Community hospital experience using electromagnetic navigation bronchoscopy system integrating tidal volume computed tomography mapping

STUDY
Raval AA, Amir L. Community hospital experience using electromagnetic navigation bronchoscopy system integrating tidal volume computed tomography mapping. Lung Cancer Manag. 2016;5(1):9-19.

OVERVIEW

  • + SPiN™ was used to diagnose suspicious peripheral lung nodules
  • + First 50 consecutive patients referred for bronchoscopy or surgery after positive CT scan
  • + 48% of patients had no bronchus sign (23/48)
  • + More than half of lesions were <20mm in diameter
  • + Average nodule size was 19.3mm

OBJECTIVE
Measure the total diagnostic yield relative to location and size of the lung lesion when using the TV-EXP-mapped EMN system for the first 50 consecutive patients (61 lesions) in the absence of radial-endobronchial ultrasound (EBUS), fluoroscopic navigation or rapid on-site cytology (ROSE).”

82%

of patients were successfully and accurately diagnosed

AUTHORS’ CONCLUSION
“…this new technology has significantly changed our approach to suspicous PPN. Increased confidence in our ability to accurately reach smaller PPNs has been meaningful in support of our desire to
completely address the patient’s spectrum of biopsy options. The ability to collect staging samples and to accurately biopsy the lesion in a single procedure is encouraging to streamline patient care.”

KEY FINDINGS

  • + Diagnostic yield increased to 88% when a bronchus sign was present
  • + “The diagnostic yield for our first 25 patients was 80% (20/25). The diagnostic yield for the next 23 patients was 87% (20/23) revealing a promising trend toward improvement due to a learning curve with the technology”
  • + Multiple malignancies for nodules diagnosed, leading to earlier stage diagnoses
  • + “The ability to collect staging samples and to accurately biopsy the lesion in a single procedure is encouraging to streamline patient care”
