Demographic features, clinical characteristics, and prognostic factors of non-epithelial ovarian tumors at Princess Noorah Oncology Center, National Guard Hospital, Jeddah, Saudi Arabia.

OBJECTIVES:To reveal the demographic features, prognostic factors, and tumor characteristics of patients with non-epithelial ovarian tumors (NEOTs). METHODS:This cross-sectional study was performed using data from all female patients diagnosed with NEOT (germ cell [GC], sex cord-stromal cells [SCSC], sarcoma, and small cell carcinoma) from 2002 to 2017 at Princess Noorah Oncology Center, National Guard Hospital Jeddah, Saudi Arabia. RESULTS:Forty patients with NEOTs were identified. There were equal percentages of GC (45%) and SCSC (45%) origin tumors, and these were the most common histological types. The remaining tumors were sarcomas. Germ cell tumors were more common in younger patients, while SCSC tumors were more frequent in the older age group. CONCLUSION:The findings for protective and risk factors were inconclusive. Patients with GC tumors had better survival outcomes than those with the other subtypes.
