Trial summary

Disorders of Sexual Development are rare and represent a spectrum of heterogeneous pathologies. The risk of developing a malignant gonadal germ cell tumor (MGCT) exists and varies according to the etiology. The indication for prophylactic gonadectomy must be modulated and discussed for all patients. Read more about this study

About this study

Official title: DEV-GEN-RiTuGo - Assessment of Individual Gonadal Tumor Risk in Patients With Disorders of Sexual Developpment According to the Etiology.

Disorders of Sexual Development are rare and represent a spectrum of heterogeneous pathologies. The risk of developing a malignant gonadal germ cell tumor (MGCT) exists and varies according to the etiology.

The indication for prophylactic gonadectomy must be modulated and discussed for all patients. It is essential to assess each patient's individual risk.

The aim of our study is to assess gonadal tumor risk in patients with Disorders of Sexual Development according to etiology

The primary objective is to evaluate tumor risk and the indication for gonadectomy in cases of Disorders of Sexual Development according to etiology.

The secondary objectives are to evaluate the timing of gonadectomy, to monitor changes in practice over time, and to assess the contribution of imaging and/or biological tests to tumor detection.

What is being measured

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

  1. Presence or absence of gonadal tumor lesion after gonadectomy, in case of Disorders of sexual development (DSD) according to anatomo-pathological analysis.

    Datas about the gonadectomy surgical pieces performed between1990 and 2022 are reviewed for the study by Dr Frédérique Dijoud, anatomo-pathologist at the DEV-GEN CRMR in Lyon, to confirm the présence or absence of a gonadal tumor lesion, in order to avoid intra- and inter-reader interpretation bias.

    Measured: The outcome measure will be assessed and the datas reported for each patient will be collected, from birth until the study completion date, or by default until the date of death from any cause. Datas will be collected during the 10 months of the study

Questions about this trial

What is this clinical trial studying?

An observational study of Disorders of Sexual Development, run by Hospices Civils de Lyon at 1 site in France.

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 8 inclusion and 5 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 13 Apr 2025. 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 France. 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?

Presence or absence of gonadal tumor lesion after gonadectomy, in case of Disorders of sexual development (DSD) according to anatomo-pathological analysis. (time frame: The outcome measure will be assessed and the datas reported for each patient will be collected, from birth until the study completion date, or by default until the date of death from any cause. Datas will be collected during the 10 months of the study). 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 13 Apr 2025.
