Ganti and colleagues have provided a brief review on the diagnosis of small-cell lung cancer (SCLC) and the roles of chemotherapy and surgery in its management. Notably, in the past three decades, the most significant progress in the treatment of SCLC has mainly involved the use of radiotherapy. Thus, to complement their assessment, we will provide an overview of the role of radiation in the management of limited-stage and extensive-stage SCLC.

Small-cell lung cancer (SCLC) accounts for approximately 15% of the 215,000 new lung cancer diagnoses in the United States annually. With a case-fatality rate greater than 90%, SCLC will be the cause of over 25,000 deaths in 2008 alone.
