Clinical Trial Summary
Hereditary cancer programs face challenges with respect to effective communication of genetic
test results within families and uptake of genetic testing by relatives. This study aims to
determine if a "disclosure toolkit" provided to the index participant (carrier of cancer risk
gene mutation) contributes to sharing genetic test results with relatives, if there are
preferred disclosure methods, and whether toolkit use contributes towards at-risk relatives
pursuing genetic testing.
Description:
The identification of a single individual with a highly penetrant cancer susceptibility gene
mutation can have far reaching implications for at-risk relatives in that other family
members can engage in highly informative and predictive genetic testing for cancer
predisposition. Family members who carry the familial cancer gene mutation are able to
receive personalized cancer risk management based upon their positive test result, while
those family members who test negative can generally be downgraded to follow cancer screening
guidelines for the general population, barring additional familial or personal risk factors
for developing cancer. Though crucial for stratifying and managing risks for relatives,
familial testing, otherwise known as cascade testing, is not always successfully implemented
within and across families. On a clinical basis the proband, also known as the index mutation
carrier, is generally encouraged to share results with family members in order to promote
their engagement in genetic counseling and testing. Despite the provision of results and a
tailored letter for family members, hereditary cancer programs routinely face challenges with
respect to communication of results within families and uptake of testing by relatives.
Research on family communication and cascade testing substantiates this experience as
previous studies have demonstrated suboptimal uptake of cascade testing in families, despite
its importance for defining and managing cancer risk (Barsevicket al,2008; Daly et al, 2016).
The purpose of our research study is to determine whether the provision of multiple
communication tools and platforms will improve communication between probands and at-risk
relatives, and if so, which communication method is the most useful to probands in
communicating their results and to relatives in coming to a decision regarding genetic
counseling and testing. Through the study, probands will be provided with a three-part
toolkit that includes a letter, website, and a chatbot known as "GIA" (for"Genetic
Information Assistant"). Though the challenges/barriers of cascade testing are
well-documented, there are scant reports of follow-up with relatives. Our study allows direct
contact with family members (by way of proband consent) to assess motivations and barriers to
genetic testing by family members.
