[Availability of diagnosis by percutaneous needle aspiration cytology of the lung in cases who showed a peripheral solitary tumorous shadow on chest Xp and diagnostic rate of transbronchial approach].
We report the availability of diagnosis by percutaneous needle aspiration cytology of the lung (NAC) in 526 cases who showed a peripheral solitary tumorous shadow on chest Xp. The positive rate of the transbronchial approach was 62% (147 of 238) in lung cancer cases and 43% (6 of 14) in metastatic lung tumor cases. The positive rate of NAC in relation to lung cancer increased with decrease of diameter of the tumor. The positive rate of NAC was significantly higher than the positive rate of the transbronchial approach with NAC. Complications of NAC were bloody sputum (11%), pneumothorax (8%) and subcutaneous emphysema (0.2%), which did not create therapeutic problems. Pleural dissemination (0.4%) was a serious complication of NAC.
