Surgical resection remains the best treatment for Stages I and II non-small cell lung cancer. In Stage IIIA disease the use of induction therapy has become widespread, although evidence supporting this approach is still preliminary. However, in subsets of patients with T3 tumours without mediastinal nodal involvement and those with certain single station, non-bulky N2 disease, surgery alone is still the preferred therapy. Studies show survival rates with surgery alone the same or higher than those achieved by most induction therapy regimens.
