What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looked at over 1,000 patients who had a lung nodule marked with a special trimmed wire before surgery. The goal was to see if this technique raised the risk of a collapsed lung (pneumothorax) compared to using dye alone. Researchers found that the trimmed wire did not increase the risk, offering a safer option for guiding surgery.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this study could help doctors choose safer methods for guiding lung nodule removal, reducing the chance of a collapsed lung.
What could go wrong
This is a retrospective observational study, not a controlled trial, so it can't prove cause and effect. Results may not apply to all hospitals or patients.

Who is studied

The final analysis cohort included 1,072 POCTGL procedures. The procedures resulted in 1,567 evaluable lung nodules after the initial exclusion. Demographics: The median age was 55 years (IQR, 48-63). The cohort was predominantly women (74.6%) and nonsmokers (86.3%). Lesion Characteristics: The median lesion size was 6.5 mm (IQR, 5.0-8.0) , with a median depth from the pleura of 19 mm (IQR, 10.0-30.0). Procedure Type: Most procedures (90.3%) were for initial VATS , and the majority involved a single lesion (65.5%).

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Consecutive series of patients who underwent Preoperative Computed Tomography-Guided Lung Nodule Localization (POCTGL) at our medical center between September 2015 and January 2022. * All included procedures were performed in patients who subsequently underwent Video-Assisted Thoracoscopic Surgery (VATS) lung resection on the same day. Exclusion Criteria For the primary Generalized Estimating Equations (GEE) analysis: * Nodules localized after a pneumothorax event occurred (n=59) were excluded. Exclusion Criteria For the Propensity Score Matching (PSM) analysis: * Nodules localized after a pneumothorax event (n=59). * Nodules that were not the first localized nodule during the POCTGL procedure (n=495). * Nodules associated with a previous ipsilateral VATS (n=16).
