Abstract
INTRODUCTION There has been an increase in endoscopic and bronchoscopic biopsies as minimally invasive methods to obtain specimens from gastrointestinal (GI) or pancreatobiliary lesions and thoracic or mediastinal lesions, respectively. As hospitals undertake more of these procedures, it is important to consider the staffing implications that this has on cytopathology laboratories with respect to support for rapid on-site evaluation (ROSE). MATERIALS AND METHODS Volume and time data from endoscopic ultrasound and bronchoscopic procedures (including endobronchial ultrasound-guided transbronchial needle aspirations and small biopsies with touch preparation) in the GI suite, bronchoscopy suite, or operating room were reviewed for 2 months at 2 different medical centers with ROSE services provided by cytologists or fellows physically present at the procedure and cytopathologists located remotely using telecytology. Statistical analysis was performed to investigate significant trends based on the location of the biopsies and other factors. RESULTS A total of 16 proceduralists performed 159 procedures and submitted 276 different specimens during 16 total weeks at 2 institutions. The total ROSE time for the on-site personnel to cover these procedures was 109.3 hours (bronchoscopy, 62.3 hours [57%]; GI, 29.8 hours [27%]; OR, 17.2 hours [16%]), which represents an average of 0.69 hour (41.4 minutes) per procedure or 0.40 hour (24.0 minutes) per part, with the shortest procedure times per sample recorded during bronchoscopy. When stratified by practice volume for individual proceduralists, the average time per specimen sample submitted was shorter for proceduralists with high volume practices and was most pronounced during bronchoscopy procedures. CONCLUSIONS Endoscopic and bronchoscopic procedures account for an increasing amount of the ROSE time for the cytology team. On average, each ROSE procedure takes 0.69 hour (41.4 minutes) or approximately 0.40 hour (24.0 minutes) per specimen, with shorter time requirements for specimens obtained in bronchoscopy procedures and for operators with high volume practices for endobronchial ultrasound-guided transbronchial needle aspirations. This provides important benchmarking data to calculate staffing needs for cytology to provide ROSE support for different proceduralists.

Abstract
BACKGROUND Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is considered the investigation of choice for sampling mediastinal nodes. A major drawback of EBUS-TBNA is its lower diagnostic yield for lymphoma and benign diseases. EBUS-guided mediastinal cryobiopsy (EBUS-MCB) is a novel technique that provides larger nodal biopsy samples, with an acceptable safety profile. In this study, we aimed to evaluate the diagnostic yield of EBUS-MCB in patients with an inconclusive rapid on-site evaluation (ROSE). METHODS This is a prospective study of patients who underwent EBUS-TBNA for undiagnosed mediastinal lymphadenopathy. Patients in whom ROSE did not yield a diagnosis (nondiagnostic ROSE) or ROSE revealed scanty atypical cells (inadequate ROSE) were subjected to EBUS-MCB. The diagnostic yield, adequacy, and complications of EBUS-MCB were analyzed. RESULTS Of the 196 patients undergoing EBUS-TBNA, 46 patients underwent EBUS-MCB. Thirty-two cases underwent EBUS-MCB for a nondiagnostic ROSE. EBUS-MCB confirmed the diagnosis in 19/32 (59.3%) cases. The additive diagnostic yield of EBUS-MCB over EBUS-TBNA was 43.7% (14/32 cases). In all 14 cases where EBUS-MCB was performed for an inadequate ROSE, the material obtained by EBUS-MCB was adequate for ancillary studies. The most common complication observed was a minor bleed in 13 cases. CONCLUSION EBUS-MCB has a diagnostic yield of 59.3% when performed in cases with a nondiagnostic EBUS-ROSE. The tissue obtained by EBUS-MCB is adequate for ancillary studies. We propose EBUS-MCB as an additional diagnostic step in cases with an inconclusive ROSE while performing EBUS-TBNA. Larger studies are, however, needed before EBUS-MCB can be incorporated in the diagnostic algorithm for the evaluation of mediastinal lesions.

Abstract
Background: No randomized trial has compared the yield of the ProCore needle, a novel needle for endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration (TBNA), with standard needles.Research design and methods: Consecutive subjects with intrathoracic lymphadenopathy due to suspected sarcoidosis were randomized 1:1 to undergo EBUS-TBNA with either the 22-gauge ProCore (EchoTip-ProCore, Cook-Medical) or the 22-gauge standard (Vizishot, Olympus) needle. The primary outcome was the diagnostic sensitivity; the secondary outcomes included the number of adequate aspirates obtained and procedure-related complications.Results: We randomized 100 (mean age, 43.4 years; 53% women) subjects. Of the 84 subjects finally diagnosed with sarcoidosis, the sensitivity of EBUS-TBNA was higher with the ProCore (36/42, 85.7%) versus the standard needle (31/42, 73.8%), although not statistically significant (p = 0.18). We obtained adequate aspirates in 95.2% and 90.5% subjects in the ProCore and the standard needle groups, respectively (p = 0.68). One complication (transient hypoxemia) occurred in each group. There were two incidences of the ProCore needle getting bent during the procedure.Conclusions: We found no difference in the sensitivity, specimen adequacy, or safety of EBUS-TBNA when performed with the ProCore or the Olympus needle in subjects with sarcoidosis. Larger studies are required to confirm our findings.[clinicaltrials.gov: NCT03656003].

Abstract
Abstract
Background
Convex probe endobronchial ultrasound is a minimally invasive technique used for performing real-time transbronchial needle aspiration of enlarged hilar and mediastinal lymph nodes and could be used for diagnosing proximal peribronchial lesions. Although computed tomography, magnetic resonant imaging, and positron emission tomography/computed tomography have relatively high sensitivity for mediastinal evaluation, pathology is the gold standard. This study compared between Echo Tip Ultra HD-EBUS 22G needle and Echo Tip ProCore HD-EBUS 22G needle in diagnosis of mediastinal lesions using convex probe endobronchial ultrasound.
Results
Twenty-four patients with mediastinal lesions were included. Convex probe endobronchial ultrasound-guided transbronchial needle aspiration using both Echo Tip Ultra HD 22G and Echo Tip ProCore HD 22G needles was done to all patients with no peripheral lymph node enlargement. CP-EBUS TBNA had diagnostic accuracy 50%, sensitivity 47.6%, and specificity 100% in diagnosis of mediastinal lesions. The Echo Tip Ultra HD needle had diagnostic accuracy 40.9%, sensitivity 38%, and specificity 100% compared to the Echo Tip ProCore HD needle which had diagnostic accuracy 31.8%, sensitivity 82.5%, and specificity 100%. The difference between both needles was statistically insignificant. The Echo Tip Ultra 22G HD needle had more representative cellularity (82%) compared to the Echo Tip ProCore 22G HD needle (45%) with a significant difference between both needles (p value = 0.001).
Conclusion
Both needles can be used equally in sampling mediastinal lesions. This study supports that Echo Tip Ultra HD and Echo Tip ProCore HD needles can be used equally in sampling of mediastinal lesions and supports ultrasound screening of enlarged supraclavicular and cervical lymph nodes before performing EBUS-TBNA in patients with mediastinal lesions.

Abstract
Intrathoracic lymphadenopathy is a common problem encountered in clinical practice and is caused by a wide variety of diseases. Traditionally, the mediastinal lymph nodes were sampled using conventional transbronchial needle aspiration (TBNA), or surgical methods such as mediastinoscopy, and thoracotomy (open or video-assisted thoracoscopy). However, surgical modalities including mediastinoscopy are invasive, expensive, and not universally available. Moreover, they are associated with considerable morbidity and mortality. Conventional TBNA although minimally invasive has a low diagnostic yield. In the last decade, endobronchial ultrasound-guided TBNA (EBUS-TBNA) has emerged as the diagnostic procedure of choice in evaluating undiagnosed intrathoracic lymphadenopathy. EBUS-TBNA is also currently the preferred modality in the mediastinal staging of lung cancer. The procedure is minimally invasive, safe, and can be performed as a day-care procedure. In the era of personalized medicine in lung cancer, optimizing the procedure, sample collection, and processing are crucial, as more tissue is required for performing a wide array of molecular tests. Despite its widespread use and acceptance, the diagnostic sensitivity of EBUS-TBNA is still low. To maximize the yield, cytologists and physicians should be aware of the technical details of the procedure. Herein, we discuss the technique of performing EBUS-TBNA, its indications, contraindications, and the processing of the samples at our bronchoscopy suite. We also highlight the challenges faced by the cytologists and clinicians while processing EBUS aspirates.

Abstract
The Papanicolaou Society of Cytopathology has developed a set of guidelines for pulmonary cytology including indications for bronchial brushings, washings, and endobronchial ultrasound guided transbronchial fine-needle aspiration (EBUS-TBNA), technical recommendations for cytological sampling, recommended terminology and classification schemes, recommendations for ancillary testing and recommendations for post-cytological management and follow-up. All recommendations are based on the expertise of the authors, an extensive literature review and feedback from presentations at national and international conferences. This document selectively presents the results of these discussions. The present document summarizes recommendations regarding techniques used to obtain cytological and small histologic specimens from the lung and mediastinal lymph nodes including rapid on-site evaluation (ROSE), and the triage of specimens for immunocytochemical and molecular studies.

A retrospective analysis comparing the use of ProCore® with standard fine needle aspiration in endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). Ir J Med Sci 2018; 188:85-88.

Abstract
Endobronchial ultrasound has become first line in the investigation of mediastinal lesions suspicious for malignancy in keeping with National Institute for Health and Care Excellence (NICE) guidelines; however, needle size and type required to maximise diagnostic sensitivity remains unclear. Previous meta-analyses have compared the use of ProCore with standard fine needle aspiration in the assessment of pancreatic masses with differences noted only in the number of passes required. We aim to assess whether a ProCore needle improves diagnostic sensitivity in EBUS-TBNA. Complete follow-up data regarding all 235 patients undergoing EBUS-TBNA in a district general hospital has been collected since the service's inception in 2012. Results were collated and retrospectively analysed allowing for calculation of test sensitivity and specificity. Comparison was then made between procedures where standard fine needle aspiration was performed and those using a ProCore needle. Overall sensitivity of EBUS-TBNA was shown to be 85% with a specificity of 100% in keeping with quoted figures from other centres. Standard fine needle aspiration produced a sensitivity of 77% (85/110) versus ProCore sensitivity of 92% (115/125) with a p value of 0.0016. Thirty percent (33/110) of patients undergoing standard fine needle aspiration required an appropriate crossover technique such as mediastinoscopy or CT-guided FNA in order to either obtain or confirm the diagnosis compared with 15% (19/125) of the ProCore group with a p value of 0.0064. Our retrospective analysis shows a statistically significant difference in the diagnostic sensitivity of sampling mediastinal lymphadenopathy using a ProCore needle compared with standard fine needle aspiration. It also shows that a significantly fewer number of patients required further procedures in order to obtain or confirm the diagnosis. This could potentially be confounded by the retrospective nature of the study design; however, due to the statistical significance demonstrated, further study is required.

Abstract
Context.—
Endobronchial ultrasound–guided transbronchial needle aspiration (EBUS-TBNA) has emerged as a very useful tool in the field of diagnostic respiratory cytology. Rapid on-site evaluation (ROSE) of EBUS-TBNA not only has the potential to improve diagnostic yield of the procedure but also to triage samples for predictive molecular testing to guide personalized treatments for lung cancer.
Objective.—
To provide an overview of the current status of the literature regarding ROSE of EBUS-TBNA in the diagnosis of lung cancer.
Data Sources.—
An electronic literature search in PubMed and Google databases was performed using the following key words: cytology, lung cancer, on-site evaluation, rapid on-site evaluation, and ROSE EBUS-TBNA. Only articles published in English were included in this review.
Conclusions.—
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.
