Prof. Hiltrud Brauch came to the Dr. Margarete Fischer-Bosch-Institute of Clinical Pharmacology (IKP) in 1999 after completing her training in Molecular Genetics of Cancer and Habilitation in the field of Molecular Pathology. She has held positions of increasing responsibility at the National Cancer Institute (NCI), USA, the German Cancer Research Center, Heidelberg, the Technical University Munich (Klinikum rechts der Isar), the University of Hamburg, and the IKP Stuttgart.

During her postdoctoral training at the NCI, she was part of the team identifying the VHL Tumor Suppressor Locus and since then pursues a range of scientific interests including the Molecular Origin of Hereditary (VHL disease) and Sporadic Kidney Cancer. Within the last decade she has established a reputation within the field of Breast Cancer Susceptibility and Treatment Outcomes. At IKP she has expanded her research towards a strong focus on the Pharmacogenomics of Breast Cancer.

Prof. Brauch participates in a number of national and international research networks including the Gene Environment Interactions and Breast Cancer in Germany (GENICA), the Breast Cancer Association Consortium (BCAC) and the International Tamoxifen Consortium (ITPC). She coordinated the 5FP EU European Marie Curie PhD training site Stuttgart/Tübingen “Fighting Breast Cancer”, and teaches at the University of Tübingen. Currently she coordinates the 7FP EU Initial Training Network Fighting Drug Failure, which establishes the first European Curriculum in the field of Pharmacogenomics for young investigators.

Scientific accomplishments include more than 150 peer reviewed publications, including more than 220 original research articles.

Contents and Research Group

Can breast cancer risk, disease and drug treatment outcome be explained by genetic variation?

The high morbidity and mortality rates among breast cancer patients are mainly attributed to the lack of known risk factors as well as lack of efficient and non-toxic anti-cancer drugs. To improve women’s health and in particular to improve the quality of life of breast cancer patients, efficient approaches must include strategies for breast cancer prevention and improvement of individual drug therapy and response. My research team, therefore, focuses on the translation of basic research findings towards breast cancer prevention and the improvement of drug therapy, particular endocrine treatment. This involves laboratory and clinical investigations with defined patient collections, including case-control and treatment cohorts by way of candidate gene approaches, which currently focus on variations of drug metabolizing enzymes. This translational research involves a high degree of interdisciplinary collaboration among scientists with clinical, research and statistical expertise for the complex evaluation of clinical and laboratory data obtained via high-throughput molecular analyses.
