Comparison of the Prognostic Outcome between High-Grade Ovarian Sertoli-Leydig Cell Tumors (SLCTs) and Low-Grade SLCTs
The purpose of the current study was to compare prognostic outcomes between patients with high-grade ovarian Sertoli-Leydig cell tumors (SLCTs) and those with other low-grade SLCTs. We retrospectively reviewed medical records for 24 patients pathologically diagnosed with SLCTs between 2006 to 2019 at two institutions. The patients were grouped according to pathological grade: SLCT was classified as grade 1, well differentiated; grade 2, intermediated differentiated; or grade 3, poorly differentiated (Meyer's classification). Statistical analysis was performed to compare survival outcomes according to pathological grade. The median patient age was 42.5 years (range 16-75). Eighteen patients (75%) were International Federation of Gynecology and Obstetrics stage I, and none were diagnosed in stage IV. Nine patients (37.5%) were grade 3, and 15 patients (63.5%) were grades 1-2. When comparing clinical baseline characteristics of the grade 1-2 group with those of the grade 3 group, only serum CA125 level at diagnosis was significantly higher in the grade 3 group (38.34 vs. 382.29,
