RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Extracellular RNAs (exRNAs) are present in human serum. It remains unclear to what extent these circulating exRNAs may reflect human physiologic and disease states. Here, we developed SILVER-seq (Small Input Liquid Volume Extracellular RNA Sequencing) to efficiently sequence both integral and fragmented exRNAs from a small droplet (5 µL to 7 µL) of liquid biopsy. We calibrated SILVER-seq in reference to other RNA sequencing methods based on milliliters of input serum and quantified droplet-to-droplet and donor-to-donor variations. We carried out SILVER-seq on more than 150 serum droplets from male and female donors ranging from 18 y to 48 y of age. SILVER-seq detected exRNAs from more than a quarter of the human genes, including small RNAs and fragments of mRNAs and long noncoding RNAs (lncRNAs). The detected exRNAs included those derived from genes with tissue (e.g., brain)-specific expression. The exRNA expression levels separated the male and female samples and were correlated with chronological age. Noncancer and breast cancer donors exhibited pronounced differences, whereas donors with or without cancer recurrence exhibited moderate differences in exRNA expression patterns. Even without using differentially expressed exRNAs as features, nearly all cancer and noncancer samples and a large portion of the recurrence and nonrecurrence samples could be correctly classified by exRNA expression values. These data suggest the potential of using exRNAs in a single droplet of serum for liquid biopsy-based diagnostics.

RESUMEN

STUDY QUESTION: Is psychosocial stress associated with ovarian function in reproductive-aged survivors of cancer diagnosed as adolescents and young adults (AYA survivors)? SUMMARY ANSWER: We observed no association between self-reported and biomarkers of psychosocial stress and ovarian function in AYA survivors. WHAT IS KNOWN ALREADY: Psychosocial stress suppresses hypothalamic-pituitary-ovarian axis, resulting in ovulatory dysfunction, decreased sex steroidogenesis and lower fertility in reproductive-aged women. Many cancer survivors experience high psychosocial stress and hypothalamic-pituitary-adrenal axis dysregulation. The menstrual pattern disturbances and infertility they experience have been attributed to ovarian follicle destruction, but the contribution of psychosocial stress to these phenotypes is unknown. STUDY DESIGN, SIZE, DURATION: A cross-sectional study was conducted estimating the association between perceived stress, measured by self-report and saliva cortisol, and ovarian function, measured by bleeding pattern, dried blood spot (DBS) FSH and LH, and saliva estradiol. We included 377 AYA survivor participants. PARTICIPANTS/MATERIALS, SETTING, METHODS: AYA survivor participants were ages 15-35 at cancer diagnosis and ages 18-40 at study enrollment, had completed primary cancer treatment, had a uterus and at least one ovary, did not have uncontrolled endocrinopathy and were not on hormone therapy. Recruited from cancer registries, physician referrals and cancer advocacy groups, participants provided self-reported information on psychosocial stress (Perceived Stress Scale-10 (PSS-10)) and on cancer and reproductive (fertility, contraception, menstrual pattern) characteristics. DBS samples were collected timed to the early follicular phase (cycle Days 3-7) for menstruating individuals and on a random day for amenorrheic individuals; saliva samples were collected three time points within 1 day. FSH and LH were measured by DBS ELISAs, cortisol was measured by ELISA and estradiol was measured by liquid chromatography tandem mass spectrometry. MAIN RESULTS AND THE ROLE OF CHANCE: The median age of participants was 34.0 years (range 19-41) at a median of 6.0 years since cancer diagnosis. The most common cancer was breast (32.1%). Median PSS-10 score was 15 (range 0-36), with 5.3% scoring ≥26, the cut point suggestive of severe stress. Cortisol levels followed a diurnal pattern and cortisol AUC was negatively correlated with PSS-10 scores (P = 0.03). Neither PSS-10 scores nor cortisol AUC were associated with FSH, LH, estradiol levels or menstrual pattern. Waking and evening cortisol and the cortisol awakening response also were not related to ovarian function measures. LIMITATIONS, REASONS FOR CAUTION: Our analysis is limited by its cross-sectional nature, heterogeneity of cancer diagnosis and treatments and low prevalence of severe stress. WIDER IMPLICATIONS OF THE FINDINGS: The lack of association between psychosocial stress and a variety of ovarian function measures in female AYA cancer survivors suggests that psychosocial stress does not have a significant impact on the reproductive axis of AYA survivors. This finding is important in counseling this population on their menstrual pattern and family building plans.

RESUMEN

Cyclophosphamide is associated with chemotherapy-related ovarian failure (CROF) in breast cancer survivors, however little is known about predicting individual risks. We sought to identify genetic alleles as biomarkers for risk of CROF after cyclophosphamide treatment. One hundred fifteen premenopausal women with newly diagnosed breast cancer were genotyped for single nucleotide polymorphisms (SNPs) in genes involved in cyclophosphamide activation (CYP3A4 and CYP2C19) and detoxification (GSTP1 and GSTA1). Patients prospectively completed menstrual diaries. With median follow up of 808 days, 28% experienced CROF. Survivors homozygous for the GSTA1 minor allele had lower hazards for developing CROF (HR 0.22 [95% CI 0.05-0.94], p=.04), while survivors homozygous for the CYP2C19 minor allele had higher hazards for developing CROF (HR 4.5 [95% CI 1.5-13.4], p=.007) compared to patients with at least one major allele. In separate multivariable models adjusting for age and tamoxifen use, the associations were no longer statistically significant (GSTA1 HR 0.24 [95% CI 0.06-1.0], p=.05; CYP2C19 HR 2.5 [0.8-7.6], p=.11). CYP3A4 and GSTP1 SNPs were not significantly related to CROF. In younger breast cancer survivors undergoing cyclophosphamide-based chemotherapy, genetic variation in CYP2C19 and GSTA1 merits further study to determine its relationship with CROF.IMPACT STATEMENTWhat is already known on this subject? Young breast cancer survivors face important potential implications of chemotherapy-related ovarian failure (CROF). Little is known about individual risk for CROF. Cyclophosphamide, a particularly gonadotoxic drug commonly used in breast cancer treatment, is metabolised by various cytochrome p450 enzymes. Studies have shown genetic variation in p450 enzymes is associated with differential clinical outcomes after cyclophosphamide treatment: breast cancer patients homozygous for GSTA1 minor allele had improved overall survival; lupus patients homozygous for CYP2C19 minor allele had increased risk for CROF; and CYP3A4*1B I was associated with decreased risk for CROF.What do the results of this study add? We show a surprising opposite trend for the risk of CROF in breast cancer patients with GSTA1 and CYP2C19 variants, while we did not show a significant risk for genetic variation in CYP3A4 (which had previously been shown to have a protective effect) or GSTP1.What are the implications of these findings for clinical practice and/or further research? This study shows the complexity of genetic variation in predicting outcomes to treatment. We advocate for future replicative studies to potentially validate GSTA1 and CYP2C19 and definitively negate CYP3A4 and GSTP1 as biomarkers for risk of CROF after cyclophosphamide treatment. Understanding genetic variation in chemotherapy metabolism has the potential to individualise treatment regimens to maximise efficacy and minimise toxicity.

RESUMEN

BACKGROUND: Adjuvant tamoxifen reduces the risk of breast cancer recurrence in women with oestrogen receptor-positive breast cancer. Tamoxifen also increases the risk of postmenopausal bleeding, endometrial polyps, hyperplasia, and endometrial cancer. The levonorgestrel-releasing intrauterine system (LNG-IUS) causes profound endometrial suppression. This systematic review considered the evidence that the LNG-IUS prevents the development of endometrial pathology in women taking tamoxifen as adjuvant endocrine therapy for breast cancer. OBJECTIVES: To determine the effectiveness and safety of the levonorgestrel intrauterine system (LNG-IUS) in pre- and postmenopausal women taking adjuvant tamoxifen following breast cancer for the outcomes of endometrial and uterine pathology including abnormal vaginal bleeding or spotting, and secondary breast cancer events. SEARCH METHODS: We searched the following databases on 29 June 2020; The Cochrane Gynaecology and Fertility Group specialised register, Cochrane Central Register of Controlled Trials, MEDLINE, Embase, PsycINFO and Cumulative Index to Nursing and Allied Health Literature. We searched the Cochrane Breast Cancer Group specialised register on 4 March 2020. We also searched two trials registers, checked references for relevant trials and contacted study authors and experts in the field to identify additional studies. SELECTION CRITERIA: We included randomised controlled trials (RCTs) of women with breast cancer on adjuvant tamoxifen that compared the effectiveness of the LNG-IUS with endometrial surveillance versus endometrial surveillance alone on the incidence of endometrial pathology. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures recommended by Cochrane. The primary outcome measure was endometrial pathology (including polyps, endometrial hyperplasia, or endometrial cancer), diagnosed at hysteroscopy or endometrial biopsy. Secondary outcome measures included fibroids, abnormal vaginal bleeding or spotting, breast cancer recurrence, and breast cancer-related deaths. We rated the overall certainty of evidence using GRADE methods. MAIN RESULTS: We included four RCTs (543 women analysed) in this review. We judged the certainty of the evidence to be moderate for all of the outcomes, due to imprecision (i.e. limited sample sizes and low event rates). In the included studies, the active treatment arm was the 20 µg/day LNG-IUS plus endometrial surveillance; the control arm was endometrial surveillance alone. In tamoxifen users, the LNG-IUS probably reduces the incidence of endometrial polyps compared to the control group over both a 12-month period (Peto odds ratio (OR) 0.22, 95% confidence interval (CI) 0.08 to 0.64, I² = 0%; 2 RCTs, n = 212; moderate-certainty evidence) and over a long-term follow-up period (24 to 60 months) (Peto OR 0.22, 95% CI 0.13 to 0.39; I² = 0%; 4 RCTs, n = 417; moderate-certainty evidence). For long-term follow-up, this suggests that if the incidence of endometrial polyps following endometrial surveillance alone is assumed to be 23.5%, the incidence following LNG-IUS with endometrial surveillance would be between 3.8% and 10.7%.  The LNG-IUS probably slightly reduces the incidence of endometrial hyperplasia compared with controls over a long-term follow-up period (24 to 60 months) (Peto OR 0.13, 95% CI 0.03 to 0.67; I² = 0%; 4 RCTs, n = 417; moderate-certainty evidence). This suggests that if the chance of endometrial hyperplasia following endometrial surveillance alone is assumed to be 2.8%, the chance following LNG-IUS with endometrial surveillance would be between 0.1% and 1.9%. However, it should be noted that there were only six cases of endometrial hyperplasia. There was insufficient evidence to reach a conclusion regarding the incidence of endometrial cancer in tamoxifen users, as no studies reported cases of endometrial cancer. At 12 months of follow-up, the LNG-IUS probably increases abnormal vaginal bleeding or spotting compared to the control group (Peto OR 7.26, 95% CI 3.37 to 15.66; I² = 0%; 3 RCTs, n = 376; moderate-certainty evidence). This suggests that if the chance of abnormal vaginal bleeding or spotting following endometrial surveillance alone is assumed to be 1.7%, the chance following LNG-IUS with endometrial surveillance would be between 5.6% and 21.5%. By 24 months of follow-up, abnormal vaginal bleeding or spotting occurs less frequently than at 12 months of follow-up, but is still more common in the LNG-IUS group than the control group (Peto OR 2.72, 95% CI 1.04 to 7.10; I² = 0%; 2 RCTs, n = 233; moderate-certainty evidence). This suggests that if the chance of abnormal vaginal bleeding or spotting following endometrial surveillance alone is assumed to be 4.2%, the chance following LNG-IUS with endometrial surveillance would be between 4.4% and 23.9%. By 60 months of follow-up, there were no cases of abnormal vaginal bleeding or spotting in either group. The numbers of events for the following outcomes were low: fibroids (n = 13), breast cancer recurrence (n = 18), and breast cancer-related deaths (n = 16). As a result, there is probably little or no difference in these outcomes between the LNG-IUS treatment group and the control group.  AUTHORS' CONCLUSIONS: The LNG-IUS probably slightly reduces the incidence of benign endometrial polyps and endometrial hyperplasia in women with breast cancer taking tamoxifen. At 12 and 24 months of follow-up, the LNG-IUS probably increases abnormal vaginal bleeding or spotting among women in the treatment group compared to those in the control. Data were lacking on whether the LNG-IUS prevents endometrial cancer in these women. There is no clear evidence from the available RCTs that the LNG-IUS affects the risk of breast cancer recurrence or breast cancer-related deaths. Larger studies are necessary to assess the effects of the LNG-IUS on the incidence of endometrial cancer, and to determine whether the LNG-IUS might have an impact on the risk of secondary breast cancer events.

RESUMEN

BACKGROUND: Fertility counseling before cancer treatment has been advocated by clinical guidelines, though little is known about its long-term impact on the unique reproductive concerns of female adolescent and young adult (AYA) cancer survivors. The goal of this study was to measure the association between fertility counseling by fertility specialists before cancer treatment and subsequent reproductive concerns. METHOD: A cross-sectional analysis was performed among 747 AYA survivors aged 18-40 years who had been recruited from cancer registries and physician and advocacy group referrals between 2015 and 2017. Participants self-reported information on past fertility counseling at cancer diagnosis, cancer type and treatment, and current reproductive concerns, as measured using the multidimensional Reproductive Concerns After Cancer scale. Multivariable log-binomial regression models tested associations between fertility counseling and reproductive concerns. RESULTS: The mean age of the cohort was 33.0 years (standard deviation, 5.1 years), and the mean period since diagnosis was 7.7 years (standard deviation, 5.0 years). Seventy-three percent of participants were white, and 24% were Hispanic. Fertility counseling was reported by 19% of survivors; moderate to high overall reproductive concerns were reported by 44% of participants. In adjusted analysis, fertility counseling was significantly associated with moderate to high reproductive concerns (risk ratio, 1.22; 95% confidence interval, 1.02-1.45) and not modified by exposure to fertility-threatening treatments (Pinteraction = .23). CONCLUSION: A large proportion of AYA cancer survivors across cancer types and treatment exposures reported moderate to high reproductive concerns, suggesting that there is a need to address these cancer-specific reproductive health concerns after treatment. Higher concerns, even with counseling, suggests the need to improve the quality of fertility counseling throughout the cancer continuum.

RESUMEN

OBJECTIVE: The objective of this study was to examine the association between theoretical constructs from the Health Belief Model and fertility consultation status after cancer. METHODS: Reproductive-aged female cancer survivors self-reported their use of fertility consultation, perceived severity of and susceptibility to infertility, perceived barriers to and effectiveness of fertility consultation, and cues to action from family/peers and doctors, as well as demographics and cancer characteristics. Logistic regression was used to analyze the association between theoretical constructs and fertility consultation status. RESULTS: Fertility consultation uptake was more prevalent among survivors with higher incomes, those without children, those who wanted a (another) child, and those who were diagnosed more recently. In the final multivariate model, higher perceived severity of infertility, fewer perceived barriers to fertility consultation, and more cues to action from family/peers and doctors were significantly associated with fertility consultation uptake, controlling for income. Exploratory bivariate analyses of barriers to fertility consultation revealed that cost and trouble accessing services were significantly associated with not having a fertility consultation. CONCLUSIONS: The Health Belief Model is useful for understanding factors associated with fertility consultation uptake. Efforts should be made to reduce financial barriers and improve patient-centered assessment of family-building goals.

RESUMEN

OBJECTIVE: The aims of this study were to examine the factor structure and reliability of the multidimensional Reproductive Concerns After Cancer (RCAC) scale in a sample of female cancer survivors during their reproductive years, younger than age 45. METHODS: Female reproductive-aged survivors (N = 238; current age, 18 to 44 y) with a variety of cancer diagnoses completed a web-based survey that included the RCAC scale. Three structural models were examined via confirmatory factor analysis: (a) one-factor, (b) higher-order with one second-order factor and six first-order factors, and (c) oblique six-factor. Reliability was examined using omega total and Revelle omega total. RESULTS: Only the oblique six-factor model of the RCAC scale fits well. Omega total and Revelle omega total estimates for all of the six three-item subscales were in the nearly satisfactory to good range (.66 to.87). CONCLUSIONS: The RCAC scale was found to have satisfactory factor structure and reliability when measuring a range of reproductive concerns experienced by female reproductive-aged survivors. The RCAC scale is a multidimensional measure of varying aspects of reproductive concerns, and results suggest that the scale may be best represented as a profile of subscale scores. The subscale scores would be useful for tailoring recommendations and interventions to more effectively address the diverse reproductive concerns of female reproductive-aged survivors.

RESUMEN

PURPOSE: The aim of this study was to evaluate the prevalence of menopausal symptoms in young cancer survivors immediately following the completion of chemotherapy. METHODS: This prospective cohort study followed 124 young females with a new diagnosis of cancer requiring chemotherapy to assess symptoms of menopause before treatment and immediately following chemotherapy. Symptoms were compared before and after treatment using the McNemar test and between cancer patients and 133 similar-aged healthy controls using Pearson χ2 and Fisher's exact tests. RESULTS: Participants undergoing cancer therapy reported more menopausal symptoms compared to controls prior to the initiation of any treatment (hot flashes or night sweats 33 vs. 7%, p < 0.01, trouble sleeping 57 vs. 31%, p < 0.01, headaches 50 vs. 35%, p = 0.02, and decreased libido 36 vs. 16%, p < 0.01) and also reported a greater prevalence of symptoms immediately after cancer therapy compared to pretreatment prevalence (vasomotor symptoms, p < 0.01, vaginal dryness, p < 0.01, decreased concentration, p < 0.01, and body aches, p = 0.01). Cancer patients with lower anti-Müllerian hormone (AMH) levels after treatment (<0.10 ng/mL) had an increased risk of vasomotor symptoms (OR 2.2, p = 0.04), mood swings (OR 2.4, p = 0.03), feeling sad (OR 2.2, p = 0.04), trouble sleeping (OR 2.7, p = 0.02), and decreased libido (OR 3.0, p = 0.03) when controlled for age and cancer type, and the incidence of these symptoms was not affected by the use of systemic hormones or psychiatric medications. Treatment length, use of alkylating agents, pelvic radiation, and marital status were also not associated with the prevalence of menopausal symptoms. CONCLUSIONS: Premenopausal women with a new cancer diagnosis have more menopausal symptoms than females of similar age before and after cancer treatment, the effects of which are not mitigated by systemic hormone use. Decreased AMH levels were associated with an increased likelihood of reporting physiologic symptoms after therapy. IMPLICATIONS FOR CANCER SURVIVORS: This information is imperative for counseling; ultimately, improved symptom management during and after cancer therapies will improve quality of life in young cancer survivors.

RESUMEN

The link between autoimmune diseases and primary immunodeficiency syndromes has been increasingly appreciated. Immunologic evaluation of a young man with autoimmune enterocolopathy and unexplained infections revealed evidence of immunodeficiency, including IgG subclass deficiency, impaired Ag-induced lymphocyte proliferation, reduced cytokine production by CD8(+) T lymphocytes, and decreased numbers of NK cells. Genetic evaluation identified haploinsufficiency of NFAT5, a transcription factor regulating immune cell function and cellular adaptation to hyperosmotic stress, as a possible cause of this syndrome. Inhibition or deletion of NFAT5 in normal human and murine cells recapitulated several of the immune deficits identified in the patient. These results provide evidence of a primary immunodeficiency disorder associated with organ-specific autoimmunity linked to NFAT5 deficiency.

RESUMEN

PURPOSE: The purpose of the present study is to investigate factors associated with female young adult cancer survivors' (YCSs) use of fertility care (FC), including consultation or fertility treatment, after completing their cancer treatment. METHODS: In this cross-sectional study, females between that ages of 18 and 35 years who had been diagnosed with childhood, adolescent, or young adult cancers completed a 20-min web-based survey that included demographics, reproductive history, use of FC, fertility-related informational needs, and reproductive concerns. RESULTS: A total of 204 participants completed the survey. Participants' mean age was 28.3 ± 4.5 years. Thirty (15 %) participants reported using FC after cancer treatment. The majority of participants recalled not receiving enough information about fertility preservation options at the time of cancer diagnosis (73 %). In multivariable analysis, those with higher concerns about having children because of perceived risk to their personal health (P = 0.003) were less likely to report use of FC after cancer treatment. Those who had used FC before cancer treatment (P = 0.003) and who felt less fertile than age-matched women (P = 0.02) were more likely to use FC after their cancer treatment. CONCLUSIONS: While most YCSs in this cohort believed that they did not receive enough information about fertility and most wanted to have children, the vast majority did not seek FC. The findings of this study offer further evidence of the need for improved education and emotional support regarding reproductive options after cancer treatment is completed. Targeted discussions with YCSs about appropriate post-treatment FC options may improve providers' capacity to help YCSs meet their parenthood goals.

RESUMEN

PURPOSE: Factors that differentially regulate oocyte and granulosa cell growth within the early preantral follicle and how these factors differ at each stage of follicle growth remain poorly understood. The aim of this study was to isolate and evaluate the effect of recombinant growth and differentiation factor 9 (GDF9) on oocyte and granulosa cell growth at the primary and early secondary stages of preantral follicle growth during in vitro culture. METHODS: Primary stage follicles (diameters of 50-89 µm) and early secondary stage follicles (diameters of 90-120 µm) were isolated from immature mice, and individual, intact follicles were cultured in vitro in the presence and absence of recombinant GDF9. The effects of GDF9 on follicle growth were determined by the assessment of changes in the follicle volume during culture. The growth of the granulosa cell and oocyte compartments of the follicles was evaluated separately at each stage. RESULTS: GDF9 significantly increased the growth of isolated follicles at both the primary and early secondary follicle stages. Independent evaluation of the granulosa cell and oocyte compartments revealed that, while GDF9 promoted granulosa cell growth at both stages of folliculogenesis, oocyte growth was stage specific. GDF9 promoted growth of the oocyte at the primary, but not the early secondary, follicle stage. CONCLUSIONS: These findings demonstrate a stage-specific role for GDF9 in the regulation of oocyte and granulosa cell growth at the primary and early secondary stages of preantral follicle development.

RESUMEN

BACKGROUND: Young adult female cancer survivors have unmet reproductive concerns and informational needs that are associated with poorer quality of life. The purpose of this study was to examine the association between current reproductive concerns and moderate to severe depression among young survivors. METHODS: This cross-sectional study included 200 female cancer survivors between the ages of 18 and 35 years who completed a Web-based survey measuring reproductive history, parenthood desires, reproductive concerns after cancer, and quality-of-life indicators. RESULTS: The mean age of the participants was 28 years (standard deviation, 4.4 years), and almost two-thirds were diagnosed within 5 years of survey completion. A multivariate logistic regression analysis controlling for education, duration of survivorship, and social support revealed an association between experiencing reproductive concerns and moderate to severe depression (odds ratio for each 5-unit increase in the Reproductive Concerns After Cancer [RCAC] score, 1.30; 95% confidence interval, 1.06-1.60). Among those with moderate to severe depression, 23% had high RCAC scores, whereas 6% of those with minimal to mild depression did (P < .001). CONCLUSIONS: A higher level of reproductive concerns was associated with greater odds of experiencing moderate to severe depression. Almost a quarter of survivors in this sample reported moderate to severe depression, and addressing reproductive concerns represents one potential area of intervention for improving the psychosocial health of young survivors.

RESUMEN

BACKGROUND: Adjuvant tamoxifen reduces the risk of breast cancer recurrence in women with oestrogen receptor-positive breast cancer. Tamoxifen also increases the risk of postmenopausal bleeding, endometrial polyps, hyperplasia, and endometrial cancer. The levonorgestrel-releasing intrauterine system (LNG-IUS) causes profound endometrial suppression. This systematic review considered the evidence that the LNG-IUS prevents the development of endometrial pathology in women taking tamoxifen as adjuvant endocrine therapy for breast cancer. OBJECTIVES: To determine the effectiveness and safety of levonorgestrel intrauterine system (LNG-IUS) in pre- and postmenopausal women taking adjuvant tamoxifen following breast cancer for the outcomes of endometrial and uterine pathology including abnormal vaginal bleeding or spotting, and secondary breast cancer events. SEARCH METHODS: We searched the following databases: Cochrane Menstrual Disorders and Subfertility Group Specialised Register (MDSG), Cochrane Breast Cancer Group Specialised Register (CBCG), Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Database of Abstracts of Reviews of Effects (DARE), The Cochrane Library, clinicaltrials.gov, The World Health Organisation International Trials Registry, ProQuest Dissertations & Theses, MEDLINE, EMBASE, CINAHL (Cumulative Index to Nursing and Allied Health Literature), PsycINFO, Web of Science, OpenGrey, LILACS, PubMed, and Google. The final search was performed in October 2015. SELECTION CRITERIA: Randomised controlled trials of women with breast cancer on adjuvant tamoxifen that compared endometrial surveillance alone (control condition) versus the LNG-IUS with endometrial surveillance (experimental condition) on the incidence of endometrial pathology. DATA COLLECTION AND ANALYSIS: Study selection, risk of bias assessment and data extraction were performed independently by two review authors. The primary outcome measure was endometrial pathology (including polyps, endometrial hyperplasia, or endometrial cancer) diagnosed at hysteroscopy or endometrial biopsy. Secondary outcome measures included fibroids, abnormal vaginal bleeding or spotting, breast cancer recurrence, and breast cancer-related deaths. The overall quality of evidence was rated using GRADE methods. MAIN RESULTS: Four randomised controlled trials involving 543 women were identified and are included in this review. In the included studies, the active treatment arm was the 20 µg/day levonorgestrel-releasing intrauterine system (LNG-IUS) plus endometrial surveillance; the control arm was endometrial surveillance alone. In tamoxifen users, the LNG-IUS led to a reduction in the incidence of endometrial polyps over both a 12-month period (Peto OR 0.22, 95% CI 0.08 to 0.64, 2 studies, n = 212, I² = 0%) and over a long-term follow-up period (24 to 60 months) (Peto OR 0.22, 95% CI 0.13 to 0.39, 4 studies, n = 417, I² = 0%, moderate quality evidence). Also the LNG-IUS led to a reduction in the incidence of endometrial hyperplasia over a long-term follow-up period (24 to 60 months) (Peto OR 0.13, 95% CI 0.03 to 0.67, four studies, n = 417, I² = 0%, moderate quality evidence). However, it should be noted that the number of events of endometrial hyperplasia was low (n = 6). None of the trials were sufficiently powered to detect whether LNG-IUS leads to significant changes in the incidence of endometrial cancer in tamoxifen users. At 12 months of follow-up abnormal vaginal bleeding or spotting was more common in the LNG-IUS treatment group (Peto OR 7.26, 95% CI 3.37 to 15.66, 3 studies, n = 376, I² = 0%, moderate quality evidence). By 24 months of follow-up, abnormal vaginal bleeding or spotting occurred less frequently compared to 12 months of follow-up in the LNG-IUS treatment group but was still more common than the control group (Peto OR 2.72, 95% CI 1.04 to 7.10, 2 studies, n = 233, I² = 0%, moderate quality evidence). By 60 months of follow-up, no cases of abnormal vaginal bleeding or spotting were reported in either group. The numbers of events for the following outcomes were low: fibroids (n = 13), breast cancer recurrence (n = 18), and breast cancer-related deaths (n = 16). There was no evidence of a difference between the LNG-IUS treatment group and controls for these outcomes. The quality of the evidence was judged as moderate, due to limited sample sizes and low event rates for the outcome comparisons. AUTHORS' CONCLUSIONS: The LNG-IUS reduces the incidence of benign endometrial polyps and endometrial hyperplasia in women with breast cancer taking tamoxifen. At 12 and 24 months of follow-up, the LNG-IUS increased abnormal vaginal bleeding or spotting among women in the treatment group compared to those in the control. There is no clear evidence from the available randomised controlled trials that the LNG-IUS prevents endometrial cancer in these women. There is no clear evidence from the available randomised controlled trials that the LNG-IUS affects the risk of breast cancer recurrence or breast cancer-related deaths. Larger studies are necessary to assess the effects of the LNG-IUS on the incidence of endometrial cancer, and to determine whether the LNG-IUS might have an impact on the risk of secondary breast cancer events.
