About this study
Official title: A New Guide for Our Guided-Bronchoscopy: The Use of Cone-Beam CT to Enhance Navigation and Diagnostic Yield of RP-EBUS and Hybrid Bronchoscope for Peripheral Lung Nodules Suspicious for Malignancy: A Pilot Study
This pilot clinical trial studies how well cone-beam computed tomography (CBCT) works in guiding bronchoscopy in patients with lung lesions. CBCT during bronchoscopy may help doctors to biopsy lung lesions that are harder to reach.
Read the detailed description
PRIMARY OBJECTIVES:
- To describe the feasibility of using CBCT as an additional aid to guided-bronchoscopy with radial probe endobronchial ultrasound (RP-EBUS)/hybrid scope for the diagnosis of peripheral lung nodules.
SECONDARY OBJECTIVES:
- Describe the proportion of patients with peripheral nodules undergoing bronchoscopy in whom the lesion is identified by RP-EBUS (RP-EBUS-navigation yield) and confirmed with CBCT.
II. Describe the proportion of patients with peripheral nodules undergoing bronchoscopy in whom the lesion is identified by RP-EBUS and samples are diagnostic (diagnostic yield-RP-EBUS).
III. Describe the proportion of patients with peripheral nodules undergoing bronchoscopy in whom the lesion is identified by RP-EBUS, samples were non-diagnostic, and CBCT prompted further tool re-location (i.e. change of needle angle, change of tool) leading to diagnosis.
IV. Describe the proportion of patients with peripheral nodules undergoing bronchoscopy in whom the lesion is not identified by RP-EBUS, and CBCT-aided navigation allowed the operator to reach the lesion (CBCT-added navigation yield).
- Describe the proportion of patients with peripheral nodules undergoing bronchoscopy in whom the lesion is not identified by RP-EBUS and CBCT-aided navigation allowed the operator to reach the lesion and obtain a diagnosis (CBCT-added diagnostic yield).
VI. Describe the relationship between RP-PROBE and target (contact/no contact; central/peripheral).
VII. Describe the relationship between needle tip and target (contact/no contact; central/peripheral).
VIII. Describe the influence of points 6 and 7 on diagnostic yield. IX. Describe fluoroscopy time. X. Describe estimated amount of radiation generated by CBCT use. XI. Describe bronchoscopy time (first scope in/last scope out). XII. Describe the proportion of patients in whom molecular analysis for lung cancer (i.e. EGFR, K-RAS, ALK) can be performed.

What is being measured
The primary outcome is the main question the study is designed to answer.
Feasibility based on percentage of patients where researchers can locate target and bronchoscopic tools with cone-beam computed tomography
Will be considered feasible if researchers can locate target and bronchoscopic tools with cone-beam computed tomography in at least 80% of the patients (16 out of the 20 participants) that are enrolled.
Measured: Up to 6 months
Secondary outcomes (5)
Proportion of patients with peripheral nodules undergoing bronchoscopy in different subsample
Will conduct extensive descriptive analyses of the data collected. Descriptive statistics (e.g., frequencies, ranges, means, proportions, standard deviations, and measures of skewness and kurtosis), including 90% confidence intervals will be calculated. Will closely examine distribution characteristics of the variables using box plots, histograms, and scatter plots, where appropriate.
Measured: Up to 6 months
Localization of the tip with respect to targets
Will assess the relationship between radial probe/needle tip and target. Will conduct extensive descriptive analyses of the data collected. Descriptive statistics (e.g., frequencies, ranges, means, proportions, standard deviations, and measures of skewness and kurtosis), including 90% confidence intervals will be calculated. Will closely examine distribution characteristics of the variables using box plots, histograms, and scatter plots, where appropriate.
Measured: Up to 6 months
Diagnostic yield
Will assess the influence of points 6 and 7 on diagnostic yield. Descriptive statistics (e.g., frequencies, ranges, means, proportions, standard deviations, and measures of skewness and kurtosis), including 90% confidence intervals will be calculated. Will closely examine distribution characteristics of the variables using box plots, histograms, and scatter plots, where appropriate.
Measured: Up to 6 months
Amount of radiation generated by cone-beam computed tomography use
Descriptive statistics (e.g., frequencies, ranges, means, proportions, standard deviations, and measures of skewness and kurtosis), including 90% confidence intervals will be calculated. Will closely examine distribution characteristics of the variables using box plots, histograms, and scatter plots, where appropriate.
Measured: Up to 6 months
Fluoroscopy/bronchoscopy time
Descriptive statistics (e.g., frequencies, ranges, means, proportions, standard deviations, and measures of skewness and kurtosis), including 90% confidence intervals will be calculated. Will closely examine distribution characteristics of the variables using box plots, histograms, and scatter plots, where appropriate.
Measured: Up to 6 months

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Feasibility based on percentage of patients where researchers can locate target and bronchoscopic tools with cone-beam computed tomography (time frame: Up to 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02978170, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Jun 2019; AzTrials last refreshed its copy on 7 Nov 2026.
