About this study
The purpose of this study is to compare the diagnostic accuracy and complication rate between low-dose computed tomography-guided and standard-dose computed tomography-guided lung biopsy.
Read the detailed description
With the comprehensive usage of computed tomography examination, patients are more and more aware of the radiation dose of computed tomography. Concerns over the potential for radiation induced malignancies have increasingly been published in the scientific literature and reported in the popular press. The risk is highest for younger patients, who have more radiation-sensitive tissues and longer life expectancies than adults. Recently, the United States Food and Drug Administration announced an initiative to reduce unnecessary radiation exposure from medical imaging. At present, low-dose computed tomography protocol is widely used for the diagnosis of cardiovascular and cerebrovascular diseases.
Computed tomography-guided lung biopsy is widely used for diagnosis of lung nodules and masses. However, it requires repeating scanning to guide the needles, which inevitably increases the radiation dose. Therefore, low-dose protocol was also used in the computed tomography-guided lung biopsy procedure.
The purpose of this study is to compare the diagnostic accuracy and complication rate between low-dose computed tomography-guided and standard-dose computed tomography-guided lung biopsy.
- Being tested
- Low-dose protocol computed tomography, Standard-dose protocol computed tomography

What is being measured
The primary outcome is the main question the study is designed to answer.
Diagnostic accuracy
Diagnostic accuracy is defined as the biopsy diagnosis matches with the final diagnosis. The final diagnosis is made according to the surgical or follow-up findings.
Measured: From the date of randomization until the date of first documented final diagnosis, assessed up to 24 months
Secondary outcomes (1)
Complication
Biopsy-related complications mainly include pneumothorax and hemoptysis. Complications is evaluated by computed tomography scan and clinical symptoms.
Measured: From the date of randomization until the date of first documented biopsy-related complication, assessed up to 1 day.

Questions about this trial
What is this clinical trial studying?
A study testing Low-dose protocol computed tomography and Standard-dose protocol computed tomography in people with Lung Cancer, Adenocarcinoma and Lung Inflammatory Pseudotumor, run by Xuzhou Central Hospital at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 4 Jun 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
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?
Diagnostic accuracy (time frame: From the date of randomization until the date of first documented final diagnosis, assessed up to 24 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 NCT02971176, which also lists 14 linked publications.
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.
