[Histoculture drug response assay (HDRA) guided induction concurrent chemoradiotherapy for mediastinal node-positive non-small cell lung cancer].
To improve the response to chemotherapy for non-small cell lung cancer (NSCLC), effective drugs should be selected for each patient. In 1994 we introduced histoculture drug response assay (HDRA) for NSCLC patients. For clinical N2 patients, biopsy of mediastinal lymph node is performed both for histological diagnosis and for HDRA. Induction concurrent chemoradiotherapy is then performed using HDRA positive chemotherapy agents. We have treated three patients with this strategy. HDRA could be performed using mediastinal lymph node biopsy specimens. Tumor reduction rates of these patients were 80.4%, 85.3%, and 57.1%. Their histological responses were Ef.3, Ef.2, and Ef.1b, respectively. Complete resection was done in all patients. This strategy appeared to be useful in NSCLC patients with mediastinal lymph node metastasis.
