Contamination of Testicle Tissue by RT-PCR in Participants With Solid Tumors (TESTIMAR)

March 26, 2015 updated by: University Hospital, Clermont-Ferrand

Study About Contamination of Testicle Tissue by RT-PCR in Children With Solid Tumors

For prepubertal patients, cryopreservation of testicular tissue is the only option available to preserve their fertility before cancer treatment. But testicular autograft raises the issue of the risk of reintroduction of potentially malignant cells. The aim of our study is to develop a specific and sensitive method for residual disease detection in the testicular tissue from patients treated for a solid tumor during infancy, whose fertility may have been compromised by treatments and who benefited of testicular tissue cryopreservation.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

Detailed Description

Some solid tumors have high risk of metastatic localization including in testis. There is concern over the possible presence of malignant cells in testicular tissue that could cause a recurrence of the primary disease after reimplantation. Thus, the possibility of testicular tissue involvement needs to be evaluated with sensitive molecular methods.

Based on our experience in detection by RT-PCR of minimal residual disease (MRD) in neuroblastoma since 1994 [Tchirkov et al. 2003] and in testicular tissue cryopreservation since 2012, we want to develop a specific and sensitive method for residual disease detection by RT-PCR in order to evaluate the tumor contamination of testicular harvested tissue.

Study population: We chose 3 models of pediatric solid tumors with high risk of metastases and which often require sterilizing treatments (chemo and/or radiotherapy): neuroblastoma, Ewing tumor and alveolar rhabdosarcoma. We will use four tumor cells lines: IMR32 and SK-NSH for neuroblastoma; RD-ES for Ewing tumor; RH-30 for rhabdosarcoma. We plan to use 20 fragments per line.

Study duration: 12 months Study design: Testicular tissue without known malignancy but with a condition warranting a biopsy (fertility assessment) will be harvested.

The harvested testicular cortex will be treated to recover all viable sperm and then, we use remaining tissue to be contaminated with tumor cells lines. Then, detection of the specific transcript will be done by RT-PCR in fresh tissue and after freeze/thaw. Total RNA will be extracted with the TRI-reagent and qRT-PCR will be performed using the "TaqMan" technology.

Primary endpoint: to reach a sensitivity about 1/106 cells.

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

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

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.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
November 1, 2014

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Anticipated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
