RESUMEN

BACKGROUND AND OBJECTIVE: Little is known about malignant central airway obstruction (MCAO) complicating the metastatic spread of non-bronchogenic solid cancers (NBC) and their bronchoscopic management. This study aimed to describe the epidemiology of this population and determine prognostic factors before therapeutic bronchoscopy (TB). METHODS: In this multicenter study using the EpiGETIF registry, we analysed patients treated with TB for MCAO caused by NBC between January 2019 and December 2022. RESULTS: From a database of 2389 patients, 436 patients (18%) with MCAO and NBC were identified. After excluding patients with direct local invasion, 214 patients (8.9%) were analysed. The main primaries involved were kidney (17.8%), colon (16.4%), sarcoma (15.4%), thyroid (8.9%) and head and neck (7.9%) cancers. Most patients (63.8%) had already received one or more lines of systemic treatment. Obstructions were purely intrinsic in 58.2%, extrinsic in 11.1% and mixed in 30.8%. Mechanical debulking was used in 73.4% of cases, combined with thermal techniques in 25.6% of cases. Airway stenting was required in 38.4% of patients. Median survival after TB was 11.2 months, influenced by histology (p = 0.002), performance status (p = 0.019), initial hypoxia (HR 1.45 [1.01-2.18]), prior oncologic treatment received (HR 1.82 [1.28-2.56], p < 0.001) and assessment of success at the end of the procedure (HR 0.66 [0.44-0.99], p < 0.001). Complications rate was 8.8%, mostly mild, with no procedure-related mortality. CONCLUSION: TB for MCAO caused by a NBC metastasis provides rapid improvement of symptoms and prolonged survival. Patients should be promptly referred by medical oncologists for bronchoscopic management based on the prognostic factors identified.

RESUMEN

BACKGROUND AND OBJECTIVE: EpiGETIF is a web-based, multicentre clinical database created in 2019 aiming for prospective collection of data regarding therapeutic rigid bronchoscopy (TB) for malignant central airway obstruction (MCAO). METHODS: Patients were enrolled into the registry from January 2019 to November 2022. Data were prospectively entered through a web-interface, using standardized definitions for each item. The objective of this first extraction of data was to describe the population and the techniques used among the included centres to target, facilitate and encourage further studies in TB. RESULTS: Overall, 2118 patients from 36 centres were included. Patients were on average 63.7 years old, mostly male and smokers. Most patients had a WHO score ≤2 (70.2%) and 39.6% required preoperative oxygen support, including mechanical ventilation in 6.7%. 62.4% had an already known histologic diagnosis but only 46.3% had received any oncologic treatment. Most tumours were bronchogenic (60.6%), causing mainly intrinsic or mixed obstruction (43.3% and 41.5%, respectively). Mechanical debulking was the most frequent technique (67.3%), while laser (9.8%) and cryo-recanalization (2.7%) use depended on local expertise. Stenting was required in 54.7%, silicone being the main type of stent used (55.3%). 96.3% of procedure results were considered at least partially successful, resulting in a mean 4.1 points decrease on the Borg scale of dyspnoea. Complications were noted in 10.9%. CONCLUSION: This study exposes a high volume of TB that could represent a good source of future studies given the dismal amount of data about the effects of TB in certain populations and situations.

RESUMEN

BACKGROUND: 3-9% of low-grade preinvasive bronchial lesions progress to cancer. This study assessed the usefulness of an intensive bronchoscopy surveillance strategy in patients with bronchial lesions up to moderate squamous dysplasia. METHODS: SELEPREBB (ClinicalTrials.gov NCT00213603) was a randomised study conducted in 17 French centres. After baseline lung computed tomography (CT) and autofluorescence bronchoscopy (AFB) to exclude lung cancer and bronchial severe squamous dysplasia or carcinoma in situ (CIS), patients were assigned to standard surveillance (arm A) with CT and AFB at 36 months or to intensive surveillance (arm B) with AFB every 6 months. Further long-term data were obtained with a median follow-up of 4.7 years. RESULTS: 364 patients were randomised (A: 180, B: 184). 27 patients developed invasive lung cancer and two developed persistent CIS during the study, with no difference between arms (OR 0.63, 95% CI 0.20-1.96, p=0.42). Mild or moderate dysplasia at baseline bronchoscopy was a significant lung cancer risk factor both at 3 years (8 of 74 patients, OR 6.9, 95% CI 2.5-18.9, p<0.001) and at maximum follow-up (16 of 74 patients, OR 5.9, 95% CI 2.9-12.0, p<0.001). Smoking cessation was significantly associated with clearance of bronchial dysplasia on follow-up (OR 0.12, 95% CI 0.01-0.66, p=0.005) and with a reduced risk of lung cancer at 5 years (OR 0.15, 95% CI 0.003-0.99, p=0.04). CONCLUSION: Patients with mild or moderate dysplasia are at very high risk for lung cancer at 5 years, with smoking cessation significantly reducing the risk. Whereas intensive bronchoscopy surveillance does not improve patient outcomes, the identification of bronchial dysplasia using initial bronchoscopy maybe useful for risk stratification strategies in lung cancer screening programmes.

RESUMEN

BACKGROUND: Tracheobronchopathia osteochondroplastica (TO) is a rare condition of unknown etiology. TO is characterized by submucosal nodules, with or without calcifications, protruding in the anterolateral walls of the trachea and proximal bronchi. The objective of this study was to describe TO features and associated comorbidities in a series of patients. METHODS: Patients suffering from TO were retrospectively included by investigators from the Groupe d'Endoscopie Thoracique et Interventionnelle Francophone (GETIF). Demographic, clinical, comorbidities, bronchoscopic, functional, and radiological characteristics, and outcomes were recorded and analyzed. RESULTS: Thirty-six patients were included (69% male with a mean of 65 ± 12 years). Chronic symptoms were described by 81% of patients including cough (74%) and dyspnea on exertion (74%). TO was associated with COPD in 19% of the cases and gastroesophageal reflux disease in 6%. A mild to severe airflow obstruction was present in 55% of the cases. CT scan showed tracheal submucosal nodules in 93% of patients and tracheal stenosis in 17%. Bronchoscopy identified TO lesions in the trachea in 65% of the cases, and 66% of them were scattered. A bronchoscopic reevaluation was performed in 7 cases, 9 ± 14 months [1-56] after initial diagnosis, and showed the stability of lesions in all cases. Three patients underwent interventional bronchoscopic treatment. CONCLUSION: The diagnosis of TO relies on typical bronchoscopic findings and can be evoked on a CT scan. Histologic diagnosis can be useful in atypical cases for differential diagnosis. Given its low consequences in terms of symptoms, lung functions, and evolution, no treatment is usually required.

RESUMEN

BACKGROUND: Therapeutic bronchoscopy (TB) is an accepted strategy for the symptomatic management of central airway malignant obstruction. Stent insertion is recommended in case of extrinsic compression, but its value in preventing airway re-obstruction after endobronchial treatment without extrinsic compression is unknown. OBJECTIVE: Silicone stent Placement in symptomatic airway Obstruction due to non-small cell lung Cancer (SPOC) is the first randomized controlled trial investigating the potential benefit of silicone stent insertion after successful TB in symptomatic malignant airway obstruction without extrinsic compression. METHOD: We planned an inclusion of 170 patients in each group (stent or no stent) over a period of 3 years with 1-year follow-up. The 1-year survival rate without symptomatic local recurrence was the main endpoint. Recurrence rate, survival, quality of life, and stent tolerance were secondary endpoints. During 1-year follow-up, clinical events were monitored by flexible bronchoscopies and were evaluated by an independent expert committee. RESULTS: Seventy-eight patients (mean age 65 years) were randomized into 2 arms: stents (n = 40) or no stents (n = 38) after IB. Consequently, our main endpoint could not be statistically answered. Improvement of dyspnea symptoms is noticeable in each group but lasts longer in the stent group. Stents do not change the survival curve but reduce unattended bronchoscopies. In the no stent group, 19 new TB were performed with 16 stents inserted contrasting with 10 rigid bronchoscopies and 3 stents placed in the stent group. In a subgroup analysis according to the oncologic management protocol following TB (first-line treatment and other lines or palliation), the beneficial effect of stenting on obstruction recurrence was highly significant (p < 0.002), but was not observed in the naïve group, free from first-line chemotherapy. CONCLUSION: Silicone stent placement maintains the benefit of TB after 1 year on dyspnea score, obstruction's recurrence, and the need for new TB. Stenting does not affect the quality of life and is suggested for patients after failure of first-line chemotherapy. It is not suggested in patients without previous oncologic treatment.

RESUMEN

BACKGROUND: Minimally invasive surgery of pulmonary nodules allows suboptimal palpation of the lung compared to open thoracotomy. OBJECTIVE: The objective of this study was to assess endoscopic pleural dye marking using radial endobronchial ultrasound (r-EBUS) and virtual bronchoscopy to localize small peripheral lung nodules immediately before minimally invasive resection. METHODS: The endoscopic procedure was performed without fluoroscopy, under general anesthesia in the operating room immediately before minimally invasive surgery. Then, 1 mL of methylene blue (0.5%) was instilled into the guide sheath, wedged in the subpleural space. Wedge resection or segmentectomy were guided by visualization of the dye on the pleural surface. Contribution of dye marking to the surgical procedure was rated by the surgeon. RESULTS: Twenty-five nodules, including 6 ground glass opacities, were resected in 22 patients by video-assisted thoracoscopic wedge resection (n = 11) or robotic-assisted thoracoscopic surgery (10 segmentectomies and 1 wedge resection). The median greatest diameter of nodules was 8 mm. No conversion to open thoracotomy was needed. The endoscopic procedure added an average 10 min to surgical resection. The dye was visible on the pleural surface in 24 cases. Histological diagnosis and free margin resection were obtained in all cases. Median skin-to-skin operating time was 90 min for robotic segmentectomy and 40 min for video-assisted wedge resection. The same operative precision was considered impossible by the surgeon without dye marking in 21 cases. CONCLUSIONS: Dye marking using r-EBUS and virtual bronchoscopy can be easily and safely performed to localize small pulmonary nodules immediately before minimally invasive resection.

RESUMEN

BACKGROUND AND OBJECTIVE: Treatment optimization of non-squamous non-small-cell lung cancers (nonSq-NSCLC) relies on the molecular analysis of the tumour. We aimed to assess the predictive factors of molecular analysis feasibility (MAF) from samples of peripheral nonSq-NSCLC obtained by radial endobronchial ultrasound bronchoscopy (r-EBUS) and 1.5 mm microbiopsy forceps. METHODS: We reviewed data from consecutive peripheral lung nodules sampled with r-EBUS between January 2012 and July 2014 at a single French University Hospital. nonSq-NSCLC were systematically analysed for EGFR, KRAS, ALK, HER2, PI3K and BRAF throughout the study, and c-MET and ROS1 alterations for the last 10 months. RESULTS: Of 111 nonSq-NSCLC diagnosed by r-EBUS (113 procedures, mean nodule diameter 28 ± 15 mm), 88 were analysed for EGFR and ALK, 87 for KRAS, 86 for HER2, PI3K and BRAF and 14 for c-MET. Forty-one mutations were identified (23 KRAS, 10 EGFR, 2 BRAF, 1 HER2 and 5 ALK rearrangements). Four c-MET overexpressions were noted. MAF rose from 67% for the first 57 procedures to 89% for the last 56 procedures (P = 0.02) likely due to a higher number of biopsies performed (2 ± 1 vs 3 ± 2, P = 0.005). Upper or middle lobe location (OR 1.19, 95% CI: 1.02-1.38, P = 0.03), and at least three biopsies (OR 1.20, 95% CI: 1.04-1.40, P = 0.02) were predictive factors of MAF. Percentage of tumour cells, size of lesion and distance to the pleura did not correlate with MAF. CONCLUSION: Multi-gene molecular analysis could be performed in nearly 80% of paraffin-embedded biopsies or smear specimens sampled by r-EBUS assisted bronchoscopy of peripheral tumoral lung nodules.

RESUMEN

Background: Ultrasonography is widely used in critical care practice. The status of related studies remains unclear. The purpose of this study is to analyze current literature investigating the use of ultrasound in critical care units by using bibliometric analysis. Methods: The Science Citation Index Expanded (SCI-E) database was used for data retrieval. The search formula for literature retrieval was "ultrasound" OR "ultrasonography" AND "intensive care unit" OR "critical care unit" OR "intensive care" OR "critical care". The bibliometric software package of R software was used to analyze the results. Information of related literatures were analyzed. Results: Finally, 3,715 articles were included. The number of published articles and the number of references increased annually. The research fields included medical imaging, critical care medicine, cardiology, etc. The United States has published more documents in this field than other countries and has shown the highest rate of cooperation with other countries. Among the top 10 research institutions with the largest number of publications, 5 are from France and 3 are from the United States. There are many authors from China in the top 10 published studies. Among the top 10 journals with the largest number of published articles, 5 journals are top journals in the field of critical care medicine. Among the top 10 keywords, there are 5 of ultrasound specialty and 2 of critical care medicine. Conclusions: Researches on the use of ultrasound in critical care units are mainly concentrated in several developed countries in Europe and the United States. Chinese research institutions should perform more studies in this field and increase cooperation with institutions from other countries.

RESUMEN

Introduction: DNA genotyping from plasma is a useful tool for molecular characterization of NSCLC. Nevertheless, the false-negative rate justifies the development of methods with higher sensitivity, especially in difficult-to-reach peripheral lung tumors. Methods: We aimed at comparing molecular analysis from the supernatant of guide sheath flush fluid collected during radial-EndoBronchial UltraSound (r-EBUS) bronchoscopy with plasma sampling and tumor biopsies in patients with peripheral NSCLC. The DNA was genotyped using high-throughput sequencing or the COBAS mutation test. There were 65 patients with peripheral lung tumors subjected to concomitant sampling of guide sheath flush supernatant, plasma tumor DNA, and tumor biopsy and cytology using r-EBUS. There were 33 patients (including 24 newly diagnosed with having NSCLC) with an identifiable tumor mutation in the primary lesion selected for the comparative analysis. Results: Guide sheath flush-based genotyping yielded a mutation detection rate of 61.8% (17 of 24 mutated EGFR, one of two ERBB2, one of one KRAS, one of one MAP2K, one of four MET, and zero of one STK11), compared with 33% in plasma-based genotyping (p = 0.0151). Furthermore, in eight of 34 r-EBUS without tumor cells on microscopic examination, we were able to detect the mutation in four paired guide sheath flush supernatant, compared with only two in paired plasma. Conclusion: The detection of tumor DNA in the supernatant of guide sheath flush fluid collected during r-EBUS bronchoscopy represents a sensitive and complementary method for genotyping NSCLC.

RESUMEN

Background: With the popularity of high-resolution computed tomography (HRCT), more and more pulmonary nodules are being discovered. Video-assisted thoracoscopic surgery (VATS) has become the first choice for surgical treatment of pulmonary nodules. The use of accurate preoperative localization is crucial for successful resection in VATS. At present, there are many kinds of preoperative localization methods, but there are certain disadvantages. This study aimed to evaluate the feasibility and safety of mixed reality (MR)-guided pulmonary nodules localization, which is a new method that can benefit patients to a greater extent. Methods: By constructing an animal model of pulmonary nodules localization, 28 cases of pulmonary nodules were located by MR-guided localization. We recorded the localization accuracy, localization time, insertion attempts, and incidence of complications related to localization under MR-guidance. Results: All 28 nodules were successfully located: the deviation of MR-guided localization was 5.71±2.59 mm, localization time was 8.07±1.44 min, and insertion attempts was 1. A pneumothorax and localizer dislodgement occurred in 1 case, respectively. Conclusions: Since preoperative localization is critical for VATS resection of pulmonary nodules, we investigated a new localization method. As indicated by our study, MR-guided localization of pulmonary nodules is feasible and safe, which is worthy of further research and promotion. We have also registered corresponding clinical trials to further investigate and help to improve our understanding of this technique.

RESUMEN

BACKGROUND: Endobronchial ultrasound-guided (EBUS) transbronchial needle aspiration (TBNA) has significantly improved the diagnostic workup for intrathoracic lymphadenopathies. More recently, EBUS intranodal forceps biopsy (IFB) has been developed in an attempt to maximize diagnostic yield by providing additional tissue. In this study, we aimed to assess the improvement of diagnostic yield with EBUS-TBNA combined with EBUS-IFB, compared to EBUS-TBNA alone. METHODS: Consecutive patients who had 19-G EBUS-TBNA and EBUS-IFB from August 30, 2018, to September 28, 2021, were included. Four senior pathologists retrospectively analyzed, independently and blindly, first, only the EBUS-TBNA samples (cell block), then, at least 1 month later, both samples from EBUS-TBNA and from EBUS-IFB together. RESULTS: Fifty patients were included in the study and 52 lymph nodes were analyzed. Diagnostic yield was 77% (40/52) for EBUS-TBNA alone and 94% (49/52) when combined with EBUS-IFB (p = 0.023). Malignancy was diagnosed with EBUS-TBNA combined with EBUS-IFB in 25/26 cases (96%), versus 22/26 (85%) with EBUS-TBNA alone (p = 0.35); and 4/5 (80%) versus 2/5 (40%) for lymphoma specifically. Kappa interobserver agreement was 0.92 for EBUS-IFB and 0.87 for EBUS-TBNA alone. Nonmalignant condition was diagnosed with EBUS-TBNA combined with EBUS-IFB in 24/26 cases (92%), versus 18/26 (69%) for EBUS-TBNA alone (p = 0.07). CONCLUSION: The use of EBUS-IFB combined with 19-G EBUS-TBNA improves the mediastinal lymph node diagnostic yield However the benefit appears to be mainly restricted to nonmalignant histology.

RESUMEN

Immune checkpoint inhibitors (ICIs) have become the standard treatment for many types of cancer. After several years of using these therapies, many adverse events related to ICIs have been observed. Dermatologic toxicities such as nonspecific morbilliform rash, vitiligo, Stevens-Johnson syndrome/toxic epidermal necrolysis, and more rarely, lichenoid eruptions have been described in the literature. We report 2 cases of pustular lichenoid eruptions, 1 in a patient with nonsmall cell lung carcinoma and 1 in a patient with metastatic melanoma, induced by pembrolizumab and nivolumab, respectively. The 2 patients were treated with topical corticosteroids, and complete healing of lesions was slowly obtained. Due to the severity of the cutaneous eruptions, pembrolizumab and nivolumab were discontinued. We identified 6 cases of pustular lichenoid eruptions induced by ICIs in the published literature and in the French Pharmacovigilance Database and reviewed their main clinical features and courses.

RESUMEN

BACKGROUND: Although the endobronchial valves (EBV) were successfully developed as treatment for severe emphysema, its main complication, pneumothorax, remained an important concern. OBJECTIVE: To assess whether the placement of Zephyr© endobronchial valves throughout 2 procedures instead of 1 minor the frequency of pneumothorax without lowering the benefits of such treatment. METHODS: This retrospective study was conducted in 15 pulmonology department in France. All the patients met the inclusion criteria of the recommendation set by the expert panel on the Endoscopic Lung Volume Reduction (ELVR) updated in 2019. As recommended, all the scan were analyzed with the StratX© (PulmonX Corporation, Redwood city, CA) protocol, and completed by a Chartis© (PulmonX Corporation, Redwood city, CA) in case of questionable fissure. During the first procedure, all but the most proximal sub-segment of the targeted lobe were occluded. One month after, EBV were placed in the bronchus of the last subsegment. All patients were evaluated before and 3 months after the second procedure. RESULTS: Between March 2019 and December 2020, 96 patients received EBV treatment. 12 patients (12.5%) presented a pneumothorax (3 after the 1st step and 9 after the 2nd procedure). Beside pneumothorax, the main adverse event was exacerbation (10.4%) and pneumonia (4.1%). No death were reported. Significant improvement were found for FEV1 (14.6 ± 25.3%), RV (- 0.69 ± 2.1 L), 6MWT (34.8 ± 45.9 m), BODE Score (-1.41 ± 1.41pts), and mMRC scale (-0.85 ± 0.7pts). These results are compared not only to the results previously published using the usual approach but also to our previous publication evaluating the 2-step approach. Some patients presented authentic segmental atelectasis despite infralobar treatment. CONCLUSION: Placing EBV during 2 procedures instead of one led to a significant decrease of post treatment pneumothoraces without increasing the rate of other complications. It does not seem to alter the benefits of such therapy for severe emphysema. These results must be confirmed by launching a multicenter, prospective, randomized, controlled study to compare the frequency of pneumothorax and the efficacy of this new approach with the usual one-time procedure.

RESUMEN

Background: The detection of pulmonary nodules significantly impacts the lives and mental health of patients. Although the 2020 National Comprehensive Cancer Network (NCCN) guidelines recommend scheduled surveillance for nodules ≤8 mm, patients often opt to have their nodules surgically removed. Methods: A cross-sectional questionnaire was administered to patients with small pulmonary nodules who presented to a local grade 3 hospital with small pulmonary nodules and decided to receive surgery versus prescribed monitoring. The questionnaire included four aspects: (I) patient characteristics; (II) nodule-specific knowledge; (III) doctor-patient communication; and (IV) nodular-specific distress. Nodular-specific distress was measured by the Impact of Event Scale-Revised (IES-R). Results: A total of 234 (69%) patients responded to the survey and were included in the final analysis. Poor performance in activities of daily living (ADLs), the presence of solid nodules, multifocal disease, and a family history of lung cancer were significantly associated with reported anxiety. Most notably, facilitating patient choice for surgery was the computed tomography (CT) scan results, with reference to lung nodule size and number of nodules, where concerns related to lung nodule, cancer risk, and fear of surgery or death had a significant psychological impact on patients. Conclusions: In this cohort of patients who elected to have their small pulmonary nodules surgically removed, we identified key factors underlying their anxiety toward guideline recommended surveillance. Our findings will be useful for clinicians when discussing treatment options with their patients.

RESUMEN

In the era of increasing availability of high-resolution chest computed tomography, the diagnosis and management of solitary pulmonary nodules (SPNs) has become a common challenging clinical problem. Meanwhile, surgical techniques have improved, and minimally invasive approaches such as robot- and video-assisted surgery are becoming standard, rendering the palpation of such lesions more difficult, not to mention pure ground-glass opacities, which cannot be felt even in open surgery. In this article, we explore the role of bronchoscopy in helping surgeons achieve successful minimally invasive resections in such cases.

RESUMEN

Background: Patients undergoing flexible bronchoscopy under local anesthesia usually experience anxiety before and during the procedure. Different non-pharmacological techniques, including music and hypnosis, are used to distract patients' attention, and to reduce anxiety. The new technique "virtual reality hypnosis (VRH)", defined as a hypnotic induction suggestion delivered by personalized virtual reality software, can generate a simulation of a lifelike environment. No study has described the use of VRH during bronchoscopy. The objective is to investigate the anxiety reducing effect and the satisfaction of patients, physicians, and nurses using VRH during bronchoscopy. Methods: VRH was proposed to all patients who experienced anxiety before undergoing flexible bronchoscopy under local anesthesia. Local anesthesia was performed using 5% lidocaine spray only. No sedation was used. After the procedure, patients, physicians and nurses filled a standardized satisfaction form. Results: Twenty consecutive patients who reported pre-procedure anxiety were included. The sex ratio was 16 women/4 men, the median age was 65 years. Eight patients (40%) had undergone a previous bronchoscopy under local anesthesia. The median duration of the procedure was 10 minutes, and all procedures were completed. The median level of anxiety of patients decreased from 9/10 before the procedure to 4/10 during the procedure. The median satisfaction rate regarding the use of VRH was 10/10. All patients agreed to use VRH again in case of a new bronchoscopy procedure. Conclusions: This preliminary report has shown that VRH was useful to reduce patients' anxiety during bronchoscopy under local anesthesia. VRH was easily implemented in the routine practice.

RESUMEN

BACKGROUND: Various advanced bronchoscopy methods have been developed to reach peripheral lung lesions (PLL). In a large cohort, we aimed to assess a standardized procedure of first-line radial-endobronchial ultrasound (r-EBUS) and virtual bronchoscopy planner for the diagnosis of peripheral lung cancer. METHODS: This retrospective, single center study included patients who had r-EBUS-guided bronchoscopy for the diagnosis of a PLL between 2008 and 2019. Cases without a final diagnosis of cancer or follow-up were excluded. RESULTS: Between 2008 and 2019, 2735 patients had a r-EBUS procedure, among whom 1627 had a final diagnosis of cancer and were included in the present study. Over the 12-year study period, r-EBUS became the first-line endoscopic procedure to assess PLL (25% as first-line bronchoscopy in 2008 vs. 92% in 2019). The frequency of the bronchus sign decreased from 2009 to 2019 (100% to 80%; p = 0.001), whereas US visualization of the lesion remained stable (88%). The median number of biopsies increased from two (2008 to 2014) to four (2015 to 2019) (p < 0.0001), with the same diagnostic efficiency (74% total and 80% when a bronchus sign was present). Of the 651 adenocarcinomas, molecular analysis was possible in 86%. PD-L1 expression analysis was possible in 81% of cases. During the study period, the lifetime of the radial probe increased from 57 procedures to 77 procedures/probe. CONCLUSION: Because r-EBUS and VB planner is easy to perform under local anesthesia, inexpensive and efficient it can be used as a first-line procedure to assess peripheral lung cancer.
