Evolving Chemoradiation Treatment Strategies for Locally Advanced Non-Small-Cell Lung Cancer
December 01, 2003
Survival for patients with stage III nonSMQ-8211-SMQsmall-cell lung cancer hasgradually improved in recent years, with median survival times increasingfrom less than 10 months to more than 18 months. These increasesare thought to result primarily from advances in chemoradiation. Thisarticle reviews major advances in the development of chemoradiationfor patients with locally advanced nonSMQ-8211-SMQsmall-cell lung cancer. Resultsfrom cooperative group trials suggest that concurrent chemoradiationis superior to sequential therapy and may replace sequential therapy asthe new standard of care in patients with good performance status.Technological advances such as 18F-fluorodeoxyglucose positron emissiontomography (PET) staging can be used to improve patient selectionand predict survival. Locoregional control may be improved byaltering radiation fractionation or delivery (eg, hyperfractionation, highdoseinvolved-volume radiotherapy, 3D conformal radiotherapy). Novelagents and regimens in combination with radiation are being investigatedto further improve therapeutic outcomes.
