Objective To systematically review the efficacy and safety of laparoscopic hepatectomy (LH) and open hepatectomy (OH) for patients with hepatocellular carcinoma (HCC). Methods PubMed, EMbase, The Cochrane Library, CBM, WanFang Data, CNKI databases were electronically searched to collect the case-control studies about LH vs. OH for patients with HCC from inception to December, 2015. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then meta-analysis was performed by using RevMan 5.3 software. Results A total of 28 studies involving 1 908 patients were included. The results of meta-analysis showed that: the LH group was superior to OH group on complications (OR=0.35, 95%CI 0.26 to 0.48, P<0.000 01), hospital stay (MD=–4.18, 95%CI (–5.08, –3.29),P<0.000 01), and five years overall survival rate (OR=1.65, 95%CI 1.23 to 2.19,P=0.000 7) and disease-free survival rate (OR=1.51, 95%CI 1.12 to 2.03, P=0.006). However, no significant differences were found in one year and three years overall survival rate, disease-free survival rate, and postoperative recurrence rate. Conclusion Current evidence shows that the LH is superior to OH for the treatment of HCC, and may be amenable to surgery because of its safety and longtime efficacy. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify above conclusion.
ObjectiveTo study the relationship between expression of p27KIP1 and progression of hepatocellular carcinoma(HCC).MethodsThe expression of p27KIP1 in 52 cases of HCC was detected by immunohistochemistry of strept avidinbiotin complex and mRNA in situ hybridization.ResultsThe positive cells of p27KIP1 protein were diffused in HCC.The positive signal was localized in nuclei.The labeling index (LI) of p27KIP1 protein was significantly higher in tumorsurrounding tissues than that in tumor tissues. p27KIP1 protein LI showed a positive correlation with the differentiation grade of HCC.The better differentiation of cancer cells, the higher LI of p27KIP1 protein (P＜0.01).The positive cells of p27KIP1 mRNA were also diffused in HCC.The positive signal was localized in nuclei and cytoplasm. As to the expression of p27KIP1 at the mRNA level,there was no significant correlation with tumorsurrounding tissues and stages of HCC.Conclusionp27KIP1 protein is associated with progression and differentiation grade of hepatocellular carcinoma.
Objective To summarize the relation between various kinds of immune cells infiltration in tumor microenvironment and prognosis of hepatocellular carcinoma (HCC). Method Literatures on the relation between immune cell infiltration in tumor microenvironment and prognosis of HCC in recent years were collected and reviewed. Results The immune cell infiltration in the tumor microenvironment of HCC was inextricably linked with the progression of HCC. CD4+ T cells, CD8+ T cells, M1 macrophages, B cells, and memory T cells might be associated with a good prognosis in patients with HCC, while regulatory T cells, regulatory B cells, and M2 macrophages might be related to the poor prognosis of patients with HCC. Conclusion The study of immune cell infiltration in HCC can provide new ideas for precise immunotherapy of HCC.
Objective To clarify relationship between signal heterogeneity on hepatobiliary phase of gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced MRI and prognosis of hepatocellular carcinoma (HCC). Methods From January 2014 to January 2017 in the First Affiliated Hospital of Chongqing Medical University, a total of 77 patients with the pathologically proved HCC underwent Gd-EOB-DTPA-enhanced MRI prior to surgery were included in this study. On the basis of the signal heterogeneity in the hepatobiliary phase, the included patients were designed to homogeneous hypointensity group and heterogeneous hyperintensity group. The disease-free survival time were compared between the 2 groups and it’s influencing factors were analyzed. Results Seventy-seven patients with HCC were included, including 45 cases of homogeneous hypointensity and 32 cases of heterogeneous hyperintensity. There were no significant differences in the age, gender, etiology, liver function, alpha-fetoprotein, differentiated degree, Child-Pugh grade, lesion diameter, lesion border, and number of lesions between the 2 groups (P>0.05). However, the HCC patients with heterogeneous hyperintensity had a later BCLC staging (P=0.001). The disease-free survival time of the patients with homogeneous hypointensity and heterogeneous hyperintensity was (17.0±9.8) months and (12.4±10.4)months, respectively. The Kaplan-Meier survival curve showed that the disease-free survival time in the patients with homogeneous hypointensity was significantly better than that in the patients with heterogeneous hyperintensity (P=0.020). The results of univariate analysis showed that the other confounding factors had no effect on the disease-free survival time of patients with hepatocellular carcinoma (P>0.05) except for the signal of hepatobiliary phase (P<0.05). Furthermore, the hepatobiliary phase signal, BCLC stage, and degree of differentiation, which might be clinically considered as potentially influencing for the prognosis of patients with HCC, were included in the Cox multivariate proportional hazard regression model and found that the heterogeneous hyperintensity was still the risk factor of the disease-free survival rate in patients with HCC (P=0.047). Conclusion Signal heterogeneity on hepatobiliary phase of Gd-EOB-DTPA-enhanced MRI is related to prognosis of patients with HCC, heterogeneous hyperintensity may indicate a lower disease-free survival rate.
ObjectiveTo explore the mechanism of postoperative recurrence of hepatocellular carcinoma(HCC) and predicting the candidate drug.
