Lung cancer screening: detected nodules, what next?

Since the success of the NLST study, the incorporation of lung cancer screening programs into current academic programs has been growing. Center for Medicare and Medicaid Services have acknowledged the importance and potential impact of lung cancer screening by making it a reimbursable study. Based on Fleischner Society Guidelines, many nodules will require follow-up imaging. The remainder of those nodules will need tissue to appropriately make the diagnosis. The use of bronchoscopy with transbronchial biopsy has been a standard technique for many years, but as smaller nodules need to be assessed, more advanced tools, such as endobronchial ultrasound and electromagnetic navigation are now improving the yield on the diagnosis of these smaller peripheral nodules. As electromagnetic navigation and peripheral ultrasound are significant changes from practice only 10 years ago, further advancements in the technology, such as bronchoscopic robots and advanced optical imaging tools, that are becoming available, n...
