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.

Primary Outcome Measures:
  • Correlation between DICER1 mutations and miRNA pathways with outcomes using descriptive analysis [ Designated as safety issue: No ]

Estimated Enrollment: 50
Study Start Date: April 2012
Estimated Primary Completion Date: June 2012 (Final data collection date for primary outcome measure)
Detailed Description:


  • 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.
