Cost–effectiveness of endobronchial percutaneous biopsy compared with transthoracic biopsy for diagnosis of peripheral lung lesions


Aim: This study compares the cost–effectiveness of radial endobronchial ultrasound (R-EBUS; Olympus Medical Systems Group, Tokyo, Japan) and electromagnetic navigation (ENB) to transthoracic needle biopsy (TTNB) to attain a confirmative diagnosis of the suspect lung lesions(s). Methods: The National Lung Screening Trial enrolled over 50,000 people aged 55–74 years with at least a 30-pack/year smoking history, in fairly good health and not symptomatic of lung disease. The study found low-dose computed tomography of the chest resulted in a 20% lower chance of dying from lung cancer compared with those who had chest x-rays. Approximately 25% of the low-dose computed tomography-screened patients had a positive screen requiring confirmation of the lung lesion. Using an estimate of 5.2 million annual chest CT scans in the USA as a basis for the number of patients seeking a confirmative result before being recommended for surgery for possible benign lung lesions our study seeks to identify the most cost-effective biopsy protocol to reduce costs, and deliver improved diagnostic accuracy. Results:
