摘要
Objective： The aim of the study was to evaluate the therapeutic effect and safety of whole-course three-dimensional conformal radiotherapy （3DCRT） combined with late-course accelerated hyperfractionated radiotherapy （LCAFR） on patients with esophageal carcinoma. 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.
