In 40 we previously knew the original neoplasia. We haven't include those patients with previous EM that finally were diagnosed of lung cancer.Results: The mean age was 64.7 years (36-81), 67% were men. The mean size on CT of the lymph nodes was 1. 29 cm (0.5-3.8). The average of punctures per patient was 6.02 (2-16), obtaining valid samples in 95% of cases. The average of valid sample in these patients was 4.07 (2-10).The final results of EBUS wereView this table:-Two false negative cases were detected. Both of them were finally diagnosed of Lymphoma. In none of the two we previously knew the diagnosis.-33 of the 42 patients had prior PET/CT and all of them showed positive FDG uptake of these lymph nodes with a mean SUVmax of 4.2 (1.7-10.3).-EBUS-TBNA showed a sensibility of 87.5% and a NPV of 86.5 with 12.5% of false negative among patients we could to evaluate.Conclusions:1- EBUS is a useful tool in the diagnosis of mediastinal and hiliar lymph nodes in patients with extrapulmonary malignancy cancer with a sensibility and NPV similar to those found in the staging of lung cancer.2- EBUS is not useful in the diagnose of lymphoma with intrathoracic lymph node affected.
