- Abstract
Purpose: Although the International Neuroblastoma Risk Group Data Commons (INRGdc) has enabled seminal large cohort studies, the research is limited by the lack of real-world, electronic health record (EHR) treatment data. To address this limitation, we evaluated the feasibility of extracting treatment data directly from EHRs using the REDCap Clinical Data Interoperability Services (CDIS) module for future submission to the INRGdc., Methods: Patients enrolled on the Children's Oncology Group neuroblastoma biology study ANBL00B1 (ClinicalTrials.gov identifier: NCT00904241) who received care at the University of Chicago (UChicago) or the Vanderbilt University Medical Center (VUMC) after the go-live dates for the Fast Healthcare Interoperability Resources (FHIR)-compliant EHRs were identified. Antineoplastic drug orders were extracted using the CDIS module. To validate the CDIS output, antineoplastic agents extracted through FHIR were compared with those queried through EHR relational databases (UChicago's Clinical Research Data Warehouse and VUMC's Epic Clarity database) and manual chart review., Results: The analytic cohort consisted of 41 patients at UChicago and 32 VUMC patients. Antineoplastic drug orders were identified in the extracted EHR records of 39 (95.1%) UChicago patients and 26 (81.3%) VUMC patients. Manual chart review confirmed that patients with missing (n = 8) or discontinued (n = 1) orders in the CDIS output did not receive antineoplastic agents during the timeframe of the study. More than 99% of the antineoplastic drug orders in the EHR relational databases were identified in the corresponding CDIS output., Conclusion: Our results demonstrate the feasibility of extracting EHR treatment data with high fidelity using HL7-FHIR via REDCap CDIS for future submission to the INRGdc.

- Abstract
Purpose: Febrile neutropenia (FN) in pediatric patients with cancer can cause severe infections, and prompt antibiotics are warranted. Extrapolated from other populations, a time-to-antibiotic (TTA) metric of <60 minutes after medical center presentation was established, with compliance data factoring into pediatric oncology program national rankings., Methods: All FN episodes occurring at Vanderbilt Children's Hospital (2007-February 2022) and a sample of episodes from Colorado Children's Hospital (2012-2019) were abstracted, capturing TTA and clinical outcomes including major complications (intensive care unit [ICU] admission, vasopressors, intubation, or infection-related mortality). Odds ratios (ORs) were adjusted for age, treatment center, absolute neutrophil count, hypotension presence, stem-cell transplant status, and central line type., Results: A total of 2,349 episodes were identified from Vanderbilt (1,920) and Colorado (429). Only 0.6% (n = 14) episodes required immediate ICU management, with a median TTA of 28 minutes (IQR, 20-37). For the remaining patients, the median TTA was 56 minutes (IQR, 37-90), and 54.3% received antibiotics in <60 minutes. There were no significant associations between TTA (<60 or ≥60 minutes) and major complications (adjusted OR, 0.99 [95% CI, 0.62 to 1.59]; P = .98), and a TTA ≥60 minutes was not associated with any type of complication. Similarly, TTA, when evaluated as a continuous variable, was not associated with a major (OR, 0.99 [95% CI, 0.94 to 1.04]; P = .69) nor any other complication in adjusted analysis., Conclusion: There is no clear evidence that a reduced TTA improves clinical outcomes in pediatric oncology FN and thus it should not be used as a primary quality measure.

- Abstract
Purpose: Cancer survivors develop cancer and treatment-related morbidities at younger than normal ages and are at risk for early mortality, suggestive of an aging phenotype. The Cumulative Illness Rating Scale for Geriatrics (CIRS-G) is specifically designed to describe the accumulation of comorbidities over time with estimates of severity such as total score (TS) which is a sum of possible conditions weighted by severity. These severity scores can then be used to predict future mortality., Methods: CIRS-G scores were calculated in cancer survivors and their siblings from Childhood Cancer Survivor Study cohort members from two time points 19 years apart and members of the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2004. CIRS-G metrics were analyzed using Cox proportional hazards regression to determine subsequent mortality risk., Results: In total, 14,355 survivors with a median age of 24 (IQR, 18-30) years and 4,022 siblings with a median age of 26 (IQR, 19-33) years provided baseline data; 6,138 survivors and 1,801 siblings provided follow-up data. Cancer survivors had higher median baseline TS than siblings at baseline (5.75 v 3.44) and follow-up (7.76 v 4.79), all P < .01. The mean increase in TS from baseline to follow-up was significantly steeper in cancer survivors (2.89 males and 3.18 females) vs. siblings (1.79 males and 1.69 females) and NHANES population (2.0 males and 1.94 females), all P < .01. Every point increase in baseline TS increased hazard for death by 9% (95% CI, 8 to 10) among survivors., Conclusion: Application of a geriatric rating scale to characterize disease supports the hypothesis that morbidity accumulation is accelerated in young adult survivors of childhood cancer when compared with siblings and the general population.

- Abstract
Purpose: Management of febrile pediatric patients with cancer with an absolute neutrophil count of 500/µL or greater is unclear. The Esbenshade Vanderbilt (EsVan) risk prediction models have been shown to predict bloodstream infection (BSI) likelihood in this population, and this study sought to prospectively validate and implement these models in clinical practice., Methods: Data were prospectively collected on febrile pediatric patients with cancer with a central venous catheter from April 2015 to August 2019 at a single site, at which the models (EsVan: 2015 to 2017; EsVan2: October 2017 to 2019) were initially developed and subsequently implemented for clinical management in well-appearing nonseverely neutropenic individuals. It was recommended that patients with low BSI risk (< 10%) be discharged home without antibiotics, those with intermediate BSI risk (10%-39.9%) be administered an antibiotic before discharge, and those with high BSI risk (> 40%) be admitted on broad-spectrum antibiotics. Seven-day outcomes were then collected and EsVan models were prospectively validated and C-statistics estimated., Results: In 937 febrile, nonsevere neutropenia episodes, frequencies of low-, intermediate-, and high-risk episodes were 88.9%, 8.6%, and 2.3% respectively. BSI incidence was 4.2% (39 of 937). Within risk groups, low-risk BSI incidence was 1.9% (16 of 834) with BSI incidence of 13.6% and 54.5% for intermediate- and high-risk episodes, respectively. Empirical intravenous antibiotics were administered in 21.1% of low-risk episodes at presentation and at 7 days postpresentation, 72.3% of episodes never required intravenous antibiotics. There were no deaths or clinical decompensations attributable to antibiotic delay. For BSI detection, EsVan and EsVan2 models applied to the new cohort achieved C-statistics of 0.802 and 0.824, respectively., Conclusion: Prospective, real-time clinical utilization of the EsVan models accurately predicts BSI risk and safely reduces unnecessary antibiotic use in febrile, nonseverely neutropenic pediatric patients with cancer.

- Abstract
Purpose: Accreditation requirements for cancer centers by the American College of Surgeons' Commission on Cancer have included provision of survivorship care plans (SCPs) to patients treated with curative intent soon after completion of therapy. These were traditionally provided in a dedicated survivorship clinic for our pediatric oncology patients later in the survivorship time period. Our goal was to increase timely provision of SCPs to eligible patients in our acute care pediatric oncology clinic and to have this serve as a bridge to longer-term survivorship care., Methods: Our pediatric oncology clinic used quality improvement methodology to implement a process for creation of SCPs. We defined eligible patients on the basis of curative intent. Cancer registry data were queried to find eligible patients, and chart reviews were done weekly. A P chart and run chart were used to monitor our process for creation of plans and overall completion rate, respectively., Results: During the intervention period, we increased the percentage of eligible patients with an SCP from 28% on June 30, 2017, to 53% by December 31, 2017. Since that time, we have continued to increase the percentage of patients with SCPs, reaching 69% by June 30, 2019., Conclusion: By using quality improvement methodology, our pediatric oncology clinic was able to change its clinical practice and implement a sustainable process for provision of SCPs and survivorship planning earlier in the post-treatment course, and meet the Commission on Cancer accreditation standard.

- Abstract
Purpose: Population-based studies of children and adolescents with Hodgkin lymphoma (HL) report a survival disadvantage in nonwhite-non-Hispanic black (NHB) and Hispanic-patients. Whether disparities persist after adjustment for clinical and treatment-related variables is unknown. We examined survival by race/ethnicity in children receiving risk-based, response-adapted, combined-modality therapy for HL in contemporary Children's Oncology Group trials., Patients and Methods: This pooled analysis used individual-level data from 1,605 patients (younger than age 1 to 21 years) enrolled in phase III trials for low-risk (AHOD0431), intermediate-risk (AHOD0031), and high-risk (AHOD0831) HL from 2002 to 2012. Event-free survival (EFS) and overall survival (OS) were compared between non-Hispanic white (NHW) and nonwhite patients. Cox proportional hazards for survival were estimated for both de novo and relapsed HL, adjusting for demographics, disease characteristics, and therapy., Results: At median follow up of 6.9 years, cumulative incidence of relapse was 17%. Unadjusted 5-year EFS and OS were 83% (SE, 1.2%) and 97% (SE, < 1%), respectively. Neither differed by race/ethnicity. In multivariable analyses for OS, nonwhite patients had a 1.88× higher hazard of death (95% CI, 1.1 to 3.3). Five-year postrelapse survival probabilities by race were as follows: NHW, 90%; NHB, 66%; and Hispanic, 80% ( P < .01). Compared with NHW, Hispanic and NHB children had 2.7-fold (95% CI, 1.2 to 6.2) and 3.5-fold (95% CI, 1.5 to 8.2) higher hazard of postrelapse mortality, respectively., Conclusion: In patients who were treated for de novo HL in contemporary Children's Oncology Group trials, EFS did not differ by race/ethnicity; however, adjusted OS was significantly worse in nonwhite patients, a finding driven by increased postrelapse mortality in this population. Additional studies examining treatment and survival disparities after relapse are warranted.

- Abstract
Purpose: Survivors of childhood cancer have an increased risk for subsequent neoplasms (SNs), but the incidence beyond the age of 40 years and associations with therapeutic exposures have not been well described., Patients and Methods: Among 14,364 survivors of childhood cancer diagnosed between 1970 and 1986, 3,171 had an attained age of 40 years or older at the time of last contact. Cumulative incidence of SNs, standardized incidence ratios (SIRs), excess absolute risk of subsequent malignant neoplasms (SMNs), and relative risks (RRs) for SMNs and nonmelanoma skin cancers were calculated., Results: In total, 679 SNs were diagnosed in patients age 40 years or older. These included 196 SMNs, 419 nonmelanoma skin cancers, 21 nonmalignant meningiomas, and 43 other benign neoplasms. At age 55 years, the cumulative incidence of new SNs and SMNs occurring after age 40 years was 34.6% (95% CI, 28.7 to 40.6) and 16.3% (95% CI, 11.7 to 20.9), respectively. Survivors were twice as likely as the general population to receive a diagnosis of SMN after age 40 years (SIR, 2.2; 95% CI, 1.9 to 2.5). Among SMNs, risk was increased for breast cancer (SIR, 5.5; 95% CI, 4.5 to 6.7), renal cancer (SIR, 3.9; 95% CI, 2.0 to 7.5), soft tissue sarcoma (SIR, 2.6; 95% CI, 1.5 to 4.4), and thyroid cancer (SIR, 1.9; 95% CI, 1.0 to 3.5). Female sex (RR, 1.9; 95% CI, 1.3 to 2.6; P < .001) and therapeutic radiation exposure (RR, 2.2; 95% CI, 1.4 to 3.3; P < .001) were associated with an increased for risk for SMN in multivariable analysis., Conclusion: Even after age 40 years, survivors of childhood cancer remain at increased risk for treatment-related SNs. These data suggest the need for life-long monitoring and should inform anticipatory guidance provided to survivors of childhood cancer., (© 2015 by American Society of Clinical Oncology.)

- Abstract
Purpose: The Children's Oncology Group study AHOD0031, a randomized phase III study, was designed to evaluate the role of early chemotherapy response in tailoring subsequent therapy in pediatric intermediate-risk Hodgkin lymphoma. To avoid treatment-associated risks that compromise long-term health and to maintain high cure rates, dose-intensive chemotherapy with limited cumulative doses was used., Patients and Methods: Patients received two cycles of doxorubicin, bleomycin, vincristine, etoposide, cyclophosphamide, and prednisone (ABVE-PC) followed by response evaluation. Rapid early responders (RERs) received two additional ABVE-PC cycles, followed by complete response (CR) evaluation. RERs with CR were randomly assigned to involved-field radiotherapy (IFRT) or no additional therapy; RERs with less than CR were nonrandomly assigned to IFRT. Slow early responders (SERs) were randomly assigned to receive two additional ABVE-PC cycles with or without two cycles of dexamethasone, etoposide, cisplatin, and cytarabine (DECA). All SERs were assigned to receive IFRT., Results: Among 1,712 eligible patients, 4-year event-free survival (EFS) was 85.0%: 86.9% for RERs and 77.4% for SERs (P < .001). Four-year overall survival was 97.8%: 98.5% for RERs and 95.3% for SERs (P < .001). Four-year EFS was 87.9% versus 84.3% (P = .11) for RERs with CR who were randomly assigned to IFRT versus no IFRT, and 86.7% versus 87.3% (P = .87) for RERs with positron emission tomography (PET) -negative results at response assessment. Four-year EFS was 79.3% versus 75.2% (P = .11) for SERs who were randomly assigned to DECA versus no DECA, and 70.7% versus 54.6% (P = .05) for SERs with PET-positive results at response assessment., Conclusion: This trial demonstrated that early response assessment supported therapeutic titration (omitting radiotherapy in RERs with CR; augmenting chemotherapy in SERs with PET-positive disease). Strategies directed toward improved response assessment and risk stratification may enhance tailoring of treatment to patient characteristics and response., (© 2014 by American Society of Clinical Oncology.)

- Abstract
Purpose: Carbonyl reductases (CBRs) catalyze reduction of anthracyclines to cardiotoxic alcohol metabolites. Polymorphisms in CBR1 and CBR3 influence synthesis of these metabolites. We examined whether single nucleotide polymorphisms in CBR1 (CBR1 1096G>A) and/or CBR3 (CBR3 V244M) modified the dose-dependent risk of anthracycline-related cardiomyopathy in childhood cancer survivors., Patients and Methods: One hundred seventy survivors with cardiomyopathy (patient cases) were compared with 317 survivors with no cardiomyopathy (controls; matched on cancer diagnosis, year of diagnosis, length of follow-up, and race/ethnicity) using conditional logistic regression techniques., Results: A dose-dependent association was observed between cumulative anthracycline exposure and cardiomyopathy risk (0 mg/m(2): reference; 1 to 100 mg/m(2): odds ratio [OR], 1.65; 101 to 150 mg/m(2): OR, 3.85; 151 to 200 mg/m(2): OR, 3.69; 201 to 250 mg/m(2): OR, 7.23; 251 to 300 mg/m(2): OR, 23.47; > 300 mg/m(2): OR, 27.59; P(trend) < .001). Among individuals carrying the variant A allele (CBR1:GA/AA and/or CBR3:GA/AA), exposure to low- to moderate-dose anthracyclines (1 to 250 mg/m(2)) did not increase the risk of cardiomyopathy. Among individuals with CBR3 V244M homozygous G genotypes (CBR3:GG), exposure to low- to moderate-dose anthracyclines increased cardiomyopathy risk when compared with individuals with CBR3:GA/AA genotypes unexposed to anthracyclines (OR, 5.48; P = .003), as well as exposed to low- to moderate-dose anthracyclines (OR, 3.30; P = .006). High-dose anthracyclines (> 250 mg/m(2)) were associated with increased cardiomyopathy risk, irrespective of CBR genotype status., Conclusion: This study demonstrates increased anthracycline-related cardiomyopathy risk at doses as low as 101 to 150 mg/m(2). Homozygosis for G allele in CBR3 contributes to increased cardiomyopathy risk associated with low- to moderate-dose anthracyclines, such that there seems to be no safe dose for patients homozygous for the CBR3 V244M G allele. These results suggest a need for targeted intervention for those at increased risk of cardiomyopathy.

- Abstract
Purpose: To evaluate the incidence of and risk factors for basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) in survivors of hematopoietic cell transplantation (HCT)., Patients and Methods: The impact of patient-, disease-, treatment-, and toxicity-related factors on risk of BCC and SCC was determined in a retrospective cohort study of 4,810 patients who received allogeneic HCT and who survived for at least 100 days., Results: Among allogeneic HCT recipients, 237 developed at least one skin or mucosal cancer (BCC, n = 158; SCC, n = 95). Twenty-year cumulative incidences of BCC and SCC were 6.5% and 3.4%, respectively. Total-body irradiation was a significant risk factor for BCC (P = .003), most strongly among patients younger than 18 years old at HCT (P = .02, interaction). Light-skinned patients had an increased risk of BCC (P = .01). Acute graft-versus-host disease (GVHD) increased the risk of SCC (P = .02), whereas chronic GVHD increased the risk of both BCC (P = .01) and SCC (P < .001)., Conclusion: This analysis suggests that immutable factors, such as age and complexion, have a significant impact on BCC and SCC. However, specific treatment (radiotherapy) and transplantation complications (GVHD) may modify that risk. These additional risk factors suggest the contribution of immunologic mechanism DNA and tissue repair in the development of BCC and SCC. We confirm previous reports that exposure to ionizing radiation increases the risk of BCC but not SCC. Survivors of HCT should be monitored for the development of BCC and SCC and use preventive strategies.

- Abstract
Purpose: To determine the risk of subsequent carcinomas other than breast, thyroid, and skin, and to identify factors that influence the risk among survivors of childhood cancer., Patients and Methods: Subsequent malignant neoplasm history was determined in 13,136 participants (surviving > or = 5 years postmalignancy, diagnosed from 1970 to 1986 at age < 21 years) of the Childhood Cancer Survivor Study to calculate standardized incidence ratios (SIRs), using Surveillance, Epidemiology, and End Results data., Results: In 71 individuals, 71 carcinomas were diagnosed at a median age of 27 years and a median elapsed time of 15 years in the genitourinary system (35%), head and neck area (32%), gastrointestinal tract (23%), and other sites (10%). Fifty-nine patients (83%) had received radiotherapy, and 42 (59%) developed a second malignant neoplasm in a previous radiotherapy field. Risk was significantly elevated following all childhood diagnoses except CNS neoplasms, and was highest following neuroblastoma (SIR = 24.2) and soft tissue sarcoma (SIR = 6.2). Survivors of neuroblastoma had a 329-fold increased risk of renal cell carcinomas; survivors of Hodgkin's lymphoma had a 4.5-fold increased risk of gastrointestinal carcinomas. Significantly elevated risk of head and neck carcinoma occurred in survivors of soft tissue sarcoma (SIR = 22.6), neuroblastoma (SIR = 20.9), and leukemia (SIR = 20.9)., Conclusion: Young survivors of childhood cancers are at increased risk of developing subsequent carcinomas typical of later adulthood, underscoring the importance of long-term follow-up and risk-based screening. Follow-up of the cohort is ongoing to determine lifetime risk and delineate individual characteristics that contribute to risk.

- Abstract
The Children's Oncology Group Long-Term Follow-Up Guidelines for Survivors of Childhood, Adolescent, and Young Adult Cancers are risk-based, exposure-related clinical practice guidelines intended to promote earlier detection of and intervention for complications that may potentially arise as a result of treatment for pediatric malignancies. Developed through the collaborative efforts of the Children's Oncology Group Late Effects Committee, Nursing Discipline, and Patient Advocacy Committee, these guidelines represent a statement of consensus from a multidisciplinary panel of experts in the late effects of pediatric cancer treatment. The guidelines are both evidence-based (utilizing established associations between therapeutic exposures and late effects to identify high-risk categories) and grounded in the collective clinical experience of experts (matching the magnitude of risk with the intensity of screening recommendations). They are intended for use beginning 2 or more years following the completion of cancer therapy; however, they are not intended to provide guidance for follow-up of the survivor's primary disease. A complementary set of patient education materials ("Health Links") was developed to enhance follow-up care and broaden the application of the guidelines. The information provided in these guidelines is important for health care providers in the fields of pediatrics, oncology, internal medicine, family practice, and gynecology, as well as subspecialists in many fields. Implementation of these guidelines is intended to increase awareness of potential late effects and to standardize and enhance follow-up care provided to survivors of pediatric cancer throughout the lifespan. The Guidelines, and related Health Links, can be downloaded in their entirety at www.survivorshipguidelines.org.

- Abstract
Purpose: With improvement in survival after childhood cancer, increasing emphasis is being placed on the impact of treatment and its sequelae on the health-related quality of life (HRQL) of survivors. The Minneapolis-Manchester Quality of Life Instrument (MMQL) is a standardized patient self-report instrument designed to assess HRQL in survivors of childhood cancer. The MMQL is being developed for three age groups to address the changing developmental need of different ages: MMQL-Youth (8 to 12 years), MMQL-Adolescent (13 to 20 years), and MMQL-Young Adult (21 to 45 years). This report focuses on the development and testing of the MMQL-Adolescent Form., Patients and Methods: To validate the instrument, the MMQL-Adolescent Form was administered to 397 adolescents (129 healthy individuals, 110 patients with cancer undergoing therapy, and 158 subjects off therapy for cancer). Factor analysis was conducted to refine the instrument. Construct validity was conducted by comparing similar constructs in the MMQL-Adolescent Form and the Child Health Questionnaire (CHQ). Discriminate validity was determined by comparing healthy children with children with cancer either on or off therapy. Stability of the MMQL was tested by readministering the MMQL-Adolescent Form 2 weeks later., Results: Internal consistency reliability was in the acceptable range for this instrument. The MMQL was able to discriminate between the three study populations. There were high correlations between the MMQL scales and similar CHQ domains. Test-retest reliability of the MMQL-Adolescent Form demonstrated that the instrument was extremely stable in all scales tested., Conclusion: Overall, the data provide evidence for the validity and reliability of the MMQL-Adolescent Form as a comprehensive, multidimensional self-report instrument for measuring HRQL among adolescent survivors of childhood cancer.

- Abstract
Purpose: To study the effectiveness of combined systemic chemotherapy and local ophthalmic therapy for retinoblastoma with the goal of avoiding enucleation and external-beam radiation therapy (EBRT)., Patients and Methods: This was a prospective, nonrandomized, single-arm clinical trial. Seventy-five eyes were followed in 47 children. Patients were treated with a six-cycle protocol of vincristine, etoposide, and carboplatin. Most (83%) also received ophthalmic treatment (cryotherapy, laser photocoagulation, thermotherapy, or plaque radiation therapy) during and/or after the chemotherapy., Results: With a median follow-up of 13 months, event-free survival was 74%, with an event defined as enucleation and/or EBRT. Six children required EBRT in seven eyes (9%); five required enucleation of one eye (7%); five required a combination of EBRT and enucleation in six eyes (8%). Reese-Ellsworth groups 1, 2, and 3 eyes had excellent results, with avoidance of EBRT or enucleation in all 39. Treatment of groups 4 and 5 was less successful, with 33% of six eyes and 53% of 30 eyes, respectively, requiring EBRT and/or enucleation. Toxicities from chemotherapy were mild and included cytopenias (89%), fever and neutropenia (28%), infection (9%), and gastrointestinal symptoms, dehydration, and vincristine neurotoxicity (40%). No patients developed a second malignancy, metastatic disease, renal disease, or ototoxicity., Conclusion: In retinoblastoma patients with Reese-Ellsworth eye groups 1, 2, or 3, systemic chemotherapy used with local ophthalmic therapies can eliminate the need for enucleation or EBRT without significant systemic toxicity. More effective therapy is required for Reese-Ellsworth eye groups 4 and 5.
