Ultra-conservative fertility-sparing strategy for bilateral borderline ovarian tumours: an 11-year follow-up

The Shared Ovary: A Multidisciplinary Discussion With Pediatric and Adolescent Gynecology

Pediatric and adolescent ovarian lesions are common and are frequently managed by both pediatric surgeons and pediatric and adolescent gynecologists. During the 2023 American Academy of Pediatric Section on Surgery meeting, an educational symposium was delivered focusing on various aspects of management of pediatric and adolescent benign and malignant masses, borderline lesions, and fertility options for children and adolescents undergoing cancer therapies. This article highlights the discussion during this symposium.

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.

Oncological and Reproductive Outcomes after Fertility-Sparing Surgery in Patients with Advanced-Stage Serous Borderline Ovarian Tumor: A Single-Center Retrospective Study

Our study aimed to analyze the prognosis and reproductive outcomes of patients with advanced-stage serous borderline ovarian tumors (SBOTs) who underwent fertility-sparing surgery (FSS). This study included patients aged ≤ 45 years diagnosed with advanced-stage (International Federation of Gynecology and Obstetrics II and III) SBOTs who were treated with FSS. Conservative surgeries were performed in 65 patients with advanced-stage SBOT with a median age of 28 years (range, 16-44 years). Nine patients had invasive implants. The median follow-up was 81.7 months. Forty-six patients (70.8%) had a relapse (median time to first recurrence, 22.8 months). Thirteen patients subsequently developed recurrence as an invasive disease, and two died due to disease progression. After multivariate analysis, age < 30 years and incomplete cytoreduction were independent risk factors for recurrence. Invasive implants and postoperative residual tumors were significantly associated with shorter disease-free survival. Of 35 patients attempting to conceive, 12 underwent assisted reproductive technology. Additionally, 19 pregnancies, including 15 full-term births, were documented. FSS provides a good chance of reproductive success in women with advanced-stage SBOT who desire fertility preservation, but it has a high recurrence rate and risk of malignancy transformation. Patients with invasive implants should be strictly selected for FSS.

Fertility-sparing surgery for borderline ovarian Brenner tumor and subsequent childbirth: First case report and a literature review

Borderline ovarian Brenner tumors are rare malignancies mainly diagnosed after menopause. A first pregnancy after fertility-sparing surgery by laparoscopic unilateral salpingo-oophorectomy was reported in a previous article. We now report the first baby birth after unilateral salpingo-oophorectomy for a borderline ovarian Brenner tumor and a review of the literature.

The challenging management of borderline ovarian tumors (BOTs) in women of childbearing age

Borderline ovarian tumors (BOTs) account for approximately 15% of all epithelial ovarian cancers. In 80% of cases the diagnosis of BOTs is done at stage I and more than a third of BOTs occurs in women younger than 40 years of age wishing to preserve their childbearing potential; the issue of conservative surgical management (fertility-sparing treatment) is thus becoming of paramount importance. At early stages, the modalities of conservative treatment could range from mono-lateral cystectomy to bilateral salpingo-oophorectomy. Although cystectomy is the preferred method to promote fertility it can lead to an elevated risk of recurrence; therefore, an appropriate counseling about the risk of relapse is mandatory before opting for this treatment. Nevertheless, relapses are often benign and can be treated by repeated conservative surgery. Besides the stage of the disease, histological subtype is another essential factor when considering the proper procedure: as most mucinous BOTs (mBOTs) are more commonly unilateral, the risk of an invasive recurrence seems to be higher, compared to serous histotype, therefore unilateral salpingo-oophorectomy is recommended. In the appraisal of current literature, this review aims to gain better insight on the current recommendations to identify the right balance between an accurate staging and an optimal fertility outcome.

Risk Factors for Recurrence of Borderline Ovarian Tumours after Conservative Surgery and Impact on Fertility: A Multicentre Study by the Francogyn Group

Introduction: Borderline ovarian tumours (BOT) represent 10–20% of epithelial tumours of the ovary. Although their prognosis is excellent, the recurrence rate can be as high as 30%, and recurrence in the infiltrative form accounts for 3% to 5% of recurrences. Affecting, in one third of cases, women of childbearing age, the surgical strategy with ovarian conservation is now recommended despite a significant risk of recurrence. Few studies have focused exclusively on patients who have received ovarian conservative treatment in an attempt to identify factors predictive of recurrence and the impact on fertility. The objective of this study was to identify the risk factors for recurrence of BOT after conservative treatment and the impact on fertility. Material and methods: This was a retrospective, multicentre study of women who received conservative surgery for BOT between February 1997 and September 2020. We divided the patients into two groups, the “R group” with recurrence and the “NR group” without recurrence. Results: Of 175 patients included, 35 had a recurrence (R group, 20%) and 140 had no recurrence (NR group, 80%). With a mean follow-up of 30 months (IQ 8–62.5), the overall recurrence rate was 20%. Recurrence was BOT in 17.7% (31/175) and invasive in 2.3% (4/175). The mean time to recurrence was 29.5 months (IQ 16.5–52.5). Initial complete peritoneal staging (ICPS) was performed in 42.5% of patients (n = 75). In multivariate analysis, age at diagnosis, nulliparity, advanced FIGO stage, the presence of peritoneal implants, and the presence of a micropapillary component for serous tumours were factors influencing the occurrence of recurrence. The post-surgery fertility rate was 67%. Conclusion: This multicentre study is to date one of the largest studies analysing the risk factors for recurrence of BOT after conservative surgery. Five risk factors were found: age at diagnosis, nulliparity, advanced FIGO stage, the presence of implants, and a micropapillary component. Only 25% of the patients with recurrence underwent ICPS. These results reinforce the interest of initial peritoneal staging to avoid ignoring an advanced tumour stage.

The Multimodal Ultrasound Features of Ovarian Serous Surface Papillary Borderline Tumor

Aim:

Ovarian serous surface papillary borderline tumor (OSSPBT) is very rare. Combined with clinical and pathological features, we aim to investigate the multimodal ultrasound features of OSSPBT.

Patients and Methods:

There were only 18 patients diagnosed with OSSPBT among the 142 patients who were diagnosed with borderline serous ovarian tumor by pathology from June 2008 to December 2020 in our hospital. Their clinical data, conventional ultrasound, two-dimensional contrast-enhanced ultrasound (2D-CEUS), three-dimensional contrast-enhanced ultrasound (3D-CEUS) characteristics, pathology, and prognosis were retrospectively analyzed.

Results:

The 18 patients had no specific clinical symptoms. Multiple implantable nodules were found in 8 patients (44.4%), ascites in 13 patients (72.2%), and elevated carbohydrate antigen 125 (CA125) in 15 patients (83.3%). After excluding 2 misdiagnosed patients from 18 patients, 26 tumors in 16 patients (6 unilateral and 10 bilateral) were studied. Conventional ultrasound findings of OSSPBT showed that large solid masses around normal ovary without capsule, and numerous small dense anechoic areas were observed in the parenchyma of the lesion, with strong speckle echo (“blizzard” sign) of varying degrees. The 2D-CEUS and 3D-CEUS showed a normal ovary in the center surrounded by a radial blood supply of OSSPBT with thick and irregular branches. Histopathologically, the papillary fibrous stalk of OSSPBT had a large number of sand bodies and tortuous dilated microvessels. All patients had no recurrence after surgery, and two of them delivered successfully through assisted reproductive technology.

Conclusion:

OSSPBT has a good prognosis. Its conventional ultrasound is characterized by irregular solid masses surrounding normal ovaries and a large number of “blizzard” signs. It showed low enhancement of eccentricity with irregular radial branches centered on the ovary by CEUS.

Progression of Cystadenoma to Mucinous Borderline Ovarian Tumor in Young Females: Case Series and Literature Review

STUDY OBJECTIVE

To study the progression of benign ovarian lesions to mucinous borderline ovarian tumors (mBOTs); analyze the clinicopathologic features, diagnosis, and management of mBOTs in pediatric and adolescent girls; and provide a review of the literature on mBOTs in this population.

DESIGN

Retrospective chart review of female adolescents younger than 18 years diagnosed with mBOTs between July 2017 and February 2021.

SETTING

Yale New Haven Hospital, New Haven, Connecticut; and Yale New Haven Health Bridgeport Hospital, Bridgeport, Connecticut.

PARTICIPANTS

Three female patients diagnosed with mBOTs between ages 12 and 17 years.

INTERVENTIONS

None.

MAIN OUTCOME MEASURES

Clinical presentation, preoperative characteristics, surgical technique, histology, tumor stage, treatment, progression, outcome, and rate of recurrence.

RESULTS

Three adolescent patients were identified to have mBOTs. All three patients presented with a chief complaint of abdominal pain. One of the 3 patients was premenarchal at presentation. Two of the 3 patients were initially diagnosed with a mucinous cystadenoma and had recurrences of an ovarian cyst in the same ovary within 5 and 17 months, respectively. Pathology of the recurrent cyst was consistent with mBOT. Two of the 3 patients initially underwent cystectomy, and all ultimately had a unilateral salpingo-oophorectomy. Subsequent surveillance over 2 to 4 years found no evidence of disease recurrence.

CONCLUSION

mBOTs are rare in the pediatric and adolescent population and could arise from benign ovarian tumors.

Fertility after Cancer: Risks and Successes

Simple Summary

Approximately one million new cases of cancer are diagnosed in women of reproductive age every year. In the last few decades, advances in early diagnosis and treatment have improved the survival rate. However, the adverse effects of anticancer therapy on the ovaries and uterus have a significant impact on future fertility and may affect the quality of life of cancer survivors. Unfortunately, evidence about the trend of ovarian reserve loss over time is insufficient for predicting the duration of the fertile period. Currently, impaired fertility in cancer survivors is a growing issue that is complicated by an increasing number of women delaying childbearing. This review focuses on the detrimental effects of chemotherapy, radiotherapy, and surgery on reproductive functions and describes the mechanisms causing reduced fertility in cancer survivors. Moreover, in this review, the available fertility preservation strategies to guarantee the chance of motherhood in cancer survivors are illustrated.

Abstract

The incidence of cancer in reproductive-aged women is 7%, but, despite the increased number of cancer cases, advances in early diagnosis and treatment have raised the survival rate. Furthermore, in the last four decades, there has been a rising trend of delaying childbearing. There has been an increasing number of couples referred to Reproductive Medicine Centers for infertility problems after one partner has been treated for cancer. In these cases, the main cause of reduced fertility derives from treatments. In this review, we describe the effects and the risks of chemotherapy, radiotherapy, and surgery in women with cancer, and we will focus on available fertility preservation techniques and their efficacy in terms of success in pregnancy and live birth rates.

Oncological and reproductive outcomes after fertility-sparing surgery in patients with seromucinous borderline ovarian tumor: Results of a large retrospective study

OBJECTIVE

To evaluate the oncological and reproductive outcomes in patients with seromucinous borderline ovarian tumors (SMBOT) treated with fertility-sparing surgery (FSS).

METHODS

We retrospectively reviewed the medical records of patients with SMBOT who underwent surgery between 2000 and 2019. A centralized histological review was performed and recurrence rates were compared between different surgical procedures.

RESULTS

A total of 105 patients fulfilled the inclusion criteria, of whom 65 underwent FSS and 40 were treated with radical surgery (RS). Fourteen patients had recurrent disease after a median follow-up time of 59.6 months (range: 22.1-256.8 months). All but one relapsed with SMBOT. There was no significant difference in disease-free survival (DFS) between the two groups (P = 0.141). Multivariate analysis showed that only bilateral involvement was associated with increased recurrence (P = 0.008). In the subgroup of patients treated with conservative surgery, there was no significant difference in DFS with regard to surgical procedures (ovarian cystectomy vs salpingo-oophorectomy, P = 0.487). Of the 12 patients in the FSS group who developed recurrence, 11 underwent a second round of FSS and all remained alive with no evidence of disease at the end of follow-up. Of 20 patients desiring pregnancy, 16 patients were successful and resulted in 17 term deliveries.

CONCLUSIONS

FSS is feasible for young patients who wish to preserve their fertility. Patients initially treated with ovarian cystectomy may be managed by close surveillance if post-operative imaging are negative. Repeat FSS remains a valuable alternative for young patients with recurrent SMBOT after thorough communication.

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

OBJECTIVE

Epithelial borderline ovarian tumor (BOT) frequently occurs in young women. Because progression-free survival, overall survival, and reproductive function are important outcomes, BOT is often treated by fertility-sparing surgery (FSS). We conducted a Japan-wide study to understand post-FSS prognosis in relation to clinical characteristics and types of FSS performed.

METHODS

We analyzed clinical and outcome data pertaining to 531 adolescent and young adult (AYA) patients (aged 15-39 years) who underwent FSS for BOT between 2009 and 2013.

RESULTS

Median (range) age was 30 (15-39) years, and median observation time was 70 (2-120) months. The disease was of FIGO stage I in 492 (93%) patients. Histopathologically, tumors were of the mucinous (n = 372, 70%), serous (n = 120, 23%), seromucinous (n = 23, 4%), and other (n = 16, 3%) types. Five-year overall survival was 99.5% among patients with stage I and 100% among those with stage II-IV. Five-year progression-free survival was 96.7% and 69.3%, respectively. Multivariate analysis in cases of stage I showed a positive peritoneal cytology to be a significant risk factor for recurrence (HR, 5.199; p = 0.0188). The post-FSS pregnancy rate was relatively low for patients aged ≥30 years (OR, 0.868; 95% CI, 1.16-3.00; p = 0.0090).

CONCLUSION

Post-FFS outcomes in terms of overall and progression-free survival are favorable, especially for AYA patients with stage I BOT. However, the relapse rate is high for patients with FIGO stage II-IV and for those with stage I but a positive peritoneal cytology. A long-term prospective observation is needed before reproductive outcomes can be fully established.

Fertility-Sparing Surgery for Ovarian Cancer

(1) Background: although most patients with epithelial ovarian cancer (EOC) undergo radical surgery, patients with early-stage disease, borderline ovarian tumor (BOT) or a non-epithelial tumor could be offered fertility-sparing surgery (FSS) depending on histologic subtypes and prognostic factors. (2) Methods: we conducted a systematic review to assess the safety and fertility outcomes of FSS in the treatment of ovarian cancer. We queried the MEDLINE, PubMed, Cochrane Library, and Cochrane (“Cochrane Reviews”) databases for articles published in English or French between 1985 and 15 January 2021. (3) Results: for patients with BOT, FSS should be offered to young women with a desire to conceive, even if peritoneal implants are discovered at the time of initial surgery. Women with mucinous BOT should undergo initial unilateral salpingo-oophorectomy, whereas cystectomy is an acceptable option for women with serous BOT. Assisted reproductive technology (ART) can be initiated in patients with stage I BOT if infertility persists after surgery. For patients with EOC, FSS should only be considered after staging for women with stage IA grade 1 (and probably 2, or low-grade in the current classification) serous, mucinous or endometrioid tumors. FSS could also be offered to patients with stage IC grade 1 (or low-grade) disease. For women with serous, mucinous or endometrioid high-grade stage IA or low-grade stage IC1 or IC2 EOC, bilateral salpingo-oophorectomy and uterine conservation could be offered to allow pregnancy by egg donation. Finally, FSS has a large role to play in patients with non- epithelial ovarian cancer, and particularly women with malignant ovarian germ cell tumors.

The complex relationship between infertility and female genital tract cancer: A review

INTRODUCTION

The link between female infertility and gynecological cancer has always been a debated and challenging topic. Although cervical cancer has the worst impact on female fertility, as it is usually diagnosed in patients of reproductive age, endometrial and ovarian cancer are also diagnosed and treated often in relatively younger patients in which fertility preservation is a relevant issue. The aim of this review is to highlight the correlation between therapy for female infertility and the developing cancer's risk and to describe the fertility sparing treatments in gynecological oncology.

MATERIAL AND METHODS

A systematic review of the literature through the main scientific search engines (PubMed and Google Scholar) was performed. We selected the most relevant articles based on the largest case series and the latest updates. All selected documents have been listed in the references.

RESULTS

Fifty-six relevant articles published between 1996 and 2019 were identified.Results from the available evidence report no significant increased risk of endometrial, cervical, and ovarian cancer in patients having infertility treatments.In young patients diagnosed with gynecological cancer, preservation of fertility is a personalized choice depending on several factors (type, stage, age and desire to conceive, safety of the treatment, and feasibility of fertility sparing surgery). For ovarian cancer FIGO stage IA G1, IA G2 (grade), and IC G1; for endometrial adenocarcinoma grade 1 with no lymphovascular space invasion (LVSI) or myometrial invasion and for early-stage cervical cancer (FIGO stage 2018: IA1-IB1), fertility sparing treatment is possible. The role of fertility sparing treatment with the increase of personalization of therapies therapy is always a theme of discussion and research.

CONCLUSION

At present data regarding the risk of gynecological cancers after infertility treatments are reassuring. Careful evaluation of female fertility-sparing options in young women interested by ovarian, endometrial, or cervical tumors should be carried out involving a multidisciplinary team and ensuring safety and efficacy.

Is cystectomy an option as conservative surgery for young patients with borderline ovarian tumor? A multi-institutional retrospective study

OBJECTIVE

To investigate the impact of cystectomy for borderline ovarian tumor (BOT) on tumor recurrence compared with salpingo-oophorectomy using inverse probability of treatment weighting (IPTW).

METHODS

A central pathologic review and a search of the medical records from 14 collaborating institutions from 1986 to 2017 identified 4708 women with a malignant ovarian neoplasm. Data for young women with Stage I BOT were extracted. To compare recurrence-free survival between the surgery groups, Cox regression analyses and the IPTW-adjusted Kaplan-Meier method were employed.

RESULTS

During a median follow-up of 62.0 (1.2-270.4) months, 10 of the 285 patients identified (3.5%) developed recurrence. In multivariate analysis, the practice of cystectomy was not a significant prognostic indicator of recurrence-free survival (hazard ratio [95% confidence interval] 1.276 [0.150-10.864]; P = 0.823). In the IPTW-adjusted cohort, the 5-year recurrence-free survival rates were 95.8% and 96.0% in patients receiving cystectomy and salpingo-oophorectomy, respectively (P = 0.378).

CONCLUSION

If patients are selected appropriately, cystectomy in itself may not increase tumor recurrence in young women with early-stage BOT. A large-scale prospective clinical study is necessary to validate this finding.

Oncofertility outcomes after fertility-sparing treatment of bilateral serous borderline ovarian tumors: results of a large retrospective study

STUDY QUESTION

What are the oncofertility outcomes of young women (≤40 years old) with bilateral serous borderline ovarian tumors (SBOTs) after fertility-sparing surgery?

SUMMARY ANSWER

Fertility preservation with the bilateral ovarian cystectomy procedure is feasible for bilateral SBOTs, with an acceptable oncological outcome and worthwhile pregnancy rates.

WHAT IS KNOWN ALREADY

Fertility-sparing approaches are becoming the standard management of young patients with unilateral SBOTs and other borderline histological subtypes. However, there is a paucity of evidence to dictate the best management in bilateral SBOTs.

STUDY DESIGN, SIZE, DURATION

This was a retrospective observational study performed at the Peking Union Medical College Hospital in Beijing, China, between January 1999 and January 2019.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Ninety-four women (≤40 years old) with pathologically confirmed bilateral SBOTs were included. Following preoperative counseling, patients self-selected into one of three treatment modalities: bilateral ovarian cystectomy (n = 48), unilateral adnexectomy plus contralateral cystectomy (UAC; n = 31), and radical surgery (n = 15). Univariate and multivariate analyses were used to determine the clinical and pathological features associated with disease-free survival and reproductive outcomes.

MAIN RESULTS AND THE ROLE OF CHANCE

During the median follow-up of 64 months (range, 4-243 months), 61 patients (65%) developed relapse, including 3 (20%) in the radical group, 26 (84%) in the UAC group and 32 (67%) in the bilateral cystectomy group. In the multivariate analyses, preoperative CA-125>300 U/mL, fertility preservation and micropapillary pattern were independently associated with adverse disease-free survival (P = 0.001, 0.03 and 0.026, respectively). Fourteen patients (15%) experienced invasive recurrence, and three (3%) died of progressive disease. The micropapillary pattern was significantly associated with invasive evolution risk (P = 0.006). Of the 49 patients who attempted to conceive, 23 (47%) achieved 27 pregnancies (24 spontaneous and three after IVF-ET), resulting in 19 live births. There was no significant difference in disease-free survival (P = 0.13) or pregnancy rate (41 vs. 50%, P = 0.56) between the UAC and bilateral procedures.

LIMITATIONS, REASONS FOR CAUTION

As a retrospective study conducted in a referral center, inherent biases exist. The nonrandom allocation to treatment groups and relatively small number of patients attempt to conceive might limit the statistical power of our findings. Only 41 patients (43.6%) received complete staging during their initial surgeries, so an underestimation bias in terms of the FIGO stage and extraovarian implants might have occurred.

WIDER IMPLICATIONS OF THE FINDINGS

The ultraconservative bilateral ovarian cystectomy procedure should be proposed in bilateral SBOTs when technically feasible. Invasive evolution occurs frequently in these women, and intense follow-up and oncofertility counseling are warranted, especially for those with micropapillary patterns.

STUDY FUNDING/COMPETING INTEREST(S)

No external funding was used for this study. There are no conflicts of interest to declare.

Fertility preservation in women with malignant and borderline ovarian tumors: Experience of the French ESGO-certified center and pregnancy-associated cancer network (CALG)

OBJECTIVE

To describe strategy and results of fertility preservation (FP) in patients with malignant and borderline ovarian tumors.

METHODS

Consecutive cohort study of 43 women with malignant or borderline ovarian tumors who underwent FP between February 2013 and July 2019. The study was conducted in national expert center in Tenon University Hospital, Sorbonne University: French ESGO-certified ovarian cancer center and pregnancy-associated cancer network (CALG). Main outcome measure was FP technique proposed by multidisciplinary committee, FP technique used, time after surgery, number of fragments, histology and follicle density (if ovarian tissue freezing), number of expected, retrieved and frozen oocytes (if ovarian stimulation).

RESULTS

Pathological diagnosis was malignant epithelial ovarian tumor in five women (11.6%), rare malignant ovarian tumor in 14 (32.6%), borderline in 24 (55.8%), and mostly unilateral (79.1%) and stage I (76.7%). Mean age at diagnosis was 26.8 ± 6.9 years and mean tumor size 109.7 ± 61 mm. Before FP, mean AFC was 11.0 ± 6.1 and AMH levels were 2.7 ± 4.6 ng/mL. Six ovarian tissue-freezing procedures were performed (offered to 13). Twenty-four procedures of ovarian stimulation and oocyte freezing were performed after surgical treatment for 19 women (offered to 28) with a median interval of 188 days. The mean number of mature oocytes retrieved per stimulation was 12.4 ± 12.8. At least 10 mature oocytes were frozen for 52.6% of the women. No FP was offered to five women.

CONCLUSION

Oocyte and ovarian tissue cryopreservation should be offered to patients with malignant and borderline ovarian tumors. More data are needed to confirm ovarian stimulation and ovarian tissue grafting safety.

Fertility-sparing treatment in advanced-stage serous borderline ovarian tumors. An analysis from the MITO14 study database

OBJECTIVES

To evaluate oncological and reproductive outcomes of women undergoing fertility-sparing surgery (FSS) for stage II-III serous borderline ovarian tumors (BOTs).

METHODS

A multi-institutional retrospective study was conducted within the MITO Group.

RESULTS

A total of 91 patients were recruited. The median follow-up time from primary cytoreduction was 127 months (IQR range 91-179). Forty-nine patients (53.8%) experienced at least one recurrence (median time to first relapse 22 months, IQR range 9.5-57). At univariable analysis, significant predictors of relapse were: size of largest extra-ovarian lesion, peritoneal cancer index, completeness of cytoreduction, type of implants. After multivariable analysis, the size of extra-ovarian lesions and the presence of invasive implants resulted as the only independent predictors of recurrence. Median disease-free survival (DFS) was 96 months (95% CI, 24.6-167.3), while median disease-specific survival (DSS) was not reached. Twenty-nine patients (31.8%) attempted to conceive: 20 (68.9%) achieved at least one pregnancy and 18 (62%) gave birth to a healthy child. At the end of the observation period, 88 patients (96.7%) showed no evidence of disease, 2 (2.2%) were alive with disease, and 1 patient (1.1%) died from BOT.

CONCLUSIONS

Despite the recurrence high rate, FSS provides good chances of reproductive success with no impact on DSS. The presence of invasive peritoneal implants affects the DFS but not DSS nor reproductive outcome. The risk of recurrence would not seem to be related to the ovarian preservation per se, but to the natural history of the initial peritoneal spread.

Outcomes after Fertility-sparing Surgery for Women with Ovarian Cancer: A Systematic Review of the Literature

OBJECTIVE

To compare reproductive and oncologic outcomes of patients diagnosed with early-stage epithelial ovarian carcinoma, borderline ovarian tumors, or nonepithelial ovarian carcinoma according to receipt of fertility-sparing surgery or conventional surgery.

DATA SOURCES

PubMed was searched from January 1, 1995, to May 29, 2020.

METHODS OF STUDY SELECTION

Studies were included if they (1) enrolled women of childbearing age diagnosed with ovarian cancer between the ages of 18 years and 50 years, (2) reported on oncologic and/or reproductive outcomes after fertility-sparing surgery for ovarian cancer, and (3) included at least 20 patients.

TABULATION, INTEGRATION, AND RESULTS

The initial search identified 995 studies. After duplicates were removed, we abstracted 980 unique citations. Of those screened, 167 publications were identified as potentially relevant, and evaluated for inclusion and exclusion criteria. The final review included 44 studies in epithelial ovarian cancer, 42 in borderline ovarian tumors, and 31 in nonepithelial ovarian carcinoma. The narrative synthesis demonstrated that overall survival does not seem to be compromised in patients undergoing fertility-sparing surgery compared with those undergoing conventional surgery, although long-term data are limited. Areas of controversy include safety of fertility-sparing surgery in the setting of high-risk factors (stage IC, grade 3, and clear cell histology), as well as type of surgery (salpingo-oophorectomy vs cystectomy). It seems that although there may be some fertility compromise after surgery, pregnancy and live-birth rates are encouraging.

CONCLUSION

Fertility-sparing surgery is safe and feasible in women with early-stage low-risk ovarian cancer. Pregnancy outcomes for these patients also seem to be similar to those of the general population.

Risk factors for recurrence of borderline ovarian tumors in France: A multicenter retrospective study by the FRANCOGYN group

INTRODUCTION

Borderline ovarian tumors (BOTs) although rare, have shown an increase in the incidence worldwide. Although the survival rate is high, the recurrence rate is estimated to be between 5% and 34%. The objective of this study was to identify risk factors for recurrence of BOTs.

METHODS

This retrospective multicenter study included 493 patients treated surgically for BOT between January 2001 and December 2018.

RESULTS

Thirty-seven patients showed recurrence (group R, 7.5%), while 456 did not (group NR, 92.5%). With an average follow-up of 30.5 months (1-276), the overall recurrence rate was 7.5%. Recurrence rates for the BOT and invasive types were 5.7% (n = 28) and 1.4% (n = 7), respectively. The mean time to recurrence was 44.1 (3-251) months. Univariate analysis showed that age at diagnosis, type of surgical procedure, histological type, and FIGO stage were factors influencing recurrence. Multivariate analysis showed that the risk factors for recurrence of BOT were conservative treatment (OR = 7 [95% CI 3.01-16.23]; p < 0.05) and advanced FIGO stage (OR = 5.86 [95% CI 2.21-15.5]; p < 0.05).

DISCUSSION

To the best of our knowledge, this multicenter study was one of the largest studies on the risk factors for BOT recurrence. Conservative treatment and advanced FIGO stage were identified as risk factors for BOT recurrence. These results reinforce the need for restaging of patients who did not have an optimal initial surgical staging so as not to avoid missing a tumor in the advanced stage. Referral to a surgical oncology center is suggested to optimize overall patient management.

Ultraconservative, Fertility Sparing Treatment of Bilateral Borderline Ovarian Tumors: A Case Report of a 26-Year-Old, 0-Gravida with an Endometrioid Borderline Ovarian Tumor of the Right Ovary and a Sero-Mucinous Borderline Ovarian Tumor of the Left Ovary and a Review of the Literature

Endometrioid borderline ovarian tumors are rare, entailing a lack of data on their natural history as well as the safety of conservative and ultraconservative surgical management, especially in cases with bilateral borderline ovarian tumors including one of endometrioid differentiation. Therefore, we present such a case and provide a review of the literature on endometrioid borderline ovarian tumors. We report the case of a 26-year-old, 0-gravida with an endometrioid borderline ovarian tumor of the right and a sero-mucinous borderline ovarian tumor of the left ovary treated by fertility sparing, ultraconservative surgery with bilateral cystectomy, completed by staging procedures including omentectomy and peritoneal sampling, as well as endometrial sampling by means of curettage. Reviewing the literature and taking into account the course of our case, we propose the feasibility of an ultraconservative management, including endometrial sampling, in young patients with bilateral borderline ovarian tumors including one of endometrioid differentiation who desire to preserve fertility, followed by a closely monitored follow-up.

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.

Borderline ovarian tumours: management in the era of fertility-sparing surgery

Borderline ovarian tumours (BOTs) are ovarian neoplasms characterised by epithelial proliferation, variable nuclear atypia and no evidence of destructive stromal invasion. BOTs account for approximately 15% of all epithelial ovarian cancers. Due to the fact that the majority of BOTs occur in women under 40 years of age, their surgical management often has to consider fertility-sparing approaches. The aim of this mini-review is to discuss the state of the art of fertility-sparing surgery for BOTs with a specific focus on the extent of surgery, post-operative management and fertility.

[Borderline Ovarian Tumours: CNGOF Guidelines for Clinical Practice - Fertility]

OBJECTIVES

Borderline ovarian tumours (BOT) represent around 15% of all ovarian neoplasms and are more likely to be diagnosed in women of reproductive age. Overall, given the epidemiological profile of BOT and their favourable prognosis, ovarian function and fertility preservation should be systematically considered in patients presenting these lesions.

METHODS

The research strategy was based on the following terms: borderline ovarian tumour, fertility, fertility preservation, infertility, fertility-sparing surgery, in vitro fertilization, ovarian stimulation, oocyte cryopreservation, using PubMed, in English and French.

RESULTS AND CONCLUSIONS

Fertility counselling should become an integral part of the clinical management of women with BOT. Patients with BOT should be informed that surgical management of BOT may cause damage ovarian reserve and/or peritoneal adhesions. Nomogram to predict recurrence, ovarian reserve markers and fertility explorations should be used to provide a clear and relevant information about the risk of infertility in patients with BOT. Fertility-sparing surgery should be considered for young women who wish preserving their fertility when possible. There is insufficient evidence to claim a causal relation between controlled ovarian stimulation (COS) and BOT. However, in case of poor prognosis factors, the use of COS should be considered cautiously through a multidisciplinary approach. In case of infertility after surgery for BOT, COS can be performed without delay, once histopathological diagnosis of BOT is confirmed. There is insufficient consistent evidence that fertility drugs and COS increase the risk of recurrence of BOT after conservative management. The conservative surgical treatment can be associated to oocyte cryopreservation considering the high risk of recurrence of the disease. In women with BOT recurrence in a single ovary and in women with bilateral ovarian involvement when the conservative management is not possible, other fertility preservation strategies are available, but still experimental.

[Borderline Ovarian Tumours: CNGOF Guidelines for Clinical Practice - Diagnosis and Management of Recurrent Borderline Ovarian Tumours]

OBJECTIVE

To provide recommendations for the diagnosis and management of the recurrence of Borderline Ovarian Tumour (BOT).

METHODS

Literature review by consulting Pubmed, Medline and Cochrane databases.

RESULTS

In the case of BOT, most of recurrences are a new BOT without invasive contingent (LE2). In the case of bilateral BOT, bilateral cystectomy is associated with a shorter recurrence time compared to unilateral oophorectomy and contralateral cystectomy (LE2). In recurrent serous BOT, cysts are usually fluid thin-walled with vegetation, corresponding in the IOTA classification to a solid unilocular cyst (LE2). A size of the cyst less than 20mm is not a sufficient to eliminate the diagnosis of recurrent serous BOT (LE2). Recurrence of mucinous BOT predominantly appears as multilocular or as solid multilocular cysts (LE4). In the case of ovarian preservation, recurrences are most often observed on the preserved ovary(s) (LE2). Non-invasive peritoneal recurrence after initial radical treatment including bilateral hysterectomy and adnexectomy is possible, mainly in patients initially diagnosed with stage II or III BOT with non-invasive peritoneal implant (LE3). Most BOT recurrences are asymptomatic, but clinical examination may allow diagnosis of recurrence (LE2). The normality of the CA 125 dosage does not rule out the diagnosis of recurrent BOT (LE2). A second conservative treatment in the event of recurrence of BOT entails the risk of new recurrence (LE2) with no impact on survival (LE4). Totalization of the adnexectomy in case of recurrence of BOT reduces the risk of new recurrence (LE2). Conservative treatment does not increase the risk of recurrence with non-invasive peritoneal implants (LE4). Conservative treatment may be offered after a first non-invasive recurrence in young women who wish to preserve their fertility (gradeC). In the absence of infiltrating tumor, chemotherapy is not indicated. The only cases for which chemotherapy can be considered are those for which there is an infiltrative component in addition to TFO.

[Borderline Ovarian Tumours: CNGOF Guidelines for Clinical Practice - Epidemiology and Risk Factors of Relapse, Follow-up and Interest of a Completion Surgery]

OBJECTIVE

To provide clinical practice guidelines from the French college of obstetrics and gynecology (CNGOF) based on the best evidence available, concerning epidemiology of recurrence, the risk or relapse and the follow-up in case of borderline ovarian tumor after primary management, and evaluation of completion surgery after fertility sparing surgery.

MATERIAL AND METHODS

English and French review of literature from 2000 to 2019 based on publications from PubMed, Medline, Cochrane, with keywords borderline ovarian tumor, low malignant potential, recurrence, relapse, follow-up, completion surgery. From 2000 up to this day, 448 references have been found, from which only 175 were screened for this work.

RESULTS AND CONCLUSION

Overall risk of recurrence with Borderline Ovarian Tumour (BOT) may vary from 2 to 24% with a 10-years overall survival>94% and risk of invasive recurrence between 0.5 to 3.8%. Age<40 years (level of evidence 3), advanced initial FIGO stage (LE3), fertility sparing surgery (LE2), residual disease after initial surgery for serous BOT (LE2), implants (invasive or not) (LE2) are risk factors of recurrence. In case of conservative treatment, serous BOT had a higher risk of relapse than mucinous BOT (LE2). Lymphatic involvement (LE3) and use of mini invasive surgery (LE2) are not associated with a higher risk of recurrence. Scores or Nomograms could be useful to assess the risk of recurrence and then to inform patients about this risk (gradeC). In case of serous BOT, completion surgery is not recommended, after conservative treatment and fulfillment of parental project (grade B). It isn't possible to suggest a recommendation about completion surgery for mucinous BOT. There is not any data to advise a frequency of follow-up and use of paraclinic tools in general case of BOT. Follow-up of treated BOT must be achieved beyond 5 years (grade B). A systematic clinical examination is recommended during follow-up (grade B), after treatment of BOT. In case of elevation of CA-125 at diagnosis use of CA-125 serum level is recommended during follow-up of treated BOT (grade B). When a conservative treatment (preservation of ovarian pieces and uterus) of BOT is performed, endovaginal and transabdominal ultrasonography is recommended during follow-up (grade B). There isn't any sufficient data to advise a frequency of these examinations (clinical examination, ultrasound and CA-125) in case of treated BOT.

CONCLUSION

Risk of relapse after surgical treatment of BOT depends on patients' characteristics, type of BOT (histological features) and modalities of initial treatment. Scores and nomogram are useful tools to assess risk of relapse. Follow-up must be performed beyond 5 years and in case of peculiar situations, use of paraclinic evaluations is recommended.

[Borderline Ovarian Tumours: CNGOF Guidelines for Clinical Practice - Therapeutic Management of Early Stages]

OBJECTIVES

To provide guidelines for clinical practice from the French College of Obstetrics and Gynecology (CNGOF), based on the best evidence available, concerning early stage borderline ovarian tumors (BOT).

METHODS

Bibliographical search in French and English languages by consultation of Pubmed, Cochrane, Embase, and international databases.

RESULTS

Considering management of early stage BOT, if surgery is possible without a risk of tumor rupture, the laparoscopic approach is recommended compared to laparotomy (Grade C). In BOT, it is recommended to take all the measures to avoid tumor rupture, including the peroperative decision of laparoconversion (Grade C). In BOT, extraction of the surgical specimen using an endoscopic bag is recommended (Grade C). In case of early stage, uni or bilateral BOT, suspected in preoperative imaging in a postmenopausal patient, bilateral adnexectomy is recommended (Grade B). In cases of bilateral BOT and desire of fertility preservation, a bilateral cystectomy is recommended (Grade B). In case of mucinous BOT and desire of fertility preservation, it is recommended to perform a unilateral adnexectomy (Grade C). In case of endometrioid BOT and desire of fertility preservation, it is not possible to establish a recommendation of treatment choice between cystectomy and unilateral adnexectomy. In case of mucinous BOT at definitive histological analysis in a woman of childbearing age who had an initial cystectomy, surgical revision for unilateral adnexectomy is recommended (Grade C). In the case of serous BOT with definitive histological analysis in a woman of childbearing age who has had an initial cystectomy, it is not recommended to repeat surgery for adnexectomy in the absence of residual suspicious lesion during initial surgery and/or on postoperative imaging (referent ultrasound or pelvic MRI) (Grade C). An omentectomy is recommended for complete initial surgical staging when BOT is diagnosed on extemporaneous analysis or suspected on preoperative radiological elements (Grade B). There is no data in the literature to recommend the type of omentectomy to be performed. If restaging surgery is decided for a presumed early stage BOT, an omentectomy is recommended (Grade B). Multiple peritoneal biopsies are recommended for complete initial surgical staging when BOT is diagnosed on extemporaneous or suspected on preoperative radiological elements (Grade C). In case of restaging surgery for a presumed early stage BOT, exploration of the abdominal cavity should be complete and peritoneal biopsies should be performed on suspicious areas or systematically (Grade C). A primary peritoneal cytology is recommended in order to achieve complete initial surgical staging when BOT is suspected on preoperative radiological elements (Grade C). In case of restaging surgery for presumed early stage BOT, a first peritoneal cytology is recommended (Grade C). For early serous or mucinous BOT, it is not recommended to perform a systematic hysterectomy (Grade C). For early stage endometrioid BOT, and in the absence of a desire to maintain fertility, hysterectomy is recommended for initial surgery or if restaging surgery is indicated (Grade C). For endometrioid-type early stage BOT, if there is a desire for fertility preservation, the uterus may be retained subject to good evaluation of the endometrium by imaging and endometrial sampling (Grade C). In case of surgery (initial or restaging if indicated) for early stage BOT, it is recommended to evaluate the macroscopic appearance of the appendix (Grade B). In case of surgery (initial or restaging if indicated) for early stage BOT, appendectomy is recommended only in case of macroscopically pathological appearance of the appendix (Grade C). Pelvic and lumbar aortic lymphadenectomy is not recommended for initial surgery or restaging surgery for early stage BOT regardless of histologic type (Grade C). In case of BOT diagnosed on definitive histology, the indication of restaging surgery should be discussed in Multidisciplinary Collaborative Meeting. For presumed early stage BOT, it is recommended to use the laparoscopic approach to perform restaging surgery (Grade C). Restaging surgery is recommended for serous BOT with micropapillary appearance and unsatisfactory abdominal cavity inspection during initial surgery (Grade C). Restaging surgery is recommended in case of mucinous BOT if only a cystectomy has been performed or the appendix has not been visualized, then a unilateral adnexectomy will be performed (Grade C). If a restaging surgery is decided in the management of a presumed early stage BOT, the actions to be carried out are as follows: a peritoneal cytology (Grade C), an omentectomy (there is no data in the literature recommending the type of omentectomy to be performed) (Grade B), a complete exploration of the abdominal cavity with peritoneal biopsies on suspect areas or systematically (Grade C), visualization of the appendix± the appendectomy in case of pathological macroscopic appearance (Grade C), unilateral adnexectomy in case of mucinous TFO (Grade C).

Fertility preservation in gynecologic cancers

An increasing number of women in modern societies are delaying childbearing beyond the age of 35, and gynecologic cancers affect a significant proportion of reproductive age women who wish to preserve fertility for a future chance of childbearing. As a result, providing treatment options for fertility preservation in women with gynecologic cancer has become a crucial component of cancer survivorship care. In this review article, we discussed the current knowledge on fertility-sparing surgical approaches, as well as assisted reproductive technologies that can be utilized to preserve reproductive potential in women with cervical, endometrial, and ovarian cancer. A brief section on fertility preservation in pediatric gynecologic malignancies is also provided.

Borderline Ovarian Tumors: Fifteen Years' Experience at a Scottish Tertiary Cancer Center

OBJECTIVES

Since the recognition of borderline ovarian tumors (BOTs) in the 1970s, the management of this subset of epithelial ovarian tumors has presented a challenge to clinicians. The majority present at an early stage, but their diagnosis is often only made following surgery, hence the heterogeneity of surgical management. Borderline ovarian tumors are morphologically diverse, and their behavior is subsequently also heterogeneous. We aimed to assess recurrence rates and the rate of malignant transformation in patients diagnosed with BOT. Secondary objectives included a review of current management and assessment of tumor markers, stage, cyst dimensions, and the presence of micropapillary features as prognostic indicators of recurrence.

METHODS

This retrospective cohort study included all patients treated with BOT between 2000 and 2015 in the southeast region of Scotland. Clinical, surgicopathological, and follow-up data were collated. Data were analyzed with reference to recurrence and malignant transformation.

RESULTS

Two hundred seventy-five patients underwent treatment for BOT in the study period. Surgical management was highly variable. A diagnosis of recurrent/persistent BOT or ovarian malignancy following initial treatment of BOT was rare, with only 12 (4%) of 275 cases. There were 7 cases (3%) of ovarian malignancy. Advanced International Federation of Gynecology and Obstetrics stage was the most prominent prognostic factor. Elevated preoperative serum CA-125 and the presence of micropapillary features correlated with advanced stage at presentation. With a lack of clear guidance, follow-up was highly variable with a median of 43 months (0-136 months).

CONCLUSIONS

To our knowledge, this study is the largest BOT cohort in the United Kingdom. Recurrent disease is rare in optimally staged, completely resected, early-stage BOT, without high-risk features. Caution is needed in women electing not to undergo completion staging after diagnosis and in those opting for a fertility-preserving approach. Thorough informed consent and clear plans for surveillance and follow-up are needed with consideration of delayed completion surgery as appropriate.

ESMO-ESGO consensus conference recommendations on ovarian cancer: pathology and molecular biology, early and advanced stages, borderline tumours and recurrent disease

The development of guidelines is one of the core activities of the European Society for Medical Oncology (ESMO) and European Society of Gynaecologial Oncology (ESGO), as part of the mission of both societies to improve the quality of care for patients with cancer across Europe. ESMO and ESGO jointly developed clinically relevant and evidence-based recommendations in several selected areas in order to improve the quality of care for women with ovarian cancer. The ESMO-ESGO consensus conference on ovarian cancer was held on April 12-14, 2018 in Milan, Italy, and comprised a multidisciplinary panel of 40 leading experts in the management of ovarian cancer. Before the conference, the expert panel worked on five clinically relevant questions regarding ovarian cancer relating to each of the following four areas: pathology and molecular biology, early-stage and borderline tumours, advanced stage disease and recurrent disease. Relevant scientific literature, as identified using a systematic search, was reviewed in advance. During the consensus conference, the panel developed recommendations for each specific question and a consensus was reached. The recommendations presented here are thus based on the best available evidence and expert agreement. This article presents the recommendations of this ESMO-ESGO consensus conference, together with a summary of evidence supporting each recommendation.

Ovarian masses in the child and adolescent: An American Pediatric Surgical Association Outcomes and Evidence-Based Practice Committee systematic review

BACKGROUND

The treatment of ovarian masses in pediatric patients should balance appropriate surgical management with the preservation of future reproductive capability. Preoperative estimation of malignant potential is essential to planning an optimal surgical strategy.

METHODS

The American Pediatric Surgical Association Outcomes and Evidence-Based Practice Committee drafted three consensus-based questions regarding the evaluation and treatment of ovarian masses in pediatric patients. A search of PubMed, the Cochrane Library, and Web of Science was performed and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed to identify articles for review.

RESULTS

Preoperative tumor markers, ultrasound malignancy indices, and the presence or absence of the ovarian crescent sign on imaging can help estimate malignant potential prior to surgical resection. Frozen section also plays a role in operative strategy. Surgical staging is useful for directing chemotherapy and for prognostication. Both unilateral oophorectomy and cystectomy have been used successfully for germ cell and borderline ovarian tumors, although cystectomy may be associated with higher rates of local recurrence.

CONCLUSIONS

Malignant potential of ovarian masses can be estimated preoperatively, and fertility-sparing techniques may be appropriate depending on the type of tumor. This review provides recommendations based on a critical evaluation of recent literature.

TYPE OF STUDY

Systematic review of level 1-4 studies.

LEVEL OF EVIDENCE

Safety and fertility outcomes after the conservative treatment of endometrioid borderline ovarian tumours

Background

Because of the rarity of endometrioid borderline ovarian tumours (EBOTs), there is a paucity of data concerning the natural history and prognosis of this condition. Thus, the objective of our study was to establish the feasibility of fertility preservation in young women with EBOTs, as well as their oncological and reproductive outcomes.

Methods

Consecutive patients with EBOTs, treated at a tertiary referral centre during a span of 22 years, were retrospectively analysed. Recurrence-free interval, as well as its association with the type of surgery and with other clinical and pathological features, was assessed using the Kaplan-Meier and Cox proportional hazards methods.

Results

Of the 59 patients studied, the median follow-up time was 30 months (range, 6–177 months). Nine (15.3%) patients developed 13 recurrences 6–137 months after the initial surgeries, including three patients (5.1%; n = 3/59) who developed six invasive recurrences 8, 18 and 68 months after their initial surgeries. Conservative surgery showed a tendency towards a high recurrence rate (17.2% versus 13.3%); however, this difference was not significant (p = 0.45). The 5-year recurrence-free survival rate was significantly higher in the oophorectomy group than in the cystectomy group (p = 0.001). Cox regression analysis showed that none of the variables assessed were associated with an increased hazard ratio for recurrence, except for a younger age at diagnosis (p = 0.021). Of 20 patients who attempted to conceive, three pregnancies among two patients (10.0%) resulted in two live births.

Conclusions

Conservative surgery with unilateral adnexectomy can be proposed for young women with EBOTs with fertility desire; however, the reproductive result is not satisfactory. In addition, careful evaluations of the endometria should be offered during the initial surgery and follow-up period.

Trial registration

Retrospectively registered.

The impact of clinicopathologic and surgical factors on relapse and pregnancy in young patients (≤40 years old) with borderline ovarian tumors

BACKGROUND

Fertility sparing surgery has been extensively performed among patients with borderline ovarian tumors due to their age and favorable prognosis. Nevertheless, the prognosis and obstetric outcomes in these patients remain uncertain. Thus, the current study was carried out to evaluate the oncological safety and fertility benefits of different fertility sparing surgery subtypes and various clinicopathological parameters.

METHODS

Young borderline ovarian tumor patients with an age of ≤40 years, who were admitted and treated in Zhejiang Cancer Hospital from January 1996 to December 2016, were enrolled in this study and reviewed retrospectively. The prognostic and obstetric effects of clinicopathological and surgical variables were evaluated using univariate/multivariate analyses and survival curves.

RESULTS

A total of 92 eligible patients were enrolled in the analysis. Among these patients, 22 (24%) patients showed recurrence after a median follow-up of 46.5 months. Within the fertility sparing surgery group, patients at advanced stage (≥stage II), of serous type, with micropapillary and bilateral tumors were associated with a higher recurrence rate and a shorter recurrence interval. In terms of different modalities of fertility sparing surgery, adnexectomy was remarkably favored over cystectomy-including (P = 0.012); unilateral salpingo-oophorectomy had better prognosis than cystectomy and bilateral cystectomy was favored over unilateral salpingo-oophorectomy+contralateral cystectomy. Univariate Cox regression analysis indicated that the International Federation of Gynecology and Obstetrics stage (≥Stage II), the presence of bilateral and micropapillary lesions, and the application of cystectomy-including surgery were correlated with poorer disease-free survival, while the mucinous type of borderline ovarian tumors was related to improved disease-free survival. In this study, a total of 22 patients attempted to conceive and 15 (68%) of these patients achieved successful pregnancy.

CONCLUSIONS

Unilateral salpingo-oophorectomy and bilateral cystectomy should be recommended as the preferred choice of treatment for young patients with unilateral and bilateral borderline ovarian tumor who desire to preserve fertility. In addition, borderline ovarian tumor patients at advanced stage (≥stage II), of serous type, with micropapillary and bilateral tumors should pay more attention to the risk of recurrence. Therefore, these patients should choose fertility sparing surgery carefully and attempt to achieve pregnancy as soon as possible.

Surgical approach to giant ovarian masses in adolescents: technical considerations

Ovarian neoplasms arising from the surface epithelium are rare in the pediatric population; their knowledge is therefore limited and the appropriate management is poorly defined. We describe our experience and suggest our surgical approach to adolescents affected by voluminous ovarian masses. Two 15-year-old adolescents were admitted to our institution in 2017 for multilobulated, fluid-filled masses measuring over 30 cm arising from the ovaries. The cystic component was drained intraoperatively with a spillage-free technique, consisting in the application of a sterile autoadhesive transparent drape on the cyst and the insertion of a 12 Ch pleural drain, secured with a purse-string suture. Unilateral salpingo-oophorectomy was then carried out. Histology revealed mucinous cystadenoma in both patients. Surgical treatment of ovarian masses should aim at both radically excising the tumor and preserving the fertility of the patients. Decompression with spillage-free techniques can be useful to achieve radical therapy with limited manipulation of tissues.

Risk of synchronous endometrial disorders in women with endometrioid borderline tumors of the ovary

Background

Synchronous endometrial disorders have been poorly studied in women with endometrioid borderline ovarian tumors (EBOT). The aims of this study were to investigate the risk of endometrial disorders among women with EBOT and associated factors, as well as their oncological and fertility outcomes.

Results

This retrospective study included 33 women with EBOT. Their mean age was 41.9 years, and endometria were evaluated in 25 of these patients. The prevalence of synchronous endometrial disorders was 52.0% (n = 13/25) and this incidence was 41.4% (n = 46/111) after systematic analysis. Univariable analysis showed that EBOT patients who were younger, nulliparous, and had experienced abnormal vaginal bleeding were more likely to have synchronous endometrial disorders. The median follow-up was 54 months (range: 14-250 months), and three patients (10.3%) developed recurrences. No deaths due to EBOT were recorded. Among the nine nulliparous women treated conservatively who were attempting to conceive, only one (11.1%) pregnancy resulted in a live birth.

Conclusions

Synchronous endometrial disorders are common in women with EBOT, especially in those who are younger, nulliparous, and have experienced abnormal vaginal bleeding. Thus, endometrial sampling should be performed in women with EBOT undergoing conservative surgery, and a hysterectomy should be performed in cases requiring radical treatment.

Borderline Ovarian Tumor in the Pediatric and Adolescent Population: A Case Series and Literature Review

STUDY OBJECTIVE

To determine the diagnosis, management, and outcome for children and adolescents with borderline ovarian tumor (BOT), and to provide a review of the literature on BOT in children and adolescents.

DESIGN

A retrospective cohort study of female adolescents younger than age 21 years diagnosed with BOT between January 2001 and May 2016.

SETTING

Texas Children's Hospital, Houston, Texas.

PARTICIPANTS

Fourteen patients (ages 12 to 18 years) diagnosed with BOT.

MAIN OUTCOME MEASURES

Clinical presentation, preoperative characteristics, surgical technique, cancer stage, histology, treatment, and recurrence.

RESULTS

Median age at diagnosis was 15.5 years, with most postmenarchal. Abdominal mass/pain were the most common presenting symptoms. Median tumor size was 16.6 cm (range, 4-32 cm). Preoperative cancer antigen 125 (CA 125) was elevated in 54% (7/13) of cases. All patients had fertility-preserving surgery, either cystectomy (CY) or unilateral salpingo-oophorectomy (USO): 5 via laparoscopy (LSC) and 9 via laparotomy. Most were stage I with 5 serous and 9 mucinous BOT histology. No one received adjuvant chemotherapy. Two patients had recurrence. One had ipsilateral recurrence 2 months after LSC CY for FIGO stage IC1 mucinous BOT. The second had contralateral recurrence 15 months after laparotomy, right USO for FIGO stage IIIC serous BOT treated with LSC CY, then a second recurrence treated with USO after oocyte cryopreservation for fertility preservation. All patients were alive at last follow-up, 1 with disease.

CONCLUSIONS

BOT in children and adolescents can be treated conservatively with fertility-preserving techniques and surveillance with good outcome. The role of adjuvant therapy is not known.

Fertility-sparing for young patients with gynecologic cancer: How MRI can guide patient selection prior to conservative management

Historically, cancer treatment has emphasized measures for the "cure" regardless of the long-term consequences. Advances in cancer detection and treatment have resulted in improved outcomes bringing to the fore various quality of life considerations including future fertility. For many young cancer patients, fertility preservation is now an integral component of clinical decision-making and treatment design. Optimal fertility-sparing options for young patients with gynecologic cancer are influenced by patient age, primary cancer, treatment regimens, and patient preferences. Possible approaches include embryo or oocyte cryopreservation, ovarian transposition, conservative surgery, and conservative medical treatment to delay radical surgery. These may be used alone or in combination to maximize fertility preservation. Awareness of the various fertility-sparing options, eligibility criteria, and the central role of magnetic resonance imaging in the proper selection of patients will enable radiologists to produce complete clinically relevant imaging reports and serve as effective consultants to referring clinicians. Knowledge of the potential imaging pitfalls is essential to avoid misinterpretation and guide appropriate management.

Fertility preservation in women with borderline ovarian tumors - how does it impact disease outcome? A cohort study

INTRODUCTION

Borderline ovarian tumors are typically indolent neoplasms. Since many are diagnosed in younger women, fertility conservation is an important consideration and has been advocated based on retrospective data. The objective of this study was to identify features impacting on recurrence and survival in a series of borderline ovarian tumors, and to assess the safety of a fertility-sparing approach.

MATERIAL AND METHODS

A historical cohort study of consecutive borderline ovarian tumors cases treated at a single institution over 30 years (1981-2011). Data on surgical approach (fertility-sparing or otherwise), disease stage, CA125 levels, histological features, adjuvant treatment and follow-up data were collected. Recurrence and survival were assessed using the Kaplan-Meier method and associations with the variables of interest were evaluated using a multivariate Cox proportional hazards model.

RESULTS

213 patients were included. Of 132 women age 40 years and below at diagnosis, 112 (85%) had a fertility-sparing procedure and 60 (46%) had conservation of an involved ovary. Fifty patients (24%) developed recurrences; fertility preservation (hazard ratio = 2.57; 95% confidence interval 1.1-6; p = 0.029) and advanced stage (hazard ratio = 4.15; 95% confidence interval 2.3-7.6; p < 0.001) were independently associated with recurrence on multivariate analysis. Eleven (5%) patients died of their disease. Fertility preservation was not associated with compromised survival.

CONCLUSIONS

Borderline ovarian tumors carry a good prognosis overall. Fertility preservation is associated with a higher risk of disease relapse; however, as most relapses are localized and may be salvaged with surgical treatment, overall survival is not compromised.

Laparoscopy versus laparotomy for FIGO stage I ovarian cancer

BACKGROUND

This is an updated version of the original review that was first published in the Cochrane Database of Systematic Reviews 2008, Issue 4. Laparoscopy has become an increasingly common approach to surgical staging of apparent early-stage ovarian tumours. This review was undertaken to assess the available evidence on the benefits and risks of laparoscopy compared with laparotomy for the management of International Federation of Gynaecology and Obstetrics (FIGO) stage I ovarian cancer.

OBJECTIVES

To evaluate the benefits and harms of laparoscopy in the surgical treatment of FIGO stage I ovarian cancer (stages Ia, Ib and Ic) when compared with laparotomy.

SEARCH METHODS

For the original review, we searched the Cochrane Gynaecological Cancer Group Trials (CGCRG) Register, Cochrane Central Register of Controlled Trials (CENTRAL 2007, Issue 2), MEDLINE, Embase, LILACS, Biological Abstracts and CancerLit from 1 January 1990 to 30 November 2007. We also handsearched relevant journals, reference lists of identified studies and conference abstracts. For the first updated review, the search was extended to the CGCRG Specialised Register, CENTRAL, MEDLINE, Embase and LILACS to 6 December 2011. For this update we searched CENTRAL, MEDLINE, and Embase from November 2011 to September 2016.

SELECTION CRITERIA

Randomised controlled trials (RCTs), quasi-RCTs and prospective cohort studies comparing laparoscopic staging with open surgery (laparotomy) in women with stage I ovarian cancer according to FIGO.

DATA COLLECTION AND ANALYSIS

There were no studies to include, therefore we tabulated data from non-randomised studies (NRS) for discussion as well as important data from other meta-analyses.

MAIN RESULTS

We performed no meta-analyses.

AUTHORS' CONCLUSIONS

This review has found no good-quality evidence to help quantify the risks and benefits of laparoscopy for the management of early-stage ovarian cancer as routine clinical practice.

Fertility Risk Assessment and Preservation in Male and Female Prepubertal and Adolescent Cancer Patients

Cancer represents the second cause of death in prepubertal children and adolescents, although it is currently associated with an overall survival rate of 80%–85%. The annual incidence rate is 186.6 per 1 million children and adolescents aged up to 19 years. Both disease and treatment options are associated with life-altering, long-term effects that require monitoring. Infertility is a common issue, and as such, fertility preservation represents an essential part in the management of young patients with cancer who are at risk of premature gonadal failure. This review deals with the up-to-date available data on fertility risk assessment and preservation strategies that should be addressed prior to antineoplastic therapy in this vulnerable subgroup of cancer patients.
