Recruitment status was Active, not recruiting
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.
Childhood Germ Cell Tumor
Leydig Cell Tumor
Genetic: RNA analysis
Genetic: gene expression analysis
Genetic: mutation analysis
Genetic: reverse transcriptase-polymerase chain reaction
Other: laboratory biomarker analysis
Other: medical chart review
|Official Title:||DICER1 Mutations and miRNA in Ovarian and Testicular Sex Cord Stromal Tumors of Childhood|
- Correlation between DICER1 mutations and miRNA pathways with outcomes using descriptive analysis [ Designated as safety issue: No ]
|Study Start Date:||April 2012|
|Estimated Primary Completion Date:||June 2012 (Final data collection date for primary outcome measure)|
- 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.
