About this study

Official title: Three-Dimensional Printing of Navigational Template in Localization of Small Pulmonary Nodule: A Prospective, Randomized, Controlled, Non-inferiority Trial

The trial is to evaluate the efficacy and safety of three-dimensional printed navigational template in the clinical application of small peripheral lung nodule localization.

Read the detailed description

Localization of small lung nodule is challenging due to the difficulty of nodule recognition during VATS. A three-dimensional printed navigational template was designed to aid percutaneous lung nodule localization, and its feasibility has been confirmed in previous study. The trial was conducted to confirm the non-inferiority of template-guided method to conventional CT-guided method in terms of localization accuracy.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • template-guided localizationDevice

    Based on CT data, digital model of the navigational template was created using CAD software and imported to 3D printer. The navigational template serves as a guider to the localizer in lung nodule localization.

  • CT-guided localizationOther

    Percutaneous lung nodule localization was conducted under the real-time guidance of CT scan. This is the conventional method of transthoracic lung nodule localization.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Accuracy of Lung Nodule Localization

    Localization accuracy was defined by the localizer deviation between the hookwire and the center of the target nodule. (The deviation was measured using CAD software after downloading the CT images from the Picture Archiving and Communication Systems.)

    Measured: From the time of completing final CT scan, assessed up to 2 days.

Secondary outcomes (3)
  1. Procedural Duration of the Nodule Localization

    Procedural duration was derived from CT scan parameters, which was calculated as the time length between the initial and final scan.

    Measured: From the time of completing final CT scan, assessed up to 1 hour.

  2. Radiation Dose

    Radiation dosage was read on the monitor screen of CT scanner and converted to effective dosage.

    Measured: From the time of completing final CT scan, assessed up to 1 hour.

  3. Complication Rate

    Pnuemothorax related to lung nodule localization

    Measured: From the time of completing final CT scan, assessed up to 2 days.

Questions about this trial

What is this clinical trial studying?

A study testing template-guided localization and CT-guided localization in people with Lung Neoplasm and Thoracic Surgery, Video-Assisted, run by Chang Chen 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 5 inclusion and 2 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 19 Dec 2018. 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?

Yes. Results are posted in the registry (first posted 1 Oct 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Accuracy of Lung Nodule Localization (time frame: From the time of completing final CT scan, assessed up to 2 days.). 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 NCT02952261, which also lists 2 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 19 Dec 2018.
