Traditionally, ovarian serous carcinomas (OSCs) have been graded using a 3-tiered system, as well differentiated, moderately differentiated, and poorly differentiated. Recently, a 2-tiered system has been proposed depending on the nuclear atypia and mitotic count. The dualistic pathway of ovarian serous carcinogenesis with accumulating molecular genetic evidence forms the basis for this grading system.
