Objective To compare the clinical efficacy and the adverse reaction of transcatheter arteri-al chemoembolization( TACE)alone and combined with stereotactic body radiation therapy( SBRT)in patients with primary hepatic carcinoma by a Meta-analysis. Methods PubMed,Cochrane Library,EMBase,Ovid, MEDLIN,CNKI,CBMdisc,VIP and Wanfang were searched to identify the controlled clinical trials of TACE and SBRT for primary hepatic carcinoma. The obtained data were analyzed using Review Manager version 5. 2 provided by Cochrane Collaboration. To analysis the short-term effect of TACE alone or combined with SBRT, the rate of local tumor control and the difference of one,two,three and five-year survival rate. Results A total of 1 143 patients from 10 controlled clinical trials were involved according to the inclusion criteria. The Meta-analysis showed that TACE and SBRT group significantly increased the short-term effective rate,the rate of local tumor control,l-,2-,3-and 5-year overall survival rates(RR=1. 43,95%CI:1. 32-1. 56,P﹤0. 000 01;RR=2. 09,95%CI:1. 63-2. 69,P﹤0. 000 01;RR=1. 31,95%CI:1. 21-1. 42,P﹤0. 000 01;RR=1. 46, 95%CI:1. 23-1. 72,P﹤0. 000 01;RR=1. 76,95%CI:1. 14-2. 71,P=0. 01;RR=2. 29,95%CI:1. 22-4. 32, P=0. 01). There was no statistically significant difference between the two groups on adverse events such as leucopenia(RR=0.97,P =0. 61),thrombocytopenia(RR =0. 99,P =0.85),hemoglobin decrease(RR =0. 95,P=0. 63),nausea and vomiting(RR=1. 00,P=0. 98),liver function damage(RR=0. 98,P=0. 87). Conclusion Compared with TACE,TACE combined with SBRT can increase the short-term effective rate,the rate of local tumor control,the 1-,2-,3-and 5-year overall survival time of the patients,and does not increase the incidence of adverse reaction. However high-quality trials with large sample sizes are still needed to verify the long-term efficacy and safety.

Objective To analyze the long?term efficacy of intensity?modulated radiotherapy (IMRT) with or without chemotherapy in treatment of 454 patients with nasopharyngeal carcinoma (NPC) and its influencing factors. Methods A retrospective analysis was performed on the clinical data of 454 patients with non?metastatic NPC who received IMRT with or without chemotherapy in our center from 2007 to 2012. Prescribed doses of 69. 96?73. 92 Gy in 33 fractions, 69. 96 Gy in 33 fractions, 60. 06 Gy in 33 fractions, and 50. 96 Gy in 28 fractions were applied to nasopharyngeal gross tumor volume, cervical metastatic lymph nodes, high?risk drainage area, and low?risk drainage area, respectively. In all patients, 438 received induction chemotherapy, 420 concurrent chemotherapy, and 216 adjuvant chemotherapy, most of which were based on cisplatin and taxol. The Kaplan?Meier method was used for calculating survival rates and the log?rank test was used for survival difference analysis and univariate prognostic analysis. The Cox model was used for the multivariate prognostic analysis. Results The 3?year sample size was 210. The 3?year overall survival ( OS ) , local recurrence?free survival, nodal relapse?free survival, progression?free survival, and distant metastasis?free survival ( DMFS) rates were 88. 1%, 91. 0%, 90. 7%, 80. 5%, and 85. 1%, respectively. Age, T stage, and N stage were influencing factors for the OS rate ( P=0. 011;P=0. 005;P=0. 033);T stage and N stage were influencing factors for the disease progression?free survival ( P=0. 017;P=0. 005) and DMFS ( P=0. 012;P=0. 019) . The grade≥3 acute and late adverse reactions included hematological toxicity , oral mucositis , xerostomia , dysphagia , and brain injury . Conclusions IMRT promotes the long?term survival rates in patients with NPC. The distant metastasis is the major reason for treatment failure. The adverse reactions induced by IMRT combined with chemotherapy are tolerable.

Objective:To investigate the outcomes of the regimen with docetaxel, cisplatin, and 5-fluorouracil (TPF regimen) in chrono-chemotherapy, and evaluate the feasibility of reducing the toxicity and immunological damage in nasopharyngeal carcinoma (NPC) patients with distant metastasis at preliminary diagnosis, then to compare the advantages and disadvantages between chrono-che-motherapy and traditional chemotherapy. Methods:A total of 46 NPC patients with distant metastasis at preliminary diagnosis (UICC 2010 stage IVc) were enrolled in this study. These NPC patients were randomly divided into chrono-chemotherapy and conventional chemotherapy groups, with 23 cases for each group. TPF neo-adjuvant chemotherapy was conducted in both groups for two cycles, with 21 days to 28 days for each cycle. The following regimen was used for the chrono-chemotherapy group:docetaxel 75 mg/m2, infu-sion, d1;cisplatin 75 mg/m2, 10:00 a.m.-10:00 p.m., continuous infusion, d1-d5;and fluorouracil 750 mg/(m2 · d), 10:00 p.m.-10:00 a. m., continuous intravenous infusion, d1-d5. The following regimen was used for the conventional chemotherapy group:docetaxel 75 mg/m2, infusion, d1;cisplatin 75 mg/m2, infusion, d1;and fluorouracil 750 mg/(m2· d), continuous infusion, d1-d5, 120 h. Patients who obtained therapeutic efficacy via induction chemotherapy were provided with intensity-modulated radiotherapy as a concurrent radio-therapy and chemotherapy (DDP 100 mg/m2, infusion, d1-d2, with 21 days each cycle and a total of two courses). One month after con-current chemoradiation, an adjuvant chemotherapy with the same regimen as the induction chemotherapy was employed for a total of two courses. Acute and late toxicities were graded in accordance with the Common Terminology Criteria for Adverse Events v3.0 scor-ing. Tumor response was evaluated using the 2000 Response Evaluation Criteria in Solid Tumors. The effective rates included complete and partial responses. Relevant data were analyzed by SPSS16.0 statistical software. Results:More emesis was observed at Grade 2 or above in the conventional chemotherapy group than in the chrono-chemotherapy group, with statistical significance between the two groups (P=0.035). After chemotherapy, the value of CD4/CD8 increased in the chrono-chemotherapy group and decreased in the con-ventional chemotherapy group, with statistical significance between the two groups (P=0.033). Conclusion:The proposed chrono-che-motherapy outperforms conventional chemotherapy in reducing the occurrence of severe vomiting. This chrono-chemotherapy may be advantageous in reducing severe bone marrow depression and may play a positive role in the immune function of NPC patients.
