摘　　要：放疗靶区的界定是影响食管癌精确放射治疗疗效的重要因素。目前食管癌临床靶区（CTV）的勾画范围仍存在较多争议，尚无统一标准。研究提示病理特征、影像学手段及淋巴结转移规律等因素对食管癌CTV勾画可能有指导作用。新的勾画方式如个体化勾画CTV已成为目前的研究热点。Target volume definition is one of the important factors in precise radiotherapy of esophageal carcinoma. However, there is considerable controversy about delineation of esophageal carcinoma clinical target volume （CTV）, and no consistent standard. Recent researches show that pathological characteristics, imaging methods and lymph node metastasis pattern may have guiding functions for CTV delineation. Novel delineation technique such as individual design has been a research hotspot.
