食管癌恶性程度高,全球范围内食管癌死亡率居恶性肿瘤的第6位。大多数食管癌的治疗首选手术切除,但根治术后复发率仍较高,局部复发是治疗失败的主要原因,术后预防性放射治疗可提高局部控制率。然而,放射治疗靶区的范围仍存在争议,尤其是胸下段食管癌术后患者行放射治疗时是否需包含锁骨上区淋巴结照射。部分学者认为增加双侧锁骨上区淋巴结照射无意义,但有更多的研究显示增加锁骨上区淋巴结照射可以减少锁骨上区复发率,术后放射治疗时需重点考虑。
Esophageal cancer has a high degree of malignancy and the sixth leading cause of death from esophageal cancer worldwide. Most esophageal cancer treatment is the preferred surgical resection, but the recurrence rate after radical operation is still high. Local recurrence is the main reason for the failure of treatment. Postoperative prophylactic radiation therapy can improve the local control rate. However, the scope of the radiotherapy target is still controversial, especially if the patients undergoing thoracic esophageal cancer need radiotherapy to include supraclavicular lymph node irradiation. Some scholars believe that the increase of bilateral supraclavicular lymph node irradiation is meaningless, but more studies have shown that increased supraclavicular lymph node irradiation can reduce the recurrence rate of the supraclavicular area, postoperative radiotherapy should be the key consideration.
