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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Researchers are studying whether microwave ablation, helped by a saline injection that separates the liver tumor from the diaphragm, is safe and effective for hepatocellular carcinoma. They compare this approach with surgical resection in patients whose single tumor is 5 cm or smaller and sits close to the right diaphragm. Participants in both groups receive standard care and are followed for two years to track progression-free and overall survival.

What this could mean

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

Active substance
Microwave ablation with diaphragm hydrodissection, a procedure that injects saline to protect the diaphragm during tumor heating
What this could lead to
If it works, this technique could offer a less invasive option for liver tumors near the diaphragm, potentially reducing recovery time compared with surgery.
What could go wrong
This is an observational comparison, not a randomized trial, so differences may reflect patient selection rather than the treatment itself. The technique also depends on operator skill and may not fully control tumors that touch the diaphragm.
