Fertility issues in survivors from adolescent cancers

Banking on Fertility Preservation: Financial Concern for Adolescent and Young Adult Cancer Patients Considering Oncofertility Services

Purpose: Financial concern is a major issue for adolescent and young adult (AYA) cancer patients. Furthermore, unaddressed oncofertility challenges (e.g., infertility) are linked to psychological distress and decreased overall quality of life. Little is known about how financial concern in terms of oncofertility (i.e., concern regarding affording fertility preservation [FP] services) impacts AYAs' decision making and experiences. Methods: AYA cancer patients (n = 27) aged 12-25 years whose cancer treatment conferred risk of infertility were recruited through electronic health record query. Participants completed semi-structured interviews, which were recorded, transcribed, and deductively coded for themes related to information needs, knowledge of treatment effects on fertility, and reproductive concerns after cancer. Emergent, inductive themes related to financial concern were identified. The Institutional Review Board at the University of Michigan approved this study (HUM#00157267). Results: Financial concern was a dominant theme across the qualitative data. Emergent themes included (1) varied access to health insurance, (2) presence of parental/guardian support, (3) reliance upon financial aid, (4) negotiating infertility risk, and (5) lack of preparation for long-term costs. AYAs relied heavily upon parents for out-of-pocket and insurance coverage support. Some participants sought financial aid when guided by providers. Several participants indicated that no financial support existed for their circumstance. Conclusions: Financial consequences in terms of oncofertility are a major issue affecting AYA cancer patients. The incidence and gravity of financial concern surrounding affording oncofertility services merits attention in future research (measuring financial resources of AYAs' parental/support networks), clinical practice (strategically addressing short- and long-term costs; tailored psychosocial support), and health care policy (promoting legislation to mandate pre- and post-treatment FP coverage).

Prevalence of early and late onset of chronic diseases and multimorbidity and its association with physical, mental and functional health among older Indian adults

BACKGROUND

Identifying people with early and late onset of chronic conditions might help target the subpopulations that are more vulnerable to negative mental, physical and functional health outcomes. The current study aimed to examine the association of early and late onset of chronic single and multiple morbidities with self-perceived physical and mental health, functional limitations and physical inactivity among older Indian adults.

METHODS

Cross-sectional study was conducted using data from the Longitudinal Ageing Study in India (LASI) Wave 1 (2017-2018). The total sample size for the present study was 31,386 older adults age 60 years or older. Multivariable binary logistic regression analysis was used to establish the association between the outcomes (poor perceived physical/mental health, functional difficulty and physical inactivity) and explanatory variables (early [ = < 50 years of age] and late [> 50 years]) onset of chronic illnesses such as hypertension, diabetes, heart attack, heart disease, stroke, cancer, lung disease, arthritis, osteoporosis and psychiatric disease).

RESULTS

Overall, 24.21% of the sample population had poor self-perceived physical health, whereas 8.67% of participants had poor self-perceived mental health. The prevalence of difficulty in ADL, difficulty in IADL, and physical inactivity was 23.77%, 48.36%, and 68.9%, respectively. Odds of poor perceived mental health were higher for the respondents with early as well as late onset of hypertension, stroke, and arthritis; while individuals with late onset of diabetes, and heart disease had higher odds of poor perceived mental health than those without chronic disease. Individuals with early onset of single morbidity were more likely to report ADL difficulty (adjusted odds ratio [AOR]: 1.33, confidence interval [CI]: 1.06-1.67); while those with late onset of single (AOR: 1.34, CI: 1.17-1.53) and multimorbidity (AOR: 1.91, CI: 1.63-2.24) were more likely to report ADL difficulty compared with individuals without morbidity. Individuals with early as well as late-onset of multimorbidity had more than two times higher odds of reporting poor physical health, poor mental health and IADL difficulty compared with individuals without chronic disease.

CONCLUSIONS

The present study revealed that early and/or late onset of chronic single and/or multiple morbidities significantly predicted poor self-perceived physical and mental health, functional limitations and physical inactivity among older Indian adults. The findings further suggest that late onset of chronic diseases such as cancer and stroke and multi-morbidity had stronger associations with physical inactivity that may help identify high risk groups for screening and support.

Lifestyle, Insulin Resistance and Semen Quality as Co-Dependent Factors of Male Infertility

Infertility is a problem that affects millions of couples around the world. It is known as a disease of couples, not individuals, which makes diagnosis difficult and treatment unclear. Male infertility can have many causes, from mechanical ones to abnormal spermatogenesis or spermiogenesis. Semen quality is determined by a number of factors, including those dependent on men themselves, with the number of infertile men growing every year. These include, e.g., diet, physical activity, sleep quality, stress, among many others. As these factors co-exist with insulin resistance, which is a disease closely related to lifestyle, it has been singled out in the study due to its role in affecting semen quality. In order to examine connections between lifestyle, insulin resistance, and semen quality, a review of literature published from 1989 to 2020 in the following databases PubMed/Medline, EMBASE (Elsevier), Scopus, Web of Science, and Google Scholar was performed. Hence, semen quality, environment, and insulin resistance are interrelated, thus it is difficult to indicate which aspect is the cause and which is the effect in a particular relationship and the nature of possible correlations. Since the influence of lifestyle on semen quality has been extensively studied, it is recommended that more thorough research be done on the relationship between insulin resistance and semen quality, comparing the semen quality of men with and without insulin resistance.

"Queer Insights": Considerations and Challenges for Assessing Sex, Gender Identity, and Sexual Orientation in Oncofertility Research

This article addresses issues related to clinical and research approaches to oncofertility for adolescent and young adult (AYA) sexual and gender minority (SGM) cancer patients. Limited attention has been dedicated to understanding the extent to which oncofertility services are appropriately and equitably delivered to AYAs with diverse orientations toward sexual orientation, gender identity, and future family. Unresolved challenges to conducting research with this vulnerable population perpetuate a lack of adequate knowledge about SGM AYA oncofertility needs. Therefore, the purpose of this paper is to inform considerations of sex, gender identity, and sexual orientation for investigations that include SGM AYAs. In order to improve the knowledge base and clinical services for this population, we discuss (1) challenges to sampling this population; (2) categorization and survey logic (e.g., skip patterns) in light of fluid sexual orientation and gender identities; and (3) clinical implications of accurately assessing sex and gender for oncofertility research and practice. We also recommend strategies for producing inclusive and accurate assessments of sexual and gender identity categories in both research and clinical encounters with SGM AYAs. Incorporating "queer insights" into empirical research - that is, positioning queer theory at the center of oncofertility study design - is suggested as a future direction for oncofertility research and practice.

Communication and ethical considerations for fertility preservation for patients with childhood, adolescent, and young adult cancer: recommendations from the PanCareLIFE Consortium and the International Late Effects of Childhood Cancer Guideline Harmonization Group

Patients with childhood, adolescent, and young adult cancer who will be treated with gonadotoxic therapies are at increased risk for infertility. Many patients and their families desire biological children but effective communication about treatment-related infertility risk and procedures for fertility preservation does not always happen. The PanCareLIFE Consortium and the International Late Effects of Childhood Cancer Guideline Harmonization Group reviewed the literature and developed a clinical practice guideline that provides recommendations for ongoing communication methods for fertility preservation for patients who were diagnosed with childhood, adolescent, and young adult cancer at age 25 years or younger and their families. Moreover, the guideline panel formulated considerations of the ethical implications that are associated with these procedures. Grading of Recommendations Assessment, Development and Evaluation methodology was used to grade the evidence and recommendations. In this clinical practice guideline, existing evidence and international expertise are combined to develop transparent recommendations that are easy to use to facilitate ongoing communication between health-care providers and patients with childhood, adolescent, and young adult cancer who might be at high risk for fertility impairment and their families.

Fertility preservation for young adults, adolescents, and children with cancer

Options for fertility preservation (FP) through cryopreservation methods are currently available for young adults, adolescents, and children. Guidelines for FP have been provided by international clinical societies, and emergency procedures aimed at FP have been implemented into clinical practice worldwide. In this article, we review the current data on clinical standards of emergency FP in patients who are facing gonadotoxic effects of cancer treatment, and we also describe the methods that are still under development, usually denoted as experimental. In Sweden, programmes for FP have been established at large university hospitals, thus covering the whole country. The Swedish publicly financed health care covers both assisted reproduction for treatment of infertility and the cryopreservation of gametes or gonadal tissue when there is a medical indication, such as the risk to become infertile due to oncologic treatment; hence the access to FP is ensured for the whole population. At our centre at Karolinska University Hospital in Stockholm, methods for FP have been offered since 1988. In this article, we also review the oncologic indications for FP in our patient cohort of >3000 individuals during the period 1988-2018.

Recovery of Spermatogenesis Following Cancer Treatment with Cytotoxic Chemotherapy and Radiotherapy

The survival rates of boys and men with cancer have increased due to advances in cancer treatments; however, maintenance of quality of life, including fertility preservation, remains a major issue. Fertile male patients who receive radiation and/or chemotherapy face temporary, long-term, or permanent gonadal damage, particularly with exposure to alkylating agents and whole-body irradiation, which sometimes induce critical germ cell damage. These cytotoxic treatments have a significant impact on a patient's ability to have their own biological offspring, which is of particular concern to cancer patients of reproductive age. Therefore, various strategies are needed in order to preserve male fertility. Sperm cryopreservation is an effective method for preserving spermatozoa. Advances have also been achieved in pre-pubertal germ cell storage and research to generate differentiated male germ cells from various types of stem cells, including embryonic stem cells, induced pluripotent stem cells, and spermatogonial stem cells. These approaches offer hope to many patients in whom germ cell loss is associated with sterility, but are still experimental and preliminary. This review examines the current understanding of the effects of chemotherapy and radiation on male fertility.

Support needs of adolescents' post-cancer treatment: A systematic review

INTRODUCTION

The study aimed to investigate the support needs for adolescents' post-cancer treatment.

MATERIALS AND METHODS

A systematic literature review was conducted, articles were obtained from the following databases, Science Direct, PubMed and SCOPUS. Additional studies were identified from the reference lists of articles included in the review.

RESULTS

119 articles were identified as potentially relevant, of these, a total of 16 articles were nominated to be included in the review for analysis.

CONCLUSION

The role of relationships and key workers were important to enabling survivors to self-manage. Studies have commended the role of friendships during the cancer treatment process but also as a means to coping with issues relating to survivorship. Using a coping mechanism thought to be beneficial by the survivor often improves their overall wellbeing. The eagerness to continue a normal successful life post-cancer treatment seems to be over-shadowed by the fear of not being able to conceive offspring. This, in turn, can impact the psychological wellbeing of survivors, thus signifying the need to develop ways in supporting these individuals. With research into quality of life (QoL) and survivorship issues continuing to progress and reach new heights, there is still much to be done.

Threat of biographical disruption: the gendered construction and experience of infertility following cancer for women and men

BACKGROUND

Infertility is a major concern for people with cancer and their partners. There have been calls for further research on the gendered nature of psychosocial, emotional and identity concomitants of fertility post-cancer across women and men.

METHOD

The gendered construction and experience of infertility following cancer was examined through a survey of 693 women and 185 men, and in-depth one-to-one interviews with a subsample of survey respondents, 61 women and 17 men, purposively selected across cancer types and age groups. Thematic decomposition was used to examine the open ended survey responses and interviews. The chi square test for independence was used to test for group differences between women and men on closed survey items.

RESULTS

In the thematic decomposition, infertility was identified as providing a 'Threat of Biographical Disruption' which impacted on life course and identity, for both women and men. Subthemes identified were: 'Parenthood as central to adulthood'; 'Infertility as a threat to gender identity'; ' Unknown fertility status and delayed parenthood'; 'Feelings of loss and grief'; 'Absence of understanding and support'; 'Benefit finding and renegotiation of identity'. In the closed survey items, the majority of women and men agreed that they had always 'wanted to be a parent' and that 'parenthood was a more important life goal than a satisfying career'. 'It is hard to feel like a true adult until you have a child' and impact upon 'my feelings about myself as a man or a woman' was reported by both women and men, with significantly more women reporting 'I feel empty because of fertility issues'. Many participants agreed they 'could visualise a happy life without a child' and there is 'freedom without children'. Significantly more men than women reported that they had not discussed fertility with a health care professional.

CONCLUSION

The fear of infertility following cancer, or knowledge of compromised fertility, can have negative effects on identity and psychological wellbeing for both women and men, serving to create biographical disruption. Support from family, partners and health care professionals can facilitate renegotiation of identity and coping.

Young Adult Female Cancer Survivors' Concerns About Future Children's Health and Genetic Risk

As young adult female cancer survivors (aged 18-35) make family-building decisions, understanding the specific nature of their concerns is important. We evaluated survivors' concerns about potential health risks to future children including genetic susceptibility for cancer with an internet-based survey study (N = 187). Sixty-five percent reported concern about passing on a genetic cancer risk to their children, and scores did not vary regardless of association with cancer at high risk for genetic transmission. Genetic counseling and education about family-building options may be important to survivors concerned about health risks to offspring to support family-building decisions based on personalized medical information.

Human sperm cryopreservation in cancer patients: Links with deprivation and mortality

Evidence is mounting for a relationship between human semen quality and environmental/lifestyle/socioeconomic factors including long term health outcomes such as mortality. The relationship between pre-freeze and post-thaw semen quality in cancer patients and these factors are unknown. Frozen semen from 217 cancer patients was thawed and analysed using a validated CASA method. Post-thaw quality was matched and compared with WHO semen analysis performed prior to storage. The English Indices of Deprivation 2010 were matched with patients and then examined for relationships with pre-freeze and post-thaw semen quality. There is a relationship between semen quality and deprivation in cancer patients. Compared with pre-freeze semen quality, post-thaw semen quality has a stronger relationship with deprivation. Sperm cryopreservation may have potential as a systemic health diagnostic test and is predictive of cancer patient mortality.

Cryopreservation of reproductive material before cancer treatment: a qualitative study of health care professionals' views about ways to enhance clinical care

BACKGROUND

Cancer treatment can diminish fertility in women and men. The need for fertility preservation is growing as increasing numbers of people survive cancer. Cryostorage of reproductive material to preserve potential for conception for cancer survivors has moved from being experimental to being a part of clinical management of women and men who are diagnosed with cancer in their reproductive years. There is little existing evidence about how fertility preservation services can be enhanced to meet the complex needs of patients who are diagnosed with cancer in their reproductive years. The aim of this research was to inform clinical practice development by drawing on the collective experience and knowledge of staff at well-established clinics that offer fertility preservation before cancer treatment.

METHODS

A qualitative research model was adopted using semi-structured interviews with professionals involved in the care of people who freeze reproductive material before cancer treatment. In the state of Victoria, Australia, two large assisted reproductive technology (ART) centres have been providing fertility preservation services for more than two decades. An invitation to participate in a semi-structured interview about clinical care in the context of fertility preservation was emailed to past and current staff members. To capture diverse perspectives, informants were sought from all relevant professions: fertility specialists, andrologists, nurses, embryologists/scientists, counsellors, and administrative staff. Transcripts were analysed thematically.

RESULTS

Thirteen key informants were interviewed from August 2013 to February 2014. The identified themes relating to enhancing clinical care in a fertility preservation service were communication between oncology and ART specialists; managing urgency; managing patients' expectations; establishing and implementing protocols, systems, and data bases; and maintaining contact with patients.

CONCLUSION

The collective knowledge of this study's informants, who represent multidisciplinary teams with more than two decades' experience in fertility preservation, yields important insights into strategies that fertility preservation services can employ to promote the integration of oncology and fertility care, the psychosocial care of patients, data recording and monitoring, and reporting of outcomes.

Contemporary and future insights into fertility preservation in male cancer patients

In recent years, survival rates of cancer patients have increased, resulting in a shift of focus from quantity to quality of life. A key aspect of quality of life is fertility potential; patients suffering from iatrogenic infertility often become depressed. Since many cancer therapies—chemotherapy, radiotherapy and/or surgery—and even cancer itself have detrimental effects on the male reproductive system, it is important to preserve fertility before any treatment commences. Currently, the only reliable method of male fertility preservation is sperm banking. For patients who are unable to provide semen samples by the conventional method of masturbation, there are other techniques such as electroejaculation, microsurgical epididymal sperm aspiration and testicular sperm extraction that can be employed. Unfortunately, it is presently impossible to preserve the fertility potential of pre-pubertal patients. Due to the increasing numbers of adolescent cancer patients surviving treatment, extensive research is being conducted into several possible methods such as testicular tissue cryopreservation, xenografting, in vitro gamete maturation and even the creation of artificial gametes. However, in spite of its ease, safety, convenience and many accompanying benefits, sperm banking remains underutilized in cancer patients. There are several barriers involved such as the lack of information and the urgency to begin treatment, but various measures can be put in place to overcome these barriers so that sperm banking can be more widely utilized.

Growth Hormone Ameliorates the Radiotherapy-Induced Ovarian Follicular Loss in Rats: Impact on Oxidative Stress, Apoptosis and IGF-1/IGF-1R Axis

Radiotherapy is one of the standard cytotoxic therapies for cancer. However, it has a profound impact on ovarian function leading to premature ovarian failure and infertility. Since none of the currently available methods for fertility preservation guarantees future fertility, the need for an effective radioprotective agent is highly intensified. The present study investigated the mechanisms of the potential radioprotective effect of growth hormone (GH) on γ irradiation-induced ovarian failure and the impact of the insulin like growth factor 1 (IGF-1) in the underlying protection. Immature female Sprague-Dawley rats were either exposed to single whole body irradiation (3.2 Gy) and/or treated with GH (1 mg/kg s.c). Experimental γ-irradiation produced an array of ovarian dysfunction that was evident by assessment of hormonal changes, follicular development, proliferation marker (PCNA), oxidative stress as well as apoptotic markers. In addition, IGF-1/IGF-1R axis expression was assessed using real-time PCR and immunolocalization techniques. Furthermore, after full maturity, fertility assessment was performed. GH significantly enhanced follicular development and restored anti-Mullerian hormone serum level as compared with the irradiated group. In addition, GH significantly ameliorated the deleterious effects of irradiation on oxidative status, PCNA and apoptosis. Interestingly, GH was shown to enhance the ovarian IGF-1 at transcription and translation levels, a property that contributes significantly to its radioprotective effect. Finally, GH regained the fertility that was lost following irradiation. In conclusion, GH showed a radioprotective effect and rescued the ovarian reserve through increasing local IGF-1 level and counteracting the oxidative stress-mediated apoptosis.

Review and follow-up of patients using a regional sperm cryopreservation service: ensuring that resources are targeted to those patients most in need

Are all patients undergoing chemotherapy for long-term sperm banking at risk of permanent sterility? Male fertility is generally lower in men with cancer and all patient groups are at risk of azoospermia. Careful management is required to ensure that samples are not stored for excessively long periods should they not be required. A retrospective analysis of 1688 patient records and prospective recall of patients for semen testing were performed. Pre-therapy fertility was compared with a group of pre-vasectomy patients as a comparator. Those who fail to bank spermatozoa, rates of disposal of samples and the utilization in assisted reproduction were also examined. Sperm quality was poorest in testicular cancer (TC) patients followed by those with Hodgkin's lymphoma (HL) prior to treatment. Post-therapy data were available in 376 patients (42%). Sperm number was lowest (and azoospermia highest at 77%) in patients with HL treated with regimens other than adriamycin, bleomycin, vinblastine and dacarbazine (ABVD). Non-HL NHL and leukaemic patients had similarly high rates of azoospermia at 46 and 55%. HL patients treated with ABVD (11%) and TC patients (9.7%) had the lowest rates of azoospermia. Azoospermia was seen in every treatment group except for TC patients receiving carboplatin. Only 45 patients used their samples in ART (4.5%) in 10 years. Little is known about the fertility status of the patients not coming forward for follow-up testing, those conceiving naturally, those with no intention of conceiving and some which may have psychological reasons for not attending. In conclusion, virtually all patients undergoing chemotherapy are potentially at risk of temporary or permanent infertility. However, as uptake and utilization of stored material remain low, sperm banks should be carefully managed to ensure that resources are targeted to the patients most in need.

Practices of pediatric oncology and hematology providers regarding fertility issues: a European survey

BACKGROUND

Fertility is impaired in many survivors of childhood cancer following treatment. Preservation of fertility after cancer has become a central survivorship concern. Nevertheless, several doctors, patients, and families do not discuss fertility and recommendations for fertility preservation in pediatrics are still lacking. Recommendations based on scientific evidence are needed and before their development we wanted to assess the practice patterns of fertility preservation in Europe.

PROCEDURES

On behalf of the PanCare network, we sent a questionnaire to pediatric onco-hematology institutions across Europe. The survey consisted of 21 questions assessing their usual practices around fertility preservation.

RESULTS

One hundred ninety-eight institutional representatives across Europe received the survey and 68 (response rate 34.3%) responded. Pre-treatment fertility counseling was offered by 64 institutions. Counseling was done by a pediatric onco-hematologist in 52% (33/64) and in 32% (20/64) by a team. The majority of institutions (53%) lacked recommendations for fertility preservation. All 64 centers offered sperm banking; eight offered testicular tissue cryopreservation for pre-pubertal males. For females, the possibility of preserving ovarian tissue was offered by 40 institutions.

CONCLUSIONS

There is a high level of interest in fertility preservation among European centers responding to our survey. However, while most recommended sperm cryopreservation, many also recommended technologies whose efficacy has not been shown. There is an urgent need for evidence-based European recommendations for fertility preservation to help survivors deal with the stressful topic of fertility.

Preserving Fertility in Children and Adolescents with Cancer

In the face of excellent survival rates for pediatric and adolescent cancer, preserving the opportunity to have biological children is an important component of long term quality of life. Yet, modern chemotherapeutic regimens continue to pose a threat to fertility. The only fertility preservation methods available to pre-pubertal children of both genders is cryopreservation of gonadal tissue, a highly experimental intervention, or shielding/re-location of reproductive tissue in the setting of radiation. These techniques are available in the post pubertal population as well, but post pubertal patients also have the option for cryopreservation of gametes, a process that is much simpler in males than females. For this reason, prior to the initiation of therapy, sperm banking should be considered standard of care for males, while consideration of embryo or oocyte cryopreservation should be limited to those females at risk of developing ovarian failure. Attention to reproductive health and fertility preservation should continue after the completion of therapy. Establishing programs that streamline access to current fertility preservation techniques will assist in ensuring that all eligible patients can avail themselves of current options.

Why don't some men with banked sperm respond to letters about their stored samples?

Abstract Long-term storage of banked sperm, especially when it is not needed, for reproductive purposes, is costly and poses practical problems for sperm banks. For sperm banks to function efficiently, men must understand the implications of unnecessary storage, and make timely decisions about disposal of their own samples. Men who bank sperm prior to cancer treatment are routinely offered follow-up consultations to test their fertility, update consent and, where necessary, expedite referral for Assisted Conception. Yet sperm banks report that men do not respond to letters, suggesting samples are stored needlessly. We conducted semi-structured interviews with six men with a history of not responding to letters, to document reasons for non-response. Interviews were transcribed and analysed using Interpretive Phenomenological Analysis. Men's reasons for not responding are a complex interplay between past, present and future perspectives. In terms of their past, information is important on diagnosis, because men must understand that fertility can change after treatment. Present and future concerns focus on fears of being told fertility has not recovered and being pressured to dispose of banked sperm. The challenge is to devise invitation letters that address men's concerns while offering them tangible benefits and peace of mind.

Fertility preservation during cancer treatment: clinical guidelines

The majority of children, adolescents, and young adults diagnosed with cancer today will become long-term survivors. The threat to fertility that cancer treatments pose to young patients cannot be prevented in many cases, and thus research into methods for fertility preservation is developing, aiming at offering cancer patients the ability to have biologically related children in the future. This paper discusses the current status of fertility preservation methods when infertility risks are related to surgical oncologic treatments, radiation therapy, or chemotherapy. Several scientific groups and societies have developed consensus documents and guidelines for fertility preservation. Decisions about fertility and imminent potentially gonadotoxic therapies must be made rapidly. Timely and complete information on the impact of cancer treatment on fertility and fertility preservation options should be presented to all patients when a cancer treatment is planned.

The importance of fertility preservation in cancer patients

The potential risks of anti-cancer therapy for male and female fertility are well understood, yet evidence suggests that fewer patients than predicted actually preserve their fertility before therapy begins. Studies of post-pubertal males and females suggest that the approach of health professionals in oncology is vital in facilitating successful sperm and egg banking. For men, this seems to be compounded by a general lack of understanding about their personal risk of infertility. Those involved in delivering anticancer therapy therefore have a vital role to play in providing timely information and facilitating efficient referral to fertility services. In the future, this is likely to become more important if new fertility preservation strategies such as ovarian and testicular tissue banking become more routinely used, with implications for both pre- and post-pubertal individuals.

Discussing fertility preservation at the time of cancer diagnosis: dissatisfaction of young females

BACKGROUND

Sperm banking is widely available for post-pubertal male cancer patients but options for females remain limited. Anecdotal evidence suggests that fertility issues may be inadequately discussed with females. To understand the experience of both sexes in the UK, surveys of young cancer survivors were performed 7 years apart.

PROCEDURE

Data were collected from young cancer survivors aged over 13 years at diagnosis, attending support group conferences held in 2004 and 2011. Data were collected anonymously using remote handsets in response to questions projected on the screen during plenary sessions.

RESULTS

A total of 81 female and 69 males responded in 2004, and 69 females and 71 males in 2011. In both years, most males reported fertility discussions taking place before treatment started and they were generally satisfied with it. However in both years, fewer females recall a discussion about fertility and they were generally less satisfied. Although in 2011 more females reported a fertility discussion prior to the beginning of treatment, they were no more satisfied than the females in 2004 whose fertility discussion were more likely to take place after treatment had started.

CONCLUSIONS

Whilst male cancer survivors in the UK are generally satisfied about the frequency and timing of discussions about fertility, females are not. Although in 2011 fertility discussions with females more often took place before treatment began, they were no more satisfied than females in 2004. This may reflect the approach by professionals or the absence of effective fertility preservation strategies for them.

Implications of sperm banking for health-related quality of life up to 1 year after cancer diagnosis

Background:

Sperm banking is recommended for all men diagnosed with cancer where treatment is associated with risk of long-term gonadatoxicity, to offer the opportunity of fatherhood and improved quality of life. However, uptake of sperm banking is lower than expected and little is known about why men refuse. Our aims were to determine: (i) demographic and medical variables associated with decisions about banking and (ii) differences in quality of life between bankers and non-bankers at diagnosis (Time 1 (T1)) and 1 year later (Time 2 (T2)).

Methods:

Questionnaires were completed by 91 men (response rate=86.67%) at T1 and 78 (85.71% response rate) at T2.

Results:

In all, 44 (56.41%) banked sperm. They were younger and less likely to have children than non-bankers. In a subset of men who were not sure if they wanted children in the future (n=36), 24 banked sperm. Among this group, those who banked were younger, more satisfied with clinic appointments and less worried about the health of future children. At T2, there were no differences in quality of life between bankers and non-bankers.

Conclusion:

For those who are uncertain about future reproductive plans, decisions depend on their health on diagnosis and satisfaction with clinic care. We conclude that extra care should be taken in counselling younger men who may have given little consideration to future parenting. Results support previous findings that the role of the doctor is vital in facilitating decisions, especially for those who are undecided about whether they wanted children in the future or not.

Fertility-preserving treatment options in patients with malignant hematological diseases

The number of patients of reproductive age diagnosed with various malignant hematological diseases increases every year. These patients undergo chemotherapy, radiotherapy, and various other treatments that may have gonadotoxic effects. The life expectancy of these patients is increasing rapidly due to the variety of treatment options. As such, an increasing number of patients-as well as their parents and spouses-express their concerns about the patient's fertility post treatment. In the present review it was aimed to provide an overview of current fertility-preserving treatment options and the future of fertility preservation.

Finding out about sperm banking: what information is available online for men diagnosed with cancer?

Sperm banking is routinely offered to men where there is a risk of infertility following cancer treatment but uptake is lower than expected. Since these men may turn to the internet for information, we used the search engine www.google.com to identify the material available about sperm banking and fertility preservation options. Sixty-six resources (NHS/Private Clinic, Charity, Press Releases, General and Forums/Blogs) fulfilled the criteria for inclusion and were examined for quality including readability, layout and content. The most frequently reported information related to: (1) effects of cancer treatment on fertility (77.3%); (2) reasons to bank sperm (69.7%); and (3) fertility recovery after treatment (57.6%). Information about maintaining contact with the sperm bank (18.2%) and disposal of banked samples (10.6%) was less often included. The quality of information available on the Internet about sperm banking was variable. The readability of all resources was assessed as 'fairly difficult', i.e. reading skills required were too complex for the average member of the public to understand. Furthermore, visual presentation of material (e.g. lay out) did not facilitate easy reading. More attention should be given to information about longer-term issues, such as fertility recovery and the use or disposal of banked sperm.

Routine cryopreservation of spermatozoa is safe--evidence from the DNA methylation pattern of nine spermatozoa genes

PURPOSE

Assess short- and mid-term impact of cryopreservation on DNA methylation status of different genes in spermatozoa.

METHODS

Semen samples from 10 healthy normozoospermic men were collected at the Department of Clinical Andrology of the Centre of Reproductive Medicine and Andrology (Muenster, Germany). Each was divided into four equal aliquots: 1) untreated, 2) diluted in cryoprotectant, 3) short term (2 days) cryopreserved and 4) mid term (4 weeks) cryopreserved. Samples were "swim-up" purified prior to analysis. DNA fragmentation was measured using comet assay and Flow cytometric evaluation with Acridine Orange (FCEAO). The degree of methylation of nine genes was determined by bisulfite pyrosequencing of genomic DNA.

RESULT(S)

Analysis of three maternally imprinted genes (LIT1, SNRPN, MEST), two paternally imprinted genes (MEG3, H19), two repetitive elements (ALU, LINE1), one spermatogenesis-specific gene (VASA) and one gene associated with male infertility (MTHFR) in semen samples demonstrated no alteration in methylation pattern regardless of duration of cryopreservation.

CONCLUSION(S)

The lack of any changes in the sub-fraction of the genome examined in our study, implies that sperm DNA methylation is unaffected by cryopreservation and suggests that this daily clinical routine is safe in terms of DNA methylation.

Fertility Preservation in Adolescents and Young Adults With Cancer

Preservation of fertility is important to adolescent and young adult (AYA) survivors of cancer. Many survivors will maintain their reproductive potential after the successful completion of treatment for cancer. However total-body irradiation, radiation to the gonads, and chemotherapy regimens containing high-dose alkylators can place women at risk for acute ovarian failure or premature menopause and men at risk for temporary or permanent azoospermia. The most effective and established means of preserving fertility in this population is embryo cryopreservation in women and sperm cryopreservation in men before the initiation of cancer-directed therapy. Cryopreservation of mature oocytes is also becoming more commonplace as methods of thawing become more sophisticated. The use of in vitro fertilization and intracytoplasmic sperm injection has added to the viability of sperm and oocyte cryopreservation. Cryopreservation and transplantation of gonadal tissue in both males and females remains experimental but continues to be evaluated. Hormonal suppression has not been shown to be effective in males but may have promise in females, although larger scale trials are needed to evaluate this. Providing information about risk of infertility and possible interventions to maintain reproductive potential are critical for the AYA population at the time of diagnosis. Given the competing demands of providing complicated and detailed information about cancer treatment, the evolving information related to fertility preservation, and the ethical issues involved, it may be preferable, where possible, to have a specialized team, rather than the primary oncologist, address these issues with AYA patients.

Tamoxifen decreases ovarian follicular loss from experimental toxicant DMBA and chemotherapy agents cyclophosphamide and doxorubicin in the rat

INTRODUCTION

we serendipitously observed a protective effect of tamoxifen against depletion of ovarian follicles by 7,12-dimethylbenzanthracene (DMBA), a chemical carcinogen, during a cancer prevention study. Such ovarian protection is being sought as an alternative approach to fertility preservation in human cancer patients.

METHODS

rats received tamoxifen (0, 1 mg or 2.5 mg/kg/d) and DMBA (0, 1, 2 mg/kg/wk) or cyclophosphamide (0, 35, 50 mg/kg/wk). Ovarian follicles were quantified and effects on fertility and litter size were tested. Cultured oocytes were exposed to chemotherapy drug doxorubicin, with or without 4-hydroxytamoxifen (4HT).

RESULTS

DMBA and cyclophosphamide decreased the number of primordial and total follicles, and this reduction was prevented by tamoxifen. Cyclophosphamide tended to reduce fertility and lessened neonatal survival. Tamoxifen reversed these defects. Doxorubicin caused oocyte fragmentation which was prevented by 4HT.

CONCLUSIONS

tamoxifen decreases follicle loss and improves reproductive function following exposure to ovarian toxicants including chemotherapy drugs in the female rat.

Measuring the psychosocial health of adolescent and young adult (AYA) cancer survivors: a critical review

Background

Adolescent and young adult (AYA) cancer survivors require psychometrically rigorous measures to assess their psychosocial well-being. Without methodologically adequate scales the accuracy of information obtained on the prevalence of needs, predictors of risk, and the potential success of any interventions, can be questioned. This review assessed the psychometric properties of measures designed specifically to identify the psychosocial health of this unique population.

Methods

Medline, PsycINFO, CINAHL and EMBASE databases were searched to identify measures developed to assess the psychosocial health of AYA cancer survivors. Searches were limited to the years 1998-2008. A search of Medline revealed that the number of publications related to the assessment of psychosocial well-being in AYA cancer survivors prior to this period were minimal. The psychometric properties of identified measures were evaluated against pre-determined and generally accepted psychometric criteria including: reliability (internal consistency and test-retest); validity (face, content, construct, and criterion); responsiveness; acceptability; and feasibility.

Results

Seven quality of life measures met the inclusion criteria. No measures of unmet need were identified. All seven measures reported adequate internal consistency, face, content, and construct validity. Test-retest reliability, criterion (predictive) validity, responsiveness, acceptability, and feasibility were rarely examined.

Conclusions

There is a need to further evaluate the psychometric properties of existing quality of life measures for AYA cancer survivors. Valid, reliable, and acceptable measures which can assess the psychosocial needs of this population should also be developed.

'Swimming against the tide'--the influence of fertility matters on the transition to adulthood or survivorship following adolescent cancer

Psychosocial research into cancer-related fertility has concentrated on fertility preservation or adult survivors' concerns. This study reports on its hitherto unreported impact over the time from diagnosis to survivorship. Thirty-eight men and women aged<30, diagnosed as teens, were recruited to an exploratory qualitative study. Analysis used the constant comparison method, considered conceptually within a lifespan approach. Four key experiences of managing fertility matters influenced, or were influenced by, the aftermath of cancer treatment: (1) prioritising 'normality' and marginalising fertility; (2) fertility concerns compromising 'normality'; (3) ongoing impairments/health concerns mediating fertility matters; (4) fertility concerns dominating the cancer legacy. Professional and social networks provided few opportunities to ask questions, receive information, process feelings or develop handling strategies. Beliefs about the extent of fertility damage did not necessarily relate to information received. For some, fertility matters affected identity, well-being and life planning as well as reproductive function. This was not restricted to particular ages, life stages, gender or time since treatment ended and was heightened by associated stigma and silence. Opportunities for dialogue should be offered regularly across health and social work disciplines given fertility's psychological and social as well as medical significance.

Ethical issues regarding fertility preservation in adolescents and children

Certain forms of treatment for cancer in children and adolescents may significantly affect their fertility. Oncologists and specialists in reproductive medicine are attempting to use various methods of fertility preservation to address this problem. However, major medical/biological issues must be resolved before many of these methods can be considered accepted medical treatments. In addition, ethical considerations that such treatments bring to the fore, including those relevant to assent by children and the provision of experimental treatment to children, must be taken into account. This article addresses the current and future medical and ethical status of the development of fertility-preserving treatment for adolescents and children who are to receive cancer treatment.

Psychological aspects of fertility preservation in men and women affected by cancer and other life-threatening diseases

BACKGROUND

With advances in treatment, the number of young cancer survivors who may benefit from fertility preservation is growing. The aim of this study was to review the literature investigating psychological aspects of fertility issues and fertility preservation in patients undergoing fertility-compromising therapy for cancer or other life-threatening diseases, previous to or during their reproductive lifespan.

METHODS

Articles were identified in PubMed, Embase and PsycLIT as well as manually retrieved from literature citations for the time period from 1999 to 2008. Inclusion criteria were (i) qualitative or quantitative design, (ii) focus on patients previous to or during their reproductive lifespan and (iii) dealing with aspects such as (1) impact of fertility issues in cancer patients or (2) health professionals' and/or patients' attitudes towards fertility preservation or (3) counselling.

RESULTS

Twenty-four studies were identified. According to the studies on aspect (1), fertility is an important issue for cancer patients. Health professionals as well as patients and parents consider fertility preservation as an important option for young cancer patients; all parties involved, however, were noted to have knowledge and information deficits. Patients recalling counselling about the impact of cancer treatment on fertility ranged from 34% to 72%. Counselling is far from being offered globally to all patients at risk, and providing information seems to be selective.

CONCLUSIONS

The existing literature demonstrates the need for and the limits of current counselling. Future research should target the means to facilitate the decision-making process for patients and health professionals.
