Background: Bronchogenic carcinoma with spread along the mucosal plane presents as an exophytic mass. Most of the submucosal and peribronchial patterns of this malignancy are harder to detect by standard diagnostic procedures such as bronchial washing, brushing and forceps biopsy. We sought to investigate the utility of transbronchial needle aspiration (TBNA) in the diagnosis of bronchogenic carcinoma without intraluminal mass, through prospective analysis of routine diagnostic bronchoscopies performed in a 24-month period, at a tertiary care hospital.Methods: Patients with suspected bronchogenic carcinoma (clinical and radiological) underwent standard computed tomography (CT) of thorax. Further the patients were subjected to conventional TBNA, singly, and in combination with bronchial washings and brushings. The results were analyzed statistically for the diagnostic yield of TBNA.Results: Among the 42 patients assessed, 29 had malignancy confirmed by forceps biopsy or CT guided Fine Needle aspiration cytology or biopsy and bronchoscopy. Among them, 17 cases were detected by a combination of the results of bronchial washing, brushing and TBNA. The individual sensitivities amounted to 3.4% (n=1), 51.72% (n=15) and 27.6% (n=8), respectively. There were no false positive results. Concerning different bronchoscopic sampling techniques, 9 cases were diagnosed solely by bronchial brushings and 2 cases by TBNA alone. No periprocedural complications were encountered.Conclusions: Value of bronchial brushing in the diagnosis of bronchogenic carcinoma without bronchoscopically visible intraluminal mass is above that of conventional TBNA. Addition of bronchial washings, to bronchial brushings and TBNA has an insignificant impact on the diagnosis.

Tissue Diagnosis

<b><i>Background:</i></b> Diagnosis, staging, and molecular profiling of lung cancer are mostly carried out with bronchoscopy or CT-guided aspiration/biopsy. However, patients with locally advanced or advanced disease often harbor “superficial” metastases for which a percutaneous, ultrasound-assisted needle aspiration/biopsy (US-NAB) might represent an equally effective yet less invasive and costly alternative. <b><i>Patients and Methods:</i></b> We reviewed a prospectively collected database of consecutive patients with known/suspected lung cancer who underwent a US-NAB of a suspected “superficial” metastasis. Cancer genotyping was carried out with next-generation sequencing using the Oncomine™ Focus DNA and RNA fusion panels. PD-L1 immunohistochemistry was performed with the SP263 antibody. Feasibility, diagnostic yield for tissue diagnosis, sensitivity for malignancy, diagnostic yield for the molecular profiling, and complications were the study endpoints. <b><i>Results:</i></b> A total of 98 lesions were evaluated, and 93 were biopsied (95% feasibility). The spectrum of sampled sites included lymph nodes (63 patients), bone (11), subcutaneous tissue (8), muscle (7), and the pleura (4). The diagnostic yield for a tissue diagnosis was 93% (91/98). US-NAB correctly identified 85 of the 87 patients finally diagnosed with malignancy (98% sensitivity). Cancer genotyping and PDL1 testing were successfully completed in 41/42 patients (98%) and in 40/50 patients (80%) for whom these tests were requested, respectively. No complications were observed. <b><i>Conclusion:</i></b> US-NAB of “superficial” metastasis of lung cancer is safe and is associated with high success for diagnosis and molecular profiling. In this clinical setting, using US-NAB as a first-step technique would significantly limit the use of more invasive and costly diagnostic procedures.

Abstract Objective Rapid on-site evaluation has long been used for transbronchial needle aspiration or fine-needle aspiration to evaluate the adequacy of biopsy materials for the diagnosis of peripheral lung lesions. However, research on rapid on-site evaluation combined with transbronchial forceps biopsy in the diagnosis of lung carcinoma is rarely reported. Therefore, we aimed to investigate the value of rapid on-site evaluation during transbronchial forceps biopsy for endoscopically visible (tumor, infiltrative and necrotic) or nonvisible (compressive, nonspecific and normal) malignancy. Methods A retrospective analysis was performed between January 2015 and January 2019 in Taihe Hospital with 1216 lung cancer patients who underwent bronchoscopy procedures, and these patients were allocated into the rapid on-site evaluation group and non-rapid on-site evaluation group, depending on the timing of the procedure. According to endoscopic features, bronchoscopic appearance was described as endoscopically visible malignancy (tumor, infiltrative and necrotic) and endoscopically nonvisible malignancy (compressive, nonspecific and normal). The diagnostic yield was compared, and the concordance between the rapid on-site evaluation results and the final histology was analyzed. Results There was a statistically significant difference in the diagnostic yield between the rapid on-site evaluation and non-rapid on-site evaluation groups for endoscopically nonvisible malignancy (74.3% vs. 51.7%, P &lt; 0.05). However, we found no significant improvement in terms of diagnostic yield for endoscopically visible malignancy (95.2% vs. 91.2%, P &gt; 0.05). The rapid on-site evaluation results showed high-level concordance with histology in the diagnosis of squamous cell carcinoma, adenocarcinoma and small cell carcinoma, with kappa values of 0.749 (P &lt; 0.05), 0.728 (P &lt; 0.05) and 0.940 (P &lt; 0.05), respectively. Conclusions The findings demonstrated that the diagnostic yield of transbronchial biopsy for endoscopically nonvisible malignancy (compressive, nonspecific and normal) was significantly improved when rapid on-site evaluation was implemented. In addition, the rapid on-site evaluation results had high-level concordance with the final histological diagnosis.

In this prospective study, we aimed to report our experience with the diagnostic utility of transbronchial needle aspiration (TBNA) in patients with malignant endobronchial lesions detected during routine bronchoscopy. Ninety-four patients were enrolled. TBNA and conventional diagnostic techniques (CDTs: forceps biopsy, brushing, and washing) were performed in all patients. Endobronchial lesions were classified into exophytic mass lesions (EMLs), submucosal disease (SD), and peribronchial disease (PD). The diagnostic yields of TBNA and CDT alone and together were compared according to the lesions’ types, histopathology, and locations. During 3-year period, the addition of TBNA to CDT improved bronchoscopic sensitivity from 70.2% to 94.7% in all lesion types. Addition of TBNA to CDT increased the diagnostic success from 74% to 95% and from 50% to 94% in NSCLC and SCLC, respectively. The diagnostic success was increased in all localizations by the addition of TBNA to CDT, particularly for lesions located at the trachea, main bronchi, and upper lobes. We conclude that the addition of TBNA to CDT increases the diagnostic yield in patients with visible malignant endobronchial lesions, particularly in peribronchial disease, and improves the diagnostic yield of bronchoscopy, in both NSCLC and SCLC and in all bronchoscopic locations, particularly in central and upper lobar lesions.

OBJECTIVE: To evaluate the yield and cost effectiveness of transbronchial needle aspiration (TBNA) in the assessment of mediastinal and/or hilar lymphadenopathy.DESIGN: Retrospective study.SETTING: A university hospital.POPULATION STUDIED: Ninety-six patients referred for bronchoscopy with computed tomographic evidence of significant mediastinal or hilar adenopathy.RESULTS: Ninety-nine patient records were reviewed. Three patients had two separate bronchoscopy procedures. TBNA was positive in 42 patients (44%) and negative in 54 patients. Of the 42 patients with a positive aspirate, 40 had malignant cytology and two had cells consistent with benign disease. The positive TBNA result altered management in 22 of 40 patients with malignant disease and one of two patients with benign disease, thereby avoiding further diagnostic procedures. The cost of these subsequent procedures was estimated at $27,335. No complications related to TBNA were documented.CONCLUSIONS: TBNA is a high-yield, safe and cost effective procedure for the diagnosis and staging of bronchogenic cancer.

Introduction: In recent years, there has been a growing development of molecularly targeted therapies for various types of solid tumors—in particular, in non-small-cell lung cancer (NSCLC). This has required the need for greater quantities of tissue that is able to support ancillary studies, alongside cyto-histological diagnoses for the assessment of molecular targets. Conventional TBNA (cTBNA) and EBUS-guided TBNA (EBUS-TBNA) have shown a high diagnostic yield for malignant mediastinal and/or hilar lymph node enlargement and peribronchial masses; however, few studies have compared these two procedures. We retrospectively compared TBNA patients (EBUS-TBNA and cTBNA) in order to determine the diagnostic yield and material adequacy for subsequent ancillary analyses. Materials and Methods: We retrospectively evaluated 318 patients with clinical suspicion of lung cancer or with disease recurrence. All of the patients underwent TBNA (either EBUS-TBNA or cTBNA) on enlarged mediastinal and/or hilar lymph nodes and peribronchial masses between January 2017 and June 2021 at the University Hospital of Pisa, Italy. After a definitive diagnosis, molecular analyses and an evaluation of PD-L1 expression were performed in the cases of adenocarcinoma, squamous cell carcinoma, and NSCLC, not otherwise specified (NOS). Results: EBUS-TBNA was performed in 199 patients and cTBNA was performed in 119 patients with 374 and 142 lymph nodes, respectively. The overall diagnostic yield for positive diagnoses was 59% (diagnostic rate of 61% in EBUS-TBNA, and 55% in cTBNA). Adenocarcinoma (ADC) was the most frequent diagnosis in both methods. EBUS-TBNA diagnostic adequacy was 72% for molecular analysis, while it was 55.5% for cTBNA, showing a statistical trend (p = 0.08) towards the significance of EBUS. The average percentage of neoplastic cells was also statistically different between the two methods (p = 0.05), reaching 51.19 ± 22.14 in EBUS-TBNA and 45.25 ± 22.84 in cTBNA. With regard to the PD-L1 protein expression, the percentage of positivity was similar in both procedures (86% in EBUS-TBNA, 85% in cTBNA). Conclusions: Conventional TBNA (cTBNA) and EBUS-guided TBNA (EBUS-TBNA) are minimally invasive diagnostic methods that are associated with a high diagnostic yield. However, EBUS-TBNA has an improved diagnostic adequacy for molecular analysis compared to cTBNA, and is associated with a higher average percentage of neoplastic cells.

Initial Sampling

Guidelines have recommended endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and endoscopic ultrasound-guided fine-needle aspiration biopsy as initial sampling approaches of mediastinal lymph nodes for lung cancer staging. However, the small sample volume might restrict the diagnostic utility of needle aspiration in certain mediastinal diseases. We have recently shown that transbronchial mediastinal cryobiopsy, which is capable of providing larger amounts of intact tissue, improves diagnostic yield in rare tumors and benign diseases compared to EBUS-TBNA. Here, we present a case of mediastinal nodular lymphocyte predominant Hodgkin lymphoma successfully diagnosed by endoscopic transesophageal cryobiopsy.

Purpose To evaluate the diagnostic yield and complication rate of 2 different biopsy techniques (fine-needle aspiration, FNA, and core-needle biopsy, CNB) in the diagnosis of pulmonary lesions in 2 distinct periods, 2010-2012 and 2013-2015. Methods We retrospectively analyzed the results of 691 CT-guided lung biopsies in 665 patients who were divided into 2 groups: cohort 1 (January 2010 to December 2012) was composed of 271 consecutive patients with 284 procedures either by FNA or CNB; cohort 2 (January 2013 to December 2015) was composed of 394 patients with 407 CNBs. Univariate and multivariate logistic regression modeling was used for selected outcomes including diagnostic yield, bleeding and pneumothorax. Results Cohort 1 comprised 165 men and 106 women (mean age 68.5 years) with 180 FNAs and 104 CNBs; cohort 2 comprised 229 men and 165 women (mean age 66.4 years) with 407 CNBs. The diagnostic yield increased in cohort 2 with respect to cohort 1. There was a slight increase in CT procedure complications (pneumothorax and bleeding) from cohort 1 to cohort 2. The overall risk of complications was greater for lesions <20 mm and for lesions at >20 mm distance from the pleura. Conclusions CT-guided CNB had a higher diagnostic yield than discretional use of either FNA or CNB; there was a slight but acceptable increase in complication rates.
