肿瘤经放射治疗或者多种方法联合治疗后，局部复发经常出现，但局部再程放疗仅适用于少数病人，因其会引起潜在的严重并发症，特别是对大体积的肿瘤进行再程放疗时。采用立体定向放射治疗（SBRT）对复发的椎体转移瘤、头颈部肿瘤、盆腔肿瘤进行再程放疗，不仅能够提高局部控制率并减轻症状，同时还能够减少正常组织不良反应。 SBRT在临床上是一种安全有效的方法，建议将SBRT作为控制局部症状的重要治疗手段。

After radiation therapy or combination therapy, local tumor recurrence appears frequently.However, only few patients are suitable for partial re-radiotheraphy, becasue it may cause potentially serious complications, especially in large volume tumor re-radiotheraphy. With stereotactic body radiation therapy(SBRT), we can improve local control rate, relieve symptoms and reduce normal tissues adverse reaction for recurrence of vertebral metastases, head and neck tumors, and pelvic tumors. SBRT is a safe and effective treatment, and is recommended as an important control local symptoms treatment.
