About this study

Official title: DICER1 Mutations and miRNA in Ovarian and Testicular Sex Cord Stromal Tumors of Childhood

RATIONALE: Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors identify biomarkers related to cancer.

PURPOSE: This research trial is studying genes in tumor samples from younger patients with ovarian or testicular sex cord stromal tumors.

Read the detailed description

OBJECTIVES:

  • To assess the role of DICER1 mutations and miRNA pathways in the etiology and progression of ovarian or testicular sex cord stromal tumors.

OUTLINE: Archived tumor tissue samples are analyzed for D1CER1 mutation and mRNA expression by reverse-transcriptase polymerase chain reaction (RT-PCR) and laser micro dissector. Results are then correlated with medical data, including age at diagnosis, diagnosis, pathology report, presenting symptoms, family history, treatment, outcome, and length of follow-up, when available.

Being tested
RNA analysis, gene expression analysis, mutation analysis, reverse transcriptase-polymerase chain reaction, laboratory biomarker analysis
Keywords
Leydig cell tumor, ovarian stromal cancer, childhood malignant testicular germ cell tumor, childhood malignant ovarian germ cell tumor
Medical subject headings
Leydig Cell Tumor, Ovarian Neoplasms, Testicular Neoplasms, Ovarian Germ Cell Cancer

Questions about this trial

What is this clinical trial studying?

An observational study of Childhood Germ Cell Tumor and Leydig Cell Tumor, run by Children's Oncology Group.

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

Who may be eligible to take part?

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 14 Jul 2016. Status can change between updates, so confirm with the study contact before making plans.

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?

Correlation between DICER1 mutations and miRNA pathways with outcomes using descriptive analysis. 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 14 Jul 2016.
