目的：通过肺动脉介入治疗肺癌，寻找一种肺癌介入治疗的新方法。方法：选择TNM分期为以Ⅲb期和Ⅳ期病人20例，分别采用支气管动脉灌注和肺动脉灌注。结果：20例分别接受支气管动脉灌注化疗和肺动脉灌注化疗，CR为0，PR分别为2例和3例，MR分别为5例，SD分别为1例和2例，PD分别为1例和0。用小样本配对比较t检验p＞0．05。结论：两种方法治疗原发性支气管肺癌疗效相仿，肺动脉介入可以作为晚期肺癌和肺癌手术以后巩固治疗的方法。
OBJECTIVE: To explore a new method of interventional therapy for lung cancer by pulmonary artery interventional therapy for lung cancer. Methods: TNM staging was performed in 20 patients with stages Ⅲb and Ⅳ, respectively. Bronchial and pulmonary arterial perfusion were used respectively. Results: Twenty patients received bronchial artery infusion chemotherapy and pulmonary arterial infusion chemotherapy respectively. CR was 0, PR was 2 and 3, MR was 5, SD was 1 and 2, PD was 1 and 0 . Paired with small sample t test p> 0.05. Conclusion: The two methods for the treatment of primary bronchogenic carcinoma have similar curative effect. Pulmonary artery intervention can be used as a method to consolidate the treatment of advanced lung cancer and lung cancer.
