Role of surgery following induction therapy for stage III non-small cell lung cancer.

Over the last 30 years neoadjuvant treatment of stage IIIA non-small cell lung cancer (NSCLC) followed by surgical resection for stage IIIB disease has significantly improved the overall results of treatment for patients with stage III NSCLC as well as for those with locally invasive tumors. Different chemotherapy regimens have been used, although in most studies some combination of drugs that include cisplatin is the standard. Radiation when given as part of the induction protocol appears to offer a higher rate of resection and complete resection, and higher doses of radiation are associated with better nodal downstaging. Resection in patients with persistent N2 disease and pneumonectomy following induction therapy remain controversial.
