Lung cancer generally has an unfavorable prognosis. For those with resectable disease, the use of neoadjuvant chemotherapy has the potential to reduce tumor volume, address micrometastatic disease early, and improve outcomes. Randomized trials comparing neoadjuvant platinum-based regimens with surgery alone were able to demonstrate the feasibility and safety of this modality. These trials supported evidence found in phase II trials that utilized third-generation chemotherapies. Still, limitations to these studies exist, such as the inclusion of various disease stages in one study, inter- and intratrial variability of the chemotherapy regimens used, and lack of phase III data comparing neoadjuvant to adjuvant chemotherapy. These heterogeneous factors make it difficult to offer firm recommendations about neoadjuvant chemotherapy. Other matters of contention include the role of postoperative radiation and the concern for increased postoperative complications, especially when a right pneumonectomy is being considered after neoadjuvant chemotherapy. To clarify these issues, well-structured phase III trials comparing adjuvant to neoadjuvant chemotherapy are needed.
