Lung cancer is the leading cause of cancer-related death in Denmark and the world. The increase in CT examinations has led to an increase in detection of pulmonary nodules divided into solid and subsolid (including ground glass and part solid). Risk factors for malignancy include age, smoking, female gender, and specific ethnicities.

Bronchoscopy has a low risk of complications when diagnosing peripheral lung lesions suspected of malignancy, however the procedures do not always determine a diagnosis. Several modalities have been invented to improve the diagnostic yield, including radial endobronchial ultrasound and electromagnetic navigation, which are currently used by several departments in Denmark. Augmented fluoroscopy, CT-guided bronchoscopy and robotic bronchoscopy are not yet available in Denmark, but may improve the diagnostic work-up, as argued in this review.

New developments in the imaging of lung cancer.

Radiological and nuclear medicine methods play a fundamental role in the diagnosis and staging of patients with lung cancer. Imaging is essential in the detection, characterisation, staging and follow-up of lung cancer. Due to the increasing evidence, low-dose chest computed tomography (CT) screening for the early detection of lung cancer is being introduced to the clinical routine in several countries.

ERS International Congress 2023: highlights from the Clinical Techniques, Imaging and Endoscopy Assembly.

The Clinical Techniques, Imaging and Endoscopy Assembly is involved in the diagnosis and treatment of several pulmonary diseases, as demonstrated at the 2023 European Respiratory Society (ERS) International Congress in Milan, Italy. From interventional pulmonology, the congress included several exciting results for the use of bronchoscopy in lung cancer, including augmented fluoroscopy, robotic-assisted bronchoscopy and cryobiopsies. In obstructive lung disease, the latest results on bronchoscopic treatment of emphysema with hyperinflation and chronic bronchitis were presented.

A Stepwise Approach for Performing Ultrasound Guided Transthoracic Lung Biopsy.

Diagnosing patients with radiological lung lesions, especially those suspected of having primary lung cancer, is a common and critical clinical scenario. When selecting the most suitable invasive procedure to establish a diagnosis in these cases, a delicate balance must be struck between achieving a high diagnostic yield, providing staging information, minimizing potential complications, enhancing the patient experience, and controlling costs. The integration of thoracic ultrasound as a routine clinical tool in respiratory medicine has led to increased awareness and utilization of ultrasound-guided invasive techniques in chest procedures, including transthoracic biopsies.

Radial Endobronchial Ultrasound and Electromagnetic Navigation Bronchoscopy with Fluoroscopy for the Diagnosis of Peripheral Lung Lesions.

Diagnosing lung cancer using a flexible bronchoscope is a safe procedure with a very low risk of complications. Bronchoscopy has high diagnostic accuracy for endobronchial lesions, but it falls short when sampling peripheral lesions. Therefore, several modalities have been invented to guide the bronchoscope to the lesion and confirm the location of the tumor before tissue sampling.

Transbronchial Lung Cryobiopsy for Diagnosing Interstitial Lung Diseases and Peripheral Pulmonary Lesions - A Stepwise Approach.

Transbronchial lung cryobiopsy (TBLC) is an invasive procedure increasingly implemented during the last decade as an alternative to video-assisted thoracic surgery lung biopsy (SLB) for diagnosing interstitial lung diseases (ILDs). The indication for TBLC has primarily been to sub-classify a specific ILD subtype when this cannot be achieved on the basis of a preceding multidisciplinary team discussion. Although SLB is considered the gold standard for establishing a histological diagnosis, TBLC has been gradually suggested as the first-choice histological diagnostic modality in patients with unclassified ILDs due to a comparable diagnostic yield with SLB, but superior to SLB in terms of complications, including mortality.

Endobronchial Ultrasound for the Screening of Pulmonary Embolism in Patients with Suspected Lung Cancer: A Prospective Cohort Study.

Background: Patients with lung cancer exhibit increased risk of pulmonary embolism (PE). While the contrast phase of computed tomography of the chest in the diagnostic work-up of suspected chest malignancy does not allow reliable detection of PE, it may be feasible to screen for present PE during endobronchial ultrasound (EBUS) examination.

Objectives: The aim of this study was to establish if screening during EBUS for PE in patients with suspected lung cancer is feasible and if positive findings are predictive of PE.

Does the Addition of Radial Endobronchial Ultrasound Improve the Diagnostic Yield of Electromagnetic Navigation Bronchoscopy? A Systematic Review.

Background: Lung cancer is the leading cause of cancer-related death worldwide. Early diagnosis is crucial to increased survival rates. Radial endobronchial ultrasound (rEBUS) and electromagnetic navigation bronchoscopy (ENB) have been developed for the diagnosis of small lung lesions.

Lung ultrasound assessment for pneumothorax following transbronchial lung cryobiopsy.

Background: Iatrogenic pneumothorax is a common and clinically important transbronchial cryobiopsy (TBCB) complication. A study was conducted to assess the diagnostic accuracy and clinical impact of immediate post-procedure lung ultrasound for diagnosing iatrogenic pneumothorax in patients suspected of interstitial lung disease (ILD) undergoing TBCB.

Study Design And Methods: In patients undergoing TBCB due to suspected ILD, lung ultrasound of the anterior surface of the chest was performed immediately after the TBCB procedure prior to extubation.
