摘　　要：目的探讨食管癌术后局部和区域复发规律,为食管癌放射治疗(简称放疗)的亚临床区域靶区勾画提供依据。方法回顾性分析该院2009年6月至2011年12月收治的98例食管癌术后复发患者的临床资料。结果 98例患者共发生162个部位复发,其中淋巴结转移占91.8%(90/98),吻合口复发占6.1%(6/98),瘤床复发占2.0%(2/98)。结论不同部位食管癌术后复发部位分布不同,对不同部位食管癌可设计包括不同淋巴结区域的放疗靶区。上纵隔区是各段食管癌术后放疗时靶区勾画的重点。临床分期在Ⅲ期及以上的食管下段癌,锁骨上是重要的预防区域。Objective To discuss the regularity of local and regional postoperative recurrence of esophageal cancer by retrospectively analyzing the recurrence data of esophageal cancer treated with radical operation to provide the evidence for designing the target field of subclinical region in esophageal cancer radiotherapy.Methods To retrospectively analyze the data in 98 patients with postoperative recurrence treated by the thoracoabdominal two-field lymph node dissection without postoperative radiotherapy.Results Among 98 cases,totally 162 sites relapsed,lymph node metastasis accounting for 91.8%（90/98）,anastomotic recurrence accounting for 6.1%（6/98） and tumor bed recurrence accounting for 2.0%（2/98）.Conclusion The distribution of postoperative recurrence sites of different esophageal cancer sites are different.The radiotherapy target areas may be designed for different esophageal cancer sites.The superior mediastinal area is the emphasis of the target region outline after esophageal cancer operation in various sections.In subesophageal cancer with the clinical staging ≥ stage Ⅲ,the supraclavicula is an important preventive area.
