stage I 이어도 IB 혹은 일부 IC는 양쪽 난소에 involved인데 아무리 Fertility sparing 하고싶다고해도
USO를 하는게 말이되나? 싶어서

FIGO Guideline 찾아보니

The causes of death include complications of disease (e.g.small bowel obstruction) or complications of therapy, and onlyrarely malignant transformation. The mainstay of treatment isprimary surgical staging and cytoreduction. For patients withStage I disease who want to preserve fertility, conservativesurgery with unilateral salpingo- oophorectomy can be consid-ered after intraoperative inspection of the contralateral ovaryto exclude involvement. 158 For patients with only one ovary, orbilateral cystic ovaries, a partial oophorectomy or cystectomycan be considered for fertility preservation. For all other pa-tients, total hysterectomy and bilateral salpingo- oophorectomyare recommended, with maximal cytoreduction if the disease ismetastatic.

borderline + stage I이면 intraoperative inspection of the contralateral ovary to exclude involvement

하고 나서 USO를 한다고하며

정확히는 stage IA,일부 IC에서만 고려가능한듯합니다! (unilateral)
