  Purpose

The study aims to determine if there are defining EBUS and confocal endoscopy features as well as exhaled alveolar gas VOC that can discriminate malignant pulmonary nodules or masses from benign etiology, thereby obviating unnecessary thoracotomy. Directly sampled alveolar gas VOC from patients with lung cancer will be compared against exhaled breath VOC for signature compounds that may complement CT in screening the population at risk.

Primary Outcome Measures:
  • Correlating pathology between EBUS, confocal microendoscopy and VOC patterns to aid in characterising malignant and benign etiology. [ Designated as safety issue: No ]

Estimated Enrollment: 60
Study Start Date: April 2011
Estimated Study Completion Date: March 2013
Estimated Primary Completion Date: March 2013 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: Olympus Ultrathin Bronchofibervideoscope (XP260F)
    The bronchovideoscope will be used together with an assisted image-guided bronchoscopic navigation software system called LungPoint®, to view lungs in a real time 3D manner.
    Other Name: Olympus Lucera Broncho Fibervideoscope (BF-XP260F)
Detailed Description:

AIMS

  1. To improve diagnostic yield of pulmonary nodule or mass by using combined approach of navigation bronchoscopy and EBUS.
  2. To determine if characteristic features of EBUS and confocal microendoscopy exist as well as VOC patterns in alveolar and exhaled gas that can aid in discriminating malignant pulmonary nodule or mass from benign etiology by correlating with pathology.
  3. To identify VOC patterns specific for lung cancer by correlating VOC from directly sampled alveolar gas and exhaled breath with pathology. Exhaled breath VOC signature may complement CT in screening population at risk.

Criteria

Inclusion Criteria:

  • All patients aged above 21 years, capable of giving consent and suspected of lung cancer with radiological lung nodules and masses.
