为了提高支气管动脉灌注化疗（BAI）中晚期肺癌的疗效．本文观察分析了经CT、支气管镜证实的中晚期肺癌120例，均采用seldiner法，经支气管动脉灌注抗癌药物：丝裂霉素、阿霉素、顺铂、卡铂等的治疗效果．结果：中心型肺癌的CR＋PR占83.33％，周围型肺癌的CR＋PR占11.11％，其中多血管型肺癌的CR＋PR占80．26％，少血管型肺癌的CR＋PR占61.90％，三次BAI后改用放疗的病例较继续BAI治疗者平均生存期延长了三个月，得出；中心型肺癌的BAI疗效优于周围型肺癌、多血管型的优于少血管型，三次导管化疗后改用放疗可提高疗效。
In order to improve the efficacy of bronchial arterial infusion chemotherapy (BAI) in advanced lung cancer. This article observed and analyzed 120 patients with advanced and advanced lung cancer confirmed by CT and bronchoscopy. All were treated with seldiner method and transbronchial arterial infusion of anti-cancer drugs: mitomycin, doxorubicin, cisplatin, carboplatin, etc. RESULTS: CR+PR accounted for 83.33% of central type lung cancer, and CR+PR accounted for 11.11% of peripheral type lung cancer. Among them, CR+PR accounted for 80.26% of multi-vessel type lung cancer, and CR+PR accounted for 61.90% of small-vessel type lung cancer. Three times after BAI, radiotherapy was used. The survival time of patients with BAI treatment was prolonged by three months. The clinical efficacy of BAI for central type lung cancer was better than that of peripheral type lung cancer and multiple blood vessels. The use of radiotherapy after three catheters could improve the curative effect. .
