Abstract

Background/Aims: This study examined the clinical characteristics of patients with lung cancer who were diagnosed at the Gachon University of Medicine and Science Gil Hospital from January 2006 to December 2008.
Methods: The lung cancer data were downloaded from the hospital medical information system using cancer registration information. The patient clinical characteristics were analyzed retrospectively.
Results: A total of 713 patients were diagnosed with lung cancer. Their median age was 69 years, 78.1% were over 60 years old, and 73.1% and 58.2% were men and smokers, respectively. Adenocarcinoma (32.7%) was the most common histologic type, followed by squamous carcinoma (25.9%), unclassifiable non-small-cell lung cancer (NSCLC) (17.3%), and small-cell carcinoma (SCLC) (15.0%). In the NSCLC group, the stage at diagnosis was IA (1.5%), IB (5.6%), IIA (1.3%), IIB (4.3%), IIIA (5.4%), IIIB (23.1%), IV (47.7%), and unknown (11.1%). In the SCLC group, 20.6% of the patients were in the limited stage, 76.6% were in the extensive stage, and 2.8% were unknown. The patients were treated by surgery (9.8%), concurrent chemoradiotherapy (6.7%), radiotherapy only (5.9%), chemotherapy (32.4%), or best supportive care only (29.7%). The median overall survival was 15.3 months (95% CI, 11.5~19.1). The median survival based on histology was adenocarcinoma (35.0 months), squamous (13.5 months), NSCLC (14.2 months), and SCLC (11.8 months) (p=0.0445).
Conclusions: Adenocarcinoma was the most common histologic type at our institute. Most patients were over 60 years of age (78.1%) and had stage III/IV (76.3%) cancer. The survival of patients with adenocarcinoma was longer than that for the other histological types.
