ObjectiveTo evaluate the effects of combined TACE and PVC regarding the survival and diseasefree survival rate in hepatocellular carcinoma (HCC) patients. MethodsThe relevant articles were searchd by a database search of PubMed, EMBASE, Cochrane Library (CENTRAL) Databases, Web of Science, Sciencedirect, National Institute of Health Clinical Trials Database, CNKI, WANFANG Database, and VIP Database. The analysis of the data was performed using Revman 5.1 Software. ResultsBy searching and selecting, a total of ten articles met the inclusion criteria, of which 6 were in the postoperative group, and 4 were in the no-operative group. There were no statistical significance of heterogeneity in each group through subgroup analyzed. The pooled OR showed that combined TACE and PVC could significantly increase the 1-, 2-, and/or 3-year survival and disease-free survival rates compared with TACE alone for HCC patients. The pooled OR and 95% CI of the 1-, 2-and/or 3-year survival and disease-free survival rate, respectively, were as follows:In operative group, 1-year disease-free survival rate 2.09, 1.21-3.61; 3-year disease-free survival rate 3.62, 1.88-6.97; 1-year survival rate 2.25, 1.30-3.87; 3-year survival rate 1.96, 1.20-3.21. In no-perative group:1-year survival rate 3.90, 2.33-6.54; 2-year survival rate 5.30, 1.87-15.06. Conlusions Compared with TACE alone, postoperative adjuvant combined TACE and PVC can significantly increase the 1-, and 3-year survival and disease-free survival rates. For no-perative group, adjuvant combined TACE and PVC can significantly increase the 1-, and 2-year survival rates. Based on the limitations of this meta-analysis (this article is included in the high quality literature less), clinicians should be cautious by using our findings.
Objective To summarize the blood supply to the sources and characteristics of advanced breast cancer，and explore the method，efficacy，and clinical applications of preoperative super-selective arterial catheterization chemoembolization under DSA for it. Methods Sixty patients with advanced breast cancer confirmed by the aspiration biopsy from February 2007 to October 2011 in this hospital were selected. Seldinger method was used，distributing of the tumor blood supply artery was identified and intubated the target artery by super-selective arterial catheterization via the femoral artery puncture under the DSA. Then，pirarubicin 60 mg plus paclitaxel 120 mg of two chemotherapy drugs was injected into slowly the target artery and the intervention infusion chemotherapy was performed，finally the tumor blood supply artery was embolizated by gelatin sponge particle. Results A total of 112 conclusive blood supply artery in 60 patients with DSA were found，including eight cases of single blood supply artery，52 cases of multiple blood supply arteries，mainly in the lateral thoracic artery and （or） internal thoracic artery-based. The complete remission rate was 25.0% （15/60），partial remission rate was 73.3% （44/60），stable disease rate was 1.7% （1/60），the total effective rate was 98.3% （59/60）. There was no progression disease. The median remission duration was 19 months，median survival time was 40 months. Conclusions The location of the original foci of breast cancer is closely related to blood supply arteries. The tumor in the lateral of the breast mainly dominates by the lateral thoracic artery blood supply. The tumor in the inner breast mainly dominates by the internal thoracic artery blood supply. The preoperative super-selective arterial catheterization chemoembolization under DSA can obviously improve the therapeutic effect，long-term survival，and the target of interventional chemoembolization.
ObjectiveTo explore the effect of hydroxyapatite nanoparticle (nHAP) on hepatocellular carcinoma (HCC) and its mechanisms. MethodsThe literatures about the effect of nHAP on HCC were reviewed and summarized. ResultsAs a new nanoparticle, nHAP could suppress the DNA synthesis and subsequent division and proliferation of HCC cells through the inhibition of proliferating cell nuclear antigen (PCNA) and telomerase gene expression and increase of intracellular Ca2+. Moreover, nHAP was able to suppress the differentiation and metastases of HCC cells through the effect on the expressions of Paxillin and P130cas and the decrease of expressions of multiple drug resistance gene protein, microvessel density, and vascular endothelial growth factor. Finally, nHAP induced the apoptosis of HCC tumor cells by the regulation of bcl-2 and bax protein expressions. The combined use of nHAP and chemoembolization drugs could enhance the efficacy, prolong drug duration and reduce toxicity. ConclusionnHAP can inhibit the division, proliferation, differentiation, and metastases, and promote the apoptosis of HCC cells and combined use with chemoembolization drugs can enhance the efficacy and reduce toxicity.
The treatment of liver cancer is still a challenge in the world, and it is mainly refers to hepatocellular carcinoma (HCC). There are many factors affecting the overall survival rate of HCC; the recurrence of HCC is the main risk factor affecting the survival of patients, hence, it is urgent to explore the clinical treatment of recurrent HCC to obtain long-term survival of the patients. Up to now, surgical treatment is a radical treatment for HCC. Similarly, liver resection and liver transplantation are still the main therapy methods for recurrent HCC. In addition, radiofrequency ablation and transcatheter arterial chemoembolization and other local treatments still play an irresistible role. Therefore, emphasizing the postoperative follow-up of patients, diagnosing recurrent HCC in early stage, paying attention to the risk factors of HCC recurrence and selecting a suitable treatment plan for individuals are critical ways to prolong the survival of patients.
Objective To investigate the growth of tumors and the natural life length of the rats after the adriamycinethylcellulose microspheres(ADM-EC mc) were injected in the rats bearing transplantable liver cancer through their hepatic arteries.Methods ADM-EC mc were infused into the proper hepatic arteries of the Wistar rats (W256). All of the rats were divided randomly into five groups, group 1: control, group 2: normal saline, group 3: conventional ADM, group 4: placebo ethylcellulose microspheres, and group 5: ADM-EC mc. Results As compared with other four groups, the ADM-EC mc (group 5) showed the best inhibition of the growth of tumors and the longest mean life length of the rats. Conclusion Hepatic arterial infusion of ADM-EC mc can inhibit the growth of the tumor, aggravate the necrosis, and improve the effects of the chemotherapy of liver cancer.
ObjectiveTo systematically review the efficacy and safety of transcatheter arterial chemoembolization (TACE) combined with sorafenib and TACE only treating the intermediate or advanced hepatocellular carcinoma (HCC) in Chinese people. MethodsThe PubMed, Embase, Cochrane Library, CBM, CNKI, VIP, and Wanfang Data for randomized controlled trials (RCT) on TACE combined with sorafenib (TACE combined with sorafenib group) and TACE (TACE alone group) from inception to December 2014 were searched. The literatures and data were screened and extracted. The meta analysis was performed using RevMan 5.1 software. ResultsSix RCTs involving 498 patients with HCC were included. The results of meta analysis showed that the objective response rate[OR=2.28, 95% CI (1.52-3.42), P < 0.000 1] and the disease control rate[OR=6.62, 95% CI (4.12-10.65), P < 0.000 01] were higher, the 1-year survival rate[OR=3.27, 95% CI (2.06-5.22), P < 0.000 01] and 2-year survival rate[OR=4.55, 95% CI (2.28-9.07), P < 0.000 1] were longer, the safety and tolerability of adverse reactions were better in the TACE combined with sorafenib group as compared with the TACE alone group. ConclusionsIn Chinese people, compared with TACE alone group, TACE combined with sorafenib group have higher objective response rate, disease control rate, 1-year survival rate, and 2-year survival rate. However, due to the lower quality of included literatures, these conclusions should be treated cautiously.
Objective To explore the value of iodine overlay image technique based on dual-source CT dual-energy for the diagnosis in the primary hepatocellular carcinoma patients undergoing transcatheter arterial chemoembolization (TACE). Methods The imaging data of patients with primary hepatocellular carcinoma after TACE treatment from September 2015 to November 2018 were retrospectively analyzed. All patients completed dual-source CT dual-energy examination and digital subtraction angiography (DSA). The imaging data of the patients were analyzed by conventional linear blending images and iodine overlay image. The results of DSA were taken as the gold standard. The data indexes measured by the two imaging methods were compared. The consistency between the two imaging methods and DSA was determined by Kappa statistics. Results A total of 31 patients were included, and 57 nodes were found under DSA examination. The image quality evaluation (P<0.05), sensitivity (95.35% vs. 69.77%), specificity (92.86% vs. 64.29%), accuracy (94.74% vs. 68.42%), positive predictive value (97.62% vs. 85.71%) and negative predictive value (86.67% vs. 40.91%) of iodine overlay images were higher than those of conventional linear blending images. The consistency between conventional linear blending images and DSA was low (Kappa=0.286, P=0.023), and the consistency between iodine overlay images and DSA was excellent (Kappa=0.861, P<0.001). Conclusions Iodine overlay image could avoid the iodide artifact effectively and evaluate the abnormal enhancement quantitatively and qualitatively in patients undegoing TACE. This method could obtain more information to help diagnose in clinical and evaluate the postoperative efficacy of TACE accurately and objectively.
【Abstract】Objective To investigate the change of vascular endothelial growth factor (VEGF) expression in HepG2 cells under hypoxia. Methods HepG2 cells were cultured under hypoxia（hypoxia group） and normal condition (control group). VEGF expression of HepG2 cells was examined by immunohistochemical staining. The growth of HepG2 cells was examined by MTT colorimetry and cell count. VEGF level in the culture medium was measured by ELISA.Results After 48 h and 72 h of culture, the growth rate of HepG2 cells in hypoxia group was lower than that in control group (P＜0.05). The cell count in hypoxia group (2.51×104/μl and 2.69×104/μl, respectively) was much lower than that in control group(3.01×104/μl and 3.52×104/μl) after 48h and 72h of culture (P＜0.05). In hypoxia group, VEGF level in the culture medium after 24 h and 48 h was higher than that in control group (P＜0.05, P＜0.01). Conclusion Hypoxia may enhance the VEGF expression in HepG2 cells and this could be the reason of high expression of VEGF after transcatheterized hepatic arterial chemoembolization.
