Analysis of our primary bronchogenic carcinoma is restricted to 65 cases that have been regarded as having satisfactory histological and cytological proof of diagnosis by bronchial washing and bronchos opic biopsy and they were primarily diagnosed by roentgenography.
Of these 65 cases, 59 cases were diagnosed by bronchoscopic biopsy and 6 cases were proved by bronchial washing.
In the sex incidence, there were 49 males and 16 females, The peak incidence of bronchogenic carcinoma was 41.5 per cent in the fifth decade, 30.8 per cent in the fourth decade, and 1.5 per cent in the second decade.
Cough, sputum raising, chest pain, and dyspnea were the most common complaints but three patiens had no signs or symptoms.
The pathological classification, metastasis and complication were discussed for these 59 cases.
Radiological classification of lung cancer revealed the following types: central pneumonic form; central solid form; central infiltrating form; peripheral solid form; peripheral cavitary form.
86.2% was central hilar type and 13.8% was peripheral type.
