Induction Chemotherapy for Resectable Non–Small-Cell Lung Cancer
November 01, 2004
Lung cancer remains the leading cause of cancer death in Americanmen and women. Non–small-cell lung cancer (NSCLC) accountsfor 85% of these cases. Although surgery is the best curative approachfor resectable NSCLC, long-term survival for patients with operabledisease remains poor. More than half of patients who initially presentwith stage I to IIIA disease experience relapse of metastatic disease.Postoperative adjuvant therapy has been evaluated in several randomizedtrials, and provides a survival benefit. It appears reasonable tolook to induction chemotherapy, or preoperative chemotherapy, to providea similar improvement in survival with early treatment ofmicrometastatic disease. Multiple trials of induction therapy have beencarried out with encouraging results. The use of various induction regimenswith chemotherapy alone or chemotherapy combined with radiotherapyfor stage IIIA NSCLC is under investigation. Randomized trialsare under way to better define the role of induction therapy in themultimodality treatment of NSCLC.
