Abstract:
Objective To study the clinical values of polyvinyl alcohol chemoembolization and bronchial arterial infusion(BAI) in interventional therapy of central bronchogenic carcinoma.Methods 45 pathologically proved cases of central bronchogenic carcinoma in mid or late period were randomly divided into two groups(control group in 24 cases and experimental group in 21 cases).After detecting the nourishing arteries of bronchogenic carcinoma with angiography,the treating processes were performed.Control group : anticancer drugs were poured into bronchial artery.Experimental group : the feeding arteries of tumors were co-axially superselective catheterized with microcatheters,the anti-neoplasm agents were poured into everyone of feeding arteries according to the blood supply,then the feeding arteries were embolized by polyvinyl alcohol.Results Control group : the obvious effective rate(CR+PR) was 50%.Experimental group:the obvious effective rate was 90.4%.Two cases in control group obtained the chances of radical operation and chemotherapy were performed after operation,the other 22 cases were undergone synthetic treatment.Seven cases in experimental group obtained the chances of radical operation and chemotherapy were performed after operation,14 cases were undergone synthetic treatment.Three cases in control group died and none of in experimental group died in the follow-up of 2~24 months.Conclusion The short-term effect of polyvinyl alcohol embolization is better than those of BAI for interventional therapy of central bronchogenic cancer,but the long-term effect needs a large number of cases to access the real clinical value.
