Sexual and reproductive complications and concerns of survivors of childhood, adolescent and adult cancer. J Cancer Surviv 2024; 18:1201-1210. [PMID: 36991269 PMCID: PMC11324690 DOI: 10.1007/s11764-023-01349-6] [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: 08/11/2022] [Accepted: 02/10/2023] [Indexed: 03/31/2023]
Abstract
PURPOSE Cancer survivors may experience infertility and sexual dysfunction following cancer treatment. Survivors report significant gaps in oncofertility care and consider these issues important, yet they are rarely discussed. The aims of this study were to evaluate survivors' sexual and reproductive complications across age groups and to identify specific groups of survivors at risk for sexual and reproductive complications. METHOD We report data collected from survivors of cancers diagnosed in childhood, adolescence and adulthood following the development and piloting of a reproductive survivorship patient reported outcome measure (RS-PROM). RESULTS One hundred and fifty survivors participated in the study (mean age at cancer diagnosis was 23.2 years [SD, 10.3 years]). About 68% of participants expressed concerns about their sexual health and function. Survivors (50%) expressed at least one body image concern, with the female gender the most common risk factor for all subgroups. A total of 36% of participants reported at least one concern regarding their fertility, with more male than female survivors reporting fertility preservation prior to treatment. Females compared with male participants were more likely to feel less physically attractive after treatment (OR = 3.83, 95% CI = 1.84-7.95, p < 0.001). More females than males were also more likely to feel dissatisfied with the appearance of a scar(s) after treatment (OR = 2.36, 95% CI = 1.13-4.91, p = 0.02). CONCLUSION The RS-PROM identified multiple reproductive complications and concerns for cancer survivors in the survivorship period. IMPLICATIONS FOR CANCER SURVIVORS Utilising the RS-PROM in conjunction with a clinic appointment could help identify and address cancer patients' concerns and symptoms.

Abstract
Fertility capacity has been shown to be one of the main concerns of young cancer survivors. Gonadotoxic treatments may lead to both premature ovarian failure and/or infertility. This review aimed to define which, and when, reproductive indicators should be followed-up to help doctors to counsel patients regarding their fertility and ovarian function, and to determine if a second stage of fertility preservation after the end of cancer treatment is clinically relevant. Longitudinal assessment of anti-Müllerian hormone (AMH) concentrations during cancer treatment indicates the degree of follicular depletion, and allows discrimination between low and high gonadotoxic treatments. Sustained low AMH concentrations after treatment, especially in the case of alkylating protocols, may reduce the duration of the conception window significantly, and expose the patient to the risk of premature ovarian failure. It remains unknown whether this may impact further fertility capacity because of the lack of systematic follow-up of adolescent and young adult (AYA) women after chemo-radiotherapy. It appears that dedicated reproductive follow-up of AYA women under cancer treatment is needed to refine fertility preservation strategies, and to determine if low AMH concentrations after treatment impact the chance of pregnancy in this specific survivor population.

Abstract
There are >1.9 million survivors of adolescent and young adult cancers (AYA, diagnosed at ages 15-39) living in the U.S. today. Epidemiologic studies to address the cancer burden in this group have been a relatively recent focus of the research community. In this article, we discuss approaches and data resources for cancer epidemiology and health services research in the AYA population. We consider research that uses data from cancer registries, vital records, healthcare utilization, and surveys, and the accompanying challenges and opportunities of each. To illustrate the strengths of each data source, we present example research questions or areas that are aligned with these data sources and salient to AYAs. Integrating the respective strengths of cancer registry, vital records, healthcare data, and survey-based studies sets the foundation for innovative and impactful research on AYA cancer treatment and survivorship to inform a comprehensive understanding of diverse AYA needs and experiences.

Reproductive Health Outcomes among Adolescent and Young Adult Cancer Patients: A Systematic Review and Meta-Analysis. Cancers (Basel) 2023; 15:cancers15061707. [PMID: 36980593 PMCID: PMC10046594 DOI: 10.3390/cancers15061707] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2023] [Revised: 02/28/2023] [Accepted: 03/03/2023] [Indexed: 03/18/2023] Open
Abstract
Background: This systematic review and meta-analysis (SRMA) aimed to synthesize the current literature on the impacts of adolescent and young adult (AYA, ages 15–39 years) cancer on reproductive health outcomes. Methods: EMBASE and Medline were searched from 1 January 2000 to 26 January 2022 for observational studies that included individuals with AYA cancer and controls which evaluated reproductive health outcomes. We used random effects models and 95% confidence intervals to obtain pooled measures of associations between AYA cancer, cancer treatment, and reproductive health outcomes. Results: The search identified 8625 articles; 21 were included. 62 reproductive outcomes were assessed and classified according to a sex-based framework as fetal/neonatal (n = 26), maternal (n = 11), fetal/neonatal-maternal (n = 23), and maternal-paternal (n = 2). Meta-analyses of crude estimates showed significant associations between AYA cancer and outcomes including preterm birth (pooled odds ratio [pOR] 1.31; 95% CI: 1.22, 1.42), gestational diabetes (pOR 1.43; 95% CI: 1.03, 1.99), and fertility treatment (pOR 2.66; 95% CI 1.71, 4.11). We also found higher odds of preterm birth (pOR 1.65; 95% CI: 1.21, 2.26) and low APGAR score at birth (pOR 2.03; 95% CI: 1.32, 3.13) among AYA cancer patients who received radiation compared to controls. Conclusions: Our SRMA quantified impacts of AYA cancers and treatments on several reproductive health outcomes.

J Natl Cancer Inst 2022; 114:1674-1680. [PMID: 36029247 PMCID: PMC9745431 DOI: 10.1093/jnci/djac168] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Revised: 08/10/2022] [Accepted: 08/25/2022] [Indexed: 01/11/2023] Open
Abstract
BACKGROUND Gonadotoxic effects of cancer treatment may increase risk of adverse birth outcomes in adolescent and young adult (AYA, aged 15-39 years) women diagnosed with cancer. We estimated risk of stillbirth (fetal death of gestational age ≥20 weeks or weighing ≥350 grams) in a population-based sample of AYA women. METHODS AYA women diagnosed with cancer between January 1, 1995, and December 31, 2015, were identified using the Texas Cancer Registry and linked to live birth and fetal death certificates through December 31, 2016. Among AYA women, cumulative incidence of stillbirth was estimated by gestational age, and Poisson regression models identified factors associated with stillbirth. Standardized fetal mortality ratios (SMR) compared the observed fetal mortality rate in AYA women with the expected fetal mortality rate in the general population. RESULTS A total of 11 628 live births and 68 stillbirths occurred to 8402 AYA women after diagnosis. Cumulative incidence of stillbirth in AYA women was 0.70% (95% confidence interval [CI] = 0.51% to 0.96%) at 40 weeks of gestation. Risk of stillbirth was higher among Hispanic (risk ratio [RR] = 2.64, 95% CI = 1.29 to 5.41) and non-Hispanic Black (RR = 4.13, 95% CI = 1.68 to 10.16) women compared with non-Hispanic White women; there was no association with receipt of chemotherapy or time since diagnosis. Age- and race and ethnicity-adjusted fetal mortality rate in AYA women was similar to the general population (SMR = 0.99, 95% CI = 0.77 to 1.26). CONCLUSIONS AYA women may be counseled that overall risk of stillbirth is low, and for most, cancer does not appear to confer additional risk.

Abstract
AIM To provide practice guidelines about fertility preservation (FP) in oncology. METHODS We selected 400 articles after a PubMed review of the literature (1987-2019). RECOMMENDATIONS Any child, adolescent and adult of reproductive age should be informed about the risk of treatment gonadotoxicity. In women, systematically proposed FP counselling between 15 and 38 years of age in case of treatment including bifunctional alkylating agents, above 6 g/m2 cyclophosphamide equivalent dose (CED), and for radiation doses on the ovaries ≥3 Gy. For postmenarchal patients, oocyte cryopreservation after ovarian stimulation is the first-line FP technique. Ovarian tissue cryopreservation should be discussed as a first-line approach in case of treatment with a high gonadotoxic risk, when chemotherapy has already started and in urgent cases. Ovarian transposition is to be discussed prior to pelvic radiotherapy involving a high risk of premature ovarian failure. For prepubertal girls, ovarian tissue cryopreservation should be proposed in the case of treatment with a high gonadotoxic risk. In pubertal males, sperm cryopreservation must be systematically offered to any male who is to undergo cancer treatment, regardless of toxicity. Testicular tissue cryopreservation must be proposed in males unable to cryopreserve sperm who are to undergo a treatment with intermediate or severe risk of gonadotoxicity. In prepubertal boys, testicular tissue preservation is: - recommended for chemotherapy with a CED ≥7500 mg/m2 or radiotherapy ≥3 Gy on both testicles. - proposed for chemotherapy with a CED ≥5.000 mg/m2 or radiotherapy ≥2 Gy. If several possible strategies, the ultimate choice is made by the patient.

J Med Internet Res 2022; 24:e32309. [PMID: 35103615 PMCID: PMC8848247 DOI: 10.2196/32309] [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: 07/22/2021] [Revised: 10/06/2021] [Accepted: 12/08/2021] [Indexed: 11/13/2022] Open
Abstract
Background Being diagnosed with cancer during childhood or adolescence can disrupt important periods in an individual’s physical, psychosocial, and spiritual development and potentially reduce the quality of life (QOL) after treatment. Research is urgently required to improve the QOL for child and adolescent cancer survivors, and it is necessary to analyze the trends in prior research reported in international academic journals to identify knowledge structures. Objective This study aims to identify the main keywords based on network centrality, subgroups (clusters) of keyword networks by using a cohesion analysis method, and the main theme of child and adolescent cancer survivor–related research abstracts through topic modeling. This study also aims to label the subgroups by comparing the results of the cohesion and topic modeling. Methods A text network analysis method and topic modeling were used to explore the main trends in child and adolescent cancer survivor research by structuring a network of keyword (semantic morphemes) co-occurrence in the abstracts of articles published in 5 major web-based databases from 2016 to 2020. A total of 1677 child and adolescent cancer survivor–related studies were used for data analyses. Data selection, processing, and analyses were also conducted. Results The top 5 keywords in terms of degree and eigenvector centrality were risk, control interval, radiation, childhood cancer treatment, and diagnosis. Of the 1677 studies used for data analyses, cluster 1 included 780 (46.51%) documents under risk management, cluster 2 contained 557 (33.21%) articles under health-related QOL and supportive care, and cluster 3 consisted of 340 (20.27%) studies under cancer treatment and complications. Conclusions This study is significant in that it confirms the knowledge structure based on the main keywords and cross-disciplinary trends in child and adolescent cancer survivor research published in the last 5 years worldwide. The primary goal of child and adolescent cancer survivor research is to prevent and manage the various aspects of the problems encountered during the transition to a normal life and to improve the overall QOL. To this end, it is necessary to further revitalize the study of the multidisciplinary team approach for the promotion of age-specific health behaviors and the development of intervention strategies with increased feasibility for child and adolescent cancer survivors.

The Burden of Late Effects and Related Risk Factors in Adolescent and Young Adult Cancer Survivors: A Scoping Review. Cancers (Basel) 2021; 13:cancers13194870.

Abstract
Simple Summary It is unclear what the risk of negative health outcomes is after cancer during adolescence and young adulthood. We conducted a review to understand the risk of second cancers, chronic conditions, and death in adolescent and young adult (AYA) cancer survivors and found factors that increase the risk. In total, 652 studies were identified, of which 106 were included in the review: 23 for second cancers, 34 for chronic conditions, and 54 for deaths. The number of included studies increased over time, from four studies in 2010 to 17 in 2020. The studies found that AYA cancer survivors are at an increased risk of second cancers, chronic conditions, and deaths. In particular, the following factors increased risk: radiation exposure for second cancers; younger attained age and earlier calendar period of diagnosis for chronic conditions; and non-Hispanic Black or Hispanic, low socioeconomic status, and earlier calendar period of diagnosis for deaths. Abstract Risk factors associated with late effects in survivors of adolescent and young adult (AYA) cancer are poorly understood. We conducted a systematic scoping review to identify cohort studies published in English from 2010–2020 that included: (1) cancer survivors who were AYAs (age 15–39 years) at diagnosis and (2) outcomes of subsequent malignant neoplasms (SMNs), chronic conditions, and/or late mortality (>5 years postdiagnosis). There were 652 abstracts identified and, ultimately, 106 unique studies were included, of which 23, 34, and 54 studies related to the risk of SMNs, chronic conditions, and mortality, respectively. Studies investigating late effects among survivors of any primary cancer reported that AYA cancer survivors were at higher risk of SMN, chronic conditions, and all-cause mortality compared to controls. There was an indication that the following factors increased risk: radiation exposure (n = 3) for SMNs; younger attained age (n = 4) and earlier calendar period of diagnosis (n = 3) for chronic conditions; and non-Hispanic Black or Hispanic (n = 5), low socioeconomic status (n = 3), and earlier calendar period of diagnosis (n = 4) for late mortality. More studies including the full AYA age spectrum, treatment data, and results stratified by age, sex, and cancer type are needed to advance knowledge about late effects in AYA cancer survivors.

Allogeneic hematopoietic stem cell transplantation for myelodysplastic syndrome in adolescent and young adult patients. Bone Marrow Transplant 2021; 56:2510-2517. [PMID: 33993196 DOI: 10.1038/s41409-021-01324-8] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2020] [Revised: 04/14/2021] [Accepted: 04/21/2021] [Indexed: 11/08/2022]
Abstract
Allogeneic hematopoietic stem cell transplantation (HSCT) is the only curable treatment option for adolescent and young adult (AYA) patients with myelodysplastic syndrome (MDS). The study aim was to evaluate epidemiological data and identify prognostic factors for AYA patients with MDS undergoing allogeneic HSCT. Here, 645 patients were selected from patients enrolled in a multicenter prospective registry for HSCT from 2000 to 2015. The primary endpoint was 3-year overall survival (OS). Survival rates were estimated using the Kaplan-Meier method. Prognostic factors were identified using the multivariable Cox proportional hazards model. The 3-year OS was 71.2% (95% confidence interval [CI]: 67.4-74.6%). In multivariable analysis, active disease status (adjusted hazard ratio: 1.54, 95% CI: 1.09-2.18, p = 0.016), poor cytogenetic risk (1.62, 1.12-2.36, p = 0.011), poor performance status (2.01, 1.13-3.56, p = 0.016), human leukocyte antigen (HLA)-matched unrelated donors (2.23, 1.39-3.59, p < 0.001), HLA-mismatched unrelated donors (2.16, 1.09-4.28, p = 0.027), and cord blood transplantation (2.44, 1.43-4.17, p = 0.001) were significantly associated with poor 3-year OS. In conclusion, in AYA patients with MDS the 3-year OS following allogeneic HSCT was 71.2%. Active disease status, poor cytogenetic risk, poor performance status, and donor sources other than related donors were associated with poor 3-year OS.

Abstract
Background This study was conducted to evaluate late toxicities in adolescent and young adult (AYA) patients who received photon or proton therapy. Methodology A total of 106 AYA patients who received proton and photon therapy and were followed-up for more than two years were retrospectively evaluated. The median age of patients was 22 years (range, 15-29 years). A total of 47 patients were male and 59 were female. A total of 35 and 71 patients received photon and proton therapy, respectively. All but one patient received radiotherapy with curative intent. The target disease was benign and malignant in 28 and 78 patients, respectively. Results The median follow-up period in all patients was 62 months (range: 24-293 months). Grade 3 or higher toxicity was observed in 20 patients. There was one case of grade 5 toxicity (myelodysplastic syndrome), which was probably due to chemotherapy. No other secondary cancers were observed. Regarding life events, 15 and 88 patients were married and unmarried at the start of radiotherapy, respectively. Of the 88 unmarried patients, five were married after radiotherapy. Occupation and education were evaluated in 71 patients. Of the 71 patients, 33 were students, 21 were employed, and 16 were unemployed. Of the 33 students, eight were employed and 11 were at a higher educational grade after radiotherapy. Of the 21 employed patients, 17 had the same jobs and four had lost their jobs after radiotherapy. For the 16 unemployed patients, all remained unemployed. Conclusions This study is one of the largest studies to focus on life after radiation therapy among AYAs and suggests that cancer treatment has an influence on life events.

Abstract
We reviewed the available animal and human reproductive function studies of recently approved noncytotoxic oncology drugs. We reviewed the oncofertility information in the prescribing information for the US Food and Drug Administration (FDA)-approved products and/or the product information and consumer medicine information for Therapeutic Goods Administration (TGA)-approved drugs of 32 novel oncology drugs approved between 2014 and 2018 in the United States and/or Australia supplemented by a literature review for additional reproductive effects. No human studies were available on the reproductive effects of all 32 drugs. A systematic literature review of animal reproductive toxicity studies provided only very limited data with nine drugs displaying impaired male fertility, three impaired female fertility, and nine producing impaired fertility in both male and female animals. Two drugs in the study are reported to have no demonstrable impact on fertility in animal reproductive toxicity studies and nine are reported to have unknown effects on fertility. Of the 32 newly listed drugs, only 4 had recommendations regarding potential human fertility risks and accordingly advised clinicians about fertility preservation procedures for patients. The lack of human data and limited animal reproductive toxicity data raises concerns about the potential impact of these novel oncology drugs on human fertility and reproductive function. Consequently, adequate oncofertility recommendations, including for fertility preservation procedures, counselling for psychological or cost implications, and future prognosis for fertility are hindered by this paucity of relevant data. More data on human reproductive effects of novel oncology drugs is urgently required to facilitate effective use of the growing array of oncofertility care options available.

Purging human ovarian cortex of contaminating leukaemic cells by targeting the mitotic catastrophe signalling pathway. J Assist Reprod Genet 2021; 38:1571-1588. [PMID: 33725274 PMCID: PMC8266964 DOI: 10.1007/s10815-021-02081-9] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2020] [Accepted: 01/19/2021] [Indexed: 12/18/2022] Open
Abstract
PURPOSE Is it possible to eliminate metastasised chronic myeloid leukaemia (CML) and acute myeloid leukaemia (AML) cells from ovarian cortex fragments by inhibition of Aurora B/C kinases (AURKB/C) without compromising ovarian tissue or follicles? METHODS Human ovarian cortex tissue with experimentally induced tumour foci of CML, AML and primary cells of AML patients were exposed to a 24h treatment with 1 μM GSK1070916, an AURKB/C inhibitor, to eliminate malignant cells by invoking mitotic catastrophe. After treatment, the inhibitor was removed, followed by an additional culture period of 6 days to allow any remaining tumour cells to form new foci. Ovarian tissue integrity after treatment was analysed by four different assays. Appropriate controls were included in all experiments. RESULTS Foci of metastasised CML and AML cells in ovarian cortex tissue were severely affected by a 24h ex vivo treatment with an AURKB/C inhibitor, leading to the formation of multi-nuclear syncytia and large-scale apoptosis. Ovarian tissue morphology and viability was not compromised by the treatment, as no significant difference was observed regarding the percentage of morphologically normal follicles, follicular viability, glucose uptake or in vitro growth of small follicles between ovarian cortex treated with 1 μM GSK1070916 and the control. CONCLUSION Purging of CML/AML metastases in ovarian cortex is possible by targeting the Mitotic Catastrophe Signalling Pathway using GSK1070916 without affecting the ovarian tissue. This provides a therapeutic strategy to prevent reintroduction of leukaemia and enhances safety of autotransplantation in leukaemia patients currently considered at high risk for ovarian involvement.

Abstract
As survival rates in teenagers and young adults diagnosed with haematological malignancies now exceed 70%, it is important that long-term quality of life, including measures to protect future fertility, are considered and discussed with patients and their families. Although discussion on the effect of planned cancer treatment on fertility is standard of care, knowledge of potential fertility treatment options and when they should be offered in haematological malignancies is not always so clear. In each case, the advice on the appropriate preservation of fertility depends upon a complex interplay of factors, weighing out the risk of future infertility against the risk of fertility preservation treatment, and recommendations must be made on a case-by-case basis. The aim of this Review is to evaluate the gonadotoxicity of treatments of prevalent haematological malignancies in teenagers and young adults, and provide an evidence-based framework to help with fertility discussion and management at the time of diagnosis, relapse or resistant disease, and in long-term follow-up settings.

Abstract
While cancer during pregnancy and its treatment has grown to be a popular topic in recent years, little is known on how to advise patients looking to conceive or conceiving after cancer treatment. The aim of this paper is to review the available literature on the impact of pregnancy on survivors of the most common childhood cancers, brain cancer, haematological malignancies, thyroid cancer, melanomas and sarcomas. Its main objective is to be a source of information for clinicians looking to counsel patients in these delicate moments exploiting all the available literature, albeit scarce. Given the available literature, we conclude that the presence of a multidisciplinary team is of great importance in supporting the patient and her loved ones when facing pregnancy with a previous cancer diagnosis.

Looking beyond the ovary for oncofertility care in women: uterine injury as a potential target for fertility-preserving treatments. J Assist Reprod Genet 2020; 37:1467-1476.

Abstract
Treatment for cancer has the potential to significantly diminish fertility and, further, to negatively impact the obstetrical outcomes of pregnancies that do occur. Cancer survivors have decreased rates of fertility and increased rates of pregnancy complications, such as preterm birth and low birth weight, after exposure to chemotherapy. To date, research on the impact of chemotherapy and radiotherapy on fertility and pregnancy outcomes has focused largely on the gonadotoxic effect of cancer treatments on ovaries, while the uterus and endometrium have not been extensively studied. It is intuitive, however, that decreased fertility and poorer obstetrical outcomes may be substantially mediated through injury to a highly mitotic tissue like the endometrium, which is also central to embryo implantation and utero-placental exchange. Pregnancy complications in cancer survivors might be due to compromised blood supply to the endometrium and myometrium affecting placentation or altered remodeling of the pregnant uterus secondary to radiation fibrosis. Alterations in endometrial receptivity at the molecular level could affect pregnancy implantation and early pregnancy loss, but later complications also can occur. This review focuses on understanding the unintended effects of chemotherapy and radiotherapy on uterine function in female cancer survivors and the impact on pregnancy, and summarizes mechanisms to protect and treat the uterus before and after cancer chemotherapy and radiotherapy.
