“…Nevertheless, ENB exhibits higher specificity and comparable sensitivity when contrasted with VBN. 3 The biopsy site is determined based on the pre-procedural CT images. An electromagnetic sensor is placed around the patient's chest to track the current position of the biopsy tools and compare them with the previously obtained 3D images of the airways.…”

IntroductionA minimally invasive approach in the diagnosis of peripheral pulmonary lesions may pose a challenge for thoracic surgeons when selecting the most appropriate technique. Electromagnetic navigation bronchoscopy (ENB) is an innovative technique used in the diagnosis of lung tumors.AimEvaluation of the merits of ENB in patient manifesting undiagnosed pulmonary and mediastinal lesions, while concurrently investigating its influence on the determination of the ultimate therapeutic strategy.Case studyThe 73-year-old male patient with a suspicious lung mass was admitted to the hospital for diagnosis and subsequent treatment. The patient underwent an invasive diagnosis of lung and mediastinum using ENB with cryobiopsy. The histopathological examination revealed adenocarcinoma and lymphoma cells, ultimately guiding the initiation of appropriate therapeutic measures.Results and DiscussionAmong the available methods, those with the highest diagnostic yield and safety should be chosen. Precise diagnosis of pulmonary lesions holds paramount importance for guiding appropriate treatment in cases of suspected malignancy.ConclusionsENB with cryobiopsy proves effective diagnosis in case of peripheral lesions that are difficult to access for classical techniques.

“…We previously demonstrated that the use of the ENB technique is a safe, effective method to increase the diagnostic accuracy of peripheral lung lesions ( 32 ). Verifying that sampling by ENB can be used reliably to study the microbiome of patients with sMPLC has several potentially important implications.…”

Microbes and microbiota dysbiosis are correlated with the development of lung cancer; however, the airway taxa characteristics and bacterial topography in synchronous multiple primary lung cancer (sMPLC) are not fully understood. The present study aimed to investigate the microbiota taxa distribution and characteristics in the airways of patients with sMPLC and clarify specimen acquisition modalities in these patients. Using the precise positioning of electromagnetic navigation bronchoscopy (ENB), we analyzed the characteristics of the respiratory microbiome, which were collected from different sites and using different sampling methods. Microbiome predictor variables were bacterial DNA burden and bacterial community composition based on 16sRNA. Eight non-smoking patients with sMPLC in the same pulmonary lobe were included in this study. Compared with other sampling methods, bacterial burden and diversity were higher in surface areas sampled by bronchoalveolar lavage (BAL). Bacterial topography data revealed that the segment with sMPLC lesions provided evidence of specific colonizing bacteria in segments with lesions. After taxonomic annotation, we identified 4863 phylotypes belonging to 185 genera and 10 different phyla. The four most abundant specific bacterial community members detected in the airway containing sMPLC lesions were Clostridium, Actinobacteria, Fusobacterium, and Rothia, which all peaked at the segments with sMPLC lesions. This study begins to define the bacterial topography of the respiratory tract in patients with sMPLC and provides an approach to specimen acquisition for sMPLC, namely BAL fluid obtained from segments where lesions are located.

“…It enables the location of the probe introduced by the bronchoscope, which is detected in the electromagnetic field generated by a board placed under the patient. ENB makes it possible to reach and sample even relatively small and peripheral lesions with lower complication rates (Dionisio, 2012;Wang Memoli et al, 2012;Gex et al, 2014;Qian et al, 2020;Dziedzic et al, 2021). However, this method is ex-pensive, time-consuming and currently is available only in selected institutions.…”

Lung cancer is the leading cause of cancer-related mortality worldwide. Early diagnosis of lung cancer is hampered by the absence of specific symptoms and the lack of a widely recognised cost-effective screening programme. Acquisition of a tumour tissue sample for morphological and molecular genetic examination is of paramount importance for cancer diagnosis. We describe diagnostic challenges for early-stage lung cancer and their possible current solutions. Liquid biopsy is a relatively new technology that was developed for evaluation of tumour-related circulating genetic material. Recent achievements in data processing provide more opportunities for wider implementation of Next Generation Sequencing (NGS) in clinical practice. This article summarises available data on the current and future role of liquid biopsy in the management of lung cancer. We also present an ongoing Latvian lung cancer study that focuses on integration of liquid biopsy with comprehensive clinical data utilising advantages of information technologies.
