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.

Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 90 days following completion of therapy. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
A female of child-bearing potential is any woman (regardless of sexual orientation, having undergone a tubal ligation, or remaining celibate by choice) who meets the following criteria

Has not been naturally postmenopausal for at least 12 consecutive months (i.e., has had menses at any time in the preceding 12 consecutive months)
Patients must be able to swallow and retain oral medications
Ability to understand and the willingness to sign a written informed consent

Exclusion Criteria

Chemotherapy, radiotherapy, or other cancer therapy within 4 weeks prior to starting study treatment. Subjects must have recovered from prior treatment-related to toxicities to grade 1 or baseline (excluding alopecia and clinically stable toxicities requiring ongoing medical management, such as hypothyroidism from prior immune checkpoint inhibitor treatment)
Subjects may not be receiving any other investigational agents for the treatment of the cancer under study
Brain metastases
History of allergic reactions attributed to compounds of similar chemical or biologic composition to Lynparza or other agents used in study
Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that, in the opinion of the investigator, would limit compliance with study requirements
Subjects must not be pregnant or nursing due to the potential for congenital abnormalities and the potential of this regimen to harm nursing infants
