Abstract： 目的探讨气管癌、支气管肺癌腔内放射治疗的价值.方法 4例原发气管癌和22例原发支气管肺癌及14例(18处病变)支气管肺癌术后复发者,外放射采用6MV X射线,剂量为DT30～77Gy(平均52Gy);腔内照射采用低剂量率192Ir小线源(1.48BGq),支气管黏膜参考点剂量为4～6Gy/次,总剂量10～53Gy(中位值28Gy).结果 37例肿瘤完全消退(CR),2例部分消退(PR),1例轻微变化(MR),3、5年局部控制率分别为75%和65%.23例生存时间≥3年,3年生存率为57.5%.并发症较少见.结论外放射结合腔内照射治疗对于早期支气管肺癌、局限性气管癌和支气管肺癌术后复发者是有效的治疗手段,长期生存是可能的.
