Surgical evaluation remains the most reliable method for definitive disease staging. And as many as 30% of patients with early-stage ovarian epithelial carcinoma are on the rise at later stages of full staging surgery.The 2014 NCCN guideline suggests that for fertility-preserving surgery for ovarian epithelial carcinoma, the scope of surgery should be consistent with full staging surgery, except for preservation of the uterus and healthy adnexa, to exclude patients with potentially occult advanced disease. In contrast, the UK NICE guideline does not recommend systematic lymph node dissection and only advocates palpation assessment of lymph nodes and biopsy of suspiciously enlarged lymph nodes, arguing that full staging surgery increases the incidence of intraoperative and perioperative complications (e.g. increased intraoperative bleeding, postoperative lymphatic cyst formation). In addition, the healthy ovary should be carefully and thoroughly examined, and if there is any abnormality in its appearance, dissection should be performed and biopsy and frozen pathology may be performed if necessary; if the appearance is completely normal, dissection is not necessary to avoid the possibility of causing infertility or premature ovarian failure. Also, for the choice of surgical approach, it can be done by an experienced gynecologic oncologist through laparoscopy.
