Abstract
Objective To evaluate the pulmonary metastatic tumor response to different ways of transcatheter arterial infusion.Methods Thirty-five patients with pulmonary metastatic tumors were randomized divided into two groups:15 patients with 49 lesions treated with bronchial arterial infusion(BAI) and 20 patients with 65 lesions treated with bronchial arterial infusion(BAI)combined with pulmonary arterial infusion(PAI).The therapeutic reponse was assessed by the WHO evaluation criteria.Results The total effective rate(CR + PR) of BAI was 65.3%(32/49),PAI + BAI was 61.5%(40/65) showing no statistical difference.The median survival time of BAI was 9 mo,BAI + PAI was 11.5 mo,demonstrating no statistical significance.Conclusions BAI should be the primary treatment for pulmonary metastatic tumor.
