[Fiberoptic bronchoscopy as diagnostic tool in primitive lung cancer].

OBJECTIVE

The aim of this study was to assess the diagnostic role of fiberoptic bronchoscopy in primitive lung cancers in relation to the sensibility, the specificity and the cost of the examination.

MATERIALS AND

METHODS

We analysed the diagnostic flow-charts of 473 patients with suspected primitive lung cancer consecutively examined during a period of 4 years (2003-2006). The results were analysed comparing patients observed in the period 2003-2004 with those observed during 2005-2006. The number and type of samples collected and the protocols utilized were considered.

RESULTS

In overall patients the reliability of the fiberoptic bronchoscopy was 61.7%, with a significant increase from 47.5% in 2003-2004 to 74.4% in 2005-2006. An important role in improving the diagnostic relevance of the exam was assumed by the more frequent adoption of biopsies and trans-bronchial needle aspiration on parenchyma and mediastinal lymph nodes.

CONCLUSIONS

The fiberoptic-bronchoscopy associated to advanced tissue sampling techniques represents the gold standard for the diagnosis of lung cancer, due to high sensitivity and specificity and moderate cost.
