DNA ploidy, nuclear size, proliferation index and DNA-hypomethylation in ovarian cancer

► We analyze the impact of epigenetic alterations in 70 ovarian cancer specimens. ► Correlations between DNA-hypomethylation & nuclear area are identified. ► Correlations between DNA-hypomethylation and proliferation index are identified. ► Prognostic relevance of nuclear area is revealed in mucinous ovarian cancers. ► Prognostic relevance of DNA-hypomethylation is revealed in mucinous ovarian cancers.
