  • Effectiveness and Safety of TACE Combined with AHCS for Primary Hepatic Carcinomas: A Systematic Review

    Objective To evaluate the clinical effectiveness and safety of transcatheter arterial chemoembolization (TACE) combined with argon-helium cryotherapy system (AHCS) for primary hepatic carcinomas (PHC), and to provide references for clinical practice and research. Methods Such databases as The Cochrane Library, PubMed, EMbase, Web of Science, CBM, CNKI, VIP and WanFang Data were searched, and other sources like the relavant references were also retrieved to collect the randomized controlled trials (RCTs) about TACE combiend with AHCS for PHC published by May 1st, 2012. After literature screening, data extraction and quality evaluation performed by two reviewers independently according to the inclusion criteria, the meta-analysis was conducted using RevMan 5.1 software. Results A total of 16 RCTs involving 1 467 patients were included. The results of meta-analysis showed: a) The TACE+AHCS group was superior to the TACE alone group in total effective rate, complete necrosis rate, 0.5-, 1-, 1.5-, 2- and 2.5-year survival rates, AFP, CD4 and Th/Ts cells, and there were significant differences (Plt;0.05); and b) The TACE+AHCS group was superior to the AHCS alone group in 0.5-, 1.5-, 2- and 2.5-year survival rates, AFP and Th/Ts cells, and there were significant differences (Plt;0.05). Conclusion Compared with the TACE or AHCS alone, TACE combined with AHCS can improve long-term survival rate and short-term curative effect, and improve PHC patients’ immunity. However, its long-term curative effect and safety still needs to be further verified by more large sample and high quality RCTs.

  • Application of Three-dimensional CT Angiogram in Perioperative Evaluation for Patients Underwent Transapical Aortic Valve Implantation——The Initial Experience from West China hospital

    ObjectiveTo introduce the role of three dementional computed tomograph (3D-CT) for patients underwent transcatheter aortic valve implantation (TAVI) procedure in perioperative evaluation. MethodsFrom April 2014 to June 2015, we retrospectively analyzed clinical data of 28 patients with severe aortic stenosis underwent successful TAVI procedure using new second-generation device, who were enrolled in this study including 12 males and 16 females at mean age of 72.8±4.5 years. We used 3D-CT to get the perioperative relative evaluation, including valve morphology and calcification degree, annular diameter, aoronary ostium height, ascending aorta, aortic sinus diameter, left ventricular-aortic angle, optimal intraoperative angiogram projection angle. Based on the evaluation by 3D-CT image, the prosthesis size, balloon size, best intraoperative imaging projection angle and approach of apex were then chosen. ResultsAll patients with severe aortic stenosis underwent successful TAVI procedure with mean logistic Euro-SCORE I:26.2%±7.9%. CT image revealed that mean aortic annular diameter was 24.6±1.8 mm with mean valve prosthesis size 25.8±1.1 mm and pre-dilation balloon size 23.1±1.2 mm and 76.8% patients were of tricuspid aortic valve with severe calcification and 25% patients were of asymmetric calcification. Optimal intraoperative angiogram image was achieved in 92.9% patients with the help of preoperative CT image. There was a statistic difference in mean transvalvular gradient after valve implantation (54.1±15.3 mm Hg vs. 13.1±8.5 mm Hg, P<0.05). And there was no mortality or severe complication postoperatively. Conclusion3D-CT image palys an important role during perioperative evaluation of TAVI procedure and it can be helpful for Chinese doctors to operate TAVI successfully.

  • Traditional Chinese Medicine plus Transcatheter Arterial Chemoembolization for Unresectable Hepatocellular Carcinoma: A Meta-analysis of Randomized Controlled Trials

    Objective To evaluate the effectiveness and safety of traditional Chinese medicine (TCM) plus transcatheter arterial chemoembolization (TACE) compared with TACE alone, in the treatment of unresectable hepatocellular carcinoma (HCC). Methods The Cochrane Library, MEDLINE, EMBASE, CANCERLIT, CBM, CNKI and VIP were searched electronically. Relevant journals and conference proceedings were also handsearched. The quality of included studies was assessed according to the criteria recommended by the Cochrane Handbook for Systematic Reviews of Interventions, and meta-analyses were performed for homogeneous studies using The Cochrane Collaboration’s RevMan 4.2.10 software. Subgroup analyses by frequency of TACE (lt;3 or ≥3 times) were also performed. Results Thirty seven trials, all published in China, involving 2 653 participants were included. The quality of 2 studies was graded B (medium) and that of the other 35 was graded C (low). Meta-analyses showed that TCM plus TACE, compared with TACE alone, could significantly improve survival, tumor response (complete and partial), quality of life and clinical symptoms, and was also associated with a lower incidence of adverse reactions. Subgroup analyses indicated that, patients with less than three TACE had more significant improvement in survival and clinical symptoms, while patients with three or more TACE had more significant improvement in tumor response and quality of life. The incidence of adverse reactions was similar between these two different frequencies of TACE. Conclusions The treatment regimen of TCM plus TACE is superior to TACE alone in patients with unresectable HCC. As the existing data have a high risk of bias, the current evidence is insufficient to define the efficacy of the combination treatment, and further large-scale, high-quality randomized controlled trials are needed.

  • TACE Combined with Thermotherapy for Primary Hepatic Carcinoma: A Meta-Analysis

    Objective To evaluate the clinical efficacy and safety of transcatheter arterial chemoembolization (TACE) combined with thermotherapy for primary hepatic carcinoma (PHC), and to provide references for clinical practice and research. Methods The following databases as The Cochrane Library, PubMed, EMbase, CBM, CNKI, VIP and WanFang Data were searched electronically, and the other sources as supplying, such as tracing related references, were also retrieved. Besides, some unknown information was also obtained by communicating with other authors. All randomized controlled trials (RCTs) on TACE combined with thermotherapy versus TACE alone were collected. The literature was screened according to inclusive criteria, data were extracted and the quality of included studies was assessed, and then meta-analysis was conducted using RevMan 5.1 software. Results A total of 17 RCTs with 907 patients were included. Meta-analysis showed that compared with TACE alone, TACE combined with thermotherapy had a significant difference in 1-year survival rate (HR=2.40, 95%CI 1.65 to 3.48, Plt;0.000 01), 2-year survival rate (HR=3.28, 95%CI 1.87 to 5.76, Plt;0.000 1), total effective rate (RR=1.59, 95%CI 1.42 to 1.79, Plt;0.000 1) and improvement rate of life quality (RR=1.79, 95%CI 1.42 to 2.25, Plt;0.000 1). The incidences of myelosuppression and alimentary canal reactions were lower in TACE combined with thermotherapy group than those in TACE alone group, but statistically significance was only found in myelosuppression (RR=0.79, 95%CI 0.69 to 0.92, P=0.001). Conclusion Compared with TACE alone, TACE combined with thermotherapy can improve long-term survival rate and short-term curative effect, ameliorate the quality of life, and tend to reduce the incidence rate of side effects. But its long-term curative effect and more comprehensive safety still needs to be further verified by more large sample and high quality RCTs.

  • Amplatzer Transcatheter and Surgical Closure for Ostium Secundum Atrial Septal Defects: A Systematic Review

    Objective To determine the efficacy and safety of Amplatzer transcatheter closure and surgical closure for ostium secundum atrial septal defects. Methods MEDLINE (1966-July 2006), EMBASE (1966-July 2006), The Cochrane Library (Issue 2, 2006) and CBMdisc (1979-July 2006) were searched for randomized controlled trials or non-randomized controlled trials. Data were extracted by two reviewers using a specially designed extraction form. The quality of included trials was critically assessed. The Cochrane Collaboration’s RevMan 4.2 software was used for data analysis. Results Sixteen non-RCTs involving 2 043 patients were included. No deaths were reported in 14 trials. The other two trials reported one death respectively in the surgical group. Meta-analysis of 12 trials involving 1 722 patients showed that the procedure success rate for the Amplatzer group was lower than that for the surgical group [WMD:0.95, 95%CI (0.92,0.98)]. Similar results were also found in the complete closure rate in 24-hour follow-up [6 trials involving 1 106 patients, WMD:0.96, 95%CI (0.92 to 1.00)], the complication rate [16 trials involving 1 971 patients, WMD:0.27, 95%CI(0.21 to 0.35)] and the transfusion rate [14 trials involving 1 807 patients, WMD:0.03, 95%CI(0.02 to 0.06)]. Conclusions The success rate for Amplatzer device closure of ASD is lower than that of surgical repair. However, the complication rate, length of hospital stay and transfusion rate are lower or shorter for Amplatzer device closure than for surgical repair. Based on appropriate patient selection, Amplatzer closure of ASD is a safe and effective alternative to surgical repair.

    Objective To evaluate the impact of transcatheter arterial chemoembolization(TACE) on survival and tumor recurrence in patients with primary liver cancer, provide reference of clinical diagnosis and treatment for the primary liver cancer patients. Methods Two hundred and twenty-two cases of primary liver cancer were divided into TACE group (n=110) and control group (n=110), TACE was performed after operation in the TACE group, convention treatment was performed after operation in the control group. The survival and tumor recurrence rates were compared between the TACE group and control group. Results The 1-, 2-, and 3-year survival rates were 83.64%, 56.36%,and 42.73% in the TACE group, respectively, which were 65.45%, 40.91%, and 21.82% in the control group,respectively. The differences were statistically significant (P<0.05). The 1-, 2-, and 3-year tumor recurrence rates were 20.91%, 54.55%, and 67.27% in the TACE group, respectively, which were 38.18%, 57.27%, and 70.91% in the control group, respectively. The 1-year tumor recurrence rate in the TACE group was significantly lower than that in the control group (P<0.05), but the differences of the 2- and 3-year recurrence rates were not statistically significant(P>0.05). Conclusions TACE treatment for primary liver cancer patients can increase long-term survival, but can’tdecrease long-term recurrence.

  • Comparative Analysis Approach for Transcatheter Directed Thrombolysis and Trans-Dorasalis Pedis Vein Thrombolysis in Treatment for Deep Venous Thrombosis of Lower Limbs

    Objective To investigate the feasibility and efficacy of transcatheter directed thrombolysis (TDT) approach in treatment for deep venous thrombosis (DVT) of lower limbs and as compared with trans-dorsal pedis vein thrombolysis (TPVT) approach. Methods The clinical data of 437 patients with acute DVT (184 males and 253 females) at the age of (43±12) years (range 19-76 years) from July 2008 to January 2012 in the First Affiliated Hospital of Zhengzhou University were analyzed retrospectively. Patients in the group TDT received TDT were 293 cases, 32 inferior vena cava filters were implanted. Patients in the group TPVT received TPVT were 65 cases, 4 inferior vena cava filters were implanted. Results The resolution time of thrombus in the group TDT was shorter than that in the group TPVT (6 d versus 9 d, P<0.05). The circumference difference of leg or upper leg before and after treatment in the TDT group was significantly greater than that in the TPVT group (P<0.05). The rate of venous patency was (65.2±15.4)% and preservation rate of valvular function was (78.2±12.6)% in the group TDT, and which was (63.8±16.3)% and (91.1±10.7)% in the group TPVT, respectively. The differences of venous patency rate was not statistically significant(P>0.05) between two groups, but the prevervation rate of valvular function was significant difference (P<0.05) .Hematomas in 3 cases and gross hematuria in 4 cases were observed, and displacement of inferior vena cava filter occurred in 1 patient in the group TDT. The gums bleed or gross hematuria in 5 cases were observed in the group TPVT. Conclusions Both TDT and TPVT can effectively relieve symptoms. TDT can shorten the course of disease, but itincreases functional damage of the deep vein valvular.

  • The Dose of Palliative External-Beam Radiation Do Not Influence The Survival of Patients in Advanced Hepatocellular Carcinoma with Portal Vein Tumor Thrombus

    Objective To evaluate the effectiveness and prognosis of patients in advanced hepatocellular carcinoma (HCC) with portal vein (PV) tumor thrombus received external-beam radiation therapy (EBRT). Methods The clinical data of 126 HCC patients with PV tumor thrombus who were referred for EBRT at our institution from January 2000 to November 2009 were analyzed retrospectively. EBRT was designed to focus on the tumor thrombus with or without primary intrahepatic tumors, to deliver a median total conventional dose of 50 Gy (range of 30-60 Gy). Predictors of survival were identified using univariate and multivariate analysis. Results Unfavorable pretreatment predictors were associated by multivariate analysis with lower albumin and higher α-fetoprotein levels, poorer Child-Pugh liver function classification, poorer intrahepatic tumor control, lymph node metastases, and the two-dimensional EBRT technique. The dose of EBRT showed no significant in both univariate and multivariate survival analysis. Conclusions In patients with HCC, EBRT is effectively prevents progression in cases of PV tumor thrombus, but palliative dose of EBRT is not related to survival.EBRT is not related to survival.

  • Compare The Effects of Two Chemotherapeutic Patterns after Hepatectomy of Hepatocellular Carcinoma with Portal Vein Tumor Thrombus

    Objective To compare the effect of two chemotherapeutic patterns after hepatectomy of hepatocellular carcinoma (HCC) with portal vein tumor thrombi(PVTT). Methods The clinical data of 51 HCC patients with PVTT who were treated in our department from June 2006 to December 2011 were analyzed retrospectively. Fifty-one HCC patients with PVTT who were performed hepatectomy and treatment of antivirus and improve immune were divided into two groups according to chemotherapeutic patterns after operation: portal vein infusion drug deliver system (PVIDDS)group (n=19) and transcatheter arterial chemoembolization(TACE) group(n=32),and to compare the treatment effect of the two groups. Results The recurrence rate of 1-month, 1-year,3-year, and 5-year after operation in TACE group was 3.1%(1/32),46.9%(15/32),84.4%(27/32), and 100%(32/32),respectively. And in PVIDDS group, which was 5.3%(1/19),52.6%(10/19),100%(19/19), and 100%(19/19),respectively. There were no differences in recurrence rate of 1-month, 1-year, and 5-year after operation in two groups(P>0.05). Recurrence rate of 3-year after operation in TACE group was lower than that in PVIDDS group(P<0.05). There were no differences in medial survival time(17.1 months vs.15.9 months), survival rate of 1-year(93.8% vs.94.7%) and 3-year(40.6% vs. 36.8%) after operation in TACE group and PVIDDS group(P>0.05). Survival rate of 5-year after operation in TACE group was higher than that in PVIDDS group(21.9% vs.0, P<0.05). The rate of complication in TACE group was lower than that in PVIDDS group(65.6% vs.94.7%,P<0.05). Conclusions If the HCC patients with PVTT could endure operation,surgical resection should be considered firstly,furthermore antivirus treatment, improving immune,and chemotherapy should be considered after operation. The effect of TACE is better than PVIDDS.
