Randomized Waitlist-Control Trial of a Web-Based Stress-Management and Resiliency Program for Adolescent and Young Adult Cancer Survivors: Protocol for the Bounce Back Study.

BACKGROUND: The emotional health of adolescent and young adult (AYA) cancer survivors is compromised both during and after cancer treatment. Targeted programs designed to support AYAs' ability to cope with stress in the years following treatment completion are lacking. Mind-body programs may ameliorate the negative psychological and emotional effects of stress and assist AYAs with managing the psychosocial challenges of early survivorship. OBJECTIVE: Our randomized waitlist-control trial aims to assess the feasibility, acceptability, and preliminary efficacy of a virtual group program (Bounce Back) to promote stress management and resiliency among posttreatment AYAs. METHODS: Bounce Back is a stress management and resiliency program delivered via videoconference by a trained mental health clinician. Sessions were adapted from an evidence-based mind-body program (Stress Management and Resiliency Training - Relaxation Response Resiliency Program [SMART-3RP]) grounded in relaxation response elicitation, mindfulness, cognitive behavioral therapy, and positive psychology. Seventy-two AYAs (diagnosed with cancer between ages 14 years and 29 years and had completed cancer treatment within the last 5 years) were randomly assigned to the Bounce Back program or waitlist-control group and completed assessments at baseline, 3 months postbaseline, and 6 months postbaseline. The primary aim of the study is to determine the feasibility and acceptability of the Bounce Back program. Descriptive statistics, including means, frequencies, and ranges supplemented by qualitative exit interview feedback will be used to characterize the sample and to summarize feasibility and acceptability. The exploratory aims are to evaluate the preliminary effects of the program on stress coping and psychosocial outcome measures (ie, anxiety, depression) collected across the 3 time points. RESULTS: This study was funded by the National Cancer Institute in July 2017. Study procedures were approved by the Dana-Farber Harvard Cancer Center Institutional Review Board in October 2018 (Protocol 18-428). The randomized trial was conducted from July 2019 to March 2021. Quantitative data collection is complete, and qualitative exit interview data collection is ongoing. Results are expected to be published in peer-reviewed journals and presented at local, national, or international meetings in the coming years. CONCLUSIONS: Few evidence-based programs exist that tackle the key transitional issues faced by AYA cancer survivors. Future analyses will help us determine the feasibility and acceptability of the Bounce Back program and its impact on AYA stress coping and psychological well-being.

A comparison study assessing neuropsychological outcome of patients with post-operative pediatric cerebellar mutism syndrome and matched controls after proton radiation therapy.

PURPOSE: Post-operative pediatric cerebellar mutism syndrome (CMS), characterized by mutism, ataxia/hypotonia, and emotional lability, can result in long-term deficits following resection of posterior fossa (PF) tumors. This longitudinal study compared neuropsychological outcomes of pediatric patients with post-operative CMS to a matched control patient group without CMS. METHODS: Fifty-eight PF tumor patients received post-surgical proton radiation therapy (PRT) and testing at baseline and at ≥ 1-year post-PRT over a 10-year period. Of these, 18 (31%) had post-operative CMS with baseline and follow-up neuropsychological test data. Those participants were matched to 18 controls by tumor location, age, gender, and handedness; no significant group differences were found at baseline for clinical/demographic variables. Total mean age at baseline was 7.26 years (SD = 4.42); mean follow-up interval was 3.26 years (SD = 2.24). Areas assessed: overall intelligence, expressive and receptive vocabulary, visuomotor integration, fine motor speed, inhibition, emotional control, depression, and anxiety. RESULTS: Patients were 52% male; 86% medulloblastoma/14% ependymoma; 86% craniospinal irradiation/14% focal radiation; and 86% chemotherapy. No group differences were found between most mean baseline scores; expressive vocabulary and fine motor speed were significantly lower in the post-operative CMS group (p < 0.05). Mean change scores revealed no significant differences for the sample; scores were within the normal range except fine motor skills were impaired for both groups. CONCLUSIONS: Longitudinal neuropsychological outcomes for post-operative pediatric CMS patients did not differ significantly from matched controls without this condition. Patients were in the normal range in all areas except fine motor speed, which was impaired for both groups independent of CMS diagnosis.

Pediatric postoperative cerebellar cognitive affective syndrome follows outflow pathway lesions.

OBJECTIVE: To evaluate lesion location after pediatric cerebellar tumor resection in relation to the development of severe cognitive and affective disturbances, or cerebellar cognitive affective syndrome (CCAS). METHODS: The postsurgical lesion location of 195 pediatric patients with cerebellar tumors was mapped onto a template brain. Individuals with CCAS were matched to 2 participants without CCAS by sex, age, and lesion volume. Lesion analyses included both a hypothesis-driven evaluation of the cerebellar outflow pathway (deep nuclei and superior cerebellar peduncles) and data-driven multivariate lesion symptom mapping. Lesion-associated networks were evaluated by comparing connectivity patterns between the lesion location of cases with and those without CCAS with resting-state functional connectivity MRI data from large normative adult and pediatric cohorts. RESULTS: CCAS was present in 48 of 195 participants (24.6%) and was strongly associated with cerebellar outflow tract lesions (p < 0.0001). Lesion symptom mapping also highlighted the cerebellar outflow pathway, with peak findings in the fastigial nuclei extending into the inferior vermis. Lesion network mapping revealed that the cerebellar region most associated with CCAS was functionally connected to the thalamic mediodorsal nucleus, among other sites, and that higher connectivity between lesion location and the mediodorsal nucleus predicts CCAS occurrence (p < 0.01). A secondary analysis of 27 participants with mutism revealed similar localization of lesions and lesion-associated networks. CONCLUSION: Lesions of the cerebellar outflow pathway and inferior vermis are associated with major cognitive and affective disturbances after pediatric cerebellar tumor resection, and disrupted communication between the cerebellum and the thalamic mediodorsal nucleus may be important.

Outcomes of a clinical pathway for primary outpatient management of pediatric patients with low-risk febrile neutropenia.

BACKGROUND: Fever and neutropenia is a common reason for nonelective hospitalization of pediatric oncology patients. Herein we report nearly five years of experience with a clinical pathway designed to guide outpatient management for patients who had low-risk features. PROCEDURES: Through a multidisciplinary collaboration, we implemented a clinical pathway at our institution using established low-risk criteria to guide outpatient management of pediatric oncology patients. Comprehensive chart review of all febrile neutropenia episodes was conducted to characterize outcomes of patients with low-risk febrile neutropenia following clinical pathway implementation. RESULTS: Between April 1, 2013, and October 1, 2017, there were 169 cases of febrile neutropenia managed in our Pediatric Oncology Unit. Sixty-seven (40%) of these episodes were defined as low risk and managed either entirely in the outpatient setting (41 episodes, 24%) or with a step-down strategy involving a very brief inpatient stay (26 episodes, 15%). There were no intensive care unit admissions or deaths among the low-risk patients. Of those identified as low risk, seven patients (10%) required subsequent hospitalization during the follow-up period, two for inadequate oral intake, two for persistent fevers, one for cellulitis, one for seizure unrelated to the febrile episode, and one for a positive blood culture. CONCLUSIONS: Following implementation of a clinical pathway, the majority of patients designated as low risk were managed primarily in the outpatient setting without major morbidity or mortality, suggesting that carefully selected low-risk patients can be successfully treated with outpatient management and subsequent admission if warranted.

Quality of life in patients with proton-treated pediatric medulloblastoma: Results of a prospective assessment with 5-year follow-up.

BACKGROUND: To the authors' knowledge, health-related quality of life (HRQOL) outcomes are not well described in patients with medulloblastoma. The use of proton radiotherapy (RT) may translate into an improved HRQOL. In the current study, the authors report long-term HRQOL in patients with proton-treated pediatric medulloblastoma. METHODS: The current study was a prospective cohort HRQOL study of patients with medulloblastoma who were treated with proton RT and enrolled between August 5, 2002, and October 8, 2015. Both child report and parent-proxy report Pediatric Quality of Life Inventory (PedsQL) surveys were collected at baseline during RT and annually thereafter (score range on surveys of 0-100, with higher scores indicating better HRQOL). Patients were dichotomized by clinical/treatment variables and subgroups were compared. Mixed-model analysis was performed to determine the longitudinal trajectory of PedsQL scores. The Student t test was used to compare long-term HRQOL measures with published means from a healthy child population. RESULTS: Survey data were evaluable for 116 patients with a median follow-up of 5 years (range, 1-10.6 years); the median age at the time of diagnosis was 7.6 years (range, 2.1-18.1 years). At baseline, children reported a total core score (TCS) of 65.9, which increased by 1.8 points annually (P<.001); parents reported a TCS of 59.1, which increased by 2.0 points annually. Posterior fossa syndrome adversely affected baseline scores, but these scores significantly improved with time. At the time of last follow-up, children reported a TCS of 76.3, which was 3.3 points lower than that of healthy children (P = .09); parents reported a TCS of 69, which was 11.9 points lower than that of parents of healthy children (P<.001). Increased follow-up time from diagnosis correlated with improved HRQOL scores. CONCLUSIONS: HRQOL scores appear to increase over time after treatment in children treated with proton RT for medulloblastoma but remain lower compared with those of parent-proxy reports as well as published means from a healthy normative sample of children. Additional follow-up may translate into continued improvements in HRQOL. Cancer 2018. © 2018 American Cancer Society.

Posterior fossa syndrome: Review of the behavioral and emotional aspects in pediatric cancer patients.

Medulloblastoma, the most common malignant brain tumor of childhood, occurs in the posterior fossa, the part of the intracranial cavity that contains the brainstem and the cerebellum. The cerebellum is involved in many complex aspects of human behavior and function, and when it is disrupted or insulted, this can lead to significant sequelae in children with posterior fossa tumors. A constellation of impairing and distressing symptoms, including mutism, ataxia/hypotonia, and emotional lability, develops in approximately 25% of children after the surgical resection of posterior fossa tumors. These symptoms may impede treatment and frequently require intervention in order for children to be able to participate in their care. The eventual recovery of speech occurs for most, but with slowly improving dysarthria over many months. Behavioral changes and emotional lability also occur. This phenomenon has been classified differently by different investigators over the past 35 years. For the purposes of this article, the term posterior fossa syndrome is used to refer to the neuropsychiatric and behavioral features that compose this condition. The current review summarizes the development of the clinical understanding of this phenomenon with a focus on near- and long-term psychosocial and psychiatric implications. Also, clinical examples of the presentation, management, and lasting implications of this syndrome are provided. This review is intended to be a resource for clinicians who treat affected children.

Long-term toxic effects of proton radiotherapy for paediatric medulloblastoma: a phase 2 single-arm study.

BACKGROUND: Compared with traditional photon radiotherapy, proton radiotherapy irradiates less normal tissue and might improve health outcomes associated with photon radiotherapy by reducing toxic effects to normal tissue. We did a trial to assess late complications, acute side-effects, and survival associated with proton radiotherapy in children with medulloblastoma. METHODS: In this non-randomised, open-label, single-centre, phase 2 trial, we enrolled patients aged 3-21 years who had medulloblastoma. Patients had craniospinal irradiation of 18-36 Gy radiobiological equivalents (GyRBE) delivered at 1·8 GyRBE per fraction followed by a boost dose. The primary outcome was cumulative incidence of ototoxicity at 3 years, graded with the Pediatric Oncology Group ototoxicity scale (0-4), in the intention-to-treat population. Secondary outcomes were neuroendocrine toxic effects and neurocognitive toxic effects, assessed by intention-to-treat. This study is registered at ClinicalTrials.gov, number NCT00105560. FINDINGS: We enrolled 59 patients from May 20, 2003, to Dec 10, 2009: 39 with standard-risk disease, six with intermediate-risk disease, and 14 with high-risk disease. 59 patients received chemotherapy. Median follow-up of survivors was 7·0 years (IQR 5·2-8·6). All patients received the intended doses of proton radiotherapy. The median craniospinal irradiation dose was 23·4 GyRBE (IQR 23·4-27·0) and median boost dose was 54·0 GyRBE (IQR 54·0-54·0). Four (9%) of 45 evaluable patients had grade 3-4 ototoxicity according to Pediatric Oncology Group ototoxicity scale in both ears at follow-up, and three (7%) of 45 patients developed grade 3-4 ototoxicity in one ear, although one later reverted to grade 2. The cumulative incidence of grade 3-4 hearing loss at 3 years was 12% (95% CI 4-25). At 5 years, it was 16% (95% CI 6-29). Pediatric Oncology Group hearing ototoxicity score at a follow-up of 5·0 years (IQR 2·9-6·4) was the same as at baseline or improved by 1 point in 34 (35%) of 98 ears, worsened by 1 point in 21 (21%), worsened by 2 points in 35 (36%), worsened by 3 points in six (6%), and worsened by 4 points in two (2%). Full Scale Intelligence Quotient decreased by 1·5 points (95% CI 0·9-2·1) per year after median follow-up up of 5·2 years (IQR 2·6-6·4), driven by decrements in processing speed and verbal comprehension index. Perceptual reasoning index and working memory did not change significantly. Cumulative incidence of any neuroendocrine deficit at 5 years was 55% (95% CI 41-67), with growth hormone deficit being most common. We recorded no cardiac, pulmonary, or gastrointestinal late toxic effects. 3-year progression-free survival was 83% (95% CI 71-90) for all patients. In post-hoc analyses, 5-year progression-free survival was 80% (95% CI 67-88) and 5-year overall survival was 83% (95% CI 70-90). INTERPRETATION: Proton radiotherapy resulted in acceptable toxicity and had similar survival outcomes to those noted with conventional radiotherapy, suggesting that the use of the treatment may be an alternative to photon-based treatments.

Psychosocial Assessment as a Standard of Care in Pediatric Cancer.

This paper presents the evidence for a standard of care for psychosocial assessment in pediatric cancer. An interdisciplinary group of investigators utilized EBSCO, PubMed, PsycINFO, Ovid, and Google Scholar search databases, focusing on five areas: youth/family psychosocial adjustment, family resources, family/social support, previous history/premorbid functioning, and family structure/function. Descriptive quantitative studies, systematic reviews, and meta-analyses (n = 149) were reviewed and evaluated using grading of recommendations, assessment development, and evaluation (GRADE) criteria. There is high quality evidence to support a strong recommendation for multifaceted, systematic assessments of psychosocial health care needs of youth with cancer and their families as a standard of care in pediatric oncology.

Prospective study of health-related quality of life for children with brain tumors treated with proton radiotherapy.

PURPOSE: We describe the health-related quality of life (HRQoL) of a cohort of children with brain tumors treated with proton radiotherapy. PATIENTS AND METHODS: We recruited 142 pediatric patients with brain tumors (age 2 to 18 years) and parents of such patients treated with proton radiation at Massachusetts General Hospital from 2004 to 2010. HRQoL was assessed using the PedsQL core, brain tumor, and cancer modules (range, 0 to 100). Assessments took place during radiation and annually thereafter. We examined correlations of HRQoL with disease, treatment, and cognitive and behavioral data. RESULTS: Overall reports of HRQoL during treatment were 74.8 and 78.1 for child self-report (CSR) and 67.0 and 74.8 for parent proxy report (PPR) for the core and brain tumor modules, respectively. PPR demonstrated lower HRQoL scores than CSR, but the two were highly correlated. Higher HRQoL scores were significantly associated with Wechsler Full Scale Intelligence Quotient scores (administered via the age-appropriate version) and better scores on two behavioral measures. Disease type also correlated with PPR core total HRQoL score at the beginning of treatment: medulloblastoma or primitive neuroectodermal tumors, 57.8; germ cell tumors, 63.5; ependymoma or high-grade glioma, 69.8; low-grade glioma, 71.5; and other low-grade neoplasms, 78.0 (P = .001). Craniospinal irradiation and chemotherapy were negatively correlated with HRQoL. CONCLUSION: This is the first study to our knowledge of HRQoL in a cohort of children with brain tumors treated with proton radiation. This prospective study demonstrates the effect of disease type and intensity of treatment on HRQoL. It further suggests that where CSR is not possible, PPR is appropriate in most circumstances.

Psychiatric aspects of pediatric cancer.

The diagnosis and treatment of children and adolescents with cancer has a tremendous and lasting effect on the patients, their families, and other individuals in their social network. It carries a host of psychological and behavioral ramifications, from questions of mortality to changes in levels of functioning in multiple domains. In this review the authors address the psychosocial and treatment-related issues that arise in children with cancer, with attention to the adjustment to cancer at different developmental stages, mood and anxiety issues, treatment-related psychiatric sequelae, and the challenges faced by childhood cancer survivors.

Psychosocial issues in adolescents with cancer.

Cancer in adolescents is uncommon and when it occurs raises a number of unique challenges for both the patient and their families. Adolescence is a period of time of significant physical and emotional changes and a diagnosis of cancer during this time has a major impact on their psychological and physical development. In this review we will look at the psychosocial issues facing adolescents who have cancer. We will address adolescent development, issues related to informed consent and assent, initial responses to the diagnosis of cancer, quality of life and the experience of the adolescent with cancer, psychological adjustment, support systems, body image issues, sexuality, education, hope, and treatment compliance.

Psychopharmacology in pediatric critical care.

Psychopharmacologic treatment in pediatric critical care requires a careful child or adolescent psychiatric evaluation, including a thorough review of the history of present illness or injury, any current or pre-existing psychiatric disorder, past history, and laboratory studies. Although there is limited evidence to guide psychopharmacologic practice in this setting, psychopharmacologic treatment is increasing in critical care, with known indications for treatment, benefits, and risks; initial dosing guidelines; and best practices. Treatment is guided by the knowledge bases in pediatric physiology, psycho-pharmacology, and treatment of critically ill adults. Pharmacologic considerations include pharmacokinetic and pharmcodynamic aspects of specific drugs and drug classes, in particular elimination half-life, developmental considerations, drug interactions, and adverse effects. Evaluation and management of pain is a key initial step, as pain may mimic psychiatric symptoms and its effective treatment can ameliorate them. Patient comfort and safety are primary objectives for children who are acutely ill and who will survive and for those who will not. Judicious use of psychopharmacolgic agents in pediatric critical care using the limited but growing evidence base and a clinical best practices collaborative approach can reduce anxiety,sadness, disorientation, and agitation; improve analgesia; and save lives of children who are suicidal or delirious. In addition to pain, other disorders or indications for psychopharmacologic treatment are affective disorders;PTSD; post-suicide attempt patients; disruptive behavior disorders (especially ADHD); and adjustment, developmental, and substance use disorders. Treating children who are critically ill with psychotropic drugs is an integral component of comprehensive pediatric critical care in relieving pain and delirium; reducing inattention or agitation or aggressive behavior;relieving acute stress, anxiety, or depression; and improving sleep and nutrition. In palliative care, psychopharmacology is integrated with psychologicapproaches to enhance children's comfort at the end of life. Defining how best to prevent the adverse consequences of suffering and stress in pediatric critical care is a goal for protocols and for new psychopharmacologic research [23,153].

Fluoxetine pharmacokinetics in pediatric patients.

The objective of this study was to evaluate the pharmacokinetic profile of fluoxetine (FLX) and its major metabolite, norfluoxetine (NORFLX), in children and adolescent patients undergoing psychiatric treatment. Twenty-one pediatric subjects--10 children (6-12 years) and 11 adolescents (13-18 years)--were administered 20 mg FLX for 60 days, with sparse blood samples taken throughout the open-label study. Subjects contributed 168 plasma concentrations. Pharmacokinetic parameters were estimated using a mixed effects nonlinear model. Mean steady-state FLX and NORFLX of 127 ng/mL and 151 ng/mL, respectively, were achieved in children and adolescents after 4 weeks of treatment, with high between-patient variability. FLX was 2-fold higher and NORFLX was 1.7-fold higher in children relative to adolescents; however, when normalized to body weight, FLX and NORFLX were similar for both age groups. Age, body weight, body mass index, and body surface area, modeled independently as continuous variables, significantly improved the population pharmacokinetic model when evaluated as patient factors. Body weight was the covariate retained in the final model. In conclusion, children have 2-fold higher FLX and NORFLX relative to adolescents that appear to be related to indices of body size. The accumulation profile and steady-state concentrations in adolescents appear similar to those in adults.
