Background: In Taiwan, lung cancer is the second most common cause of cancer death and its incidence has been rising for the last 50 years. Shifts in histological types and differences in gender distribution have also accompanied the changed incidence of lung malignancies. Methods: A total of 590 lung cancer patients were interviewed at Kaohsiung Chang-Gung Memorial Hospital, a medical center of Southern Taiwan, in 1997 and 2002. A retrospective investigation confirmed the age-adjusted incident rate in the hospital and demographic variations by different histological types for both genders. The statistical differences were evaluated using the heterogeneity chi-squared test and Cox regression. Results: Results indicated that from 1997 to 2002, the age-adjusted rates of lung cancer decreased by 3.64% at the hospital. The largest percentage of increases in the age-adjusted rate was observed for small cell lung cancer (approximately 8.18%), whereas it decreased by 31.2% for squamous cell carcinoma and increased by 1.62% for adenocarcinoma. Female patients were found to be younger and had longer survival duration. The frequency was the highest for lesions in the upper lobe and patients had more advanced stage in all histological types. The 6-month relative survival rate between the two time-periods did not change appreciably. Conclusions: The age-adjusted incidence rate of adenocarcinoma at the hospital has increased, as well as small cell lung carcinoma. During the study period, early-staging diagnosis and 6-months survival rate did not change appreciably for the different histological lung cancer patients, suggesting that therapeutic and diagnostic advances, prevention or screening procedures had mild effects in southern Taiwan. Further studies are needed for confirmation of our results.
