Current Status of Fertility Preservation in Pediatric Oncology Patients. CHILDREN (BASEL, SWITZERLAND) 2024; 11:537. [PMID: 38790532 PMCID: PMC11120648 DOI: 10.3390/children11050537] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/15/2024] [Revised: 04/25/2024] [Accepted: 04/29/2024] [Indexed: 05/26/2024]
Abstract
Cancer poses significant emotional challenges for children and adolescents, despite improvements in survival rates due to new therapies. However, there is growing concern about the long-term effects, including fertility issues. This review examines recent advancements and future directions in fertility preservation within a pediatric population subjected to oncological therapies. Worldwide, there is variability in the availability of fertility preservation methods, influenced by factors like development status and governmental support. The decision to pursue preservation depends on the risk of gonadotoxicity, alongside factors such as diagnosis, treatment, clinical status, and prognosis. Currently, options for preserving fertility in prepubertal boys are limited compared to girls, who increasingly have access to ovarian tissue preservation. Adolescents and adults have more options available, but ethical considerations remain complex and diverse.

An update on oncofertility in prepubertal females. J Gynecol Obstet Hum Reprod 2024; 53:102742. [PMID: 38341083 DOI: 10.1016/j.jogoh.2024.102742] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 02/02/2024] [Accepted: 02/08/2024] [Indexed: 02/12/2024]
Abstract
Cancer is a life-threatening event for pediatric patients. Treatment advancements in pediatric cancer have improved prognosis, but some of these treatments have gonadotoxic potential and may affect fertility in different ways. Due to the growing interest of the research community in the life prospects of young cancer survivors, there has been a demand to intersect reproductive medicine and oncology, which is referred to as "oncofertility". There are various fertility preservation options according to gender and pubertal status, and shared decisions must take place at the time of diagnosis. This study aims to provide a critical review of current and emerging strategies for preserving and restoring fertility in prepubertal females, ranging from established methods to experimental approaches that can be offered before, during, and after anticancer therapies. Additionally, the author aims to review how clinicians' awareness of oncofertility options and the latest advancements in this field, timely referral, and proper consultations with patients and their families are vital in addressing their concerns, providing emotional support, and guiding them through the decision-making process, as well as potential barriers that may hinder the fertility preservation process.

Ethical, legal, social, and policy issues of ovarian tissue cryopreservation in prepubertal girls: a critical interpretive review. J Assist Reprod Genet 2024; 41:999-1026. [PMID: 38430324 PMCID: PMC11052756 DOI: 10.1007/s10815-024-03059-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Accepted: 02/07/2024] [Indexed: 03/03/2024] Open
Abstract
PURPOSE Despite the increasing number of childhood cancer survivors, significant advances in ovarian tissue cryopreservation (OTC) technique and medical societies' recommendations, fertility preservation (FP) and FP discussions are not always offered as a standard of care in the pediatric context. The aim of this literature review is to understand what ethical, legal, social, and policy issues may influence the provision of FP by OTC in prepubertal girls with cancer. METHODS A critical interpretive review of peer-reviewed papers published between 2000 and January 2023 was conducted, guided by the McDougall's version of the critical interpretive synthesis (Dixon-Woods), to capture recurring concepts, principles, and arguments regarding FP by OTC for prepubertal girls. RESULTS Of 931 potentially relevant papers, 162 were included in our analysis. Data were grouped into seven thematic categories: (1) risks of the procedure, (2) unique decision-making issues in pediatric oncofertility, (3) counseling, (4) cultural and cost issues, and (5) disposition of cryopreserved reproductive tissue. CONCLUSION This first literature review focusing on ethical, legal, social, and policy issues surrounding OTC in prepubertal girls highlights concerns in the oncofertility debate. Although OTC is no longer experimental as of December 2019, these issues could limit its availability and the child's future reproductive autonomy. This review concludes that specific actions must be provided to enable the offer of FP, such as supporting families' decision-making in this unique and complex context, and providing pediatric patients universal and full access to free or highly subsidized OTC.

Features of Studies on Transition Interventions for Childhood Cancer Survivors: A Scoping Review. Cancers (Basel) 2024; 16:272. [PMID: 38254763 PMCID: PMC10814357 DOI: 10.3390/cancers16020272] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2023] [Revised: 12/29/2023] [Accepted: 01/02/2024] [Indexed: 01/24/2024] Open
Abstract
PURPOSE in this scoping review, previously reported data were described and synthesized to document transition interventions in CCSs, and the features of intervention components of the current transition studies for CCSs were summarized. METHODS A literature search was conducted in PubMed, Web of Science, EMBASE, PsycINFO, CINAHL, Ovid, and the Cochrane Library following the PRISMA-ScR statement. All original studies (n = 9) investigating transition interventions in CCSs were included. RESULTS The current studies identified essential elements for transition programs, such as delivering knowledge, developing skills for coordination of care, and addressing psychosocial needs. However, the current transition interventions were generally in their infancy, and major deficits were found, including poorly reported intervention components and procedures, a limited number of relevant validated outcomes, and a failure to incorporate conceptual frameworks and international consensus statements. CONCLUSIONS This scoping review mapped current evidence of transition interventions for CCSs and highlighted the paucity of data in this area. More high-quality and well-reported randomized controlled trials are needed for the enrichment and standardization of future transition interventions.

The study of the efficiency of in vitro maturation of ovarian tissue oocytes in pediatric patients. J Assist Reprod Genet 2023; 40:2787-2797. [PMID: 37779181 PMCID: PMC10656375 DOI: 10.1007/s10815-023-02958-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2023] [Accepted: 09/21/2023] [Indexed: 10/03/2023] Open
Abstract
PURPOSE Although recent in vitro maturation (IVM) studies in pediatric patients have demonstrated successful retrieval and maturation of oocytes, the studies included only a small number of premenarchal patients. In the present study, we examined the potential use of oocyte retrieval and maturation for pediatric patients who undergo ovarian tissue cryopreservation (OTC). METHODS We retrospectively examined the clinical records of pediatric patients who underwent OTC at our institution between October 2015 and December 2022. Data on the age, primary disease, menstrual history, pre-procedure chemotherapy, anti-Müllerian hormone (AMH) level, number of oocytes collected ex vivo from ovarian tissue, and number of mature oocytes from IVM were examined. RESULTS Data of 60 pediatric patients (aged 1 to 17 years) were included for analysis. Oocytes were retrieved from 36 patients; the oocytes of 18 of these patients could be cryopreserved. The IVM rate was significantly lower in the premenarchal patients than in the postmenarchal patients. The number of mature oocytes retrieved from IVM was higher in the no-chemotherapy group than in the chemotherapy group. A significant positive correlation was observed between the AMH level and the IVM outcomes. CONCLUSION Oocyte retrieval and maturation in pediatric patients undergoing OTC is particularly useful in those not receiving chemotherapy. In patients receiving chemotherapy, the AMH level may be useful for predicting the IVM outcome. Activation of the oocyte maturation process in vivo in pediatric patients and better understanding of the major regulators of oocyte maturation are necessary to improve the utility of the IVM procedure.

Developing a theory-driven framework for a web-based intervention to improve transition in childhood cancer survivors: a protocol of realist synthesis. BMJ Open 2023; 13:e074162. [PMID: 37963702 PMCID: PMC10649388 DOI: 10.1136/bmjopen-2023-074162] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Accepted: 10/29/2023] [Indexed: 11/16/2023] Open
Abstract
BACKGROUNDS AND PURPOSE Childhood cancer survivors (CCSs) who transition through adolescence and enter young adulthood may suffer psychological, cognitive, social, fertility, and sexual issues and concerns. There is an urgent need for comprehensive intervention strategies to improve the transition of CCSs. Web-based technologies are gaining momentum as a new mechanism to provide healthcare and education for adolescents. However, previous frameworks have been limited in their effectiveness in explaining web-based interventions.This realist synthesis aims to synthesise current evidence on transition of CCSs to develop a framework for web-based interventions. The framework can foster understanding of the integrity of web-based intervention implementation chain, examine which mechanistic factors will be triggered by web-based interventions, note and examine the flows, blockages and points of contention in the implementation, to refine web-based interventions. METHOD AND ANALYSIS A realist synthesis that adheres to the Realist and Meta-narrative Evidence Syntheses-Evolving Standard will be used. Studies will be identified through PubMed, Web of Science, EMBASE, PsycINFO, CINAHL, Ovid and Cochrane Library from the period of January 2005 to May 2023. We will also search the reference lists provided in relevant studies and reviews. Articles will be screened based on two principles: (1) Relevance: does the research address the initial programme theory? (2) Rigour: whether a particular inference drawn by the original researcher has sufficient weight to make a methodologically credible contribution to the test of the initial programme theory. No restrictions regarding the design or language of publication will be considered. ETHICS AND DISSEMINATION As a review, ethical approval is not required. The results from this study will be presented at international conferences and disseminated through peer-reviewed publications. Patients and the public will be involved in the dissemination plans.

Reference standards for follicular density in ovarian cortex from birth to sexual maturity. Reprod Biomed Online 2023; 47:103287.

Abstract
RESEARCH QUESTION Are age-normalized reference values for human ovarian cortical follicular density adequate for tissue quality control in fertility preservation? DESIGN Published quantitative data on the number of follicles in samples without known ovarian pathology were converted into cortical densities to create reference values. Next, a sample cohort of 126 girls (age 1-24 years, mean ± SD 11 ± 6) with cancer, severe haematological disease or Turner syndrome were used to calculate Z-scores for cortical follicular density based on the reference values. RESULTS No difference was observed between Z-scores in samples from untreated patients (0.3 ± 3.5, n = 30) and patients treated with (0.5 ± 2.9, n = 48) and without (0.1 ± 1.3, n = 6) alkylating chemotherapy. Z-scores were not correlated with increasing cumulative exposure to cytostatics. Nevertheless, Z-scores in young treated patients (0-2 years -2.1 ± 3.1, n = 10, P = 0.04) were significantly lower than Z-scores in older treated patients (11-19 years, 2 ± 1.9, n = 15). Samples from patients with Turner syndrome differed significantly from samples from untreated patients (-5.2 ± 5.1, n = 24, P = 0.003), and a Z-score of -1.7 was identified as a cut-off showing good diagnostic value for identification of patients with Turner syndrome with reduced ovarian reserve. When this cut-off was applied to other patients, analysis showed that those with indications for reduced ovarian reserve (n = 15) were significantly younger (5.9 ± 4.2 versus 10.7 ± 5.9 years, P = 0.004) and, when untreated, more often had non-malignant haematologic diseases compared with those with normal ovarian reserve (n = 24, 100% versus 19%, P = 0.009). CONCLUSION Z-scores allow the estimation of genetic- and treatment-related effects on follicular density in cortical tissue from young patients stored for fertility preservation. Understanding the quality of cryopreserved tissue facilitates its use during patient counselling. More research is needed regarding the cytostatic effects found in this study.

Preservation of Fertility in Cancer Patients: A Narrative Review. Cureus 2023; 15:e47910. [PMID: 38034134 PMCID: PMC10684029 DOI: 10.7759/cureus.47910] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2023] [Accepted: 10/29/2023] [Indexed: 12/02/2023] Open
Abstract
The survival rates for cancer patients have been steadily improving in recent years due to the improved efficacy of contemporary oncological care, including radiotherapy and chemotherapy. Modern technology makes it feasible to maintain fertility in cancer patients, and this practice needs to be included in oncological care. In many instances, it is impossible to avoid the harm that cancer treatments can cause to a patient's fertility; hence, research in fertility preservation techniques is being conducted to allow cancer patients to have future children biologically related to them. The development of fertility preservation approaches has grown in importance in the field of research over the past few years to increase patient's quality of life and survival. Oncologists must be aware of circumstances in which cancer patients' fertility will be impacted by their therapy and the avenues open for procedures like cryopreservation of the gametes or embryos. When cancer therapy is scheduled, all patients should receive prompt and thorough information on the fertility-related side effects of treatment and the prospects for fertility preservation. The article analyzes the literature, enlisting the factors that contribute to cancer and their effects on fertility, followed by a list of available and newly developed strategies for maintaining fertility in patients. The efficiency of the various fertility preservation techniques following cancer therapy is also discussed.

Abstract
STUDY QUESTION Does chemotherapy exposure affect IVM potential of immature oocytes retrieved from the ovarian cortex following ovarian tissue cryopreservation (OTC) for fertility preservation? SUMMARY ANSWER The IVM potential of oocyte retrieved from ovarian cortex following OTC is not affected by prior exposure to chemotherapy but primarily dependent on patient's age, while successful retrieval of immature oocytes from the ovarian tissue is negatively affected by chemotherapy and its timing. WHAT IS KNOWN ALREADY The potential and feasibility of IVM in premenarche patients was previously demonstrated, in smaller studies. The scarce data that exist on the IVM potential of oocytes retrieved during OTC following chemotherapy support the feasibility of this process, however, this was not previously shown in the premenarche cancer patients population or in larger cohorts. STUDY DESIGN, SIZE, DURATION A retrospective cohort study evaluating 229 cancer patients aged 1-39 years with attempted retrieval of oocytes from the ovarian tissue and the medium following OTC in a university affiliated fertility preservation unit between 2002 and 2021. PARTICIPANTS/MATERIALS, SETTING, METHODS A total of 172 chemotherapy naïve and 57 chemotherapy exposed patients aged 1-39 years underwent OTC in university affiliated tertiary infertility and IVF center. OTC and IVM outcomes were compared between the chemotherapy naïve and exposed groups. The main outcome measure was mean IVM rate per patient in the chemotherapy naïve and exposed groups, with subgroup analysis of a 1:1 chemotherapy exposed group matched for age at OTC and type of malignancy. We additionally analyzed premenarche and postmenarche patients' outcomes separately and investigated the effect of time from chemotherapy to IVM, malignancy type and chemotherapy regimen on oocyte number and IVM outcomes in the chemotherapy exposed group. MAIN RESULTS AND THE ROLE OF CHANCE While the number of retrieved oocytes and percentage of patients with at least one oocyte retrieved was higher in the chemotherapy naïve group (8.7 ± 7.9 versus 4.9 ± 5.6 oocytes and 87.2% versus 73.7%, P < 0.001 and P = 0.016, respectively), IVM rate and number of mature oocytes were comparable between the groups (29.0 ± 25.0% versus 28. 9 ± 29.2% and 2.8 ± 3.1 versus 2.2 ± 2.8, P = 0.979 and P = 0.203, respectively). Similar findings were shown in subgroup analyses for premenarche and postmenarche groups. The only parameter found to be independently associated with IVM rate in a multivariable model was menarche status (F = 8.91, P = 0.004). Logistic regression models similarly showed that past chemotherapy exposure is negatively associated with successful retrieval of oocytes while older age and menarche are predictive of successful IVM. An age and the type of malignancy matched (1:1) chemotherapy naïve and exposed groups were created (25 patients in each group). This comparison demonstrated similar IVM rate (35.4 ± 30.1% versus 31.0 ± 25.2%, P = 0.533) and number of matured oocytes (2.7 ± 3.0. versus 3.0 ± 3.9 oocytes, P = 0.772). Type of malignancy and chemotherapy regimen including alkylating agents were not associated with IVM rate. LIMITATIONS, REASONS FOR CAUTION This study's inherited retrospective design and the long study period carries the possible technological advancement and differences. The chemotherapy exposed group was relatively small and included different age groups. We could only evaluate the potential of the oocytes to reach metaphase II in vitro but not their fertilization potential or clinical outcomes. WIDER IMPLICATIONS OF THE FINDINGS IVM is feasible even after chemotherapy broadening the fertility preservation options of cancer patients. The use of IVM for fertility preservation, even after exposure to chemotherapy, should be further studied for optimal postchemotherapy timing safety and for the in vitro matured oocytes potential for fertilization. STUDY FUNDING/COMPETING INTEREST(S) No funding was received for this study by any of the authors. The authors report that no competing interests. TRIAL REGISTRATION NUMBER N/A.

Fertility Preservation in Children and Adolescents during Oncological Treatment-A Review of Healthcare System Factors and Attitudes of Patients and Their Caregivers. Cancers (Basel) 2023; 15:4393. [PMID: 37686669 PMCID: PMC10487203 DOI: 10.3390/cancers15174393] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Revised: 08/31/2023] [Accepted: 09/01/2023] [Indexed: 09/10/2023] Open
Abstract
Oncofertility is any therapeutic intervention to safeguard the fertility of cancer patients. Anti-cancer therapies (chemotherapy, radiation therapy, etc.) entail the risk of reproductive disorders through cytotoxic effects on gamete-building cells, especially those not yet fully developed. This literature review analyzes the available data on securing fertility in pediatric and adolescent populations to identify the methods used and describe aspects related to financing, ethics, and the perspective of patients and their parents. Topics related to oncofertility in this age group are relatively niche, with few peer-reviewed articles available and published studies mostly on adults. Compared to pubertal individuals, a limited number of fertility preservation methods are used for prepubertal patients. Funding for the procedures described varies from country to country, but only a few governments choose to reimburse them. Oncofertility of pediatric and adolescent patients raises many controversies related to the decision, parents' beliefs, having a partner, ethics, as well as the knowledge and experience of healthcare professionals. As the fertility of young cancer patients is at risk, healthcare professionals should make every effort to provide them with an opportunity to fulfill their future reproductive plans and to have a family and offspring. Systemic solutions should form the basis for the development of oncofertility in pediatric and adolescent populations.

Scale Validation of the Mandarin-Language Supportive Care Needs Survey-Adolescent Form. Semin Oncol Nurs 2023; 39:151442. [PMID: 37173234 DOI: 10.1016/j.soncn.2023.151442] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2022] [Revised: 03/30/2023] [Accepted: 04/12/2023] [Indexed: 05/15/2023]
Abstract
OBJECTIVES To (1) modify the Mandarin-language 34-item Supportive Care Needs Survey-Adult Form into the Adolescent Form and (2) examine the psychometric properties of the Adolescent Form. DATA SOURCES A multiphase, iterative scale validation process was used in this methodological study. Participants who were 13 to 18 years old and receiving cancer treatment in inpatient or outpatient settings, or receiving follow-up care in outpatient settings, were recruited using a convenience sampling method. Confirmatory factor analysis demonstrated good fitness of indices, and all factor loadings for the 18-item Adolescent Form were >0.50, which supported the scale's construct validity. The Adolescent Form score was significantly correlated with the symptom distress score (r = 0.56, P < .01) and quality of life score (r = -0.65, P < .01), which indicated the scale's convergent validity. The correlated item-total correlations (0.30-0.78), Cronbach's alpha (.93), and test-retest reliability coefficient (0.79) confirmed the scale's stability. CONCLUSION This study successfully modified the 34-item Adult Form into the 18-item Adolescent Form. Given its adequate psychometric properties, this concise scale has great promise as a useful, feasible, and age-appropriate tool for evaluating care needs among adolescents with cancer who speak Mandarin. IMPLICATIONS FOR NURSING PRACTICE This scale can screen for unmet care needs in busy pediatric oncology settings or large-scale clinical trials. It allows for cross-sectional comparison of unmet care needs between adolescent and adult populations and for longitudinal follow-up into how unmet care needs change from adolescence into adulthood.

Update on bioethical, medical and fertility issues in gender incongruence during transition age. J Endocrinol Invest 2023:10.1007/s40618-023-02077-5. [PMID: 37071372 PMCID: PMC10371879 DOI: 10.1007/s40618-023-02077-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2022] [Accepted: 03/22/2023] [Indexed: 04/19/2023]
Abstract
PURPOSE Many issues still remain unresolved in the management of pubertal patients with gender incongruence (GI). The aim of this review is to discuss the main aspects of the treatment of these patients to provide a practical approach for clinicians. METHODS A comprehensive literature search within PubMed was performed to provide updates of available evidence regarding the impact on bioethical, medical and fertility issues in gender incongruence during transition age. RESULTS Gender Affirming Hormone Treatment (GAHT) and Gender Affirming Surgery (GAS) can induce unsatisfaction with change, future regrets, and the risk of infertility. This raises ethical issues especially in the management of pubertal patients that remain unresolved. Therapy with GnRH analogues (GnRHa) is intended to delay puberty, so as to give the adolescent a longer period of time to decide whether to continue with the treatments. At the level of physical changes, this therapy may have an effect on bone mineralization and body composition; however, long-term longitudinal data are not yet available. An important feature related to the use of GnRHa is the risk of fertility. Gamete cryopreservation is the most established method of fertility preservation (FP) and should be counselled to transgender adolescents. However, these patients are not always interested in having biological children. CONCLUSION Based on the current evidence, there is a need to conduct further research to clarify certain issues and to standardize clinical practice and improve counselling in transgender adolescent decision making and avoid regrets in the future.

Survey of understanding and awareness of fertility preservation in pediatric patients: Is conversation about fertility preservation unpleasant for pediatric patients? Front Endocrinol (Lausanne) 2023; 13:1074603. [PMID: 36686445 PMCID: PMC9853553 DOI: 10.3389/fendo.2022.1074603] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2022] [Accepted: 12/05/2022] [Indexed: 01/07/2023] Open
Abstract
Objective To verify understanding and awareness of fertility preservation (FP) in pediatric patients undergoing FP treatments. Methods A questionnaire survey was conducted before and after explanation of fertility issues and FP treatments for patients 6-17 years old who visited or were hospitalized for the purpose of ovarian tissue cryopreservation (OTC) or oocyte cryopreservation (OC), or sperm cryopreservation between October 2018 and April 2022. This study was approved by the institutional review board at St. Marianna University School of Medicine (No. 4123, UMIN000046125). Result Participants in the study comprised 36 children (34 girls, 2 boys). Overall mean age was 13.3 ± 3.0 years. The underlying diseases were diverse, with leukemia in 14 patients (38.9%), brain tumor in 4 patients (11.1%). The questionnaire survey before the explanation showed that 19 patients (52.8%) wanted to have children in the future, but 15 (41.7%) were unsure of future wishes to raise children. And most children expressed some degree of understanding of the treatment being planned for the underlying disease (34, 94.4%). Similarly, most children understood that the treatment would affect their fertility (33, 91.7%). When asked if they would like to hear a story about how to become a mother or father after FP which including information of FP, half answered "Don't mind" (18, 50.0%). After being provided with information about FP treatment, all participants answered that they understood the adverse effects on fertility of treatments for the underlying disease. Regarding FP treatment, 32 children (88.9%) expressed understanding for FP and 26 (72.2%) wished to receive FP. "Fear" and "Pain" and "Costs" were frequently cited as concerns about FP. Following explanations, 33 children (91.7%) answered "Happy I heard the story" and no children answered, "Wish I hadn't heard the story". Finally, 28 of the 34 girls (82.4%) underwent OTC and one girl underwent OC. Discussion The fact that all patients responded positively to the explanations of FP treatment is very informative. This is considered largely attributable to the patients themselves being involved in the decision-making process for FP. Conclusions Explanations of FP for children appear valid if age-appropriate explanations are provided.

Abstract
Fertility navigators (FNs) are important in communicating infertility risk and fertility preservation (FP) options to patients receiving gonadotoxic therapies. This retrospective study examined electronic medical records of patients with fertility consults at a large pediatric institution (2017-2019), before and after hiring a full-time FN. Of 738 patient encounters, 173 consults were performed pre-navigator and 565 post-navigator. Fertility consults for long-term follow-up cancer survivors increased most substantially: pre-navigator (n = 7) and post-navigator (n = 387). Across diagnoses, females had a larger increase in consults compared to males (χ2 [3, N = 738] = 8.17, p < .05). Findings highlight FNs' impact on counseling rates, particularly in survivorship.

Sexual and fertility-related adverse effects of medicinal treatment for cancer; a national evaluation among medical oncologists. Support Care Cancer 2022; 30:4035-4047. [PMID: 35064326 DOI: 10.1007/s00520-021-06721-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2021] [Accepted: 11/22/2021] [Indexed: 10/19/2022]
Abstract
BACKGROUND Anti-cancer drugs commonly adversely affect fertility and sexual function. Despite this, patients report a lack of counselling of these potential adverse effects. The aim was to determine Dutch oncologists' knowledge about the adverse effects of various cancer drugs on fertility and sexual function. METHODS A cross-sectional survey was sent to members of the Dutch Society for Medical Oncology (n = 433). The survey questions included various cancer drugs' adverse effects on fertility, ovulation, spermatogenesis, and sexual function. RESULTS One hundred and five of 392 oncologists responded (26.8%). Oncologists were more aware of the adverse effects on fertility compared to sexual function. Drugs that were mostly believed to negatively affect fertility were cisplatin (n = 81, 80.2%), epirubicin (n = 78, 78.0%) and cyclophosphamide (n = 80, 77.7%). Regarding sexual function, most mentioned drugs were tamoxifen (n = 67, 65.7%), GnRH-agonists (n = 64, 63.4%) and cisplatin (n = 58, 57.4%). Oncologists with expertise in urology possessed more awareness regarding sexuality-related adverse effects (cisplatin p = 0.038, etoposide p = 0.025, ifosfamide p = 0.06, vinblastine p = 0.000). CONCLUSION Results revealed that oncologists have different beliefs about possible sexual and fertility-related adverse effects concerning medication resources and literature. Based on our results, oncologists do not possess sufficient knowledge to inform patients about sexual and fertility-related adverse effects.

Abstract
Background Cryopreservation of ovarian tissue is a fertility-preservation option for women before gonadotoxic treatments. However, cryopreserved ovarian tissue transplantation must be performed with caution in women with malignancies that may metastasize to the ovaries. For this purpose, detecting minimal residual disease (MRD) in the ovarian cortex using sensitive methods is a crucial step. We developed an automated ovarian tissue dissociation method to obtain ovarian cell suspensions. Results We assessed MRD by multicolor flow cytometry (MFC) in cryopreserved ovarian cortex of 15 leukemia patients: 6 with B-cell acute lymphoblastic leukemia (B-ALL), 2 with T-cell acute lymphoblastic leukemia (T-ALL) and 7 with acute myeloid leukemia (AML). Ovarian MRD was positive in 5 of the 15 leukemia patients (one T-ALL and 4 AML). No B-ALL patient was positive by MFC. Quantitative reverse-transcribed polymerase chain reaction was performed when a molecular marker was available, and confirmed the MFC results for 3 patients tested. Xenografts into immunodeficient mice were also performed with ovarian cortical tissue from 10 leukemia patients, with no evidence of leukemic cells after the 6-month grafting period. Conclusions In conclusion, this is the first study using MFC to detect MRD in ovarian cortical tissue from acute leukemia patients. MFC has been accepted in clinical practice for its ease of use, the large number of parameters available simultaneously, and high throughput analysis. We demonstrate here that MFC is a reliable method to detect MRD in cryopreserved ovarian tissue, with a view to controlling the oncological risk before ovarian tissue transplantation in leukemia patients.

Abstract
Counseling children on the possibility of fertility preservation prior to a gonadotoxic treatment supports the decision-making process, taking into account that the patients are in a very vulnerable and mentally exhausting situation following the diagnosis. Referral to specialists can be optimized on-site by routing slips with contact addresses, phone numbers, and mail contacts; available time slots for consultation; possibly offers for cost coverage; and an easy-to-understand information leaflet about the different options available. Some of the options for fertility preservation in the prepubertal population especially are still experimental. The unique possibility of fertility preservation before the onset of the gonadotoxic therapy, which may cause premature ovarian insufficiency or azoospermia in the future, should be highlighted.

Fertility preservation for pediatric patients with hemoglobinopathies: Multidisciplinary counseling needed to optimize outcomes. Front Endocrinol (Lausanne) 2022; 13:985525. [PMID: 36353243 PMCID: PMC9638952 DOI: 10.3389/fendo.2022.985525] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Accepted: 09/30/2022] [Indexed: 01/19/2023] Open
Abstract
Hemoglobinopathies are autosomal recessive disorders that occur when genetic mutations negatively impact the function of hemoglobin. Common hemoglobinopathies that are clinically significant include sickle cell disease, alpha thalassemia, and beta thalassemia. Advancements in disease-modifying and curative treatments for the common hemoglobinopathies over the past thirty years have led to improvements in patient quality of life and longevity for those who are affected. However, the diseases, their treatments and cures pose infertility risks, making fertility preservation counseling and treatment an important part of the contemporary comprehensive patient care. Sickle cell disease negatively impacts both male and female infertility, primarily by testicular failure and decreased ovarian reserve, respectively. Fertility in both males and females with beta thalassemia major are negatively impacted by iron deposition due to chronic blood transfusions. Hematopoietic stem cell transplant (HSCT) is currently the only curative treatment for SCD and transfusion dependent beta thalassemia. Many of the conditioning regimens for HSCT contain chemotherapeutic agents with known gonadotoxicity and whole-body radiation. Although most clinical studies on toxicity and impact of HSCT on long-term health do not evaluate fertility, gonadal failure is common. Male fertility preservation modalities that exist prior to gonadotoxic treatment include sperm banking for pubertal males and testicular cryopreservation for pre-pubertal boys. For female patients, fertility preservation options include oocyte cryopreservation and ovarian tissue cryopreservation. Oocyte cryopreservation requires controlled ovarian hyperstimulation (COH) with ten to fourteen days of intensive monitoring and medication administration. This is feasible once the patient has undergone menarche. Follicular growth is monitored via transvaginal or transabdominal ultrasound, and hormone levels are monitored through frequent blood work. Oocytes are then harvested via a minimally invasive approach under anesthesia. Complications of COH are more common in patients with hemoglobinopathies. Ovarian hyperstimulation syndrome creates a greater risk to patients with underlying vascular, pulmonary, and renal injury, as they may be less able to tolerate fluids shifts. Thus, it is critical to monitor patients undergoing COH closely with close collaboration between the hematology team and the reproductive endocrinology team. Counseling patients and families about future fertility must take into consideration the patient's disease, treatment history, and planned treatment, acknowledging current knowledge gaps.

Abstract
INTRODUCTION Childhood cancer is rare; the incidence in Sweden is approximately 16 new cases/100 000 children each year. Reduced reproductive function and fertility are well-known side effects of cancer treatment. Anti-Müllerian hormone (AMH) has been shown to correlate well with antral follicle count in healthy women but is currently not recommended as the primary surveillance modality for evaluation of premature ovarian insufficiency in this patient group. Psychological wellbeing related to fertility could affect quality of life and should be included in long-term follow-up. The aim of the study is to present the baseline data from inclusion for a prospective follow-up study of fertility surveillance where both medical and psychological aspects of fertility in female childhood cancer survivors are considered. MATERIAL AND METHODS These are the first results from this longitudinal follow-up cohort study. Female adolescent and young adult survivors of pediatric cancer in Western Sweden were included from January 2016 to December 2018, a total of 54 participants. Median age at inclusion was 21 (15-29) years and median age at cancer diagnosis was 10 (1-17) years. AMH levels, antral follicle count, and data on fertility were recorded at inclusion and will be prospectively followed up. The study includes questionnaires and interviews concerning quality of life. This study is planned to continue until the participants reach the age of 40 years. RESULTS Eighteen of 54 (33%) participants had AMH levels below 1.0 µg/L and were considered to have high or very high risk of infertility. Median AMH level was 2.50 µg/L. Six women had immediate need of oocyte cryopreservation. Psychological assessment showed that more than one-third of participants (n = 20) had elevated anxiety scores. CONCLUSIONS One-third of female survivors of pediatric cancer in the study had high risk of low ovarian reserve, measured by a combination of AMH and antral follicle count, and many had signs of anxiety. The longitudinal study could contribute to better knowledge in the changes of AMH over time for this patient group. Psychological follow-up with questionnaires and interviews evaluating signs of depression and anxiety may serve as a model for future screening programs.

Abstract
Adolescence is a period of flux for many body systems. While fertility potential typically increases after menarche, there are diseases where the opposite occurs and fertility preservation options need to be considered early. In cases of cancer, options vary by pubertal status and can include ovarian tissue cryopreservation, oocyte cryopreservation, sperm cryopreservation, and testicular tissue cryopreservation. Much remains to be learned about fertility and preservation options in those with differences in sexual development (DSDs); however, depending on the form of DSD, fertility preservation may not be necessary. Similarly, traditional fertility counseling in children with galactosemia may need to be changed, as data suggest that fertility rates attributed to other causes of premature ovarian insufficiency may not be as applicable to this disease. Adolescents with Turner's syndrome are at high risk for premature ovarian failure; therefore, it is important to consider options as early as possible since ovarian reserves are depleted quickly. On the other hand, transgender and gender diverse adolescents may even be able to undergo fertility preservation after starting hormone therapy. In all cases, there are additional ethical components including technical/surgical risks in childhood, offering experimental therapies without creating false hope and evaluating children's consent and assent capabilities that must be considered.

Abstract
PURPOSE Fertility preservation (FP) for children is still challenging due to an information gap. In particular, there is little information about the surgical aspects of ovarian tissue cryopreservation (OTC) for children. In the present study, the appropriateness of preoperative management and the criteria of our cases were investigated with the aim of establishing a safe OTC procedure. METHODS A total of 25 girls who underwent OTC from November 2015 through May 2020 were retrospectively analyzed with IRB approval. RESULTS The median age of the patients was 13 (1-17) years. The medical indications were varied (e.g., leukemia, lymphoma, brain tumor), and included rare diseases. Seventeen cases (68%) underwent OTC during chemotherapy or radiotherapy, and 21 (84%) had comorbidities. All cases underwent ovarian tissue retrieval (OTR) with laparoscopy, and the median operating time was 64 (36-97) min, with little bleeding. Although two had complications, all patients started treatment on schedule. The median WBC and CRP increases a day after OTR were 0 (- 4400 to + 5200)/µl and 0.21 (- 0.2 to 0.87) mg/dl, respectively, with no complications. CONCLUSION As long as the preoperative criteria are met, OTC could be possible even for children with a severe blood condition. In such cases, the degrees of the WBC and CRP elevations are useful to assess surgical infection.

Abstract
Simple Summary Fertility impairment is common among male childhood cancer survivors and negatively impacts quality of life. Sperm banking, before starting cancer treatment, is an established fertility preservation option, yet it remains underutilized at many pediatric centers. Although survivors often report regret about missed banking opportunities, little is known about short-term decisional satisfaction. The aim of this mixed methods study was to examine decisional satisfaction one month after diagnosis by comparing satisfaction among families of adolescents who did or did not attempt to bank. Quantitatively, families reported satisfaction regardless of the banking decision, while qualitatively, families of adolescents who did not attempt to bank reported potential for future regret. Thus, decisional dissatisfaction may not present after one month but could emerge in the future. The findings underscore the importance of longitudinal research to examine satisfaction over time, and why quantitative and qualitative discrepancies exist, as well as psychosocial support across the care continuum as survivors approach their reproductive years. Abstract Half of male childhood cancer survivors experience treatment-related fertility impairment, which can lead to distress. Survivors often regret forgoing fertility preservation (FP), and decisional dissatisfaction is associated with a lower quality of life. This mixed methods study examined short-term FP decisional satisfaction among families of male adolescents newly diagnosed with cancer who received an initial fertility consult and completed an FP values clarification tool. One-two months after the FP decision, thirty-nine families completed the Brief Subjective Decision Quality measure. Decisional satisfaction was compared for participants (mothers, fathers, adolescents) who did and did not attempt to bank. Semi-structured interviews included the following question: How do you/your family feel about the banking decision now/in the future? Decisional quality scores were moderate-high (M = 5.74–6.33 out of 7), with no significant differences between non-attempter (n = 15) and attempter (n = 24) families (adolescents: p = 0.83, d = 0.08; mothers: p = 0.18, d = 0.45; fathers: p = 0.32, d = 0.44). Three qualitative themes emerged among non-attempter families: (1) satisfaction with decision (50% of participants), (2) acceptance of decision (60%), and (3) potential for future regret (40%). Satisfaction with decision was the only theme identified in attempter families (93%). Quantitively, short-term decisional satisfaction was high regardless of the banking attempt. However, the qualitative findings suggest that the experiences of families who did not bank may be more nuanced, as several participants discussed a potential for future regret, highlighting the importance of ongoing support.

Abstract
STUDY QUESTION How do women, who have just been diagnosed with breast cancer, experience oocyte or embryo banking? SUMMARY ANSWER Fertility preservation was a challenging yet welcome way to take action when confronted with breast cancer. WHAT IS KNOWN ALREADY Fertility preservation for women with breast cancer is a way to safeguard future chances of having children. Women who have just been diagnosed with breast cancer report stress, as do women who have to undergo IVF treatment. How women experience the collision of these two stressfull events, has not yet been studied. STUDY DESIGN, SIZE, DURATION We performed a multicenter qualitative study with a phenomenological approach including 21 women between March and July 2014. Women were recruited from two university-based fertility clinics. PARTICIPANTS/MATERIALS, SETTING, METHODS Women with breast cancer who banked oocytes or embryos 1–15 months before study participation were eligible. We conducted in-depth, face-to-face interviews with 21 women, which was sufficient to reach data saturation. MAIN RESULTS AND THE ROLE OF CHANCE The 21 women interviewed had a mean age of 32 years. Analysis of the 21 interviews revealed three main experiences: the burden of fertility preservation, the new identity of a fertility patient and coping with breast cancer through fertility preservation. LIMITATIONS, REASONS FOR CAUTION Interviewing women after, rather than during, fertility preservation might have induced recall bias. Translation of quotes was not carried out by a certified translator. WIDER IMPLICATIONS OF THE FINDINGS The insights gained from this study of the experiences of women undergoing fertility preservation while being newly diagnosed with breast cancer could be used as a starting point for adapting the routine psychosocial care provided by fertility clinic staff. Future studies are necessary to investigate whether adapting routine psychosocial care improves women’s wellbeing. STUDY FUNDING/COMPETING INTEREST(S) None of the authors in this study declare potential conflicts of interest. The study was funded by the Center of Reproductive Medicine of the Academic Medical Center.

Abstract
Fertility preservation represents one important goal of cancer patients’ management due to the high impact on health and quality of life of survivors. The available preventive measures cannot be performed in all patients and are not feasible in all health-care facilities. Therefore, the pharmacological treatment with GnRHa has become a valuable non-invasive and well-tolerated alternative, especially in those who cannot access to cryopreservation options due to clinical and/or logistic issues. Supporting data demonstrate a significant advantage for the survivors who received GnRHa in the long-term maintenance of ovarian function and preservation of fertility. The prevention of the risk of ovarian failure with GnRHa is a typical off-label use, defined as the administration of a medicinal product not in accordance with the authorized product information. Italy has officially recognized the off-label use of GnRHa in adult women at risk of premature and permanent menopause following chemotherapy. However, fertility preservation still represents an unmet medical need in adolescents who cannot access to other treatment options.

Abstract
Rhabdomyosarcoma is the commonest soft tissue sarcoma in children. Clinicians need vigilance to recognize the different signs and symptoms this tumor can present with because of variable sites of origin. Diagnosis requires a safe biopsy that obtains sufficient tissue for pathologic, genetic, and biological characterization of the tumor. Treatment depends on accurate staging with imaging and surgical sampling of draining lymph nodes. A multidisciplinary team assigns patients to risk-based therapy. Patients require chemotherapy and usually a combination of complex, site-specific surgery and/or radiotherapy. Outcomes for localized rhabdomyosarcoma continue to improve but new treatments are required for metastatic and relapsed disease.

Abstract
We review the history, current status, and potential future of state infertility mandates and focus on the business implications of mandates and on the inadequacies and reproductive injustice resulting from gaps between legislative intent and practical implementation. Nineteen states have passed laws that require insurers to either cover or offer coverage for infertility diagnoses and treatment. The qualifications for coverage, extent of coverage, and exemptions vary drastically from one state to another, resulting in deficiencies in access to care even within mandated states for certain groups, such as single individuals, patients in same-sex relationships, and patients pursuing fertility preservation. Although insurance coverage of fertility services in the United States has expanded as an increasing number of states have enacted infertility mandates, significant gaps in implementation and access remain even among states with existing mandates. Provider, patient, and legislative advocacy is warranted in the name of reproductive justice to expand insurance coverage and, in turn, maximize reproductive outcomes, which have been shown to improve as financial barriers are lifted.

Abstract
Refinement of therapies continues to improve the prognosis and survival of cancer patients. However, women of reproductive age face a risk of premature ovarian failure due to the gonadotoxicity of aggressive oncological treatment, which may also be used to treat other nonmalignant disorders. Development of cryobiology and assisted reproduction has allowed fertility preservation, which is increasingly requested, and can also aid fertility in iatrogenic and noniatrogenic conditions. Established protocols including embryo and oocyte freezing are only performed for adult women; however, ovarian tissue cryopreservation is an approach that can also assist prepubertal girls. Medical fertility cryopreservation for females has been recently legalized in Saudi Arabia. However, prior to implementing the service in clinical practice in Saudi Arabia, guidelines on patient selection criteria and adequate staff training are essential. Moreover, worldwide registry data and the findings of long-term studies involving many patients on the safety of ovarian tissue freezing are required to conclusively establish medical fertility cryopreservation as a safe procedure. Progress can be achieved in oncofertility by improving and optimizing techniques that include immature oocyte growth and maturation and artificial ovary development.

Abstract
Background and objectives: Cancer incidence is growing with younger patients diagnosed with this disease every year. Improved cancer diagnostics and treatment lead to better survival of cancer patients. However, after aggressive chemo- or radiotherapy, cancer survivors suffer from various degrees of subfertility or infertility. Several fertility preservation technologies have been developed for young cancer patients: cryopreservation of germ cells, embryos, or reproductive tissues. The best results have been shown by cryopreservation of sperm and embryos. Yet the success of using cryopreserved oocytes or reproductive tissues (ovarian and testicular) is still insufficient. Therefore, this study was designed to assess the vitality, viability, general quality, and safety of frozen-thawed human ovarian tissue for retransplantation using modern molecular tests. Materials and Methods: The new miRNA array test was used to evaluate miRNA expression in thawed ovarian tissue in combination with standard xenotransplantation and pathological examination of microslides. Results: Our results demonstrated that slow freezing is an efficient way (80%) to cryopreserve ovarian tissue with no structural damage afterwards. We have shown that xenotransplantation into immunodeficient mice, histology, and immunohistochemistry could be potentially replaced by more recent molecular methods. Conclusions: The latter method has shown that altered expression of miRNAs might be used as identifiers of normal/damaged tissue after further analysis. Newer, safer, and more specific approaches need to be developed in order to eliminate the risk of disease reoccurrence.

Abstract
(1) Background: Ovarian tissue transplantation with adipose tissue-derived stem cells (ASCs) has been shown to enhance graft vascularization and increase follicle survival after a short interval of 7 days. The aim of the present study was to investigate their long-term effects on primordial follicle pool maintenance and follicle development. (2) Methods: A total of 14 severe combined immunodeficient (SCID) mice were grafted with frozen-thawed human ovarian tissue with or without ASCs. Blood was taken monthly in order to quantify the anti-Müllerian hormone (AMH) and estradiol. After 6 months, all the grafts were retrieved and sent for histology and immunolabeling (AMH, AMH receptor II, estrogen receptors α and β, and c-kit/kit ligand). (3) Results: A significant upturn was observed in AMH and estradiol plasma levels 4 months after transplantation in both grafted groups. The primordial follicle pool was better preserved in the ASC group (41.86 ± 28.35) than in the standard transplantation group (9.65 ± 17.6, p < 0.05) compared to non-grafted controls (124.7 ± 140). (4) Conclusions: The use of ASCs prior to ovarian tissue transplantation yielded a larger primordial follicle pool and more physiological follicle distribution after long-term grafting. These findings suggested that ASC use might extend the ovarian tissue lifespan.

Abstract
In reproductive medicine, the technique of rapid cooling becomes increasingly important for the preservation of tissue and cells. In order to protect the cells, incubation in different cryopreservation solutions is essential. The speed of the cooling process also makes a pivotal contribution to the success of this method. Using Flourescence Activated Cell Sorting (FACS), we investigated the impact of an open rapid and a closed rapid cooling technique on the vitality of human granulosa cells. Furthermore, we examined effects of the different solutions used for rapid cooling and warming before and after rapid cooling. We found a significant lower proportion of vital cells after rapid cooling compared to untreated controls independently of the technique and the tube size. However, we did not find any significant differences between open and closed rapid cooling. In both, a lower proportion of vital granulosa cells were found after incubation in rapid cooling solution only compared to warming solution only. Our results lend support to the conclusion that the difference of cooling-speed between open and closed rapid cooling is, in our settings, not crucial for the success of the procedure and that cryoprotective agents in the rapid cooling solutions have a higher potential to cause severe cell damage than agents used for warming.

Abstract
Ovarian tissue cryopreservation has recently been performed as an option for fertility preservation in prepubertal girls with cancer. In this study, ovarian tissue was cryopreserved from 3 girls of 3 years of age or younger during a 3-year period at our institution. Case 1 was a 1-year-old girl, who was diagnosed with a yolk sac tumor in the sacral region. Case 2 was a 2-year-old girl, who was diagnosed with retroperitoneal neuroblastoma. Case 3 was a 3-year-old girl, who was diagnosed with cerebellar medulloblastoma. All patients had planned to undergo chemotherapy that would affect the ovarian reserve. Because these patients were toddlers, consideration of ethics, the surgical procedure and postoperative management, and optimal method for freezing ovarian tissue was necessary, although gynecologists rarely experience these challenges in daily clinical practice. We herein present the clinical course of these three cases and discuss the peculiarities and countermeasures of ovarian cryopreservation in children.

Abstract
Since the birth of the first child conceived via in vitro fertilization 40 years ago, fertility treatments and assisted reproductive technology have allowed many couples to reach their reproductive goals. As of yet, no fertility options are available for men who cannot produce functional sperm, but many experimental therapies have demonstrated promising results in animal models. Both autologous (stem cell transplantation, de novo morphogenesis, and testicular tissue grafting) and outside-the-body (xenografting and in vitro spermatogenesis) approaches exist for restoring sperm production in infertile animals with varying degrees of success. Once safety profiles are established and an ideal patient population is chosen, some of these techniques may be ready for human experimentation in the near future, with likely clinical implementation within the next decade.

Abstract
BACKGROUND Fertility preservation (FP) is an important quality of life issue for cancer survivors of reproductive age. Despite the existence of broad international guidelines, the delivery of oncofertility care, particularly amongst paediatric, adolescent and young adult patients, remains a challenge for healthcare professionals (HCPs). The quality of oncofertility care is variable and the uptake and utilization of FP remains low. Available guidelines fall short in providing adequate detail on how oncofertility models of care (MOC) allow for the real-world application of guidelines by HCPs. OBJECTIVE AND RATIONALE The aim of this study was to systematically review the literature on the components of oncofertility care as defined by patient and clinician representatives, and identify the barriers, facilitators and challenges, so as to improve the implementation of oncofertility services. SEARCH METHODS A systematic scoping review was conducted on oncofertility MOC literature published in English between 2007 and 2016, relating to 10 domains of care identified through consumer research: communication, oncofertility decision aids, age-appropriate care, referral pathways, documentation, training, supportive care during treatment, reproductive care after cancer treatment, psychosocial support and ethical practice of oncofertility care. A wide range of electronic databases (CINAHL, Embase, PsycINFO, PubMed, AEIPT, Education Research Complete, ProQuest and VOCED) were searched in order to synthesize the evidence around delivery of oncofertility care. Related citations and reference lists were searched. The review was undertaken following registration (International prospective register of systematic reviews (PROSPERO) registration number CRD42017055837) and guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). OUTCOMES A total of 846 potentially relevant studies were identified after the removal of duplicates. All titles and abstracts were screened by a single reviewer and the final 147 papers were screened by two reviewers. Ten papers on established MOC were identified amongst the included papers. Data were extracted from each paper and quality scores were then summarized in the oncofertility MOC summary matrix. The results identified a number of themes for improving MOC in each domain, which included: the importance of patients receiving communication that is of a higher quality and in different formats on their fertility risk and FP options; improving provision of oncofertility care in a timely manner; improving access to age-appropriate care; defining the role and scope of practice of all HCPs; and improving communication between different HCPs. Different forms of decision aids were found useful for assisting patients to understand FP options and weigh up choices. WIDER IMPLICATIONS This analysis identifies core components for delivery of oncofertility MOC. The provision of oncofertility services requires planning to ensure services have safe and reliable referral pathways and that they are age-appropriate and include medical and psychological oncofertility care into the survivorship period. In order for this to happen, collaboration needs to occur between clinicians, allied HCPs and executives within paediatric and adult hospitals, as well as fertility clinics across both public and private services. Training of both cancer and non-cancer HCPs is needed to improve the knowledge of HCPs, the quality of care provided and the confidence of HCPs with these consultations.

Fertility Preservation for Child and Adolescent Cancer Patients in Asian Countries. Front Endocrinol (Lausanne) 2019; 10:655.

Abstract
Background: At present, fertility is one of the main concerns of young cancer patients. Following this trend, "fertility preservation (FP)" has been established and has become a new field of reproductive medicine. However, FP for child and adolescent (C-A) cancer patients is still developing, even in advanced countries. The aim of the present study was to assess the barriers to FP for C-A patients by investigating the current status of FP for C-A patients in Asian countries, which just have started FP activities. Method: A questionnaire survey of founding members of the Asian Society for Fertility Preservation (ASFP) was conducted in November 2018. Main findings: Of the 14 countries, 11 country representatives replied to this survey. FP for C-A patients is still developing in Asian countries, even in Australia, Japan, and Korea, which have organizations or academic societies specialized for FP. In all countries that replied to the present survey, the patients can receive embryo cryopreservation (EC), oocyte cryopreservation (OC), and sperm cryopreservation (SC) as FP. Compared with ovarian tissue cryopreservation (OTC), testicular tissue cryopreservation (TTC) is an uncommon FP treatment because of its still extremely experimental status (7 of 11 countries provide it). Most Asian countries can provide FP for C-A patients in terms of medical technology, but most have factors inhibiting to promote FP for C-A patients, due to lack of sufficient experience and an established system promoting FP for C-A patients. "Don't know how to provide FP treatment for C-A" is a major barrier. Also, low recognition in society and among medical staff is still a particularly major issue. There is also a problem with cooperative frameworks with pediatric departments. To achieve high-quality FP for C-A patients, a multidisciplinary approach is vital, but, according to the present study, few paramedical staff can participate in FP for C-A patients in Asia. Only Australia and Korea provide FP information by video and specific resources. Conclusion: The present study demonstrated the developing status of FP for C-A patients in Asian countries. More intensive consideration and discussion are needed to provide FP in Asian societies based on the local cultural and religious needs of patients.

Abstract
INTRODUCTION While many childhood cancers are curable with therapy, adverse consequences in fertility exist. We sought to assess the number of female patients with pelvic tumors receiving radiation therapy, and the proportion that undergo measures for fertility preservation (FP). METHODS A total of 53 female patients treated with pelvic tumors from 2000 to 2016 were retrospectively identified. RESULTS 19 (34%) of these patients underwent pelvic radiation therapy (pXRT). Three of the patients received pXRT for palliative treatment. Of the 19 female patients receiving pXRT, six (31%) were prepubertal and 13 (68%) were postpubertal. Three patients (16%) had documentation of a discussion of FP measures prior to pXRT. One was prepubertal and the others were post-pubertal. Six patients (32%) were evaluated by endocrinology after radiation therapy, diagnosed with ovarian failure, and placed on hormone therapy. Current guidelines recommend discussion of FP in pre-and postpubertal patients with cancer. This 16-year retrospective review of female patients that underwent pXRT for pelvic tumors demonstrated < 17% of patients have documentation of a discussion of FP measures. CONCLUSION Female pediatric patients who underwent chemotherapy and pXRT suffer a high rate of premature ovarian failure, high morbidity and mortality as well as low rates of documented FP discussions. Based on these findings we have established a multi-disciplinary fertility preservation team available for consultation and a protocol for discussing and documenting the impact of pXRT, along with other treatments, on fertility.

Abstract
As the 5-year survival rate increases up to 80% in pediatric cancer patients, the number of women patients with reduced gonadal function by chemotherapy and radiotherapy increases. The gonadal toxicity of pediatric patients varies highly according to the chemotherapeutic agent and the type of radiotherapy. Although American Society of Clinical Oncology published the guideline for fertility preservation, additional scientific and ethical concerns should be considered for clinical practice. In addition, only the experimental method can be applied for the prepubertal patients in contrast to the postpubertal patients. In this review, we will discuss some options for preserving fertility among women's quality of life issues.
