摘要: 在恶性肿瘤颅外转移灶的治疗中体部立体定向放射治疗(SBRT)已得到有效的应用。SBRT具有肿瘤靶区剂量分布集中、靶区周边剂量梯度变化大及靶区周边正常组织受量较小等特点。SBRT放射生物学特点、SBRT治疗机制、SBRT如何整合至全身系统性治疗均得到了进一步的探究。

Abstract: Stereotactic body radiation therapy (SBRT) has been applied in extracranial metastases effectively, with the characteristics of concentrated dose distribution in target region, great dose gradient change in surrounding region and low dose in normal tissue beside target region. The radiation biology characteristics of SBRT, therapeutic mechanism, integration of SBRT into standard systemic therapy regimens have been studied further.
