Treatment principles in advanced non-small-cell lung cancer.

Non-small-cell lung cancer (NSCLC) accounts for more than three quarters of all lung tumours and is the leading cause of deaths due to cancer in Australia. More than half of the patients with NSCLC present with advanced disease. Radiation therapy has been the mainstay of active treatment for these patients. There is increasing evidence supporting the benefit of chemotherapy as an addition to radiation therapy in locally advanced non-metastatic disease. The use of cisplatin-based chemotherapy prior to radiation therapy would appear to be a new standard of care in patients with stage III B NSCLC. In advanced (metastic) disease, palliation of symptoms remains the major goal of current treatment programmes. This can be achieved with the best supportive care, radiotherapy, and, in selected patients, platinum-based chemotherapy. Clinical trials to test new treatments, with survival, quality of life and cost-benefit as endpoints, are essential. The present study discusses the current status of conventional and newer treatment methods in locally advanced and metastatic disease.
