Understanding social network support, composition, and structure among cancer caregivers. Psychooncology 2023; 32:408-417.

Abstract
OBJECTIVE We examined the social network support, composition, and structure of pediatric cancer caregivers. METHODS We used a self-report survey to collect egocentric social network data from 107 caregivers of pediatric cancer patients and calculated descriptive statistics to examine cancer-related support network composition, function, and structure. We then ran logistic regressions to examine the relationships between network characteristics and overall satisfaction with social support. RESULTS Family members were the most common source of emotional support and logistical support, and health care providers were the most common source of informational support. Participants perceived the "most helpful" forms of support as being: (1) emotional support from family and health care providers; (2) informational support from health care providers and other cancer caregivers; and (3) logistical support from family. Overall, caregivers wished that 9.8% of their network ties had provided more support, with family members being the most common alter type to disappoint caregivers and offer less support than needed/expected. Caregivers who reported higher network disappointment (having network members who offered less support than needed/expected) were significantly less satisfied with emotional support than those with lower network disappointment (Odds Ratio = 0.18, p = 0.02), and caregivers with higher network disappointment were significantly less satisfied with logistical support compared to those with lower network disappointment (Odds Ratio = 0.14, p = 0.01). CONCLUSION Our results show differences in the nature of social support provided by different types of network members. These findings have implications for tailoring social network interventions to improve caregiver and family outcomes.

Importance of Central Imaging Review in a Pediatric Hodgkin Lymphoma Trial Using PET Response-Adapted Radiotherapy. Int J Radiat Oncol Biol Phys 2023:S0360-3016(23)00164-5. [PMID: 36868525 PMCID: PMC10363760 DOI: 10.1016/j.ijrobp.2023.02.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2022] [Revised: 02/03/2023] [Accepted: 02/07/2023] [Indexed: 03/05/2023]
Abstract
PURPOSE We investigated the impact of central review of the interim fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) scan response (iPET) assessment on treatment allocation on the risk-based, response-adapted, Children's Oncology Group study AHOD1331 (ClinicalTrials.gov: NCT02166463) for pediatric patients with high-risk Hodgkin lymphoma. METHODS AND MATERIALS Per protocol, after 2 cycles of systemic therapy, patients underwent iPET, with visual response assessment by 5-point Deauville score (DS) at their treating institution and a real-time central review, with the latter considered the reference standard. An area of disease with a DS of 1 to 3 was considered a rapid-responding lesion (RRL), whereas a DS of 4 to 5 was considered a slow-responding lesion (SRL). Patients with 1 or more SRLs were considered iPET positive, whereas patients with only RRLs were considered iPET negative. We conducted a predefined exploratory evaluation of concordance in iPET response assessment between institutional and central reviews of 573 patients. The concordance rate was evaluated by using the Cohen kappa statistic (κ; a κ >0.80 was considered very good agreement; >0.60-0.80, good agreement). RESULTS The concordance rate (514/573 [89.7%]) had a κ of 0.685 (95% CI, 0.610-0.759), consistent with "good" agreement. In terms of the direction of discordance, among the 126 patients who were considered iPET positive by institutional review, 38 (30.2%) were categorized as iPET negative by central review, preventing overtreatment with radiotherapy. Conversely, among the 447 patients who were considered iPET negative by institutional review, 21 patients (4.7%) were categorized as iPET positive by the central review and would have been undertreated without radiotherapy. CONCLUSIONS Central review is integral to PET response-adapted clinical trials for children with Hodgkin lymphoma. Continued support of central imaging review and education on DS is needed.

Feasibility of serial neurocognitive assessment using Cogstate during and after therapy for childhood leukemia. Support Care Cancer 2023; 31:109.

Abstract
PURPOSE Neurocognitive impairment is frequently observed among survivors of childhood acute lymphoblastic leukemia (ALL) within the domains of attention, working memory, processing speed, executive functioning, and learning and memory. However, few studies have characterized the trajectory of treatment-induced changes in neurocognitive function beginning in the first months of treatment, to test whether early changes predict impairment among survivors. If correct, we hypothesize that those children who are most susceptible to early impairment would be ideal subjects for clinical trials testing interventions designed to protect against treatment-related neurocognitive decline. METHODS In this pilot study, we prospectively assessed neurocognitive functioning (attention, working memory, executive function, visual learning, and processing speed), using the Cogstate computerized battery at six time points during the 2 years of chemotherapy treatment and 1-year post-treatment (Dana-Farber Cancer Institute ALL Consortium protocol 11-001; NCT01574274). RESULTS Forty-three patients with ALL consented to serial neurocognitive testing. Of the 31 participants who remained on study through the final time point, 1 year after completion of chemotherapy, 28 (90%) completed at least five of six planned Cogstate testing time points. Performance and completion checks indicated a high tolerability (≥ 88%) for all subtests. One year after completion of treatment, 10 of 29 patients (34%) exhibited neurocognitive function more than 2 standard deviations below age-matched norms on one or more Cogstate subtests. CONCLUSIONS Serial collection of neurocognitive data (within a month of diagnosis with ALL, during therapy, and 1-year post-treatment) is feasible and can be informative for evaluating treatment-related neurocognitive impairment.

Abstract
Background: Oral chemotherapy nonadherence is a challenge in clinical oncology. During therapy for acute lymphoblastic leukemia (ALL), poor adherence to 6-mercaptopurine (6MP) increases relapse risk. Clinically significant nonadherence is reported in 30% of children treated for ALL on Children's Oncology Group (COG) trials. Whether nonadherence rates vary across regimens with different treatment schedules and modes of administration is unknown. Methods: We conducted an exploratory, cross-sectional survey study on parents of children (1-18 years) receiving continuation therapy on, or as per Dana-Farber Cancer Institute (DFCI) ALL Consortium Protocol 11-001. Treatment required weekly visits to the clinic and 14 days of oral 6MP every 3 weeks. Survey assessed self-reported sociodemographics, medication-taking, chemotherapy comprehension, and 6MP adherence; adherence survey items were developed from published surveys. Patients were grouped as nonadherent if they endorsed missing one 6MP dose during the last cycle, or more than one dose during prior cycles, for nonmedical reasons. Results: Sixty-two families completed the surveys, all of whom had evaluable adherence data. In total, 25% of patients met the study definition of nonadherence. Twenty-three percent reported that it was "not easy" to follow administration guidelines around the dairy intake and 57% requested more teaching and educational resources. Conclusion: Self-reported nonadherence to oral 6MP in the DFCI ALL Consortium is high, with rates similar to those observed in the COG. This suggests that the additional contact during weekly infusions on the DFCI is insufficient to address barriers affecting oral chemotherapy adherence.

Abstract
BACKGROUND In adults with advanced-stage Hodgkin's lymphoma, the CD30-directed antibody-drug conjugate brentuximab vedotin combined with multiagent chemotherapy has been shown to have greater efficacy, but also more toxic effects, than chemotherapy alone. The efficacy of this targeted therapy approach in children and adolescents with Hodgkin's lymphoma is unclear. METHODS We conducted an open-label, multicenter, randomized, phase 3 trial involving patients 2 to 21 years of age with previously untreated Hodgkin's lymphoma of stage IIB with bulk tumor or stage IIIB, IVA, or IVB. Patients were assigned to receive five 21-day cycles of brentuximab vedotin with doxorubicin, vincristine, etoposide, prednisone, and cyclophosphamide (brentuximab vedotin group) or the standard pediatric regimen of doxorubicin, bleomycin, vincristine, etoposide, prednisone, and cyclophosphamide (standard-care group). Slow-responding lesions, defined by a score of 4 or 5 (on a 5-point scale, with scores of 1 to 3 indicating rapid-responding lesions), were identified on centrally reviewed positron-emission tomography-computed tomography after two cycles. Involved-site radiation therapy was administered after the fifth cycle of therapy to slow-responding lesions and to large mediastinal adenopathy that was present at diagnosis. The primary end point was event-free survival, defined as the time until disease progression occurred, relapse occurred, a second malignant neoplasm developed, or the patient died. Safety and overall survival were assessed. RESULTS Of 600 patients who were enrolled across 153 institutions, 587 were eligible. At a median follow-up of 42.1 months (range, 0.1 to 80.9), the 3-year event-free survival was 92.1% (95% confidence interval [CI], 88.4 to 94.7) in the brentuximab vedotin group, as compared with 82.5% (95% CI, 77.4 to 86.5) in the standard-care group (hazard ratio for event or death, 0.41; 95% CI, 0.25 to 0.67; P<0.001). The percentage of patients who received involved-site radiation therapy did not differ substantially between the brentuximab vedotin group and the standard-care group (53.4% and 56.8%, respectively). Toxic effects were similar in the two groups. Overall survival at 3 years was 99.3% (95% CI, 97.3 to 99.8) in the brentuximab vedotin group and 98.5% (95% CI, 96.0 to 99.4) in the standard-care group. CONCLUSIONS The addition of brentuximab vedotin to standard chemotherapy resulted in superior efficacy, with a 59% lower risk of an event or death, and no increase in the incidence of toxic effects at 3 years.

Abstract
Social determinants of health (SDoH) are associated with stark disparities in cancer outcomes, but systematic SDoH data collection is virtually absent from oncology clinical trials. Trial-based SDoH data are essential to ensure representation of marginalized populations, contextualize outcome disparities, and identify health-equity intervention opportunities. We report the feasibility of a pediatric oncology multicenter therapeutic trial-embedded SDoH investigation. Among 448 trial participants, 392 (87.5%) opted-in to the embedded SDoH study; 375 (95.7%) completed baseline surveys, with high longitudinal response rates (88.9-93.1%) over 24 months. Trial-embedded SDoH data collection is feasible and acceptable and must be consistently included within future oncology trials.

An initial investigation of using smartphone-enabled micro-temporal data collection to increase acceptability, feasibility, and validity of research on cancer caregiving. Pediatr Blood Cancer 2022; 69:e29886. [PMID: 35869890 PMCID: PMC10273258 DOI: 10.1002/pbc.29886] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/28/2022] [Revised: 06/24/2022] [Accepted: 06/26/2022] [Indexed: 11/07/2022]
Abstract
PURPOSE Smartphone-enabled micro-temporal data collection has potential to increase reliability, validity, and feasibility of participant-reported data and is a promising strategy for pediatric oncology supportive care and quality-of-life research. Given the demands of pediatric cancer caregiving, we sought to understand the feasibility and acceptability of smartphone data collection that included short surveys administered daily for 14 days via text message link. METHODS We recruited pediatric cancer caregivers, whose children (ages 0-18 years) were on active treatment, to complete a 14-day daily survey study via smartphone. We implemented our study procedures and examined feasibility through study enrollment rates, reasons for refusal, retention rates, number of reminders and number of completed surveys. We examined acceptability using caregiver ratings of survey length, burden, and ease of completion on a smartphone. RESULTS We recruited (N = 75) caregivers to the study and had an 84% enrollment rate. Reasons for declining participation included passive refusal (n = 13) and too busy (n = 1). The participant retention rate was 100% and compliance with daily survey completion was 99%. Most surveys were completed following two prompts and took participants 5 minutes or less to complete. Caregivers rated the surveys as easy to complete, low burden, and just right in length. CONCLUSION A daily self-report, using a brief (≤5 minutes) survey administered on a smartphone via text message prompt, is a feasible and acceptable method. Future research should extend these findings to understand the generalizability across pediatric cancer caregiving contexts.

Abstract
Children's Oncology Group (COG) trial AHOD0431 reduced systemic therapy and used response-adapted involved-field radiotherapy (IFRT) in early-stage pediatric classic Hodgkin lymphoma. We investigated the impact of positron emission tomographic response after 1 cycle (PET1) and on IFRT outcomes and pattern of relapse. Patients in AHOD0431 underwent PET1 response assessment after AVPC (doxorubicin, vincristine, prednisone, and cyclophosphamide). "Rapid early responders" (RERs) had a negative PET1 (PET1-); "slow early responders" (SERs) had a positive PET1 (PET1+). Patients with a partial response by computed tomographic and functional imaging after 3 chemotherapy cycles received 21-Gy IFRT, whereas complete responders had no IFRT. Progression-free survival (PFS) was evaluated for RERs and SERs treated with or without IFRT. Recurrence sites were initial, new, or both. Relapses involving initial sites were characterized as "within the PET1+ site" or "initially involved but outside the PET1+ site." Median follow-up was 118 months. The 10-year PFS rate among RERs was 96.6% with IFRT and 84.1% without IFRT (P = .10), whereas SERs were 80.9% with IFRT and 64.0% without IFRT (P = .03). Among 90 RERs who did not receive IFRT, all 14 relapses included an initial site. Among 45 SERs receiving no IFRT, 14 of 16 relapses were in the initial site (9 PET1+ site only). Among 58 patients receiving IFRT, 5 of 10 relapses were in the PET1+ site. After 3 cycles of AVPC alone, RERs showed favorable results. Conversely, SERs had unfavorable outcomes with AVPC alone, although they improved with 21-Gy IFRT. RT remains an important component of treatment for SERs. This trial was registered at www.clinicaltrials.gov as #NCT00302003.

Abstract
In pediatric cancer care, medication non-adherence is a significant driver of avoidable suffering and death. There is a lack of interventions designed for families of young children, where patient medication refusal/avoidance is a common barrier to adherence. We developed the CareMeds intervention which focuses on caregiver skills training to help young children take medicine calmly and without use of restraint techniques. The goal of this preliminary study was to assess the acceptability and feasibility of the CareMeds intervention. Caregivers of pediatric cancer patients (ages 2-10) whose children were on a home-based oral medication regimen were recruited to participate. Feasibility was examined through study enrollment and retention rates as well as reasons for refusal and drop out. Acceptability was evaluated through usability of and engagement with intervention components and an acceptability questionnaire. Feasibility: We recruited N = 9 caregivers to participate in this intervention pilot study and had a 75% enrollment rate. Reasons for declining included scheduling concerns (n = 2) and lack of interest (n = 1). The participant retention rate was 100% with 100% adherence to intervention sessions. Acceptability: Parents rated the sessions and resource materials as acceptable and reported frequent use of skills taught in the intervention. The CareMeds intervention is an acceptable and feasible strategy for caregivers of pediatric cancer patients and warrants future research to examine the efficacy of behavioral parenting skills interventions to improve medication adherence in young children.

Abstract
BACKGROUND/OBJECTIVES Although thromboembolism (TE) is a serious complication in patients with acute lymphoblastic leukemia (ALL), thromboprophylaxis is not commonly used due to the inherent bleeding risk in this population. Identifying prothrombotic risk factors will help target thromboprophylaxis to those at highest thrombotic risk. We aimed to define predictors and the impact of TE on ALL outcome in children (1-18 years) treated on the Dana-Farber Cancer Institute ALL 05-001 trial. METHODS Clinical and laboratory data including TE events were prospectively collected. PCR-based allelic discrimination assay identified single-nucleotide polymorphisms (SNP) for prothrombin G20210A (rs1799963) and Factor V G1691A (rs6025). Univariate and multivariable competing risk regression models evaluated the effect of diagnostic clinical (age, sex, body mass index, ALL-immunophenotype, risk group) and laboratory variables (presenting leukocyte count, blood group, SNPs) on the cumulative incidence of TE. Cox regression modeling explored the impact of TE on survival. RESULTS Of 794 patients [median age 4.97 (range, 1.04-17.96) years; males 441], 100 developed TE; 25-month cumulative incidence 13.0% (95% CI, 10.7%-15.5%). Univariate analyses identified older age (≥10 years), presenting leucocyte count, T-ALL, high-risk ALL, and non-O blood group as risk factors. Age and non-O blood group were independent predictors of TE on multivariable regression; the blood group impact being most evident in patients 1-5 years of age (P = 0.011). TE did not impact survival. Induction TE was independently associated with induction failure (OR 6.45; 95% CI, 1.64-25.47; P = 0.008). CONCLUSION We recommend further evaluation of these risk factors and consideration of thromboprophylaxis for patients ≥10 years (especially those ≥15 years) when receiving asparaginase.

Abstract
Patients with therapy-refractory or high-risk relapsed classical Hodgkin lymphoma are typically treated with the high-dose chemotherapy and autologous stem cell transplantation (HDC/ASCT) to consolidate the response to salvage therapy. The combination of brentuximab vedotin with gemcitabine has recently been shown to be an effective and safe salvage regimen. While the majority of patients with complete responses to this regimen ultimately underwent HDC/ASCT consolidation, four subjects, reported herein, achieved durable complete remissions lasting more than 4 years after the study treatment but without ASCT consolidation. Further investigation of treatment strategies incorporating targeted agents may allow omission of HDC/ASCT for select patients.

Abstract
PURPOSE The Children's Oncology Group protocol AHOD0831, for pediatric patients with high-risk classical Hodgkin lymphoma (cHL), used response-adapted radiation fields, rather than larger involved-field radiation therapy (IFRT) that were historically used. This retrospective analysis of patterns of relapse among patients enrolled in the study was conducted to study the potential effect of a reduction in RT exposure. METHODS AND MATERIALS From December 2009 to January 2012, 164 eligible patients under 22 years old with stage IIIB (43%) and stage IVB (57%) enrolled on AHOD0831. All patients received 4 cycles of doxorubicin, bleomycin, vincristine, etoposide, prednisone, and cyclophosphamide (ABVE-PC). Those patients with a slow early response (SER) after the first 2 ABVE-PC courses were nonrandomly assigned to 2 intensification cycles with ifosfamide/vinorelbine before the final 2 ABVE-PC cycles. Response-adapted RT (21 Gy) was prescribed to initial areas of bulky disease and SER sites. Rapid early response (RER) sites without bulk were not targeted. Imaging studies at the time of progression or relapse were reviewed centrally for this retrospective analysis. Relapses were characterized with respect to site (initial, new, or both; and initial bulk or initial nonbulk), initial chemotherapy response, and radiation field (in-field, out-of-field, or both). RESULTS Of the entire cohort, 140 patients were evaluable for the patterns of failure analyses. To investigate the pattern of failure, this analysis focuses on 23 patients who followed protocol treatment and suffered relapses at a median 1.05 years with 7.97-year median follow-up time. These 23 patients (11 RER and 12 SER) experienced a relapse in 105 total sites (median, 4; range, 1-11). Of the 105 relapsed sites, 67 sites (64%) occurred within an initial site of involvement, with 12 of these 67 sites (18%) at an initial site of bulky disease and 63 of these 67 relapses (94%) occurring in sites that were not fluorodeoxyglucose (FDG)-avid after 2 cycles of ABVE-PC (PET2-negative). Of the 105 relapsed sites, 34 sites (32%) occurred in a new site of disease (that would not have been covered by RT); and, overall, only 4 of 140 patients (2.8%) (occurring in 3 RER and 1 SER) experienced isolated out-of-field relapses that would have been covered by historical IFRT. CONCLUSIONS For a cohort of high-risk patients with cHL patients, most failures occurred in nonbulky, initially involved sites, largely due to response-based consolidation RT delivered to patients with bulky disease. In this analysis, we discovered low rates of failures outside of these modern risk-adapted radiation treatment volumes. Also, FDG uptake on PET2 did not identify most relapse sites.

Abstract
Classical Hodgkin lymphoma (cHL) is a common malignancy in children and adolescents. Although cHL is highly curable, treatment with chemotherapy and radiation often come at the cost of long-term toxicity and morbidity. Effective risk-stratification tools are needed to tailor therapy. Here, we used gene expression profiling (GEP) to investigate tumor microenvironment (TME) biology, to determine molecular correlates of treatment failure, and to develop an outcome model prognostic for pediatric cHL. A total of 246 formalin-fixed, paraffin-embedded tissue biopsies from patients enrolled in the Children's Oncology Group trial AHOD0031 were used for GEP and compared with adult cHL data. Eosinophil, B-cell, and mast cell signatures were enriched in children, whereas macrophage and stromal signatures were more prominent in adults. Concordantly, a previously published model for overall survival prediction in adult cHL did not validate in pediatric cHL. Therefore, we developed a 9-cellular component model reflecting TME composition to predict event-free survival (EFS). In an independent validation cohort, we observed a significant difference in weighted 5-year EFS between high-risk and low-risk groups (75.2% vs 90.3%; log-rank P = .0138) independent of interim response, stage, fever, and albumin. We demonstrate unique disease biology in children and adolescents that can be harnessed for risk-stratification at diagnosis. This trial was registered at www.clinicaltrials.gov as #NCT00025259.

Abstract
BACKGROUND Adolescents with Hodgkin lymphoma have worse disease outcomes than children. Whether these differences persist within clinical trials is unknown. We examined survival, by age, in patients receiving response-adapted therapy for Hodgkin lymphoma on Children's Oncology Group (COG) trials. METHODS Patients (aged 1-21 years) diagnosed with classical Hodgkin lymphoma and enrolled between Sept 23, 2002, and Jan 19, 2012, on one of three phase 3 COG trials in the USA and Canada were eligible for inclusion. The three COG trials were defined by risk group according to Ann Arbor stage, B-symptoms, and bulk (AHOD0431 [low risk; NCT00302003], AHOD0031 [intermediate risk; NCT00025259], or AHOD0831 [high risk; NCT01026220]). The outcomes of this study were event-free survival (death, relapse, or subsequent neoplasm) and overall survival. Cox proportional hazards models estimated survival, adjusting for disease and treatment factors both overall and in patients with mixed cellularity or non-mixed cellularity (nodular sclerosing and not-otherwise-specified) disease. FINDINGS Of 2155 patients enrolled on the three trials, 1907 (88·4%; 968 [50·8%] male and 939 [49·2%] female; 1227 [64·3%] non-Hispanic White) were included in this analysis. After a median follow-up of 7·4 years (IQR 4·3-10·2), older patients (aged ≥15 years) had worse unadjusted 5-year event-free survival (80% [95% CI 78-83]) than did younger patients (aged <15 years; 86% [83-88]; HR 1·38 [1·11-1·71]; p=0·0038). Older patients also had worse unadjusted 5-year overall survival than did younger patients (96% [95% CI 95-97] vs 99% [98-99]; HR 2·50 [1·41-4·45]; p=0·0012). In patients with non-mixed cellularity histology, older patients had a significantly increased risk of having an event than did younger patients with the same histology (HR 1·32 [1·03-1·68]; p=0·027). Older patients with mixed cellularity had significantly worse 5-year event-free survival than did younger patients in unadjusted (77% [95% CI 65-86] for older patients vs 94% [88-97] for younger patients; HR 2·93 [1·37-6·29]; p=0·0039) and multivariable models (HR 3·72 [1·56-8·91]; p=0·0032). Overall, older patients were more likely to die than younger patients (HR 3·08 [1·49-6·39]; p=0·0025). INTERPRETATION Adolescents (≥15 years) treated on COG Hodgkin lymphoma trials had worse event-free survival and increased risk of death compared with children (<15 years). Our findings highlight the need for prospective studies to examine tumour and host biology, and to test novel therapies across the age spectrum.

Abstract
BACKGROUND Positron emission tomography (PET)-based measures of baseline total-body tumor burden may improve risk stratification in intermediate-risk Hodgkin lymphoma (HL). MATERIALS AND METHODS Evaluable patients were identified from a cohort treated homogeneously with the same combined modality regimen on the Children's Oncology Group AHOD0031 study. Eligible patients had high-quality baseline PET scans. Metabolic tumor volume (MTV) and total lesion glycolysis (TLG) were each measured based on 15 thresholds for every patient. Univariate and multivariable Cox regression and Kaplan-Meier survival analyses assessed for an association of MTV and TLG with event-free survival (EFS). RESULTS From the AHOD0031 cohort (n = 1712), 86 patients were identified who (i) were treated with four cycles of doxorubicin, bleomycin, vincristine, etoposide, prednisone, cyclophosphamide (ABVE-PC) chemotherapy followed by involved field radiotherapy, and (ii) had a baseline PET scan that was amenable to quantitative analysis. Based on univariate Cox regression analysis, six PET-derived parameters were significantly associated with EFS. For each of these, Kaplan-Meier analyses and the log-rank test were used to compare patients with highest tumor burden (i.e., highest 15%) to the remainder of the cohort. EFS was significantly associated with all six PET parameters (all p < .029). In a multivariable model controlling for important covariates including disease bulk and response to chemotherapy, MTV2BP was significantly associated with EFS (p = .012). CONCLUSION Multiple baseline PET-derived volumetric parameters were associated with EFS. MTV2BP was highly associated with EFS when controlling for disease bulk and response to chemotherapy. Incorporation of baseline MTV into risk-based treatment algorithms may improve outcomes in intermediate-risk HL.

Abstract
PURPOSE Dana-Farber Cancer Institute Acute Lymphoblastic Leukemia (ALL) Consortium Protocol 11-001 assessed efficacy and toxicity of calaspargase pegol (calaspargase), a novel pegylated asparaginase formulation with longer half-life, compared with the standard formulation pegaspargase. METHODS Patients age 1 to ≤ 21 years with newly diagnosed ALL or lymphoblastic lymphoma were randomly assigned to intravenous pegaspargase or calaspargase, 2,500 IU/m2/dose. Patients received one induction dose. Beginning week 7, pegaspargase was administered every 2 week for 15 doses and calaspargase every 3 week for 10 doses (30 weeks). Serum asparaginase activity (SAA) (≥ 0.1 IU/mL considered therapeutic) was assessed 4, 11, 18, and 25 days after the induction dose and before each postinduction dose. RESULTS Between 2012 and 2015, 239 eligible patients enrolled (230 ALL, nine lymphoblastic lymphoma); 120 were assigned to pegaspargase and 119 to calaspargase. After the induction dose, SAA was ≥ 0.1 IU/mL in ≥ 95% of patients on both arms 18 days after dosing. At day 25, more patients had SAA ≥ 0.1 IU/mL with calaspargase (88% v 17%; P ˂ .001). Postinduction, median nadir SAAs were similar (≥ 1.0 IU/mL) for both arms. Of 230 evaluable patients, 99% of pegaspargase and 95% of calaspargase patients achieved complete remission (P = .12), with no difference in frequency of high end-induction minimal residual disease among evaluable patients with B acute lymphoblastic leukemia (B-ALL). There were no differences in frequencies of asparaginase allergy, pancreatitis, thrombosis, or hyperbilirubinemia. With 5.3 years median follow-up, 5-year event-free survival for pegaspargase was 84.9% (SE ± 3.4%) and 88.1% (± SE 3.0%) for calaspargase (P = .65). CONCLUSION Every 3-week calaspargase had similar nadir SAA, toxicity, and survival outcomes compared with every 2-week pegaspargase. The high nadir SAA observed for both preparations suggest dosing strategies can be further optimized.

Abstract
BACKGROUND Although physical activity has been consistently associated with reduced breast cancer mortality, evidence is largely based on data collected at one occasion. We examined how pre- and postdiagnosis physical activity was associated with survival outcomes in high-risk breast cancer patients. METHODS Included were 1340 patients enrolled in the Diet, Exercise, Lifestyle and Cancer Prognosis (DELCaP) Study, a prospective study of lifestyle and prognosis ancillary to a SWOG clinical trial (S0221). Activity before diagnosis, during treatment, and at 1- and 2-year intervals after enrollment was collected. Patients were categorized according to the Physical Activity Guidelines for Americans as meeting the minimum guidelines (yes/no) and incrementally as inactive, low active, moderately active (meeting the guidelines), or high active. RESULTS In joint-exposure analyses, patients meeting the guidelines before and 1 year after diagnosis experienced statistically significant reductions in hazards of recurrence (hazard ratio [HR] = 0.59, 95% confidence interval [CI] = 0.42 to 0.82) and mortality (HR = 0.51, 95% CI = 0.34-0.77); associations were stronger at 2-year follow-up for recurrence (HR = 0.45, 95% CI = 0.31 to 0.65) and mortality (HR = 0.32, 95% CI = 0.19 to 0.52). In time-dependent analyses, factoring in activity from all time points, we observed striking associations with mortality for low- (HR = 0.41, 95% CI = 0.24 to 0.68), moderate- (HR = 0.42, 95% CI = 0.23 to 0.76), and high-active patients (HR = 0.31, 95% CI = 0.18 to 0.53). CONCLUSIONS Meeting the minimum guidelines for physical activity both before diagnosis and after treatment appears to be associated with statistically significantly reduced hazards of recurrence and mortality among breast cancer patients. When considering activity from all time points, including during treatment, lower volumes of regular activity were associated with similar overall survival advantages as meeting and exceeding the guidelines.

Abstract
Background Due to a large variety in treatment outcomes reported in therapeutic trials and lacking patient‐relevant outcomes, it is hard to adequately compare and improve current therapies for patients with capillary malformations (CMs). The Core Outcome Set for Capillary Malformations (COSCAM) project aims to develop a core outcome set (COS) for use in future CM trials, in which we will first develop a core outcome (sub)domain set (CDS). Here, we describe the methods for the development of a CDS and present the results of the first development stage. Methods The COSCAM project is carried out according to the recommendations of the Cochrane Skin Core OUtcomes Set INitiative (CS‐COUSIN) and the Core Outcome Measures in Effectiveness Trials (COMET) initiative. During the first stage, we identified all potentially relevant outcome subdomains based on a systematic review, two focus group sessions and input from patient representatives of Dutch patient organizations and the COSCAM‐founding group. In stage two, we will present the subdomains in a three‐round e‐Delphi study and online consensus meeting, in which CM patients, parents/caregivers and CM experts worldwide rate the importance of the proposed subdomains, hereby finalizing the core outcome (sub)domains of the CDS. Results A total of 67 potential outcome subdomains were included; sixteen were previously used in the literature, 20 were proposed by Dutch patients and their parents/caregivers (n = 13) in focus group sessions and 38 were suggested by the experts of the COSCAM‐founding group. Seven were excluded because of overlap. Conclusion The final CDS may serve as a minimum standard in future CM trials, thereby facilitating adequate comparison of treatment outcomes. After this CDS development, we will select appropriate outcome measurement instruments to measure the core outcome subdomains.

Abstract
10025 Background: Poverty is associated with inferior psychosocial function among parents of children with cancer. Severe parental distress during treatment predicts future poor mental health for both parents and children. It is also associated with impaired parental cognitive bandwidth and executive function, which may have implications for treatment adherence. Efforts to identify poverty-exposures amenable to intervention are essential to improving survivorship quality of life for the > 90% of children with acute lymphoblastic leukemia (ALL) who will be long-term survivors. Household material hardship (HMH) is a targetable poverty exposure defined as at least 1 of 3 unmet basic needs including food, housing, or utilities. Dana-Farber Cancer Institute (DFCI) ALL Consortium trial 16-001 is the first pediatric oncology clinical trial to systematically evaluate HMH. We investigated the hypothesis that HMH exposure independently predicts severe parent psychological distress during ALL therapy. Methods: Patients with newly diagnosed ALL ages 1-17 years were enrolled on the DFCI 16-001 embedded HMH cohort study at 8 U.S. and Canadian centers. Secondary interim analyses used baseline (within 32-days of trial enrollment) and 6-mos parent-reported sociodemographic data, the Kessler-6 (K6) Psychological Distress scale, and trial-collected child and disease data. Severe psychological distress was defined as a K6 > = 13. Multivariable cox regression evaluated baseline HMH-exposure and parent distress at baseline and 6-mos adjusting for child’s initial ALL risk group (Very High Risk (VHR) vs other) and marital status (single vs dual parent). Results: Among 258 families with evaluable data, 34% reported baseline HMH. Families were predominantly English-speaking (54%) dual parent households (71%). Children were a median of 5.7 years (IQR 1.0-17.99) at diagnosis and predominantly non-Hispanic white (66%) with expected disease distribution by immunophenotype (84% B-cell). HMH (odds ratio (OR) 2.18, 95% confidence interval (CI) 1.0-4.31, p = 0.025) and VHR initial risk group (OR 2.32; 95% CI 1.06-5.06, p = 0.035) were independently associated with baseline severe psychological distress. Only HMH was independently associated with 6-mos severe psychological distress (OR 4.93, 95% CI 1.80-13.48, p = 0.002). Future analyses will investigate race and ethnicity associations with parental distress pending trial accrual for statistical power. Conclusions: HMH, a modifiable poverty exposure, is significantly associated with severe parent psychological distress at diagnosis that persists 6-months into pediatric ALL therapy. These findings identify a cohort at high risk of inferior mental health outcomes, and affirm the need for HMH-targeted interventions to support children and parents during cancer treatment to reduce poverty-associated outcome disparities in survivorship.

Abstract
BACKGROUND Childhood acute lymphoblastic leukemia (ALL) is the most common pediatric malignancy. The onset of obesity during childhood ALL has been well established and is associated with inferior survival rates and increased treatment-related toxicities. This pilot study sought to determine if a dietary intervention is feasible and minimizes weight gain during the initial phases of treatment for ALL. METHODS Participants were recruited from four institutions, fluent in English or Spanish, between 5 and 21 years old, and enrolled within 3 days of starting induction therapy. Participants were counseled for 6 months to follow a low glycemic diet. Dietary and anthropometric data were collected at diagnosis, end of induction, and end of month 6 (NCT03157323). RESULTS Twenty-three of 28 participants (82.1%) were evaluable and included in the analysis. Dietary changes targeted by the nutrition intervention were successful; sugar intake declined (P = .003), whereas vegetable intake increased (P = .033). The majority of participants were able to adhere to the dietary principles prescribed: ≥70.0% reduced glycemic load and ≥60.0% increased fiber intake and decreased sugar intake. Importantly, we did not observe an increase in body mass index z-score during induction or over the 6-month intervention period. Most families found the nutrition intervention easy to follow (60%) and affordable (95%) despite simultaneous initiation of treatment for ALL. CONCLUSIONS A 6-month nutrition intervention initiated during the initial phase of treatment for childhood ALL is feasible and may prevent weight gain. Our preliminary findings need to be confirmed in a larger clinical trial.

Abstract
Over the past century, classical Hodgkin lymphoma (HL) has been transformed from a uniformly fatal disease to one of the most curable cancers. Given the high cure rate, a major focus of classical HL management is reducing the use of radiation therapy (RT) and chemotherapy agents such as procarbazine and doxorubicin to minimize long-term toxicities. In both North America and Europe, an important philosophy in the management of classical HL is to guide the intensity of treatment according to the risk category of the disease. The main factors used for risk classification are tumor stage, bulk of disease, and the presence of B symptoms. Response to chemotherapy is an important factor guiding the utilization of RT in ongoing Children's Oncology Group (COG) and European Network Pediatric Hodgkin Lymphoma (EuroNet-PHL) trials. Both trial groups have transitioned to reduced RT volumes that target the highest risk sites using highly conformal techniques, along with standard or intensified chemotherapy regimens to improve outcomes in higher risk patients. However, given the potential acute toxicities of intensified chemotherapy, immunoregulatory drugs are being investigated in upcoming trials. The purpose of this review is to summarize current approaches to treating pediatric classical HL according to the COG and EuroNet-PHL.

Abstract
Survivors of Hodgkin lymphoma (HL) have an increased risk of subsequent malignant neoplasms (SMNs). Response-adapted treatment may decrease this risk by reducing exposure to therapy associated with SMN risk. The Children's Oncology Group study AHOD0031 evaluated response-adapted therapy for children and adolescents with intermediate-risk HL. We report the SMNs among 1711 patients enrolled in AHOD0031. Patients were treated with 4 cycles of doxorubicin, bleomycin, vincristine, etoposide, prednisone, and cyclophosphamide with or without involved-field radiation therapy (RT). Patients with a slow early response to initial chemotherapy were randomized to 2 additional cycles of dexamethasone, etoposide, cisplatin and cytarabine or no additional chemotherapy, and all received RT. At a median follow-up of 7.3 years, an analysis of SMNs was performed. The 10-year cumulative incidence of SMN was 1.3% (95% confidence interval [CI], 0.6-2.0). SMNs included 3 patients with acute myeloid leukemia (AML), 11 with solid tumors, and 3 with non-Hodgkin lymphoma. Sixteen of 17 patients with an SMN had received combined modality therapy. The standardized incidence ratio for SMN was 9.5 (95% CI, 4.5-15.2) with an excess absolute risk of 1.2 per 1000 person-years. The cumulative incidence of SMNs was higher among patients who received RT (P = .037). In multivariate analysis, RT, B symptoms, and race were associated with SMN risk. Given the latency from exposure, we have likely captured all cases of secondary leukemia and myelodysplastic syndrome (MDS). Longer follow-up is needed to determine the risk of solid tumors. Avoidance of RT without sacrificing disease control should remain a goal for future therapeutic approaches. This trial was registered at www.clinicaltrials.gov as #NCT00025259.
