Methods： From January 2004 to October 2006, 70 patients with esophageal carcinoma received late course 3DCRT. Their clinical data were analyzed retrospectively. The short-term clinical results, acute side effects, local control rates and survival rates were evaluated. Results： The complete response rate was 62.9%, partial response rate was 35.7%, and the overall response rate was 98.6%. The 1-, 2-and 3-year local control rates were 77.1%, 51.4% and 45.7%, respectively. The 1-, 2-and 3-year overall survival rates were 75.7%, 54.3% and 38.6%, respectively. The median survival time was 26 months. Conclusion： The technique of late course 3DCRT is an effective treatment for esophageal carcinoma and tend to improve the overall survival rate.展开更多

Modern standard treatments commonly require multidisciplinary approaches, including applications of up-to date medicine and advanced procedures, and necessitate the support of socioeconomic systems. For these reasons, a number of clinical guidelines for HCC from different associations and regions have been presented. External beam radiation therapy was contraindicated for HCC until a few decades ago, but with the development of new technologies, its application has rapidly increased as selective irradiation for tumorous lesions became possible. Most of the guidelines had been opposed or indifferent to radiotherapy in the past, but several guidelines have introduced indications and recommendations for radiotherapy in their updated versions. This review will discuss the characteristics of important guidelines and their contents regarding radiotherapy and will also provide guidance to physicians who are considering applications of locoregional modalities that include radiotherapy.展开更多
