ObjectiveTo explore the combined application of neutrophil to lymphocyte ratio (NLR) and systemic immune inflammation index (SII) on the prognosis of hepatitis B-related hepatocellular carcinoma after resection.MethodsRetrospectively collected data of 180 patients with hepatitis B-related hepatocellular carcinoma who were hospitalized in the Department of Infectious Diseases and Hepatobiliary Surgery of the Affiliated Hospital of Southwest Medical University and received surgical treatment from January 2013 to December 2019, including general information, laboratory examination and abdominal CT or MRI results. NLR and SII values were measured at one week before operation, and their critical values of NLR and SII were determined by ROC curve analysis. Univariate and multivariate analysis were performed to determine the risk factors to predict the survival status of patients with hepatitis B-related hepatocellular carcinoma after hepatectomy.ResultsUnivariate analysis showed that AFP, platelets, TNM staging, portal vein tumor thrombus, tumor differentiation, NLR, SII, and NLR+SII combined score were significantly correlated with the prognosis of patients with hepatitis B-related hepatocellular carcinoma (P<0.05). Multivariate analysis showed that PLT [HR=1.791, 95%CI (1.124, 2.854), P=0.014], NLR [HR=4.289, 95%CI (2.571, 7.156), P<0.001], SII [HR=5.317, 95%CI (3.016, 9.374), P<0.001], and NLR+SII combined score [HR=7.901, 95%CI (4.124, 15.138), P<0.001] were independently correlated with the survival of patients with hepatitis B-related hepatocellular carcinoma.ConclusionsThe preoperative NLR+SII combined score can be used to evaluate the postoperative prognosis of patients with hepatitis B-related hepatocellular carcinoma. The higher the score, the lower the postoperative survival rate.
ObjectiveTo explore expressions of the metaherin (MTDH) mRNA and its protein in hepatitis B related hepatocellular carcinoma tissues and its clinical significance. MethodsSeventy two tissues of patients with hepa-titis B related hepatocellular carcinoma who were treated in Affiliated Taihe Hospital of Hubei Medical University from Jul. 2012 to Oct. 2013 were collected retrospectively. Quantitative PCR (Q-PCR) and Western blot methods were used to detect the expression levels of MTDH mRNA and its protein in 10 cases of hepatitis B related hepatocellular carcinoma tissues and pericarcinoma tissues. Besides, immunohistochemistry was used to determine the expression of MTDH protein in 72 cases of hepatocellular carcinoma tissues, then the relationship of expression of MTDH protein and clinico-pathological features was explored. ResultsThe expression levels of MTDH mRNA and its protein in hepatocellular carcinoma tissues were both higher than those of pericarcinoma tissues (8.50±0.84 vs. 4.55±0.81, t=10.797, P=0.000; 0.65± 0.24 vs. 0.25±0.16,t=6.375, P=0.013). The MTDH protein was positively expressed in 42 cases (58.3%) and negatively expressed in 30 cases (41.7%) of hepatocellular carcinoma tissues. The results of logistic regression showed that,MTHD protein was up-regulated in patients with category Ⅲ of Edmondson grade (OR=4.783, 95% CI:2.663-11.918, P=0.020), microvascular invasion (OR=37.790, 95% CI:2.227-99.434, P=0.005), and lymph node metastasis (OR=7.332, 95% CI:3.325-30.669, P=0.023). ConclusionExpressions of MTDH mRNA and its protein are both higher in hepatitis B related hepatocellular carcinoma tissue, which are correlated with poor prognosis.
Objective To evaluate the efficacy of transcatheter arterial chemoembolization (TACE) combined with radiofrequency ablation (RFA) in treating primary hepatocellular carcinoma (HCC). Methods From March 2004 to March 2006, 137 patients with primary HCC underwent TACE alone (n=87) and TACE+RFA (n=50), respectively, after the interventional treatment, all patients periodically received CT reexaminations and alpha fetoprotein (AFP) measurement. The therapeutic efficacy, AFP level and survival rate between two groups were compared with each other. Results In TACE group the effective rate (CR+PR) was 34.5%, AFP decreasing amplitude was 54.2%, and 2 years survival rate was 43.7%. While in TACE+RFA group, the effective rate (CR+PR) was 70.0%, AFP decreasing amplitude was 78.0%, and 2 years survival rate was 62.0%, there were significant differences between two groups (P＜0.05). Conclusion Combined application of TACE and RFA is significantly superior to TACE alone in treatment of primary HCC.
ObjectiveTo introduce the basic principles of commonly used assessment methods for liver function reserve, and compare the advantages and disadvantages of various assessment methods, so as to provide a reference for hepatectomy of patients with hepatocellular carcinoma (HCC). MethodThe literature on evaluation methods of liver reserve function in patients with HCC at home and abroad in recent years was searched and summarized. ResultsFrom the results of literature review, the Child‐Pugh score and indocyanine green discharge test were the most commonly used to assess preoperative liver function reserve for patients with HCC. The application value of other examinations such as albumin-bilirubin score, gadolinium-ethoxybenzyl diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging (Gd-EOB-DTPA-enhanced MRI), nuclear medical imaging in predicting post-hepatectomy liver failure was gradually being explored. ConclusionsThe combination of clinical parameters and volumetric studies is used to assess preoperative liver function reserve for patients with HCC. The clinical applications of nuclear medical imaging and Gd-EOB-DTPA-enhanced MRI make up for the deficiency of local liver function reserve evaluation, which are important examinations to assess liver function reserve after conversion therapy in the future. However, more domestic studies are still needed to confirm their values.
ObjectiveTo study the clinical value of changes of serumα-fetoprotein(AFP) and soluble cell adhesion molecule-1(sICAM-1) levels before and after surgical treatment of primary hepatocellular carcinoma(PHC) as predictors of patient survival. MethodsThe clinical data and followed-up results of 86 patients with hepatocellular carcinoma received hepatectomy or radiofrequency ablation(RFA) in Xijing Hospital and the 451st Hospital of PLA were retrospectivly analyzed. The changes of peripheral blood AFP and sICAM-1 levels in patients before and in 1 month after treatment were observed and all patients were divided into different groups according to the changes in both two markers. Then survival rates of each group were analyzed. ResultsThe patients with AFP < 20μg/L or sICAM-1 < 1 000 U/L before treatment had lower tumor recurrence rate and higher survival rate than patients with elevated serum levels of the both markers(AFP:P=0.018, P < 0.001;sICAM-1:P=0.027, P < 0.001). The larger tumor, late TNM stage, and higher rate of recurrence were associated with elevated serum levels of the both markers(AFP:P=0.016, P=0.026 and P=0.025;sICAM-1:P < 0.001, P=0.024 and P=0.032). The better survival situation was closely related with these cases treated with hepatectomy and their levels of both markers were lower than the above cutoff values both before and after treatment, or leves of both markers above the cut-off values returned to within the normal range after treatment (AFP:P=0.006, P=0.001;sICAM-1:P=0.001, P=0.002). The patients who had simultaneous increase of AFP and sICAM-1 after operation showed the worst tumor-free and overall survivals(P=0.007, P < 0.001). ConclusionTo test the changes of serum AFP and sICAM-1 levels in early stage after treatment for patients who received radical resection of hepatocellular carcinoma has good clinical value for monitoring of tumor recurrence and predict prognosis.
ObjectiveTo explore the predictive value of preoperative serum heat shock protein 90α (HSP90α) level in combination with the prognostic nutritional index (PNI) for patients with hepatocellular carcinoma (HCC) after transarterial chemoembolization (TACE). MethodsThe HCC patients confirmed by histopathological examination and underwent TACE at Guigang People’s Hospital from January 2022 to June 2023 were as the observation group, the healthy individuals who underwent physical examinations during the same period and same hospital as the control group. The blood before treatment and on the day of the physical examination was collected to detected the HSP90α and albumin levels, as well as lymphocyte count. The PNI was calculated [PNI=albumin (g/L)+5×lymphocyte count (×109/L)]. The clinical outcome (tumor progression or death) was observed within one year after TACE treatment, those without tumor progression or death were defined as a good prognosis, while those with tumor progression or death were defined as a poor prognosis. Using the multivariate unconditional logistic regression analysis to identify the risk factors affecting the poor prognosis for HCC patients, and the receive operating characteristic (ROC) curve to evaluate the predictive value of serum HSP90α level in combination with PNI in distinguishing prognosis after TACE treatment.ResultsIn this study, there were 178 cases in the observation group and 100 cases in the control group. The serum HSP90α level (μg/L) in the observation group was higher than that in the control group (96.40±33.57 vs. 52.19±22.13, t=3.191, P<0.001), and the PNI value was lower than that in the control group (43.70±5.24 vs. 56.46±6.86, t=–16.144, P<0.001); Within one year after TACE treatment, there were 70 patients with poor prognosis and 108 patients with good prognosis. The serum HSP90α (μg/L) level in the patients with poor prognosis was higher than that in the patients with good prognosis (117.33±29.48 vs. 82.83±28.84, t=7.726, P<0.001), and the PNI was lower than that in the control group (40.49±4.18 vs. 45.78±4.80, t=–7.548, P<0.001). The multivariate unconditional logistic regression analysis found that the probabilities of incidence of poor prognosis after TACE treatment were higher in the patients with Chinese liver cancer staging Ⅲa–Ⅲb stage [reference: Ⅰ–Ⅱa stage, OR (95%CI)=5.332 (1.058, 26.875), P=0.043] and increased age and HSP90α level [OR (95%CI)=1.100 (1.025, 1.180), P=0.008; OR (95%CI)=1.049 (1.029, 1.070), P<0.001] , as well as decreased PNI value [OR (95%CI)=0.772 (0.686, 0.869), P<0.001]. The area under the ROC curve after TACE treatment in the HCC patients by serum HSP90α level in combination with PNI was 0.878 [95%CI=(0.820, 0.922)] in differentiating poor prognosis or not. ConclusionThe analysis results of this study suggest that preoperative serum HSP90α level in combination with PNI has a higher predictive value for prognosis of HCC patients after TACE treatment.
Objective To investigate the feasibility of elective laparoscopic hepatectomy in the treatment of ruptured hepatocellular carcinoma. Methods We tried to perform an elective laparoscopic hepatectomy for a middle-aged man who had a ruptured hepatocellular carcinoma without active hemorrhage. The data of this patient was summarized. Results The patient received the elective laparoscopic hepatectomy, and the liver lesions were completely removed. The operation was successful. Operative time was 300 min and intraoperative bleeding was 500 mL. Postoperative recovery of this patient was good and no complication occurred. The abdominal drainage tube was removed on 4 days after operation, and he discharged on 8 days after operation. The pathology confirmed that the hepatocellular carcinoma was moderately differentiated and ruptured. Conclusion Elective laparoscopic hepatectomy is safe and feasible in the treatment of ruptured hepatocellular carcinoma for specific patient, but this operation needs to be performed by experienced surgeons with laparoscopic skills.
ObjectiveTo summarize the application research progress of animal models of hepatocellular carcinoma at home and abroad in recent years. MethodThe relevant literature on animal models of hepatocellular carcinoma at home and abroad in recent years was reviewed. ResultsAt present, the common animal models of hepatocellular carcinoma mainly included spontaneous animal model, induced animal model, gene modified animal model, transplanted animal model, and humanized animal model. The etiology, pathogenesis, and pathophysiological changes of various animal models were different. The selection of animal models of hepatocellular carcinoma depended on the type and purpose of research. ConclusionsVarious animal models of hepatocellular carcinoma have their own advantages and disadvantages. Researchers should choose different animal models according to their own research purposes to achieve the expected experimental purposes, so that more valuable research results of animal models of hepatocellular carcinoma can be applied to clinical practice, and finally these research results can be truly applied to diagnosis and treatment of hepatocellular carcinoma.
ObjectiveTo observe the changes of peripheral blood lymphocyte subsets of patients with primary hepatocellular carcinoma (PHCC) treated with radiofrequency ablation (RFA). MethodsThe data of 70 cases of hospitalized patients with PHCC that voluntary accepted RFA diagnosed by clinical and pathological in our hospital between July 2011 and December 2014 were collected. According to the numbers of HCC lesions, 70 cases were divided into single focus group (n=41) and multifocal group (n=29). The changes of their immune parameters before and after RFA were analyzed. Results①The ratioes of peripheral blood CD3+/CD19-, CD3+/CD4+, CD4+/CD8+, and NK cells on 7 days and 14 days after RFA treatment of 70 cases were significantly higher than those on 1 day before RFA treatment (P < 0.05). The ratio of CD3+/CD8+ T cells reduced from 1 day before RFA treatment to 14 days after RFA treatment, but the difference was no statistically significant (P > 0.05).②The changing trend of peripheral blood lymphocyte subsets before and after RFA treatment in single focus group and multifocal group were similar to the above.③Compared with single focus group, the ratioes of peripheral blood CD3+/CD19-, CD3+/CD4+, CD4+/CD8+, and NK cells before and after RFA treatment in multifocal group were lower, and the ratio of CD3+/CD8+ T cells was higher, but the difference were not statistically significant (P > 0.05). ConclusionRFA can not only destroy small PHCC foci, but also to significantly improve immune function and enhance the anti-tumor effect.
ObjectiveTo investigate the role of Peptidase domain containing associated with muscle regeneration 1 (PAMR1) in the proliferation, migration, and prognosis of hepatocellular carcinoma (HCC) through cellular experiments and clinical sample validation. Methods① Bioinformatics analysis was performed on datasets from the GEO public database to identify and screen for key genes, ultimately selecting PAMR1 for further study. Findings were validated using data from the TCGA database and six primary HCC surgical specimens prospectively obtained from the Army Characteristic Medical Center of Army Medical University from February 2024 to June 2024. ② PAMR1-overexpressing cell lines were established using HCC cell lines Huh7 and Lm3. Cells were transfected with either the recombinant plasmid pcDNA3.1(+)-PAMR1 as overexpression group or the empty vector pcDNA3.1(+) as negative control group. The effects of PAMR1 on HCC cell proliferation and migration were assessed using the Cell Counting Kit-8 (CCK-8) assay and wound healing assay, respectively. ③ Pathological specimens and clinical data were retrospectively collected from 61 patients with primary HCC who underwent surgical resection at the Army Characteristic Medical Center of Army Medical University between May 2019 and April 2020. The impact of PAMR1 expression on disease-free survival was evaluated. Results① PAMR1 was identified as a candidate gene through GEO database screening and was found to be downregulated in HCC tissues based on both TCGA data and the six HCC surgical specimens. ② The CCK-8 assay revealed that cell proliferation was significantly inhibited in the PAMR1 overexpression group compared to the negative control group (P<0.05). Similarly, the wound healing assay demonstrated reduced migratory capability in PAMR1 overexpression group (P<0.05). ③ Multivariate cox proportional hazards regression analysis of patient data indicated that high PAMR1 expression serves as an independent protective factor for disease-free survival in HCC (HR= 0.335, P=0.026). ConclusionPAMR1 serves as a crucial gene in HCC, high PAMR1 expression can significantly suppressing tumor cell proliferation and migration and indicates a favorable prognosis.
