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 This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 explores whether detailed pain mapping and sensory tests can better capture pain patterns after lung surgery. Researchers will assess pain sensitivity around the incision and track recovery for three months. The goal is to see if these methods are practical and could help predict who develops long-term pain. Participants are men undergoing minimally invasive lung 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 could lead to better ways to predict and manage pain after lung surgery, potentially reducing chronic pain.
What could go wrong
This is a small pilot study focused on feasibility, so results may not apply broadly. The tests are observational and do not change treatment.

Inclusion Criteria: 1. Male 2. Scheduled to undergo elective thoracoscopic or robotic-assisted lung resection. 3. American Society of Anesthesiologists physical status I to III. 4. Able to understand and communicate adequately and to complete study questionnaires independently or with assistance from study staff. 5. Willing to undergo QST assessment, perioperative venous blood sampling, and postoperative follow-up. 6. Able and willing to provide written informed consent. Exclusion Criteria: 1. Definite chronic chest wall, shoulder, back, or upper limb pain with an average 2. Numeric Rating Scale score of 3 or higher during the preceding week. 3\. Definite painful neuropathic disease or long-term use of opioids or other analgesics for more than 2 weeks. 4\. Peripheral neuropathy, spinal cord disease, or other neurological disease that may substantially interfere with interpretation of QST results. 5\. Severe cognitive impairment, psychiatric disorder, communication disorder, or inability to complete questionnaires and QST assessments. 6\. Active infection, active autoimmune disease, or other disease condition that may substantially affect inflammatory protein measurements. 7\. Emergency surgery, conversion to open thoracotomy, extensive chest wall resection, or severe intraoperative complications. 8\. Any condition that, in the opinion of the investigator, makes the participant unsuitable for continued participation in the study.
