三维适形放射治疗原发性肝癌的现状

Three-dimensional conformal radiation therapy for primary liver tumors

三维适形放射治疗 (3DCRT)是一种新的提高放射治疗增益比的物理措施 ,可在提升肿瘤局部照射剂量的同时 ,降低周围正常组织的受量 ,用于原发性肝癌的治疗 ,可提高肿瘤局控率 ,延长患者生存期 ,减少放射并发症的发生。本文对 3DCRT治疗原发性肝癌的研究进展作一综述。

Three-dimensional conformal radiation therapy(3DCRT) is a new physical method which can enhance the therapeutic gain factor(TGF) of radiotherapy. It can escalate the doses of local tumor and decrease the doses of normal tissue. For patients with primary liver tumors, 3DCRT can increase the local control rates, prolong patients survival and decrease the incidence of radiation-induced complications.
