[Molecular markers in ovarian cancer]

Within past few years, the investigation of molecular genetic markers has had an increasing influence on clinical decisions about initial treatment and follow-up. This review presents data concerning the most studied and interesting molecular markers in ovarian cancer. p53 tumour suppressor gene, Bcl-2 oncogene, K-ras oncogene, c-erb2 proto oncogene, c-myc oncogene are examples of currently used molecular genetic markers. Some of these markers might be useful adjuncts for monitoring response to therapy, including early detection of tumour reactivation to allow curative therapy and rapid detection of treatment failure. The study of these markers may also lead to a better understanding of the biological characteristics of ovarian cancer. The information derived from studies of these markers also represents the most promising avenue towards new treatment strategies.
