摘要
目的 评价三维适形放射治疗对Ⅲ期非小细胞肺癌患者局部控制率和生存率的影响。方法 2 6例Ⅲ期非小细胞肺癌患者先采用 6 / 15MVX线常规外放疗DT38～ 4 0Gy ,后采用三维适形放疗 2 5～ 3Gy/次 ,1次 /d ,累计量 70～ 74GY。结果 1、2年生存率分别为 6 9 2 %、4 6 1% ,1、2年局部控制率分别为 88 5 %、76 4 %。结论 后程三维适形放射治疗可提高Ⅲ期非小细胞肺癌患者近期生存率及局部控制率 。
Objective To evaluate the effects of late course 3-dimensional conformal radiotherapy(3DCRT)in local control and survival of stage Ⅲ non-small cell lung cancer(NSCLS).Methods The 26 patients with stage Ⅲ NSCLS were given with 6/15MV X-ray total tumor dose was 38～40Gy,and followed by 3DCRT,2.5～3Gy per fraction.1 fraction qd,to a total dose of 70～74Gy.Results The 1-and 2-year survival rates were 69.2%、46.1%.The 1-and 2-year local regional control rates were 88.5%、76.4%.Conclusion Late course 3DCRT can improve the recent survival rate and local control rate in stage Ⅲ NSCLS without severe toxicities
