[Current bronchological methods of diagnosis of lung cancer].

On the basis of an analysis of results of studying 541 patients with lung cancer the authors consider that bronchoscopy can diagnose the central lung cancer practically in all the patients including the early stages of the disease before the development of changes in the lungs on roentgenograms. The histological verification of the peripheral lung cancer of the root and median zones is ensured in 77% of patients by bronchofibroscopy under local anesthesia with the transbronchial peripheral forcepts and brush biopsy under the roentgen and TV control. Bronchological diagnosis of cancer of the subpleural zone still remains less effective.
