Study was made on 104 cases (autopsy and biopsy) of primary lung carcinoma of
Koreans obtained during a period of 10 years, 1957 to 1966, at the Department of
Pathology, College of Medicine, Seoul National University.
The frequency ratio or relative incidence of lung cancer among all types of mailgnant
tumors in the same period at this Department was 4.7 per cent in male and female
together, thus ranking the sixth in frequency in male and the sixteenth in female.
The sex ratio oi male and female was 5.5:1. The age distribution of lung cancer
showed the highest frequency in the decade of 50-59 (34%) and also considerably high
frequencies in the decades of 40-49 (27%) and 60-69 (26%). However, when related to
the female only, 60-69 group was in the highest frequency. Ages of 104 cases ranged
from 26 years to 79 years with the average of 48.2 years of age.
The one hundred and four cases of lung carcinoma were classified histologically into
five types : squamous cell carcinoma 45 cases (43%), adenocarcinoma 29 cases (28%),
oat cell carcinoma 17 cases (16%), undifferentiated carcinoma 12 cases (12%) and mixed
type 1 case (0.9%),
It was emphasized that several findings of this study are in concord with the results
of several other countries that are in definitely increasing tendency of lung cancer.
