The Analysis of Cell Type and Age Patern in Lung Cancer Patients within Six Years

Study objectives: Some epidemiological characters are said to be changed occasionally in lung cancer (LC). Design and Setting This study was designed to evaluate the clinical files of last six years ret­rospectively to answer if age patern and histological cell type of LC patients change within years or not.

Patients or Materials: The cell type, age patern and year of dagnosis were obtained in all LC pa­tients. Measurements and

Results: Of totally 2083 patients with LC, 2029 (97.4%) were men and 54 (2.6%) were women. The mean age was 61.3 years. In histopatologically classified group (n:1870), non­small cell LC and small cell LC were reported in 1515 (81%) and 355 (19%). There was no tendency of change for histological cell types in LC within six years (p>0.05). The mean ages of LC patients during diagnosis did not change in both gender within six years (p>0.05). By classifying the patients with LC according to the ages, it was seen that there was no significant change in the number of cases below 40 years old, 41-60 years and over 60 years old, in six years (p>0.05)

Conclusions: There is no tendency of change for frequencies of histo­logical cell types in LC, within last six years. The mean ages of LC pa­tients during diagnosis did not change in both gender and the number of cases below 40 years old or above 60 years old did not increase.
