Endoscopic ultrasound (with bronchoscope) fine needle aspiration (EUS-B-FNA) has been recognized as a useful and safe technique in sampling mediastinal lymph nodes. Few data are available on its accuracy in diagnosing pulmonary parenchymal lesions adjacent to the esophagus.We performed an observational, retrospective study aimed to evaluate accuracy and safety of EUS-B-FNA for lung parenchymal abnormalities, in two Italian reference centers. Furthermore, impact of rapid on-site evaluation (ROSE) and lesion anatomical site (i.e. lobe) on diagnostic yield were assessed.From November 2016 to January 2018, 21 patients (52.4% m...

Conclusion: The visual appearance of EBUS-TBNA aspirate may provide a clue to the diagnosis. This may prompt the bronchoscopist to obtain samples for ancillary investigations such as Xpert MTB/RIF in cheesy aspirates and avoid further passes from ‘black’ nodes during lung cancer staging.

CONCLUSIONS:  EBUS-TBNA revealed a specific cause for suspected non-malignant lymphadenopathy in one-third of cases and was associated with excellent specificity. Predominant specific causes were granuloma, besides from tumor. In 3 patients pathogen could be isolated by TBNA. PMID: 29788514 [PubMed - as supplied by publisher]

Conclusions: SSA is highly effective at preserving samples for molecular testing from EBUS-FNA. Therefore a single minimally invasive procedure offers access to novel immunotherapy, enhancing lung cancer care. With increasing emphasis on immunotherapy its value is likely to increase.

Conclusions: Tumor heterogeneity was noticed from spatially distinct regions from advanced primary lung cancers. The single biopsy specimens may not represent the whole landscape of genetic alteration in advanced primary lung cancers.Citation Format: Sang-Won Um, Je-Gun Joung, Su Yeon Lee, Joon Seol Bae, Jinha Park, Woong-Yang Park.
