Abstract:
Plain chest films are the most useful modality in diagnosis of primary lung cancer, but it is difficult tointerpret the radiologic findings by histological types. Authors reviewed chest films of 324 cases ofhistologically confirmed primary lung cancer from Jan. 1974 to April 1982 at Seoul National University. The resulsare as follows; 1. Incidence was most common in the 6th decade as 34.4%. Male to female sex ratio was 3.8:1 andthere was no sex difference in Adenocarcinoma. 2. Distrubution of histologic types of primary lung cancer asfollows; Squamous cell Carcinoma 50.6%, Small Cell Carcinoma 22.5% lange Cell Carcinoma 9.3% Bronchegenic adenocaranoma 10.5% Bronchioloalveolar Cell Carcinoma 1.9%. Adenosquamos Carcinoma 0,6%, Carcinoid Tumor 0.3%, AdenoidCystic Carcinoma 0.3%. 3. Radiologic findings by histologic types as follows; a) Squamous cell carcinoma commonlypresent as collapse(51.8%) peripheral mass (40.8%), pneumonitis(37.2%), hilar involvement(34.8%), and in singleabnormality, peripheral mass (44.4%). b) Small cell carcinoma commonly present as hilar involvement(78.1%),mediastinal wideing or mass (53.4%) and in single abnormality, hilar involvement(58.3%). c) Large cell carciomacommonly present as hilar involvement(50%) pneumonia(46.7%), collapse (40%), peripheral mass(36.7%) and in singleabnormality, large peripheral mass (33.3%). d) Bronchogenic Adenocarcinoma commonly present as peripheralmass(44.1%), collapse (41.2%), pleural effusion (35.2%) and in single abnormality, peripheral mass(50%). e)Solitary peripheral mass commonly present as lobulation(48%) and spiculated margin (51%), but no specific findingsby histologic types. Cavitary formation was most common in Squamous cell carcinoma.
