RESUMO
INTRODUCTION: Children, adolescent, and young adult cancer survivors experience overall increased risks of infertility that are preventable through effective fertility preservation services prior to starting cancer treatment. Oncofertility care is the evidence-based practice of informing newly diagnosed cancer patients about their reproductive risks and supporting shared decision-making on fertility preservation services. Despite longstanding clinical guidelines, oncofertility care delivery continues to be limited and highly variable across adult and pediatric oncology settings. MATERIALS AND METHODS: We describe the design of a stepped wedge cluster randomized clinical trial to evaluate the effectiveness of the multi-component Telehealth Oncofertility Care (TOC) intervention conducted in 20 adult and pediatric oncology clinics across three health systems in Southern California. Intervention components are: 1) electronic health record-based oncofertility needs screen and referral pathway to a virtual oncofertility hub; 2) telehealth oncofertility counseling through the hub; and 3) telehealth oncofertility financial navigation through the hub. We hypothesize the intervention condition will be associated with increased proportions of patients who engage in goal-concordant oncofertility care (i.e., engagement in reproductive risk counseling and fertility preservation services that meet the patient's fertility goals) and improved patient-reported outcomes, compared to the usual care control condition. We will also evaluate intervention implementation in a mixed-methods study guided by implementation science frameworks. DISCUSSION: Our overall goal is to speed implementation of a scalable oncofertility care intervention at cancer diagnosis for children, adolescent and young adult cancer patients to improve their future fertility and quality of life. TRIAL REGISTRATION: Clinicaltrials.gov Identifier: NCT05443737.

OBJECTIVE: To estimate the effect of platinum-based chemotherapy on live birth (LB) and infertility after cancer, in order to address a lack of treatment-specific fertility risks for female survivors of adolescent and young adult cancer, which limits counseling on fertility preservation decisions. DESIGN: Retrospective cohort study. SETTING: US administrative database. PATIENTS: We identified incident breast, colorectal, and ovarian cancer cases in females aged 15-39 years who received platinum-based chemotherapy or no chemotherapy and matched them to females without cancer. INTERVENTION: Platinum-based chemotherapy. MAIN OUTCOME MEASURES: We estimated the effect of chemotherapy on the incidence of LB and infertility after cancer, overall, and after accounting for competing events (recurrence, death, and sterilizing surgeries). RESULTS: There were 1,287 survivors in the chemotherapy group, 3,192 in the no chemotherapy group, and 34,147 women in the no cancer group, with a mean age of 33 years. Accounting for competing events, the overall 5-year LB incidence was lower in the chemotherapy group (3.9%) vs. the no chemotherapy group (6.4%). Adjusted relative risks vs. no chemotherapy and no cancer groups were 0.61 (95% confidence interval [CI] 0.42-0.82) and 0.70 (95% CI 0.51-0.93), respectively. The overall 5-year infertility incidence was similar in the chemotherapy group (21.8%) compared with the no chemotherapy group (20.7%). The adjusted relative risks vs. no chemotherapy and no cancer groups were 1.05 (95% CI 0.97-1.15) and 1.42 (95% CI 1.31-1.53), respectively. CONCLUSIONS: Cancer survivors treated with platinum-based chemotherapy experienced modestly increased adverse fertility outcomes. The estimated effects of platinum-based chemotherapy were affected by competing events, suggesting the importance of this analytic approach for interpretations that ultimately inform clinical fertility preservation decisions.

Survey data from the Mayo Clinic Breast Disease Registry were used to assess fertility counseling and fertility preservation strategies in a modern cohort of young women with breast cancer. One hundred respondents were identified who were under age 50 at the time of breast cancer diagnosis and who expressed interest in future childbearing near the time of diagnosis and/or 1 year later. Ninety-three percent of the 81 respondents to the year one survey recalled fertility counseling prior to cancer treatment. Most who reported a high level of fertility concern declared that this concern had impacted their treatment decisions, often shortening their planned duration of endocrine therapy. Approximately half had taken steps to preserve future fertility, and a third had used a gonadotropin-releasing hormone agonist either alone or combined with another method (e.g., embryo or oocyte cryopreservation).

BACKGROUND: A myriad of federal, state, and organizational policies are designed to improve access to evidence-based healthcare, but the impact of these policies likely varies due to contextual determinants of, reinterpretations of, and poor compliance with policy requirements throughout implementation. Strategies enhancing implementation and compliance with policy intent can improve population health. Critically assessing the multi-level environments where health policies and their related health services are implemented is essential to designing effective policy-level implementation strategies. California passed a 2019 health insurance benefit mandate requiring coverage of fertility preservation services for individuals at risk of infertility due to medical treatments, in order to improve access to services that are otherwise cost prohibitive. Our objective was to document and understand the multi-level environment, relationships, and activities involved in using state benefit mandates to facilitate patient access to fertility preservation services. METHODS: We conducted a mixed-methods study and used the policy-optimized exploration, preparation, implementation, and sustainment (EPIS) framework to analyze the implementation of California's fertility preservation benefit mandate (SB 600) at and between the state insurance regulator, insurer, and clinic levels. RESULTS: Seventeen publicly available fertility preservation benefit mandate-relevant documents were reviewed. Interviews were conducted with four insurers; 25 financial, administrative, and provider participants from 16 oncology and fertility clinics; three fertility pharmaceutical representatives; and two patient advocates. The mandate and insurance regulator guidance represented two "Big P" (system level) policies that gave rise to a host of "little p" (organizational) policies by and between the regulator, insurers, clinics, and patients. Many little p policies were bridging factors to support implementation across levels and fertility preservation service access. Characterizing the mandate's functions (i.e., policy goals) and forms (i.e., ways that policies were enacted) led to identification of (1) intended and unintended implementation, service, and patient outcomes, (2) implementation processes by level and EPIS phase, (3) actor-delineated key processes and heterogeneity among them, and (4) inner and outer context determinants that drove adaptations. CONCLUSIONS: Following the midstream and downstream implementation of a state health insurance benefit mandate, data generated will enable development of policy-level implementation strategies, evaluation of determinants and important outcomes of effective implementation, and design of future mandates to improve fit and fidelity.

Non-invasively evaluating gene expression products in human pre-implantation embryos remains a significant challenge. Here, we develop a non-invasive method for comprehensive characterization of the extracellular RNAs (exRNAs) in a single droplet of spent media that was used to culture human in vitro fertilization embryos. We generate the temporal extracellular transcriptome atlas (TETA) of human pre-implantation development. TETA consists of 245 exRNA sequencing datasets for five developmental stages. These data reveal approximately 4,000 exRNAs at each stage. The exRNAs of the developmentally arrested embryos are enriched with the genes involved in negative regulation of the cell cycle, revealing an exRNA signature of developmental arrest. Furthermore, a machine-learning model can approximate the morphology-based rating of embryo quality based on the exRNA levels. These data reveal the widespread presence of coding gene-derived exRNAs at every stage of human pre-implantation development, and these exRNAs provide rich information on the physiology of the embryo.

Fertility is a top concern for many survivors of cancer diagnosed as children, adolescents and young adults (CAYA). Fertility preservation (FP) treatments are effective, evidence-based interventions to support their family building goals. Fertility discussions are a part of quality oncology care throughout the cancer care continuum. For nearly 2 decades, clinical guidelines recommend counseling patients about the possibility of infertility promptly at diagnosis and offering FP options and referrals as indicated. Multiple guidelines now recommend post-treatment counseling. Infertility risks differ by cancer treatments and age, rendering risk stratification a central part of FP care. To support FP decision-making, online tools for female risk estimation are available. At diagnosis, females can engage in mature oocyte/embryo cryopreservation, ovarian tissue cryopreservation, ovarian suppression with GnRH agonists, in vitro oocyte maturation, and/or conservative management for gynecologic cancers. Post-treatment, several populations may consider undergoing oocyte/embryo cryopreservation. Male survivors' standard of care FP treatments center on sperm cryopreservation before cancer treatment and do not have the same post-treatment indication for additional gamete cryopreservation. In practice, FP care requires systemized processes to routinely screen for FP needs, bridge oncology referrals to fertility, offer timely fertility consultations and access to FP treatments, and support financial navigation. Sixteen US states passed laws requiring health insurers to provide insurance benefits for FP treatments, but variation among the laws and downstream implementation are barriers to accessing FP treatments. To preserve the reproductive futures of CAYA survivors, research is needed to improve risk stratification, FP options, and delivery of FP care.

Importance: Fertility is important to many survivors of adolescent and young adult (AYA) cancer, yet data on this population's fertility perceptions and their alignment with objective infertility risk are scant. Objective: To assess whether estimated treatment gonadotoxicity and posttreatment menstrual pattern are associated with higher infertility risk perception. Design, Setting, and Participants: This retrospective cohort study included female young adult survivors of cancer diagnosed between ages 15 and 39 years were recruited between March 25, 2015, and September 24, 2018, from 2 state cancer registries, social media, and clinician referrals to participate in a study of posttreatment ovarian function. Data analysis occurred between March 1 and September 1, 2022. Exposures: Participants reported their menstrual pattern. Estimated treatment gonadotoxicity was ascertained through medical record review. Main Outcomes and Measures: Participants reported infertility risk perception and were categorized as increased risk (feeling less fertile or unable to become pregnant) or no increased risk (feeling more or as fertile) compared with female individuals their age. Objective infertility risk was determined by estimated gonadotoxicity, menstrual pattern, and ovarian reserve testing of self-collected dried blood spots. Multivariable logistic regression identified factors associated with perceived infertility and underestimation or overestimation of infertility risk. Results: This study included 785 female participants with a mean (SD) age of 33.2 (4.8) years at enrollment and 25.9 (5.7) years at diagnosis. Most participants self-identified their race and ethnicity as White (585 [74.5%]) and non-Hispanic (628 [78.7%]). Most participants (483 [61.5%]) perceived a higher risk of infertility compared with female participants their age. Prior exposure to moderate- or high-gonadotoxicity treatments was associated with higher odds of perceiving increased infertility risk compared with exposure to low-gonadotoxicity treatments (adjusted odds ratio [AOR], 2.73 [95% CI, 1.87-3.97] and 15.39 [95% CI, 5.52-42.96], respectively). Amenorrhea and irregular cycles were associated with higher odds of perceiving increased infertility risk (AOR, 3.98 [95% CI, 2.13-7.41] and 1.69 [95% CI, 1.19-2.40], respectively). Perceived infertility risk had minimal agreement with objective risk (κ = 0.19). Multiparity (AOR, 4.17 [95% CI, 2.61-6.64]) was associated with increased odds of underestimation, while older age (AOR, 0.94 [95% CI, 0.89-0.98]), endocrine comorbidity (AOR, 0.35 [95% CI, 0.18-0.69]), and prior infertility (AOR, 0.16 [95% CI, 0.07-0.38]) were associated with lower odds of underestimation. Multiparity (AOR, 0.48 [95% CI, 0.27-0.86]), breast cancer (AOR, 0.38 [95% CI, 0.20-0.73]), and skin cancer (AOR, 0.24 [95% CI, 0.11-0.51]) were associated with lower odds of overestimation. Conclusions and Relevance: In this cohort study, survivors of AYA cancer had high rates of perceiving increased infertility risk but frequently overestimated or underestimated their risk. These findings suggest that counseling on infertility risk throughout survivorship may reduce misalignment between perceptions and actual risk, decrease fertility-related psychological distress, and inform family planning decisions.

Key Clinical Message: Twin pregnancies in uterine didelphys and uterus bicornuate bicollis represent dicavitary twin pregnancies that can be managed using similar principles. Consideration must be given to delivery planning including mode of delivery and uterine incision. Abstract: Dicavitary twin pregnancies present unique challenges for obstetric management. This case demonstrates an approach to management of a bicornuate bicollis twin pregnancy and provides a contemporary review of the literature on dicavitary twin pregnancies.
RESUMO
INTRODUCTION: From diagnosis to post-treatment, many young breast cancer survivors (YBCS) experience infertility, limited contraception choices, concern about pregnancy safety, and menopausal symptoms. Clinical guidelines recommend oncofertility care (counseling and/or clinical services that meet fertility, contraception, pregnancy health and/or menopausal symptom management needs) throughout the cancer care continuum. However, significant oncofertility care gaps exist in rural, community oncology settings. MATERIALS AND METHODS: We describe the design of an interrupted time series, effectiveness-implementation hybrid clinical trial that evaluates a multi-component intervention to improve YBCS engagement in oncofertility care. The intervention is comprised of 1) oncology clinic-based oncofertility needs screen; 2) a women's health survivorship care plan in Spanish and English; 3) remote patient navigation; and 4) telehealth oncofertility consultation. During the pre-intervention period (12 months), usual care will be delivered. During the intervention period (15 months), the multi-component intervention will be implemented at two rural oncology clinics with largely Latina, Spanish-speaking populations. The primary outcome of YBCS (n = 135) engagement in oncofertility care will be collected from medical record review. We will also collect validated patient-reported outcomes. Informed by the Exploration Preparation Implementation Sustainment (EPIS) implementation science framework, we will integrate qualitative and quantitative data to explore whether and how the intervention was effective, acceptable, appropriate, and delivered with fidelity. DISCUSSION: Our overall goal is to speed implementation of a scalable oncofertility care intervention for YBCS in underserved areas to reduce disparities and improve reproductive health and quality of life. TRIAL REGISTRATION: Clinicaltrials.gov Identifier: NCT05414812.

Purpose: Oncofertility counseling of female cancer patients lacks efficient access to tailored and valid infertility risk estimates to support shared decision-making on fertility preservation treatments. The objective was to develop, conduct user-centered design, and plan clinic-based implementation of the Cancer Related Infertility Score Predictor (CRISP), a web-based tool to support infertility risk counseling. Methods: Using a mixed methods design, literature review was undertaken to abstract data on infertility, primary ovarian insufficiency, and amenorrhea risks of common cancer treatments. The CRISP website was programmed to take user input about patient ages and cancer treatments and generate a risk summary. Using user experience methodology and semistructured interviews, usability testing and implementation assessment were conducted with 12 providers recruited from 5 medical centers in Southern California. Results: The web-based CRISP tool encompasses infertility risk data for 60 treatment regimens among 10 cancer types. Usability testing demonstrated that the tool is intuitive and informed minor modifications, including adding crowd-sourced submission of additional cancer treatments. Participants rated the tool as credible, advantageous over current provider methods to ascertain infertility risks, and useful for tailoring treatment planning and counseling patients. A key barrier was lack of information on some cancer treatments. Fit within clinical workflow was feasible, particularly with electronic health record integration. Conclusions: The novel, web-based CRISP tool is a feasible, acceptable, and appropriate tool to address provider knowledge gap about cancer related infertility risks and use for patient counseling. CRISP has significant potential to support tailored oncofertility counseling in the heterogeneous young cancer patient population.

PURPOSE: Fertility discussions are an integral part of comprehensive care for pediatric, adolescent, and young adult patients newly diagnosed with cancer and are supported by national guidelines. Current institutional practices are poorly understood. METHODS: A cross-sectional survey was distributed to 220 Children's Oncology Group member institutions regarding fertility discussion practices. Descriptive statistics were calculated for all variables. The association between specific practices and selected outcomes on the basis of sex was examined via multivariable logistic regression. RESULTS: One hundred forty-four programs (65.5%) returned surveys. Of these, 65 (45.1%) reported routine discussions of fertility with all female patients and 55 (38.5%) all male patients (P = .25). Ninety-two (63.8%) reported no specific criteria for offering females fertility preservation (FP), compared with 40 (27.7%) for males (P < .001). Program characteristics associated with fertility discussions included reproductive endocrinology and infertility on site (females odds ratio [OR], 2.1; 95% CI, 1.0 to 4.3), discussion documentation mandate (females OR, 2.3; 95% CI, 1.0 to 5.5; males OR, 3.5; 95% CI, 1.4 to 8.7), and cumulative institution-based FP infrastructure (which included [1] routine practice of documentation, [2] template for documentation, [3] mandate for documentation, and [4] availability of FP navigation; females OR, 1.6; 95% CI, 1.1 to 2.3; males OR, 2.3; 95% CI, 1.6 to 3.4). Utilization of practices unsupported by guidelines included offering sperm banking after treatment initiation (39/135 programs; 28.9%), gonadotropin-releasing hormone analogs for ovarian suppression/FP (75/144 programs; 52.1%), ovarian tissue cryopreservation at diagnosis for patients with leukemia (19/64 programs; 29.7%), and testicular tissue cryopreservation (23/138 programs; 16.7%) not part of a clinical trial. CONCLUSION: Despite recommended guidelines, fertility discussions with patients/families before treatment initiation are not routine at Children's Oncology Group institutions. Standard criteria to determine which options should be offered to patients are more common for males than females.

OBJECTIVE: To evaluate risks of preterm birth (PTB) and severe maternal morbidity (SMM) in female survivors of adolescent and young adult cancer and assess maternal comorbidity as a potential mechanism. To determine whether associations differ by use of assisted reproductive technology (ART). DESIGN: Retrospective cohort. SETTING: Commercially insured females in the USA. SAMPLE: Females with live births from 2000-2019 within a de-identified US administrative health claims data set. METHODS: Log-binomial regression models estimated relative risks of PTB and SMM by cancer status and tested for effect modification. Causal mediation analysis evaluated the proportions explained by maternal comorbidity. MAIN OUTCOME MEASURES: PTB and SMM. RESULTS: Among 46 064 cancer survivors, 2440 singleton births, 214 multiple births and 2590 linked newborns occurred after cancer diagnosis. In singleton births, the incidence of PTB was 14.8% in cancer survivors versus 12.4% in females without cancer (aRR 1.19, 95% CI 1.06-1.34); the incidence of SMM was 3.9% in cancer survivors versus 2.4% in females without cancer (aRR 1.44, 95% CI 1.13-1.83). Cancer survivors had more maternal comorbidities before and during pregnancy; 26% of the association between cancer and PTB and 30% of the association between cancer and SMM was mediated by maternal comorbidities. Tests for effect modification of cancer status on perinatal outcomes by ART were non-significant. CONCLUSIONS: Preterm birth and SMM risks were modestly increased after cancer. Significant proportions of elevated risks may result from increased comorbidities. ART did not significantly modify the association between adolescent and young adult cancer and adverse perinatal outcomes. The prevention and treatment of comorbidities provides an opportunity to improve perinatal outcomes among cancer survivors.

Purpose: Oncofertility care for pediatric, adolescent, and young adult cancer patients remains under-implemented across adult and pediatric oncology settings. We pilot tested an electronic health record (EHR)-enabled multicomponent oncofertility intervention (including screening, referral, and fertility consult) in an adult academic oncology program and systematically assessed intervention fit to pediatric and community oncology programs. Methods: Using surveys (n = 33), audits (n = 143), and interviews (n = 21) guided by implementation science frameworks, we pilot tested the EHR-enabled intervention for oncofertility care in young cancer patients at an adult oncology program and evaluated implementation outcomes. We interviewed health care providers from seven regional oncology and fertility programs about intervention fit to their clinical contexts. Results: We recruited 33 health care providers from an adult oncology setting and 15 health care providers from seven additional oncology and fertility settings. At the adult oncology setting, the intervention was found to be appropriate, acceptable, and feasible and improved the screening of fertility needs (from 30% pre- to 51% post-intervention); yet, some patients did not receive appropriate referrals to fertility consults. Providers across all settings suggested content and context modifications, such as adding options to the intervention or allowing the screening component to pop up at a second visit, to improve and adapt the intervention to better fit their clinical care contexts. Conclusions: We found that the EHR-enabled intervention increased the rate of goal-concordant oncofertility care delivery at an adult oncology program. We also identified facilitators, barriers, and needed adaptations to the intervention required for implementation and scaling-up across diverse oncology settings.

PURPOSE: Pregnancy intentions are associated with preconception health behaviors but are understudied among female adolescent and young adult (AYA) cancer survivors. Preconception health is critical for survivors because they face unique risks to fertility and pregnancy from late effects of cancer treatments. This study prospectively assessed the effect of pregnancy intention on physical activity (PA) and smoking behaviors among female AYA survivors. METHODS: A cohort of 1049 female AYA survivors were recruited between 2013 and 2017. Participants were 18-39 years and had completed primary cancer treatment. Longitudinal mixed effects analysis was conducted on participants who completed at least 2 of 4 questionnaires over 1.5 years. Two measures were used to capture multiple dimensions of pregnancy intention. The pregnancy intention score (PIS) captured wanting and planning dimensions and represented a scaled response of low to high intention. The trying dimension captured urgent intention and ranged from not trying, ambivalent (neither attempting nor avoiding pregnancy), and trying now. Intention change was assessed between each consecutive time points. Final analysis was conducted with multiple imputations. RESULTS: Survivors with increased intention measured by trying was associated with increased PA over time (adjusted B [95%CI]: 0.3 [0.01, 0.5]) compared to survivors with no changes or decreased trying intention. PIS was not significantly associated with preconception behaviors. No measure of intention was associated with smoking behavior. CONCLUSIONS: Increasingly urgent pregnancy intention (trying dimension) was associated with higher preconception PA. IMPLICATIONS FOR CANCER SURVIVORS: Screening for immediate intentions can identify AYA survivors in need of early preconception health promotion.

OBJECTIVE: To compare antimüllerian hormone (AMH) patterns by cancer status and treatment exposures across 6 years after incident breast cancer using administrative data. DESIGN: In a cross-sectional design, AMH levels in patients who developed incident breast cancer between ages 15-39 years during 2005-2019 were matched 1:10 to levels in females without cancer in the OptumLabs Data Warehouse. Modeled AMH patterns were compared among cyclophosphamide-based chemotherapy, non-cyclophosphamide-based chemotherapy, no chemotherapy, and no breast cancer groups. SETTING: Commercially insured females in the United States. PATIENT(S): Females with and without breast cancer. EXPOSURE(S): Breast cancer, cyclophosphamide- and non-cyclophosphamide-based chemotherapy. MAIN OUTCOME MEASURE(S): AMH levels. RESULT(S): A total of 233 patients with breast cancer (mean age, 34 years; standard deviation, 3.7 years) contributed 278 AMH levels over a median of 2 years (range, 0-6.7 years) after diagnosis; 52% received cyclophosphamide-based chemotherapy, 17% received non-cyclophosphamide-based chemotherapy (80% platinum-based), and 31% received no chemotherapy. A total of 2,777 matched females without cancer contributed 2,780 AMH levels. The pattern of AMH levels differed among the 4 groups. Among females without cancer and breast cancer survivors who did not undergo chemotherapy, AMH declined linearly over time. In contrast, among those who received cyclophosphamide-based and noncyclophosphamide-based chemotherapy, a nonlinear pattern of AMH level of initial fall during chemotherapy, followed by an increase over 2-4 years, and then by a plateau over 1-2 years before a decline was observed. CONCLUSION(S): In breast cancer survivors, AMH levels from administrative data supported ovarian toxicity of non-cyclophosphamide-based chemotherapy in breast cancer and efficiently depicted the timing and duration of changes in ovarian reserve to reflect the residual reproductive lifespan.

BACKGROUND: Female adolescent and young adult (AYA) cancer survivors face higher infertility and pregnancy risks than peers with no cancer history. Preconception health behaviors such as physical activity (PA), tobacco smoking, and alcohol intake influence reproductive outcomes. In general populations, pregnancy intention is positively associated with healthy preconception behaviors, but it has not been studied among AYA survivors. The authors hypothesized that higher pregnancy intention would be associated with healthier behaviors, especially among AYA survivors with perceived infertility risk. METHODS: A cross-sectional analysis was conducted with data collected between 2013 and 2017 from 1071 female AYA survivors aged 18 to 39 years who had completed their primary cancer treatment and enrolled in an ovarian function study. Self-reported intention dimensions were measured as a pregnancy intention score (PIS) and trying now to become pregnant. Multivariable linear (PA), binary (smoking), and ordinal (alcohol use) logistic regressions were used to estimate associations between intentions and preconception behaviors, with adjustments made for demographic and cancer characteristics. Effect modification by perceived infertility risk was assessed. RESULTS: The mean PIS was 1.1 (SD, 0.77) on a 0 to 2 scale (2 = high intention), and 8.9% were attempting pregnancy now. A higher PIS was associated with increased PA (ß, 0.08; 95% CI, 0.11-1.04), whereas ambivalence in pregnancy intention was associated with lower alcohol consumption (odds ratio, 0.72; 95% CI, 0.55-0.95). Pregnancy intentions were not associated with smoking. Perceived infertility risk strengthened the relationship between PIS and PA (P < .05). CONCLUSIONS: Pregnancy intentions were associated with some healthier preconception behaviors in AYA survivors. Medical professionals caring for AYA survivors may consider pregnancy intention screening to guide conversations on preconception health.
