteins of Bielong Ruangan decoction was carried out by using PyMOL, Auto DockVina and other software.Results:Bielong Ruangan decoction had 67 active components, 154 liver cancer targets and 244 pathways. According to the analysis of network pharmacology, Bielong Ruangan decoction may play an anti-cancer role through key targets such as epidermal growth factor receptor (EGFR), mitogen activated protein kinase 1 (MAPK1), estrogen receptor 1 (ESR1), MAPK8, serine threonine protein kinase 1 (AKT1), MAPK14, cysteine protease 3 (CASP3), cyclin-dependent kinase 2 (CDK2), bone morphogenetic protein 2 (BMP2), aldose reductase (AKR1B1) and other key targets. KEGG enrichment analysis showed that the treatment of liver cancer by Bielong Ruangan decoction involved the regulation of vascular endothelial growth factor (VEGF) signaling pathway, tumor necrosis factor (TNF) signaling pathway, thyroid hormone signaling pathway, T cell receptor signaling pathway and other pathways. The results of molecular docking showed that the binding energy of all compounds to protein was less than -5.6 kcal/mol, indicating that each compound and each protein could bind well.Conclusions:Bielong Ruangan decoction participates in the treatment of liver cancer through " multi-component, multi-target and multi-channel" ways, and plays an anti-cancer role mainly by regulating the proliferation and invasion of tumor cells and tumor inflammatory microenvironment.

Effects of primary location of colorectal cancer on surgical outcome of liver metastases / 中国基层医药

Objective:To analyze the effects of the primary location of colorectal cancer on the surgical outcome of liver metastases.Methods:A cross-sectional study was conducted on 178 patients with liver metastases from colorectal cancer admitted to Binzhou Central Hospital from January 2012 to January 2022. According to whether the patients had recurrence after surgery, they were divided into a recurrence group ( n = 88) and a control group ( n = 90). The general and clinical data were compared between the two groups. Logistic multivariate analysis of the factors with statistical significance was further performed to identify the risk factors of postoperative recurrence of liver metastases from colorectal cancer after surgery. The correlation between the primary location of colorectal cancer and each risk factor was analyzed. The recurrence of colorectal cancer was compared anong patients with different primary locations of colorectal cancer at 12 months after surgery. Results:Primary location at the right colon [55.68% (49/88), lymph node metastasis [92.05% (81/88)], D-dimer ≥ 180 μ g/L, albumin < 29 g/L, ineffective/no neoadjuvant chemotherapy [43.18% (33/38)], and high-risk clinical risk score [53.41% (47/88)] were risk factors for postoperative recurrence of liver metastases from colorectal cancer after surgery ( P = 0.024, 0.019, 0.001, 0.028, < 0.001, 0.001). The primary location of colorectal cancer was positively correlated with lymph node metastasis, D-dimer, and clinical risk score ( P = 0.043, 0.046, 0.030), and negatively correlated with albumin and the efficacy of neoadjuvant chemotherapy ( P = 0.004, 0.033). In 178 patients, the recurrence rate of liver metastases from colorectal cancer at 3 months [53.57% (15/70)], 6 months [55.17% (32/70)], and 12 months [55.68% (49/70)] was significantly higher in the right colon compared with the left colon [32.14% (9/40), 24.14% (14/40), 26.14% (23/40) and the rectum [14.29% (4/68), 20.69% (12/68), 18.18% (16/68)] ( χ2= 4.73, 7.85, 6.27, all P < 0.05). Conclusion:Right colon, lymph node metastasis, D-dimer, albumin, neoadjuvant chemotherapy efficacy, and clinical risk score are the risk factors for postoperative recurrence of liver metastases from colorectal cancer. Patients with the primary location at the right colon have a higher postoperative recurrence rate.

General data and biochemical indicators were collected. The Kruskal-Wallis test was performed to compare the measurement data among groups. The chi-squared test was performed to compare the count data among groups. Spearman's correlation (bivariate) was performed. Binary logistic regression was performed to analyze the influential factors of liver cancer. Results:There were significant differences in the levels of total cholesterol (TC), triacylglycerol (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) among the three groups ( F = 32.14, 27.59, 10.88, 34.09, all P < 0.05). TC and LDL-C levels in the hepatitis B-related liver cancer group were significantly higher than those in the hepatitis B cirrhosis group ( F = -32.31, -50.19, both P < 0.05). There were no significant differences in TG and HDL-C levels between hepatitis B-related liver cancer and hepatitis B cirrhosis groups ( F = -10.69, 4.46, both P > 0.05). TC, TG, HDL-C and LDL-C levels in the hepatitis B cirrhosis group were significantly lower than those in the chronic hepatitis B group ( F = 53.30, 46.98, 24.61, 48.57, all P < 0.05). LDL-C level was positively correlated with the occurrence of liver cancer ( r = 0.20, P < 0.05). HDL-C level was negatively correlated with the occurrence of liver cancer ( r = -0.15, P < 0.05). LDL-C was an independent risk factor for liver cancer ( OR = 3.35, P < 0.05), and HDL-C was a protective factor for liver cancer ( OR = 0.12, P < 0.05). Conclusion:Compared with patients with chronic hepatitis B and hepatitis B cirrhosis, patients with hepatitis B-related liver cancer had abnormal peripheral blood lipid levels, which may be related to the abnormal lipid metabolism of tumor cells. Moreover, peripheral blood lipid levels may affect the occurrence and development of tumor cells.
