【摘要】 目的 回顾性分析影响中央型肺癌经支气管动脉化疗栓塞的远期疗效相关因素。方法 随访自1994年4月～1999年5月经介入治疗的中央型肺癌187例，回顾性分析影响远期疗效的相关因素。结果 187例中生存3年以上有39例(A组)，3年以下148例(B组)。A、B组中，发现肺癌多血供分别为10例、16例，采用综合治疗(包括静脉化疗，局部放疗和手术切除)分别为35例、38例，介入化疗+栓塞分别为3例、58例，经χ 2 检验P<0.05;A组中Ⅳ期病例1例，介入治疗平均次数4.3次/例;B组中，无Ⅰ、Ⅱ期病例，Ⅲ期82例，Ⅳ期66例，介入治疗平均次数1.8次/例。结论 通过回顾性分析，我们发现肿瘤的分期、供血情况、介入治疗方法等是影响中央型肺癌远期疗效的重要因素;早期诊治、寻找异位供血及综合治疗等是提高远期疗效的关键。
