RESUMEN

Germline variants of the RUNX1 gene are associated with RUNX1 Familial Platelet Disorder with Associated Myeloid Malignancies (RUNX1-FPDMM), which is characterized by an increased risk of developing myelodysplastic syndrome (MDS) and/or acute myeloid leukemia. Patients with FPDMM have also been described to develop B- or T-cell acute lymphoblastic leukemia. We present a pediatric patient with RUNX1-FPDMM that evolved into concurrent MDS and T-cell acute lymphoblastic leukemia after a decade of monitoring with serial blood counts. We aim to highlight the treatment challenges and clinical decision-making that may be anticipated in this unique disorder, as well as the potentially curative role for allogenic hematopoietic stem cell transplant in the first complete remission.

RESUMEN

PURPOSE: To develop United States (US) standards for survivorship care that informs (1) essential health system policy and process components and (2) evaluation of the quality of survivorship care. METHODS: The National Cancer Institute and the Department of Veterans Affairs led a review to identify indicators of quality cancer survivorship care in the domains of health system policy, process, and evaluation/assessment. A series of three virtual consensus meetings with survivorship care and research experts and advocates was conducted to rate the importance of the indicators and refine the top indicators. The final set of standards was developed, including ten indicators in each domain. RESULTS: Prioritized items were survivor-focused, including processes to both assess and manage physical, psychological, and social issues, and evaluation of patient outcomes and experiences. Specific indicators focused on developing a business model for sustaining survivorship care and collecting relevant business metrics (e.g., healthcare utilization, downstream revenue) to show value of survivorship care to health systems. CONCLUSIONS: The National Standards for Cancer Survivorship Care can be used by health systems to guide development of new survivorship care programs or services or to assess alignment and enhance services in existing survivorship programs. Given the variety of settings providing care to survivors, it is necessary for health systems to adapt these standards based on factors including age-specific needs, cancer types, treatments received, and health system resources. IMPLICATIONS FOR CANCER SURVIVORS: With over 18 million cancer survivors in the United States, many of whom experience varied symptoms and unmet needs, it is essential for health systems to have a comprehensive strategy to provide ongoing care. The US National Standards for Survivorship Care should serve as a blueprint for what survivors and their families can anticipate after a cancer diagnosis to address their needs.

RESUMEN

BACKGROUND: Survivors of adolescent and young adult (AYA) cancer experience significant psychological distress and encounter barriers to accessing mental health care. Few studies have investigated racial/ethnic disparities in psychological health outcomes among AYA survivors, and none have compared outcomes within a racially minoritized population. METHODS: National Health Interview Survey data (2010-2018) were analyzed that identified non-Hispanic Black (hereafter, Black) survivors of AYA cancer and age- and sex-matched Black noncancer controls. Sociodemographic factors, chronic health conditions, modifiable behaviors (smoking and alcohol use), and psychological outcomes were assessed with χ2 tests. Logistic regression models, adjusted for survey weights, were used to evaluate the odds of psychological distress by cancer status after adjusting for covariates. Interactions between variables and cancer status were investigated. RESULTS: The study included 334 Black survivors of AYA cancer and 3340 Black controls. Compared to controls, survivors were more likely to report moderate/severe distress (odds ratio [OR], 1.64; p < .001), use mental health care (OR, 1.53; p = .027), report an inability to afford mental health care (OR, 3.82; p < .001), and use medication for anxiety and/or depression (OR, 2.16; p = .001). Forty-one percent of survivors reported moderate/severe distress, and only 15% used mental health care. Among survivors, ages 18-39 years (vs. 40-64 years) and current smoking (vs. never smoking) were associated with the presence of moderate/severe distress. Among survivors with distress, high poverty status was associated with reduced utilization of mental health care. CONCLUSIONS: A cancer diagnosis for a Black AYA is associated with greater psychological distress within an already vulnerable population.

RESUMEN

Background: Adolescents and young adults (AYAs) commonly receive cancer care in the community setting, but the availability of treatment options, resources, and support services for this population is not well known. The National Cancer Institute Community Oncology Research Program (NCORP) funds a network of practices whose mission is to increase access to cancer care and clinical trials in the community setting. We describe our interdisciplinary methodological approach to identify and characterize NCORP practices where AYAs receive cancer care. Methods: NCORP practices completed a cross-sectional Landscape Assessment to describe resources and practice characteristics. We established an interdisciplinary team of stakeholders to analyze the Landscape Assessment data relating to AYAs. Through an iterative process, we assessed NCORP practice responses to questions assessing AYA cancer care capacity, determined a threshold to define practices treating AYAs, and characterized these practices. Results: We determined that practices provide cancer care to AYAs if the following criteria were met: (1) endorsed having an AYA program (n = 20), (2) AYAs comprised ≥5% of annual cancer cases (n = 55), or (3) the practice treated ≥50 AYA cancer cases annually (n = 70). Of 271 NCORP practices, 100 (37%) met any criteria, whereas 87 (32%) did not; 84 (31%) could not be classified due to missing or unknown data. Conclusion: Using an interdisciplinary process, we define practices that treat AYAs in the community. We posit a uniform approach to examine resources and practice capacity for AYAs receiving cancer care across the United States to guide future AYA-focused cancer care delivery research development.

RESUMEN

PURPOSE: Individuals diagnosed with cancer between 15 and 39 years (adolescent and young adult [AYA]) face unique vulnerability. Detail is lacking about care delivery for these patients, especially those with ALL. We address these knowledge gaps by describing AYA ALL care delivery details at National Cancer Institute Community Oncology Research Program (NCORP) (sub)affiliates by model of care. METHODS: Participating institutions treated at least one AYA with ALL from 2012 to 2016. Study-specific criteria were used to determine the number of unique clinical facilities (CFs) per NCORP and their model of care (adult/internal medicine [IM], pediatric, mixed [both]). Surveys completed by NCORPs for each CF by model of care captured size, resources, services, and communication. RESULTS: Among 84 participating CFs (adult/IM, n=47; pediatric, n=15; mixed, n=24), 34% treated 5-10 AYAs with ALL annually; adult/IM CFs more often treated <5 (adult/IM, 60%; pediatric, 40%; mixed, 29%). Referral decisions were commonly driven by an age/diagnosis combination (58%), with frequent ALL-specific age minimums (87%) or maximums (80%). Medical, navigational, and social work services were similar across models while psychology was available at more pediatric CFs (pediatric, 80%; adult/IM, 40%; mixed, 46%-54%). More pediatric or mixed CFs reported oncologists interacting with pediatric/adult counterparts via tumor boards (pediatric, 93%; adult/IM, 26%; mixed, 96%) or initiating contact (pediatric, 100%; adult/IM, 77%; mixed 96%); more pediatric CFs reported an affiliated counterpart (pediatric, 53%; adult, 19%). Most CFs reported no AYA-specific resources (79%) or meetings (83%-98%). CONCLUSION: System-level aspects of AYA ALL care delivery have not been examined previously. At NCORPs, these characteristics differ by models of care. Additional work is ongoing to investigate the impact of these facility-level factors on guideline-concordant care in this population. Together, these findings can inform a system-level intervention for diverse practice settings.

RESUMEN

PURPOSE: Database linkage between cancer registries and clinical trial consortia has the potential to elucidate referral patterns of children and adolescents with newly diagnosed cancer, including enrollment into cancer clinical trials. This study's primary objective was to assess the feasibility of this linkage approach. METHODS: Patients younger than 20 years diagnosed with incident cancer during 2012-2017 in the Kentucky Cancer Registry (KCR) were linked with patients enrolled in a Children's Oncology Group (COG) study. Matched patients between databases were described by sex, age, race and ethnicity, geographical location when diagnosed, and cancer type. Logistic regression modeling identified factors associated with COG study enrollment. Timeliness of patient identification by KCR was reported through the Centers for Disease Control and Prevention's Early Case Capture (ECC) program. RESULTS: Of 1,357 patients reported to KCR, 47% were determined by matching to be enrolled in a COG study. Patients had greater odds of enrollment if they were age 0-4 years (v 15-19 years), reported from a COG-affiliated institution, and had renal cancer, neuroblastoma, or leukemia. Patients had lower odds of enrollment if Hispanic (v non-Hispanic White) or had epithelial (eg, thyroid, melanoma) cancer. Most (59%) patients were reported to KCR within 10 days of pathologic diagnosis. CONCLUSION: Linkage of clinical trial data with cancer registries is a feasible approach for tracking patient referral and clinical trial enrollment patterns. Adolescents had lower enrollment compared with younger age groups, independent of cancer type. Population-based early case capture could guide interventions designed to increase cancer clinical trial enrollment.

RESUMEN

Purpose: Adolescents and young adults (AYAs, 15-39 years) with cancer experience disparities in care and outcomes compared with older/younger patients. AYAs receive care from medical and pediatric oncologists, however, little is known about the extent of training fellows receive. This needs assessment evaluating current AYA oncology (AYA-O) education in pediatric and medical oncology fellowship programs to identify knowledge gaps for curricular development. Methods: An anonymous, cross-sectional, web-based survey developed by pediatric and medical oncologists was sent to medical (n = 178) and pediatric (n = 119) hematology/oncology program directors (PDs) at 251 sites in the United States. PDs were asked to participate and distribute the survey to their fellows. Survey questions addressed current AYA curriculum, provider comfort, and priorities for future AYA educational content. Results: Participants from 69/251 programs responded (program response rate = 27%), including 51 PDs (32 pediatric, 19 medical oncology) and 58 fellows (33 pediatric, 25 medical oncology). Eighty-five percent of PDs (44/51) reported lacking formal AYA curricula. Of these, 80% (35/44) offer some topic-specific lectures, while 20% (9/44) provide little/no education for any topics. For nearly all topics, at least 45% of combined respondents reported little/no education. Respondents believe AYA topics are important for inclusion in future curricula. The most important topics for inclusion reported were oncofertility (82%), survivorship (78%), and communication (77%). Conclusions: There are large and actionable gaps in AYA-O education during fellowship training. Efforts are underway to develop AYA-O curriculum to provide both medical and pediatric oncology fellows with the knowledge and skills required to provide optimal AYA care.

RESUMEN

PURPOSE: To examine the prevalence of female sexual dysfunction (FSD), male erectile dysfunction (ED), and the prevalence and correlates of sexual health discussions between early-onset CRC survivors and their health care providers. METHODS: An online, cross-sectional survey was administered in partnership with a national CRC advocacy organization. Respondents (n = 234; diagnosed < 50 years, 6-36 months from diagnosis/relapse) were colon (36.8%) and rectal (63.3%) cancer survivors (62.5% male). The Female Sexual Function Index (FSFI-6) was used to measure FSD, and the International Index of Erectile Function (IIEF-5) was used to measure ED. Survivors reported whether a doctor communicated with them about sexual issues during/after treatment. RESULTS: Among females (n = 87), 81.6% had FSD (mean FSFI-6 score = 14.3 [SD±6.1]). Among males (n = 145), 94.5% had ED (mean IIEF-5 score = 13.6 [SD±3.4]). Overall, 59.4% of males and 45.4% of females reported a sexual health discussion. Among the total sample, older age of diagnosis and relapse were significantly associated with reporting a discussion, while female sex was negatively associated with reporting a sexual health discussion. Among males, older age at diagnosis and relapse, and among females, older age of diagnosis, were significantly associated with reporting a sexual health discussion. CONCLUSION: The prevalence of FSD and ED were high (8 in 10 females reporting FSD, almost all males reporting ED), while reported rates of sexual health discussion were suboptimal (half reported discussion). Interventions to increase CRC provider awareness of patients at risk for not being counseled are needed to optimize long-term health outcomes.

RESUMEN

PURPOSE: Survivors of adolescent and young adult (AYA) cancer experience psychological distress and insufficient access to mental health care. Few studies have investigated racial/ethnic disparities in psychological health outcomes in this population. This study compared psychological distress, mental health care use, and inability to afford mental health care between Hispanic/Latino survivors of AYA cancer and Hispanic/Latino controls. METHODS: The National Health Interview Survey data (2010-2018) were analyzed to identify Hispanic/Latino survivors of AYA cancer and Hispanic/Latino age- and sex-matched non-cancer controls. Sociodemographic, chronic health, modifiable factors, and psychological outcomes were compared using chi-square tests. Logistic regression models with survey weights were used to assess the log-odds of psychological distress in relation to covariates, along with the cancer group. Interactions were evaluated between each variable and cancer group. RESULTS: The study included 370 Hispanic/Latino survivors of AYA cancer (mean time since diagnosis = 12.34 years) and 3700 Hispanic/Latino controls. Compared to controls, survivors were more likely to report moderate/severe distress (OR = 2.23, p < 0.001), use of mental health care (OR = 2.11, p < 0.001) and inability to afford mental health care (OR = 3.05, p < 0.001). Forty-one percent of survivors reported moderate/severe distress and only 16% utilized mental health care. Among survivors, having more than two chronic health conditions and public insurance (compared to private insurance) were associated with the presence of moderate/severe distress. Among survivors experiencing moderate/severe distress, lack of insurance was associated with decreased utilization of mental health care. CONCLUSIONS: Having cancer as an AYA may exacerbate disparities in psychological health within the Hispanic/Latino population.

RESUMEN

PURPOSE: Survival for adolescents and young adults (AYAs) with cancer has improved over the past few decades, and targeted approaches are needed to further improve outcomes. Limited reports suggest that AYAs tolerate cancer treatment differently than older and younger patients. Lack of adverse event (AE) data prevents the optimization of treatment regimens for AYAs by maximizing drug delivery and minimizing treatment-related toxicity. The extent to which the frequency and severity of AEs are reported for AYAs in cancer trials is unknown. METHODS: Using a retrospective, observational design we reviewed all phase II/III clinical trials published in 2021 that included cancer-directed therapy and enrolled at least one patient age 15-39 years diagnosed with one of the five common AYA cancers: breast cancer, colorectal cancer, Hodgkin lymphoma, non-Hodgkin lymphoma, or melanoma. The primary outcome was to determine the proportion of phase II/III trials that report AEs for the AYA population. RESULTS: Of 2,540 publications identified, 182 were included in the final analysis. No studies reported AE data for AYAs separate from older adults. Given the lack of reporting of AEs by age, it was not possible to assess differences in AE frequency or severity or whether AEs were associated with differences in dose reductions, treatment delays, or discontinuation for AYAs. CONCLUSION: Reporting of AEs for AYAs with cancer is absent in the public domain. Failure to account for differences in treatment tolerance between AYAs and older adults may lead to undertreatment or overtreatment and delay progress toward further improving outcomes for AYAs.

RESUMEN

In two randomized trials (Children's Oncology Group ACCL0431 and International Childhood Liver Tumour Strategy Group SIOPEL-6), sodium thiosulfate (STS) demonstrated efficacy in preventing cisplatin-induced hearing loss (CIHL). However, the measures used in those trials have been superseded by the consensus International Society of Paediatric Oncology (SIOP) Ototoxicity Scale. To provide benchmark data for STS efficacy when using this contemporary scale, we reanalyzed ACCL0431 hearing outcomes with the SIOP scale and using multiple timepoints. Compared to the control arm, STS significantly reduced CIHL when assessed by the SIOP scale across these different approaches. These results provide critical data to inform treatment discussions and support future potential trial designs comparing otoprotectants.

RESUMEN

Over the past few decades, 5-year cancer survival has steadily improved for all adolescents and young adults (AYA, 15-39 years at diagnosis) combined. While encouraging, this progress simultaneously highlights a compelling need for improving survival in higher risk AYA subsets and for addressing health outcomes and health-related quality of life (HRQoL) among long-term survivors. The Children's Oncology Group (COG), in collaboration with the National Cancer Institute (NCI) and the adult network groups within the NCI National Clinical Trials Network (NCTN), has developed a large and growing portfolio of therapeutic AYA cancer clinical trials to identify optimal treatment approaches for common AYA cancers. Additional initiatives, led by the COG AYA Oncology Discipline Committee for increasing collaboration between the COG and the adult network groups, optimizing AYA clinical trial enrollment, and standardizing the assessment of HRQoL, have been highly successful to date. Further, NCTN-wide collaborations are currently underway focused on improving survival for AYA malignancies with poor prognosis and, through development of supportive care and care delivery trials, reducing the short- and long-term toxicity caused by cancer treatment. Leveraging the research infrastructure within the NCTN and the NCI Community Oncology Research Program, the COG will continue to champion meaningful advancements in health and survival for AYAs with cancer.

RESUMEN

BACKGROUND: Screening guidelines for childhood cancer survivors treated with radiation currently rely on broad anatomic irradiated regions (IR) to determine risk for late effects. However, contemporary radiotherapy techniques use volumetric dosimetry (VD) to define organ-specific exposure, which supports more specific screening recommendations that could be less costly. PATIENTS AND METHODS: This was a cross-sectional study of 132 patients treated with irradiation at Children's Hospital Los Angeles from 2000 to 2016. For 5 key organs (cochlea, breast, heart, lung, and colon), radiation exposure was determined retrospectively using both IR and VD methods. Under each method, Children's Oncology Group Long-Term Follow-Up Guidelines were used to identify organs flagged for screening and recommended screening tests. Projected screening costs incurred under each method were computed through age 65 using insurance claims data. RESULTS: Median age at the 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%). For all 5 organs, use of VD rather than IR resulted in fewer recommended screening tests. This led to average cumulative estimated savings of $3769 (P = .099), with significant savings in patients with CNS tumors (P = .012). Among patients with savings, average savings were $9620 per patient (P = .016) and significantly more likely for females than males (P = .027). CONCLUSION: Use of VD to enhance precision of guideline-based screening for radiation-related late effects permits fewer recommended screening tests and generates cost-savings.

RESUMEN

BACKGROUND: The psychosocial needs and risks of children with cancer and their families are well-documented including increased risk of parental distress, posttraumatic stress, and anxiety. There is a critical need to provide evidence-based psychosocial care to parents and caregivers of children with cancer. Digital health interventions are important to address many barriers to in-person intervention delivery but are not widely used in pediatric psychosocial cancer care. The COVID-19 pandemic has reinforced the need for flexible, acceptable, and accessible psychosocial digital health interventions. The Electronic Surviving Cancer Competently Intervention Program (eSCCIP) is an innovative digital health intervention for parents and caregivers of children with cancer, delivered through a combination of self-guided web-based content and supplemented by 3 telehealth follow-up sessions with a trained telehealth guide. A Spanish language adaptation of eSCCIP, El Programa Electronico de Intervencion para Superar Cancer Competentemente (eSCCIP-SP), has been developed. The self-guided web-based cores of eSCCIP/eSCCIP-SP are a mix of didactic video content, multifamily video discussion groups featuring parents of children with cancer, and hands-on web-based activities. OBJECTIVE: The objective of this study is to test eSCCIP/eSCCIP-SP in a multisite randomized controlled trial, compared to an internet-based education control condition consisting of information specifically focused on concerns relevant to parents and caregivers of children with cancer. METHODS: Using a randomized controlled clinical trial design, 350 eligible parents and caregivers of children with cancer will be randomly assigned to the intervention (eSCCIP/eSCCIP-SP) or an education control condition. Data will be collected at 3 time points: preintervention (prior to randomization), immediately post intervention (after 6 weeks), and at a 3-month follow-up (from baseline). Participants randomized to either condition will receive study material (eSCCIP/eSCCIP-SP intervention or education control website) in English or Spanish, based on the primary language spoken in the home and participant preference. RESULTS: The primary study end point is a reduction in acute distress from baseline to postintervention, with secondary end points focused on reductions in symptoms of posttraumatic stress and anxiety, and improvements in coping self-efficacy and cognitive coping. An additional exploratory aim will be focused on implementation strategies and potential costs and cost-savings of eSCCIP/eSCCIP-SP, laying the groundwork for future trials focused on dissemination and implementation, stepped-care models, and intervention refinement. CONCLUSIONS: This trial will provide necessary data to evaluate the efficacy of eSCCIP/eSCCIP-SP. This intervention has the potential to be an easily scalable and highly impactful psychosocial treatment option for parents and caregivers of children with cancer.

RESUMEN

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.

RESUMEN

Cancer survivors exposed to anthracycline chemotherapy are at risk for developing cardiomyopathy, which may have delayed clinical manifestation. In a retrospective cross-sectional study, we evaluated the utility of cardiopulmonary exercise testing (CPET) for detecting early cardiac disease in 35 pediatric cancer survivors by examining the associations between peak exercise capacity (measured via percent predicted peak VO2) and resting left ventricular (LV) function on echocardiography and cardiac magnetic resonance imaging (cMRI). We additionally assessed the relationships between LV size on resting echocardiography or cMRI and percent predicted peak VO2 since LV growth arrest can occur in anthracycline-exposed patients prior to changes in LV systolic function. We found reduced exercise capacity in this cohort, with low percent predicted peak VO2 (62%, IQR: 53-75%). While most patients in our pediatric cohort had normal LV systolic function, we observed associations between percent predicted peak VO2 and echocardiographic and cMRI measures of LV size. These findings indicate that CPET may be more sensitive in manifesting early anthracycline-induced cardiomyopathy than echocardiography in pediatric cancer survivors. Our study also highlights the importance of assessing LV size in addition to function in pediatric cancer survivors exposed to anthracyclines.

RESUMEN

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.

RESUMEN

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 site 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. Site 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. IMPLICATIONS FOR CANCER SURVIVORS: Development of best practices for survivor transition is needed to help promote increased early detection and treatment of late effects among adult survivors of childhood cancer.
