Primary and recurrent (second-look surgery) serous epithelial ovarian cancers Illumina Infinium HumanMethylation450 BeadChip data
This dataset was generated from 16 primary and matched recurrent ovarian cancer tissue sets from patients with stage III/IV serous epithelial OC. The primary tumor specimens were collected at the time of initial debulking surgery. Recurrent tumor samples were obtained from the same patients during “second-look” surgeries. Samples were obtained and data was generated after patients provided written informed consent under protocols approved by the Duke University Institutional Review Board.
