Abstract C086: Somatic mutation variations in minority populations at the University of New Mexico Comprehensive Cancer Center

Abstract The global burden of cancer underscores the urgency to understand its genetic underpinnings. Genetic testing has revolutionized clinical practice, identifying driver mutations crucial for tumorigenesis, including TP53, PIK3CA, KRAS, PTEN, and ARID1A. However, minority populations are underrepresented in major genomic projects, hindering tailored therapies. Variations in genetic polymorphisms among ethnicities, exemplified by distinct patterns in mutations like BRCA and EGFR, underscore the imperative for diversity in genomic research. We conducted a retrospective study at the University of New Mexico Comprehensive Cancer Center, analyzing 5,045 patients' genetic testing data. Significant differences in somatic gene mutation frequencies and survival outcomes were observed across racial and ethnic groups, highlighting the importance of personalized approaches in cancer care. Specific gene mutations, such as IDH1, JAK2, KITX11, and TP53, were associated with distinct survival outcomes. Integrating genetic testing into routine practice could enhance patient stratification and treatment efficacy. Future research should explore underlying mechanisms and include larger, diverse populations to advance personalized medicine in oncology.
