When genetics and pediatric cancer collide: Understanding and optimizing families' experiences.

Background: Advances in our understanding of the genetic basis of childhood cancer, including primary central nervous system cancers, are improving the diagnosis, treatment, and clinical management of pediatric patients. To effectively translate scientific breakthroughs into enhanced clinical care, it is essential we understand and learn from the experiences of patients, families, and health professionals. Methods: This report summarizes findings from 4 Australian psychosocial substudies exploring the perspectives of patients, parents, clinicians, and scientists participating in research related to childhood cancer genetics. Specifically, these studies focus on the psychosocial impact of germline testing in children, surveillance for children with a cancer predisposition syndrome and the perspectives of healthcare professionals who deliver this testing and surveillance. Results: Data presented highlight some of the opportunities and challenges associated with the changing context of genetic predisposition testing for children, adolescents and yound adults with cancer and illustrate how embedding psychosocial data collection in clinical research can answer important questions in the field and inform the design of patient-centric models of care, resources, and workforce training. Conclusions: By embracing these perspectives, we can ensure that advances in genetic research translate into enhanced family experiences, and, ultimately, improved outcomes for children and young people with cancer, and their families.

Barriers to access of precision guided therapies for children with high-risk cancer.

INTRODUCTION: Accessing compassionate access schemes to obtain novel therapeutic agents for children with hard-to-treat cancers can be fraught with challenges such as regulatory barriers and limited resources. This study aimed to explore clinician perspectives on the barriers, impacts and ethical considerations of accessing novel therapeutic agents within the context of a paediatric oncology precision medicine trial. METHODS: We gathered data from 37 semi-structured interviews with paediatric oncologists participating in the PRecISion Medicine for Children with Cancer (PRISM) study, a precision medicine clinical trial in Australia. The interviews, conducted over 2 years, focused on paediatric oncologist's experiences with the PRISM trial. Interviews were re-analysed to identify themes related to access pathways and any challenges in obtaining novel agents through thematic analysis. The resulting thematic framework was discussed and refined by a multidisciplinary team. RESULTS: Three main themes were identified: (i) barriers to access, including poor drug availability, lack of evidence and the time burden of the application process; (ii) impacts of inaccessibility, encompassing medical consequences and financial burden on families; and (iii) ethical considerations, centred around balancing realistic expectations and providing compassionate care to patients and families. Paediatric oncologists expressed frustration with the complex regulatory landscape and the lack of systematic reporting on applications and outcomes of obtaining novel agents. Lengthy wait times for decision notifications were also highlighted, raising concerns about missed therapeutic opportunities for patients. CONCLUSION: This study provides insight to the challenges faced when seeking access to novel therapies for paediatric oncology patients. There is a clear need for improved communication, streamlining processes and increased resources to facilitate access to novel agents. Further resource development is necessary to address these complexities in accessing novel therapy agents to ultimately ensure equitable and timely access.

Promise and Perils of Precision Oncology for Patients With Pediatric and Young Adult Sarcomas.

The completion of multiple national pediatric precision oncology platform trials and the incorporation of standardized molecular profiling into the diagnostic care of pediatric and young adult patients with sarcomas have proven the feasibility and potential of the approach. In this work, we explore the current state of the art of precision oncology for pediatric and young adults with sarcoma. We highlight important lessons learned and the challenges that should be addressed in the next generation of trials. The chapter outlines current efforts to improve standardization of molecular assays, harmonization of data collection, and novel molecular tools such as cell-free DNA analyses. Finally, we discuss the impacts and psychosocial outcomes experienced by patients and communication strategies for providers.

The feasibility and acceptability of collecting psychosocial outcome measures embedded within a precision medicine trial for childhood cancer.

BACKGROUND: Patient-reported outcomes measures (PROMs) are increasingly being collected within cancer clinical trials, yet limited literature on the feasibility and acceptability of doing so. METHODS: We collected parent-proxy and adolescent (≥12 years old) PROMs through a longitudinal, psychosocial sub-study ('PRISM-Impact') embedded in a precision medicine trial for children with poor prognosis cancer ('PRISM'). We report on feasibility (response, participation, and attrition rates; follow-up and responding to elevated distress) and acceptability (parents' perceived benefit/burden of participation; and impact on decision to participate in PRISM) of PRISM-Impact. RESULTS: Over the reporting period, 462 families were eligible for PRISM-Impact. Family and adolescent response rates were 53% and 45%, respectively. Parents whose child had relapsed were more likely to participate in PRISM-Impact than parents whose child had not (p < 0.001). Parent and adolescent attrition rates were 30% and 56% respectively. We conducted 478 calls for intake and to follow-up on missing questionnaires, and 122 calls to respond to elevated distress. Parents reported wanting to participate in PRISM-Impact for altruistic reasons and because they valued psychosocial research. Parents reported little-to-no burden and some benefit from participating in PRISM-Impact, with little change in ratings overtime. Most parents felt that participating in PRISM-Impact did not impact their desire to participate in PRISM (72%), with some feeling more eager to participate (19%). CONCLUSIONS: PRISM-Impact response rates were comparable to other psycho-oncology studies, despite the poor prognosis population. Integration of PROMs within a paediatric oncology trial is acceptable to parents, and may provide a more comprehensive assessment of the impact of trial participation.

Parents' and patients' perspectives, experiences, and preferences for germline genetic or genomic testing of children with cancer: A systematic review.

PURPOSE: Germline testing in pediatric cancer presents opportunities and challenges. Understanding family perspectives, experiences, and preferences will optimize integration into routine care. METHODS: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we searched 4 databases for studies exploring perspectives, experiences, and preferences of parents/caregivers and/or patients regarding germline testing of children with cancer. Qualitative and quantitative data were extracted, organized, and summarized by research question and themes. RESULTS: We identified 2286 unique articles, of which 24 were included. Interest in and uptake of testing was high. Families were motivated by altruism and a desire for inheritance/causation information. Testing barriers included psychological concerns, timing of the testing approach if offered at diagnosis or in a high-risk cancer setting and privacy/discrimination. Testing experiences highlighted challenges yet also positive impacts, with results providing psychological relief and informing proactive decision making. Timing preferences varied; however, allowing time to adjust to a new diagnosis was a common theme. Most wanted to receive as many germline sequencing-related results as possible. CONCLUSION: Findings underscore the importance of integrating germline analyses into pediatric cancer care with flexibility and support for families facing challenges. Where possible, consent should be provided at a time that suits each family's situation with access to information aligning with their needs and preferences. PROSPERO: CRD42023444890.

It provides families with other avenues for treatment when there are no other options Surgeons' perspectives of being part of a precision medicine trial for poor prognosis paediatric cancer patients: A short report.

OBJECTIVE: Precision medicine is transforming cancer treatment, yet the perspectives of surgeons who often play a critical role in the delivery of precision medicine remain understudied. METHODS: We conducted semi-structured interviews with 13 surgeons involved in a precision medicine trial for children with poor prognosis cancer. We explored knowledge of genetics, confidence with somatic and germline results, ratings of benefit to stakeholders and willingness to undertake surgical procedures. RESULTS: Surgeons generally had positive attitudes towards precision medicine but expressed concerns about families' unrealistic expectations, mixed opinions on the benefits and the use of research-only biopsies. Most surgeons rated their genetics knowledge as 'good' (69%) and felt 'very confident' in identifying genetic specialists (66%), but 'not confident' (66.6%) in making treatment recommendations. Surgeons' willingness to undertake a procedure was influenced by potential patient benefit. CONCLUSIONS: Our findings support the need for more workforce and training support for surgeons to fully engage with precision medicine.

'High hopes for treatment': Australian stakeholder perspectives of the clinical translation of advanced neurotherapeutics for rare neurological diseases.

INTRODUCTION: Advanced therapies offer unprecedented opportunities for treating rare neurological disorders (RNDs) in children. However, health literacy, perceptions and understanding of novel therapies need elucidation across the RND community. This study explored healthcare professionals' and carers' perspectives of advanced therapies in childhood-onset RNDs. METHODS: In this mixed-methodology cross-sectional study, 20 healthcare professionals (clinicians, genetic counsellors and scientists) and 20 carers completed qualitative semistructured interviews and custom-designed surveys. Carers undertook validated psychosocial questionnaires. Thematic and quantitative data analysis followed. RESULTS: Participants described high positive interest in advanced therapies, but low knowledge of, and access to, reliable information. The substantial 'therapeutic gap' and 'therapeutic odyssey' common to RNDs were recognised in five key themes: (i) unmet need and urgency for access; (ii) seeking information; (iii) access, equity and sustainability; (iv) a multidisciplinary and integrated approach to care and support and (v) difficult decision-making. Participants were motivated to intensify RND clinical trial activity and access to advanced therapies; however, concerns around informed consent, first-in-human trials and clinical trial procedures were evident. There was high-risk tolerance despite substantial uncertainties and knowledge gaps. RNDs with high mortality, increased functional burdens and no alternative therapies were consistently prioritised for the development of advanced therapies. However, little consensus existed on prioritisation to treatment access. CONCLUSIONS: This study highlights the need to increase clinician and health system readiness for the clinical translation of advanced therapeutics for RNDs. Co-development and use of educational and psychosocial resources to support clinical decision-making, set therapeutic expectations and promotion of equitable, effective and safe delivery of advanced therapies are essential. PATIENT OR PUBLIC CONTRIBUTION: Participant insights into the psychosocial burden and information need to enhance the delivery of care in this formative study are informing ongoing partnerships with families, including co-production and dissemination of psychoeducational resources featuring their voices hosted on the Sydney Children's Hospitals Network website SCHN Brain-Aid Resources.

Hopes, concerns, satisfaction and regret in a precision medicine trial for childhood cancer: a mixed-methods study of parent and patient perspectives.

BACKGROUND: Paediatric precision oncology aims to match therapeutic agents to driver gene targets. We investigated whether parents and patients regret participation in precision medicine trials, particularly when their hopes are unfulfilled. METHODS: Parents and adolescent patients completed questionnaires at trial enrolment (T0) and after receiving results (T1). Parents opted-in to an interview at T1. Bereaved parents completed a questionnaire 6-months post-bereavement (T1B). We analysed quantitative data with R and qualitative data thematically with NVivo, before integrating all data for interpretation. RESULTS: 182 parents and 23 patients completed T0; 108/182 parents and 8/23 patients completed T1; 27/98 bereaved parents completed T1B; and 45/108 parents were interviewed. At enrolment, participants held concurrent hopes that precision medicine would benefit future children and their child. Participants expressed concern regarding wait-times for receipt of results. Most participants found the trial beneficial and not burdensome, including bereaved parents. Participants reported high trial satisfaction (median scores: parents: 93/100; patients: 80/100). Participants expressed few regrets (parent median scores: parents: 10/100; bereaved parents: 15/100; patient regret: 2/8 expressed minimal regret). CONCLUSIONS: Even when trial outcomes did not match their hopes, parents and patients rarely regretted participating in a childhood cancer precision medicine trial. These data are critical for integrating participants' views into future precision medicine delivery.

Precision Medicine Is Changing the Roles of Healthcare Professionals, Scientists, and Research Staff: Learnings from a Childhood Cancer Precision Medicine Trial.

Precision medicine programs aim to utilize novel technologies to identify personalized treatments for children with cancer. Delivering these programs requires interdisciplinary efforts, yet the many groups involved are understudied. This study explored the experiences of a broad range of professionals delivering Australia's first precision medicine trial for children with poor-prognosis cancer: the PRecISion Medicine for Children with Cancer (PRISM) national clinical trial of the Zero Childhood Cancer Program. We conducted semi-structured interviews with 85 PRISM professionals from eight professional groups, including oncologists, surgeons, clinical research associates, scientists, genetic professionals, pathologists, animal care technicians, and nurses. We analyzed interviews thematically. Professionals shared that precision medicine can add complexity to their role and result in less certain outcomes for families. Although many participants described experiencing a greater emotional impact from their work, most expressed very positive views about the impact of precision medicine on their profession and its future potential. Most reported navigating precision medicine without formal training. Each group described unique challenges involved in adapting to precision medicine in their profession. Addressing training gaps and meeting the specific needs of many professional groups involved in precision medicine will be essential to ensure the successful implementation of standard care.

Parents' expectations, preferences, and recall of germline findings in a childhood cancer precision medicine trial.

BACKGROUND: Germline genome sequencing in childhood cancer precision medicine trials may reveal pathogenic or likely pathogenic variants in cancer predisposition genes in more than 10% of children. These findings can have implications for diagnosis, treatment, and the child's and family's future cancer risk. Understanding parents' perspectives of germline genome sequencing is critical to successful clinical implementation. METHODS: A total of 182 parents of 144 children (<18 years of age) with poor-prognosis cancers enrolled in the Precision Medicine for Children with Cancer trial completed a questionnaire at enrollment and after the return of their child's results, including clinically relevant germline findings (received by 13% of parents). Parents' expectations of germline genome sequencing, return of results preferences, and recall of results received were assessed. Forty-five parents (of 43 children) were interviewed in depth. RESULTS: At trial enrollment, most parents (63%) believed it was at least "somewhat likely" that their child would receive a clinically relevant germline finding. Almost all expressed a preference to receive a broad range of germline genomic findings, including variants of uncertain significance (88%). Some (29%) inaccurately recalled receiving a clinically relevant germline finding. Qualitatively, parents expressed confusion and uncertainty after the return of their child's genome sequencing results by their child's clinician. CONCLUSIONS: Many parents of children with poor-prognosis childhood cancer enrolled in a precision medicine trial expect their child may have an underlying cancer predisposition syndrome. They wish to receive a wide scope of information from germline genome sequencing but may feel confused by the reporting of trial results.

Parents' and adolescents' perspectives and understanding of information about childhood cancer precision medicine.

BACKGROUND: Precision medicine is projected to become integral to childhood cancer care. As such, it is essential to support families to understand what precision medicine entails. METHODS: A total of 182 parents and 23 adolescent patients participating in Precision Medicine for Children with Cancer (PRISM), an Australian precision medicine clinical trial for high-risk childhood cancer, completed questionnaires after study enrollment (time 0 [T0]). Of the parents, 108 completed a questionnaire and 45 completed an interview following return of precision medicine results (time 1 [T1]). We analyzed the mixed-methods data comprising measures exploring families' perceptions and understanding of PRISM's participant information sheet and consent form (PISCF), and factors associated with understanding. RESULTS: Most parents were satisfied with the PISCF, rating it as at least "somewhat" clearly presented (n = 160/175; 91%) and informative (n = 158/175; 90%). Many suggested improvements including the use of clearer language and a more visually engaging format. Parents' actual understanding of precision medicine was low on average, but scores improved between T0 and T1 (55.8/100-60.0/100; p = .012). Parents from culturally and/or linguistically diverse backgrounds (n = 42/177; 25%) had lower actual understanding scores than those from a Western/European background whose first language was English (p = .010). There was little correlation between parents' perceived and actual understanding scores (p = .794; Pearson correlation -0.020; 95% CI, -0.169 to 0.116). Most adolescent patients read the PISCF either "briefly" or "not at all" (70%) and had a perceived understanding score of 63.6/100 on average. CONCLUSIONS: Our study revealed gaps in families' understanding of childhood cancer precision medicine. We highlighted areas for potential intervention such as through targeted information resources. PLAIN LANGUAGE SUMMARY: Precision medicine is projected to become part of the standard of care for children with cancer. Precision medicine aims to give the right treatment to the right patient and involves several complex techniques, many of which may be challenging to understand. Our study analyzed questionnaire and interview data from parents and adolescent patients enrolled in an Australian precision medicine trial. Findings revealed gaps in families' understanding of childhood cancer precision medicine. Drawing on parents' suggestions and the literature, we make brief recommendations about improving information provision to families, such as through targeted information resources.

Protocol for a comprehensive prospective cohort study of trio-based whole-genome sequencing for underlying cancer predisposition in paediatric and adolescent patients newly diagnosed with cancer: the PREDICT study.

INTRODUCTION: Identifying an underlying germline cancer predisposition (CP) in a child with cancer has potentially significant implications for both the child and biological relatives. Cohort studies indicate that 10%-15% of paediatric cancer patients carry germline pathogenic or likely pathogenic variants in cancer predisposition genes, but many of these patients do not meet current clinical criteria for genetic testing. This suggests broad tumour agnostic germline testing may benefit paediatric cancer patients. However, the utility and psychosocial impact of this approach remain unknown. We hypothesise that an approach involving trio whole-genome germline sequencing (trio WGS) will identify children and families with an underlying CP in a timely fashion, that the trio design will streamline cancer risk counselling to at-risk relatives if CP was inherited, and that trio testing will not have a negative psychosocial impact on families. METHOD AND ANALYSIS: To test this, we present the Cancer PREDisposition In Childhood by Trio sequencing study (PREDICT). This study will assess the clinical utility of trio WGS to identify CP in unselected patients with cancer 21 years or younger in New South Wales, Australia. PREDICT will perform analysis of biological parents to determine heritability and will examine the psychosocial impact of this trio sequencing approach. PREDICT also includes a broad genomics research programme to identify new candidate genes associated with childhood cancer risk. ETHICS AND DISSEMINATION: By evaluating the feasibility, utility and psychosocial impact of trio WGS to identify CP in paediatric cancer, PREDICT will inform how such comprehensive testing can be incorporated into a standard of care at diagnosis for all childhood cancer patients. TRIAL REGISTRATION NUMBER: NCT04903782.

Quality of Life (QoL) of Children and Adolescents Participating in a Precision Medicine Trial for High-Risk Childhood Cancer.

Precision medicine is changing the treatment of childhood cancer globally, however little is known about quality of life (QoL) in children and adolescents participating in precision medicine trials. We examined QoL among patients enrolled in PRISM, the Zero Childhood Cancer Program's precision medicine trial for high-risk childhood cancer. We assessed patient QoL via self-report (aged 12-17 years) and parent-proxy (aged 4-17 years) completion of the EQ-5D-Y. We analysed data using descriptive statistics and regression models. Patients (n = 23) and parents (n = 136) provided data after trial enrolment and following receipt of trial results and treatment recommendations (n = 8 patients, n = 84 parents). At enrolment, most patients were experiencing at least some difficulty across more than one QoL domain (81% patient self-report, 83% parent report). We did not find strong evidence of a change in QoL between timepoints, or of demographic or disease factors that predicted parent-reported patient QoL (EQ-VAS) at enrolment. There was strong evidence that receiving a treatment recommendation but not a change in cancer therapy was associated with poorer parent-reported patient QoL (EQ-VAS; Mdiff = -22.5, 95% CI: -36.5 to -8.5, p = 0.006). Future research needs to better understand the relationship between treatment decisions and QoL and would benefit from integrating assessment of QoL into routine clinical care.

'Advocacy groups are the connectors': Experiences and contributions of rare disease patient organization leaders in advanced neurotherapeutics.

INTRODUCTION: Biomedical progress has facilitated breakthrough advanced neurotherapeutic interventions, whose potential to improve outcomes in rare neurological diseases has increased hope among people with lived experiences and their carers. Nevertheless, gene, somatic cell and other advanced neurotherapeutic interventions carry significant risks. Rare disease patient organizations (RDPOs) may enhance patient experiences, inform expectations and promote health literacy. However, their perspectives are understudied in paediatric neurology. If advanced neurotherapeutics is to optimize RDPO contributions, it demands further insights into their roles, interactions and support needs. METHODS: We used a mixed-methodology approach, interviewing 20 RDPO leaders representing paediatric rare neurological diseases and following them up with two online surveys featuring closed and open-ended questions on advanced neurotherapeutics (19/20) and negative mood states (17/20). Qualitative and quantitative data were analysed using thematic discourse analysis and basic descriptive statistics, respectively. RESULTS: Leaders perceived their roles to be targeted at educational provision (20/20), community preparation for advanced neurotherapeutic clinical trials (19/20), information simplification (19/20) and focused research pursuits (20/20). Although most leaders perceived the benefits of collaboration between stakeholders, some cited challenges around collaborative engagement under the following subthemes: conflicts of interest, competition and logistical difficulties. Regarding neurotherapeutics, RDPO leaders identified support needs centred on information provision, valuing access to clinician experts and highlighting a demand for co-developed, centralized, high-level and understandable, resources that may improve information exchange. Leaders perceived a need for psychosocial support within themselves and their communities, proposing that this would facilitate informed decision-making, reduce associated psychological vulnerabilities and maintain hope throughout neurotherapeutic development. CONCLUSION: This study provides insights into RDPO research activities, interactions and resource needs. It reveals a demand for collaboration guidelines, central information resources and psychosocial supports that may address unmet needs and assist RDPOs in their advocacy. PATIENT OR PUBLIC CONTRIBUTION: In this study, RDPO leaders were interviewed and surveyed to examine their perspectives and roles in advanced neurotherapeutic development. Some participants sent researchers postinterview clarification emails regarding their responses to questions.

'Like ships in the night': A qualitative investigation of the impact of childhood cancer on parents' emotional and sexual intimacy.

BACKGROUND: Childhood cancer is highly distressing for families and can place strain on parents' relationships. Parental functioning and cohesiveness are important predictors of family functioning and adaptation to stress. This qualitative study investigated the perceived impact of childhood cancer on parents' relationship with their partner, with a focus on emotional and sexual intimacy. METHODS: We conducted semi-structured interviews with 48 parents (42 mothers, six fathers) of children under the age of 18 who had completed curative cancer treatment. We analysed the interviews using thematic analysis. RESULTS: At interview, parents were on average 40.7 years old (SD = 5.5, range: 29-55 years), and had a child who had completed cancer treatment between 3 months and 10.8 years previously (M = 22.1 months). All participants were living with their partner in a married/de facto relationship. Most parents reported that their child's cancer treatment had a negative impact on emotional and sexual intimacy with their partner, with some impacts extending to the post-treatment period. Reasons for compromised intimacy included exhaustion and physical constraints, having a shifted focus, and discord arising from different coping styles. Some parents reported that their relationship strengthened. Parents also discussed the impact of additional stressors unrelated to the child's cancer experience. CONCLUSIONS: Parents reported that childhood cancer had a negative impact on aspects of emotional and sexual intimacy, although relationship strengthening was also evident. It is important to identify and offer support to couples who experience ongoing relationship stress, which may have adverse effects on family functioning and psychological wellbeing into survivorship.

What's in a Name? Parents' and Healthcare Professionals' Preferred Terminology for Pathogenic Variants in Childhood Cancer Predisposition Genes.

Current literature/guidelines regarding the most appropriate term to communicate a cancer-related disease-causing germline variant in childhood cancer lack consensus. Guidelines also rarely address preferences of patients/families. We aimed to assess preferences of parents of children with cancer, genetics professionals, and pediatric oncologists towards terminology to describe a disease-causing germline variant in childhood cancer. Using semi-structured interviews we asked participants their most/least preferred terms from; 'faulty gene,' 'altered gene,' 'gene change,' and 'genetic variant,' analyzing responses with directed content analysis. Twenty-five parents, 6 genetics professionals, and 29 oncologists participated. An equal number of parents most preferred 'gene change,' 'altered gene,' or 'genetic variant' (n = 8/25). Parents least preferred 'faulty gene' (n = 18/25). Half the genetics professionals most preferred 'faulty gene' (n = 3/6); however this was least preferred by the remaining genetics professionals (n = 3/6). Many oncologists most preferred 'genetic variant' (n = 11/29) and least preferred 'faulty gene' (n = 19/29). Participants across all groups perceived 'faulty gene' as having negative connotations, potentially placing blame/guilt on parents/children. Health professionals described challenges selecting a term that was scientifically accurate, easily understood and not distressing to families. Lack of consensus highlights the need to be guided by families' preferred terminology, while providing accurate explanations regarding implications of genetic findings.

Parents' understanding of genome and exome sequencing for pediatric health conditions: a systematic review.

Genome and exome sequencing (GS/ES) are increasingly being used in pediatric contexts. We summarize evidence regarding the actual and perceived understanding of GS/ES of parents of a child offered testing for diagnosis and/or management of a symptomatic health condition. We searched four databases (2008-2021) and identified 1264 unique articles, of which 16 met inclusion criteria. We synthesized data from qualitative and quantitative studies and organized results using Ayuso et al. (2013)'s framework of key elements of information for informed consent to GS/ES. Many of the parents represented had prior experience with genetic testing and accessed a form of genetic counseling. Parents' understanding was varied across the domains evaluated. Parents demonstrated understanding of the various potential direct clinical benefits to their child undergoing GS/ES, including in relation to other genetic tests. We found parents had mixed understanding of the nature of potential secondary findings, and of issues related to data privacy, confidentiality, and usage of sequencing results beyond their child's clinical care. Genetic counseling consultations improved understanding. Our synthesis indicates that ES/GS can be challenging for families to understand and underscores the importance of equipping healthcare professionals to explore parents' understanding of ES/GS and the implications of testing for their child.

Providing Psychological Support to Parents of Childhood Cancer Survivors: 'Cascade' Intervention Trial Results and Lessons for the Future.

We conducted a three-armed trial to assess Cascade, a four-module group videoconferencing cognitive behavior therapy (CBT) intervention for parents of childhood cancer survivors currently aged <18 years. We allocated parents to Cascade, an attention control (peer-support group), or a waitlist. The primary outcome was parents' health-related quality of life (PedsQL-Family Impact/EQ-5D-5L) six months post-intervention. Parents also reported their anxiety/depression, parenting self-agency, fear of recurrence, health service and psychotropic medication use, engagement in productive activities, confidence to use, and actual use of, CBT skills, and their child's quality of life. Seventy-six parents opted in; 56 commenced the trial. Cascade achieved good parent engagement and most Cascade parents were satisfied and reported benefits. Some parents expressed concerns about the time burden and the group format. Most outcomes did not differ across trial arms. Cascade parents felt more confident to use more CBT skills than peer-support and waitlisted parents, but this did not lead to more use of CBT. Cascade parents reported lower psychosocial health scores for their child than waitlisted parents. Cascade parents' health service use, psychotropic medication use, and days engaged in productive activities did not improve, despite some improvements in waitlisted parents. Our trial was difficult to implement, but participants were largely satisfied. Cascade did not improve most outcomes, possibly because many parents were functioning well pre-enrolment. We used these findings to improve Cascade and will trial the new version in future.

Health service and medication use of parents of childhood cancer survivors: a controlled comparison study.

BACKGROUND: Parents of childhood cancer survivors may be vulnerable to experiencing poor health outcomes, but little is known about how these parents use healthcare. This study investigated the nature and extent of survivors' parents' healthcare and medication use relative to a comparison group. We also examined whether demographic or cancer-related factors were related to healthcare use and whether healthcare use was associated with parents' general functioning. METHODS: We conducted a cross-sectional study involving 55 parents of cancer survivors recruited through eight Australian hospitals, and 135 parents of children without a cancer diagnosis, through an online recruitment platform. Participants responded to a questionnaire assessing their health service usage, regular medications, general functioning (engagement activities including work/study) and anxiety and depression symptoms (using PROMIS short forms). We performed regression analysis to determine factors related to healthcare and medication use in parents of survivors. RESULTS: More parents of survivors reported accessing mental health services than comparison parents (56% vs. 33%, p=.003), mainly due to their use of social workers. Fewer parents of survivors reported accessing other community health services, particularly general practitioners (51% vs. 78%, p<.001). Having a child survivor who was male was associated with greater use of community health services (B= -0.67, p=.008). No other demographic or cancer-related variables were associated with health service use. Health service use was not associated with general functioning, but greater medication use was associated with higher anxiety scores (B = 1.41, p=.008). CONCLUSION: Parents of childhood cancer survivors showed different patterns of health service use relative to comparison parents, but the extent of their use was not significantly linked with demographic or cancer-related variables. Comprehensive assessment of parents' needs in clinical encounters remains vital to identify and appropriately match support needs with available services.

How Are Families Faring? Perceived Family Functioning Among Adolescent and Young Adult Cancer Survivors in Comparison to Their Peers.

Purpose: Adolescent and young adult (AYA) cancer survivors' families can face ongoing challenges into survivorship. Families' adjustment and functioning as a unit can subsequently impact AYAs' mental health and quality of life. This study examined AYA cancer survivors' perceived family functioning, compared with their peers, and investigated factors associated with family functioning. Methods: Eligible participants were aged between 15 and 40 years, fluent in English, and cancer survivors who had completed treatment. AYA cancer survivors were recruited from hospital clinics, and the comparison group from an affiliated university campus. Participants completed the McMaster Family Assessment Device, Kidcope, and the Depression, Anxiety and Stress Scale-Short Form. We analyzed between-group differences in family functioning using multivariate analysis of covariance and used partial correlations to investigate associations between demographic cancer-related psychological coping variables and family functioning. Results: Ninety-three AYA cancer survivors and 141 comparison peers participated (ages: 15-32 years). AYA cancer survivors reported significantly better family functioning (p = 0.029), lower depression (p = 0.016), and anxiety symptoms (p = 0.008) compared with the comparison group. Approximately one-third of AYA survivors (34.4%) reported clinically significant maladaptive family functioning; however, this was more prevalent in the comparison group (50.4%). After adjusting for covariates, poorer family functioning was associated with AYA survivors using more avoidant escape-oriented coping strategies (p = 0.010). Conclusions: Our cancer survivor cohort reported better family functioning and psychological outcomes compared with their peers. Interventions targeting avoidant coping behaviors may support improved family functioning in some survivors. Further research disentangling the relationship between coping mechanisms and family functioning among AYA cancer survivors is needed.
