The study will be conducted under an IRB approval, in accordance with FDA regulations and Human Subject Protection regulations. Female patients will undergo standard of care therapy to include exploratory laparotomy and cytoreduction (debulking) surgery followed by chemotherapy. Only patients with histological confirmation of FIGO Stage III/IV epithelial adenocarcinoma of ovarian, tubal or peritoneal origin will be screened and enrolled into the study. At cytoreduction surgery a portion of the surgically resected tumor is preserved for vaccine production. The surgically resected tumor as well as normal cells obtained from peripheral blood shall be used for extraction of RNA and DNA sequencing of the tumor and normal transcriptomes, as well as normal exome sequencing, in the Genomic Core Facility at UConn Health. Patient's blood cells shall also be HLA typed.
