[Results of radiotherapy combined with BAI (bronchial artery infusion) for non-small cell lung cancer--analysis of 104 cases].
Results of 104 cases of non-small cell lung cancer (NSCLC) treated by radiotherapy combined with BAI (bronchial artery infusion) were analyzed retrospectively. In 104 cases (84 males and 20 females), 14 cases of stage I, 10 of stage II, 33 of stage IIIA, 29 of stage IIIB and 18 cases of stage IV were included. Overall cumulative survival rate was 11.4% and 50% survival time was 12 months. On PS (performance status), 50% survival time was 1 year and 3 months for both PS 0 and PS 1, 8 months for PS 2 and 2 year for PS 3 (n = 3), respectively. On stage, 50% survival time was 3 year and 4 months for stage I, 1 year and 2 months for stage II, 12 months for stage IIIA, 11 months for stage IIIB and 8 months for stage IV. There was no significant difference of survival rate between squamous cell carcinoma (n = 41) and adenocarcinoma (n = 43). On anticancer agents used for BAI, CDDP group (n = 68) showed better significant 2-year survival rate than that of MMC and/or ADR group (n = 36). Response rate (CR + PR) was 85% (75/88) by radiotherapy with BAI, and 10 cases of CR were obtained. Among 27 cases of 2-year survivors, 21 cases of responders (CR + PR) were included and 4 cases of them showed CR. On these results, radiotherapy combined with BAI seemed to contribute to improve long-term treatment results of NSCLC by higher response rate with the progress of anticancer agent used for BAI.
