RESUMO

International and national oncofertility networks, including the US-led Oncofertility Consortium, FertiProtekt, and the Danish Network, have played pivotal roles in advancing the discipline of oncofertility over the last decade. Many other countries lack a shared approach to pediatric oncofertility health service delivery. This study aims to describe baseline oncofertility practices at Australian New Zealand Children's Haematology/Oncology Group centers in 2019-2021, describe binational priorities for care, and propose a 5-year action plan for best practice to be implemented by the newly formed Australian New Zealand Consortium in Children, Adolescents, and Young Adults (CAYA) Oncofertility (ANZCO).

RESUMO

RESEARCH QUESTION: Is there potential for the detection of neuroblastoma malignancy in testicular tissue extracted for fertility preservation for prepubertal boys at the time of tissue freezing? DESIGN: This is a case report. RESULTS: A boy was diagnosed with primary localized left adrenal neuroblastoma, with complete resection of the tumour. During 6 months' surveillance, he developed a relapse in the left para-renal region with progression of molecular and chromosomal features into undifferentiated neuroblastoma. Before highly gonadotoxic treatment, testicular biopsy for fertility preservation was taken, from a clinically normal testis. Histopathological examination of the testicular biopsy revealed metastatic neuroblastoma. CONCLUSIONS: Metastatic neuroblastoma detected histologically in a clinically normal testis highlights the importance of routine histological examination at the time of testicular cryopreservation. The histological evaluation of gonadal tissue for potential malignant contamination before freezing should be mandatory, regardless of the malignancy diagnosis. Advances in sensitive molecular detection and in-vitro maturation are critically required to decrease future risk of disease recurrence in both solid and haematological malignancies.

RESUMO

Tumors of the breast and reproductive organs that occur in children, adolescents, and young adults (AYA) have different biological features and can present special challenges. Although prognosis for these tumors is generally favorable, the long-term effects of treatment can be debilitating. Treatments are often multimodal and may include surgery as well as chemotherapy and/or radiation, which can cause considerable distress and anxiety related to loss of femininity or masculinity, concern over future fertility, or sexual dysfunction. Thus, tumors of the reproductive organs in pediatric/AYA patients require special consideration of the treatment effects beyond the intended oncologic outcome. Multidisciplinary teams should be involved in their care and address issues of fertility, sexual dysfunction, and psychosexual concerns before treatment begins. This review addresses histology, risk factors, prognosis, staging and treatment of gynecologic, breast and testicular cancers in pediatric and AYA patients.

RESUMO

An estimated 500,000 cancer survivors of reproductive age in the United States will live to experience the long-term consequences of cancer treatment. Therefore, a focused aspect of cancer care has appropriately shifted to include quality of life in survivorship. Infertility is a late effect of therapy that affects 12% of female survivors of childhood cancer receiving any cancer treatment in large cohort studies and results in a 40% decreased likelihood of pregnancy in young adults of ages 18-39 years. Nonfertility gynecologic late effects such as hypoestrogenism, radiation-induced uterine and vaginal injury, genital graft-versus-host disease after hematopoietic stem cell transplant, and sexual dysfunction also significantly affect quality of life in survivorship but are underdiagnosed and require consideration. Several articles in the special edition "Reproductive Health in Adolescent and Young Adult Cancer Survivorship" address infertility, genital graft-versus-host disease, and psychosexual functioning in survivorship. This review article focuses on other adverse gynecologic outcomes of cancer therapies including hypogonadism and hormone replacement therapy, radiation-induced uterovaginal injury, vaccination and contraception, breast and cervical cancer screening, and pregnancy considerations in survivorship.

RESUMO

PURPOSE: Increasing numbers of transgender adolescents are receiving gender-affirming treatments (GAT). Given GAT can impair reproductive function, clinical guidelines advise prior counselling regarding fertility preservation (FP). For transgender adults assigned male at birth, FP is usually achieved via a masturbatory sample and sperm cryopreservation. This is less straightforward in transgender adolescents, since they may not be developmentally ready to masturbate and/or masturbation may cause unacceptable gender dysphoria. Testicular biopsy represents an alternative method for sperm retrieval in these adolescents, but for those in early/mid puberty, it is difficult to predict whether sperm will be found. The purpose of this study was therefore to identify factors that predict successful sperm retrieval for cryopreservation via testicular biopsy. METHODS: A retrospective cohort study was undertaken at a tertiary-referral pediatric gender service. Subjects were included if they'd received a testicular biopsy in association with the commencement of GAT between 2010 and 2019. The primary outcome measure was successful sperm retrieval, and potential predictors included age, testicular volume and serum testosterone, LH and FSH levels. RESULTS: Of 25 subjects who received a biopsy prior to starting any GAT, 17 had successful sperm retrieval. While age, testosterone, LH and FSH levels showed minimal differences, testicular volume was significantly higher in those with successful sperm retrieval, and a threshold of ≥ 10 mL showed 92% sensitivity and 71% specificity in predicting successful retrieval. An additional 6 patients received a biopsy after starting puberty suppression and before commencement of oestrogen, and one of these individuals had sperm successfully retrieved despite > 2 years of regular puberty suppression. CONCLUSION: These findings suggest that testicular volume is most useful in predicting successful sperm retrieval following testicular biopsy in transgender adolescents and are likely to be of relevance to other young people undertaking FP, including those with cancer.

RESUMO

PURPOSE: Today, male and female adult and pediatric cancer patients, individuals transitioning between gender identities, and other individuals facing health extending but fertility limiting treatments can look forward to a fertile future. This is, in part, due to the work of members associated with the Oncofertility Consortium. METHODS: The Oncofertility Consortium is an international, interdisciplinary initiative originally designed to explore the urgent unmet need associated with the reproductive future of cancer survivors. As the strategies for fertility management were invented, developed or applied, the individuals for who the program offered hope, similarly expanded. As a community of practice, Consortium participants share information in an open and rapid manner to addresses the complex health care and quality-of-life issues of cancer, transgender and other patients. To ensure that the organization remains contemporary to the needs of the community, the field designed a fully inclusive mechanism for strategic planning and here present the findings of this process. RESULTS: This interprofessional network of medical specialists, scientists, and scholars in the law, medical ethics, religious studies and other disciplines associated with human interventions, explore the relationships between health, disease, survivorship, treatment, gender and reproductive longevity. CONCLUSION: The goals are to continually integrate the best science in the service of the needs of patients and build a community of care that is ready for the challenges of the field in the future.

RESUMO

BACKGROUND: Chlamydia trachomatis (C. trachomatis) prevalence has been reported to be increasing. Whether this is a true increase over time or confounded by increases in testing and/or use of more sensitive assays is to be determined. MATERIALS AND METHODS: One laboratory service has been detecting C. trachomatis for the past 30 years within the Royal Women's Hospital Melbourne. We conducted a retrospective audit of records over the period 1986-2016 from a clinic population routinely offered chlamydia screening. These were women presenting for family planning advice (termination of pregnancy, intrauterine device insertion or considered at high risk), who underwent chlamydia testing in the context of various diagnostic assays used over this time period. Assays utilised included culture, enzyme immunoassay (EIA), DNA probe, and nucleic acid amplification testing (NAAT). Non-parametric test for trend was used to determine significant differences between prevalence estimates across ordered groups. Least squares regression was conducted to describe a linear trend matching known data points. RESULTS: Overall, there was no significant change for chlamydia prevalence which was 2.2%, in the 30-year study period (P = 0.7). Over time diagnostic assays changed from culture, to EIA, DNA probe, to the more sensitive NAAT. The bulk of the positives were in women under 25 years of age (57%). CONCLUSION: Chlamydia prevalence has been stable over 30 years, remaining a problem in young women. Screening for those at risk needs underscoring in a national sexual health program.

RESUMO

BACKGROUND: Colposcopy has been recommended for all women with recurrent post-coital bleeding (PCB) even if their cervical cytology or co-test (involving oncogenic human papillomavirus (HPV) DNA testing and cytology) are negative. AIMS: To determine the risk of cervical cancer and its precursors among women with recurrent PCB with negative cytology or co-test. MATERIALS AND METHODS: A retrospective analysis of two cohorts of women with PCB referred to a tertiary colposcopy clinic. Cohort (1) (n = 1846) between 1 January 2000 and 31 December 2016 (cytology-based screening) and Cohort (2) (n = 215) from 1 January 2018 to 31 December 2019 after introduction of primary HPV screening. RESULTS: In 1217 (65.9%) women in Cohort (1) referred with negative cytology, there was one cancer (0.08%) and 22 high-grade squamous intraepithelial lesions (HSIL (cervical intraepithelial neoplasia 2/3)) on histopathology. In Cohort (2), there was no cancer or HSIL in 83 women with negative co-tests (negative for oncogenic HPV and cytology). False-negative cytology after a negative referral cytology or co-test was low with 2% of repeat cytology at initial colposcopy showing possible HSIL or worse. CONCLUSIONS: Women presenting with PCB and negative cytology alone have a low risk of cancer and could have HPV testing before being triaged to colposcopy. We showed that with the assurance of a negative co-test and the low likelihood of false-negative cytology, these women could avoid colposcopy unless cervical cancer is clinically suspected. There is a need for a larger cohort study to substantiate our findings with more precision.

RESUMO

PURPOSE: With over 80% of paediatric and adolescent cancer patients surviving into adulthood, quality-of-life issues such as future fertility are increasingly important. However, little is known about regret around decisions to pursue or forgo fertility preservation (FP). We investigated the risk of decision regret in families involved in making a FP decision and explored contributive factors. METHODS: Parents and patients ≥ 15 years were invited to participate. Participants completed a 10-item survey, including a validated Decision Regret Scale. Scores ≥ 30 indicated high regret. Free-text response items allowed participants to provide reasons for satisfaction or regret. RESULTS: A total of 108 parents and 30 patients participated. Most (81.4%) reported low regret (mean score 13.7). On multivariate analysis, predictors of low regret included having a FP procedure and a fertility discussion pre-treatment. Most participants believed that FP offers hope for future fertility. Some reported dissatisfaction with the process of decision-making. CONCLUSION: Overall levels of regret in the study population were low, with factors associated with quality, timely discussion and belief in the success of FP technology being predictors of low regret. However, dissatisfaction with the decision-making process itself revealed that refinements to the programme are required to meet families' needs.

RESUMO

Originally absent from the oncologist's consult, then placed in a 'quality of life' rubric, oncofertility should now be an essential part of a comprehensive cancer treatment plan in patients of reproductive age, including adolescents and young adults (AYAs). Oncofertility encompasses the endocrine health of the patient, as well as fertility management options. Thus, pubertal transitions in males and females, bone health, and menstrual health are all part of this discipline, enabling practitioners to work in interdisciplinary teams to solve problems in reproductive health. This review provides a summary of the essential considerations required for the assessement of reproductive risk and choice of fertility preservation options as well as considerations for developing oncofertility services for AYAs.

RESUMO

PURPOSE: Fertility preservation (FP) discussions in children with cancer presents unique challenges due to ethical considerations, lack of models-of-care, and the triadic nature of discussions. This study evaluated a fertility toolkit for clinicians involved in FP discussions with pediatric, adolescent, and young adult patients and parents. MATERIALS AND METHODS: A survey-based, longitudinal study of clinicians at The Royal Children's Hospital Melbourne involved in FP discussions undertaken at 3 time-points: 2014, alongside an education session for baseline assessment of oncofertility practices (survey 1); after each toolkit use to evaluate case-specific implementation (survey 2); 2016, to evaluate impact on clinical practice (survey 3). RESULTS: Fifty-nine clinicians completed survey 1. Over 66% reported baseline dissatisfaction with the existing FP system; 56.7% were not confident in providing up-to-date information. Only 34.5% "often" or "always" provided verbal information; 14.0% "often" or "always" provided written information. Survey 2 was completed after 11 consultations. All clinicians were satisfied with the discussions and outcomes using the toolkit. Thirty-nine clinicians completed survey 3. Over 70% felt confident providing up-to-date FP knowledge, 67.7% "often" or "always" provided verbal information, and 35.4% "often" or "always" provided written information. CONCLUSIONS: Clinicians desire improvement in FP practice. The toolkit provided significant perceived and actual benefits.

RESUMO

Young children with cancer are treated with interventions that can have a high risk of compromising their reproductive potential. 'Fertility preservation' for children who have not yet reached puberty involves surgically removing and cryopreserving reproductive tissue prior to treatment in the expectation that strategies for the use of this tissue will be developed in the future. Fertility preservation for prepubertal children is ethically complex because the techniques largely lack proven efficacy for this age group. There is professional difference of opinion about whether it is ethical to offer such 'experimental' procedures. The question addressed in this paper is: when, if ever, is it ethically justifiable to offer fertility preservation surgery to prepubertal children? We present the ethical concerns about prepubertal fertility preservation, drawing both on existing literature and our experience discussing this issue with clinicians in clinical ethics case consultations. We argue that offering the procedure is ethically justifiable in certain circumstances. For many children, the balance of benefits and burdens is such that the procedure is ethically permissible but not ethically required; when the procedure is medically safe, it is the parents' decision to make, with appropriate information and guidance from the treating clinicians. We suggest that clinical ethics support processes are necessary to assist clinicians to engage with the ethical complexity of prepubertal fertility preservation and describe the framework that has been integrated into the pathway of care for patients and families attending the Royal Children's Hospital in Melbourne, Australia.

RESUMO

AIM: To audit the clinical features and outcomes for all patients referred to our centre with concerns regarding labial appearance. METHODS: Young females referred to a paediatric/adolescent gynaecology tertiary centre between 2000 and 2012 with concerns regarding their labial appearance were retrospectively identified. Adolescents presenting with anomalies were excluded. Retrospective chart review was undertaken to identify reasons for referral, patient characteristics, outcome of referral and concurrent health problems. RESULTS: In total, 46 females presenting with concerns about labial appearance were identified. Five were excluded. Median age of the study population was 14.5 years (range 5-21 years). Only four (9.8%) underwent surgery after a minimum of five consultations each, with mental health review in three of four cases prior to surgery. None of the 41 patients had documented abnormal labia; however, 6 patients had asymmetry, and 3 had a labial width of >5 cm. Of mothers, 24% (n = 10) raised the initial concern regarding labial appearance to a physician, of whom, 50% of patients had a comorbid condition. In total, 70.7% initially reported interference with daily activities, and 87.8% were reassured following discussion. CONCLUSIONS: With appropriate education and counselling, the majority of girls with concerns regarding labial appearance can be managed without surgery. Overall, our data support current international policy that female cosmetic genital surgery not be performed in mature minors unless there are specific indications. More research about characteristics of patients referred with labial concerns, definition of labial size and long-term satisfaction of conservative versus surgical methods is necessary to determine the best approach.

RESUMO

BACKGROUND: Polycystic ovarian syndrome (PCOS) is the most common condition among reproductive-aged women. However, its exact prevalence is unknown. AIMS: To determine the prevalence of PCOS in Australian women aged 16-29 years using the National Institutes of Health (NIH) criteria compared to self-reported PCOS, to compare co-morbidities between the groups and to determine the most distressing aspect of a diagnosis of PCOS for these young women. MATERIALS AND METHODS: Participants were recruited from the Young Female Health Initiative (YFHI) and Safe-D studies. Participants completed questionnaires, physical examinations and blood tests from 2012 to 2016. In March 2016, two supplementary questionnaires were distributed: the first, comprising questions on reproductive health and impact of diagnosis, was sent to participants who self-reported having PCOS in the original studies. The second, comprising general reproductive health questions, was sent to the remainder. RESULTS: The prevalence of PCOS, according to the NIH criteria, was 12% (31/254), while the prevalence of self-reported PCOS was 8% (23/300). Only 35% (8/23) of those with self-reported PCOS actually fulfilled the NIH criteria for PCOS. Comorbidities were relatively similar among groups. Finally, approximately 65% (15/23) were unhappy or worried about their initial PCOS diagnosis, with 72% (13/18) stating fertility concerns were the most distressing aspect of their diagnosis. CONCLUSIONS: The lack of consistent and accurate diagnosis of PCOS in young women potentially leads to over-diagnosis. This creates unnecessary fears of health complications, particularly infertility. Therefore, we recommend the development of standardised criteria with set parameters that allow for better diagnosis of PCOS.

RESUMO

Children diagnosed with cancer who require treatment with chemotherapy and/or radiation therapy have ever-increasing survival rates. However, as a result of such treatment they face the added, and significant, burden of infertility into their futures. Options for fertility preservation and future reproduction for such children do exist, but some such options continue to be considered experimental. Collaborative multidisciplinary teams support children and their families to make decisions about such options in the treatment environment. When collection of gonadal tissue from children is consented to in such circumstances, it is subject to stringent institutional clinical and human research ethics review, often in both the pediatric oncology setting and the fertility setting in which it will be preserved, examined and, potentially, used. Laws and guidelines may support the collection and use of reproductive tissue from children for treatment and research, subject to meeting consent requirements concerning the child and/or their parent(s). This article examines such laws across Australia. It also examines the legal complexities found in some jurisdictions that may hinder research and practice, consequently having a negative impact on the prospects for children with cancer, in relation to their fertility preservation and possibilities for future reproduction.

RESUMO

BACKGROUND: Advances in cancer treatment have led to improved long-term survival after childhood cancer, but often at a price of impaired future fertility. Fertility preservation (FP) in male children and early adolescents poses unique challenges as efficacy is unproven. OBJECTIVES: To describe characteristics of testicular tissue cryopreservation (TTCP) specimens taken from paediatric and adolescent patients, stratified by age, and prior chemotherapy, if any, and to demonstrate evidence for germ cells. MATERIALS AND METHODS: Retrospective review of gonadal biopsies and clinical records of patients consented into the Royal Children's Hospital FP programme between 1987 and 2015. Tissue was sliced into blocks, with one section sent for histopathology prior to cryopreservation. In boys ≥12 years where spermatogenesis could be expected, a portion of tissue was disaggregated completely to look for mature sperm and if found, additional tissue was dissected and the resulting suspension frozen. RESULTS: Testicular tissue cryopreservation specimens in 44 males (0.3-16.8 years) provided an average of 7.8 slices per patient. All the specimens were taken at the same time as another necessary surgical procedure, under one general anaesthesic. There was only one complication of scrotal wound dehiscence. Seven of the forty-four (15.9%) patients had chemotherapy prior to testicular biopsy, while the rest were chemotherapy naïve. Five of these were prepubertal, and two were pubertal patients. Eleven subjects had tissue dissected with mature sperm found in eight. Of these eight patients where sperm were found, all were pubertal with testicular size of more than 10 mL and showing histological evidence of spermatogenesis. No histologic specimen demonstrated any malignant cells. CONCLUSIONS: Testicular tissue cryopreservation can be performed in young patients without delay, preferably prior to cancer treatment. As testicular tissue contains germ cells from which haploid spermatozoa are ultimately derived, future technologies may allow their utilization for fertility in humans. This may be the only hope for biological offspring in some patients undergoing fertility compromising treatment. Retrieval of mature sperm from some pubertal patients, however, offers realistic hope to these patients of future fertility.

RESUMO

OBJECTIVE: To describe clinical presentation and treatment in women younger than 25 years referred to the Royal Women's Hospital colposcopy clinic, before implementation of the National Human Papillomavirus Vaccination Program. METHODS: Retrospective cohort analysis of women younger than 25 years referred to a tertiary hospital colposcopy clinic between 1998 and 2007. Clinical presentation and correlation between cervical cytology, biopsy, and histology at treatment was examined. RESULTS: Approximately 14,635 colposcopies were undertaken in 4104 women (median age, 22 years); 3051 had abnormal referral cytology, of whom, 23.8% had high-grade disease on punch biopsy. High-grade disease was found in 15.1% of those with possible low-grade or low-grade cytology (293/1932), 42.4% of those with possible high-grade or high-grade cytology (474/1119). Sensitivity and specificity of colposcopy for high-grade disease (high-grade epithelial abnormality, adenocarcinoma in situ, cervical cancer up to 2 years follow-up) was 60.0% and 82.3%, respectively. Thirty-nine percent (n = 1180) with abnormal cytology had treatment, of which, 66.6% was ablative. Histological CIN3+ was found in 53.8% of those with a previous high-grade punch biopsy (126/234) at excisional treatment, and 23.0% of those with a previous low-grade punch biopsy (20/87) (relative risk, 2.3 [CI, 1.6-3.5]). Four cancers were detected (0.1% of the total cohort, 0.5% of those with a high-grade biopsy, and 1.7% of those with a high-grade biopsy who underwent excisional treatment.) CONCLUSIONS: Before vaccination, young women experienced a high real-time burden of high-grade disease and high rates of intervention. These baseline data contribute to monitoring of HPV vaccination and revised cervical screening strategies.

RESUMO

BACKGROUND: Little is known about the severity of dysmenorrhoea and attitudes towards its management in young females. OBJECTIVE: The aim of this study was to evaluate the prevalence and severity of dysmenorrhoea in women aged 16-25 years. METHODS: Participants were recruited via targeted Facebook advertising and asked to complete an online questionnaire covering medications, menstruation and lifestyle-related themes. A follow-up questionnaire on dysmenorrhoea was also administered. RESULTS: The prevalence of dysmenorrhoea was 88% (n = 247, mean age 21.5 years, SD 2.6). Only 34% of participants reported consulting a healthcare provider about their pain, whereas 86% consulted other sources. Pain medication was used by 58% of the participants. Dysmenorrhoea was associated with interference with daily activities (P DISCUSSION: Dysmenorrhoea is highly prevalent among these women, with most indicating moderate to severe pain and a significant adverse impact on daily activities. Most women did not obtain information about dysmenorrhoea from healthcare providers, indicating the need for general practitioners to provide accurate information about dysmenorrhoea to young females.
