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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tested whether sharing photos between surgeons and pathologists during head and neck cancer surgery could improve the removal of all cancerous tissue. Normally, they only talk by phone. Here, 155 patients had photos taken of their tumors and surgical margins, which were shared digitally. The goal was to see if this visual communication helps achieve a clean margin (R0 resection) more often. The study is complete, and results will show if this simple change makes a difference.

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 approach could become a standard way to improve communication during surgery, potentially leading to more complete tumor removal.
What could go wrong
This is a small, completed study testing a communication method, not a new treatment. It may not show a clear benefit over standard phone calls, and results may not apply to all hospitals.
