Study involves surgery for cytoreduction or laparoscopy to determine if you are a candidate for tumor debulking or a tissue biopsy. Following this surgery you will receive chemotherapy. This study will administer 7 days of treatment with a targeted therapy called Lynparza. Lynparza and/or other PARP inhibitors have been FDA approved for the treatment of ovarian and breast cancer. Tissue biopsy will be done before a 7 day course of Lynparza in order to correlate molecular changes to response to treatment. Participation in this trial will require an additional tumor biopsy which will occur either before or after treatment of Lynparza.
