Fertility preservation in ovarian tumours

Clinical Challenges in the Management of Malignant Ovarian Germ Cell Tumours

Nonepithelial ovarian cancers (NEOC) are a group of rare malignancies, including germ cell tumours (GCT) and sex cord-stromal tumours (SCST), along with small-cell carcinomas and sarcomas. GCTs represent 2-5% of ovarian cancers, with a yearly incidence of 4:100,000, and they usually affect young women and adolescents. Precursory germ cells of the ovary form the basis of GCT. They are histologically classified into primitive GCT, teratomas, and monodermal and somatic-type tumours associated with dermoid cysts. A primitive GCT can be either a yolk sac tumour (YST), dysgerminoma, or mixed germ cell neoplasm. Teratomas are either mature (benign) or immature (malignant). Given that malignant GCTs occur rarely compared to epithelial ovarian tumours (EOC), greater focus is required in their diagnosis and treatment. In this article, we review the epidemiology, clinical manifestations, diagnosis, and molecular biology, along with the management and therapeutic challenges.

Lipid Alterations in Early-Stage High-Grade Serous Ovarian Cancer

Epithelial ovarian cancer (OC) ranks first in the number of deaths among diseases of the female reproductive organs. Identification of OC at early stages is highly beneficial for the treatment but is highly challenging due to the asymptomatic or low-symptom disease development. In this study, lipid extracts of venous blood samples from 41 female volunteers, including 28 therapy-naive patients with histologically verified high-grade serous ovarian cancer at different stages (5 patients with I-II stages; 23 patients with III-IV stages) and 13 apparently healthy women of reproductive age, were profiled by high-performance liquid chromatography mass spectrometry (HPLC-MS). Based on MS signals of 128 differential lipid species with statistically significant level variation between the OC patients and control group, an OPLS-DA model was developed for the recognition of OC with 100% sensitivity and specificity R2 = 0.87 and Q2 = 0.80. The second OPLS-DA model was developed for the differentiation between I-II OC stages and control group with R2 = 0.97 and Q2 = 0.86 based on the signal levels of 108 differential lipid species. The third OPLS-DA model was developed for the differentiation between I-II OC stages and III-IV stages based on the signal levels of 99 differential lipid species. Various lipid classes (diglycerides, triglycerides, phosphatidylchlorines, ethanolamines, sphingomyelins, ceramides, phosphatidylcholines and phosphoinositols) in blood plasma samples display distinctly characteristic profiles in I-II OC, which indicates the possibility of their use as marker oncolipids in diagnostic molecular panels of early OC stages. Our results suggest that lipid profiling by HPLC-MS can improve identification of early-stage OC and thus increase the efficiency of treatment.

Incidental finding of an ovarian epithelial tumor, adequate approach and fertility preservation: A case report

Introduction. Ovarian carcinoma is the fifth leading cause of death in women. In 3?14% of cases, it occurs in women under the age of 40 who intend to have children. Studies have shown a high survival rate if the tumor is diagnosed and treated at an early stage, with a 5-year survival rate of 91.2%, which makes a conservative treatment a valid option. Preserving fertility is safe for grade 1 and 2 of the International Federation of Gynecology and Obstetrics (FIGO) stage I epithelial ovarian carcinomas. A sparing operation involves salpingoophorectomy on the tumor side, multiple biopsies of suspected sites, blind biopsies and infracolic omentectomy, as well as cytological analysis of the wash. Case report. A 25-year-old patient, G0, P0, went to the gynecologist due to severe pain in the lesser pelvis. An ultrasound examination revealed a cystic hypoechoic alteration in the right ovary of about 5 ? 6 cm, suspected for torsion, and the patient was urgently operated. A right cystectomy was performed. The histopathological finding of the surgically removed cyst was: endometrioid adenocarcinoma of the ovary, histological grade 2 (HG2) and nuclear grade 2 (NG2), without lymphovascular invasion and no penetration of the capsule, submitted in parts. As the surgery performed did not reveal the degree of ovarian malignant tumor spreading, the FIGO stage could not be determined, and a second operation was necessary to stage the disease according to the FIGO protocol for ovarian cancer. Conclusion. Fertility preservation in patients with malignant ovarian epithelial tumors is a major challenge. The intense desire of the patient to have children has to be satisfied without reducing the success of treatment for this type of disease. The staging of the disease spreading is of paramount importance in order to make an adequate decision regarding the treatment.

Reproductive issues in carriers of germline pathogenic variants in the BRCA1/2 genes: an expert meeting

BACKGROUND

Healthy individuals and patients with cancer who are carriers of germline pathogenic variants in the BRCA1/2 genes face multiple reproductive challenges that require appropriate counseling and specific expertise.

MAIN BODY

On December 5th-7th, 2019, patient advocates and physicians with expertise in the field of reproductive medicine, fertility preservation, and oncology were invited to "San Giuseppe Moscati" Hospital in Avellino (Italy) for a workshop on reproductive management of women with germline pathogenic variants in the BRCA1/2 genes. From the discussion regarding the current evidence and future prospective in the field, eight main research questions were formulated and eight recommendations were developed regarding fertility, fertility preservation, preimplantation genetic testing, and pregnancy in healthy carriers and patients with cancer.

CONCLUSION

Several misconceptions about the topic persist among health care providers and patients often resulting in a discontinuous and suboptimal management. With the aim to offer patient-tailored counseling about reproductive issues, both awareness of current evidences and research should be promoted.

Ovarian Sertoli-Leydig cell tumours: A systematic review of relapsed cases

OBJECTIVE

To synthesize the evidence on Sertoli-Leydig cell tumour (SLCT) relapses, and identify the clinicopathological characteristics and prognosis of patients with recurrent SLCT.

METHODS

A literature search was undertaken of all published cases of SLCT relapse found in PubMed, Embase and Web of Science databases between January 1998 and January 2021. All articles in English reporting at least one case of SLCT relapse and mentioning the relapse location or the follow-up data were included. All reported data on relapsed cases were extracted. Student's t-test and Chi-squared test were used for the descriptive analysis, and the Kaplan-Meier statistical method was applied for survival analysis.

RESULTS

Eighty-five patients from 33 articles were included in this review. The median age was 20 years (range 3-76 years) with a median time to relapse of 14 months (range 1-168 months). Forty-eight percent (36/75) of relapses were local and 52% (39/75) were distant. In the subgroup of conservative primary surgery, contralateral ovarian SLCT events (metachronous or recurrent) were more frequent in the paediatric population than in the adult population (58.3 vs 18.2%; p = 0.005). Eleven cases had multiple relapses. Twenty-one percent (12/57) of cases were treated with conservative surgery after recurrence, and 64.9% (37/57) of cases were treated with radical surgery which tends to have a better 2-year survival rate (78.5% vs 61.0%; p = 0.177). Overall median survival was 48 months after recurrence (95% confidence interval ±21.0 months) with overall 5-year survival of 38.9%. The mean survival time was significantly higher for patients diagnosed at an early stage (I and II) compared with patients diagnosed at an advanced stage (p = 0.003).

DISCUSSION

The results showed that SLCT relapses have a poor prognosis and occur mainly in young patients, soon after the initial diagnosis. The majority of SLCT relapses are located in the abdominopelvic region. Contralateral ovarian SLCT events (metachronous or recurrent) occurred more frequently in paediatric cases. Multi-modal treatment with surgery and chemotherapy appears to be the best approach. The best chemotherapeutic regimen has yet to be defined.

Update on surgical treatment of female stress urinary incontinence

INTRODUCTION

Urinary incontinence is a common condition that negatively impacts quality of life of millions of women. It is a result of a synergy between the structures of pelvic floor in particular levator ani muscle and pelvic connective tissues. Urinary incontinence, increasing with age, is associated with considerable personal and societal expenditure.

EVIDENCE ACQUISITION

Systematic data search performed using PubMed/Medline database up to August 20, 2020. Focus was only for English language publications of original studies on urinary incontinence and in particular stress urinary incontinence.

EVIDENCE SYNTHESIS

Given the basis of published evidence and the consensus of European experts, this study provides an updated overview on clinical applications and surgical procedures of urinary incontinence.

CONCLUSIONS

Urinary incontinence is an underestimated health problem. Many surgical options exist for women with stress urinary incontinence. Nevertheless, new strategies need to be evaluated in order to improve quality of life of patients.

Fertility preservation in women with early ovarian cancer

Fertility preservation is an important option to consider for young women with low-grade early ovarian cancer. Fertility-sparing surgery ("FSS") permits the conservation of the uterus and one of the ovaries. This technique is considered safe for stages IA G1, G2 and probably safe for IC G1 epithelial and non-epithelial ovarian cancers. There are still uncertainties and FSS is not fully accepted for stage IC G1, G2 and clear cell carcinoma. The difficulty in choosing the best option lies in the fact that there is a lack of prospective randomized studies, due to ethical and organizational issues. Retrospective studies and reviews showed reassuring results for FSS in terms of relapse and long term survival. The spontaneous pregnancy rate seems to decrease after FSS, but chemotherapy does not seem to have an impact on fertility rates. Compared with the general population, assisted reproductive techniques are considered safe and with similar fertility results.

Reproductive Outcomes and Fertility Preservation Strategies in Women with Malignant Ovarian Germ Cell Tumors after Fertility Sparing Surgery

Malignant ovarian germ cell tumors are rare tumors that mainly affect patients of reproductive age. The aim of this study was to investigate the reproductive outcomes and fertility preservation strategies in malignant ovarian germ cell tumors after fertility-sparing surgery. Data in literature support that fertility-sparing surgery is associated with an excellent oncological outcome not only in early stages malignant ovarian germ cell tumors but also in advanced stages. Moreover, the possibility of performing conservative treatment should be considered even in case of relapse or advanced disease, given the high chemosensitivity. Indeed, available data have shown that menstrual function is maintained after platinum-based regimens in over 85-95% of patients with malignant ovarian germ cell tumors and rate of premature menopause reported in literature ranges between 3% and 7.4%, while premature ovarian failure rates are between 3.4% and 5%. Moreover, reproductive outcomes are about 80% with no increase in the risk of teratogenicity compared to general population. Therefore, conservative surgery for malignant ovarian germ cell tumors currently may represent a therapeutic option in patients who wish to preserve fertility but must be available for extended follow-up and after subscribing to informed consent.

Germinal ovarian tumors in reproductive age women: Fertility-sparing and outcome

MOGCTs (malignant ovarian germ cell tumors) are rare tumors that mainly affect patients of reproductive age. The aim of this study was to evaluate the fertility and survival outcomes in young women with MOCGTs treated with fertility-sparing surgery (FSS).From 2000 to 2018, data from 28 patients of reproductive age with a diagnosis of MOGCT at the University of Bari were collected. Most received FSS, and in patients treated conservatively, the reproductive outcome and survival were investigated. Data of patient demographics, clinical presentation, oncology marker dosage, staging, type of surgery, histological examination, survival, and reproductive outcome were collected from hospital and office charts. All informed consent was obtained from all patients. The median age was 24 (range: 9-45 years). The majority of the patients had stage IIIC. Twenty-four woman received FSS consisting of unilateral ovariectomy and omentectomy, whereas only 4 women, based on their stage (IIIC), received a radical surgery (hysterectomy with bilateral adnexectomy, lymphadenectomy, and omentectomy). Our study shows that FSS in MOGCTs can produce good results both on reproductive outcomes and on survival. Indeed, in our group, there was only 1 case of exitus as result of recurrence. Furthermore, patients after FSS maintained normal ovarian function and 5 of 5 women who tried to get pregnant succeeded spontaneously. The median follow-up was 90 months (range 3-159).Conservative surgery for MOGCTs should be considered for women of reproductive age who wish to preserve fertility.

Fertility sparing surgery for patients with FIGO stage I clear cell ovarian carcinoma: a database analysis and systematic review of the literature

Objective

Fertility sparing surgery for patients with early stage ovarian clear cell carcinoma is controversial. We aimed to investigate the impact of fertility sparing surgery on the oncologic outcomes of young patients with stage I ovarian clear cell carcinoma.

Methods

The National Cancer Database was accessed and patients with pathological stage IA or IC ovarian clear cell carcinoma, aged <45 years, were selected. Based on site specific surgery codes, patients who underwent fertility sparing or radical surgery were identified. Overall survival was evaluated following generation of Kaplan–Meier curves, and compared with the log rank test. Multivariate Cox analysis was performed to control for possible confounders. A systematic review of literature of the Pubmed, EMBASE and Web of Science databases was also performed to summarize all reported cases.

Results

A total of 57 (35.8%) and 102 (64.2%) patients underwent fertility sparing and radical surgery. There was no difference in overall survival between patients who had fertility sparing and radical surgery (p=0.92); 5 year overall survival rates were 89% and 87.9%, respectively. After controlling for the performance of lymphadenectomy and disease substage, fertility sparing surgery was not associated with worse survival (hazard ratio 0.83, 95% confidence interval 0.30 to 2.32). A systematic review of the literature identified 132 patients with stage I disease who underwent fertility sparing surgery; a total of 20 patients (15.2%) experienced a relapse at a median of 18 months from surgery.

Conclusions

In a large cohort of young patients with stage I ovarian clear cell carcinoma, fertility sparing surgery was not associated with worse survival.

Sertoli-Leydig Cell Ovarian Tumors: Is Fertility or Endocrine-Sparing Surgery an Option upon Relapse?

Sertoli-Leydig cell ovarian tumors (SLCT) are rare ovarian tumors of the sex cord-stroma subset. Their incidence peaks in the second to third decade of life. Most SCLT are diagnosed at an early stage and have a good prognosis. Fertility-sparing surgery may thus be offered. Adjuvant chemotherapy may be indicated according to prognostic factors. However, outcome in relapsing SLCT is poor. There is no evidence supporting a best treatment option upon relapse, but most publications combine radical surgery, chemotherapy, and rarely radiotherapy. Two years after left adnexectomy for FIGO IA SLCT, a now 22-year-old patient presented with peritoneal recurrence without involvement of the remaining ovary and uterus. Since there is no evidence of a survival benefit in the literature of macroscopically healthy contralateral ovary ablation in relapse and hormonal replacement therapy is contraindicative, we consented to endocrine-sparing surgery with conservation of the contralateral ovary, followed by 3 cycles of BEP chemotherapy regimen. Our patient is disease-free 16 months after relapse diagnosis. Since recurrence of SLCT has a very poor prognosis and hormonal treatment is contraindicated, endocrine-sparing surgery for young patients with a normal contralateral ovary might be a legitimate option. This is one of the first reported cases of conservative surgery in SLCT recurrence, we therefore aimed to illustrate its management in a young patient with considerations of contraception, fertility- and then endocrine-sparing surgery, and quality of life.

First-Line Treatment with Olaparib for Early Stage BRCA-Positive Ovarian Cancer: May It Be Possible? Hypothesis Potentially Generating a Line of Research

Olaparib is currently approved in maintenance treatment of advanced ovarian cancer after response to first-line chemotherapy for breast related cancer antigens (BRCA) mutated patients. The use of this agent is based on data from SOLO1 study that observed a decreased risk of disease progression or death and a median progression-free survival about 36 months longer in case of therapy with olaparib. However, this trial recruited only patients with advanced stage ovarian cancer. The aim of this review is to retrace the available data in order to clarify the potential efficacy and feasibility of olaparib administration in newly diagnosed epithelial ovarian cancer also in early stages.
