Fertility sparing surgery in malignant ovarian Germ cell tumor (MOGCT): 15 years experiences

Oncofertility and Fertility Preservation for Women with Gynecological Malignancies: Where Do We Stand Today?

Oncofertility is a growing medical and research field that includes two main areas: oncology and reproductive medicine. Nowadays, the percentage of patients surviving cancer has exponentially increased, leading to the need for intervention for fertility preservation in both men and women. Specifically, gynecological malignancies in women pose an additional layer of complexity due to the reproductive organs being affected. In the present review, we report fertility preservation options with a cancer- and stage-specific focus. We explore the drawbacks and the necessity for planning fertility preservation applications during emergency statuses (i.e., the COVID-19 pandemic) and comment on the importance of repro-counseling for multifaceted patients during their oncological and reproductive journey.

Spontaneous pregnancy after fertility-sparing surgery and adjuvant chemotherapy for advanced pure dysgerminoma: A case report

Key Clinical Message

Fertility-sparing surgery and appropriate adjuvant chemotherapy for advanced malignant ovarian germ cell tumors have excellent survival results and promising reproductive and obstetric outcomes.

Abstract

This case report aims to demonstrate the potential feasibility and success of fertility-sparing surgery (FSS) coupled with adjuvant chemotherapy in treating advanced malignant ovarian germ cell tumor (MOGCT), focusing on pure dysgerminoma, fertility, and achieving spontaneous pregnancy. The patient was a 23-year-old female who initially presented with complaints of abdominal distension and a palpable mass and was subsequently diagnosed with advanced MOGCT. The patient provided a complete clinical and radiological response to FSS with complete surgical staging and cisplatin-based chemotherapy (bleomycin, etoposide, and cisplatin). Despite being diagnosed with advanced MOGCT and treated with FSS and adjuvant chemotherapy, she later experienced spontaneous pregnancy, giving birth to a healthy child. This case study demonstrated the potential for successful fertility preservation and pregnancy in advanced-stage MOGCT patients treated with personalized treatment approaches. Nevertheless, a broader investigation is needed to understand the relevant complex dynamics and to ascertain whether FSS with adjuvant chemotherapy could be a reliable approach in treating advanced MOGCT.

Fertility-sparing approach to malignant ovarian germ cell tumors - Oncologic and obstetric outocome: A retrospective study

OBJECTIVE

To evaluate oncologic (such as disease-free and overall survival) and obstetric outcomes in patients diagnosed with malignant ovarian germ cell tumors (MOGCTs).

METHODS

Patients diagnosed with MOGCTs between March 2007 and February 2022 were evaluated and patients who underwent fertility sparing surgery were included in this retrospective study. The obstetric and oncologic outcomes were evaluated by collecting data up until the patient's last follow-up visit from the hospital records and patient files. The study was approved by Başkent University Institutional Review Board (KA23/124).

RESULTS

Seventy FSS patients were included in this study. The median age of the patients was 22.5 years (range: 11-37). The median follow-up time was 92.0 months (10-189). Immature teratoma was the most common histological subtype (32.9%). Bilateral involvement was detected in only one patient with immature teratoma (1.4%). The 5-year DFS rates of immature teratoma, dysgerminoma, yolk sac, and mixed germ cell histologic types were 91.1%, 94.1%, 82.4%, and 88.9%, respectively (P: 0.716). The 5-year OS rates of the same histologic types were 95.7%, 100%, 88.2%, and 88.9%, respectively (P = 0.487). All patients (100%) had a regular menstrual cycle after the completion of adjuvant treatment. The mean time between the last chemotherapy and menstruation was 4.38 months. To date, a total of 34 patients tried to conceive after the completion of disease treatment. A total of 23 (67.6%) patients conceived, resulting in 27 live births in 22 (100%) patients.

CONCLUSION

Fertility preservation should be the first treatment option in MOGCTs in young patients due to the unilateral involvement of the disease and its chemosensitive nature.

Ovarian preservation in gynecologic oncology: current indications and techniques

PURPOSE OF REVIEW

Early menopause represents a relevant clinical issue for women. Nevertheless, this issue should be balanced with the risks of ovarian metastasis, ovarian recurrence, and the risk of recurrence in hormone-sensitive gynecological cancers. The purpose of this review was to provide an overview on current indications and techniques of ovarian preservation in patients with gynecological cancers.

RECENT FINDINGS

The potential discussion about ovarian conservation could be proposed to patients with FIGO-stage IA grade 1-2 endometrioid endometrial cancer aged 40 years or less, FIGO-stage IB1-IB2 node-negative cervical cancer with squamous cell carcinoma and HPV-associated adenocarcinoma, FIGO-stage IA-IC grade 1-2 serous, endometrioid, mucinous expansile pattern ovarian cancer, any stage germ cell ovarian tumors, and FIGO-stage IA sex cord-stromal tumors. Technique to perform ovarian transposition in cervix cancer is also reported.

SUMMARY

Ovarian conservation is a surgical approach that involves preserving one or both ovaries during the treatment of gynecologic cancers. This approach has gained popularity in recent years, as it offers several benefits to the patient, including the preservation of hormonal function and fertility. The decision to perform ovarian conservation depends on several factors, such as the stage and type of cancer, the patient's age, fertility desire, and should be carefully discussed with patients.

Obstetric Results after Fertility-Sparing Management of Non-Epithelial Ovarian Cancer

PURPOSE

To assess the recurrence and birth rates among patients with non-epithelial ovarian cancer.

METHODS

The study included 146 patients with germ cell (GCT, n = 84) and sex cord-stromal tumors (SCST, n = 62), who underwent fertility-sparing surgery. Adjuvant chemotherapy was administered to 86 (58.9%) patients. Most cases (133 out of 146) were staged FIGO I.

RESULTS

The 5- and 10-year disease-free survival rates were 91% and 83%, respectively. The recurrence risk was not associated with tumor histology, stage or age. Twenty-four months after the treatment, the rate of recurrence was higher than the rate of childbearing. The childbearing rates kept rising after the treatment and exceeded the rate of recurrence after 2 years. The cumulative incidence rates of birth 36, 60 and 120 months after treatment were 13.24%, 20.75%, and 42.37%, respectively. Chemotherapy was not related to childbearing. The patients' age was related to the chance of childbearing.

CONCLUSIONS

The prognoses of GCT and SCST are similar. Close follow-ups along with contraception should be offered to women during the first two years after treatment due to the increased risk of recurrence. After this period, relapses are rare and women can safely become pregnant.

Fertility-sparing surgery: a hopeful strategy for young women with cancer

Fertility preservation in cancer patients is currently based on either assisted reproductive technology or fertility-sparing surgery. Loss of fertility may be caused by excisional surgery associated with an adnexal or uterine pathology or secondary to gonadal insufficiency caused by chemotherapy or radiation. The counseling of these patients is very important, being carried out jointly by the oncologist, gynecologist, and reproductive medicine specialist. Reproductive surgery usually requires avoiding laparotomy to significantly reduce the formation of adhesions and trauma or tissue damage. This is done using standard laparoscopic surgery or robotic surgery (computer-assisted laparoscopy), a method increasingly used and accessible to all specialists who want to maintain the fertility of their patients with various oncological diseases.

Oncology and reproductive outcomes over 16 years of malignant ovarian germ cell tumors treated by fertility sparing surgery

BACKGROUND

Malignant ovarian germ cell tumors (MOGCT) are rare and frequently occur in women of young and reproductive age and the oncologic and reproductive outcomes after fertility-sparing surgery (FSS) for this disease are still limited.

AIM

To evaluate the oncology and reproductive outcomes of MOGCT patients who underwent FSS.

METHODS

All MOGCT patients who underwent FSS defined as the operation with a preserved uterus and at least one side of the ovary at our institute between January 2005 and December 2020 were retrospectively reviewed.

RESULTS

Sixty-two patients were recruited for this study. The median age was 22 years old and over 77% were nulliparous. The three most common histology findings were immature teratoma (32.2%), dysgerminoma (24.2%), and yolk sac tumor (24.2%). The distribution of stage was as follows; Stage I, 74.8%; stage II, 9.7%; stage III, 11.3%; and stage IV, 4.8%. Forty-three (67.7%) patients received adjuvant chemotherapy. With a median follow-up time of 96.3 mo, the 10-year progression-free survival and overall survival were 82.4% and 91%, respectively. For reproductive outcomes, of 43 patients who received adjuvant chemotherapy, 18 (41.9%) had normal menstruation, and 17 (39.5%) resumed menstruation with a median time of 4 mo. Of about 14 patients who desired to conceive, four were pregnant and delivered good outcomes. Only one case was aborted. Therefore, the successful pregnancy rate was 28.6%

CONCLUSION

The oncology and reproductive outcomes of MOGCT treated by FSS are excellent. Many patients show a long survival time with normal menstruation. However, the obstetric outcome is not quite satisfactory.
