MR imaging of pulmonary lung nodules during one lung flooding: first morphological evaluation using an ex vivo human lung model

ConclusionSuperior conditions with new features of lung MRI were found during lung flooding with an unrestricted visualization of malignant nodules and clear demarcation of intra-pulmonary structures. This could lead to new applications of MR-based pulmonary interventions such as laser or focused ultrasound-based thermal ablations.

In this report, both patients had lung mass accompanied by cough that lasted for>2 weeks, and were admitted to hospital for further diagnosis and treatment to clarify the nature of the mass. To make a definite diagnosis, EBUS-TBNA examination was performed under general anesthesia. Both patients had no salient past history. Diagnosis: Case 1 was diagnosed as tumor or pneumonia based on the right lung shadow. Case 2 was diagnosed with squamous cell carcinoma of the right lung with right hilar lymph node metastasis. The diagnostic results of both patients were based on pathological examination of tissues obtained by EB...

Multiple biomarkers are under evaluation to guide the use of immune checkpoint inhibitors in non –small-cell lung cancer (NSCLC), including programed death ligand 1 (PD-L1) tumor cell staining. We have developed a new approach that accurately quantifies PD-L1 status and identifies multiple mutations by using a single bronchoscopy specimen. A novel molecular marker was identified to detect the presence of malignant cells in radial endobronchial ultrasound bronchial brushings from NSCLC (n = 15) and benign (n = 13) nodules by quantitative real-time RT-PCR (RT-qPCR).

Conclusion: Our findings indicate accurate PD-L1 assessment of cytology specimens may be obtained by EBUS when cell block specimens have adequate cellular content for assessment. False negative results may be seen in inadequate specimens (

AbstractPurpose of ReviewThe landscape of lung cancer therapy has completely shifted in the last decade. From the surge of targeted therapy to the resurrection of immunotherapy, the need for adequate lung tissue specimen is critical to evaluate tumor specimens for predictive biomarkers for both types of therapies, hence, the importance of obtaining several samples via endoscopic bronchial ultrasound performed by pulmonologists or thoracic surgeons. Moreover, these novel therapies have also been associated with respiratory side effects which will require prompt evaluation and aggressive management by pulmonologists, oncolog...

CONCLUSION: Our results support pathologic assessment of N1 lymph nodes in patients with stage Inon-small cell lung cancer considered for stereotactic body radiotherapy, with the greatest benefit in patients with central and T2 tumors. Diagnostic evaluation with endoscopic bronchial ultrasound should be considered in the evaluation of stereotactic body radiotherapy candidates. PMID: 26792491 [PubMed - as supplied by publisher]
