The demographics and prognosis of non-small cell lung cancer patients have changed during the last few decades. We conducted this study to assess the change in demographics and prognosis in resected non-small cell lung cancer patients during a 20-yr single-institution study in Korea. We retrospectively reviewed the medical records of 2,076 non-small cell lung cancer patients who underwent pulmonary resection between 1990 and 2009. Their clinical characteristics and survival were analyzed over a five-year period. With time, the proportions of female, adenocarcinoma, stage IA, and lobectomy patients increased, whereas the proportions of male, squamous cell carcinoma, stage IIIA, and pneumonectomy patients decreased. These demographic changes caused improved prognosis. The five-year survival rate of all patients was 53.9%. The five-year survival rate increased from 31.9% in 1990-1994, to 43.6% in 1995-1999, 51.3% in 2000-2004, and 69.7% in 2005-2009 (P < 0.001). In conclusion, among patients with resected non-small cell lung cancer, the proportions of female, adenocarcinoma, stage IA, and lobectomy patients have increased, and the five-year survival rate has gradually improved during the last 20 yr in Korea.
