Abstract Background Skin cancer is the most common secondary malignancy among young adult childhood cancer survivors (YA‐CCS). Skin examination to detect skin cancer early (including melanoma as well as basal or squamous cell skin cancers), both physician‐based (PSE) and self‐skin exam (SSE), is recommended, particularly for radiotherapy‐exposed YA‐CCS who are at high risk of developing skin cancer. Methods Awareness and prevalence of skin examination and demographic, clinical, and healthcare correlates were examined in a population‐based sample of YA‐CCS with diverse cancer types excluding melanoma. Descriptive frequencies and logistic regression models were conducted using sample weights to correct for non‐response bias with PSE, SSE and adherence to both as outcomes. Results The sample comprised 1064 participants with 53% Latino. Eight percent of participants were aware of the need for skin examination; 9% reported receipt of PSE within past 2 years; 35% reported regular SSE; and 6% were adherent to both. Among the radiotherapy‐treated, 10% were aware of the need for skin examination, 10% reported recent PSE; 38% reported regular SSE; and 8% were adherent to both. Healthcare and clinical factors including healthcare self‐efficacy, engagement in cancer‐related follow‐up care, greater treatment intensity and greater number of treatment‐related late effects were positively associated with PSE and SSE. Latino YA‐CCS were less likely to engage in PSE and SSE. Conclusion(s) Adherence to recommended screening for skin cancer was low in this at‐risk population, notably for YA‐CCS exposed to radiotherapy. The development of effective strategies to expand skin cancer screening is needed in this at‐risk population.

Abstract Background There is substantial heterogeneity in symptom management provided to pediatric patients with cancer. The primary objective was to describe the adaptation process and specific adaptation decisions related to symptom management care pathways based on clinical practice guidelines. The secondary objective evaluated if institutional factors were associated with adaptation decisions. Methods Fourteen previously developed symptom management care pathway templates were reviewed by an institutional adaptation team composed of two clinicians at each of 10 institutions. They worked through each statement for all care pathway templates sequentially. The institutional adaptation team made the decision to adopt, adapt or reject each statement, resulting in institution-specific symptom management care pathway drafts. Institutional adaption teams distributed the 14 care pathway drafts to their respective teams; their feedback led to care pathway modifications. Results Initial care pathway adaptation decision making was completed over a median of 4.2 (interquartile range 2.0-5.3) weeks per institution. Across all institutions and among 1350 statements, 551 (40.8%) were adopted, 657 (48.7%) were adapted, 86 (6.4%) were rejected and 56 (4.1%) were no longer applicable because of a previous decision. Most commonly, the reason for rejection was not agreeing with the statement (70/86, 81.4%). Institutional-level factors were not significantly associated with statement rejection. Conclusions Acceptability of the 14 care pathways was evident by most statements being adopted or adapted. The adaptation process was accomplished over a relatively short timeframe. Future work should focus on evaluation of care pathway compliance and determination of the impact of care pathway-consistent care on patient outcomes.

Abstract Adolescent and young adult (AYA) enrollment in cancer clinical trials (CCT) is suboptimal. Few studies have explored site level barriers and facilitators to AYA enrollment on CCTs and the efficacy of interventions to enhance enrollment. A cross sectional survey was developed by the COG AYA Oncology Discipline Committee Responsible Investigator (RI) Network to identify perceived barriers and facilitators to enrollment, as well as opportunities to improve enrollment. Associations of barriers and facilitators to enrollment with program demographics were assessed. The survey was sent to all AYA RI Network members (n = 143) and quantitative and thematic analyses were conducted. The overall response rate was 42% (n = 60/143). Participants represented diverse institutions based on size, presence or absence of dedicated AYA programs, and proximity and relationship between pediatric and medical oncology practices within the institution. The most frequently cited barriers to enrolling AYAs in CCTs were administrative logistical issues (45%), disparate enrollment practices (42%) and communication issues (27%) between pediatric and medical oncology and perceived limited trial availability (27%). The most frequently reported facilitators to enrollment included having strong communication between pediatric and medical oncology (48%), having a supportive research infrastructure (35%) and the presence of AYA champions (33%). Many barriers and facilitators were similar across institutions and AYA program types. Shared barriers and facilitators to AYA CCT enrollment exist across the landscape of cancer care settings. Interventions aimed at increasing coordination between pediatric and medical oncology clinical trials offices and providers have high potential to improve site-level AYA enrollment.

Childhood cancer survivor transition qualitative parent ,Neoplasms. Tumors. Oncology. Including cancer and carcinogens ,RC254-282 - Abstract
Abstract Background Survivor‐focused care for adolescent and young adult (AYA) childhood cancer survivors (CCS) often involves their parents. Recognizing the importance of parents in the ongoing care of CCS, our study sought to identify key aspects of a successful transition for CCS from pediatric‐ to adult‐centered care from the parent perspective. Methods We conducted qualitative interviews with 26 parents of CCS who were receiving care in the long‐term follow‐up (LTFU) clinic at a single institution. We used a semi‐structured interview protocol with the parents and conducted a thematic content analysis. Results Using a constant comparison approach, data revealed three primary themes regarding parents’ perspectives toward ensuring a seamless transition from pediatric‐ to adult‐centered follow‐up care: (1) the transition needs to include seamless communication between all involved parties, (2) survivors need to demonstrate sufficient health care self‐efficacy in order to achieve a successful transition, and (3) the survivor‐focused care should include support for survivors’ overall well‐being, including financial and health insurance literacy. Conclusions For parents of AYA CCS, the optimal pediatric to adult care transition model should include mechanisms that facilitate communication between parents, CCS, and survivor‐focused providers while also supporting self‐efficacy and financial literacy as it relates to health insurance.

Abstract Background Sexual health (SH) is an important concern for adolescents and young adults (AYAs). This study determined current SH communication practices, barriers, and additional resources needed among pediatric oncology clinicians who treat AYAs. Methods A cross‐sectional survey was developed by the Children's Oncology Group (COG) AYA Committee and sent to pediatric oncologists (n = 1,987; 85.9%) and advanced practice providers (APPs, n = 326; 14.1%) at 226 COG institutions. Responses were tabulated and compared using tests of proportion and trend. Results The sample comprised 602 respondents from 168 institutions and was proportionally representative (468 oncologists [77.7%], 76 APPs [12.6%], 58 unidentified [9.6%]; institutional and provider response rates 74.3% and 26.2%, respectively). Almost half of respondents (41.7%) reported no/small role in SH care. Medical topics were discussed most often, including contraception (67.2%), puberty (43.5%), and sexual activity (37.5%). Topics never/rarely discussed included gender identity (64.5%), sexual orientation (53.7%), and sexual function (50.3%). Frequently cited communication barriers included lack of time, low priority, perceived patient discomfort, and the presence of a parent/guardian. Respondents endorsed the need for further education/resources on sexual function (66.1%), gender identity/sexual orientation (59.5%), and body image (46.6%). Preferred education modalities included dissemination of published guidelines (64.7%), skills training modules (62.9%), and webinars (45.3%). By provider type, responses were similar overall but differed for perception of role, barriers identified, and resources desired. Conclusions Many pediatric oncology clinicians play minimal roles in SH care of AYAs and most SH topics are rarely discussed. Provider‐directed education/training interventions have potential for improving SH care of AYA cancer patients.

ABSTRACT Background Radiation‐related screening guidelines for survivors of childhood cancer currently use irradiated regions (IR) to determine risk for late effects. However, contemporary radiotherapy techniques utilize volumetric dosimetry (VD) to determine organ‐specific exposures, which could inform need for late effect surveillance. Methods This cross‐sectional cohort study involved patients treated for cancer using computerized tomography‐planned irradiation at Children's Hospital Los Angeles from 2000–2016. Organs at risk were identified using both VD and IR. Under each method, Children's Oncology Group Long‐Term Follow‐Up Guidelines were applied to determine radiation‐related potential late effects and their correlative recommended screening practices. Patients served as their own controls. Mean number of potential late effects per patient and recommended screening practices per patient per decade of follow‐up were compared using paired t‐tests; comparisons were adjusted for diagnosis and gender using random effects, repeated measure linear regression. Results In this cohort (n = 132), median age at end of treatment was 10.6 years (range, 1.4–20.4). Brain tumor was the most common diagnosis (45%) and head/brain the most common irradiated region (61%). Under IR and VD, the mean number of potential late effects flagged was 24.4 and 21.7, respectively (−11.3%, p

Childhood cancer survivor transition qualitative ,Neoplasms. Tumors. Oncology. Including cancer and carcinogens ,RC254-282 - Abstract
Abstract Background Adolescent and young adult (AYA) childhood cancer survivors (CCS) should be empowered to continue their survivor-focused care as they transition into adult medicine. However, the majority of AYA-aged survivors become lost to follow up around the age of typical transition to adulthood. The purpose of this study was to identify, from the patient’s perspective, key factors that facilitate successful transitions to adult-centered survivorship care. Methods A qualitative study was conducted with AYA CCS (n = 29) from the survivorship clinic of a single institution as key informants. Data were collected through a series of structured phone interviews and subjected to thematic content analysis. Results Four major themes with multiple subthemes were identified: (1) transition practices need to be flexible and individually tailored; (2) effective communication is critical to a successful transition; (3) continuity in providers is needed during the transition; and (4) comprehensive care means care that also addresses psycho-social well-being. Conclusions From the perspective of AYA CCS, the ideal model of transitional survivorship care could include a patient navigator who promotes provider flexibility, consistent communication, and pro-active comprehensive care that encompasses both medical and psycho-social well-being. Models of care for CCS should be built to provide, or seamlessly facilitate, continuous survivor-focused care across the age continuum. A longitudinal relationship with a survivor-focused provider can help promote the values that CCS’ report as important in transitioning care from pediatric- to adult-centered care.

Abstract Background Few adolescents and young adults (AYAs, 15‐39 years old) enroll onto cancer clinical trials, which hinders research otherwise having the potential to improve outcomes in this unique population. Prior studies have reported that AYAs are more likely to receive cancer care in community settings. The National Cancer Institute (NCI) has led efforts to increase trial enrollment through its network of NCI‐designated cancer centers (NCICC) combined with community outreach through its Community Clinical Oncology Program (CCOP; replaced by the NCI Community Oncology Research Program in 2014). Methods Using AYA proportional enrollment (the proportion of total enrollments who were AYAs) as the primary outcome, we examined enrollment of AYAs onto SWOG therapeutic trials at NCICC, CCOP, and non‐NCICC/non‐CCOP sites from 2004 to 2013 by type of site, study period (2004‐08 vs 2009‐13), and patient demographics. Results Overall, AYA proportional enrollment was 10.1%. AYA proportional enrollment decreased between 2004‐2008 and 2009‐2013 (13.1% vs 8.5%, P

Abstract Cisplatin is an essential chemotherapeutic agent in the treatment of many pediatric cancers. Unfortunately, cisplatin‐induced hearing loss (CIHL) is a common, clinically significant side effect with life‐long ramifications, particularly for young children. ACCL05C1 and ACCL0431 are two recently completed Children’s Oncology Group studies focused on the measurement and prevention of CIHL. The purpose of this paper was to gain insights from ACCL05C1 and ACCL0431, the first published cooperative group studies dedicated solely to CIHL, to inform the design of future pediatric otoprotection trials. Use of otoprotective agents is an attractive strategy for preventing CIHL, but their successful development must overcome a unique constellation of methodological challenges related to translating preclinical research into clinical trials that are feasible, evaluate practical interventions, and limit risk. Issues particularly important for children include use of appropriate methods for hearing assessment and CIHL severity grading, and use of trial designs that are well‐informed by preclinical models and suitable for relatively small sample sizes. Increasing interest has made available new funding opportunities for expanding this urgently needed research.

Medicine - Abstract
OBJECTIVES/SPECIFIC AIMS: Low cancer clinical trial (CCTs) enrollment may contribute to the poor survival improvement for adolescents and young adults (AYAs, aged 15–39 years) with cancer. Treatment site is thought to exacerbate this problem. This study evaluated whether differences in CCT availability explain lower CCT enrollment depending on treatment site for AYAs. METHODS/STUDY POPULATION: This prospective, observational cohort study was conducted at an academic children’s hospital and an adult cancer hospital, 2 affiliated sites within a NCI-designated Comprehensive Cancer Center over 13 months. In consecutive AYA patients newly diagnosed with cancer at both site, it was determined whether an appropriate CCT existed nationally, was available locally, and if enrollment occurred. The proportions of AYAs in these categories were compared by site using the χ2 test. RESULTS/ANTICIPATED RESULTS: Among 152 consecutive AYA patients, 68 and 84 were treated at the children’s hospital and adult cancer hospital, respectively. AYAs treated at the children’s hospital had similar CCT existence nationally compared with AYAs treated at the adult hospital [36/68 (52.9%) vs. 45/84 (53.6%), p=0.938]. However, a significantly higher percentage of children’s hospital treated AYAs than adult hospital treated AYAs had an available CCT [30/68 (44.1%) vs. 14/84 (16.7%), p

Cancer Research ,Oncology - Abstract
Purpose: Cisplatin-induced hearing loss (CIHL) is common and permanent. As compared with earlier otoprotectants, we hypothesized N-acetylcysteine (NAC) offers potential for stronger otoprotection through stimulation of glutathione (GSH) production. This study tested the optimal dose, safety, and efficacy of NAC to prevent CIHL. Patients and Methods: In this nonrandomized, controlled phase Ia/Ib trial, children and adolescents newly diagnosed with nonmetastatic, cisplatin-treated tumors received NAC intravenously 4 hours post-cisplatin. The trial performed dose-escalation across three dose levels to establish a safe dose that exceeded the targeted peak serum NAC concentration of 1.5 mmol/L (as identified from preclinical models). Patients with metastatic disease or who were otherwise ineligible were enrolled in an observation-only/control arm. To evaluate efficacy, serial age-appropriate audiology assessments were performed. Integrated biology examined genes involved in GSH metabolism and post-NAC GSH concentrations. Results: Of 52 patients enrolled, 24 received NAC and 28 were in the control arm. The maximum tolerated dose was not reached; analysis of peak NAC concentration identified 450 mg/kg as the recommended phase II dose (RP2D). Infusion-related reactions were common. No severe adverse events occurred. Compared with the control arm, NAC decreased likelihood of CIHL at the end of cisplatin therapy [OR, 0.13; 95% confidence interval (CI), 0.021–0.847; P = 0.033] and recommendations for hearing intervention at end of study (OR, 0.082; 95% CI, 0.011–0.60; P = 0.014). NAC increased GSH; GSTP1 influenced risk for CIHL and NAC otoprotection. Conclusions: NAC was safe at the RP2D, with strong evidence for efficacy to prevent CIHL, warranting further development as a next-generation otoprotectant.

PURPOSE For survivors of childhood cancer treated with doxorubicin, dexrazoxane is cardioprotective for at least 5 years. However, longer-term data are lacking. METHODS Within the Children's Oncology Group and the Dana Farber Cancer Institute's Childhood Acute Lymphoblastic Leukemia Consortium, we evaluated four randomized trials of children with acute lymphoblastic leukemia or Hodgkin lymphoma, who received doxorubicin with or without dexrazoxane, and a nonrandomized trial of patients with osteosarcoma who all received doxorubicin with dexrazoxane. Cumulative doxorubicin doses ranged from 100 to 600 mg/m2 across these five trials, and dexrazoxane was administered uniformly (10:1 mg/m2 ratio) as an intravenous bolus before doxorubicin. Cardiac function was prospectively assessed in survivors from these trials, plus a matched group of survivors of osteosarcoma treated with doxorubicin without dexrazoxane. Two-dimensional echocardiograms and blood biomarkers were analyzed centrally in blinded fashion. Multivariate analyses adjusted for demographic characteristics, cumulative doxorubicin dose, and chest radiotherapy determined the differences and associations by dexrazoxane status. RESULTS From 49 participating institutions, 195 participants were assessed at 18.1 ± 2.7 years since cancer diagnosis (51% dexrazoxane-exposed; cumulative doxorubicin dose 297 ± 91 mg/m2). Dexrazoxane administration was associated with superior left ventricular fractional shortening (absolute difference, +1.4% [95% CI, 0.3 to 2.5]) and ejection fraction (absolute difference, +1.6% [95% CI, 0.0 to 3.2]), and lower myocardial stress per B-type natriuretic peptide (–6.7 pg/mL [95% CI, –10.6 to –2.8]). Dexrazoxane was associated with a reduced risk of having lower left ventricular function (fractional shortening < 30% or ejection fraction < 50%; odds ratio, 0.24 [95% CI, 0.07 to 0.81]). This protective association was primarily seen in those treated with cumulative doxorubicin doses ≥ 250 mg/m2. CONCLUSION Among young adult-aged survivors of childhood cancer, dexrazoxane was associated with a cardioprotective effect nearly 20 years after initial anthracycline exposure.

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.

PURPOSE: Young adult childhood cancer survivors (YACCSs) are often impacted by cancer-related cognitive impairment (CRCI) and psychological distress. Using the Project Forward Cohort, we evaluated the relationship between CRCI and substance use behaviors. METHODS: YACCSs were surveyed between 2015 and 2018 (N = 1,106, female = 50.8%, Hispanic = 51.5%, median age = 25.5 years). Associations between CRCI and substance use (tobacco, binge drinking, marijuana, prescription drug misuse, and e-cigarette/vaporizer) were examined in multivariate logistic or log-binomial regressions, adjusting for child at diagnosis (0-14 years), years since diagnosis, sex, race/ethnicity, cancer type, and treatment intensity. Mediation analysis was performed to determine opportunities for interventions. RESULTS: CRCI was reported by 144 (13.0%) survivors. The highest prevalence was observed in CNS cancers (25.4%) and leukemia (13.3%) survivors. After covariate adjustment, CRCI was associated with 2.26 times the odds of prior 30-day vaping (95% CI, 1.24 to 4.11; P = .007). Mediators with significant indirect effects in the CRCI-vaping relationship include depressive symptoms (Center for Epidemiological Studies Depression Scale) and having two or more cancer-related late effects ( P < .05). CONCLUSION: CRCI among YACCSs was associated with reports of vaping. Oncologists should screen for vaping behavior if CRCI is apparent. Increasing access to long-term follow-up clinics, addressing physical and mental health issues, and monitoring and educating on vaping and other substance use behaviors is recommended to improve the long-term health of YACCSs.

Background Advancements in treatment and supportive care have led to improved survival for adolescents and young adults (AYAs) with cancer; however, a subset of those diagnosed remain at risk for early death (within 2 months of diagnosis). Factors that place AYAs at increased risk of early death have not been well studied. Methods The Surveillance, Epidemiology, and End Results registry was used to assess risk of early death in AYAs with hematologic malignancies, central nervous system tumors, and solid tumors. Associations between age at diagnosis, sex, race, ethnicity, socioeconomic status, insurance status, rurality, and early death were assessed. Results A total of 268 501 AYAs diagnosed between 2000 and 2016 were included. Early death percentage was highest in patients diagnosed with hematologic malignancies (3.1%, 95% confidence interval [CI] = 2.9% to 3.2%), followed by central nervous system tumors (2.5%, 95% CI = 2.3% to 2.8%), and solid tumors (1.0%, 95% CI = 0.9% to 1.0%). Age at diagnosis, race, ethnicity, lower socioeconomic status, and insurance status were associated with increased risk of early death in each of the cancer types. For AYAs with hematologic malignancies and solid tumors, risk of early death decreased statistically significantly over time. Conclusions A subset of AYAs with cancer remains at risk for early death. In addition to cancer type, sociodemographic factors also affect risk of early death. A better understanding of the interplay of factors related to cancer type, treatment, and health systems that place certain AYA subsets at higher risk for early death is needed to address these disparities and improve outcomes.

Skin cancer is the most common secondary malignancy among young adult childhood cancer survivors (YA-CCS). Skin examination to detect skin cancer early (including melanoma as well as basal or squamous cell skin cancers), both physician-based (PSE) and self-skin exam (SSE), is recommended, particularly for radiotherapy-exposed YA-CCS who are at high risk of developing skin cancer.Awareness and prevalence of skin examination and demographic, clinical, and healthcare correlates were examined in a population-based sample of YA-CCS with diverse cancer types excluding melanoma. Descriptive frequencies and logistic regression models were conducted using sample weights to correct for non-response bias with PSE, SSE and adherence to both as outcomes.The sample comprised 1064 participants with 53% Latino. Eight percent of participants were aware of the need for skin examination; 9% reported receipt of PSE within past 2 years; 35% reported regular SSE; and 6% were adherent to both. Among the radiotherapy-treated, 10% were aware of the need for skin examination, 10% reported recent PSE; 38% reported regular SSE; and 8% were adherent to both. Healthcare and clinical factors including healthcare self-efficacy, engagement in cancer-related follow-up care, greater treatment intensity and greater number of treatment-related late effects were positively associated with PSE and SSE. Latino YA-CCS were less likely to engage in PSE and SSE.Adherence to recommended screening for skin cancer was low in this at-risk population, notably for YA-CCS exposed to radiotherapy. The development of effective strategies to expand skin cancer screening is needed in this at-risk population.

- Abstract
Purpose:Cisplatin-induced hearing loss (CIHL) is common and permanent. As compared with earlier otoprotectants, we hypothesized N-acetylcysteine (NAC) offers potential for stronger otoprotection through stimulation of glutathione (GSH) production. This study tested the optimal dose, safety, and efficacy of NAC to prevent CIHL.Patients and Methods:In this nonrandomized, controlled phase Ia/Ib trial, children and adolescents newly diagnosed with nonmetastatic, cisplatin-treated tumors received NAC intravenously 4 hours post-cisplatin. The trial performed dose-escalation across three dose levels to establish a safe dose that exceeded the targeted peak serum NAC concentration of 1.5 mmol/L (as identified from preclinical models). Patients with metastatic disease or who were otherwise ineligible were enrolled in an observation-only/control arm. To evaluate efficacy, serial age-appropriate audiology assessments were performed. Integrated biology examined genes involved in GSH metabolism and post-NAC GSH concentrations.Results:Of 52 patients enrolled, 24 received NAC and 28 were in the control arm. The maximum tolerated dose was not reached; analysis of peak NAC concentration identified 450 mg/kg as the recommended phase II dose (RP2D). Infusion-related reactions were common. No severe adverse events occurred. Compared with the control arm, NAC decreased likelihood of CIHL at the end of cisplatin therapy [OR, 0.13; 95% confidence interval (CI), 0.021–0.847; P = 0.033] and recommendations for hearing intervention at end of study (OR, 0.082; 95% CI, 0.011–0.60; P = 0.014). NAC increased GSH; GSTP1 influenced risk for CIHL and NAC otoprotection.Conclusions:NAC was safe at the RP2D, with strong evidence for efficacy to prevent CIHL, warranting further development as a next-generation otoprotectant.

Background: Childhood cancer survivors are at risk for cardiovascular disease. We assessed the burden of potentially modifiable cardiometabolic risk factors (CRF) among survivors compared with population-matched controls. Methods: Survivors previously enrolled on Pediatric Oncology Group protocols 9404, 9425, 9426, 9754, and Dana-Farber Cancer Institute 95-01 from 1996 to 2001 with acute lymphoblastic leukemia/lymphoma, Hodgkin lymphoma, or osteosarcoma were prospectively assessed for the prevalence of CRFs and compared with an age, sex, and race/ethnicity-matched 2013 National Health and Nutrition Examination Survey (NHANES) population. We estimated future predicted cardiovascular risk based on general population (e.g., Framingham) and Childhood Cancer Survivor Study (CCSS) models. Results: Compared with NHANES (n = 584), survivors [n = 164; 44.5% female, median age 28 years (range, 16–38 years); median 17.4 years (range, 13–22 years) since cancer diagnosis; median doxorubicin dose 300 mg/m2; 30.5% chest radiation] had similar rates of obesity, diabetes, and dyslipidemia, but more prehypertension/hypertension (38.4% vs. 30.1%, P = 0.044). Survivors had fewer metabolic syndrome features compared with NHANES (≥2 features: 26.7% vs. 55.9%; P < 0.001). Survivors were more physically active and smoked tobacco less (both P < 0.0001). Therefore, general population cardiovascular risk scores were lower for survivors versus NHANES. However, with CCSS models, 30.5% of survivors were at moderate risk of ischemic heart disease, and >95% at moderate/high risk for heart failure, with a 9% to 12% predicted incidence of these conditions by age 50 years. Conclusions: Childhood cancer survivors exhibited similar or better cardiometabolic and lifestyle profiles compared with NHANES, but nonetheless are at risk for future clinically significant cardiovascular disease. Impact: Further strategies supporting optimal CRF control are warranted in survivors. See related commentary by Mulrooney, p. 515

Adolescents and young adults (AYAs; age 15-39 years) with cancer are under-represented in cancer clinical trials because of patient, provider, and institutional barriers. Health care technology is increasingly available to and highly used among AYAs and has the potential to improve cancer care delivery. The COVID-19 pandemic forced institutions to rapidly adopt novel approaches for enrollment and monitoring of patients on cancer clinical trials, many of which have the potential for improving AYA trial participation overall. This consensus statement from the Children's Oncology Group AYA Oncology Discipline Committee reviews opportunities to use technology to optimize AYA trial enrollment and study conduct, as well as considerations for widespread implementation of these practices. The use of remote patient eligibility screening, electronic informed consent, virtual tumor boards, remote study visits, and remote patient monitoring are recommended to increase AYA access to trials and decrease the burden of participation. Widespread adoption of these strategies will require new policies focusing on reimbursement for telehealth, license portability, facile communication between electronic health record systems and advanced safeguards to maintain patient privacy and security. Studies are needed to determine optimal approaches to further incorporate technology at every stage of the clinical trial process, from enrollment through study completion.

PURPOSE: Fertility preservation (FP) services are part of comprehensive care for those newly diagnosed with cancer. The capacity to offer these services to children and adolescents with cancer is unknown. METHODS: A cross-sectional survey was sent to 220 Children's Oncology Group member institutions regarding institutional characteristics, structure and organization of FP services, and barriers to FP. Standard descriptive statistics were computed for all variables. The association between site-specific factors and selected outcomes was examined using multivariable logistic regression. RESULTS: One hundred forty-four programs (65.5%) returned surveys. Fifty-three (36.8%) reported a designated FP individual or team. Sperm banking was offered at 135 (97.8%) institutions, and testicular tissue cryopreservation at 37 (27.0%). Oocyte and embryo cryopreservation were offered at 91 (67.9%) and 62 (46.6%) institutions, respectively; ovarian tissue cryopreservation was offered at 64 (47.8%) institutions. The presence of dedicated FP personnel was independently associated with the ability to offer oocyte or embryo cryopreservation (odds ratio [OR], 4.7; 95% CI, 1.7 to 13.5), ovarian tissue cryopreservation (OR, 2.7; 95% CI, 1.2 to 6.0), and testicular tissue cryopreservation (OR, 3.3; 95% CI, 1.4 to 97.8). Only 26 (18.1%) participating institutions offered all current nonexperimental FP interventions. Barriers included cost (70.9%), inadequate knowledge or training (60.7%), difficulty characterizing fertility risk (50.4%), inadequate staffing (45.5%), and logistics with reproductive specialties (38%-39%). CONCLUSION: This study provides the most comprehensive view of the current landscape of FP infrastructure for children and adolescents with cancer and demonstrates that existing infrastructure is inadequate to offer comprehensive services to patients. We discuss modifiable factors to improve patient access to FP.

Background: Although survival has improved dramatically for most adolescents and young adults (AYA; 15–39 years old) with cancer, it remains poor for those presenting with metastatic disease. To better characterize this subset, we conducted a landscape survival comparison with older adults (40–79 years). Methods: Using Surveillance, Epidemiology, and End Results Program data from 2000 to 2016, we examined incident cases of poor-prognosis metastatic cancers (5-year survival < 50%) among AYAs (n = 11,518) and older adults (n = 345,681) and compared cause-specific survival by sociodemographic characteristics (race/ethnicity, sex, and socioeconomic status). Adjusted HRs (aHR) for death from metastatic disease [95% confidence intervals (95% CI)] were compared between AYAs and older adults (Pint). Results: AYAs had significantly better survival than older adults for every cancer site except kidney, where it was equivalent (range of aHRs = 0.91; 95% CI, 0.82–1.02 for kidney cancer to aHR = 0.33; 95% CI, 0.26–0.42 for rhabdomyosarcoma). Compared with their older adult counterparts, greater survival disparities existed for AYAs who were non-Hispanic Black with uterine cancer (aHR = 2.20; 95% CI, 1.25–3.86 versus aHR = 1.40; 95% CI, 1.28–1.54; Pint = 0.049) and kidney cancer (aHR = 1.51; 95% CI, 1.15–1.98 versus aHR = 1.10; 95% CI, 1.03–1.17; Pint = 0.04); non-Hispanic Asian/Pacific Islanders with ovarian cancer (aHR = 1.47; 95% CI, 1.12–1.93 versus aHR = 0.89; 95% CI, 0.84–0.95; Pint Conclusions: AYAs diagnosed with these metastatic cancers have better survival than older adults, but outcomes remain dismal. Impact: Overcoming the impact of metastasis in these cancers is necessary for continuing progress in AYA oncology. Sociodemographic disparities affecting AYAs within kidney, uterine, ovarian, and colorectal cancer could indicate plausible effects of biology, environment, and/or access and should be explored.

Adolescent and young adult (AYA) patients with acute leukemia (AL) have inferior outcomes in comparison to younger patients, and are more likely to develop acute and chronic GVHD than younger children following HLA matched sibling donor stem cell transplant (SCT). We compared the incidence of grade II-IV acute GVHD, chronic GVHD, and survival in AYA (age 13-21 years) to younger children (age 2-12 years) who received an unrelated donor SCT for acute leukemia on Children's Oncology Group trials between 2004-2017. One hundred and eighty-eight children and young adults ages 2-21 years underwent URD SCT. Sixty-three percent were aged 2-12 and 37% were age 13-21. Older age was a risk factor for grade II-IV acute GVHD in multivariate analysis with a hazard ratio (HR) of 1.95 [95% confidence interval (CI) 1.23-3.10], but not for chronic GVHD, HR 1.25 [95% CI 0.57-2.71]. Younger patients relapsed more often (34.5 ± 4.4% vs. 22.8 ± 4.0%, p = 0.032), but their Event-Free Survival (42.6 ± 4.7% vs. 51.8 ± 6.1%, p = 0.18) and Overall Survival at 5 years (48.5 ± 4.9% vs. 51.5 ± 6.4%, p = 0.56) were not different than AYA patients. AYA patients who receive an URD SCT for acute leukemia are significantly more likely to develop grade II-IV acute GVHD, though survival is similar.

- Abstract
Childhood cancer survivors are at high risk of developing congestive heart failure (CHF) compared with the general population, and there is a dose-dependent increase in CHF risk by anthracycline dose. The mechanism by which this occurs has not been fully elucidated. Metabolomics, the comprehensive profile of small-molecule metabolites, has the potential to provide insight into the pathogenesis of disease states and discover diagnostic markers for therapeutic targets. We performed echocardiographic testing and blood plasma metabolomic analyses (8 pathways; 354 metabolites) in 150 asymptomatic childhood cancer survivors previously treated with anthracyclines. Median time from cancer diagnosis to study participation was 12.4 years (2.6–37.9 years); 64% were treated for a hematologic malignancy; median anthracycline dose was 350 mg/m2 (25–642 mg/m2). Thirty-five (23%) participants had cardiac dysfunction—defined as left ventricular end-systolic wall stress >2SD by echocardiogram. Plasma levels of 15 compounds in three metabolic pathways (carbohydrate, amino acid, and lipid metabolism) were significantly different between individuals with cardiac dysfunction and those with normal systolic function. After adjusting for multiple comparisons, individuals with cardiac dysfunction had significantly lower plasma carnitine levels [relative ratio (RR), 0.89; P < 0.01] in relation to those with normal systolic function. These findings may facilitate the development of primary prevention (treatment of carnitine deficiency before/during anthracycline administration) and secondary prevention strategies (screening and treatment in long-term survivors) in patients at highest risk for CHF.

Background The objective of this study was to examine long-term outcomes among children newly diagnosed with cancer who were treated in dexrazoxane-containing clinical trials. Methods P9404 (acute lymphoblastic leukemia/lymphoma [ALL]), P9425 and P9426 (Hodgkin lymphoma), P9754 (osteosarcoma), and Dana-Farber Cancer Institute 95-01 (ALL) enrolled 1308 patients between 1996 and 2001: 1066 were randomized (1:1) to doxorubicin with or without dexrazoxane, and 242 (from P9754) were nonrandomly assigned to receive dexrazoxane. Trial data were linked with the National Death Index, the Organ Procurement and Transplantation Network, the Pediatric Health Information System (PHIS), and Medicaid. Osteosarcoma survivors from the Childhood Cancer Survivor Study (CCSS; n = 495; no dexrazoxane) served as comparators in subanalyses. Follow-up events were assessed with cumulative incidence, Cox regression, and Fine-Gray methods. Results In randomized trials (cumulative prescribed doxorubicin dose, 100-360 mg/m2 ; median follow-up, 18.6 years), dexrazoxane was not associated with relapse (hazard ratio [HR], 0.84; 95% confidence interval [CI], 0.63-1.13), second cancers (HR, 1.19; 95% CI, 0.62-2.30), all-cause mortality (HR, 1.07; 95% CI, 0.78-1.47), or cardiovascular mortality (HR, 1.45; 95% CI, 0.41-5.16). Among P9754 patients (all exposed to dexrazoxane; cumulative doxorubicin, 450-600 mg/m2 ; median follow-up, 16.6-18.4 years), no cardiovascular deaths or heart transplantation occurred. The 20-year heart transplantation rate among CCSS osteosarcoma survivors (mean doxorubicin, 377 ± 145 mg/m2 ) was 1.6% (vs 0% in P9754; P = .13). Among randomized patients, serious cardiovascular outcomes (cardiomyopathy, ischemic heart disease, and stroke) ascertained by PHIS/Medicaid occurred less commonly with dexrazoxane (5.6%) than without it (17.6%; P = .02), although cardiomyopathy rates alone did not differ (4.4% vs 8.1%; P = .35). Conclusions Dexrazoxane did not appear to adversely affect long-term mortality, event-free survival, or second cancer risk.

- Abstract
Purpose Pediatric healthcare systems must support childhood cancer survivors to optimize their transition to adult care. This study aimed to assess the state of healthcare transition services provided by Children's Oncology Group (COG) institutions. Methods A 190-question online survey was distributed to 209 COG institutions to assess survivor services, including transition practices, barriers, and implementation of services aligned with the Six Core Elements of Health Care Transition 2.0 from the US Center for Health Care Transition Improvement. Results Representatives from 137 COG sites reported on institutional transition practices. Two-thirds (66.4%) of sites discharge survivors to another institution for cancer-related follow-up care in adulthood. Transfer to primary care (33.6%) was a commonly reported model of care for young adult-aged survivors. Sites transfer at ≤ 18 years (8.0%), ≤ 21 years (13.1%), ≤ 25 years (7.3%), ≥ 26 years (12.4%), or when survivors are "ready" (25.5%). Few institutions reported offering services aligned with the structured transition process from the Six Core Elements (Median = 1, Mean = 1.56, SD = 1.54, range: 0–5). The most prevalent barriers to transitioning survivors to adult care were perceived lack of late-effects knowledge among clinicians (39.6%) and perceived lack of survivor desire to transfer care (31.9%). Conclusions Most COG institutions transfer adult-aged survivors of childhood cancer elsewhere for survivor care, yet few programs report delivering recognized standards for quality healthcare transition programming to support survivors.

OBJECTIVE: To (1) characterize change in type of insurance coverage among childhood cancer survivors from diagnosis to survivorship and (2) examine whether insurance change is associated with cancer‐related follow‐up care utilization. DATA SOURCES: Participants in this study were derived from the Project Forward study, a population‐based, observational study of childhood cancer survivors in Los Angeles County that used California Cancer Registry data to identify participants. STUDY DESIGN: Multivariable logistic regression models incorporating survey nonresponse weights estimated the change in the marginal predicted probabilities of insurance change and survivorship care, adjusting for demographic, socioeconomic, and clinical covariates and clustering by treating hospital. DATA COLLECTION/EXTRACTION METHODS: Study participants were diagnosed with cancer who were younger than age 20 years while living in Los Angeles County from 1996 to 2010 and were older than the age 18 years at the time of survey participation, from 2015 to 2017 (N = 1106). PRINCIPAL FINDINGS: Most participants were 18–26 years of age, male, diagnosed before 2004, Hispanic/Latino race/ethnicity, single, without children, highly educated, not employed full time, and lived with their parents at survey. Almost half (N = 529) of participants experienced insurance change from diagnosis to survivorship. Insurance change was associated with insurance coverage at diagnosis, as those who were uninsured were most likely to experience change and gain coverage during survivorship (by 51 percentage points [ppt], standard error [SE] of 0.05). Survivors who experienced any change had decreased probability of reporting a recent cancer‐related follow‐up care visit, a disparity that was magnified for those who lost insurance coverage (−5 ppt, SE 0.02 for those who gained coverage; −15 ppt, SE 0.04 for those who lost coverage). CONCLUSIONS: Insurance coverage change was associated with lower cancer‐related follow‐up care utilization. Indeed, survivors who experienced any insurance coverage change had decreased probability of having a cancer‐related follow‐up care visit, and this was magnified for those who lost their insurance coverage.

Background: Younger adolescents and young adults (AYA) may receive care from either adult or pediatric oncologists. We explored patterns of care in this population and whether survival is associated with provider type. Methods: Utilizing the California Cancer Registry, we examined a cohort of 9,993 AYAs diagnosed with cancer aged 15 to 24 years from 1999 to 2008. Provider type (adult/pediatric) was determined by individual physician identifiers. For provider type, multivariable logistic regression models were adjusted for age, sex, race/ethnicity, socioeconomic status, diagnosis, and stage. For observed survival, Cox proportional hazard models were additionally adjusted for provider type. ORs and HR with 95% confidence intervals (95% CI) were determined. Results: Most patients saw adult providers (87.3% overall; 72.7% aged 15–19 years). Patients with acute leukemia, sarcoma, and central nervous system (CNS) malignancies more often saw pediatric providers [OR (95% CI) adult versus pediatric 0.48 (0.39–0.59), 0.74 (0.60–0.92), 0.76 (0.60–0.96), respectively]; those with germ cell tumors and other cancers, including carcinomas, more often saw adult providers [2.26 (1.72–2.98), 1.79 (1.41–2.27), respectively]. In aggregate and for most cancers individually, there was no survival difference by provider type [overall HR (95% CI) 1.00 (0.86–1.18)]. Higher survival was associated with pediatric providers for CNS malignancies [1.63 (1.12–2.37)] and rhabdomyosarcoma [2.22 (1.03–4.76)], and with adult providers for non-Hodgkin lymphoma [0.61 (0.39–0.96)]. Conclusions: Most AYAs 15 to 24 years old are treated by medical oncologists. In general, survival was not associated with provider type. Impact: Current patterns of care for this population support increased collaboration between medical and pediatric oncology, including joint clinical trials.

Background Survivor‐focused care for adolescent and young adult (AYA) childhood cancer survivors (CCS) often involves their parents. Recognizing the importance of parents in the ongoing care of CCS, our study sought to identify key aspects of a successful transition for CCS from pediatric‐ to adult‐centered care from the parent perspective. Methods We conducted qualitative interviews with 26 parents of CCS who were receiving care in the long‐term follow‐up (LTFU) clinic at a single institution. We used a semi‐structured interview protocol with the parents and conducted a thematic content analysis. Results Using a constant comparison approach, data revealed three primary themes regarding parents’ perspectives toward ensuring a seamless transition from pediatric‐ to adult‐centered follow‐up care: (1) the transition needs to include seamless communication between all involved parties, (2) survivors need to demonstrate sufficient health care self‐efficacy in order to achieve a successful transition, and (3) the survivor‐focused care should include support for survivors’ overall well‐being, including financial and health insurance literacy. Conclusions For parents of AYA CCS, the optimal pediatric to adult care transition model should include mechanisms that facilitate communication between parents, CCS, and survivor‐focused providers while also supporting self‐efficacy and financial literacy as it relates to health insurance., Survivor‐focused care for adolescent and young adult (AYA) childhood cancer survivors (CCS) often involves their parents. To parents, adolescent and young adult (AYA) childhood cancer survivors (CCS), the optimal pediatric to adult care transition model should include mechanisms that facilitate communication between parents, CCS, and survivor‐focused providers while also supporting self‐efficacy and financial literacy as it relates to health insurance.

Leukemia and lymphoma (LL) are the most common cancer diagnoses of childhood with high survival rates, but not without impact on the child's functioning and quality of life. This study aimed to use patient-reported data to describe the symptomatic adverse event (AE) experiences among children with LL diagnoses.Two hundred and fifty seven children and adolescents aged 7-18 years with a first LL diagnosis completed the Pediatric Patient-Reported version of the Common Terminology Criteria for Adverse Events (Ped-PRO-CTCAE) and Patient-Reported Outcome Measurement Information System (PROMIS) Pediatric measures before starting a treatment course (T1) and after the treatment (T2).Fatigue was the most severe AE (68.1% at T1; 67% at T2) and caused the most interference over time. Gastrointestinal AEs were also quite common (e.g., nausea 46.3% at T1 and 48.9% at T2; abdominal pain 42.4% at T1; 46.5% at T2). In general, symptoms were present both at T1 and T2 and did not change significantly in severity or interference. The prevalence of AEs varied by LL disease group (e.g., nausea was most common in acute lymphoblastic leukemia (ALL), fatigue was most severe in ALL and Hodgkin Lymphoma (HL), acute myeloid leukemia had the fewest AEs).Despite current supportive care regimens, many children with LL continue to report fatigue, pain, insomnia, and gastrointestinal symptoms as the most frequent or severe symptoms during therapy.

ObjectivePalliative care (PC) is patient and family-centered supportive care intended to improve symptom management, reduce caregiver burden, coordinate care, and improve quality of life for patients diagnosed with serious illness. Optimally, PC is begun close to initial diagnosis and delivered in synchrony with disease-specific treatment until symptom relief or patient death. The purpose of this study was to examine cancer survivors’ knowledge and perceptions of PC using a nationally representative sample of US adults from the Health Information National Trends Survey (HINTS).MethodA total of 593 HINTS respondents reported a personal history of cancer and were included in the sample (55.56% female; mean age of 65.88 years, SD = 18.21; mean time from diagnosis 13.83 years, SD = 18.21). Weighted logistic regression models were conducted to identify correlates of PC knowledge.ResultsOf the 593 cancer survivors in the sample, 66% (N = 378) reported that they had never heard of PC, 18% (N = 112) reported knowing a little bit about PC, and 17% (N = 95) reported knowing what PC is and could explain it to someone else. In multivariable analysis, survivors of color (Hispanic/Latino, Black, Asian, American Indian, and Pacific Islander), males, and those less educated were significantly less likely to report knowledge of PC. Among survivors who did report knowledge of PC, a lack of distinction between differing modes of supportive care exists.Significance of resultsThese findings suggest a need to increase PC knowledge among cancer survivors with the ultimate goal of addressing disparities in PC acceptance and utilization.

Being overweight or obese (OW/OB) during B-cell acute lymphoblastic leukemia (B-ALL) induction is associated with chemoresistance as quantified by minimal residual disease (MRD). We hypothesized that caloric and nutrient restriction from diet/exercise could lessen gains in fat mass (FM) and reduce postinduction MRD. The Improving Diet and Exercise in ALL (IDEAL) trial enrolled patients 10 to 21 years old, newly diagnosed with B-ALL (n = 40), in comparison with a recent historical control (n = 80). Designed to achieve caloric deficits ≥20% during induction, reduce fat intake/glycemic load, and increase activity, IDEAL’s end points were FM gain (primary), MRD ≥0.01%, and adherence/feasibility. Integrated biology explored biomarkers of OW/OB physiology. IDEAL intervention did not significantly reduce median FM change from baseline overall (+5.1% [interquartile range [IQR], 15.8] vs +10.7% [IQR, 16.0]; P = .13), but stratified analysis showed benefit in those OW/OB (+1.5% [IQR, 6.6] vs +9.7% [IQR, 11.1]; P = .02). After accounting for prognostic factors, IDEAL intervention significantly reduced MRD risk (odds ratio, 0.30; 95% confidence interval, 0.09-0.92; P = .02). The trial exceeded its adherence (≥75% of overall diet) and feasibility (≥80% completed visits) thresholds. Integrated biology found the IDEAL intervention increased circulating adiponectin and reduced insulin resistance. The IDEAL intervention was feasible, decreased fat gain in those OW/OB, and reduced MRD. This is the first study in any hematologic malignancy to demonstrate potential benefit from caloric restriction via diet/exercise to augment chemotherapy efficacy and improve disease response. A prospective, randomized trial is warranted for validation. These trials were registered at www.clinicaltrials.gov as #NCT02708108 (IDEAL trial) and #NCT01317940 (historical control).
