Methods: one hundred and one patients with esophageal carcinoma were divided into two groups. Observing group (49 cases) were treated by whole-course 3DCRT. Patients in control group (52 cases) were treated by conventional radiotherapy. Clinical efficiencies and radiation toxicities were compared between two groups. Results: The side effects including radiation esophagitis (63.2%) and tracheitis (49.0%) decreased in observing group, but there was no significant difference between two groups (69.2% and 55.7% in controls). The 1-, 2-and 3-year tumor local control rates and overall survival rates in the observing group were significantly improved compared with the control group, being respectively 87.8%, 75.5%, 63.3% vs 71.2%, 55.8%, 42.3% and 85.7%, 71.4%, 46.7% vs 69.2%, 51.9%, 26.9% (all P 0.05). Conclusion: The therapeutic effect of whole-course 3DCRT combined with LCAFR for esophageal carcinomas is superior to conventional radiotherapy.展开更多

This study was to evaluate the efficacy and toxicity of LCAHFR combined with FP chemotherapy in treating esophageal cancer. Methods: Reports of randomized clinical trials on LCAHFR combined with FP chemotherapy for esophageal cancer published between January 1999 and January 2009 were researched through Wanfang, CNKI, and PubMed databases. RevMan4.2 software was used for Meta-analysis. Results: Twenty-one reports, including 2030 patients, were included in the meta-analysis. Of the 2030 patients, 1006 underwent LCAHFR (LCAHFR group), and 1024 underwent LCAHFR combined with FP chemotherapy (combination group). Compared with those of the LCAHFR group, the 1-, 2-, 3-, 5-years survival rates and 1-, 2-, 3-year local control rates of the combination group were significant increased, and the acute toxicity was also increased, but chronic toxicity showed no significant difference. C onclusions: LCAHFR combined with FP chemotherapy can improve the survival rate and the local control rate of the patients with esophageal cancer. The increased acute toxicity need to be concerned, whereas the chronic toxicity needs a long-term observation.展开更多
