pharmacogenomics
Pronunciation: FAR-ma-co-GEE-no-mics
The study of how genetic variants influence individual responses to cancer therapeutics.
Full Definition
Pharmacogenomics examines the relationship between genomic variations and drug metabolism, efficacy, and toxicity profiles in cancer treatment. This field combines pharmacology and genomics to optimize therapeutic selection and dosing based on patient-specific genetic profiles. In oncology informatics, pharmacogenomic data integration supports clinical decision-making through automated alerts and dosing recommendations. Key applications include CYP enzyme variant testing for chemotherapy metabolism and HLA typing for immunotherapy toxicity prediction.
