Perioperative Chemotherapy for NSCLCConclusions • Adjuvant cisplatin chemotherapy improves survival in patients with resected stage II-III NSCLC • Matters of debate • Adjuvant vs. Neoadjuvant ? • Benefit in IB patients ? • Little data for patients > 75 years of age • Which agents work best ? • Molecular markers for selection of therapy ?

Perioperative Chemotherapy for NSCLC • CT screening will increase the incidence of early-stage NSCLC • For stage I-III NSCLC, pre-op staging is fundamental for assignment of neoadjuvant vs. adjuvant chemotherapy • Trials underway which require post-op molecular testing • Molecular markers which are both prognostic of survival, and predictive of benefit from chemotherapy, are still lacking for the majority of patients (smokers!)
