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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 completed study looked at 44 patients who had lung cancer surgery to understand how the arteries in the lungs can vary from person to person. Using CT scans and 3D models, researchers mapped these variations to help surgeons avoid complications during lobectomy. The goal was to gather knowledge that could make future surgeries safer and more precise.

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 could help surgeons better plan lung cancer surgeries by understanding common artery variations, potentially reducing complications.
What could go wrong
This is a small, observational study with only 44 patients, so findings may not apply to everyone. It does not test a new treatment or directly improve outcomes.

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The investigators studied patients having undergone VATS lobectomy for stage I-II lung cancer at the Amiens University Hospital's Department of Thoracic Surgery between October 2012 and March 2014. We performed 3D reconstruction of the pulmonary arterial tree on the CT angiography data set acquired during preoperative work-up.

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

Inclusion Criteria: * Any major patient aged 18 years and over who has undergone oncological lung lobectomy for non-small-cell lung cancer located in the thoracic surgery department of the University Hospital of Amiens. * Nosologic criteria and related to acts: The pathology has already been diagnosed or suspected, and the surgical indication has been validated in the Multidisciplinary Thoracic Oncology Concertation Meeting according to national recommendations. * These patients will be collected in a database already referenced in the register of the establishment of the University Hospital of Amiens under the reference DRCI T38 Exclusion Criteria: * Criteria relating to the population: * Patient under guardianship or curatorship * Pathology Criteria: Patient with no pulmonary neoplastic disease, patient with locally advanced or metastatic bronchopulmonary cancer * Criteria relating to the acts: the criteria altering the surgical specimen and thus its anatomical study: patient having had an extemporaneous examination, patient with the antecedents of ipsilateral pulmonary surgery and / or need of decortication
