Abstract
Background Utilisation of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and guide sheath (EBUS-GS) for diagnosis and staging of lung cancer is gaining popularity, however, its impact on clinical practice is unclear. This study aimed to determine the impact of the introduction of endobronchial ultrasound-guided procedures (EBUS) on time to management decision for lung cancer patients, and on the utilisation of other invasive diagnostic modalities, including CT-guided trans-thoracic needle aspiration (CT-TTNA), bronchoscopy, and mediastinoscopy. Methods Hospital records of new primary lung cancer patients presenting in 2007 and 2008 (Pre-EBUS cohort) and in 2010 and 2011 (Post-EBUS cohort) were reviewed retrospectively. Results The Pre-EBUS cohort included 234 patients. Of the 326 patients in the Post-EBUS cohort, 90 had an EBUS procedure (EBUS-TBNA for 19.0 % and EBUS-GS for 10.4 % of cases). The number of CT-TTNAs and bronchoscopies decreased following the introduction of EBUS (p = 0.015 and p < 0.001 respectively). Of 162 CT-TTNAs, 59 (36 %) resulted in complications compared to 1 complication each for bronchoscopy and EBUS-GS, and no complications from EBUS-TBNA. Fewer complications occurred overall in the Post-EBUS cohort compared to the Pre-EBUS cohort (p = 0.0264). The median time to management decision was 17 days (IQR 24) for the Pre-EBUS and 13 days (IQR 21) for the Post-EBUS cohort (p = 0.07). Within the Post-EBUS cohort, median time to management decision was longer for the EBUS group (n = 90) than the Non-EBUS group (17 days (IQR 29) vs. 10 days (IQR 10), p < 0.001). For half of EBUS-TBNA patients (n = 28, 50.0 %) and EBUS-GS patients (n = 14, 50.0 %), EBUS alone provided sufficient diagnostic and/or staging information; these patients had median time to management decision of 10 days. Regression analysis revealed that the number of imaging events, inpatient, and outpatient visits were significant predictors of time to management decision of >28 days; EBUS was not a predictor of time to management decision. Conclusions The introduction of EBUS led to fewer CT-TTNAs and bronchoscopies and did not impact on the time to management decision. EBUS-TBNA or EBUS-GS alone provided sufficient information for diagnosis and/or regional staging in half of the lung cancer patients referred for this investigation.

Abstract
Ultrasound imaging has gained importance in pulmonary medicine over the last decades including conventional transcutaneous ultrasound (TUS), endoscopic ultrasound (EUS), and endobronchial ultrasound (EBUS). Mediastinal lymph node staging affects the management of patients with both operable and inoperable lung cancer (e.g., surgery vs. combined chemoradiation therapy). Tissue sampling is often indicated for accurate nodal staging. Recent international lung cancer staging guidelines clearly state that endosonography (EUS and EBUS) should be the initial tissue sampling test over surgical staging. Mediastinal nodes can be sampled from the airways [EBUS combined with transbronchial needle aspiration (EBUS-TBNA)] or the esophagus [EUS fine needle aspiration (EUS-FNA)]. EBUS and EUS have a complementary diagnostic yield and in combination virtually all mediastinal lymph nodes can be biopsied. Additionally endosonography has an excellent yield in assessing granulomas in patients suspected of sarcoidosis. The aim of this review, in two integrative parts, is to discuss the current role and future perspectives of all ultrasound techniques available for the evaluation of mediastinal lymphadenopathy and mediastinal staging of lung cancer. A specific emphasis will be on learning mediastinal endosonography. Part I is dealing with an introduction into ultrasound techniques, mediastinal lymph node anatomy and diagnostic reach of ultrasound techniques and part II with the clinical work up of neoplastic and inflammatory mediastinal lymphadenopathy using ultrasound techniques and how to learn mediastinal endosonography.

Abstract
BACKGROUND Guidelines recommend mediastinal lymph node sampling as the fi rst invasive diagnostic procedure in patients with suspected lung cancer with mediastinal lymphadenopathy without distant metastases. METHODS Patients were a retrospective cohort of 15,316 patients with lung cancer with regional spread without metastatic disease in the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) or Texas Cancer Registry Medicare-linked databases. Patients were categorized based on the sequencing of invasive diagnostic tests performed: (1) evaluation consistent with guidelines, mediastinal sampling done fi rst; (2) evaluation inconsistent with guidelines, non-small cell lung cancer (NSCLC) present, mediastinal sampling performed but not as part of the fi rst invasive test; (3) evaluation inconsistent with guidelines, NSCLC present, mediastinal sampling never done; and (4) evaluation inconsistent with guidelines, small cell lung cancer. The primary outcome was whether guideline-consistent care was delivered. Secondary outcomes included whether patients with NSCLC ever had mediastinal sampling and use of transbronchial needle aspiration (TBNA) among pulmonologists. RESULTS Only 21% of patients had a diagnostic evaluation consistent with guidelines. Only 56% of patients with NSCLC had mediastinal sampling prior to treatment. There was significant regional variability in guideline-consistent care (range, 12%-29%). Guideline-consistent care was associated with lower patient age, metropolitan areas, and if the physician ordering or performing the test was male, trained in the United States, had seen more patients with lung cancer, and was a pulmonologist or thoracic surgeon who had graduated more recently. More recent pulmonary graduates were also more likely to perform TBNA ( P < .001). CONCLUSIONS Guideline-consistent care varied regionally and was associated with physician-level factors, suggesting that a lack of effective physician training may be contributing to the quality gaps observed.

Abstract
BACKGROUND Guidelines recommend mediastinal lymph node sampling as the first invasive test in patients with suspected lung cancer with mediastinal lymphadenopathy without distant metastases, but there are no comparative effectiveness studies on how test sequencing affects outcomes. The objective was to compare practice patterns and outcomes of diagnostic strategies in patients with lung cancer. METHODS The study included a retrospective cohort of 15,316 patients with lung cancer with regional spread without distant metastases in the Surveillance, Epidemiology, and End Results or Texas Cancer Registry Medicare-linked databases. If the first invasive test involved mediastinal sampling, patients were classified as receiving guideline-consistent care; otherwise, they were classified as receiving guideline-inconsistent care. We used propensity matching to compare the number of tests performed and multivariate logistic regression to compare the frequency of complications. RESULTS Twenty-one percent of patients had guideline-consistent diagnostic evaluations. Among patients with non-small cell lung cancer, 44% never had mediastinal sampling. Patients who had guideline-consistent care required fewer tests than those with guideline-inconsistent care (P < .0001), including thoracotomies (49% vs 80%, P < .001) and CT image-guided biopsies (9% vs 63%, P < .001), although they had more transbronchial needle aspirations (37% vs 4%, P < .001). The consequence was that patients with guideline-consistent care had fewer pneumothoraxes (4.8% vs 25.6%, P < .0001), chest tubes (0.7% vs 4.9%, P < .001), hemorrhages (5.4% vs 10.6%, P < .001), and respiratory failure events (5.3% vs 10.5%, P < .001). CONCLUSIONS Guideline-consistent care with mediastinal sampling first resulted in fewer tests and complications. We found three quality gaps: failure to sample the mediastinum first, failure to sample the mediastinum at all in patients with non-small cell lung cancer, and overuse of thoracotomy.

Abstract
BACKGROUND Evidence-based guidelines recommend mediastinal sampling as the first invasive test in patients with suspected lung cancer and mediastinal adenopathy. The goal of this study was to assess practice patterns and outcomes of diagnostic strategies in this patient population. METHODS We conducted a retrospective analysis of all patients in 2009 who had mediastinal adenopathy without distant metastatic disease to determine whether guideline-consistent care was delivered. Guideline-consistent care was defined as mediastinal lymph node sampling being performed as part of the first invasive procedure. RESULTS One hundred thirty-seven patients were included. Guideline-consistent care was provided in 30 cases (22%). Patients receiving guideline-consistent care had fewer invasive tests than patients with guideline-inconsistent care (1.3 ± 0.5 tests/patient vs 2.3 ± 0.5 tests/patient, respectively; P < .0001) and fewer complications (0 of 30, 0% vs 18 of 108, 17%; P = .01). Most of the complications (16 of 18) were related to CT image-guided needle biopsy. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) was sufficient to guide treatment decisions without any other invasive tests in 88 patients (64%). Although not all the complications and costs due to CT image-guided biopsies could have been avoided, roughly two-thirds could have been eliminated by just changing the testing sequence. CONCLUSION Quality gaps in lung cancer staging in patients with mediastinal adenopathy are common and lead to unnecessary testing and increased complications. In patients with suspected lung cancer without distant metastatic disease with mediastinal adenopathy, EBUS-TBNA should be the first test.

Abstract
OBJECTIVE To evaluate the efficacy of the joint use of cervical mediastinoscopy and video-assisted thoracoscopy for the sampling of mediastinal lymph nodes in patients with non-small cell lung cancer (NSCLC) and candidates for pulmonary resection. METHODS Sixty-two patients diagnosed with NSCLC were submitted to cervical mediastinoscopy and video-assisted thoracoscopy. The samples obtained (from paratracheal chains, anterior and posterior subcarinal chains, paraesophageal chains and pulmonary ligament) were submitted to frozen section analysis. The following variables were also evaluated: age; gender; weight loss; diagnostic method; tomographic findings; histological type; staging; and location and size of the primary tumor. RESULTS In 11 patients, mediastinoscopy showed no involvement of the subcarinal chain, whereas such involvement was identified when video-assisted thoracoscopy was used: positive predictive value = 88.89% (95% CI: 51.75-99.72); negative predictive value = 94.34% (95% CI: 84.34-98.82); prevalence = 17.74% (95% CI: 9.2-29.53); sensitivity = 72.73% (95% CI: 39.03-93.98); and specificity = 98.77% (95% CI: 93.31-99.97). In 60% of the patients with involvement of the posterior subcarinal chain, the primary tumor was in the right inferior lobe. (p = 0.029) CONCLUSIONS The joint use of cervical mediastinoscopy and video-assisted thoracoscopy for the evaluation of posterior mediastinal lymph nodes proved to be an efficacious method. When there is no access to posterior chains by means of ultrasound with transbronchial or transesophageal biopsy, which dispenses with general anesthesia, this should be the method of choice for the correct evaluation of mediastinal lymph nodes in patients with NSCLC.
