RESUMO
Objective To evaluate preoperative bronchial atery infusion(PBAI) chemotherapy combined with surgery for patients with stage III A non-small cell lung cancer(NSCLC). Methods Seldinger procedure was used to insert the tube to bronchial artery branch which supplied blood to the tumor. The chemotherapeutic drugs were infused through the tube. After 1～3 courses of PBAI chemotherapy, the patients received operation. The patients receiving surgical treatment without PBAI chemotherapy at the corresponding period were chosen as control group. The radical resection rate and survival rate of the two groups were analyzsed. Results The response rate (CR+PR) of PBAI chemotherapy was 66.8%, and radical resection rate (90.3%) in PBAI chemotherapy group was significantly higher than that in control group(61.1%,P
