Study to Evaluate the Efficacy of Percutaneous Cryoablation for Renal Tumours < 4cm in Patients Who Are Not Candidates for Partial Nephrectomy (CRYOREIN)

April 7, 2016 updated by: University Hospital, Strasbourg, France

Prospective Study to Evaluate the Efficacy of Percutaneous Cryoablation for Renal Tumours < 4cm in Patients Who Are Not Candidates for Partial Nephrectomy

The main objective is to evaluate the oncologic efficacy of percutaneous cryoablation of renal tumors smaller than 4 cm in patients with renal cancer that cannot be offered a partial nephrectomy. The oncologic outcome will be assessed by the presence or absence of residue or recurrence during a follow-up by MRI performed the first 12 months (M1, M3, M6, M12).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

Patients should have the following characteristics:

  • About 75 years, or

  • Whatever the age:

    • A context of family-type tumor (VHL, hereditary carcinoma, tubulo-papillary ...);
    • or solitary kidney, when the tumor is not easily accessible for nephron-sparing surgery: Malignant centro-hilar or intra-parenchymal;
    • or in a local recurrence (single or multiple) after partial nephrectomy (within a limit of 3 tumors to be treated);
    • or in a subject with impaired renal function and therefore at risk of severe renal insufficiency (risk defined by a creatinine clearance below 30 ml / min by MDRD formula);
    • and who do not present any contra-indication for cryoablation treatment.

The tumor(s) should meet the following criteria:

  • Presence of one to three solid tumors of the native renal parenchyma with a largest diameter less than (or equal to) 40 mm, which corresponds to a maximum volume of about 32 cc, as measured by MRI.
  • A preoperative MRI is essential since this technique presents a higher sensitivity. This control will also give more consistency to the evaluation of the radiological semiology at follow-up.
  • And its/their location(s) will be accessible to a percutaneous approach.

The search of metastases, including a thoracic CT scan, should be negative.

Exclusion Criter ia:

  • - Partial nephrectomy feasible in good technical and oncologic conditions in patients under 75 years and in the absence of family tumors.
  • Contraindication to any form of sedation.
  • Irreversible coagulopathy
  • Tumor> 4cm
  • Contraindication to MRI or gadolinium (proven allergy). NB: Patients with a glomerular filtration rate below 30 ml/min/1, 73 m2 will be injected with a single dose of the macrocyclic gadolinium with the highest thermodynamic stability (Dotarem or Prohance), given the united recommendations of AFSSAPS and EMA (European Medicines Agency) [45]. On the contrary, the linear molecules of gadolinium, due to their lower stability, will be contra-indicated because of the risk of systemic nephrogenic fibrosis (FNS).
  • Recurrence on the same location after a procedure performed out of the thermoablation protocol.
  • Biopsy proven benign tumor
  • Predominantly cystic tumor, defined by a necrotic content constituting over one third of tumor volume
  • Presence of endo-venous extension, of proven secondary extensions, visceral or in the lymph nodes (especially lung). In this regard, a thoracic CT scan will be routinely required before treatment, according to the recommendations of urological societies.
  • Psychiatric disorders and adults under guardianship
  • Pregnancy or breastfeeding
  • Minor patients
  • Legal safeguard
  • Participation in another clinical trial

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Suspicious contrast enhancement and progression in size of the cryolesion detected by MRI
Time Frame: 1 year
The success of cryoablation will be declared if the control at 1 year shows no suspicious contrast enhancement (the suspicious character is defined by significant contrast uptake (>15%) and heterogeneous or nodular or crescent-shape contrast enhancement) and if the cryolesion is not progressing in size compared to early post-ablation control (M1).
