Rapid on-site evaluation of endobronchial ultrasound-guided fine-needle aspirates: correlation of adequacy assessment and final diagnosis in patients with bronchogenic carcinoma

Initial and final diagnoses were concordant in 89% of aspirates from patients with carcinoma. All aspirates that were positive at ROSE were concordant. In discordant cases, all aspirates deemed “atypical suspicious for malignancy” and 86% of aspirates deemed “atypical cells” on ROSE had a final diagnosis of carcinoma. The majority of discordant cases with a positive final diagnosis were due to sampling (60%).
