Evaluation of T1N0M0 lung cancer with CT.

Medical records and radiologic studies of 238 patients with non-small cell lung cancer who had preoperative evaluation by chest radiography and CT were reviewed. Thirty-six patients were staged as T1N0M0 by chest radiograph. Of this group, 18 (50%) had abnormalities on CT requiring additional evaluation. Confirmation of abnormalities was by tissue sampling or clinical follow-up. Evidence for unresectable spread of disease was obtained in 12 (33%). We conclude that routine preoperative staging of T1N0M0 lung cancer with CT has a positive impact on patient management.
