目的 研究肺动脉对肺癌供血 ,支气管动脉和肺动脉双重介入治疗 (DAIDoublearterialinfusion)中晚期肺癌的疗效进行分析 ,以进一步提高对中晚期肺癌的疗效。方法 对 2 6例中晚期肺癌行支气管动脉与肺动脉双重插管化疗 ,对造影资料和临床效果进行回顾性综合分析。结果 2 6例共行 32例次双重介入治疗。完全缓解 (CR) 4例 ,部分缓解 (PR) 19例 ,稳定 (S) 2例 ,进展 (P) 1例。总有效率达 96 % ,10例获得Ⅱ期手术切除。结论 双重介入治疗 (DAI)是一种安全有效的治疗中晚期肺癌的方法。研究结果表明 :肺动脉是主要的肺癌供血动脉 ;DAI可使高浓度化疗药物充分与肿瘤细胞接触 ,发挥最佳疗效。同时DAI弥补了单纯BAI治疗的某些不足 ,减少单纯BAI的次数和由BAI引起的并发症。各种组织细胞类型的中晚期肺癌应行双重介入治疗
Objective To study the effect of pulmonary artery on lung cancer, bronchial arterial and pulmonary arteries (DAIDoublearterialinfusion) in the treatment of advanced lung cancer, in order to further improve the efficacy of lung cancer. Methods Twenty-six patients with advanced lung cancer underwent dual-barrel chemotherapy with bronchial artery and pulmonary artery. The angiographic data and clinical effects were retrospectively analyzed. Results Twenty-six patients received 32 cases of double intervention. Complete remission (CR) in 4 patients, partial remission (PR) in 19 patients, stable (S) in 2 patients, and progression (P) in 1 patient. The total effective rate was 96%, and 10 cases received stage II surgical resection. Conclusion Double interventional therapy (DAI) is a safe and effective method for the treatment of advanced lung cancer. The results of the study showed that the pulmonary artery is the main pulmonary arterial feeding artery; DAI can enable high-concentration chemotherapeutic drugs to fully contact with tumor cells and exert the best therapeutic effect. At the same time, DAI makes up for some deficiencies of pure BAI therapy, reducing the number of BAI alone and the complications caused by BAI. The use of dual interventional therapy for advanced and metaphase lung cancer in various histiocytic cell types
