Results of conservative treatment in epithelial ovarian carcinoma

Reproductive and oncological outcomes of fertility-sparing surgery in patients with stage I epithelial ovarian cancer: A systematic review and meta-analysis

OBJECTIVE

We meta-analyzed available evidence on fertility, survival, and cancer recurrence in patients with stage I epithelial ovarian cancer (EOC) after fertility-sparing surgery (FSS).

METHODS

We systematically reviewed PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials to identify studies reporting reproductive and oncological outcomes of patients with stage I EOC who underwent FSS. Random-effects models were used to calculate pooled rates of disease outcomes, along with 95% confidence intervals (CIs). Subgroup and sensitivity analyses were conducted to identify sources of heterogeneity in the data.

RESULTS

We included 23 observational retrospective studies involving 1126 patients. The pooled pregnancy rate was 30% (95% CI, 0.26-0.34), while the pooled natural conception rate was 26% (95% CI, 0.20-0.33). The pooled live birth rate was 27% (95% CI, 0.22-0.32). The pooled rate of EOC recurrence was 12% (95% CI, 0.09-0.14), which did not differ significantly from the rate among patients who underwent radical surgery (odds ratio, 0.77; 95% CI, 0.45-1.33).

CONCLUSIONS

FSS is associated with good oncological outcomes but less than satisfactory reproductive outcomes. All in all, the procedure appears to be a safe alternative to radical surgery for EOC patients who want to preserve fertility.

Oncologic outcomes of uterine preservation for pre-menopausal patients with stage II epithelial ovarian carcinoma

OBJECTIVE

Fertility-sparing surgery is rarely offered for patients with stage II epithelial ovarian carcinoma. The aim of the present study was to evaluate the overall survival of pre-menopausal patients with stage II epithelial ovarian carcinoma who did not undergo hysterectomy.

METHODS

The National Cancer Database was accessed, and patients aged ≤40 years without a history of another tumor diagnosed between 2004 and 2015 with a pathological stage II epithelial ovarian carcinoma, who underwent lymphadenectomy and received multi-agent chemotherapy, were identified. Overall survival was compared with the log-rank test after generation of Kaplan-Meier curves. A Cox model was constructed to control for tumor histology.

RESULTS

A total of 185 patients met the inclusion criteria. The rate of uterine preservation was 24.3% (45 patients). Patients who did not undergo hysterectomy were younger (median 32 vs 37 years, p<0.001) and less likely to have high-grade tumors compared with those who underwent hysterectomy. The two groups were comparable in terms of presence of co-morbidities and performance of adequate lymphadenectomy (p>0.05). Median follow-up of the present cohort was 62.3 months (95% CI 53.6 to 71.0) and a total of 22 deaths occurred. There was no difference in overall survival between patients who did and did not undergo hysterectomy (p=0.50; 5-year overall survival rates 87.5% and 91.4%, respectively). After controlling for tumor histology, grade and substage, omission of hysterectomy was not associated with worse survival (HR 0.69, 95% CI 0.22 to 2.12).

CONCLUSIONS

Uterine preservation was not associated with worse survival in this cohort of pre-menopausal patients with stage II epithelial ovarian carcinoma.

[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).

Clinical and reproductive outcomes of fertility-sparing surgery in stage I epithelial ovarian cancer

The aim of the present study was to evaluate the oncologic safety and reproductive outcome in patients with stage I epithelial ovarian cancer (EOC) treated with fertility-sparing surgery (FSS). Women aged ≤40 years with stage I EOC who had undergone FSS between 2000 and 2010 were retrospectively reviewed. Survival was examined using the Kaplan-Meier method and statistical significance was analyzed using the log-rank test. A total of 29 EOC patients (stage IA, n=14; stage IC1 n=6; stage IC3, n=9) from seven participating institutions belonging to the Tohoku Gynecologic Cancer Unit were enrolled. After a median follow-up duration of 60.6 months (range, 6–135 months), five patients (17.2%) experienced tumor recurrence. The respective five-year relapse-free survival (RFS) and overall survival (OS) rates were 90.9 and 100% for stage IA/IC1, and 43.8 and 87.5% for stage IC3. Significant differences in RFS were observed between stage IA/IC1 and IC3 patients (P=0.026). However, there was no significant difference in OS between patients with 1A/1C1 and those with 1C3 (P=0.712). After FSS, seven pregnancies occurred in five patients, which resulted in the birth of six healthy children. The results of the present study confirmed that FSS may be an acceptable treatment method for stage IA and IC1 EOC, exhibiting a favorable reproductive outcome. However, the safety of FSS for treating stage IC3 EOC is uncertain and warrants further investigation.

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

Level 1-4 (mainly 3-4).

Pregnancy Outcomes after Conservative Surgery for Early-Stage Ovarian Neoplasms

Objective:

This retrospective, single institute study aimed to evaluate pregnancy and oncologic outcomes in reproductive-age Thai women with early-stage ovarian neoplasms undergoing conservative surgical treatment.

Methods:

Medical records of 84 women of reproductive age (15-45 years) with histologically confirmed early-stage (IA-IIC) borderline ovarian tumors or cancers who had undergone conservative surgery between January 2003 and December 2012 were retrospectively reviewed.

Results:

The mean age of patients at diagnosis was 28.0 years (SD 7.2). Histologically, 30 (35.7%) had borderline ovarian tumors, 28 (33.3%) epithelial cancers, 22 (26.2%) malignant germ cell tumors, and 4 (4.8%) sex cord stromal tumors. Thirty-five women (41.7%) had complete surgical staging performed, whereas 49 (58.3%) underwent an incomplete staging procedure. Thirty-four patients (40.5%) received postoperative chemotherapy. Among 29 patients subsequently attempting pregnancy, 15 conceived successfully (51.7%). Pregnancy outcomes were one spontaneous abortion and 14 viable births. There were no serious adverse obstetric and neonatal outcomes among women with documented live births and no reported fetal abnormalities. Pregnancy rates were not impacted by surgical staging (53.8% vs 50.0%, p=0.837) or adjuvant chemotherapy (55.6% vs 50.0%, p=0.782). The 5-year disease-free survival was 91.0% and pregnancy after conservative surgery did not affect progression-free survival (p=0.194).

Conclusion:

Conservative surgery with or without appropriate adjuvant chemotherapy can be offered to young women with early-stage ovarian neoplasms who wish to preserve their fertility potential.

Surgical treatment of early-stage ovarian cancer

The treatment of early-stage (stages I-IIA) ovarian carcinoma is predominantly surgical, and the surgical staging is the most relevant step in the treatment of this disease. The significance of surgical staging is twofold. First, proper staging distinguishes between 'real' early-stage ovarian carcinoma and 'perhaps' early-stage disease. The latter carries an appreciable likelihood of unappreciated residual disease in 16-42% of cases. Second, there is solid proof that proper surgical staging is an independent prognostic factor for improved disease-free and overall survival in early-stage ovarian carcinoma. In this chapter, the relevance of various staging steps is discussed and surgical guidelines are given. The indication for adjuvant chemotherapy after surgery is closely related to the adequacy of surgical staging. Adjuvant chemotherapy only works in patients in whom surgical staging was inadequate and who, thus, remain with a certain risk of unnoticed residual intraperitoneal or retroperitoneal tumour spread. Moreover, there is no indication that adjuvant chemotherapy is of any value after an adequate, comprehensive staging procedure. Controversies and misunderstandings on this important issue are discussed.

Assisted reproductive techniques after fertility-sparing treatments in gynaecological cancers

BACKGROUND

The trend toward late childbearing has made fertility preservation a major issue for women who face gynecological cancer. New techniques in assisted reproductive medicine enable conception after primary treatment of these cancers. Here, we aimed to review the efficacy and safety of assisted reproductive techniques (ART) after fertility-preserving treatment of gynaecological cancers.

METHODS

We conducted a systematic literature review of both prospective and retrospective studies in the PubMed, EMBASE, CENTRAL and SciSearch databases. In the retrieved studies, we evaluated live births, clinical pregnancies, overall survival and disease-free survival.

RESULTS

We identified many prospective and retrospective studies on this topic, but no relevant randomized clinical trials. Fertility-sparing treatments with safe oncological outcomes are feasible in endometrial, cervical and ovarian cancer cases. After cancer treatment, ART seem safe and show variable obstetrical outcomes.

CONCLUSIONS

After fertility-preserving treatment for gynaecological cancers, ART can enable pregnancy to be achieved with apparent oncological safety. The success of such procedures should directly impact clinical practice and management of those patients who require fertility-sparing treatment.

Adjuvant (post-surgery) chemotherapy for early stage epithelial ovarian cancer

BACKGROUND

This is the second update of the review first published in the Cochrane Database of Systematic Reviews in 2009, Issue 1. Epithelial ovarian cancer is diagnosed in over 200,000 women worldwide each year. Ten to 20% of women are diagnosed early, when there is still a good possibility of cure. The treatment of early-stage (stage I and IIa) disease involves surgery to remove the disease, often followed by chemotherapy (adjuvant chemotherapy). The largest clinical trials of adjuvant chemotherapy show an overall survival (OS) advantage with platinum-based chemotherapy; however the precise role and type of this treatment in subgroups of women with differing prognoses needs to be defined.

OBJECTIVES

To undertake a systematic review of the evidence for adjuvant chemotherapy in early-stage epithelial ovarian cancer to determine whether chemotherapy following surgery offers a survival advantage over the policy of observation following surgery (with chemotherapy reserved for treatment of disease recurrence); and to determine if clinical subgroups of women with differing prognoses, based on histological subtype or completeness of surgical staging, have more or less to gain from adjuvant chemotherapy.

SEARCH METHODS

We performed an electronic search using the Cochrane Gynaecological Cancer Specialized Register, Cochrane Central Register of Controlled Trials (CENTRAL 2015, Issue 3), MEDLINE (1948 to March week 5, 2015), and EMBASE (1980 to week 14, 2015). We developed the search strategy using free-text and medical subject headings (MeSH). We also searched registers of clinical trials and citation lists of included studies for potentially relevant studies.

SELECTION CRITERIA

We included randomised clinical trials (RCTs) of women with early stage (I/IIa) epithelial ovarian cancer staged at laparotomy.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed study quality of included RCTs. We resolved any disagreements by discussion with a third review author. We used random-effects methods for all meta-analyses, including subgroup analyses.

MAIN RESULTS

The original version of this Cochrane review included five RCTs involving 1277 women. In this 2015 update, no new studies met the inclusion criteria but we included an additional paper with mature data (10-year follow-up) relating to a previously included study (ICON1).We included four studies in the meta-analyses and considered them to be at a low risk of bias. Most study participants (> 95%) had stage I ovarian cancer. Meta-analysis of five-year data from three studies indicated that women who received adjuvant platinum-based chemotherapy had better overall survival (OS) than those who did not (Hazard ratio (HR) 0.71, 95% confidence interval (CI) 0.53 to 0.93; 1008 women; 3 studies; I² statistic = 0%; high quality evidence). Likewise, meta-analysis of five-year data from four studies indicated that women who received adjuvant chemotherapy had better progression-free survival (PFS) than those who did not (HR 0.67, 95% CI 0.53 to 0.84; 1170 women, 4 studies; I² statistic = 0%; high quality evidence). These findings were robust over time, with 10-year HR estimates of 0.72 (95% CI 0.57 to 0.92; 925 women, 2 studies) and 0.67 (95% CI 0.53 to 0.83; 925 women, 2 studies) for OS and PFS, respectively (high quality evidence). The risk of death at 10 years follow-up favoured the adjuvant chemotherapy arm (0.76, 95% CI 0.62 to 0.94; 923 women, 2 studies; I² statistic = 0%), as did the findings for risk of progression at 10 years (RR 0.72, 95% CI 0.60 to 0.87; 925 women, 2 studies; I² statistic = 0%). Low quality evidence suggested that women with high-risk disease may have the most to gain from adjuvant chemotherapy. However, subgroup analyses could neither confirm nor exclude survival benefits in lower risk disease or in optimally staged disease. We found insufficient data to compare adverse events and long term risks between chemotherapy and observation groups.

AUTHORS' CONCLUSIONS

High-quality evidence indicates that adjuvant platinum-based chemotherapy is effective in prolonging survival in women with early stage (FIGO stage I/IIa) epithelial ovarian cancer. It remains uncertain whether women with low- and intermediate-risk early stage disease will benefit as much from adjuvant chemotherapy as women with high-risk disease. Decisions to use adjuvant chemotherapy (AC) in these women should be mindful of this uncertainty, and the uncertainty regarding adverse events. Treatment of women with lower risk disease should be individualised to take into account individual factors.

Feasibility and efficacy of laparoscopic restaging surgery for women with unexpected ovarian malignancy

OBJECTIVE

To evaluate the feasibility, surgical outcomes and complications of laparoscopic restaging surgery for women with unexpected ovarian malignancy.

STUDY DESIGN

We conducted a retrospective chart review of 14 women with unexpected ovarian malignancy who underwent laparoscopic restaging surgery including peritoneal washing cytology, laparoscopic pelvic and paraaortic lymphadenectomy up to the left renal vein level, omentectomy, and multiple peritoneal biopsies, and hysterectomy except three fertility saving surgery.

RESULTS

The median age and median body mass index women were 49 years (range, 22-63) and 24.2m/kg(2) (range, 18.9-25.3), respectively. The median operating time was 230min (range, 155-370). The median numbers of harvested pelvic and paraaortic lymph nodes were 26 (range, 6-41) and 18 (range, 2-40), respectively. The median return of bowel activity was 28h (range, 21-79). Four of the women were upstaged from the initial presumed stage. There were two intraoperative complications, laceration of the inferior vena cava and cisterna chyli rupture. There was one postoperative complication, port-site metastasis. There was no conversion to laparotomic surgery. The median follow-up period was 33 months. Thirteen of the patients have no evidence of recurrences, however one patient died after 22 months after the surgery.

CONCLUSION

Laparoscopic restaging surgery, performed by a specialized laparoscopic oncologist with sufficient laparoscopic experience and a well-trained operating team, is both feasible and effective in the management of unexpected ovarian malignancies.

Fertility sparing surgery in early stage epithelial ovarian cancer

Objective

Fertility sparing surgery (FSS) is a strategy often considered in young patients with early epithelial ovarian cancer. We investigated the role and the outcomes of FSS in eEOC patients who underwent comprehensive surgery.

Methods

From January 2003 to January 2011, 24 patients underwent fertility sparing surgery. Eighteen were one-to-one matched and balanced for stage, histologic type and grading with a group of patients who underwent radical comprehensive staging (n=18). Demographics, surgical procedures, morbidities, pathologic findings, recurrence-rate, pregnancy-rate and correlations with disease-free survival were assessed.

Results

A total of 36 patients had a complete surgical staging including lymphadenectomy and were therefore analyzed. Seven patients experienced a recurrence: four (22%) in the fertility sparing surgery group and three (16%) in the control group (p=not significant). Sites of recurrence were: residual ovary (two), abdominal wall and peritoneal carcinomatosis in the fertility sparing surgery group; pelvic (two) and abdominal wall in the control group. Recurrences in the fertility sparing surgery group appeared earlier (mean, 10.3 months) than in radical comprehensive staging group (mean, 53.3 months) p<0.001. Disease-free survival were comparable between the two groups (p=0.422). No deaths were reported. All the patients in fertility sparing surgery group recovered a regular period. Thirteen out of 18 (72.2%) attempted to have a pregnancy. Five (38%) achieved a spontaneous pregnancy with a full term delivery.

Conclusion

Fertility sparing surgery in early epithelial ovarian cancer submitted to a comprehensive surgical staging could be considered safe with oncological results comparable to radical surgery group.

Building a successful fertility preservation program at a major cancer center

Over 150,000 reproductive age individuals face fertility-threatening cancer treatments each year. Improved detection and treatment of cancer in reproductive-age patients have greatly increased the long-term survival and made it possible for these individuals to consider their long-term quality-of-life after cancer including having biologic offspring. Various methods of fertility preservation (FP) are now available for both males and females. In order to maximize FP options available to patients facing imminent gonadotoxic therapies, it is crucial that women have quick access to FP care and that providers expedite FP strategies. The overarching goal of a clinical FP program is to help patients and their physicians consider the impact of treatment on future fertility and facilitate FP efforts in what is often a limited time period before cancer treatment begins.

Association Between Reproductive Cancer and Fetal Outcomes: A Systematic Review

Objective

This study aimed to review studies that addressed the impact of previous reproductive cancer diagnosis on selected fetal birth outcomes.

Materials and Methods

We searched PubMed and Web of Knowledge to identify peer-reviewed articles published from January 1992 to December 2012, investigating the association between reproductive cancer and birth outcomes. After applying exclusion criteria, 49 articles were identified for full review, and 36 articles were finally selected for this systematic review. The quality of the studies was assessed by independent reviewers.

Results

We found 13 cervical cancer studies, 16 ovarian cancer studies, and 7 corpus uteri cancers that reported subsequent pregnancies (n = 688 pregnancies in 477 women). Of these, 489 pregnancies reached third trimester. Among viable pregnancies, only 416 pregnancies had information on maturity status based on gestational age and/or birth weight. For those with cervical cancer, the preterm birth (PTB) rate was 48.5%. For those with ovarian cancer, there were no cases of PTB. For those with corpus uteri cancers, the PTB was 7.7%. All studies had small sample sizes, and there was considerable heterogeneity of results. Abortions, ectopic pregnancies, and terminations were also reported.

Conclusions

Reproductive cancers may be associated to subsequent adverse fetal birth outcomes; however, the quality of evidence is still insufficient to infer a relationship between reproductive cancers treated conservatively and adverse fetal birth outcomes in subsequent pregnancies.

Surgical management of epithelial ovarian cancer

Ovarian cancer affects approximately 21,880 women and accounts for over 13,000 deaths annually in the United States. Although survival rates have improved over the past several decades, directly as a result of advances in chemotherapy and surgery, ovarian cancer continues to have high mortality rates. Understanding the multiple roles of surgery throughout the disease course is the focus of this review.

Adjuvant (post-surgery) chemotherapy for early stage epithelial ovarian cancer

BACKGROUND

Epithelial ovarian cancer is diagnosed in 4500 women in the UK each year of whom 1700 will ultimately die of their disease.Of all cases 10% to 15% are diagnosed early when there is still a good possibility of cure. The treatment of early stage disease involves surgery to remove disease often followed by chemotherapy. The largest clinical trials of this adjuvant therapy show an overall survival (OS) advantage with adjuvant platinum-based chemotherapy but the precise role of this treatment in subgroups of women with differing prognoses needs to be defined.

OBJECTIVES

To systematically review the evidence for adjuvant chemotherapy in early stage epithelial ovarian cancer to determine firstly whether there is a survival advantage of this treatment over the policy of observation following surgery with chemotherapy reserved for treatment of disease recurrence, and secondly to determine if clinical subgroups of differing prognosis based on histological sub-type, or completeness of surgical staging, have more or less to gain from chemotherapy following initial surgery.

SEARCH METHODS

We performed an electronic search using the Cochrane Gynaecological Cancer Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL 2011, Issue 3), MEDLINE (1948 to Aug week 5, 2011) and EMBASE (1980 to week 36, 2011). We developed the search strategy using free-text and medical subject headings (MESH).

SELECTION CRITERIA

We selected randomised clinical trials that met the inclusion criteria set out based on the populations, interventions, comparisons and outcome measures.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed trial quality. Disagreements were resolved by discussion with a third review author. We performed random-effects meta-analyses and subgroup analyses.

MAIN RESULTS

Five randomised controlled trials (RCTs), enrolling 1277 women, with a median follow-up of 46 to 121 months, met the inclusion criteria. Four trials were included in the meta-analyses and we considered them to be at a low risk of bias. Meta-analysis of five-year data from three trials indicated that women who received adjuvant platinum-based chemotherapy had better overall survival (OS) than those who did not (1008 women; hazard ratio (HR) 0.71; 95% confidence interval (CI) 0.53 to 0.93). Likewise, meta-analysis of five-year data from four trials indicated that women who received adjuvant chemotherapy had better progression-free survival (PFS) than those who did not (1170 women; HR 0.67; 95% CI 0.53 to 0.84). The trials included in these meta-analyses gave consistent estimates of the effects of chemotherapy. In addition, these findings were robust over time (10-year PFS: two trials, 925 women; HR 0.67; 95% CI 0.54 to 0.84).Subgroup analysis suggested that women who had optimal surgical staging of their disease were unlikely to benefit from adjuvant chemotherapy (HR for OS 1.22; 95% CI 0.63 to 2.37; two trials, 234 women) whereas those who had sub-optimal staging did (HR for OS 0.63; 95% CI 0.46 to 0.85; two trials, 772 women). One trial showed a benefit from adjuvant chemotherapy among women at high risk (HR for OS 0.48; 95% CI 0.32 to 0.72) but not among those at low/medium risk (HR for OS 0.95; 95% CI 0.54 to 1.66). However, these subgroup findings could be due to chance and should be interpreted with caution.

AUTHORS' CONCLUSIONS

Adjuvant platinum-based chemotherapy is effective in prolonging the survival of the majority of patients who are assessed as having early (FIGO stage I/IIa) epithelial ovarian cancer. However, it may be withheld from women in whom there is well-differentiated encapsulated unilateral disease (stage 1a grade 1) or those with comprehensively staged Ib, well or moderately differentiated (grade 1/2) disease. Others with unstaged early disease or those with poorly differentiated tumours should be offered chemotherapy. A pragmatic approach may be necessary in clinical settings where optimal staging is not normally performed/achieved. In such settings, adjuvant chemotherapy may be withheld from those with encapsulated stage Ia grade 1 serous and endometrioid carcinoma and offered to all others with early stage disease.

Fertility-sparing surgery in early epithelial ovarian cancer: a viable option?

Epithelial ovarian cancer (EOC) continues to represent one of the most lethal conditions in women in the western countries. With the shifting of childbearing towards higher age, EOC increasingly affects women with active childbearing wish, resulting in major impacts on treatment management. Next to the optimal therapeutic treatment strategies, gynecologic oncologists are being asked to incorporate into their decision-making processes the patients' wish for fertility preserving alternatives ideally without compromising oncologic safety. Nowadays, fertility-sparing surgery represents an effective alternative to conventional radical cytoreduction in younger women with early stages of the disease. As such, this paper considers indications for fertility sparing surgery in EOC, reflects on outcomes from the oncologic and reproductive data of the largest and most relevant series outcomes data, reporting on fertility sparing techniques in EOC, reviews medicamentous efforts to prevent chemotherapy induced gonadotoxicity, and discusses future aspects in the gynecologic cancer management.

Clinical outcomes of fertility-sparing treatments in young patients with epithelial ovarian carcinoma

OBJECTIVE

To assess the clinical outcomes of fertility-sparing treatments in young patients with epithelial ovarian carcinoma (EOC).

METHODS

A retrospective study of young EOC inpatients (≤40 years old) was performed during January 1994 and December 2010 in eight institutions.

RESULTS

Data were analyzed from 94 patients treated with fertility-sparing surgery with a median follow-up time of 58.7 months. As histologic grade increased, overall survival (OS) and disease-free survival (DFS) of patients receiving fertility-sparing surgery declined. Neither staging surgery nor laparoscopy of early stage EOC with conservative surgery had a significant effect on OS or DFS. Normal menstruation recommenced after chemotherapy in 89% of the fertility-sparing group. Seventeen pregnancies among twelve patients were achieved by the end of the follow-ups.

CONCLUSIONS

Fertility-sparing treatment for patients with EOC Stage I Grade 1 could be cautiously considered for young patients. The surgical procedure and surgical route might not significantly influence the prognosis. Standard chemotherapy is not likely to have an evident impact on ovarian function or fertility in young patients.

Long-term survival of young women receiving fertility-sparing surgery for ovarian cancer in comparison with those undergoing radical surgery

Objectives:

To compare the clinical outcome of patients with stage I epithelial ovarian cancer (EOC) who received with fertility-sparing surgery (FSS) with those who underwent radical surgery (RS).

Methods:

After a central pathological review and search of the medical records from multiple institutions, a total of 572 patients were retrospectively evaluated. All patients were divided into three groups: group A {FSS (n=74); age, ⩽40} groups B and C [RS; age, 40⩾{(B), n=52} 40<{(C), n=446}].

Results:

Five-year overall survival (OS) and disease-free survival (DFS) rates of patients in the groups were as follows: group A, 90.8% (OS)/87.9% (DFS); group B, 88.3% (OS)/84.4% (DFS); group C, 90.6% (OS)/85.3% (DFS), respectively (OS, P=0.802; DFS, P=0.765). Additionally, there was no significant difference in OS and DFS among the three groups stratified to stage IA or IC (OS (IA), P=0.387; DFS (IA), P=0.314; OS (IC), P=0.993; DFS (IC), P=0.990, respectively). Furthermore, patients with a grade 1–2 or 3 tumours in the FSS group did not have a poorer prognosis than those in the RS group.

Conclusions:

Stage I EOC patients treated with FSS showed an acceptable prognosis compared with those who underwent RS.

Fertility preserving options in patients with gynecologic malignancies

A proportion of reproductive age women are affected by gynecologic malignancies. This patient population is faced with difficult decisions, related to their cancer care and treatment, as well as future childbearing potential. Therefore, it is important for gynecologists to be familiar with fertility sparing management options in patients with cervical, ovarian, and endometrial cancer. In addition to understanding the surgical approaches available, providers should be able to counsel patients regarding their eligibility for and the indications and limitations of fertility sparing therapy for gynecologic cancer, allowing for appropriate referrals. A comprehensive PUBMED literature search was conducted using the key words "fertility preservation," "cervical cancer," "endometrial cancer," "ovarian cancer," "borderline tumor of the ovary," "germ cell tumor," "obstetrical outcomes," "chemotherapy," and "radiation." The following review summarizes fertility sparing options for patients with cervical, ovarian and endometrial cancer, with an emphasis on appropriate patient selection, oncologic, and obstetric outcomes.

Fertility-sparing surgery in young women with mucinous adenocarcinoma of the ovary

OBJECTIVES

The purpose of this study was to clarify the clinical outcome of patients with stage IA mucinous epithelial ovarian cancer (mEOC) treated with fertility-sparing surgery (FSS).

METHODS

After a central pathological review and search of the medical records from multiple institutions, a total of 148 stage I mEOC patients were retrospectively evaluated in the current study. All mEOC patients were divided into three groups: group A (FSS; age, 40≥); groups B and C {radical surgery; age, 40≥ (B); 40< (C)}. Survival analysis was performed among these three groups using Kaplan-Meier methods.

RESULTS

The median follow-up time of all mEOC patients was 71.6 (4.8-448.3) months. Among the 41 patients in group A, 27 patients (65.9%) had IA disease, and 14 (34.1%) had IC disease. Five-year overall survival (OS) and disease-free survival (DFS) rates of patients in the groups were as follows: group A, 97.3% (OS)/90.5% (DFS); group B, 94.4% (OS)/94.4% (DFS); group C; 97.3% (OS)/89.3% (DFS). Collectively, there was no significant difference in OS or DFS among these groups even though they were stratified to each substage (IA/IC) (OS, P=0.180; DFS, P=0.445, respectively). Furthermore, in multivariate analyses, the surgical procedure was not an independent prognostic factor for either OS or DFS (OS, HR: 0.340, 95% CI: 0.034-3.775, P=0.352; DFS, HR: 0.660, 95% CI: 0.142-3.070, P=0.596).

CONCLUSIONS

Patients with stage I mEOC treated with FSS did not necessarily show a poorer prognosis than those receiving radical surgery.

Pregnancy outcomes after conservative surgical management of ovarian neoplasms treated at a single institution

HYPOTHESIS

Conservative surgical management of ovarian neoplasms can result in favorable oncologic and obstetric outcomes.

METHODS

All reproductive-age women (18-45 years old) with stage IA to stage IIC ovarian neoplasms (N = 161) were retrospectively identified from a single institution's tumor registry between 1990 and 2007. Operative, pathological, outpatient, and delivery records were reviewed to confirm histological findings, stage, extent of surgical resection, adjuvant treatment, oncologic outcomes, and pregnancy outcomes.

RESULTS

Women who underwent conservative surgical management for ovarian neoplasms (n = 61 [37.9%]) were identified, including those with low malignant potential (LMP, n = 36), epithelial (n = 12), germ cell (n = 6), and sex cord (n = 7) tumors. Thirteen women conceived 23 pregnancies, producing a pregnancy rate of 25.0% overall and of 68.4% for those attempting conception. Women with LMP tumors conceived most pregnancies and had the highest number of antenatal complications. Of those receiving adjuvant chemotherapy (n = 8), 12.5% were able to conceive after their treatment and with no reported congenital anomalies. Pregnancy after a diagnosis of ovarian neoplasm did not impact disease recurrence (0% vs 7.7%, P = 0.56) or survival (100% vs 100%, P = 1.0).

CONCLUSIONS

Conservative surgery may be an acceptable option for reproductive-age women with early-stage ovarian neoplasms. We report pregnancy and oncologic outcomes for a cohort of women managed conservatively for LMP, epithelial, germ cell, and sex cord ovarian neoplasms.

Chemotherapy for gynecologic cancers

This review highlights significant recent developments and trends in chemotherapy for major gynecologic malignancies, i.e., ovarian cancer, endometrial cancer, uterine sarcomas, gestational trophoblastic neoplasia, and cervical cancer. In ovarian cancer, chemotherapeutic options for early, advanced and recurrent disease are in the adjuvant setting as well as in the neoadjuvant setting are explored. For uterine cancer, adjuvant chemotherapy is employed for high risk epithelial subtypes with early disease, such as uterine papillary serous carcinomas, uterine carcinosarcomas and leiomyosarcomas, advanced stage cases, as well as recurrent disease. The review then proceeds to further discuss the appropriate treatment based on the International Federation of Gynecology and Obstetrics prognostic scoring system for gestational trophoblastic neoplasia. Finally, chemotherapy is utilized in cervical cancer as neo-adjuvant therapy prior to surgery or radiation, as a sensitizer concomitantly with radiation therapy or for the treatment of advanced and recurrent disease.

Outcomes of Fertility-Sparing Surgery for Stage I Epithelial Ovarian Cancer: A Proposal for Patient Selection

Purpose

The objective of this study was to assess clinical outcomes and fertility in patients treated conservatively for unilateral stage I invasive epithelial ovarian cancer (EOC).

Patients and Methods

A multi-institutional retrospective investigation was undertaken to identify patients with unilateral stage I EOC treated with fertility-sparing surgery. Favorable histology was defined as grade 1 or grade 2 adenocarcinoma, excluding clear cell histology.

Results

A total of 211 patients (stage IA, n = 126; stage IC, n = 85) were identified from 30 institutions. Median duration of follow-up was 78 months. Five-year overall survival and recurrence-free survival were 100% and 97.8% for stage IA and favorable histology (n = 108), 100% and 100% for stage IA and clear cell histology (n = 15), 100% and 33.3% for stage IA and grade 3 (n = 3), 96.9% and 92.1% for stage IC and favorable histology (n = 67), 93.3% and 66.0% for stage IC and clear cell histology (n = 15), and 66.7% and 66.7% for stage IC and grade 3 (n = 3). Forty-five (53.6%) of 84 patients who were nulliparous at fertility-sparing surgery and married at the time of investigation gave birth to 56 healthy children.

Conclusion

Our data confirm that fertility-sparing surgery is a safe treatment for stage IA patients with favorable histology and suggest that stage IA patients with clear cell histology and stage IC patients with favorable histology can be candidates for fertility-sparing surgery followed by adjuvant chemotherapy.

Fertility preservation in young women with epithelial ovarian cancer

BACKGROUND

Surgical management of ovarian cancer consists of hysterectomy with bilateral oophorectomy. In young women, this results in the loss of reproductive function and estrogen deprivation. In the current study, the authors examined the safety of fertility-conserving surgery in premenopausal women with epithelial ovarian cancers.

METHODS

Women aged<or=50 years with stage IA or IC epithelial ovarian cancer who were registered in the Surveillance, Epidemiology, and End Results database were examined. Patients who underwent bilateral oophorectomy were compared with those who underwent ovarian conservation. A second analysis examined uterine conservation versus hysterectomy. Multivariate Poisson regression models were developed to describe predictors of fertility preservation. Survival was examined using Cox proportional hazards models and the Kaplan-Meier method.

RESULTS

In total, 1186 women, including 754 women (64%) who underwent bilateral oophorectomy and 432 women (36%) who underwent ovarian preservation, were identified. Younger age, later year of diagnosis, and residence in the eastern or western United States were associated with ovarian preservation (P<.05 for all). Women with endometrioid and clear cell histologies and stage IC disease were less likely to have ovarian conservation (P<.05). In a Cox model, ovarian preservation had no effect on survival (hazard ratio [HR], 0.69; 95% confidence interval [CI], 0.39-1.20). Young age, later year of diagnosis, residence in the eastern or western United States, single women, mucinous tumors, and patients with stage IA disease were more likely to have uterine preservation (P<.05 for all). In a multivariate model, uterine preservation had no effect on survival (HR, 0.87; 95% CI, 0.62-1.22).

CONCLUSIONS

Ovarian and uterine-conserving surgery were safe in young women who had stage IA and IC epithelial ovarian cancer.

Adjuvant (post-surgery) chemotherapy for early stage epithelial ovarian cancer

BACKGROUND

Epithelial ovarian cancer is diagnosed in 4500 women in the UK each year of whom 1700 will ultimately die of their disease. Ten to fifteen percent of all cases are diagnosed early when there is still a good possibility for cure. The treatment of early stage disease involves surgery to remove disease often followed by chemotherapy. The largest clinical trials of this adjuvant therapy show an overall survival (OS) advantage with adjuvant platinum based chemotherapy but the precise role of this treatment in sub-groups of patients with differing prognoses needs to be defined.

OBJECTIVES

To systematically review the evidence for adjuvant chemotherapy in early stage epithelial ovarian cancer to determine; firstly whether there is a survival advantage of this treatment over the policy of observation following surgery with chemotherapy reserved for treatment of disease recurrence, and secondly; to determine if clinical sub-groups of differing prognosis based on histological sub-type or completeness of surgical staging, have more or less to gain from chemotherapy following initial surgery.

SEARCH STRATEGY

An electronic search was performed using the Cochrane Gynaecological Cancer Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL, Issue 2, 2008), MEDLINE (1966 to 2008), EMBASE (1980 to 2008) and CancerLit. The search strategy was developed using free text and medical subject headings (MESH).

SELECTION CRITERIA

The review authors selected those clinical trials that met the inclusion criteria set out based on the populations, interventions, comparisons and outcome measures.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed trial quality. Disagreements were resolved by discussion with a third review author. Random effects meta-analyses and sub-group analyses were conducted.

MAIN RESULTS

Five randomised controlled trials (RCTs), enrolling 1277 women, with 46 to 110 months follow-up, met the inclusion criteria. These trials had low risk of bias. Meta-analysis of three trials with adequate data, assessing 1008 women, indicated that women who received adjuvant platinum-based chemotherapy had better overall survival (OS) than those who did not (hazard ratio (HR) 0.71; 95% CI 0.53 to 0.93). Likewise, meta-analysis of four trials with adequate data, assessing 1170 women, indicated that women who received adjuvant chemotherapy had better progression-free survival (PFS) than those who did not (HR 0.67; 95% CI 0.53 to 0.84). The trials included in these meta-analyses gave consistent estimates of the effects of chemotherapy.Sub-group analysis suggested that women who had optimal surgical staging of their disease were unlikely to benefit from adjuvant chemotherapy (HR for OS 1.22; 95% CI 0.63 to 2.37) whereas those who had sub-optimal staging did (HR for OS 0.63; 95% CI 0.46 to 0.85). One trial showed a benefit from adjuvant chemotherapy among women at high risk (HR for OS 0.48; 95% CI 0.32 to 0.72) but not among those at low risk (HR for OS 0.95; 95% CI 0.54 to 1.66). However, these sub-group findings could be due to chance.

AUTHORS' CONCLUSIONS

Adjuvant platinum based chemotherapy is effective in prolonging the survival of the majority of patients who are assessed as having early stage epithelial ovarian cancer. However, even given the limits of sub-group analyses, there is strong evidence that optimal surgical staging identifies patients who have either little or nothing to gain from adjuvant chemotherapy. Taken together with the lack of a survival advantage seen in patients with "low-risk" cancers in the ICON1 trial, it appears safe to withhold adjuvant chemotherapy from optimally staged patients with well differentiated tumours.

Long-term follow-up results of fertility sparing surgery in patients with epithelial ovarian cancer

BACKGROUND AND OBJECTIVE

To assess clinical and obstetric outcome in young patients with epithelial ovarian cancer treated with fertility sparing surgery.

METHODS

Eighteen patients younger than 40 years carrying epithelial ovarian tumors were submitted to fertility sparing surgery between 1988 and 2003. Disease-free (DFS) and overall survival (OS) were analyzed using the Kaplan-Meier method. Statistical analysis was performed with the chi(2) test.

RESULTS

Disease free survival (DFS) 83.3% and overall survival (OS) 94.4% of patients treated with conservative surgery at 10 years. Up to date, six of seven patients who attempted pregnancy delivered seven healthy newborns.

CONCLUSION

Conservative surgery in young women with epithelial ovarian cancer is an appropriate therapeutic option in patients who wish to preserve childbearing potential. Long-term follow-up results shows excellent overall survival and pregnancy results.

Current status of the approach to assisted reproduction

Assisted reproductive technologies are important tools in the clinical armamentarium used to treat both female and male infertility disorders. Pre-implantation genetic diagnosis offers couples at risk of having children with inheritable disorders the ability to analyze the genetic make-up of embryos before transfer. For patients undergoing treatment of cancer with chemotherapy or radiation therapy, these technologies offer the potential for the preservation of future fertility. As technology evolves, it is likely the clinical applications of assisted reproduction will continue to develop and expand in the future to enhance fertility.

The search strategy was developed using free text and medical subject headings (MESH). This yielded a large number of article titles which were sifted down by two review authors to a limited number of articles, the full text versions of which were independently reviewed to select out clinical trials of direct and specific relevance to the review question. Hand searches of the clinical literature were conducted where appropriate to identify additional full-text papers or abstracts of other directly relevant clinical trials.

Outcomes of fertility-sparing surgery for invasive epithelial ovarian cancer: oncologic safety and reproductive outcomes

OBJECTIVE

Younger patients with invasive epithelial ovarian cancer (EOC) frequently want to preserve their fertility, but the role of fertility-sparing surgery in EOC has not been well defined. We therefore assessed tumor recurrence, patient survival and pregnancy outcomes in patients with invasive EOC who underwent fertility-sparing surgery.

METHODS

Records of 62 patients with invasive EOC who underwent fertility-sparing surgery, defined as the preservation of ovarian tissue in one or both adnexa and the uterus, between May 1990 and October 2006, were retrospectively reviewed.

RESULTS

Of the 62 EOCs, 36 were stage IA, 2 were stage IB, 21 were stage IC, and 1 each was stage IIB, IIIA, and IIIC; 48 were grade I, 5 were grade II, and 9 were grade III. Forty-eight patients received platinum-based adjuvant chemotherapy (mean 4.6 cycles, range 1-9 cycles). At a median follow-up of 56 months (range, 6-205 months), 11 patients had tumor recurrence, 6 died of disease, 2 were alive with disease, and 54 were alive without disease. Patients with stage >IC (p=0.0014) or grade III (p=0.0002) tumors had significantly poorer survival. Nineteen women attempted to conceive, and there were 22 term pregnancies, with no congenital anomalies in any of the offspring.

CONCLUSION

Fertility-sparing surgery can be considered in young patients with stages IA-C and grades I-II EOCs who desire to preserve their fertility.

Laparoscopic fertility-sparing staging in unexpected early stage ovarian malignancies

OBJECTIVE

To assess feasibility and safety of fertility-sparing laparoscopic staging in women affected by unexpected ovarian cancer desiring to preserve their fertility.

DESIGN

Prospective study.

SETTING

University clinic.

PATIENT(S)

Twenty-seven patients already operated on elsewhere for a presumably benign ovarian cyst.

INTERVENTION(S)

Laparoscopic fertility-sparing staging operations.

MAIN OUTCOME MEASURE(S)

Perioperative and survival data, reproductive outcome.

RESULT(S)

Histologic findings after first surgery: 12 low malignant potential neoplasms, 11 invasive epithelial ovarian carcinomas,1 sex-cord stromal, and 3 germ cell neoplasms. Fertility-sparing staging consisted of exploration of the peritoneal cavity, peritoneal washing cytology, multiple peritoneal biopsies, omolateral adnexectomy (except in borderline tumors), omentectomy, omolateral or bilateral pelvic and aortic lymph node sampling (except in borderline tumors, well differentiated, mucinous, and granulosa cell (GC) neoplasms), endometrial biopsy, appendectomy in mucinous type. Overall, seven patients (26%) were upstaged. Six patients received adjuvant platinum-based chemotherapy. Two term pregnancies occurred. After a median follow-up of 20 months all patients are alive; one patient has FIGO stage Ic clear cell carcinoma, which recurred 8 months after surgery.

CONCLUSION(S)

Laparoscopic fertility-sparing staging in early ovarian malignancies is feasible and safe in selected and counseled patients and should be performed in experienced gynecological oncology centers trained in endoscopic procedures.

Adjuvant chemotherapy for early-stage ovarian cancer: review of the literature

PURPOSE

This overview summarizes studies with acceptable quality and validity and presents a synthesis of the effectiveness on adjuvant therapy after surgery for early ovarian cancer (EOC) patients.

METHODS

The literature published between 1970 and 2006 was identified systematically by computer-based searches in MEDLINE and Cochrane library.

RESULTS

Twenty-two prospective randomized studies were analyzed, which included 4,626 patients. No difference between adjuvant chemotherapy (AC) and radiotherapy was found. There is agreement on that patients with stage IA, grade 1 tumors have excellent survival and do not need postsurgical therapy. The International Collaborative Ovarian Neoplasm 1/Adjuvant Chemotherapy in Ovarian Neoplasm trials were the first to show an effect on survival of AC, but in patients with adequate surgical staging, there was no additional effect of AC. For patients who are staged incompletely at the time of initial surgery, completion of the staging procedure with either laparoscopy or laparotomy is a reasonable approach before a final decision is made regarding the need for AC. If full staging cannot be performed due to medical contraindication or patient refusal, consideration of AC is reasonable in selected patients. Using prognostic variables such as grade, International Federation of Gynecology and Obstetrics substage, pretreatment of CA-125 < or = 30 U/mL, and DNA ploidy, it is possible to divide patients into risk groups to avoid overtreatment. Gynecologic Oncology Group study 157 suggests that it may be possible to minimize chemotherapy-induced toxicity by using three instead of six cycles of AC, although it is not known fully whether this will compromise effectiveness.

CONCLUSION

Future randomized studies in EOC will include the investigation of new targeted therapies and new prognostic factors in adequately staged patients.

Reproduction beyond cancer: A message of hope for young women

OBJECTIVE

Aggressive chemotherapy and radiotherapy or radical oncological surgery in young women with cancer has greatly enhanced these patients' life expectancy, but these treatments often cause infertility or premature ovarian failure due to a massive destruction of the ovarian reserve. The objective of this review is to discuss the effect of the various cancer treatments on fertility and present the various fertility sparing operations and fertility preservation strategies.

METHOD

An extensive survey of the most up-to-date literature was performed.

RESULTS

This review discusses the impact of current cancer treatment on fertility potential and the various surgical and assisted-reproduction innovations available today for the most common cancers in young women. Although the ability to retain reproductive potential is becoming a major quality-of-life factor in an increasing number of young female cancer survivors, they are still being poorly counseled with regard to the negative impact of the treatment on their fertility and on their options for fertility preservation.

CONCLUSION

As the emerging discipline of fertility preservation is steadily attracting increasing interest, developments in the near future promise to be very exciting. However, in everyday routine work, better interdisciplinary cooperation between gynecological and pediatric oncologists, surgeons, immunologists, and endocrinologists is necessary so that individualized options for fertility preservation can be offered in advance of surgical procedures or cancer treatments.
