title: [The effect of the histoculture drug response assay (HDRA) based perioperative chemotherapy for non-small cell lung cancer].
abstract: In this study we analyze the usefulness of the histoculture drug response assay (HDRA) based perioperative chemotherapy for non-small cell lung cancer. From 2001 to 2006, we examined the chemosensitivity of 70 lung cancer tissues to cisplatin (CDDP), carboplatin (CBDCA), paclitaxel, docetaxel, gemcitabine and irinotecan. In 16 patients with stage III lung cancer who treated induction therapy, the response rate was 100% of 5 patients treated chemotherapy using 2 HDRA-positive drugs, 50% of 8 patient treeated using 1 positive drugs and 0% of 3 patients treated using negative drugs, respectively. The 3-year survival rate of the 5 patients treated using 2 positive drugs was better than that of 11 patient treated using 1 or non positive drugs (p = 0.07). In 39 patients with stage III lung cancer who treated adjuvant chemotherapy, the survival rate of the 14 patients treated chemotherapy using 2 positive drugs was significantly better than that of 25 patients treated using 1 or non positive drugs (p = 0.03). Therefore, HDRA may useful to the improvement of the response to chemotherapy and survival.
