This trial will compare the efficacy of docetaxel versus vinorelbine as first-line treatment in elderly patients with advanced NSCLC.

Docetaxel and vinorelbine are well known active agents in the treatment of NSCLC. The standard treatment of elderly patients with advanced NSCLC is monotherapy with a third generation agent. The role of comprehensive geriatric assessment in treatment efficacy and tolerance is an area of investigation.
