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 Results may not be published yet.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
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This status has not been confirmed recently, so it may be out of date.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 international registry collects medical images and health data from people with liver cancer or liver metastases who received a procedure called combined portal and hepatic vein embolization (PVE/HVE). The procedure blocks two sets of veins in the liver to encourage the healthy part to grow larger, potentially making surgery possible for tumors that were previously too risky to remove. Researchers aim to identify which patients benefit most and how safe the technique is.

What this could mean

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

Active substance
combined portal and hepatic vein embolization (PVE/HVE)
What this could lead to
If the data show that PVE/HVE reliably makes more liver tumors removable, this technique could become a standard step before surgery for people with initially unresectable liver cancer.
What could go wrong
This is an observational registry, not a controlled trial, so it can only suggest associations, not prove the technique works. Results depend on the quality and completeness of data from many hospitals.
