A team of three Japanese researchers has conducted a survey of stakeholders to examine how patient voices impact decisions related to genetic testing for hereditary cancers. These stakeholders included patients, healthcare professionals, and ethicists attending a workshop in Hiroshima in early 2025. The correspondence is published in the\u00a0European Journal of Human Genetics<\/em><\/a>\u00a0on March 15, 2025.<\/p>

\u00a0<\/p>

There are differences of opinion in how to assess \u201cseriousness\u201d in genetic conditions. \u201cIn Japan, the seriousness of genetic disorders has traditionally been assessed using narrow medical criteria, limiting access to preimplantation genetic testing for monogenic diseases to only a small number of conditions. However, cases like retinoblastoma\u2014which was only recognized as \u2018serious\u2019 after six years of patient advocacy\u2014underscore the urgent need to incorporate stakeholder values and lived experiences into these assessments,\u201d said Shizuko Takahashi, a Research Fellow at National University of Singapore. Drawing on a framework proposed by Kleiderman et al., the team conducted a two-stage survey during a stakeholder dialogue event in Hiroshima in January 2025, exploring how the participants\u2019 understanding of \u201cseriousness\u201d evolved in response to patient testimonies and discussion.<\/p>

\u00a0<\/p>

The team used a\u00a0recent review by Kleiderman et al.<\/a>\u00a0as a framework for understanding the multifaceted concept of seriousness in genetic conditions. This framework, published in a recent issue of the\u00a0European Journal of Human Genetics<\/em>, emphasizes the core dimensions and procedural elements of seriousness, offering valuable insights into the Japanese context. Many countries have expanded access to preimplantation genetic testing for monogenic disorders. However, Japan continues to be restrictive, having approved only 17 conditions under the strict criteria set by the Japanese Society of Obstetrics and Gynecology.<\/p>

\u00a0<\/p>

The team conducted their survey in two phases, assessing the participants\u2019 perceptions before and after patient testimonies. First, a clinical geneticist explained the medical criteria for preimplantation genetic testing for monogenic disorders, treatment options, and available support resources. The geneticist addressed core dimensions such as \u201cmedical criteria,\u201d \u201caccess\/availability of treatment,\u201d and \u201caccess\/availability of support and resources.\u201d After that first presentation, individuals with hereditary cancer\u2014including patients with retinoblastoma and BRCA2 mutations\u2014shared their lived experiences. This juxtaposition of medical information with personal narratives allowed participants to reflect on how \u201cindividual and familial lived experiences,\u201d a crucial core dimension, influence their perceptions of seriousness.<\/p>

\u00a0<\/p>

Before hearing patient testimonies, 66% of participants indicated they would consider preimplantation genetic testing for monogenic disorders if faced with hereditary cancer, citing a desire to prevent the inheritance of debilitating conditions. In addition, 89% believed that patients should be informed about preimplantation genetic testing for monogenic disorders at the time of diagnosis, highlighting the importance of access to information.<\/p>

\u00a0<\/p>

However, the participants\u2019 perspectives shifted notably after hearing patient stories.<\/p>

\u00a0<\/p>

The proportion of participants who viewed preimplantation genetic testing for monogenic disorders primarily as a public health tool aimed at reducing the burden on society significantly decreased (p = 0.005). In addition, there was an increased emphasis on individual reproductive autonomy. The participants\u2019 favorable attitudes toward marriage, pregnancy, and family planning with preimplantation genetic testing for monogenic disorders rose from 54% pre-testimony to 71% post-testimony. These shifts highlight how firsthand accounts can recalibrate people\u2019s ideas about \u201cseriousness.\u201d<\/p>

\u00a0<\/p>

\u201cLived experiences profoundly shape how people understand the \u2018seriousness\u2019 of hereditary cancer\u2014and shift perceptions of preimplantation genetic testing for monogenic disorders from a tool of societal burden reduction to one of individual reproductive autonomy,\u201d said\u00a0Rie Iizuka<\/a>, an assistant professor (special recognition) at Hiroshima University. This underscores the urgent need to include patient voices in shaping ethical frameworks and policy decisions around genetic testing.<\/p>

\u00a0<\/p>

The team notes that while this is the first study to examine stakeholder perspectives on preimplantation genetic testing for monogenic disorders in Japan, it has a couple of limitations. First, the sample size was relatively small, and participants were drawn from a preimplantation genetic testing for monogenic disorders-related event, introducing potential selection bias. Second, the definition of stakeholders in this study was limited to individuals affected by hereditary cancer. This excluded those with other genetic conditions. \u201cFuture research will seek to include a broader and more diverse participant pool, both within Japan and internationally. Our aim is to provide empirical support for applying Kleiderman et al.\u2019s argument\u2014that assessments of the seriousness of genetic conditions should meaningfully incorporate stakeholders\u2019 lived experiences\u2014to the criteria guiding the implementation of preimplantation genetic testing for monogenic disorders,\u201d said\u00a0Tsutomu Sawai<\/a>, a professor (special recognition) in ethics at Hiroshima University.<\/p>
