Cancer Genetic Testing in Ethnic Populations
Study Details
Study Description
Brief Summary
This study examines the integration of cancer genetic testing in various ethnic populations. Studying individuals and families at risk of cancer may help identify cancer genes and other persons at risk. The information from this study may provide an opportunity for cancer risk stratification and individualized screening in these ethnic populations.

Detailed Description
PRIMARY OBJECTIVE:
- To determine the prevalence of genetic mutations in cancer patients from various ethnic populations seeking care at Mayo Clinic Arizona cancer clinics.
SECONDARY OBJECTIVES:
- Perform a chart review to assess the impact of genetic testing as part of standard of oncology care:
Ia. Determine prevalence of pathogenic germline mutation detected by multi-gene panel testing.
Ib. Determine differences in germline mutation detection in these patients as compared to traditional guideline (National Comprehensive Cancer Network [NCCN]) based approach for genetic evaluation.
OUTLINE:
Patients undergo collection of blood or saliva sample for genetic testing.

Outcome Measures
Primary Outcome Measures
- Prevalence of pathogenic germline mutations in enrolled patients within each cancer site [Study 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 mutations [Study 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 criteria [Study 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 prevention [Study 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.
