Microarray-Based Gene Expression Studies in Ovarian Cancer

Background: DNA microarray technology is a powerful genomic tool that has the potential to elucidate the relationship between clinical features of cancers and their underlying biological alterations. Methods: We performed a systemic search in PubMed and Medline databases for recently published articles. The search terms used included "genome-wide," "microarrays," "ovarian cancer," "prognosis," "gene expression profiling," "molecular marker," and "molecular biomarker." Results: Genome-wide expression profiling using DNA microarray technology has enhanced our understanding of the genes that influence ovarian cancer development, histopathologic subtype, progression, response to therapy, and overall survival. Conclusions: Gene expression profiling has demonstrated its utility in ovarian cancer research. It is hoped that with technologic, statistical, and bioinformatic advances, the reliability and reproducibility of this technique will increase, spawning clinical applications that may enhance our understanding of the disease and our ability to care for patients in the future.
