• •Submission of fixed ovarian tissue (FN01) required
• •Must meet 1 of the following additional criteria:
• •* Family of the patient has a documented deleterious BRCA1 or BRCA2 mutation and either the patient herself has tested positive for a deleterious BRCA1 or BRCA2 mutation or the patient has a first- or second-degree relative with a deleterious BRCA1 or BRCA2 mutation

• •* The probability of carrying a BRCA1 or BRCA2 mutation, given the family pedigree of breast and ovarian cancers, exceeds 20%, as calculated by BRCAPRO
• •No prior history of ovarian cancer, including low malignant potential cancers, or primary papillary serous carcinoma of the peritoneum
• •No prior or concurrent history of breast cancer, including ductal carcinoma in situ (DCIS) of the breast
• •* Women with a history of hormone receptor-negative breast cancer (both estrogen receptor-negative and progesterone receptor-negative) are eligible

• •No other malignancy, including ductal carcinoma in situ, within 1 year of systemic therapy, except for nonmelanoma skin cancer
• •No prior chemotherapy regimen lasting ≥ 12 months
• •No oral or intrauterine hormonal contraception or hormonal replacement therapy within the past 3 months or injectable medroxyprogesterone within the past 12 months
• •No intraperitoneal surgery within the past 3 months (including laparoscopy)
• •No prior or concurrent radiotherapy to the pelvis
