晚期肺癌在治疗上仍是一个难题。一般采用放疗、化疗、手术或放疗加化疗的综合性治疗,但疗效甚差。由静脉给药,药物首先到达全身,包括骨髓和消化道,毒性反应大,疗效差。由肿瘤营养动脉给药,形成肿瘤局部药物高浓度,增加了肿瘤的药物暴露,故可提高疗效。本文就插管技术,造影表现的疗效进行初步分析。 The treatment of advanced lung cancer is still a problem. General treatment with radiotherapy, chemotherapy, surgery or radiotherapy plus chemotherapy is generally used, but the effect is poor. By intravenous administration, the drug first reaches the whole body, including bone marrow and digestive tract, and has a large toxicity and poor efficacy. The administration of a tumor to a nutrient artery produces a high concentration of local drug in the tumor, which increases the exposure of the tumor to the drug, and thus can improve the therapeutic effect. In this paper, preliminary analysis of the intubation technique and the efficacy of angiographic performance are performed.
