Value of various methods of sampling in the diagnosis of lung cancer

ABSTRACT

The purpose of this study is to compare prospectively the role of transthoracic fine needle aspiration lung biopsy (TFNAB), bronchoscope, sputum cytology in the diagnosis of lung tumors and evaluate the method of small lesion in basing only on chest radiography. We performed 120 TFNAB on 102 in patients with mass lesion visible on chest radiography. The needle of 21 gauge was used. 86 patients with lung cancer, 58 had rigid bronchoscope, 66 had 1 sputum cytological exam, 60 had 2 sputum cytological exams. TFNAB had a highest sensitivity (84.4% for the first time) with a rate of correct cytological typing in 76.7% of cases suffering from lung cancer. It was complicated with pneumothorax in 4 cases (3.3%), hemoptysis in 4 cases with small lesions, two rules in aluminum sawed at interval of 5mm were fixed on the chest wall then the chest radiography was taken to determine the site and the distance of puncture for the TFNAB with good success
