Objectives: After studying the article entitled “Comparison of Endobronchial Ultrasound and Computed Tomography With Fluoroscopy in the Guidance of Lung Cancer Biopsies: A Literature Review,” you will be able to:
Describe the techniques and equipment used for ultrasound-guided endobronchial lung biopsies
Describe the sonographic image characteristics of lung lesions
Discuss the relative advantages and limitations of ultrasound-guided endobronchial lung biopsies versus guidance using computed tomography (CT) with fluoroscopy
The median survival of patients following diagnosis of lung cancer is
1–2 months 3–6 months 6–12 months 12–18 months
The most important predictor for the resectability and prognosis for lung cancer is
Accurate staging Lesion size Lesion location Lesion proximity to trachea
The gold standard to diagnose lung cancer is
Endobronchial biopsy Ultrasound-guided endobronchial biopsy CT with fluoroscopy-guided biopsy Open biopsy
Sonographically, a lung cancer lesion will appear
As a dark, homogeneous structure As a dark, heterogeneous structure As a bright, heterogeneous structure As a bright structure with a “snowstorm” appearance
The diagnostic yield for ultrasound-guided endobronchial lung cancer biopsy for lesions larger than 20 mm in size is typically
>50% >70% >85% >95%
The highest accuracy for ultrasound-guided endobronchial lung cancer biopsy occurs for lesions in the
Left upper lobe Left lower lobe Right upper lobe Right middle lobe
Ultrasound-guided transbrachial biopsies are typically done using a transducer operating at
30 MHz 20 MHz 10 MHz 5 MHz
The most common complication reported for ultrasound-guided endobronchial lung cancer biopsies is
Pneumothorax Pleural effusion Bleeding Hemoptysis
The diagnostic yield for CT with fluoroscopy-guided lung cancer biopsies is typically
85%–95% 75%–85% 65%–75% 55%–65%
The overall reported complication rate for CT with fluoroscopy-guided lung cancer biopsies is approximately
3% 5% 8% 11%
