Abstract Background: Endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) has been become an important procedure for the diagnosis and staging of lung cancer. Our research identified the effects of different pathological preparation on the diagnosis of lung cancer for specimens obtained by biopsy. Methods: Patients were clinically considered if lung cancer was accompanied by mediastinal or hilar lymph node enlargement between March 2014 and November 2017. Specimens obtained by EBUS-TBNA were treated by three methods: traditional smear cytology, liquid-based cytology (LBC) and histopathology. Results: Of a total of 154 puncture sites from 153 patients, the total positive rate of combination for the three pathological treatment types (histopathology, direct traditional smear, and LBC) was 77.3%. The diagnostic positive rate for histopathology was 68.6%, direct traditional smear was 65.6%, and LBC was 60.4%; there was no significant differences among the three single pathological treatment types (P=0.29), but there was a statistically significant difference between the combination of three treatments and any single pathological treatment type (P=0.01). The diagnostic sensitivities of histopathology combined with traditional smear and histopathology combined LBC were 94.4% and 92.8%, respectively, the specificities and PPVs were both 100%, and the diagnostic accuracies were 95.5% and 94.2%, respectively; the sensitivities, specificities and diagnostic accuracies above were all higher than those of single specimen treatment and lower than those of the three combined. Conclusion: When EBUS-TBNA is used for the diagnosis and staging of lung cancer, the use of histopathological sections combined with direct cytological smear should be sufficient and is the most economical choice.

Objectives: Conventional bronchoscopic techniques and computed tomography-guided transthoracic needle aspiration are widely used in the diagnosis of lung cancer. In some patients diagnosis can be challenging. Endobronchial ultrasound-guided transbronchial needle aspiration can be used in the diagnosis of lung cancer after procedures have failed to provide a diagnosis. We aimed to show the effectiveness of Endobronchial ultrasound-guided transbronchial needle aspiration in the diagnosis of lung cancer in view of the literature and to share the experience from Turkey. Material and Methods: This was a retrospective study conducted between 2014 and 2019. Forty-five patients who were suspected of having lung cancer and underwent Endobronchial ultrasound because diagnosis was not confirmed using methods such as bronchoscopy, computed tomography transthoracic needle aspiration, and peripheral lymph node excision, were included in the study. Results: Three hundred sixty-eight Endobronchial ultrasound procedures were performed. Forty-five patients met the inclusion criteria and were included in the study. Using Endobronchial ultrasound, samples were taken from only mass in eight patients (17.8%), lymph nodes in 30 patients (66.7%), and mass + lymph node in seven (15.5%) patients. Minor complications were seen in five (11.1%) patients and no major complications were seen. Definitive diagnosis was obtained in 35 (77.7%) patients with Endobronchial ultrasound guided transbronchial needle aspiration. Non-small cell lung cancer was identified in 16 patients (45.7%), small cell lung cancer was seen in 15 (42.8%) patients. Seven of ten undiagnosed patients underwent surgical procedures. Conclusion: Endobronchial ultrasound, is an effective and safe method for diagnosing lung cancer after undiagnosed procedures. In selected cases, it can be the first choice for the diagnosis of lung cancer.

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.
