title: Treatment approaches in patients with advanced non-small cell lung cancer and poor performance status.
abstract: It is estimated that 30% to 40% of patients with advanced non-small cell lung cancer (NSCLC) have a poor performance status (PS)-defined as a score of 2 or higher on the Eastern Cooperative Oncology Group scale-because of their disease burden, comorbidities, or both. Survival is shorter in these patients than in those with a better PS, and they do not tolerate chemotherapy as well. There is now evidence that PS2 patients with advanced NSCLC can benefit from single-agent chemotherapy with drugs such as vinorelbine, gemcitabine, paclitaxel, pemetrexed, and docetaxel and that combination chemotherapy may have additional advantages. The optimal treatment for PS2 patients with NSCLC, however, has yet to be determined. The case histories in this article demonstrate that PS2 patients are a heterogeneous group and that selecting the chemotherapy for each patient must take into consideration comorbidities and disease-related symptoms, as well as the potential toxicity of treatment. Large prospective clinical trials are needed to determine whether, and in which patients, combination chemotherapy or novel agents, such as the epidermal growth factor receptor inhibitors or paclitaxel poliglumex, have advantages. Three large phase III trials-Selective Targeting for Efficacy in Lung Cancer, Lower Adverse Reactions trials (STELLAR)-are now being conducted in PS2 patients with NSCLC. It is hoped that their findings will aid in determining the best treatment options for these patients.
