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.
【Abstract】ObjectiveTo investigate the proliferation rate of HepG2 cell after multiple thermotherapy and the possible reasons related to it. MethodsAfter HepG2 cell were treaded by ten repeated cycles of heat exposure at 43 ℃ for 80 minutes twice a day, the doubling time of cell was analyzed， and the cell cycle, bcl2 mRNA and bax mRNA were detected. ResultsThe proliferation rate of HepG2 cell which treated with heat speeded up, the percentage of G2 and S in cell cycle increased, the expression of bcl2 mRNA strengthened and the rate of bcl2/bax increased. ConclusionThe speeded proliferation of HepG2 cell after multiple thermotherapy is related to its high percentage of DNA duplicated and dividing cell, strengthened expression of bcl2 mRNA and increased rate of bcl2/bax.
ObjectiveTo systematically review the efficacy and safety of radio-chemotherapy combined with thermotherapy for cervical cancer. MethodsLiterature about the efficacy and safety of radio-chemotherapy combined with thermotherapy for patients with cervical cancer at mid-term/advanced stage was retrieved from digital databases of The Cochrane Library (Issue 7, 2013), PubMed, EMbase, CBM, VIP, CNKI, and WanFang Data, and from their established dates to July, 2013. Data extraction and quality assessment of included studies were conducted by two reviewers independently. RevMan 5.2 software was then used to perform meta-analysis. ResultsA total of 9 randomized controlled trials involving 693 patients were included. The results of meta-analysis showed that, compared with the radio-chemotherapy alone group, the radio-chemotherapy combined with thermotherapy group had significant increased 1-year survival rates (OR=3.05, 95%CI 1.70 to 6.68, P=0.005), 2-year survival rates (OR=2.29, 95%CI 1.19 to 4.38, P=0.01), and overall effective rates (OR=3.66, 95%CI 2.31 to 5.81, P < 0.000 01). The incidence of adverse reactions was no statistically significant between the two groups. ConclusionRadio-chemotherapy combined with thermotherapy improves long-term survival rates and short-term curative effects for patients with cervical cancer at mid-term/advanced stage. However, due to the limited quantity and quality of the included studies, more high quality studies with large sample size and long-term follow-up are still needed to verify the above conclusion.
