Cancer Genetic Testing in Ethnic Populations

This study is looking at how cancer genetic testing can be used in different ethnic groups. If you have been diagnosed with a solid tumor cancer (like breast, digestive, or brain cancer) and are receiving care at Mayo Clinic in Arizona or Florida, you might be able to join. The study involves collecting a blood sample for genetic testing. Researchers want to find out how common certain genetic changes are in cancer patients from various ethnic backgrounds. This information could help doctors better understand cancer risks and personalize screening for these populations.

Study design
This is an interventional study planning to enroll 1800 participants. It is not specified if it is randomized or blinded.
What's involved
You would provide a blood or saliva sample for genetic testing. The study completion is expected in 2 years.
Compensation
Not stated in the trial record.
Follow-up
The primary outcomes will be measured at the study's completion, which is 2 years.

Eligibility criteria

Inclusion

Patients at least 18 years of age
Individuals diagnosed with any solid tumor cancer including, but not limited to, gastrointestinal, breast, gynecological, genitourinary, skin, central nervous system (CNS)/brain, head/neck, musculoskeletal or cancer of unknown primary; and presenting to Mayo Clinic (MC Arizona or MC Florida) for clinical management/treatment; and patients receive genetic testing as described above
Self-identified as being from various ethnic populations including Hispanic/Latino, Native American/Alaskan, African American (including of African descent), Asian and other European populations
Blood collection is feasible (health, access and/or tolerability) for requested blood sample(s)
Individuals have agreed to participate and signed the study informed consent form

Exclusion

Patients who have had prior germline genetic testing involving a 40+ gene panel within the last 24 months at Mayo Clinic and available for review by the research coordinator at time of consent
Past or current history of hematological cancer (including leukemias, multiple myeloma)
All bone marrow transplants
  • Prevalence of pathogenic germline mutations in enrolled patients within each cancer siteStudy completion (2 years)

    Will identify the prevalence of pathogenic germline mutations in enrolled patients within each cancer site, age (\< 60 years old versus (vs.) \>= 60 years old), and stage (early vs. advanced) via descriptive statistics.

  • Prevalence of positive pathogenic germline mutationsStudy completion (2 years)

    Will determine whether the prevalence of positive pathogenic germline mutations differs between cancer sites, age of diagnosis, and stage of diagnosis using logistic regression analysis across all cancer site groups and pairwise post-hoc analyses using Tukey's correction for multiple comparisons across pairs of cancer sites and chi-square tests of differences between age and stage groups.

  • Rate of mutation detection via genetic testing to clinical practice guidelines of traditional family history criteriaStudy completion (2 years)

    Will compare the rate of mutation detection via genetic testing to clinical practice guidelines of traditional family history criteria within cancer site, age, and stage using logistic regression and pairwise post-hoc analyses as needed.

  • Impact of germline genetic testing on both therapeutic management and targeted cancer preventionStudy completion (2 years)

    Will assess the impact of germline genetic testing on both therapeutic management and targeted cancer prevention in family members using logistic regression and pairwise post-hoc analyses as needed.
