title: Current status of neoadjuvant therapy for non-small cell lung cancer.
abstract: Any program of therapy for clinically advanced non-small cell lung cancer (NSCLC) that would increase the incidence of local tumor control and decrease the likelihood of distant metastatic disease would be of obvious benefit. The objective of neoadjuvant therapy is to eradicate the primary tumor and micrometastatic disease. In the past 10 years, many trials have been completed to evaluate neoadjuvant therapy and they have included sequential chemoradiotherapy, concurrent chemoradiotherapy, chemotherapy/surgery, and chemoradiation/surgery. These trials have predominately been phase 2 trials and have demonstrated that chemotherapy is generally well tolerated, surgery is technically feasible, and operative morbidity and mortality are not excessive. Long-term survival for patients with clinically advanced NSCLC is improved when compared with historic controls. These trials have demonstrated a greater than 50% clinical response rate and in approximately 20% of patients who have undergone resections, the tumor is sterilized. This latter group of patients demonstrate significantly improved survival. Cost-benefit ratios and quality of life have yet to be evaluated. Final determination of the effectiveness of neoadjuvant therapy for NSCLC awaits completion of phase 3 trials.
