ABSTRACT
Objective To study the value of CT on defining the gross tumor volume (GTV) in three-dimensional conformal radiotherapy (3DCRT) and intensity-modulated radiation therapy(IMRT), by comparing the GTV contoured on preoperative CT with postoperative pathology guided GTV in patients with non-small cell lung cancer (NSCLC). Methods Thirty-three patients with histologically proved NSCLC had had CT scan of the thorax before sugery. We contoured the GTV for both primary tumor (GTV-T) and the regional metastatic lymph nodes (GTV-N) on preoperative CT scan. The GTV-T was defined on lung window while the GTV-N on mediastinal window. The metastatic lymph node was defined as≥ 10mm in diameter of short axis,while
