Commentary (Hansen)—Limited Small-Cell Lung Cancer: A Potentially Curable Disease

The article by Sherman et al is a broad review of the recent developments in the treatment of patients with small-cell lung cancer who present with limited disease. Intially, the authors emphasize that the increasing use of more intensive and refined staging procedures, such as computed tomography (CT) scan and, more recently, positron-emission tomography (PET) scan, have resulted in stage migration. This phenomenon has led to improved outcomes of both limited and extensive disease, but has not necessarily improved overall survival.
