NCT07782164

Brief Summary

The goal of this single-center observational cohort study, based on a registry combining retrospectively and prospectively collected data, is to investigate the short- and long-term effects of irreversible electroporation (IRE) in men and women over the age of 18 who receive IRE for recurrence of pelvic tumors not suitable for other local treatment options such as surgery, thermal ablation, and radiotherapy. The main question it aims to answer is whether IRE is safe in this population, and secondarily, whether it is effective in controlling local tumor recurrence.

Outcome Measures

Primary Outcomes (2)

  • Incidence and Severity of Adverse Events (CTCAE v5.0)

    Safety of IRE, assessed by the rate and severity of adverse events per procedure and per patient, graded according to the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.

    Assessed up to 5 years.

  • Incidence and Classification of Nerve Injury (Seddon Classification)

    Nerve injuries related to IRE, assessed per procedure and per patient, classified according to Seddon's classification as neurapraxia, axonotmesis, or neurotmesis.

    Assessed up to 5 years.

Secondary Outcomes (5)

  • Overall survival (OS) per patient.

    Assessed up to 10 years

  • Progression-free survival (PFS; per patient analysis)

    Up to 10 years

  • Distant tumor progression-free survival (DPFS) per patient.

    10 years

  • Local tumor progression-free survival (LTPFS) per patient and per tumor.

    10 years

  • Technical success

    IRE procedure duration (actual treatment phase): 30 minutes to 2 hours

Other Outcomes (2)

  • Length of Post-procedural Hospital Stay

    From end of procedure to hospital discharge, assessed up to 30 days.

  • Tumor markers

    Baseline to 10 years

Sampling MethodNon-Probability Sample
Study Population

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.

You may qualify if:

  • 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;

You may not qualify if:

  • 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;
