NCT ID NCT06119867

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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

Summary

This trial compares two methods of examining colon cancer tissue after surgery: the European method, which relies solely on pathologists, and the Japanese method, which involves surgeons in finding lymph nodes. The goal is to see if the Japanese method is as accurate as the European method in detecting cancer spread to lymph nodes, which is crucial for staging and treatment planning. The study will involve 430 patients who have had colon cancer surgery.

What this could mean

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

Active substance
Japanese pathological investigation
What this could lead to
If the Japanese method proves as accurate as the European one, it could offer an alternative approach for staging colon cancer, potentially improving treatment decisions.
What could go wrong
This is a comparison of diagnostic methods, not a treatment, so its direct impact on patient outcomes may be limited. The Japanese method's accuracy is unproven, and results may vary between labs.
