The Impact of Electromagnetic Navigational Bronchoscopy on a Multidisciplinary Thoracic Oncology Program

Area of Science:

• Pulmonology
• Oncology
• Medical Imaging

Background:

• The Leo W. Jenkins Cancer Clinic implemented a multidisciplinary approach for thoracic tumors.
• Electromagnetic navigational bronchoscopy (ENB) was introduced in 2012 as an advanced diagnostic tool.
• ENB utilizes CT imaging and magnetic guidance for tissue sampling and fiducial marker placement.

Purpose of the Study:

• To evaluate the impact of ENB on the diagnosis of early-stage versus late-stage lung cancers.
• To compare the use of bronchoscopy versus interventional radiology for fiducial marker placement before and after ENB implementation.
• To assess pneumothorax rates associated with fiducial marker placement methods.

Main Methods:

• Comparative analysis of lung cancer stage distribution before and after ENB introduction.
• Assessment of fiducial marker placement methods (bronchoscopy vs. interventional radiology) pre- and post-ENB.
• Statistical comparison using Fisher's exact test for cancer staging, marker placement, and pneumothorax rates.

Main Results:

• A significant increase in early-stage lung cancer diagnoses post-ENB introduction (P<.0001).
• Increased utilization of bronchoscopy for fiducial marker placement after ENB implementation (P<.0001).
• Lower pneumothorax rates with bronchoscopy-guided marker placement compared to interventional radiology (P<.001).

Conclusions:

• ENB integration into thoracic oncology programs facilitates earlier lung cancer diagnosis.
• ENB enables safe, same-procedure fiducial marker placement for radiation therapy.
• The use of ENB may enhance treatment safety and reduce time to therapy initiation.
