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.
