1. A method comprising:

treating genomic DNA from a sample from a subject having or suspected of having ovarian cancer with a reagent that modifies DNA in a methylation-specific manner;

amplifying the treated genomic DNA using a set of primers specific for each of CDO1 and SIM2; and

determining a methylation level of at least one differentially methylated region (DMR) in each of CDO1 and SIM2 using polymerase chain reaction (PCR), nucleic acid sequencing, mass spectrometry, restriction enzyme analysis, mass-based separation, and/or target capture.
