Abstract
INTRODUCTION
There is limited data about the diagnostic performance of EBUS-TBNA in patients with mediastinal lymphadenopathy and extrathoracic malignancy.
METHODS
From January 2007 to July 2011, EBUS-TBNA was performed in 68 patients with a history of extrathoracic malignancy (current or past) and suspected mediastinal lymph node metastases.
RESULTS
Thirty-one patients had a final diagnosis of cancer. In nineteen patients, the same histology was identified in the mediastinal nodes as in their prior extrathoracic cancer (colorectal cancer, esophageal cancer and lymphoma). In 12, the diagnosis was not "as expected" (ten lung cancers, one colorectal cancer, one unidentified cancer). Among 37 patients without diagnosis, biopsies in 27 showed normal lymphoid material, two had non-specific inflammation and eight had no contributory results. It was noted that procedures were reported to have been more difficult in these patients.
CONCLUSIONS
Diagnostic performance of EBUS-TBNA in the context of extrathoracic malignancy is very variable depending on the origin of the cancer. Nevertheless, a diagnosis is concluded in almost 50% of the cases. These results underline the necessity to select carefully the indications of EBUS-TBNA in extrathoracic cancer.
