A comprehensive pediatric cardio-oncology program: a single institution approach to cardiovascular care for pediatric patients with cancer and childhood cancer survivors.

Cardiovascular complications related to cancer therapies are broad and variable in onset. These complications are the leading cause of non-cancer related morbidity and mortality in childhood cancer survivors and can also impact ongoing cancer treatment. Despite this understanding, dedicated cardio-oncology programs are lacking in pediatric cardiology. In an attempt to respond to these concerns, a risk-stratified, comprehensive cardio-oncology program was established to address the cardiovascular needs including prevention, early diagnosis, and management of patients with and at risk for cardiovascular complications of cancer therapy. This manuscript describes a single institution's experience of building and managing a multidisciplinary pediatric cardio-oncology program with close collaboration among cardiologists, oncologists, advanced cardiology and oncology practice providers, and allied health providers such as a dietitian and psychologist to provide comprehensive cardiovascular care for childhood cancer patients and survivors. In developing this program, emphasis was on the childhood cancer survivor population, as various cardiovascular complications can present many years after cancer treatment.

Association of platinum-based chemotherapy with live birth and infertility in female survivors of adolescent and young adult cancer.

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.

Improving vitamin D testing and supplementation in children with newly diagnosed cancer: A quality improvement initiative at Rady Children's Hospital San Diego.

BACKGROUND: Vitamin D deficiency and insufficiency have been associated with poorer health outcomes. Children with cancer are at high risk for vitamin D deficiency and insufficiency. At our institution, we identified high variability in vitamin D testing and supplementation in this population. Of those tested, 65% were vitamin D deficient/insufficient. We conducted a quality improvement (QI) initiative with aim to improve vitamin D testing and supplementation among children aged 2-18 years with newly diagnosed cancer to ≥80% over 6 months. METHODS: An inter-professional team reviewed baseline data, then developed and implemented interventions using Plan-Do-Study-Act (PDSA) cycles. Barriers were identified using QI tools, including lack of automated triggers for testing and inconsistent supplementation criteria and follow-up testing post supplementation. Interventions included an institutional vitamin D guideline, clinical decision-making tree for vitamin D deficiency, insufficiency and sufficiency, electronic medical record triggers, and automated testing options. RESULTS: Baseline: N = 26 patients, four (15%) had baseline vitamin D testing; two (8%) received appropriate supplementation. Postintervention: N = 33 patients; 32 (97%) had baseline vitamin D testing; 33 (100%) received appropriate supplementation and completed follow-up testing timely (6-8 weeks post supplementation). Change was sustained over 24 months. CONCLUSIONS: We achieved and sustained our aim for vitamin D testing and supplementation in children with newly diagnosed cancer through inter-professional collaboration of hematology/oncology, endocrinology, hospital medicine, pharmacy, nursing, and information technology. Future PDSA cycles will address patient compliance with vitamin D supplementation and impact on patients' vitamin D levels.

Psychosocial stress and ovarian function in adolescent and young adult cancer survivors.

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.

Mental Health Outcomes in Adolescent and Young Adult Female Cancer Survivors of a Sexual Minority.

Purpose: Sexual minority (SM) individuals experience higher rates of anxiety and depression. Previous research on mental health disparities for SM cancer survivors has largely focused on adult survivors; however, studies are limited in the adolescent and young adult (AYA) population. This study's objective is to compare depression and anxiety symptoms between AYA, female cancer survivors who identify as an SM and those who identify as heterosexual. Methods: A cross-sectional analysis of 1025 AYA survivors aged 18-40 years (2015-2017) was performed. Patients self-reported SM identification and depression and anxiety symptoms, as measured by the Patient Health Questionnaire (PHQ8) and Generalized Anxiety Disorder Scale (GAD7), respectively. Multivariable logistic regression tested associations between SM identification and depression and anxiety. Results: Sixty-four participants (6%) identified as an SM. In adjusted analyses, SM participants had 1.88 higher odds of anxiety (odds ratio [OR] 1.88, confidence interval [95% CI] 1.05-3.35, p = 0.033) compared with heterosexual participants. SM participants did not have significantly higher odds of depression (OR 1.36, CI 0.75-2.47, p = 0.31). More social support was significantly associated with lower odds of depression (OR 0.91, CI 0.89-0.93, p < 0.001) and anxiety (OR 0.93, CI 0.91-0.94, p < 0.001). Conclusions: AYA cancer survivors identifying as an SM had nearly twice the odds of anxiety, with social support that is protective for both anxiety and depression. While mental health screening is recommended throughout the cancer care continuum, these data support the need for reliable screening, clinician awareness of increased vulnerability in the AYA, SM survivor population, and clinician training on culturally competent care and generation of evidence-based interventions.

Reproductive intentions in childless female adolescent and young adult cancer survivors.

OBJECTIVE: To examine the association between prior cancer treatments, medical comorbidities, and voluntary childlessness in reproductive-age women who are survivors of cancers diagnosed as adolescents and young adults (AYA survivors). DESIGN: Cross-sectional analysis. SETTING: Participants were recruited from California and Texas cancer registries, fertility preservation programs, and cancer advocacy groups. PATIENT(S): Women (n = 413) ages 18-40 who were diagnosed with cancer between ages 15 and 35, completed primary cancer treatments, had at least one ovary, and were nulliparous. INTERVENTION(S): Cancer treatment gonadotoxicity and medical comorbidities. MAIN OUTCOME MEASURE(S): Voluntary childlessness. RESULT(S): The mean age of survivors was 31.8 years (SD, 4.9) with a mean of 6.5 years (SD, 4.4) since cancer diagnosis. Breast (26%), thyroid (19%), and Hodgkin lymphoma (18%) were the most common cancers. Twenty-two percent of the cohort was voluntarily childless. Medical comorbidities, cancer diagnosis, prior surgery, prior chemotherapy, and prior gonadotoxic treatments were not significantly associated with voluntary childlessness. In adjusted analysis, survivors of older reproductive age (adjusted odds ratio = 2.97 [1.71-5.18]) and nonheterosexual participants (adjusted odds ratio = 4.71 [2.15-10.32]) were more likely to report voluntary childlessness. CONCLUSION(S): A moderate proportion of AYA cancer survivors are voluntarily childless, but reproductive intentions were not related to cancer type or cancer treatments. AYA survivors of older age and nonheterosexual identification were more likely to be voluntarily childless. These data support assessing reproductive intentions and tailoring reproductive care such as fertility and contraception counseling that is appropriate for a survivor's intentions.

Hematologic Manifestations of Nutritional Deficiencies: Early Recognition is Essential to Prevent Serious Complications.

Nutritional deficiencies, including deficiencies of vitamin B12, copper, and vitamin C, may result in cytopenias and hematologic symptoms. Early recognition of these deficiencies is imperative for prompt treatment and improvement in hematologic and other manifestations. We describe 5 cases which illustrate the hematologic manifestations of nutritional deficiencies and challenges to initial diagnosis and management. Supplementation of the deficient vitamin or micronutrient in all of these cases resulted in rapid resolution of cytopenias, hemorrhage, and other associated hematologic symptoms. We also review other nutritional deficiencies that manifest with hematologic symptoms and compile recommendations on treatment and expected time to response.

Fertility counseling before cancer treatment and subsequent reproductive concerns among female adolescent and young adult cancer survivors.

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.

Pregnancy and child health outcomes in pediatric and young adult leukemia and lymphoma survivors: a systematic review.

As long-term survival is high for children and young adults diagnosed with leukemia and lymphoma, delineating maternal, fetal and offspring health risks is important to their family planning. This systematic review examined data comparing these health risks between leukemia and lymphoma survivors and women without a history of cancer. Following a search of Embase, PubMed, CINAHL, Cochrane, and Web of Science, 142 articles were screened and 18 were included in this review. No higher risks of spontaneous abortion, maternal diabetes and anemia, stillbirth, birth defects, or childhood cancer in offspring were observed in survivors compared to controls. Important to counseling and clinical care, live birth rates were lower, while preterm birth and low birth weight risks were modestly higher in survivors compared to controls. Findings were largely reassuring but highlight the lack of data on maternal cardiopulmonary risks, differential risk by cancer treatment type, and interventions to decrease these risks.

Age and Cancer Treatment Are Related to Receiving Treatment Summaries and Survivorship Care Plans in Female Young Adult Cancer Survivors.

The study determined factors associated with patient-reported receipt of survivorship care plans and/or treatment summaries (SCP/TS). Two hundred forty female young adult cancer survivors ages 18-44 completed a web-based survey that included self-report on receiving SCP/TS. Mean age was 32.8 (standard deviation 5.8) years; 20% were diagnosed with cancer at age <21. Only 47% reported receipt of SCP/TS. Age <21 at diagnosis (odds ratio [OR] 2.0, 95% confidence interval [CI] 1.0-3.9), chemotherapy (OR 2.3, 95% CI 1.2-4.6), central nervous system radiation (OR 2.5, 95% CI 1.1-5.6), and bone marrow transplantation (OR 7.2, 95% CI 1.5-33.3) were significantly associated with higher odds of SCP/TS receipt. Improved integration of TS and SCP into cancer survivorship care is needed.
