During past 3years, we have examined and treated 48 cases of primary lung cancer in
M.C and S.C department, among which male was 41 and female was 7. Most of them
were in 4th and 5th decades. As for type differentiation, epidermoid carcinoma was 23,
anaplastic carcinoma 13, adeno carcinoma 7, and 5 were not specified. Group 1 was
remarkably high in number also in our series but different in sex distribution from other
authors. As it was started in the beginning, it is impossible to make any reliable
statistics with this material because of small number, X-ray patterns were tried to
establish, and 10 categorias were made but it was not to make characteristic pattern to
majority of cases. Operability according to X-ray pattern, duration of symptoms in
connection to different types were observed but no significance was found except few
minor points as was mentioned in each column. Study on the method of diagnosis
revealed that bronchial biopsy was the most reliable method, especially in epidermoid
carcinoma and with quite big number in anaplastic carcinoma. However, in adeno
carcinoma all cases were diagnosed by scalene node biopsy in our series. Only 4 cases
were diagnosed as cancer prior to our O.P.D but others were diagnosed variously,
among which tuberculosis was most predominant. As for the symptome at onset cough
was most prominent in most of cases, and chest pain was the next. In most of the
cases, E.S.R was elevated markedly. Localization did not show any significant result.
Relation between smoking habit and cancer incidence was oserved but no significance
was found in either sex or type of tumor.
