Background In the era of endobronchial/esophageal ultrasound (EBUS-TBNA/EUS-FNA), many centers forgo conventional transbronchial needle aspiration (C-TBNA) in favour of EBUS-TBNA/EUS-FNA despite no conclusive evidence showing better yields with EBUS-TBNA/EUS-FNA. Objectives Assess the feasibility of an algorithmic approach for mediastinal sampling beginning with C-TBNA utilizing rapid onsite cytologic evaluation. Methods Descriptive analysis of 92 consecutive patients referred for adenopathy that underwent C-TBNA and subsequent EBUS-TBNA/EUS-FNA if C-TBNA was negative or nondiagnostic. Results 92 procedures were analyzed. In 50 (54.3%) of cases, C-TBNA alone was sufficient. EBUS-TBNA was performed after C-TBNA in 27 (29.3%) of cases and EUS-FNA in 33 (35.9%) of cases. The yield was 92.9% for C-TBNA, 92.5% for EBUS-TBNA, and 89.7% for EUS-FNA. There were no statistically significant differences in yields by LN station (P = 0.51), the relationship between yield and LN size (P = 0.37), or time difference in procedures following the algorithm compared to EBUS/EUS only procedures (33.7 minutes versus 32.4 minutes on average [95% CI for difference: −9.1 to 11.7], P = 0.80). Conclusions An algorithmic approach to assess the mediastinum using C-TBNA initially is feasible without sacrificing yield or procedure times. C-TBNA was sufficient for diagnosis in 54.3% of cases and can be efficiently taught in an IP training program.

Objective:To prospectively investigate the value of rapid on-site evaluation (ROSE) in transthoracic fine needle aspiration cytology (FNAC) of patients with pulmonary nodules. Computed tomography (CT)-guided FNA is commonly employed for the diagnosis of lung lesions and the most common reason for not being able to provide a diagnosis in FNA is inadequacy of samples.Materials and Methods:This was a prospective study conducted in the departments of pathology and radiology of our cancer centre. This study had approval from the institutional review board and ethical committee of our institute. Fifty consecutive cases undergoing CT-guided transthoracic FNAC in our centre were included in the study. The smear submitted for ROSE was stained using toluidine blue stain. The specimen adequacy and diagnosis in ROSE was compared with that of the final cytology report, and the concordance regarding adequacy and diagnosis were noted.Results:Smears were adequate in 34 cases (68%) and inadequate in 16 cases (32%) Out of the 16 inadequate cases, 5 (31%) were converted to adequate due to the application of ROSE, thus increasing the adequate number of cases to 39 (78%). A diagnosis of malignancy was made in all 39 adequate cases. Sensitivity of ROSE in determining adequacy was 92% and specificity was 100%. The most common malignancy was adenocarcinoma in 26 cases. Pnemothorax occurred in 2 cases. No significant complications occurred in other cases.Conclusion:CT-guided FNA with ROSE is a safe and useful tool in the diagnostic work-up of lung cancer patients. A multidisciplinary approach along with onsite evaluation of adequacy will increase the diagnostic utility of cytology in lung lesions.

“…More importantly, in an era of targeted therapy, ROSE is performed to ensure collection of adequate and sufficient material for ancillary studies, including immunohistochemistry (IHC) for subtyping of lung cancer and potential molecular testing in these patients. [8][9][10][11][12] PURPOSE OF ROSE 1. To evaluate sampling adequacy of mediastinal LNs as evidenced by the presence of representative normal tissue (lymphoid tissue or anthracotic pigment-laden macrophages) and/or other lesional material (eg, granulomatous inflammation, malignancy).…”

- Rapid on-site evaluation can ensure that the targeted lesion is being sampled and can enable appropriate specimen triage. If available, it should be used with EBUS-TBNA in the diagnosis of lung cancer because it can minimize repeat procedures for additional desired testing (ie, molecular studies). Some studies have shown that ROSE does not adversely affect the number of aspirations, total procedure time of EBUS-TBNA, or the rate of postprocedure complications; it is also helpful in providing a preliminary diagnosis that can reduce the number of additional invasive procedures, such as mediastinoscopy. As EBUS technology continues to evolve, our knowledge of the role of ROSE in EBUS-TBNA for the diagnosis of lung cancer will also continue to grow and evolve.
