Inaugural International Adolescent and Young Adult Oncology Congress 2015

18/1/2016

0 Comments

 
From the 3rd-5th December 2015, CanTeen held the inaugural International Adolescent and Young Adult (AYA) Oncology Congress in Sydney. ‘Crossing Boundaries and Bringing it all Together’ was the theme for the congress, highlighting the importance of multidisciplinary research and practice for the delivery of a comprehensive model of care for AYAs. As a testament to this, the congress was well-attended by more than 250 international delegates, from broad backgrounds including oncology and haematology, nursing, and allied health.
​
The Behavioural Sciences Unit was well represented, presenting across all three congress themes of AYA cancer care: best practice and emerging medical treatments, psychological and emotional support, and survivorship.


Associate Professor Claire Wakefield: Genetics-related information needs of AYAs

​A/Prof Wakefield presented findings from recent surveys and interviews with AYA survivors of childhood cancer concerning their genetics-related information needs, as well as recommendations for comprehensive, multidisciplinary care. 

​Dr Ursula Sansom-Daly: Health-literacy and health communication, distress, end-of-life care, and online interventions for AYAs
​
Dr Sansom-Daly presented on a number of her ongoing research projects. The first related to the experiences AYAs with cancer concerning health literacy and health-related communication, ending with a discussion of the implications for the delivery of AYA-friendly care. Dr Sansom-Daly also introduced a tool developed by a research team in the US for AYA cancer patients nearing end-of-life, called ‘Voicing My CHOiCES’, and discussed a study evaluating the potential usefulness of this tool in the Australian context.

 Her next presentation offered insight into the implications of autobiographical disruption and distress mechanisms on tailoring evidence-based support for AYAs with cancer. Dr Sansom-Daly’s final presentation for the congress touched on the ethical and clinical challenges faced when implementing online psychosocial support for AYAs with cancer. ​


Alistair Lum: Educational models

​Mr Lum’s presentation included insights into AYAs perspectives on the importance of positive, supportive teacher attitudes in promoting successful engagement and participation at school.

​Eden Robertson: Romantic relationships and sexual functioning

Ms Robertson presented qualitative findings of AYAs’ perspectives on their romantic and sexual relationships early post-treatment. She highlighted  that while some AYAs are resilient, others do experience sexual and relationship difficulties self-attributed to their cancer experience. This study has recently been accepted for publication in the Journal of Adolescent and Young Adult Oncology.

​
​Professor Richard Cohn: Survivorship care

On the last day of the congress Professor Cohn highlighted the ongoing health challenges faced by many survivors of childhood cancer beyond ‘cure’, as evidence by their increased likelihood of developing cardiovascular disease later in life due to the vascular damage that cancer treatment can cause.

The Impact of Genetic Testing on Children: What do we know, what’s missing?

Genetics research often pushes the boundaries of science, and by the far-reaching nature of genetic information, pushes us out of our comfort zones to consider new psychosocial, ethical, and legal scenarios. Conducting genetic testing on children arguably pushes our boundaries most. Yet, there can be medical benefits for some children, who may then be offered tailored medical care to match their risks. Children can also be indirectly affected by genetic testing, when they learn genetic information about themselves because a family member has had a genetic test.

We reviewed the literature to assess the psychological impact on children who have a genetic test for a heritable condition or who learn genetic information because a family member has a genetic test. You can read the article in Genetics in Medicine. There was surprisingly little data available, with only 13 studies of less than 1000 children, affected by varied conditions, across all age-groups, published worldwide. Serious anxiety, depression and distress was rare: children’s well-being was fairly stable before and after testing, and when compared with peers. Some children did experience serious difficulties though, and a substantial group experienced specific problems (for example, worrying more about their health than other children).

We also reviewed relevant clinical guidance, which warns of many potential problems, including exposing children to potential discrimination (e.g., in education, insurance, employment), guilt and self-blame, family disruptions and social isolation [1]. There were also concerns about incidental findings (where the test finds an unexpected health threat, causing unanticipated distress) and about testing for conditions for which there is no effective intervention before adulthood. Ethical/legal concerns about protecting the child’s privacy and their right not to know (RNTK) are also important [2]. In the case of children, their RNTK may go one step further, to possibly having a right not to even be made aware of potential genetic risks during early childhood. There are also questions about children’s understanding of genetic information, given that many adults struggle to understand the complexities of heredity and genetics.

The lack of hard data on severe negative impacts stands in contrast to the available clinical and ethical guidance. This lack of negative findings may reflect children’s resilience in genetic testing; most adults who have a genetic test seem to adapt well in the long term [3]. Alternatively, research to date may have measured the wrong things. Studies have focussed on ‘traditional’ outcomes (anxiety and depression), and do not explore the unique experiences of learning genetic information in childhood. Also, given that the studies needed parental consent for the child’s participation, families experiencing problems might not have consented and wouldn’t be represented in the findings. Other parents completed proxy measures on their children’s behalf, and we know that parents’ reports do not match their children’s. Most studies also did not follow children long term: as they grow through adolescence, choose a life partner and consider starting a family (time-points which may trigger new concerns about their genetic status). There are also many tests which have not been studied at all, including the ‘brave new world’ of genomic testing.

We do not yet have enough evidence to guide policy surrounding genetic testing and children. Despite more than 20 years of genetic testing, too little data is available on children. This research is hard to do. Clinicians, researchers and ethics boards can be nervous to include children in research and have difficulties choosing the right research questions, the right timing of assessments, and the right research design. It is also unlikely that studies will secure a fully representative sample when parental consent is (rightly) needed for children’s participation.

Until more data becomes available, it is too early to declare genetic testing ‘safe’ for children. Genetic testing should be considered only in cases where there is clear medical benefit to outweigh potential harms [2]. With increasing availability of new screening and intervention measures which are not yet fully evaluated, even deciding whether there is a potential medical benefit can be difficult. These factors are therefore best weighed up with experienced healthcare professionals providing support to the whole family. Escalating genetics research investment means that genetic tests will be considered for growing numbers of children. It is therefore critical to continue the conversation about the psychological, ethical and legal implications of placing children in a situation where they learn genetic information before they are able to give fully informed, independent consent.
