Pharmacogenetics of drugs in breast cancer and new approaches for improvement of their bioavailability
Abstract
This review analyzed Russian and international studies focusing on the pharmacogenetic approach to treatment of breast cancer. Also, the authors presented results of clinical studies, which showed the role of molecular genetic markers in the efficacy of breast cancer therapy. Allelic variants of different genes have been shown to exert different influences on drug effects. Both inherited and somatic changes in the patient’s genome are pharmacogenetically significant. Inherited genetic variants are generally used for evaluating efficacy and toxicity of drugs while somatic mutations and other known changes in tumor cells are used primarily for selection of treatment and creation of a base for enhancing the effectiveness of therapy. A promising and rapidly developing field of modern pharmacology is targeted delivery of drugs to the tumor. This review summarized state-of-the-art knowledge of new developments in transport of drugs to tumor tissue.
