Treatment of stage I lung cancer (T1N0M0, T2N0M0)

Patients with stage I lung cancer can be offered surgical treatment with an excellent prognosis for recovery and long-term cure. The recent revision of the staging definition has rearranged the prognostic categories, further improving the prognosis in Stage I disease by eliminating patients with a higher risk of recurrence. The most vexing issues remaining are the infrequency of diagnosis of lung cancer at this stage and the increasing incidence of lung cancer of all stages, even among nonsmokers. Economical screening, abolition of cigarette smoking, control of airborne environmental carcinogens, and the continued search for effective systemic treatment remain challenges for the future.
