title: Inoperable localized stage I and stage II non-small-cell lung cancer.
abstract: Early stage, medically inoperable non-small-cell lung cancer is a treatable disease. A thorough clinical work-up is necessary to optimize management for this group of patients. Thoracic radiation therapy has been used for such patients with achievement of durable local control and prolonged survival. To improve upon the results of standard fractionation radiation therapy, novel approaches are needed. Dose escalation may further enhance local tumor control and survival rates. Efforts to minimize irradiation to normal lung parenchyma are necessary. Multiple strategies to optimize the therapeutic ratio are being investigated. Elimination of elective nodal irradiation may reduce late toxicity of treatment but may compromise locoregional control. Other strategies, such as intensity-modulated radiation therapy with dose volume histograms will help minimize lung parenchyma irradiation, which will reduce the probability of radiation pneumonitis. Chemotherapy appears to play a minimal role in the treatment of inoperable limited disease, but researchers continue to conduct investigational trials with active chemotherapeutic agents in the hopes of reducing local and distant tumor failures.
