Oocyte cryopreservation in two women with borderline ovarian tumor recurrence

A comprehensive review of the new FIGO classification of ovulatory disorders

BACKGROUND

The World Health Organization (WHO) system for the classification of disorders of ovulation was produced 50 years ago and, by international consensus, has been updated by the International Federation of Gynecology and Obstetrics (FIGO).

OBJECTIVE AND RATIONALE

This review outlines in detail each component of the FIGO HyPO-P (hypothalamic, pituitary, ovarian, PCOS) classification with a concise description of each cause, and thereby provides a systematic method for diagnosis and management.

SEARCH METHODS

We searched the published articles in the PubMed database in the English-language literature until October 2022, containing the keywords ovulatory disorders; ovulatory dysfunction; anovulation, and each subheading in the FIGO HyPO-P classification. We did not include abstracts or conference proceedings because the data are usually difficult to assess.

OUTCOMES

We present the most comprehensive review of all disorders of ovulation, published systematically according to the logical FIGO classification.

WIDER IMPLICATIONS

Improving the diagnosis of an individual's ovulatory dysfunction will significantly impact clinical practice by enabling healthcare practitioners to make a precise diagnosis and plan appropriate management.

Reproductive outcomes in women opting for fertility preservation after fertility-sparing surgery for borderline ovarian tumors

PURPOSE

What are the reproductive outcomes of women who had fertility preservation (FP) using either oocyte or embryo vitrification after fertility-sparing surgery (FSS) for a borderline ovarian tumor (BOT)?

METHODS

A retrospective, single-center cohort study was conducted between January 2013 and December 2021. Patients with BOT who resorted to FP by vitrifying oocytes or embryos were included. Both clinical and reproductive parameters were reviewed. The primary outcome was live birth.

RESULTS

In total, thirteen patients who performed 31 FP cycles were included. Of those, six patients achieved eight live births after a mean follow-up period of 79 months. Three further pregnancies are still ongoing. All pregnancies/live births were obtained without using their cryopreserved oocytes or embryos.

CONCLUSION

Women who had FSS for BOT have favorable prospects of live offspring, even without the need to use their cryopreserved material. Fertility preservation in patients with BOT has to be considered as a tool to mitigate the risk of infertility that may arise in case of BOT recurrence requiring castrating surgery.

Fertility sparing treatment for bilateral borderline ovarian tumor: a case report and management strategy explication

A bilateral adnexal mass with suspected carcinosis could be a challenging experience for the gynecologist especially in fertile age and in patients with a desire for pregnancy. A 26-year-old patient who came to the outpatient clinical observation for bilateral, multilocular pelvic masses, with more than 4 papillary structures, color score 2, hypomobile compared to the uterus and rectum, respectively of 65 and 68mm in maximum diameter, free liquid in the abdomen and suspected of ovarian neoplasm. Positive tumor markers and a strong desire of a fertility sparing treatment (FST). A 2-step surgical approach managed to perform a diagnosis of bilateral ovarian borderline tumor with implants and a fertility sparing surgery. Harvesting and cryopreserving oocytes prior to the cytoreductive intervention was successfully performed.

Successful delivery after in vitro fertilization-embryo transfer in a woman with metachronous primary cancer of ovary and endometrium: a case report

BACKGROUND

The appearance of malignancies at various times in the same individual, excluding metastases of the initial primary cancer, is termed multiple primary cancers. Double primary gynecological cancers cause inevitable damage to female reproductive function, and the preservation of fertility in such patients remains a challenging issue as relatively few cases have been reported. This case report provides management options for dual primary ovarian and endometrial cancers, including the choice of ovulation induction protocols, considerations during pregnancy and parturition, with the aim of providing assistance to clinicians.

CASE PRESENTATION

We report a case of a 39-year-old woman with primary infertility and a medical history of right-sided ovarian mucinous borderline tumor with intraepithelial carcinoma, left-sided ovarian mucinous cystadenoma and endometrial cancer, who successfully conceived with in vitro fertilization-embryo transfer (IVF-ET) after three different ovulation induction protocols. During her pregnancy, she was complicated by central placenta praevia with placental implantation and eventually delivered a healthy female infant by caesarean section at 33 gestational weeks.

CONCLUSIONS

For patients with double primary gynecological cancers who have an intense desire for fertility, the most appropriate oncological treatment should be applied according to the patient's individual situation, and fertility preservation should be performed promptly. Ovulation induction protocol should be individualized and deliberate, with the aim of ensuring that the patient's hormone levels do not precipitate a recurrence of the primary disease during induction of ovulation and maximizing fertility outcomes. In addition, the risk of postpartum hemorrhage due to placental factors cannot be neglected in such patients.

Obstetric outcomes after conservative management of ovarian borderline tumors in women of reproductive age: A single center experience

OBJECTIVE

The main goal of fertility-sparing treatment is pregnancy followed by live birth (i.e., successful pregnancy). The principal objective of our study was to evaluate the successful pregnancy rate in patients with borderline ovarian tumors (BOTs) after conservative treatment. The second goal was to evaluate the safety of the conservative approach.

STUDY DESIGN

110 patients with BOT were retrospectively evaluated. All patients underwent surgical treatment, sparing the uterus and part of at least one ovary.

RESULTS

The median age was 28 years (range 17-40 years). Serous and mucinous tumors were found in 63 (57%) and 34 (31%) women, respectively. FIGO stage I, II, and III was diagnosed in 101 (91.8%), 3 (2.7%), and 6 (5.5%) patients, respectively. The 3- and 5-year progression-free survival was 82.5% and 78.2%, respectively. Recurrent disease was treated conservatively in 14 women, whereas 3 patients underwent radical surgery. Fifty-six (50.9%) patients got pregnant and had at least one live birth. A total of 83 children were born. A significant difference in the successful pregnancy rate was found in patients diagnosed ≤ 35 years vs. > 35 years old (55.6% vs. 9.1%, respectively; p = 0.003). Surgical approach (laparoscopy vs. laparotomy) did not influence the chance of childbirth. Pre-term delivery constituted 6.25% of all births.

CONCLUSIONS

Fertility-sparing surgery should be proposed to young women wishing to preserve fertility. The rate of spontaneous pregnancy is approximately 50%.The risk of relapse is significant but always of borderline histology and may be successfully treated by the second surgery.

Fertility preservation after fertility-sparing surgery in women with borderline ovarian tumours

OBJECTIVE

To present a case series of women with borderline ovarian tumours (BOTs) who underwent oocyte vitrification in addition to fertility-sparing surgery.

STUDY DESIGN

Observational study of all women referred to a French fertility preservation unit between 2015 and 2019 for counselling regarding a fertility preservation (FP) strategy after BOT fertility-sparing surgery. All eligible women underwent one or more cycles of controlled ovarian stimulation (COS) using an antagonist protocol, followed by oocyte retrieval. Metaphase II (MII) oocytes were vitrified.

RESULTS

Twenty-five women with BOTs were referred during the study period. Among them, 11 women underwent at least one cycle of COS. One hundred and seven MII oocytes were vitrified. The mean number of vitrified MII oocytes per woman was 9.7 (standard deviation 5.2). Five live births were reported during follow-up of four women with vitrified oocytes: three spontaneous pregnancies, one in-vitro fertilization cycle with fresh embryo transfer, and one live birth after return of vitrified oocytes.

CONCLUSION

Conservative surgery for BOTs offers a high spontaneous pregnancy rate but has a higher risk of relapse than radical treatment. Furthermore, women who undergo conservative BOT surgery have a higher risk of surgery-induced premature ovarian failure. Oocyte cryopreservation after COS appears to be an effective technique after the conservative management of BOTs in women of reproductive age. Although the available short-term data are reassuring, further long-term studies evaluating the safety and cost-effectiveness of this systematic FP strategy after BOT fertility-sparing surgery are required.
