Neoadjuvant chemotherapy and chemoradiotherapy for non-small cell lung cancer: Current status and future prospects

Of the patients with non-small cell lung cancer, 60% present with localised or locally advanced disease. Although they may be considered potentially curable, the vast majority will die, usually from systemic disease. So far, adjuvant (post-operative) therapy has failed to demonstrate benefit. In contrast, chemotherapy has demonstrated clear advantages when administered prior to, or concurrently with radiotherapy in Stage III disease or prior to surgery in Stage III disease. Chemotherapy administered prior to surgery, termed neoadjuvant therapy, in Stage I and II disease has been demonstrated to be feasible. Several trials employing currently available agents have yielded promising results. Whether these regimens will result in an unequivocal benefit is the subject of several ongoing studies in the US and Europe. Current research is focusing on the role of newer drugs including novel antitubulin agents, growth factor receptor antagonists, eicosanoid modulators and various other agents.
