title: Mitotic count, nuclear atypia, and immunohistochemical determination of Ki-67, c-myc, p21-ras, c-erbB2, and p53 expression in granulosa cell tumors of the ovary: mitotic count and Ki-67 are indicators of poor prognosis.
abstract: In spite of extensive research, the behavior of granulosa cell ovarian tumors remains unpredictable and is complicated by the lack of prognostic factors in early-stage disease. Forty patients with granulosa cell tumors were identified from tumor registries and data were analyzed for patient outcome. Mitotic count and nuclear atypia were determined at time of histological review. Paraffin-embedded archival tumor tissues from 32 of 40 patients were available, and immunohistochemical testing for Ki-67, c-myc, p21-ras, c-erbB2, and p53 was performed on archival tissues. Results were correlated with patients' outcome. Mitotic count and Ki-67 were found to be negatively associated with survival in granulosa cell tumors. Nuclear atypia, c-myc, p21-ras, c-erbB2, and p53 were not found to be of prognostic significance.
