“…In 1997, Kim et al first reported that 13 of 21 (62%) patients who were treated with progestin alone for type I EC had an initial response to progestins ( 5 ), beginning the exploration of the criteria for the conservative treatment. At present, relevant guidelines for fertility preservation treatment of EC have been launched, including the NCCN 1 ( 6 ), the Gynecological Oncology Committee of Chinese Anti-Cancer Association ( 7 ), and the European Society of Gynecological Oncology (ESGO) ( 8 – 11 ). The main indications agreed by the above guidelines/expert consensus are as follows: - 1) Well-differentiated (grade 1) endometrioid adenocarcinoma confirmed by expert pathology review,
- 2) Disease limited to the endometrium on imaging,
- 3) Absence of suspicious or metastatic disease on imaging,
- 4) No contraindications to medical therapy or pregnancy, and
- 5) Patients should undergo counseling as the fertility-sparing option is not standard of care for the treatment of endometrial carcinoma.
