2002 AUG 8 - (NewsRx.com & NewsRx.net) -- "Predictive Pharmacogenomics: Revolutionizing Health Care," published by Cambridge Healthtech Institute (CHI), examines developing technologies designed to use an individual's genomic profile to predict response to certain drugs, enabling better treatment decisions and safer medical care.
Pharmacogenomic tests are already being used to predict patient response to therapy in the fields of cancer and infectious disease; these two important applications are discussed in detail in this report.
The most notable example in the cancer arena is the testing of breast cancer patients for the presence of estrogen and progesterone receptors in their tumors to predict whether they are likely to respond to hormonal therapy. Breast cancer patients are also tested for overexpression of HER-2/neu before they are given Genentech's Herceptin (trastuzumab), since only those patients whose tumors overexpress HER-2/neu will respond to this therapy.
The fields of antiviral, antibacterial, and antifungal therapy are faced with a different issue - the growing problem of microbial drug resistance, and the need to be able to predict which antimicrobial agents are likely to be effective in treating specific infections. Viral resistance is a major problem in treating HIV infection. Both types of HIV drug-resistance assays-genotyping assays and phenotyping ...
