Trial summary

Currently there is no consensus on post procedural follow up imaging following percutaneous cryoablation of renal tumors. Interpretation of conventional contrast enhanced imaging (CT and MRI) during follow up can be very challenging. Read more about this study

About this study

Official title: Follow up After Percutaneous MR-guided Cryoablation of Small Renal Masses.

Currently there is no consensus on post procedural follow up imaging following percutaneous cryoablation of renal tumors. Interpretation of conventional contrast enhanced imaging (CT and MRI) during follow up can be very challenging. The objective of this study is to evaluate the feasibility of early evaluation of the therapeutic effect by performing early follow up imaging after percutaneous MR-guided cryoablation of pT1a renal cell carcinoma using 111In-Girentuximab-DOTA SPECT CT imaging.

Read the detailed description

With the growing number of small renal masses (SRMs) detected, a growing interest in minimal invasive treatment options for these lesions is seen as they come with several advantages compared to partial nephrectomy. Current guidelines state that patients with a small renal mass unfit to undergo surgery, should be considered for minimal invasive ablative treatment. Although percutaneous cryoablation is shown to be a safe and effective therapy for SRM, there is no consensus on post procedural follow up imaging which should be aimed at evaluation of therapeutic effect of the intervention and the early detection of residual and recurrent disease. Also interpretation of conventional contrast enhanced imaging (CT and MRI) during follow up can be very challenging due to contrast enhancement not necessarily indicating residual or recurrent disease.

The objective of this study is to evaluate the feasibility of early evaluation of the therapeutic effect by performing early follow up imaging after percutaneous MR-guided cryoablation of pT1a renal cell carcinoma 111In-Girentuximab-DOTA SPECT CT imaging.

Therefore, before cryoablation, a targeting 111In-Girentuximab-DOTA SPECT CT scan is performed. Additional functional 111In-Girentuximab-DOTA SPECT CT scan 4-6 weeks after percutaneous MR-guided cryoablation of small renal masses is performed. The latter will take place in case of proven targeting on the pre procedural 111In-Girentuximab-DOTA SPECT CT scan. Standard 1 and 3 months follow up MRI after treatment is performed.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Predictive value.

    Positive predictive value and negative predictive value of 111In-Girentuximab-DOTA SPECT 4-6 weeks after intervention as confirmed on subsequent conventional follow up imaging (contrast enhanced MRI).

    Measured: Up to at least 3 months following initial treatment (cryoablation).

Questions about this trial

What is this clinical trial studying?

An observational study of Carcinoma, Renal Cell, run by Radboud University Medical Center at 1 site in Netherlands.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 11 Jan 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Predictive value. (time frame: Up to at least 3 months following initial treatment (cryoablation).). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Jan 2019.
