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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 study looks at whether irreversible electroporation (IRE) can safely and effectively treat recurrent pelvic tumors in people who cannot have surgery, radiation, or other local treatments. IRE uses electrical pulses to destroy cancer cells without cutting or heating tissue. Researchers will track side effects, nerve damage, and how long patients live without the tumor growing back.

What this could mean

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

Active substance
Irreversible electroporation (IRE), a procedure using electrical pulses to destroy tumor cells
What this could lead to
If IRE proves safe and effective, it could offer a new treatment option for people with recurrent pelvic tumors who have run out of standard choices like surgery or radiation.
What could go wrong
This is a small observational study, so results may not apply broadly. IRE carries risks like nerve injury, and its long-term effectiveness is still uncertain.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Consecutive patients treated with irreversible electroporation (IRE) for recurrent pelvic tumors at Amsterdam UMC starting from December 2012, identified from a dedicated institutional registry. Patients had recurrent pelvic disease not amenable to other local treatment options (surgery, stereotactic body radiotherapy, or thermal ablation), as determined by a multidisciplinary tumor board including medical oncology, radiation oncology, surgical oncology, diagnostic and interventional radiology, and pathology.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Measurable disease described on pre-treatment imaging (CT/MRI/PET-CT) (max 6 weeks prior); * IRE of a recurrent pelvic tumor; * Unsuitable for other local therapies (surgery/stereotactic body radiation therapy) as described during the multidisciplinary tumor board; Exclusion Criteria: * If the treated tumor was biopsied directly prior to MWA and pathology proves the lesion to represent a benign entity; * Inadequate or insufficient data registered; * Inadequate or insufficient follow-up;
