Survival and reproductive outcomes after fertility-sparing surgery performed for borderline epithelial ovarian tumor in Japanese adolescents and young adults: Results of a retrospective nationwide study

Oncologic and reproductive outcomes after fertility-sparing surgery for bilateral borderline ovarian tumors: A retrospective study

OBJECTIVES

To investigate the oncological safety and fertility outcomes of different fertility-sparing surgery procedures for bilateral borderline ovarian tumors (BOTs) and to identify the safest and most effective approach to help patients conceive with minimal risk.

STUDY DESIGN

A retrospective study of 144 patients (≤40 years) with pathologically confirmed bilateral BOTs were included in the study.The effects of surgery type on fertility outcome and recurrence were compared. Cox regression analysis was employed to determine potential prognostic factors. Survival analysis utilized the Kaplan-Meier method.

RESULTS

Three therapeutic modalities were applied in our study, including bilateral ovarian cystectomy (BOC; n = 29), unilateral adnexectomy + contralateral cystectomy (UAC; n = 4) and radical surgery (n = 61). Totally 33 cases (22.9 %) relapsed during the follow-up period. In 37 % of cases administered conservative surgery, relapses were diagnosed in the first 2 years. Only conservative surgery and adjuvant chemotherapy were risk factors for recurrence. Meanwhile, a pregnancy rate of 55.4 % was obtained in patients with bilateral BOTs. The pregnancy rate was slightly higher but no significant (P = 0.539) difference in patients treated with BOC (n = 17, 63 %) compared with UAC (n = 29, 55.8 %) group. GnRHa treatment significantly improved the clinical pregnancy rate in this study(P = 0.029).

CONCLUSIONS

Satisfactory pregnancy rate can be achieved after conservative surgery in patients with bilateral BOTs. BOC is worth recommending for bilateral borderline ovarian tumors and a critical factor in fertility is the preservation of maximum healthy ovarian tissue. Patients should make a pregnancy plan in 2 years after the first surgery. GnRHa increase the rate of successful clinical pregnancies.

Fertility-sparing management of stage IIIC serous borderline ovarian tumor: A case report of a 20-year follow-up

Multimodal treatment, including assisted reproductive technology, is necessary in young patients with advanced borderline ovarian tumors. However, the details of long-term follow-up cases have not been reported. In this report, a 19-year-old patient presented with a stage IIIC serous borderline tumor. The patient underwent five fertility-sparing surgeries. The tumor did not respond to any of the three lines of chemotherapy administered. Serological and radiological responses were observed following hormonal treatment with leuprorelin, followed by a fourth surgery. Before the planned fifth surgery for complete resection of both adnexa, cryopreservation of the fertilized eggs was performed. At age 36, when the disease-free interval exceeded the previous one, we proposed embryo transfer; however, she declined fertility treatment. The patient had developed rheumatoid arthritis and childbirth not a priority. The patient had lived without any evidence of disease for 7 years following the last surgery and 20 years after the initial visit.

Current limits of conservative treatment in ovarian cancer

PURPOSE OF REVIEW

Fertility-sparing surgery in ovarian cancer is an increasing need in gynecology-oncology clinical practice because of the frequent childbearing delay in developed countries. As the evidence in literature is based on observational studies, this review focuses on summarizing the most recent and relevant evidence for the conservative management of young patients with ovarian cancer.

RECENT FINDINGS

Staging surgery is mandatory in epithelial ovarian tumors. In sex cord-stromal tumors, fertility-sparing surgery is only recommended in FIGO stage IA. Due to its good prognosis, conservative treatment is possible in some cases of advanced disease of germ cell tumors and borderline tumors. Cystectomy is a reasonable option in serous borderline tumors but is not recommended in other tumor subtypes. Successful conception rates after fertility-sparing surgery ranges from 30 to 60%.

SUMMARY

Fertility-sparing surgery is a well tolerated option in young women with early-stage ovarian cancer with acceptable reproductive outcomes.

Safety of assisted reproductive techniques in gynecological cancer patients

PURPOSE OF REVIEW

Gynecological cancer is a very important cause of comorbidity and mortality in women. The current delay in motherhood is increasing the incidence of women under 40 years of age that have not yet achieved their maternity goals when they are diagnosed and standard treatment negatively impacts the reproductive potential of cancer survivors. In this review, we update the information available about the safety of fertility-sparing treatments in young gynecological cancer patients, as well as the safety and efficacy of assisted reproductive techniques (ART) in such group. We also evaluate the long-term gynecological cancer risk in women requiring ART.

RECENT FINDINGS

Although eligibility criteria continue to be very strict, there are more and more reports of fertility-sparing approaches outside of what traditionally has been considered safe. Molecular assessment is starting to be used in the selection of appropriate candidates. Data increasingly shows the long term safety and the efficacy of ART and pregnancy in these patients.

SUMMARY

Appropriate selection is key to safely preconize fertility-sparing alternatives. Because subfertility may be a result of these procedures, ART could be indicated in this setting. Neither ART nor pregnancy appear to increase recurrences or affect survival rates.
