Others

Basic objectives -Others

To determine the relationship between the grade of ovarian immature teratoma cases using existing grading systems and grade of ovarian immature teratoma by the existing grading system and the expression of Oct4 in the excised specimen.
To clarify the relationship between the expression of Oct4 in explanted specimens and the prognosis in patients with ovarian immature teratoma who did not receive postoperative adjuvant chemotherapy.
To clarify the relationship between Oct4 expression in explanted specimens and prognosis in patients with ovarian immature teratoma who received postoperative adjuvant chemotherapy.
