title: [Diagnostic invasive procedures in the diagnosis of primary lung cancer. Diagnostic value and complications].
abstract: The invasive procedures used in the diagnosis of primary lung cancer are reviewed based on the literature. The choice of method should be related to its diagnostic accuracy, complications and cost. The chest x-ray provides the background for the further choice of diagnostic method. In central tumors, bronchoscopy meets the requirements and in peripheral lesions percutaneous transthoracic needle biopsy fulfils the conditions. In some centres, mediastinoscopy is preferred in all cases preoperatively, while others only perform this examination if a CT-scan shows mediastinal lymph nodes larger than 1 cm in diameter. If the latter procedure is followed, 10-30% of the patients will have lymph node metastases. Thoracoscopy is used when a pleural effusion remains undiagnosed after pleuracentesis. A considerable amount of patients will be shown to have pleural neoplastic spread even though cytological examination of the pleural fluid did not demonstrate malignant cells. The complication rates in all methods are low.
