Irreversible Electroporation for Recurrent Pelvic Tumors

Official title: Irreversible Electroporation (IRE) of Recurrent Pelvic Tumors: the PELFIRE Study.

Run by Amsterdam UMC, location VUmc · NCT07782164 · Data updated 2026-11-12

This study tests whether using irreversible electroporation (IRE) is safe and helps control recurrent pelvic tumors in adults who can’t have other local treatments.

Is this trial a fit for you?

Likely a good fit

Adults with measurable recurrent pelvic tumors unsuitable for surgery, thermal ablation, or radiotherapy, confirmed by pre-treatment imaging.

Probably not a fit

Patients whose tumors do not respond to IRE or who experience unacceptable procedures-related risks may not benefit.

What this trial studies

This is a single-center observational cohort using a registry that blends past and future cases. It includes adults with recurrent pelvic tumors treated with IRE who have no other local options available. The study collects retrospective data from December 2012 through April 2025 and will prospectively enroll new cases to compare safety and local tumor control. Primary focus is on safety; secondary aims assess how well IRE can limit tumor recurrence. Patients receive the IRE procedure as the intervention, with outcomes tracked over time.

Why it matters

Potential benefit: If successful, patients may experience safer treatment and better control of pelvic tumor recurrence where other options are not feasible.

How similar studies have gone: Previous studies on IRE for pelvic or nearby tumors have shown potential for local control in selected patients, but evidence remains limited and context-specific, making this approach relatively novel in this setting.

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;
